Integrated Quality-Based Production-Distribution Planning in Two-Echelon Supply Chains

Abstract

The integrated production-distribution (P-D) planning has turned into one of the most essential areas in supply chain (SC) management in recent years, especially in the case of perishable products in which the quality of products can change over time. Nonetheless, so far, the suggested models have focused on the P-D stages of the chain while the delivery of high-quality products to customers is of paramount significance in the perishable SC. In the present paper, a multiobjective, mixed-integer, and nonlinear programming (MOMINLP) mathematical model was developed for integrated P-D deteriorating items in a two-echelon SC that emphasizes quality degradation. Quality is monitored and calculated as a function of temperature and time throughout the SC, and the main purpose of the model is to first increase the quality of products delivered to customers and, second, minimize the SC costs. To optimize the problem, the particle swarm optimization (PSO) approach was also incorporated into the model. The obtained model was applied to a case study in Protein Gostar Sina Company in Iran, which resulted in decreased P-D costs as well as increased customer satisfaction.

Integrated scheduling of distributed production and distribution in group manufacturing with uncertain travel time

“…However, this decentralized approach leads to inefficiency, due to the complex organizational structure and untimely information transmission in manufacturing group. Thus, they need to be considered together to improve the production efficiency and reduce the operation cost of the manufacturing group [ 3 ]. Moreover, considering the difficulty in coordinating behavior of different subsidiaries, integrated production and distribution scheduling problem is one of the most important challenges facing by the group manufacturing.…”
