In this article authors represent an introduction to simulation based optimization, which is, perhaps, the .hottest. topic in discrete-event simulation today. We give a precise statement of the problem being addressed and also experimental results for two commercial optimization packages applied to a manufacturing example with seven decision variables.

Leemis Lawrence.. Input modeling // In: Proceedings of the 2000 Winter Simulation Conference (Joines, J.A, Barton, R.R., Kang, K. and Fishwick, P.A., eds). 2000. P.17-25.
Discrete-event simulation models typically have stochastic elements that mimic the probabilistic nature of the system under consideration. Successful input modeling requires a close match between the input model and the true underlying probabilistic mechanism associated with the system. The general question considered here is how to model an element 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.

Quasi-Monte Carlo methods are designed to improve upon the Monte Carlo method for multidimensional numerical integration by using a more regularly distributed point set than the i.i.d. sample associated with Monte Carlo. Lattice rules are one family of quasi-Monte Carlo methods, originally proposed by Korobov in 1959. In this paper, we explain how randomized lattice rules can be used to construct efficient estimators for typical simulation problems, and we give several numerical examples. We are interested in two main aspects: Studying the variance of these estimators and finding which properties of the lattice rules should be considered when defining a selection criterion to rate and choose them. Numerical results for three different problems illustrate how this methodology typically improves upon the usual Monte Carlo simulation method.

With the increasing demand for public transportation due to congested highways, trains have become one of the most viable alternatives, especially for daily commuting. While transit agencies are excited with the increasing ridership, they are also challenged with a higher volume of passenger flow and longer queuing lines at the existing stations. To improve the current situation and plan for the future, transit agencies are using simulation tools to help evaluate station design, queue management, fare equipment design and fare policy impacts.

Discrete event simulation can be used for virtual prototyping of new manufacturing facilities. Models built for this purpose must be easy to use, flexible, and provide a realistic graphical view of the proposed system. The DESTINY project has developed models of plate processing operations to assist shipyards in modernizing their plate fabrication lines. Configuration information for a proposed line is collected via a Web interface, which then launches a program to build and execute a simulation of the system. Graphics images and statistical reports are then returned to the user via the Web interface. The approach allows rapid analysis of technology improvements and a visualization of proposed system operation.

The need to understand dynamic behavior in auctions is increasing with the popularization of online auctions. Applications include designing auction mechanisms, bidding strategies, and server systems. We describe simulations of a typical online auction, where the duration is fixed, and the second-highest price is continuously posted and determines the winners payment. We modeled agents of exactly two types, idealizations and simplifications of those observed in practice: early bidders, who can bid any time during the auction period, and snipers, who wait till the last moments to bid.

Discrete event simulation is frequently time-consuming either because modern dynamic systems, such as telecommunication networks, are becoming increasingly complex and/or a great number of observations is required to yield reasonably accurate results. An interesting approach to reduce the time duration of simulation is that of concurrently running multiple replications in parallel on a number of processors connected via networking and averaging the results adequately. We present the results of our research on the suitability of batch-means-based procedures in such distributed stochastic simulation.

P.1068-1074.
The Argentine Air Force and the Brazilian Navy recently added the Douglas A-4 Skyhawk aircraft to their military services. Each country maintains its own limited repair facility and spare parts inventory. Major repair work must be sent to the manufacturers in the United States, and the long repair cycle times adversely affect military readiness. It is critical to implement an effective spare parts management system to compensate for such long repair cycle times. We developed a simulation model to study the impact of consolidating aviation component spare parts inventory management and reducing transportation cycle times.

Airline transportation systems are inherently random. However, airline planning models do not explicitly consider stochasticity in operations. Because of this, there is often a notable discrepancy between a schedules planned and actual performance. SimAir is a modular airline simulation that simulates the daily operations of a domestic airline. Its primary purpose is to evaluate plans, such as crew schedules, as well as recovery policies in a random environment. We describe the structure of SimAir, and we give future directions for the study of airline planning under uncertainty.

This paper presents an overview of a software design framework for the development of object-oriented simulations. The framework is documented using the Unified Modeling Language and is divided into packages to organize the collection of classes into important functional areas. The purpose of the framework is two-fold. First, the framework is useful in understanding the concepts and abstractions within simulation modeling and languages. Secondly, the framework can serve as the basis for the development of object-oriented simulation libraries. We illustrate the latter through a Java implementation.

The model incorporates simulation in order to include spaceport characteristics as alternative flows, processing variability, and other random events. This model will provide vehicle designers with useful understanding of the spaceport operations related to the investigated vehicle design.

