Study On The Target Control And It's Performance Evaluation For The Suppy Chain Management Of Highway Construction Project

With China's rapid economic growth, there is the bottleneck of factor in which infrastructure of highway limited chinese economic' growth, a large number of highway construction infrastructure network as the central government and the local governments at various levels of economic growth means necessary and important measures.Over the past 20 years, large amounts of money are invested into the tide of highway construction. Such as survey and design firms, construction firms and supervision firms, most highway construction enterprises are full of orders and business.With these, all kinds of highway construction enterprises included of the owners only emphasize the scales, but neglect the benefits of constuctions, which results in that the relationships among the participations of highway construction seem to be adversarial and short-term all the time in the highway construction market and the specific environment of highway projects.Besides, in all phases of project execution and process, with the separation and disjunction of plan, implementation and management operation from each other, the coordination and communication are difficult on the tissue interface and process interface. But fortunately, the successful applications of the supply chain management in manufacturing provide new thinkings and solutions for highway construction enterprises in improving their management efficiency and core competitiveness.Make to order is one typical supply chain represented to highway construction project, featuring that is concerntrated, provisional and complicated by its aspect of structure and function.Involved in the supply chain relationships and behavior are considered, highway construction projects with three attributes:network, attitude and cooperation.Highway construction projects based on supply chain management is a kind of supply management. Suppliers, subcontractors, the designers, the owners formed as a supply and demand relation with the construction of the whole construction chain, the supply and demand relationship among the longitudinal and transverse integrated management, and the traditional management mode of highway construction are fundamentally different.This paper mainly studies the highway construction projects of supply chain management, cost, quality, schedule control strategy, and performance evaluation of highway construction example verified, Specific content as follows:(1)Quality is the fundament of highway construction projects.This paper builds the quality control matrix based on the supply chain in highway construction projects.In general, the quality of highway construction influenced by costs is nonlinear. Along with the increase of the input, the quality level to the sensitive degree of input costs will drop off. And along with this change, according to the different preferences, there is a reasonable optimal solution.In this paper, genetic algorithm is used to manage and optimize the quality cost of highway construction projects. In the coding process, we transform the optimal level into a binary string, compute the probability of each individual choice in group, and use the roulette selection method rounds.Then cross and use mutation arithmetic until it reaches the preset termination algorithm conditions. This paper takes a highway construction project as an example and uses the genetic algorithm for the optimization of quality cost proposed by this paper to verify its feasibility and rationality.(2)Cost has been one of the important competitive weapons among the competition of the highway construction company. This paper defines the cost of the highway construction projects of supply chain, analysising the categories of the cost of highway construction projects of supply chain, launched a study of transaction costs with emphasis on highway construction projects of supply chain. Papers on highway construction projects of supply chain efficiency, transaction cost characteristic dimension and the influence factors on the detailed analysis, has established the transaction cost evaluating indicator system, and selected samples of the 30 highway construction projects to determine the target weight using AHP (Analytic Hierarchy Process), and established the transaction cost evaluation model for the highway construction projects of supply chain based on TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) law.(3)Whether does the road project progress smoothly in the anticipated time and is available, direct relation investment benefit display.This article has studied the highway construction project supply chain total progress characteristic and the influencing factor, has discussed the supply chain progress and the cost mutual influence mechanism emphatically.Supply chain management for highway construction projects of progress control focuses on highway construction projects from the whole life cycle, is coordinated each stage the construction time, serves the benefit most superior purpose by the time.This article proposed based on the relocation-construction-operation's progress cost optimization principle, using matlab software software simulation system constructed and road construction projects with specific examples demonstrate the feasibility and effectiveness.(4)Performance evaluation to supply chain efficiency, this paper on Supply Chain Performance Evaluation Based on the theory, from supply chain quality, cost and schedule control construct three road construction projects supply chain performance evaluation system chosenapply to highway construction project supply chain performance evaluation method-data envelopment analysis to explain the data envelopment analysis the basic principles. According to the theoretical analysis above, we use the measures of data envelopment analysis to evaluate the performace of the supply chain of hunan CZ highway construction project and another three highway construction projects, and in-depth analysis their evaluation results.In summary, this article is committed to using research findings to solve the prominent problems which the highway construction project management now faces.Based on the supply chain of China's highway construction projects, we build the related model of quality, cost and schedule control, providing new research methods and management thinkings for optimizing the costs of transaction, quality and schedule.These continuously improve the management standards of performace on the supply chain of highway construction project and promote the benefits of highway constructions.
