STOCK RATIONING IN A MULTI-CLASS MAKE-TO-STOCK QUEUE WITH INFORMATION ON THE PRODUCTION STATUS August 2006

چکیده
We consider a single-item make-to-stock production system. The item is demanded by several classes of customers arriving according to Poisson processes with different backorder costs. Item processing times have an Erlang distribution. This allows us model the information on the production status in a tractable way and to investigate the impact of processing time variability. Using a Markov Decision Process formulation, we show some structural properties of the optimal stock allocation policy. We also present a heuristic and discuss how to optimize its parameters. We show by numerical experiments the effectiveness of this heuristic policy. In addition, we study the influence of processing time variability on the performance of the system.

Stock Rationing in a Multi-class Make-to-stock Queue with Information on the Production Status
We consider a single-item make-to-stock production system. The item is demanded by several classes of customers with different backorder costs. The item can also satisfy demands from a salvage market without a backorder cost. Item processing times have an Erlang distribution. This allows us to model the information on the production status in a tractable way. We fully characterize the optimal s...
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 کاملMulti-site production planning in hybrid make-to-stock/make-to-order production environment
Today competitive environment has enforced practitioners and researchers to pay great attention to issues enhancing both production and marketing competitiveness. To do so, it has been obligatory for the firms to consider production side activities while customer requirements are on the other side of competition. In this regard, hybrid make-to-stock (MTS)/make-to-order (MTO) production systems ...

[1] Corresponding author e-mail: [email protected] [1] Corresponding author e-mail: [email protected] Lot-sizing problems (LSPs) belong to the class of production planning problems in which the availability quantities of the production plan are always considered as a decision variable. This paper aims at developing a new mathematical model for the multi-level ca...
