Inventory control in a multi-supplier system
An enterprise network is analyzed from the viewpoint of an end-product manufacturer who receives customer orders and organises his production and supply policy so as to minimize the sum of his average holding cost and average stock-out cost. For each main component to be ordered, the producer has several possible suppliers. The arrivals of customers’ orders are random and delivery times from su...
متن کاملModeling Multi-Echelon Multi-Supplier Repairable Inventory Systems with Backorders
This paper considers an inventory system responsible for repairable equipments located at several operational sites, each in different area. When a failure occurs at the operational site, spare parts are required. We analyze a multiple-supplier inventory system that includes an internal repair shop that offers several modes of repair with different repair times and an external supplier of spare...
متن کاملInfluence of product return lead-time on inventory control
We consider a production-inventory system with capacity constraint and item returns correlated to demand. The system is modelled by an M/M/1 make-to-stock queue with lost sales. A satisfied demand incurs an item return with a certain probability, after an exponentially distributed return lead-time. We distinguish two cases: When the number of items to be returned is observable and when it is no...
متن کاملOptimal Stochastic Control in Continuous Time with Wiener Processes: General Results and Applications to Optimal Wildlife Management
We present a stochastic optimal control approach to wildlife management. The objective value is the present value of hunting and meat, reduced by the present value of the costs of plant damages and traffic accidents caused by the wildlife population. First, general optimal control functions and value functions are derived. Then, numerically specified optimal control functions and value func...
متن کاملRobust inventory control under demand and lead time uncertainty
In this paper a general methodology is proposed based on robust optimization for an inventory control problem subject to uncertain demands and uncertain lead times. Several lead time uncertainty sets are proposed based on the budget uncertainty set, and a set based on the central limit theorem (CLT). Robust optimization models are developed for a periodic review, finite horizon inventory contro...
