Showing 2 results for Green Supply Chain

Abstract
A fundamental problem is the use of DEA in multistep or multilevel processes such as supply chain, lack of attention to processes’ internal communications in a way that the recent studies on DEA in the context of serial processes have focused on closed systems that the outputs of one level become the inputs of the next level and none of the inputs enter the mediator process. The present study aimed to examine the general dimensions of an open multilevel process. Here, some of the data such as inputs and outputs are supposed to leave the system while other outputs turn into the inputs of the next level. The new inputs can enter the next level as well. We expand this mode for network structures. The overall performance of such a structure is considered as a weighted average of sectors’ performance or distinct steps. Therefore, this suggested model in this study, not only provides the possibility to evaluate the performance of the entire network, but creates the performance analysis for each of the sub-processes. On the other hand, considering the data with undesirable structure leads to more correct performance estimation. In the real world, all productive processes do not comprise desirable factors. Therefore, presenting a structure that is capable of taking into account the undesirable structure is of crucial importance. In this study, a new model in the DEA by network structure is offered that can analyze the performance considering undesirable factors.

Abstract
The main aim of the study is to examine the influence of both external and internal actors on green supply chain management (GSCM) practices. By the way, this paper is to provide a first-hand understanding about the procedures taken by Turkish business firms and their logistics providers and supply chain business firms to operate in an environmental friendly supply chain. The result of this research is very important to promote performance of Turkish business relations in green perspectives. To find the right answers, comprehensive questionnaire forms were designed. We collect data from 2014 May to 2015 July through the Turkish companies. More than 180 companies have contributed in this great research. We analyzed data by statistical methods. One of the important results is the third party logistics service providers influence firms have a proactive green behavior.
