Facing harsh competition in global marketplaces, management must construct the best possible supply chains to meet client requirements of quality, timely, and diverse products. To accelerate the fabrication rate can help shorten the length of the refilling cycle, and the reworking of repairable...

Traditionally, mathematical optimization methods have been applied in manufacturing industries where production scheduling is one of the most important problems and is being actively researched. Extant studies assume that processing times are known or follow a simple distribution. However, the...

In transportation via containers, unbalanced movement of loaded containers forces shipping companies to reposition empty containers. This study addresses the problem of empty container repositioning (ECR) in the distribution network of a European logistics company, where some restrictions impose...

This article applies game theory in the company under study, in order to optimize the competitive strategy with respect to its main competitor in the bicycle and motorcycle market. Once the problem is defined, the zero-sum matrix between the competitors is established, then the model is...

Minimum-cost spanning tree problems are well-known problems in the operations research literature. Some agents, located at different geographical places, want a service provided by a common supplier. Agents will be served through costly connections. Some part of the literature has focused,...
