ProModel Salutes Founder Charley Harrell for Years of Service…and Getting This Whole Thing Started!

by

Dr. Charles Harrell founded ProModel in 1988 and was the original developer of the Company’s simulation technology (ProModel PC). Today he serves on the Board of Directors and has been actively involved in new product development, acting as chief technology advisor.  Charley is also an associate professor of Engineering and Technology at Brigham Young University and the author of several simulation books.

Retirement PicsIn May, Charley officially retired from the company and to honor his innovative and productive career ProModel held two celebrations this summer at two of our locations in Orem Utah and Allentown Pennsylvania.  The events were attended by ProModel staff and many of Charley’s long time colleagues who have been with him from the start.

In recent years, Charley has written about his team’s original vision for ProModel back in 1988, “We set out to revolutionize the use of simulation in the business world by introducing the first graphically oriented simulation tool for desktop computers.  We were all convinced that we offered a unique product—a simulation tool that was developed and supported by engineers and specifically designed for engineers.”

Describing the success of ProModel Corporation, Charley writes, “In addition to the impressive growth in ProModel’s predictive simulation technology, it has also been gratifying to see the breadth of application of our technology, not just in fortune 500 companies, but also in the area of healthcare, education, homeland security, military readiness and humanitarian aid.”

The entire ProModel family would like to thank Charley for his years of service, guidance and friendship and we wish him all the best in the future! He has made ProModel what we are today.

In 2013 ProModel celebrated its 25th  Anniversary and Charley shared his memories and appreciation for ProModel in this thoughtful BLOG POST

Simulating Impatient Customers

Dr. Farhad Moeeni 

Simulation is one of the required courses for the MBA degree with MIS concentration at Arkansas State University.  The course was developed a few years ago with the help of a colleague (Dr. John Seydel).  We use Simulation Using Promodel, Third Ed. (Harrell, et al., Ghosh and Bowden, McGraw-Hill) for the course.  In addition, students have access to the full-version of the Promodel software in our Data Automation Laboratory. The course has attracted graduate students from other areas including arts and sciences, social sciences and engineering technology who took the course as elective or for enhancing research capability.  Students experience the entire cycle of simulation modeling and analysis through                                          comprehensive group projects with a focus on business decision making.

Most elements of waiting lines are shared by various queuing systems regardless of entity types such as human, inanimate, or intangible.  However, a few features are unique to human entities and service systems, two of which are balking and reneging.  One of the fairly recent class projects included modeling the university’s main cafeteria with various food islands. Teams were directed to also model balking and reneging, which was challenging. The project led to studying various balking and reneging scenarios and their modeling implications, which was very informative.

Disregarding the simple case of balking caused by queue capacity, balking and reneging happens because of impatience.  Balking means customers evaluate the waiting line, anticipate the required waiting time upon arrival (most likely by observing the queue length) and decide whether to join the queue or leave. In short, balking happens when the person’s tolerance for waiting is less than the anticipated waiting time at arrival.  Reneging happens after a person joins the queue but later leaves because he/she feels waiting no longer is tolerable or has utility.  Literature indicates that both decisions can be the result of complex behavioral traits, criticality of the service and service environment (servicescape). Therefore, acquiring information about and modeling balking or reneging can be hard.  However, it offers additional information on service effectiveness that is hard to derive from analyzing waiting times and queue length.

For modeling purposes, the balking and reneging behavior is usually converted into some probability distributions or rules to trigger them. To alleviate complexity, simplified approaches have been suggested in the literature.  Each treatment is based on simplifying assumptions and only approximates the behavior of customers. This article addresses some approaches to simulate balking.  Reneging will be covered in future articles.  Scenarios to model balking behavior include:

  1. On arrival, the entity joins the queue only if the queue length is less than a specified number but balks otherwise.
  2. On arrival, the entity joins the queue if the queue length is less than or equal to a specified number. However, if the length of the queue exceeds, the entity joins the queue with probability  and balks with probability  (Bernoulli distribution).
  3. The same as Model 2 but several (Bernoulli) conditional probability distribution is constructed for various queue lengths (see the Example).
  4. On arrival, a maximum tolerable length of queue is determined from a discrete probability distribution for each entity. The maximum number is then compared with the queue length at the moment of arrival to determine whether or not the entity balks.

