A Study Of Location-Routing Problem Based On The Supply Chain

With the globalization and integration of the world economy, the competition between enterprises is also becoming globalized. In order to gain advantages in the keen market competition, an enterprise is supposed to react promptly to the market in a quickly changing environment and try its best to fulfill the customers' demands at the highest speed and the lowest cost. As for a manufacturing enterprise, how to improve the service efficiency of the distribution channel as a whole is crucial in realizing the objective mentioned above. Therefore, the enterprise needs to improve the optimization design of the logistics system.The study of Location Routing Problems (LRP) has aroused special concern in the related fields and achieved great development worldwide since its emergence. At present, the optimization objective considered in the LRP study usually is the cost effectiveness of the distribution channel. However, in recent years, with the requirement pressed on logistics management is rising continuously in a world embraced by new technologies, enterprises are supposed to extend their understanding of service, realize the integration of distribution and related services to customers, as well as reconsider, from the strategic prospective, the logistics optimization and the way to put it into strategic management practice. By studying the logistics cost from the angle of supply chain, enterprises are able to grasp the general picture of logistics cost together with logistics operations time systematically and realize the total logistics cost effectiveness in the supply chain as well as the rapidest response. Therefore, to build up the LRP optimization model based on logistics cost and response time in the supply chain plays a significant role in the strategic decision-making of the enterprises. This dissertation begins with the process analysis of logistics activities based on the LRP of the supply chain, and then moves on with the study of the logistic network of the LRP in the supply chain, aiming at constructing a new optimization model on the basis of the supply chain.
