Robust Optimization of Multi-Period Production Planning Under Demand Uncertainty

Optimizing decentralized production–distribution planning problem in a multi-period supply chain network under uncertainty

Decentralized supply chain management is found to be significantly relevant in today’s competitive markets. Production and distribution planning is posed as an important optimization problem in supply chain networks. Here, we propose a multi-period decentralized supply chain network model with uncertainty. The imprecision related to uncertain parameters like demand and price of the final produc...

Multi-period Mixed Production Planning with uncertain demands: Fuzzy and interval fuzzy sets approach

This paper shows a general model of a Mixed Production Planning problem with fuzzy demands. The main focus is the development of a model for Production Planning using fuzzy sets in order to use classical mathematical programming techniques to reach an optimal solution over a multiple criteria context. The classical Fuzzy Linear Programming model namely the Soft Constraints Model is used to invo...

Multi-period, Multi-product, Aggregate Production Planning under demand uncertainty by considering Wastage Cost and Incentives

Aggregate production planning (APP) involves the simultaneous determination of company’s production, inventory and employment levels which fall between the broad decisions of long range planning and detailed short range planning. A mathematical model is formulated to investigate the optimal decision on each planning period. The goal is to minimize the total relevant costs considering time varyi...

Optimal Crashing of Multi Period-Multi Product Production Planning Problems

To save overhead and penalty costs, in many cases of Multi-Period Multi-Product (MPMP) planning systems, reducing the completion time is highly desirable. Therefore, in this paper we study this problem. We propose an approach in which a MPMP problem is converted into a project management network. Then, considering network concepts and properties, a multi stage novel mathematical model is propos...
