A Heuristic Approach for the Integrated Production and Distribution Problem

چکیده
Production distribution planning is the most important part in supply chain management. In this paper, An NP-hard production-distribution problem for one product over a multi-period horizon is investigated. The aim is to minimize the sum of three costs: production setups, inventories and distribution. The objective is to determine, for each period, the amount produced, the inventory levels and the delivery trips. To solve this difficult problem, we propose a bi-phase approach based on a Variable Neighbourhood Search (VNS). This heuristic is tested on 90 randomly generated instances in the literature, with 20 periods and 50, 100, 200 customers. Computational results are presented, that show that our approach is competitive and even outperforms existing solution procedures proposed in the literature.

متن کاملA new approach in graph- based integrated production and distribution scheduling for perishable products
This study is concerned with how the quality of perishable products can be improved by shortening the time interval between production and distribution. As special types of food such as dairy products decay fast, the integration of production and distribution scheduling (IPDS) is investigated. An integrated scheduling of both processes improves the performance and costs because the separated sc...

A Mixed Integer Programming is proposed for the problem. In addition, a hybrid meta-heuristic...
متن کاملProbabilistic Integrated Planning of Primary and Secondary Distribution Networks based on a Hybrid Heuristic and GA Approach
The integrated planning of distribution system reveals a complex and non-linear problem being integrated with integer and discontinues variables. Due to these technical and modeling complexities, many researchers tend to optimize the primary and secondary distribution networks individually which depreciates the accuracy of the results. Accordingly, the integrated planning of these networks is p...
