This study examines the operational and scheduling aspects of the Just-In-Time (JIT) philosophy. It briefly traces the historical origins of JIT and discusses the present and projected future impacts of this philosophy in the manufacturing, transportation and communication domains. The results of questionnaires designed and administered to elicit information on field deployment practices of JIT and on intermodalism as it impacts JIT are presented. Industry JIT success briefs and impacts in the industry are reviewed. Reports are provided of findings during on-site visits to six JIT organizations. The broad spectrum of products and services ("JIT Support Products") that leverage the probability of a successful JIT program implementation is discussed. A simulation model of a manufacturing system that is supplied raw materials by JIT carriers was successfully developed and tested using the SIMFACTORY simulator. Simulation results are analyzed and presented based on a full factorial design experiment. The Markovian reliability model formulated specifies time dependent transportation vehicle reliabilities for different states of operation of a JIT vehicle. Both the reliability and simulation models developed could be used for resource scheduling and as an information tool for providing broad guidelines for resource allocations at intermodal interfaces operated on a JIT basis.
