Supply Chain Scheduling

Consider for example a production unit supplied by one or more raw material [5]. An order cannot be released before aU the required has arrived. That is an order j has an earliest possible starting time (release date rj), a committed shipping date dj, and a priority factor or weight Wj. Every time a machine switches over from one type of item to another, a setup may be required and a setup cost may be incurred. The supply chain model here is composed of a model within each production unit depending on its structure, job shop, flowshop, single machine, etc., and an objective function that links the two models. The objective to be minimized may include the minimization of the total setup times and the total tardiness 7 denoted as, [Pg.38]

More general supply chain stractures are studied in the literature. An example of such structure is shown in Fig. 3.10. A model for a similar supply chain structure will given next. [Pg.38]

Finally, an interesting trend in supply-chain management is improving business practices by providing capabilities to improve service for customers. One such concept is capability to promise. The idea is not just to ensure that the product is available, but that the supply chain is capable of delivering the product. This involves, for instance, capability to rapidly change the schedule to accommodate the customer order and interact with the active plant schedule. Such a system was developed at Celanese Fibers, which is integrated with a Customer Order System and enabled via a Web browser. [Pg.89]

Companies who to date have decided in favor of the quant-based combinatorial optimization approach, are collectively characterized by a complex and multi-step supply chain whose scheduling requires the consideration of multiple constraints. By nature of their production processes, many of these companies come from the chemical or pharmaceutical industry. [Pg.63]
