Evaluation and Selection of Cement Suppliers under the Background of New and Old Driving Energy Conversion in China

Abstract

Accompanied by the concept of supply-side structural reform and conversion of new and old driving energy to create a new round of economic development in China, cement supplier evaluation and selection are increasingly crucial for concrete production plants, ensuring not only raw material supply with high quality and at a reasonable price but also sustainable and long-term cooperation with suppliers. Given the limitations of the existing approaches, this study proposes a cement supplier evaluation and selection framework based on the combination of the improved FAHP-CRITIC method and VIKOR method. We first develop a cement supplier evaluation and selection index system under the background of new and old driving energy conversion, including eight first-level indicators and twenty-one second-level indicators. The proposed model then uses triangular fuzzy numbers AHP (TFN-AHP) and the improved CRITIC method to calculate subjective and objective weights by replacing the coefficient of variation with standard deviation, uses the ideal solution-based method to determine their combination weights, and combines the VIKOR method to calculate the comprehensive evaluation values of candidate cement suppliers. After that, the proposed approach is applied to evaluate and select ten cement suppliers for concrete production plants, and the results are compared and analyzed with those using the traditional method. The results of the comparison show that the proposed strategy can be scientific and reliable, helping managers to make the right decision under the background of new and old driving energy conversion in China.

Integrative Performance Assessment of Electrical Distribution Networks: An Integrated Indicators and Weight Processing Strategy

“…CRITIC is a multi-criteria decision-making method. The IAHP-CRITIC Method integrates the AHP method with the CRITIC method to provide a comprehensive and objective approach for determining the weights of evaluation indicators [17].…”

Evaluation and Temporal-Spatial Evolution of Regional New and Old Driving Force Conversion in Shandong Province

“…Correspondingly, its similar s abroad is named "industrial transformation and upgrading". Since then, studies re to the new and old driving force conversion has gradually attracted the attention searchers, and relevant theoretical literature has begun to appear constantly [11][12][13] ure 1 describes the basic framework of new and old driving force conversion in C and believes that the new and old driving force conversion can be achieved by a shift government-led to government-guided, from economic fields to social fields, from cr demonstration to all-round promotion, from factor-driven to innovation-driven, and progressive innovation to subversive innovation [14,15]. With the persistence of the impact of COVID-19 on the industrial system, there urgent need for the continuous conversion of the new and old driving force that can port the growth of "new normal" economy in China.…”