The first three approaches model the underlying tolerance for waiting implicitly.  Model 4 allows tolerance variation among customers to be modeled explicitly.

A simulation example of Model 3 is presented. The purpose is to demonstrate the structure of the model and not model efficiency and compactness.  The model includes a single server, FCFS discipline, random arrival and service.  The conditional probability distributions of balking behavior are presented in the table. The data must be extracted from the field.  The simulation model is also presented below. After running the models for 10 hours, 55 (10% of) customers balked. Balking information can be very useful in designing or fine-tuning queuing systems in addition to other statistics such as average/maximum waiting time or queue length, etc.

Condition

Conditional Probability Distribution
Probability of Joining the Queue (p) Probability of Balking (1-p)
Queue Length <= 4 1.00 0
5<=Queue Length <= 10 0.7 0.3
Queue Length > 10 0.2 0.8

Dale Schroyer – Sr. Consultant & Project Manager

I generally find that in healthcare, WHEN something needs to happen is more important than WHAT needs to happen.  It’s a field that is rife with variation, but with simulation, I firmly believe that it can be properly managed.  Patient flow and staffing are always a top concern for hospitals, but it’s important to remember that utilization levels that are too high are just as bad as levels that are too low, and one of the benefits of simulation in healthcare is the ability to staff to demand.

Check out Dale’s work with Robert Wood Johnson University Hospital where they successfully used simulation to manage increased OR patient volume:

Teaching Simulation to Graduate Students Using ProModel Products and Real-World Problems

by

ProModel Guest Blogger:  Larry Fulton, Ph.D. & MSStat – Assistant Professor of Health Organization Management at Texas Tech University Rawls College of Business.  After serving 25 years in military medicine, Dr. Fulton began a second career in teaching and research.

Larry Fulton, Ph.D. & MSStat

Larry Fulton, Ph.D. & MSStat

Teaching introductory Monte Carlo, Discrete Event, and Continuous simulation to business graduate students requires at least two components beyond a good set of reference materials:   realistic or real-world problems and an excellent modeling platform allowing for relatively rapid development.  In the case discussed here, the real-world scenarios derived from interests and background of the professor and students (portfolio analysis, sustainability, and military medicine), while ProModel products addressed the platform requirements. Each of the case study  scenarios served to underscore various simulation building elements, while ProModel supported rapid  product development for a 14-week, lab-intensive course that included some  reviews of probability, statistics, queuing, and                                                    stochastic processes.

Scenario 1:  Monte Carlo Simulation (Portfolio Analysis)

Business students generally have an affinity for portfolio analysis, and I do as well. Using ProModel  features, one of the earliest student projects involves fitting univariate distributions to return rates to several funds and simulating results of investment decisions of various time horizons.  Students discuss methods that might account for covariance as well as autoregressive components in these simulations.  While developing the simulations, students also determine sample size requirements to bracket mean return on investment within a specified margin of error and confidence interval and use random numbers seeds.

Scenario 2:  Continuous Simulation using Rainwater Harvesting

Students in this course are generally from a semi-arid region (Central Texas), which has significant water shortages (so much so that desalinization is being considered.)  I rely 100% on rainwater harvesting for my home water supply, so extending this to each student’s particular home location is trivial. The “Tank Submodule” provides an easy mechanism for developing the simulations.  Students develop conceptual models of rainwater mechanism as well as flowcharts.  They gather rainfall data from the National Oceanic and Atmospheric Administration regarding rainfall and evaluate various roof sizes (capture space), demand figures based on occupants, and tank sizes. They also learn about the importance of order statistics (the distribution of the minimum in the tank) versus measures of central tendency that often dominate discussions of simulation. Finally, they incorporate tools and techniques to improve and assess V&V.

