Major Electronics Manufacturer Redesigns Logistics Supply Chain, Saves Over $50 Million
Simulation of "as-is" service and repair operations led to study of five "to-be" alternatives to determine best recommendation for change. Resulting changes to supply chain design lowered costs while maintaining high customer service levels. Read more >> |
Chemical Plant Simulation Eliminates the Need for Additional Capital Investment
The engineers at a Gulf Coast chemical facility eneded to test expansion plans for a production line consisting of many production units whose products are intermediates used in making polyurethanes. The design of the major expansion had been completed, but it had not been verified with regard to storage tanks and shipping capacities. Read more >> |

A Comparison of Scheduling Approaches for a Make-to-Order Electronics Manufacturer
Susan K. Heath and Douglas J. Morrice
In this paper, we compare two scheduling procedures designed to minimize setup costs for a make-to-order electronics manufacturing. While setup costs are important, quick response is highly valued by the manufacturer’s customers and customer service is negatively impacted when jobs spend too much time in the system.

A Simulation Approach to the Evaluation of Operational Costs and Performance in Liner Shipping Operations
Aldo A. McLean and William E. Biles
This paper presents a simulation model of the operation of a liner shipping network that considers multiple service routes and schedules. The objective is to evaluate the operational costs and performance associated with liner shipping, as well as the impact of individual service schedules on the overall system. Read more >> |
Determination of Operating Policies for a Barge Transportation System Through Simulation and Optimization Modeling
Nicholas P. Anderson and Gerald W. Evans
This paper presents a simulation model of a barge transportation system for petroleum delivery within an inland waterway. The simulation is employed as an evaluation model within a decision support system that also includes a criterion model, represented as a decision maker's utility function, and an optimization procedure that employs scatter search.

An Object-Oriented Programming Approach for a GIS Data-Driven Simulation Model of Traffic on an Inland Waterway
Daniel Sasso and William E. Biles
This research proposes the integration of a Geographic Information System (GIS) with the Arena Simulation software to model the transit of ocean-going vessels through the Panama Canal. Read more >> |
A Simulation-Based Approach for Dock Allocation in a Food Distribution Center
Balagopal Gopakumar, Sumit Koli, Krishnaswami Srihari, Suvarna Sundaram and Shengyong Wang
This research endeavor focused on the warehouse receiving process at a large food distribution center, which comprises of trucks with goods reaching the destination warehouse, unloading and finally putting away the contents to the specific aisles. Discrete event simulation was used to model the current system’s functioning and to identify operational inefficiencies which were quantified through a detailed value stream mapping exercise.

A Simulation Approach to Evaluate the Impact of Introducing RFID Technologies in a Three-Level Supply Chain
Aysegul Sarac
Nabil Absi and St´ephane Dauz`ere-P´er`es
The aim of this paper is to analyze the impacts of RFID technologies on supply chain performances, in particular to evaluate their economical impacts and to conduct ROI (Return-On-Investment) analyses. Read more >> |
Simulation-Based Optimization of a Complex Mail Transportation Network
Anna Syberfeldt, Henrik Grimm, Amos Ng, Martin Andersson and Ingemar Karlsson
The Swedish Postal Services receives and distributes over 22 million pieces of mail every day. Mail transportation takes place overnight by airplanes, trains, trucks, and cars in a transportation network comprising a huge number of possible routes. For testing and analysis of different transport solutions, a discrete-event simulation model of the transportation network has been developed. Read more >> |
Using Empirical Demand Data and Common Random Numbers in an Agent-Based Simulation of a Distribution Network
William J. Sawaya III
Agent-based simulation provides a methodology to investigate complex systems behavior, such as supply chains, while incorporating many empirical elements relative to both systems structure and agent behavior. While there is a significant amount of simulation and analytical research investigating the impact of information sharing in supply chains, few studies have used empirical demand for the model.

Module-based Modeling of Production-Distribution Systems Considering Shipment Consolidation
Xiaohua Wang and Soemon Takakuwa
One of the most important aspects affecting the performance of a supply chain has been the management of inventories which is complex because demand at the upstream stage is dependent on an order from the downstream stage. Read more >> |
