Abstract:In order to strengthen the source control of power grid equipment quality, solve the problem of equipment quality traceability, and achieve the whole quality control throughout the whole life cycle of equipment. Starting from the idea of big data, this paper first sets up a framework model for the evaluation of supply chain traceability management of power grid equipment based on big data, and points out the technical route of the traceability management evaluation of the supply chain of power grid equipment. Secondly, the network crawler technology is used to crawl and process the scattered mass data so as to extract information from power equipment suppliers, the evaluation index system of power supplies supplier is constructed with 5 first grade index, 8 two level index and two dimension index, and the relationship between the indexes is analyzed. Finally, how to reasonably match the index weight is explored, The three weight determination methods such as the subjective right method, objective empowerment method and fuzzy comprehensive evaluation are compared and analyzed, thus the traceability management evaluation model of power grid equipment supply chain is built, which can provide reference for the supplier evaluation and optimization of the power grid enterprises.