­­­Scenario 3:  Discrete Event Simulation using Military Scenarios

While serving as the Chief of Operations Research Branch for the Center for Army Medical Department Strategic Studies, I encouraged the use of MedModel for multiple DES projects.  The team built strategic models (resource constrained and unconstrained) for analyzing medical requirements for strategic operations. These same models serve as a basis for a team-based MedModel student capstone project.  The primary entity for these models was the patient with attributes of severity, injury type, and evacuation type.  The primary processes involved collection, treatment and evacuation. Resources included ground ambulances, air ambulances, medics, intensive care units, and operating rooms.   Locations were geographic locations throughout the entire of Afghanistan.  Evacuation paths were built, and treatment logic (triage, ground evacuation, air evacuation, etc.) provided the flow.

Bottom Line:  The ProModel products are outstanding for use in both teaching and industry.

Teaching Process Management Using ProModel

by

ProModel Guest Blogger:  Scott Metlen, Ph.D. – Business Department Head and Associate Professor at University of Idaho

Scott Metlen, Ph.D.

Scott Metlen, Ph.D.

Understanding process management, the design, implementation, management and control, and continuous improvement of the enterprise wide set of an organizations processes is the key to well deployed strategies. It was not until Tim Cook made Apple’s total set of processes world class including all supply chain linked processes (Brownlee, 2012) that Apple hit its amazing climb to become the world’s highest valued company; even though the company had cutting edge products before his arrival. Gaining effective understanding of process management is not easy due to the strategic variability inherent in the portfolio of products that companies sell, and in markets they service. This strategic variability (Rajan, 2011) in turn drives variability in many processes that an organization uses to operate. For instance, different markets require different marketing plans supported by different processes.  Order processes often vary by product and target market. Employee skill sets differ by product requiring different hiring and training processes. Different products, whether it be services or goods that have a slight variation require, at the very least, an adjustment to the production process. Adding to, and often caused by the variability just mentioned, are multiple process steps, each with different duration times and human resource skills.  Depending on what product is currently being produced, process steps, process step order and duration time, interdependency between the process steps, and business rules all vary. Where a product is in its life cycle will drive the experience curve, again creating variation across products. In addition, the numerous interfaces with other processes all vary depending on the product being produced. All of these sources of variability can make process management hard to do, teach, and learn. One tool that helps with process management in the face of variance is discrete event simulation and one of the best software suites to use is ProModel. ProModel is a flexible program with excellent product support from the company.

Effective process management is a multi-step process. The first step of process management is to determine the process flow while at the same time determining the value and non-value added process steps. Included in the process flow diagram for each step are the duration times by product and resources needed at each step, and product routes. Also needed at this time are business rules governing the process such as working hours, safety envelopes, quality control, queueing rules, and many others. Capturing this complex interrelated system begins by visiting the process and talking with the process owner and operators. Drawing the diagram and listing other information is a good second step, but actually building and operating the process is when a person truly understands the process and its complexities.  Of course many of the processes we want to improve are already built and are in use. In most cases, students will not be able to do either of these. However, building a verified and validated simulation model is a good proxy for doing the real thing, as the model will never validate against the actual process output unless all of the complexity is included or represented in the model. In the ‘Systems and Simulation’ course at the University of Idaho students first learn fundamentals of process management including lean terms and tools. Then they are given the opportunity to visit a company in the third week of class as a member of a team to conduct a process improvement project. In this visit students meet the process owner and operators. If the process is a production process, they walk the floor and discuss the process and the delta between expected and actual output. If the process is an information flow process, such as much of an order process, the students discuss the process and, again, the delta between expected and realized output. Over the next six weeks students take the preliminary data and begin to build a simulation model of the current state of the process. During this time period students discover that they do not have all the data and information they need to replicate the actual process. In many cases they do not have the data and/or information because the company does not have that information or how the model is operated is not the same as designed. Students then have to contact the process owner and operators throughout the six weeks to determine the actual business rules used and/or make informed assumptions to complete their model.