The paper deals with a simulation study on a planned production plant in the brick industry. We implemented this plant in TAYLOR II. Although the boundary conditions seemed relatively simple, we had to manage a complex, non-linear system. For this reason we implemented .dynamic priority. to the main part of the system, the travelling crane. Still this sophisticated logic was not enough to guarantee good operation, because insome situations the system runs out of capacity. We then gave recommendations how to improve the situation for a perfect operation of the production system. For this purpose we finally made an analysis of the necessary investment costs against the running costs caused by system breakdown.

In many cases, a simulation model of a system is used to evaluate alternative configurations of that system, with the goal of finding the configuration which maximizes (or minimizes) the value of an objective while meeting all of the stated requirements. The CSIM18/OptQuest package automates this kind of search for the best configuration by combining a powerful simulation engine, CSIM18, and a state-of-the-art optimization package, OptQuest. This paper describes this integrated package for doing optimization and simulation. The paper concludes with two examples: finding the best configuration for a jobshop, and finding the best configuration for a web server.

Simulation professionals need to see themselves first as systems analysts, i.e., problem solvers, rather than just simulation users. As the networked digital economy develops, systems will become more complex, creating a robust market for experienced systems analysts who use simulation to solve operational problems and manage these complex systems. Physicians solve problems involving a complex biological system, i.e., the human body. The medical education system in the United States is examined and proposed as a model for an education structure for professional systems analysts. The objectives and requirements of simulation education are examined and a curriculum structure is proposed. It is also argued that certifying exams would do much to promote the profession and improve the educational environment.

This paper deals with the issue of how one can teach simulation in the most time-efficient way. We first distinguish between different types of student as regards their background and future needs. We next look at reasons for studying simulation at a business school. Next we compare animation oriented simulators with simulation languages. We then study a list of desirable criteria for simulation software, in particular simulation languages, that should be used in education. We finally answer the question if there is any system that fulfills all of these criteria.

The distribution warehouse is located between manufacturers and customers. Storage facilities are designed around four primary functions: holding, consolidation, break-bulk, and mixing. In addition, materials handling within a storage-handling system reduces to three primary activities: loading and unloading, movement to and from storage, and order filling. Generally, it is more difficult to build a simulation model for a non-automated warehouse than for AS/RS, because materials handling is much more complicated. In this study, a procedure to build simulation models for move store activities of complicated and non-automated distribution warehouses is proposed. The simulation model here is designed to execute together with the program for generating parameters of materials handling.

P.1971-1977.
The UNOS Kidney Allocation Model (UKAM) is a software tool for the simulation and analysis of national cadaveric kidney and kidney-pancreas allocation policies for transplantation. UKAM is modular and is designed to enable easy updating of the various components as new data become available. UKAM.s flexibility gives the user the ability to create and evaluate an almost infinite number of detailed allocation policies. This will enable the United Network for Organ Sharing (UNOS) to make decisions based on quantitative data when considering changes in organ allocation policies.

This paper presents some innovations for overcoming shortcomings in the current state-of-the-art for the hierarchy-of-models approach to modeling aggregated force attrition in ground-combat models. The basic concept of such an approach for modeling large-scale system behavior is presented, together with the theoretical underpinnings for modeling attrition in large-scale ground combat.

This paper describes the development of a traffic-modeling tool as an Arena template and two applications of it: one to evaluate alternative designs for the road network on the premises of Amsterdam Airport Schiphol and one to assess the effects of traffic signaling on a junction. The tool uses discrete event simulation, very suited for modeling traffic in areas where there are a lot of interactions other than car following. Generation of the O/D matrix was done automatically by a custom-made application.

We present a mapping of Best Practices from the field of software engineering to the practice of discrete event simulation model construction. There are obvious parallels between the two activities. We therefore hypothesize there should be opportunities to improve the model construction process by taking advantage of these parallels. This research extends the prior work (Withers 1993) that provided a structured definition of the modeling process.

In this paper, we propose a hybrid approach which is a specific problem solving procedure combining analytic and simulation methods to solve production-distribution problems in supply chains. The machine capacity and distribution capacity constraints in the analytic model are considered as stochastic factors and are adjusted by the proposed specific process according to the results from an independently developed simulation model which includes general production-distribution characteristics.

The modelling and simulation theory is considered and its support for constructing distributed simulations. Formal representation of simulation models can contribute to a number of aspects in the modeling and simulation enterprise. Separation of models from simulation execution engines is a prerequisite transferring model among phases of a project as well as from project to project. The Discrete Event System Specification formalism, drawing on its system theoretic basis, provides a number of important properties such as hierarchical, modular composition, universality and uniqueness that can support development of simulation models and environments their development.
