A ̄exible manufacturing system (FMS) is highly capital-intensive and FMS users are concerned with achieving high system utilization. The production planning function for setting up an FMS prior to production should be developed in order to make the most of the potential bene®ts of FMSs. We consider two production planning problems of grouping and loading a ̄exible ̄ow system, which is an important...

Internet routing is based on implicit trust assumptions. Given the critical importance of the Internet and the increasing security threats, such simple trust relationships are no longer sufficient. Over the past decade, significant research has been devoted to securing the Internet routing system. The Internet Engineering Task Force (IETF) is well along in the process of standardizing routing s...

in the case of hazardous materials management, selected routes for carrying hazardous materials (i.e.,hazmat) have significant effects on locating hazmat distribution centers. since, risk and cost are usuallyconsidered as two main attributes to determine the best routes, optimized locations are sequentially outlineddepending on selected routes. in the present paper, two different approaches of ...

Purpose This study focuses on a specific method of meat production that involves carcass purchase and by packing facilities with novel two-stage model simultaneously considers location-routing inventory-production operating decisions. The considered problem aims to reduce variable fixed transportation costs, inventory holding cost the opening cold storage facilities. Design/methodology/approach...

periodic vehicle routing problem focuses on establishing a plan of visits to clients over a given time horizon so as to satisfy some service level while optimizing the routes used in each time period. this paper presents a new effective heuristic algorithm based on data mining tools for periodic vehicle routing problem (pvrp). the related results of proposed algorithm are compared with the resu...

Global competition and changing customer requirements are putting major challenges in the production planning and control systems of manufacturing enterprises. Production planning and control requires robust methods able to cope with demand variability, processing times variability, routing sequences, resource availability, etc., between other sources of variation. Production planning and contr...

Avoiding deadlock is essential in the operation of highly automated manufacturing systems. Many of these systems support sufficient redundancy to permit flexible part routing. Although flexible routing improves the inherent operational flexibility of these systems, it also requires more highly sophisticated supervisory control techniques. The objective of this work is to characterize the deadlo...

An integrated supply chain operational planning system is a tool that is used to jointly optimize several planning decisions by capturing the additional bene ts of coordination between sequential activities in the chain. In recent years, many companies have set up an integrated planning system and achieved multi-million cost savings. The key to success is an application that is not only able to...