Once the model has been validated and the students have a deep understanding of the process, students start modeling process changes that will eliminate waste in the system, increase output, and decrease cost. Examples of methods used to improve the process include changing business rules, adding strategically placed buffers and resources, and reallocating resources. To determine the most effective way to improve the process, a cost benefit analysis in the form of an NPV analysis is completed. The students use the distribution of outputs from the original model to generate appropriate output and then compare that output to output pulled from the distributions of each improvement scenario. This comparison is then used to determine a 95% confidence interval for the NPV and the probability of the NPV being zero or less. Finally, several weeks before the semester is finished, students travel to the company to present their findings and recommendations.

Student learning on these projects is multifaceted. Learning how to use ProModel is the level that the students are most aware of during the semester, as it takes much of their time. However, by the end of the semester they talk about improving their ability to manage processes, work in teams, deal with ambiguity, manage multiple projects, present to high level managers, and maintain steady communication with project owners.

Utilizing external projects and discrete event simulation to teach process management has been used in the College of Business and Economics at the University of Idaho for the past six years. As a result, the Production and Operation area has grown from 40 to 150 students and from five to 20 projects per semester. More importantly, students who complete this course are being sought out and hired by firms based on the transformational learning and skill sets students acquired through the program.

Demystifying System Complexity

by
Charles Harrell, Founder ProModel Corporation

Charles Harrell, Founder ProModel Corporation

One can’t help but be awe struck, and sometimes even a little annoyed, by the complexity of modern society. This complexity spills over into everyday business systems making them extraordinarily challenging to plan and operate. Enter any factory or healthcare facility and you can sense the confusion and lack of coordination that often seems to prevail. Much of what is intended to be a coordinated effort to get a job done ends up being little more than random commotion resulting in chance outcomes. Welcome to the world of complex systems!

A “complex system” is defined as “a functional whole, consisting of interdependent and variable parts.” (Chris Lucas, Quantifying Complexity Theory, 1999, http://www.calresco.org/lucas/quantify.htm) System complexity, therefore, is a function of both the interdependencies and variability in a system. Interdependencies occur when activities depend on other activities or conditions for their execution. For example, an inspection activity can’t occur until the object being inspected is present and the resources needed for the inspection are available. Variability occurs when there is variation in activity times, arrivals, resource interruptions, etc. As shown below, the performance and predictability of a system is inversely proportional to the degree of interdependency and variability in the system.

Untitled-1

Suppose, for example, you are designing a small work cell or outpatient facility that has five sequential stations with variable activity times and limited buffers or waiting capacity in between. Suppose further that the resources needed for this process experience random interruptions. How does one begin to estimate the output capacity of such a system? More importantly, how does one know what improvements to make to best meet performance objectives?

Obviously, the larger the process and greater the complexity, the more difficult it is to predict how a system will perform and what impact design decisions and operating policies will have. The one thing most systems experts agree on, however, is that increasing complexity tends to have an adverse effect on all aspects of system performance including throughput, resource utilization, time in system and product or service quality.

For Charleys new blog

ProModel and Medmodel are powerful analytic tools that are able to account for the complex relationships in a system and eliminate the guesswork in systems planning. Because these simulation tools imitate the actual operation of a system, they provides valuable insights into system behavior with quantitative measures of system performance.

To help introduce process novices to the way interdependencies and variability impact system performance, ProModel has developed a set of training exercises using an Excel interface to either ProModel or MedModel. Each exercise exposes the initiate to increasingly greater system complexity and how system performance is affected. Additionally, these exercises demonstrate the fundamental ways system complexity can be mitigated and effectively managed.

