A Two-Stage Production Planning Model for Perishable Products Under Uncertainty
نویسنده
چکیده
This study addresses the production planning problem for perishable products, in which the cost and shortage of products are minimized subject to a set of constraints such as warehouse space, labor working time and machine time. Using the concept of postponement, the production process for perishable products is differentiated into two phases to better utilize the resources. A two-stage stochastic programming with recourse model is developed to determine the production loading plan with uncertain demand and parameters. A set of data from a toy company shows the benefits of the postponement strategy: these include lower total cost and higher utilization of resources. Comparative analysis of solutions with and without postponement strategies is performed. Key-Words: Production planning, Stochastic Programming, Modeling, Perishable

A Stochastic Programming Approach for a Multi-Site Supply Chain Planning in Textile and Apparel Industry under Demand Uncertainty
In this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. A two-stage stochastic linear programming approach is used to maximize the expected profit. Decisions such as the production amount, the inventory level of finished and semi-finished product, t...

متن کاملA Robust Model for a Dynamic Cellular Manufacturing System with Production Planning
In this paper, a robust optimization approach is proposed to design a dynamic cellular manufacturing system (DCMS) under uncertainty of processing time of products. In addition, a mathematical model considering cell formation, inter-cell design and production planning under a dynamic environment (i.e., product mix and demand are changed in each period) is presented. Therefore, reconfiguration b...
متن کاملIntegrated planning for blood platelet production: a robust optimization approach
Perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. This paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. Whole blood-derived production methods for...
