Through the analysis of Travelling Salesman Problem with Pickup and Delivery (TSPD) in the related research, two kinds of logistics systems including whole logistics system and partial logistics system under one-to-many logistic network are considered. And mathematical model is set up, then, nested cost optimization model is set up in order to meet the constraint condition of nested order cycle...

Advanced integration of logistics systems has been promoted for competitiveness and sustainability. Interconnection transport operations increases complexity at a network level, which reduces the predictability response system to disruptions. However, our understanding behavior such is still limited. In particular, topology network, changes as are integrated, an important factor that affects pe...

At present, China's automobile logistics cost accounts for more than 20% of the production of motor vehicles. Therefore, lowering logistics cost by seeking its best path is an effective way to lower the cost of automobile manufacturing. This paper combines the Graph Theory and the genetic algorithm to research the optimizing problem of the lines of logistics distribution. Traffic flow data unde...

The design of closed-loop supply chain networks has attracted increasing attention in recent decades with environmental concerns and commercial factors. Due to the rapid growth of knowledge and technology, the complexity of the supply chain operations is increasing daily and organizations are faced with numerous challenges and risks in their management. Most organizations with limited resources...

The present study introduced a novel hierarchical hub set covering problem with capacity constraints. This study showed the significance of fixed charge costs for locating facilities, assigning hub links and designing a productivity network. The proposed model employs mixed integer programming to locate facilities and establish links between nodes according to the travel time between an origin-...

This research study presents a comprehensive model for selection of decisive criteria to develop and integrate a fourth-party logistics concept in humanitarian logistics sector. The model is based on applying an analytic network process for determination of final criteria selection for a fourth-party logistics solution. The analytic network process is used to solve complex multiple qualitative ...

Activities in reverse logistics activities are extensively practiced by computer hardware industries. One of the important problems faced by the top management in the computer hardware industries is the evaluation of various alternatives for end-of-life (EOL) computers. Analytic network process (ANP) based decision model presented in this paper structures the problem related to options in rever...