ProModel is offering these exercises to students and practitioners who are seeking an introduction to simulation and systems dynamics.

Same Venue, Different Challenges

by
Weeds Pic

Rob Wedertz – Director, Navy Programs

Just a few weeks ago, I had the privilege of attending the Tail Hook Association’s annual conference in Reno, Nevada.  It is the first time I attended the conference not as an active duty member of the Naval Aviation community, but as a vendor supporting the enterprise through our role as the software application provider of the Naval Synchronization Toolset.  Surprisingly, other than keeping much different hours and standing on the opposite side of the booth table, the conference felt much like it did every year I have attended in the past.  There were many “so what are you doing these days?” conversations with old friends and the ever-present aura of “Naval Aviation is special because…” throughout the exhibit hall.

In fact, had I not taken the opportunity to attend some of the panels and engage some of our key stakeholders in pointed conversations it would have been extremely difficult to differentiate this year’s conference from any other I had attended over the last 2 decades.  There was a new vernacular that weaved its way into this year’s conference.  Words like “sequestration”, “draw-down”, and “budget constraints” permeated the Rose A ballroom, and for the first time in many years, I sensed a palpable uncertainty among the leadership of Naval Aviation as they extolled the virtues of tail hook aviation’s role in the world theatre against the backdrop of future shoe string budgets and unknown war fighting requirements.  (Ironically, the Air Boss told a poignant story of a “nugget” strike fighter pilot from CVW-8 expertly delivering ordnance in the fight against ISIS the same day the morning news detailed the withdrawal of forces from Afghanistan as “hostilities in the Middle East come to a close”.)

Given the environment we’re in and the abundance of questions marks hovering over the next several years, it should come as no surprise that many attendees, including most of the NAE leadership took a great deal of interest in the “little” ProModel booth nestled among missile mock-ups, Joint Strike Fighter simulators, and high-tech defense hardware displays.  In fact, as one of the very few (if not the only) predictive/prescriptive analytics software vendors in attendance at Hook ’14, we were an anomaly.

Tailhook '14

ProModel’s Keith Vadas and Carl Napoletano speak with VADM Dunaway, Commander, Naval Air Systems Command

 

A common theme emerged during our discussions with visitors and through comments made during the various panel discussions – decisions must be made via actionable data, courses of action must be modeled and validated, and technology-enabled decision support applications must be agile enough to get an answer in short order.  Thus the interest in ProModel.

While the Naval Synchronization Toolset is in its infancy from a relative viewpoint (we achieved initial operating capability just a year ago), ProModel has been delivering enterprise-wide decision support tool capabilities to its customers (both private and DoD) for over 25 years.  As industries have evolved (adopted Lean Six Sigma methodologies, harnessed data collection and aggregation, and leveraged emerging technologies) so has ProModel.  We have learned, alongside our customers, that there is significant “power” in diminishing uncertainties through “what-if” analysis and exploration of alternatives via technology-enabled decision support tools like the NST.  The questions the NAE gets asked have answers and it is discovering that getting there is a matter of adopting a philosophy that centers around modeling the behavior of the system, deciding on dials (variables), and exploring the alternatives.

The NST is that system.  Through our integration efforts with Veracity Forecasting and Analysis, we have delivered a software application that establishes the demand signal (the Master Aviation Plan module), models the behavior of the system (Carrier Strike Group Schedule, Air Wing Schedules, and Squadron Schedules), models the behavior of elements (the Airframe Inventory Management module) the utilization of the FA-18 A-F inventory over time, and provides a “sandbox” environment that facilitates optimal disposition of assets in order to meet the requirements of the NAE over time.

We heard, during our attendance at Hook ’14, that the optimal management of the FA-18 inventory was one of the focal points of the NAE leadership.  And although we’ve been involved in the development efforts of the NST for more than 2 years, it is the first time that the challenges of inventory management have taken center stage at a venue that has long been unchanged and timeless.  We felt privileged to be among the professionals in attendance at Hook ’14 and even more proud to be an integral part of the solution set to Naval Aviation’s challenges going forward.  We’ll be back next year and hope that the NAE is no longer talking about it.

