The two management set parameters which determine the performance of a material requirements planning (MRP) system are the lead time and the safety stock. The appropriate values of these parameters are influenced by the accuracy of forecasts over the lead time, the variability of processing time...

In this paper we consider a class of job shops with a dispatch area and a machine shop, where operational controls are exercised at the dispatch area as well as at the machine shop. For such dynamic job shops with these two levels of control, there are three categories of models. They are (1)...

In most integrated works, ingots are used as an intermediate form during the production of steel. These ingots, produced by pouring molten steel into molds, are too large to be used as input for the finishing mills which produce steel products. Hence, more manageable forms (blooms, billets and...

This paper reviews recent work on the development of analytical models of Flexible Manufacturing Systems (FMSs). The contributions of each of the groups concerned with model development are summarized and an assessment is made of the strengths and weaknesses of its modelling approach. A number...

Most of the traditional models in production and inventory control ignore the financial states of an organization and can lead to infeasible practices in real systems. This paper is the first attempt to incorporate asset-based financing into production decisions. Instead of setting a known,...

Process reengineering advocates making radical changes in how processing systems are structured, such as moving away from systems that use the principles of division of labor and division of management. Using formal system models from queueing theory, this paper explores the conditions under...
