SERVICE-BASED MANUFACTURING: THE SERVICE FACTORY

Evidence suggests that factory-based service will become the next form of competition among manufacturers. If this is true, then manufacturing executives will have to obtain a clear understanding of the service capabilities of their plants and adjust their strategies accordingly. We define a set of factory-based services, information, problem solving, sales, and support, and suggest that they be considered in developing manufacturing strategy. Several propositions provide a framework for future research by linking service performance variables to conventionally accepted manufacturing performance variables.     

LOGISTICS MANAGEMENT SYSTEM: AN ADVANCED DECISION SUPPORT SYSTEM FOR THE FOURTH DECISION TIER DISPATCH OR SHORT-INTERVAL SCHEDULING

The Logistics Management System (LMS) is a real-time transaction-based system combining decision technologies from AI, MS/OR, and decision support system that serves very successfully as a dispatcher or short-interval scheduler by monitoring and controlling the manufacturing flow of IBM's semiconductor facility near Burlington, Vermont. LMS coordinates the actions and decisions of several logically isolated participants in a serially dependent system of activities. Therefore, it balances the requirements of several goals (cycle time, output, serviceability, and inventory management) that compete for the same resource, exploits emerging opportunities on the manufacturing floor, and reduces the distortion from unplanned events. This paper provides an overview of the LMS application, the concept of interrelated decision tiers in manufacturing decision making, and the need for the dispatch decision tier to successfully reduce apparent randomness. Historically, production and operations management has ignored this decision tier. This has significantly limited our ability to make an impact on the performance of the manufacturing operation.
