Today, interest about the recovery of used products and materials is on increasing. Therefore, reverse logistics will become power and great potential for winning consumers in more competitive contexts in the future. This paper considers the multistage reverse Logistics Network Problem (mrLNP) with minimizing the total of costs to reverse logistics shipping cost. We will demonstrate the mrLNP m...

We are introducing a new design goal called area priority for finding optimal sensor node distribution. Environment that wireless sensor network (WSN) will be placed is divided into parts and priorities are attached to these parts. Priorities make the deployment problem adaptable to non-homogeneous environments such as forests having regions that have different importance levels. Various tree/a...

under an intensive competitive environment, the construction industry is facing pressure to meet the higher customer expectations under a tighter budget. on the other hand, construction is one of the main sectors generating greenhouse gases. according to published statistics, construction industry is one of the most important resources of greenhouse emissions in the world. therefore, based on t...

Logistic network design is one of the most important strategic decisions in supply chain management that has recently attracted the attention of many researchers. Transportation network design is then one of the most important fields of logistic network. This study is concerned with designing a multi-stage and multi-product logistic network. At first, a mixed integer nonlinear programming model...
