An analysis of supply chain decisions with asymmetrical retailers : effects of disruptions and static service cost on coordination mechanism

Kebing Chen, Lei Yang, Yanxia Liu (2012)

RAIRO - Operations Research - Recherche Opérationnelle

The risk of demand or production cost disruption is one of the challenging problems in the supply chain management. This paper explores a generalized supply chain game model incorporating the possible disruptions. We find that a nonlinear Grove wholesale price scheme can fully coordinate such a supply chain even when both market demand and production cost are disrupted. The nonlinear Grove wholesale price scheme has three sides to coordinate the decision behavior of the players. One is that the...

An approach to solve a fuzzy bi-objective multi-index fixed charge transportation problem

Maroua Hakim, Rachid Zitouni (2024)

Kybernetika

In this paper, we propose a novel approach for solving a fuzzy bi-objective multi-index fixed-charge transportation problem where the aim is to minimize two objectives: the total transportation cost and transportation time. The parameters of the problem, such as fixed cost, variable cost, and transportation time are represented as fuzzy numbers. To extract crisp values from these parameters, a linear ranking function is used. The proposed approach initially separates the main problem into sub-problems....
