Multi-product newsboy problem with limited capacity and outsourcing
نویسندگان
چکیده
This paper considers a multi-product newsboy system that produces multiple products for fulfilling independently uncertain demands, which share the same production capacity. To deal with possible shortage of limited capacity, productions can be outsourced. We consider two outsourcing strategies: zero lead time outsourcing, and nonzero lead time outsourcing. The structural properties and solution procedures for the profit-maximization models are developed. Numerical results are provided for obtaining some managerial insights. 2009 Elsevier B.V.

A Hybrid Meta-Heuristic Method to Optimize Bi-Objective Single Period Newsboy Problem with Fuzzy Cost and Incremental Discount
In this paper the real-world occurrence of the multiple-product multiple-constraint single period newsboy problem with two objectives, in which there is incremental discounts on the purchasing prices, is investigated. The constraints are the warehouse capacity and the batch forms of the order placements. The first objective of this problem is to find the order quantities such that the expected ...

Optimizing the service card in multi-depot, multi-product and multi-level vehicle routing problem is one of the most important and at the same time, the most complex problems in the transportation problems contexts. Numerous exact heuristic and meta-heuristic algorithms have been developed for different vehicle routing problems. In this paper, a binary linear programming (BLP) based model for o...

Abstract : In this paper a meta-heuristic approach has been presented to solve lot-size determination problems in a complex multi-stage production planning problems with production capacity constraint. This type of problems has multiple products with sequential production processes which are manufactured in different periods to meet customer’s demand. By determining the decision variables, mac...
متن کاملA portfolio approach to multi-product newsboy problem with budget constraint
This paper investigates a portfolio approach to multi-product newsboy problem with budget constraint, in which the procurement strategy for each newsboy product is designed as portfolio contract. A portfolio contract consists of a fixed-price contract and an option contract. We model the problem as a profit-maximization model, and propose an efficient solution procedure after investigating the ...
متن کاملOptimal flexible capacity in newsboy problem under stochastic demand and lead-time
In this paper, we consider a newsvendor who is going to invest on dedicated or flexible capacity, our goal is to find the optimal investment policy to maximize total profit while the newsvendor faces uncertainty in lead time and demand simultaneously. As highlighted in literature, demand is stochastic, while lead time is constant. However, in reality lead time uncertainty decreases newsvendor's...
