Altiok Tayfur (Moderator), Kelton W. David, L’Ecuyer Pierre, Nelson Barry L., Schmeiser Bruce W., Schriber Thomas J., Schruben Lee W., Wilson James R. Various ways academics teach simulation: are they all appropriate? (panel on education in simulation) // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.1580-1591.
This panel discusses goals and educational strategies for teaching simulation in academia. Clearly, there is considerable material to cover in a single course or a sequence thereof in, say, an undergraduate program. The issue is how to motivate and empower students to analyze complex problems correctly and to prevent the pitfall of misusing the concept.

The combination of simulation and optimization, essentially unheard of in practice a decade ago, is much more accessible today, thanks in large part to the development of commercial optimization software designed for use with existing simulation packages. Despite this growth, untapped applications abound. This panel, which includes developers of simulation-optimization packages, will discuss this untapped potential, barriers to broader applicability, and approaches for overcoming these barriers. This paper starts off with a brief introduction by the panel’s organizer, followed by position statements from the panelists.

This paper presents an application of computer simulation as a policy analysis tool for the electric utility industry. In the last decade, the amount of electricity generation capacity has remained constant while demand for electricity has been increasing. This situation puts industrial electricity users, those who use large highly varying quantities of electricity in potentially risky production and financial situations. In this paper, we describe a computer simulation model that examines the electricity requirements of a steel mill in a constrained electricity supply environment. By using simulation, we develop and analyze policies that quantify the costs and benefits of collaborative strategies for efficient electricity usage from both perspectives.

Over the years, simulation models have been successfully built to observe the behavior of systems. Despite advances in the field and its growth in popularity, when simulation is to be introduced to an organization, there are challenges to be met including acceptance by staff, availability of staff to describe the various operations, existence of useful data, and management expectations. Organizations are continuously collecting data, which may lead one to believe that developing stochastic models of an organization’s activities should be easy. However, elicitation of useful information may end up being a major bottleneck because usually the information system collecting such data is not designed for stochastic modeling.

Chatfield Dean C., Harrison Terry P., Hayya Jack C. SISCO: A supply chain simulation tool utilizing SILK and XML // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.614-622.
We discuss SISCO, the Simulator for Integrated Supply Chain Operations, a Java-based tool that simplifies supply chain simulation model development. SISCO maps supply chain descriptions stored in the XML-based Supply Chain Modeling Language format to a set of supply chain «building blocks» developed with ThreadTec’s Silk simulation classes. The resulting system combines the ease of a visual supply chain simulator, the power and flexibility of a full object-oriented programming language, and the unparalleled supply chain model detail of a new, open, information standard.

MedModel is a simulation tool that allows healthcare engineers, managers and clinicians to quickly examine very complex operational and planning issues. Unlike static tools, such as spreadsheets, MedModel makes it easy to replicate the complex interactions within and between departments. These interactions quickly create problems that are simply too complex for traditional tools to answer properly. MedModel has a wealth of specific functions to accurately duplicate actual health system behavior. This paper is an examination of how capable this tool is in answering complex healthcare planning questions.

This paper focuses on the use of discrete event simulation to address the many traffic related issues brought on by this more aggressive inventory method. The model considered factors such as plant schedule, gate staffing, vehicle production, truck size, travel time, vehicle speed, loading time, and marshalling requirements. The results of the project have helped vendors understand how much time to allow for travel within the General Motors site once the truck arrives with its parts. The paper will also discuss the role 3D simulation played in validating this model and communicating specific simulation results.

Air traffic delay is a growing and expensive problem. We investigated ways to reduce the cost and magnitude of such delays by trading gate delays against more expensive air delays. Air management and planning at this level can be facilitated by simulation, especially for strategies that alter controls on the system. We used the SIMMOD air traffic simulation to model the system. The objective was to determine a set of control measures that achieve the best system performance subject to restrictions on the decision parameters and selected system output measurements. Our approach used the simultaneous perturbation stochastic approximation algorithm with a penalty function to handle the difficult constraints.

Kiran Ali S., Cetinkaya Tekin, Cabrera Juan. Hierarchical modeling of a shipyard integrated with an external scheduling application // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.877-881.
This paper presents a hierarchical approach on the simulation of large-scale discrete event systems used recently by Kiran Consulting Group to model shipyard operations. Because of the dynamic, stochastic and complex nature of the shipbuilding processes, bottleneck identification and estimation of the impact of new technology implementation is extremely difficult to derive via analytical methods. The simulation model of a large-scale discrete event system can be considered as a collection of sub-systems, which are represented by the simulation models that are independently created, modified, and saved.

