A Markov Model to Determine Optimal Equipment Adjustment in Multi-stage Production Systems Considering Variable Cost
Our aim is to maximize expected profit per item of a multi-stage production system by determining best adjustment points of the equipments used based on technical product specifications defined by designer. In this system, the quality characteristics of items produced should be within lower and higher tolerance limits. When a quality characteristic of an item either falls beneath the lower li...
متن کاملOptimization of two-stage production/inventory systems under order base stock policy with advance demand information
It is important to share demand information among the members in supply chains. In recent years, production and inventory systems with advance demand information (ADI) have been discussed, where advance demand information means the information of demand which the decision maker obtains before the corresponding actual demand arrives. Appropriate production and inventory control using demand info...
متن کاملOptimal multi-stage logistic and inventory policies with production bottleneck in a serial supply chain
Bottleneck appears in a serial supply chain if the minimum production rate at all stages is smaller than the demand rate. Operation manager must focus on keeping the bottleneck stage fully utilized and forcing the other stages to produce in synch with the bottleneck. This study applies the lot size division method, the recursive tightening method, and the drum-buffer-rope strategy. A pull and r...
متن کاملA Ratio-Based Efficiency Measurement for Ranking Multi-Stage Production Systems in DEA
Conventional data envelopment analysis (DEA) models are used to measure efficiency score of production systems when they are considered as black boxes and their internal relationship is ignored. This paper deals with a common special case of network systems which is called multi-stage production system and can be generalized to many organizations. A multi stage production system has some stages...
متن کاملA simulation analysis of controlling rules for flexible pull systems
The pull-type manufacturing system is known for its need for a frozen schedule, balanced workload and inability to handle fluctuations in demand. But today’s research and development are addressing the ways to handle a pull-type system to accommodate greater fluctuations. One approach is to design the system with greater routing flexibility in that flexible machines and multiple part types are ...
