Material is to maintain the normal operation of all kinds of resources integrated, the procurement is a significant means to ensure the enterprise supply as material purchasing is the purpose of the enterprise to obtain the value in the process of material in the production and business operation. Material purchasing constitutes the main part of enterprise cost, the success of the procurement is purchasing goods and materials to maximize value-added and it is directly related to the cost management of enterprises and the material purchasing, in order to further improve the enterprise＇ s buyer need to constantly enhance their own professional level that actively explore a variety of procurement mode, different procurement methods to complete the procurement, to seek for more high-quality supplies for the enterprise, at the same time, improve the production and operation of the further enterprises benefits.展开更多

This paper starts with the actual problems in the process of bidding procurement management of construction equipment in our country, briefly expounds the current situation of construction equipment procurement in our country, puts forward a series of management requirements for bidding procurement of equipment, and gives corresponding solutions and suggestions for optimizing the management of bidding process of construction equipment in our country. It is hoped that these measures can solve the practical problems and deficiencies, improve the procurement management process of engineering equipment in China, and provide suggestions for the sustainable development of China's construction industry.展开更多

Therefore, at present, enterprises should learn and implement new production concepts in an all-round way, and carry out reforms and innovations from various aspects, so as to improve the development potential of enterprises. Based on the procurement management under the supply chain environment, this paper analyzes the effective ways to guarantee the quality of procurement cost management. The research in this paper can provide more research ideas for the research of supply chain management, and can also improve the cognition and understanding of procurement management from more directions, and enhance the scientific nature of procurement management.展开更多
