in this paper, a new model is proposed for the integrated logistics network designing problem. in many research papers in this area, it is assumed that there is only one option for the capacity of each facility in the network. however, this is not a realistic assumption because generally there may be many possible options for the capacity of the facility that is being established. usually the c...

With the development of China’s express delivery industry, number packaging has proliferated, leading to many problems such as environmental pollution and resource waste. In this paper, process reverse logistics network design for recycling is given an example in M region, a four-level containing primary nodes, centers, processing terminals established. A candidate node selection model based on...

As nowadays’ forward logistics of automobile industry have been developed in a good stage, according to various car manufacturers; third-party logistics companies are more concerned about the car forward logistics. However, with the mature of automotive consumer market competition, innovation and the rise of global environmental awareness, the car reverse logistics must be given due attention a...

In this paper we define and compare Reverse Logistics definitions. We start by giving an understanding framework of Reverse Logistics: the why-what-how. By this means, we put in context the driving forces for Reverse Logistics, a typology of return reasons, a classification of products, processes and actors. In addition we provide a decision framework for Reverse Logistics and we present it acc...

Due to the significant growth in the demand for logistics services and the ongoing trend towards the outsourcing of logistics activities, logistics service providers have concurrently gained a significant profit-making opportunity and faced the unprecedented challenge of surviving in the midst of increasingly fierce market competition. This research thus aims to propose routing strategies that ...

Logistics network design is a major strategic issue due to its impact on the efficiency and responsiveness of the supply chain. This paper proposes a model for integrated logistics network design to avoid the sub-optimality caused by a separate, sequential design of forward and reverse logistics networks. First, a bi-objective mixed integer programming formulation is developed to minimize the t...
