Research On Decision Model Of Construction Contractor's Material Purchase

With the improvement of China's market economy and construction industry,China has entered a market economy characterized by competition.In the environment where the construction industry has experienced 20 years of prosperity and development,the construction enterprises have experienced fierce competition during the great development period.Understand the fierce competition in the construction industry is the construction industry's construction technology,personnel level and project management level of competition,the current stage of the construction industry,the gap between enterprises is gradually narrowing.Fierce market competition has also made profit margins smaller and smaller,construction contractors can provide low-cost high-quality building products,has become the key to the market based.When the contractor gets the contract,the contractor will need to complete the construction product within the planned duration and budget.On the basis of the completion of quality and quantity,the construction contractor through a certain cost management means to improve their own economic benefits.Project management more and more attention to the management of engineering materials,to reduce the cost of the purpose of cutting costs.This paper analyzes the advantages and shortcomings of the existing purchase model,and the fundamental purpose of the construction contractor's material procurement decision-making model is to reduce the cost of construction contractor by optimizing the cost of material procurement.And strive to establish a scientific,practical and easy construction contractor material procurement decision-making model for the construction industry in the procurement of engineering materials to provide decision-making basis to reduce the procurement contractor's procurement costs and improve the market competitiveness of enterprises.In this paper,the specific research content is:(1)the establishment of procurement uncertainty under the construction of material procurement decision-making model,the contractor's demand in the case of a variety of factors,the original purchase from a number of suppliers to determine the amount of raw materials,from a number of material suppliers The amount of uncertain engineering under the influence of multiple factors.In this case,the supplier purchasing decision-making model is established under the uncertain demand,and the purchasing decision under the influence of multiple factors is obtained through the analysis and comparison of the quotations of the suppliers under different circumstances.There are a number of suppliers of material suppliers and service providers involved in the construction of the contractor.It is possible for different suppliers to provide the same product and possibly to provide different products to meet the contractor's construction needs.In the process of construction of a single project,some kind of construction material is needed.Under the condition that there are only two suppliers in the market,the quotation of the two suppliers is used and the feasibility of the model is analyzed through the actual case Sex.(2)the establishment of multi-supplier hybrid procurement game model,when the contractor to a number of suppliers to purchase a variety of raw materials for a construction,the construction contractor will use the push procurement and pull-type procurement to a number of Material supplier procurement of raw materials,the establishment of a mixed procurement model procurement game model,the introduction of the ATO supply chain concept,built in the ATO supply chain environment,multi-supplier mixed procurement model,the contractor's construction needs in the two The demand for materials,the contractor to promote procurement methods to a material manufacturers to purchase materials to pull the procurement method to another company procurement of materials,in the pull and push the coexistence of mixed procurement mode,the contractor and suppliers Of the game process,the supplier will set the optimal production volume and price,in the supply chain to maximize the benefits of the premise,the supplier's optimal production volume and price,and to find the model under the two materials The optimal price of the supplier and the optimal yield to maximize the benefits of the supply chain and analyze the feasibility of the model through practical cases.
