Study On Refined-oil Distribution For Shandong Marketing Company Of PetroChina

In recent years, the logistics as"the third profit source of business" caused a great deal of attention in the domestic industry. About theory research and practice of the logistics optimization, is also in full swing and continued to deepen.In this paper, it researches and investigates the problems of refined oil secondary allocation optimizes. Based on actual business of Shandong Marketing Company of PetroChina, from the discovery of the questions, and the analysis of the issue, drawing on the results of research at home and abroad ,in order to reduce logistics costs and increase economic efficiency as the goal, mainly from the gas station to accurately forecast sales volume, oil depots and gas stations a reasonable inventory control, gas stations replenishment point and the best determination of purchase quantities, delivery time windows, as well as the scientific development of distribution plans and so on, which is closely related to various aspects of the distribution business.In the study of forecasting sales volume of gas stations, taking the actual business data in Shandong marketing company as an example, after the comparative analysis on forecasting the effects among the current commonly used arithmetic average method, moving average method, exponential smoothing method, It selects moving-average method as the quantitative prediction method, and establishes the prediction model of combination quantitative prediction and qualitative prediction.In the study of oil depots and gas stations at a reasonable inventory control, replenishment stations with the best determination of distribution volume, and distribution time window, taking the three major research goal including the lowest cost distribution, inventory capital reasonable occupied, the efficiency of vehicles enhancing into account ,it sets up the optimize model separately.Finally, it conducts the key research on the science formulation to allocated and dispatched plan, through two terrace works both the gas station making up the goods plan to produce and the vehicles allocated and dispatched to dispose reasonably, and has established the optimized model separately, and chose the genetic algorithm to take the solution method. In makes up the goods plan production to the gas station in the research, to avoid unreasonable occurred, established the gas station to make up the optimized model which the goods plan adjustment and the fuel depot inventory control unified, it is still the innovation in the present refined oil allocation optimization research area.This article studies the primary coverage, has basically covered refined oil allocation service each key link, and has established the science solution model, has the strong feasibility, has the practical guiding sense to realize the optimizations of refined oil distribution for Shandong Marketing Company of PetroChina.