Krahl David. The Extend simulation environment // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.217-225.
The Extend simulation environment provides an integrated structure for building simulation models and developing new simulation tools. This environment supports simulation modelers on a wide range of levels. Model builders can use Extend’s pre-built modeling components to quickly build and analyze systems without programming. Simulation tool developers can use Extend’s built-in, compiled language, ModL, to develop new reusable modeling components. All of this is done within a single, selfcontained software program that does not require external interfaces, compilers, or code generators.

An intermodal rail terminal is a facility where the transfer of cargo occurs between truck and rail. The operations within these terminals involve many resources and operating rules. The ability of a terminal to respond to activity peaks that occur as a result of train arrivals and departuresis critical. In order to explore how operations can be improved given the dynamics of resource and demand interactions, a simulation model was developed to assist in understanding and exploring areas where throughput can be improved. The model was constructed such that capacity issues could be explored incrementally. The first focus was for understanding if efficient deployment of labor resources could provide desired throughput.

Law Averill M., McComas Michael G. How the expertfit distribution-fitting software can make your simulation models more valid // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.256-261.
In this paper, we discuss the critical role of simulation input modeling in a successful simulation study. Two pitfalls in simulation input modeling are then presented and we explain how any analyst, regardless of their knowledge of statistics, can easily avoid these pitfalls through the use of the ExpertFit distribution-fitting software. We use a set of real-world data to demonstrate how the software automatically specifies and ranks probability distributions, and then tells the analyst whether the «best» candidate distribution is actually a good representation of the data. If no distribution provides a good fit, then ExpertFit can define an empirical distribution. In either case, the selected distribution is put into the proper format for direct input to the analyst’s simulation software.

In this tutorial we present techniques for building valid and credible simulation models. Ideas to be discussed include the importance of a definitive problem formulation, discussions with subject-matter experts, interacting with the decision-maker on a regular basis, development of a written conceptual model, structured walk-through of the conceptual model, use of sensitivity analysis to determine important model factors, and comparison of model and system performance measures for an existing system (if any). Each idea will be illustrated by one or more real-world examples. We will also discuss the difficulty in using formal statistical techniques (e.g., confidence intervals) to validate simulation models.

Leemis Lawrence. Input modeling techniques for discrete-event simulations // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.62-73.
Most discrete-event simulation models have stochastic elements that mimic the probabilistic nature of the system under consideration. A close match between the input model and the true underlying probabilistic mechanism associated with the system is required for successful input modeling. The general question considered here is how to model an element (e.g., arrival process, service times) in a discrete-event simulation given a data set collected on the element of interest. For brevity, it is assumed that data is available on the aspect of the simulation of interest. It is also assumed that raw data is available, as opposed to censored data, grouped data, or summary statistics. This example-driven tutorial examines introductory techniques for input modeling.

A car-following and lane-changing microsimulation model of a two-lane road section has been written in SLX as part of an extensive research project by the University of Rome Transport Department to qualify and quantify the environmental impact of traffic. The microsimulation model is part of a three-step approach, involving a traditional transport macroscopic model, the microscopic model, and an ultra-micro model. The microsimulation model’s car-following and lane-changing rules are presented and described in detail, and model outputs are commented.

In models of military operations it is important to include the Command and Control (C2) process in order to achieve a realistic simulation of a military force’s behaviour and effectiveness. Inspired by ideas from complexity theory we have developed a representation of C2 based on a decentralized system of interacting intelligent «command agents». In this paper we describe the architecture of our command agents and how this captures the key C2 processes that exist in military headquarters, particularly the G2 and G3 processes of recognised picture compilation, decision making and planning. We describe a re-usable software framework that we have developed, within which we implement the command agents.

McLean Charles, Shao Guodong. Simulation of shipbuilding operations // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.870-876.
This paper discusses the objectives and requirements for a shipbuilding simulation. It presents an overview of a generic simulation of shipbuilding operations. The shipbuilding simulation model can be used as a tool to analyze the schedule impact of new workload, evaluate production scenarios, and identify resource problems. The simulation helps identify resource constraints and conflicts between competing jobs. The simulation can be used to show expected results of inserting new technologies or equipment into the shipyard, particularly with respect to operating costs and schedule impact.

Nicol David M. Discrete event fluid modeling of TCP // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D J. Medeiros, and M.W. Rohrer, eds. P.1291-1299.
The bulk of Internet traffic is carried using variants of the TCP protocol. A realistic simulation-based performance study of any distributed application run over the Internet (e.g. reliable multicast) must therefore account for the impact that TCP background traffic has upon application behavior. Because TCP flows are shaped by other TCP flows, it is difficult to model TCP and its impact on other traffic other than by explicitly simulating it. This adds a significant computational burden to the simulation. This paper describes how we use fluid-based models of TCP to reduce the computational workload of simulating background TCP traffic.

