Caterpillar developed the dealers' parts inventory sharing (DPIS) and returns programs to help dealers cope with excess inventory. However, historical data show that the current returns policy has been very costly to Caterpillar due to the distribution strategy. In this project, we develop alternative returns policies and propose to use simulation to analyze the cost structure of the alternative policies, develop cost sharing schemes, and compare performance with the current policy under different scenarios. It is shown that the simulation tool we developed provides industry managers with a test ground for new returns strategies and the output analysis presents guidelines to set parameters when using the new strategies to manage returns distribution.","PeriodicalId":275394,"journal":{"name":"Proceeding of the 2001 Winter Simulation Conference (Cat.

Dynamic objects (also called temporary entities or transactions) move physically or logically from one model component to another and represent entities such as aircraft, data packets, passengers, and vehicles. Accurate flow (movement) of thousands or millions of dynamic objects within a complex simulation model significantly affects the overall model validity. We present a new automated testing technique for assessing the accuracy of dynamic object flows. The permissible sequence and precedence of dynamic object flows are specified using the context-free grammar formalism. The specification accuracy is assessed using a variety of verification and validation techniques. The executable model is instrumented and dynamic object flow trace data is generated. The trace data is automatically compared with respect to the specification and each dynamic object movement traced during model execution is automatically verified.","PeriodicalId":275394,"journal":{"name":"Proceeding of the 2001 Winter Simulation Conference (Cat.

This paper provides an update to the approach, describing the substantial progress made in developing a modelling tool set called the Rapid Modelling System (RMS) to take advantage of the original concept. The paper describes the problems encountered during the development and the methods employed to overcome them, whilst keeping to the overall aim of providing a generic structure to the RMS. The current functionality is described including the ability to use propagation data and target strength values for sensor performance. An illustrative example of a tactical set of procedures is described and a worked example is provided showing how the RMS allows variations to be made in a controlled and repeatable manner.

What is unique over other optimistic systems is that reverse computation as opposed to state-saving is used to support the rollback mechanism. In this model, a hierarchy of view storage servers are connected to an array of client-side local disks. The term view refers to the output or result of a query made on the part of an application that is executing on a client machine. These queries can to be arbitrarily complex and done using SQL. In our performance study of this model, we find that speedups range from 1.5 to over 5 on 4 processors. Super-linear speedups are attributed to a slow memory subsystem and the increased availability of level-1 and level-2 cache when moving to a larger number of processors.","PeriodicalId":275394,"journal":{"name":"Proceeding of the 2001 Winter Simulation Conference (Cat.

This is because it usually takes a longer time to generate a result from the simulation, and the simulation model of a manufacturing system is usually too sophisticated and time-consuming to use as an interactive tool by the manufacturing/production engineer. A CAMS reduces this complication by encapsulating the 'complicated-logic' and automating the 'tedious data-acquisition' with a more user-friendly interface like a spreadsheet or database input form. The paper describes how CAMS can automatically generate a simulation model; specifically, techniques and issues to structure the model to hide those tasks, so that it is a user-friendly interactive decision support with minimal amount of automation code. The paper concludes with a capacity analysis example from the real industry.","PeriodicalId":275394,"journal":{"name":"Proceeding of the 2001 Winter Simulation Conference (Cat.

It can also be used to find out how to best use available resources to sustain a military force in a wide variety of scenarios. The \"system\" in TLoaDS refers to its modular architecture and that it is more that just a simulation. It is a suite of analytical study tools.

The software developed is modular and designed to work in heterogeneous environments. The method is expected to reduce the modeling and maintenance effort considerably when modeling entire factories.

In the bottleneck area of photolithography the steppers form several different subgroups. These subgroups differ, for example, in the size of the masks that have to be used for processing lots on the steppers of a single group. During lot release it is necessary to distribute the lots over the different stepper groups in such a way that global targets like cycle time minimization, the maximization of the number of finished lots and due date performance are inside a certain range. A simulation model of a wafer fab is given that models the, photolithography area in a detailed manner. By means of this simulation model it is possible to decide at release time on which stepper subgroup processing of the lots of a certain product is favorable.","PeriodicalId":275394,"journal":{"name":"Proceeding of the 2001 Winter Simulation Conference (Cat.

Simultaneously, the strategic importance of delivery accuracy, short delivery times, and production flexibility is increasing with the highly fluctuating demand and short product life cycles of end products. New principles, that minimize throughput time while guaranteeing excellent customer service and adequate capacity utilization, are needed for production planning and control. Simulation is needed in order to develop the new principles and test their superiority. This paper presents an ongoing simulation project that aims at developing the production planning and control of a PWB manufacturer. In the project, a discrete event simulation model is built of a pilot case factory. The model is used for comparing the effect of scheduling, queuing rules, buffer policies, and lot sizes on customer service and cost efficiency.","PeriodicalId":275394,"journal":{"name":"Proceeding of the 2001 Winter Simulation Conference (Cat.