Designing Better Care For Your OR

JCowden Profile Pic

Jennifer Cowden – Sr. Consultant

Earlier this year, my family and I took a vacation to a certain kid-friendly theme park.  As we wandered from ride to ride, we couldn’t help but note that, even at the peak times on the more popular rides, you rarely saw crowds standing outside waiting. The long lines were all contained within a succession of fairly climate-controlled rooms that obviously took some thought to plan. This particular company is big into predictive analytics, so I would hazard to say that they didn’t just guess at the maximum size of the line at peak time; they are probably not going to go live with a new attraction or other big change unless they simulate it first.  An interesting dynamic that we observed was that when a wait time for an attraction was lowered on their new mobile app, we could literally see the “flash mob” of patrons converge on that ride, causing the line to go from a 10-minute wait to a 30-minute wait in the blink of an eye.  I turned to my husband, who is also an engineer and a geek, and said “I wondered if their model predicted that.”

Theme parks obviously need to be concerned about a positive overall  visitor experience; after all, they are always competing for discretionary funds with other sources of entertainment.  Now, more and more hospitals are developing that same mindset: being cognizant of the overall patient experience to the point of modeling new spaces before they go live.  How many OR rooms should they outfit for opening day, and how many can wait?  How can they make the best use of the spare rooms?    Is there enough space in the corridors that the patients won’t feel too crowded?  Is there enough space in the waiting areas for the families of the outpatients?  How many staff members do they need for each department to minimize patient wait time?  Are there any unforeseen bottlenecks due to sudden dynamic shifts?  These are just a few of the questions that simulation can answer.

Busy Season at ProModel

by
Keith Vadas

Keith Vadas – ProModel President & CEO

I am pleased to report ProModel’s second quarter was very positive.  Like many businesses in the US we find ourselves on a serious upswing this Summer of 2014.  Our consultants are working on several projects in a variety of industries, including ship building, power management, retail, manufacturing, food processing, and government contracting.  In all of these projects our experienced team of consultants is working to improve efficiency, save money, and make better decisions for their clients.

ProModel’s DOD projects continue to thrive.  It is hard to believe it has been eight years since we started working with FORSCOM (US Army Forces Command)   on AST (ARFORGEN SYNCHRONIZATION TOOL).  LMI-DST (Lead Materiel Integrator – Decision Support Tool) with the LOGSA Team (US Army Logistics Support Activity) is also going strong.  Our agile team of software developers keeps improving the development process within ProModel and it shows. Just recently the NST Airframe Inventory Management Module was Granted Full Accreditation by the Commander, Naval Air Systems Command.

The time is also ripe for opportunities in Healthcare.  Our patient flow optimization capabilities are perfect for helping hospitals and outpatient clinics improve efficiencies.  Now that the Affordable Care Act has been around for a couple of years, its impact is being felt by healthcare organizations around the country.  The expanded insured-base, and the need for improved processes and different care models is making it absolutely necessary to consider the value of modeling and simulation.  ProModel continues to work with several facilities including Presbyterian Homes and Services, and Array Architects who enhance the flow in Healthcare Facilities design by using MedModel simulation in their design processes.

To better support our base of existing customers, we just released ProModel/MedModel 2014 in July and PCS Pro 2014 at the end of Q1.  EPS 2014 (Enterprise Portfolio Simulator) was released in Q2  and includes a new easy to use, web-based rapid scenario planning tool – Portfolio Scheduler.  You can check this tool out online at – http://portfoliostud.io/#.

There continue to be lots of exciting things happening at ProModel.  We have an outstanding team of consultants and software developers-designers just looking for an opportunity to PARTNER with you to help you meet the next business challenge, or solve the next unexpected problem.