Nordgren William B. Taylor Enterprise Dynamics // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.269-271.
Taylor Enterprise Dynamics (Taylor ED) is an object-oriented software system used to model, simulate, visualize, and monitor dynamic-flow process activities and systems. Atoms are Taylor ED’s smart objects and model building resources. In addition to Taylor ED’s standard atom libraries, users can create new atoms themselves. Taylor ED’s object-oriented architecture provides users with the ability to enhance and increase the functionality of the Taylor ED software system. It also provides simulation experts with a platform on which to create new simulation software programs for specific industries or for specific applications. Historically, Taylor ED has been used to model manufacturing, warehousing, and material handling processes.

This paper describes an architecture for the simulation of a transportation system that uses agent technology to deliver people and goods from their origins to their destinations. The intent of the architecture is to analyze incremental changes to the existing transportation paradigm to determine what type of system we could plan for in the future. Each entity within the system that has computational power is simulated as an agent. This architecture is useful for experimenting with many different algorithms and strategies for improving transportation systems.

Each panelist has contributed written perspectives describing aspects of his involvement with GPSS. A Geoffrey Gordon memoriam is included in the paper. (Geoffrey Gordon, who conceived and evolved the idea for GPSS and brought about its IBM implementations, died in 1989.)

Schulze Thomas, Lemessi Marco, Filippi Francesco. Simulation of a night taxi-bus service for the historical center of Rome // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.1072-1078.
The Municipality of Rome plans to introduce a taxi-bus system as a night service. A micro-simulation model was developed to estimate the needed information. Two major topics regarding this model are presented. First, the iteration process for input parameters is described. The number of potential customers is determined by means of an external modal split model. Two input parameters for the external model are estimated by the micro-simulation model. An iteration process was used. The second topic is the integration of an optimization model into the micro-simulation model. Both simulation and optimization components were implemented in the simulation system SLX.

Schunk Daniel W., Bloechle Wendy K. Simulation interoperability with the micro saint simulation software and com services // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.239-245.
In today’s high tech world the need for interoperability among programs has never been more necessary. If a user were able to utilize different programs’ strengths in unison, then the ability for programs to work together would greatly expand current software’s ability to analyze. In response to this request, COM Services was added to the most recent release of Micro Saint. This paper will feature an example of how to apply interoperability to the Micro Saint simulation software as well as present some examples of how to further utilize COM Services.

Stahl Ingolf. GPSS - 40 years of development // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.577-585.
This year GPSS celebrates its 40th birthday. This paper reports on the development during these 40 years, starting with the first version developed by Gordon at IBM in 1961, and the following development of GPSS II, GPSS III, GPSS/360 and GPSS V, all IBM products. A major section is devoted to GPSS/H, which has dominated the GPSS scene during the last years. There is one section on the GPSSR family of GPSS versions and one on GPSS/PC and GPSS World. There are also many GPSS systems, projects and ideas of a mainly academic nature. A great number of GPSS textbooks are noted. The concluding section discusses the reasons for the popularity of GPSS.

Stanley Brian. The AutoMod product suite tutorial // Proceedings of the 2001 Winter Simulation Conference B.A. Peters, J.S. Smith, D.J. Medeiros, and M.W. Rohrer, eds. P.209-216.
Whether designing a new system or modifying an existing one, engineers want to take the guesswork out of finding the best possible solution. While there are many analysis methods for designing industrial systems, simulation remains the method that provides the highest level of confidence that a system will perform. A well-written simulation model can be a valuable tool in the design, analysis, and operation of manufacturing and other complex systems. The AutoMod has been used on 1000s of projects to help engineers and managers make the best decisions possible.

The success of a computer simulation project depends greatly on the effectiveness of simulation statistical analysis. Internet asynchronous web learning reduces the workload of classroom teaching. To help the novice learn better simulation problem solving, this research addresses designing the usability into computer-based training (CBT) environment by focusing on the simulation experience and the interaction design. A prototype asynchronous web CBT system was built for validating our design via a three-stageformative usability evaluation.

This paper considers advantages and actual problems of web based simulation systems. Based on a review of environments and languages for web based simulation, some fundamental requirements for successful simulations are presented. The goal is to change the technology-driven approach in a more customer oriented philosophy. The common concept of «Application Service Providing (ASP)» should be understood as a future technology for web based simulation environments. The paper presents a real Simulation ASP. The system is based on a database for all model and simulation data.
