This paper describes an effort that involved development of a simulation model for evaluating the business processes and inventory control parameters of a logistics and distribution supply chain. A generic simulation tool, rather than a supply chain simulator, was developed for meeting customized needs of the effort. The paper describes the approaches used(More)
This paper presents a case study of using simulation for analyzing the impact of proposed changes in the supply chain processes for a large logistics operation. The major changes explored include business process changes, and use of new supply chain software. The results of the analysis indicate that the changes in forecast accuracy provide much larger(More)
2004 brought a landmark event in the changes to regulations governing hours of service for truck drivers. This paper describes an effort utilizing modeling and simulation for evaluating the impact of the new 2004 Hours of Service (HOS) rules in scheduling and dispatching one of the largest random over-the-road (OTR) trucking fleets in North America. The(More)
In the North American energy market, natural gas (NG) prices have been gradually decreasing during the past several years, primarily due to advances in shale gas extraction techniques. The availability of cheaper NG, while seen as an attractive short-term fuel switching option, is viewed with caution by most cement plants due to long-term procurement(More)
