Because the risk factors cannot be accurately measured it is very difficult to evaluate the risk of supply chain. By introducing hesitancy degree into the risk evaluation process, an intuitionistic fuzzy model is developed to describe the problem. With this model, an algorithm is proposed to evaluate the risk of supply chain. Example shows that the proposed method is superior to the existing ones...
Supply chain, as an effective mode participating in the intense business competition, has been accepted by scores of enterprises, but there still exists great risks in supply chain, because of the characteristics of its special chain structure. This paper investigates the sources of supply chain risk, and the factors of supply chain risk assessment. Based on this, a fuzzy assessment model used to...
One of the initial researches on supply risk criteria in a supply chain is that of Kraljic. This research gives a method to classify supplied items into four categories in terms of risk and price share and presents a set of strategies to supply the items of each category. Although the addressed research gives some criteria to measure supply risk but it is not applicable in each industry due to lack...
Supply chain is a complicated, open system, for the constant development, and fierce degree of market competition of the society increase day by day, the discrimination and management of risk of Supply chain are more essential. Kinds of risk factors of Supply chain are analyzed in the text, according to the influence degree of each risk factor, a method combined BP neural network and fuzzy evaluation...
The reverse logistics is necessary for retailing to reinforce competitive advantage, increase customer value and improve its whole performance of supply chain. The retailing reverse logistic is either a premise of effective decision or important method for enterprise to decrease operating risk and improve service. In the paper, first, the theoretical triangular fuzzy number is put forward. And the...
Supply chain system is a dynamic network system with fuzzy edge, and how to assess the risks of this system has become the bottleneck of enterprises management. In the light of the influence diagram theory, this paper builds a risk assessment model of supply chain from the topology layer and function layer. The model graphically describes the elements of risk assessment process and takes into account...
