Study And Application Of A Logistics Distribution Decision Support System In Oil Marketing Enterprises

With the rapid development of E-commerce, logistics delivery encounters unprecedented challenges as well as opportunities. Due to the expansion of the logistics network's scale and a huge increase in volume of logistics, enterprises will be faced with a series of problems while it carries on logistics distribution. Such as how to deliver goods economically and reasonably, how to guarantee distribution systems work effectively and low-costly and how to provide their customers with logistics value-added services beyond the traditional logistics business and so on. Decision support system can handle with the problems effectively associating with merits of human and computer.Oil products distribution is the last and the most important logistics link in the whole petroleum chain. It faces End-Users directly and can help to achieve enterprise profits. This paper puts the theory of decision support system into oil products distribution that should decrease distribution cost and increase velocity and return-rate of capital greatly to enterprise. This paper puts the theory of decision support system into oil products distribution that should decrease distribution cost and increase velocity and return-rate of capital greatly to enterprise. Therefore this paper sets about study on it, and its main achievements are as followed:1. Based on references in domestic and international journals, the paper points out direction of oil products distribution and decision support system, presents the meaning of topic selection and the foundation of research project.2. The paper have made qualitative analysis and study on definition, composition, key technologies, architecture of decision support system and its development orientation, established math models for all kinds of distribution, especially for the style of single-distribution-center and multi-user, while combining realistic status and summarizing logistics distribution models in china, made preliminary research on solving algorithm for distribution models.3. By means of analyzing actualities of distribution management and planning institutions of a regional company and of studying two aspects of distribution optimization and business process profoundly, the paper set down a suit of feasible optimization projects.4. Based on analyzing and study ahead, the paper have designed distribution modules, transportation modules and planning modules for the DDSS, made its whole frame formed. The DDSS have also gotten realization in computer while its database applies relational data structure.In the end, the dissertation summarizes the whole article, and presents an expectation that there are many problems to be solved.
