IDENTIFYING AND PRIORITIZING COST REDUCTION SOLUTIONS IN THE SUPPLY CHAIN BY INTEGRATING VALUE ENGINEERING AND GRAY MULTI-CRITERIA DECISION-MAKING

Value engineering is an appropriate policy for creating and improving value, which reduces unnecessary costs and maintains core functionality. Despite the mentioned benefits, this approach has so far received little attention in the area of supply chain management. Although this approach is highly structured, limitations such as overemphasizing the cost criterion and failure to meet other criteria, utilizing team members’ votes to rank solutions, ignoring inherent uncertainty and ultimately disagreement between value engineering team members have reduced the effectiveness of this approach. The present study aims to provide a coherent framework for utilizing a value engineering approach to supply chain cost management and overcome the aforementioned limitations by utilizing gray multi-criteria decision-making. In this regard, in the first phase, the initial list of improvement solutions is determined, the criteria extracted from the literature are localized using value engineering team members’ opinion. These criteria are weighted using the gray stepwise weight assessment ratio analysis (SWARA-Gray) method. Then, the score of each solution is calculated by the value engineering team based on the list of criteria as a gray number. The scores are aggregated using the gray evaluation based on distance from average solution (EDAS-Gray) method, and the solutions are prioritized. Finally, the application of the proposed framework is investigated in a real case study in a power plant in Iran. The results of the research show that the final rankings of the solutions rarely changed for different methods; so the model used in this study has acceptable stability.

Supply Chain Controllable Costs Management and Strategy Analysis

With the globalization of economic development, the competition between the enterprises becomes more intense. If you want to have a survival advantage in the fierce competition, you must find ways to achieve high efficiency and low cost strategy. But simply to raise revenue or simply to cut costs can't satisfy the requirement of enterprise survival and development. Therefore, to increase income and reduce cost, the combination of both, become the first background of enterprise development. The concept of supply chain cost management meets the requirement of this strategy. Diversity of the concept of supply chain, and constant adjustment along with the market determines the supply chain cost management is comprehensive and complicated system engineering.

Study on Green Intelligent Supply Chain Cost Management in Manufacturing Engineering

Cost management is the key to promoting the green intelligent supply chain development of the enterprise. This study analyzed the necessity of the green intelligent supply chain cost management and the cost structure of green intelligent supply chain. Meanwhile a profound research on the direct and indirect cost management, transactional and coordinated cost management, waste disposal cost management and the realization cost management of green intelligent supply chain is done. The origenal of this paper is the realization and satisfaction of the cost management in the whole process of the green intelligent supply chain inside and outside the enterprise.
