The Study Of CNPC Dalian Maritime Corporation Coastal Refined-oil Transport Inventory-routing Problem

Oil is a nation’s "industrial blood". Our country’s demand and consumption of crude oil and refined oil also showed significant growth trend in recent years. However, in China, refined oil refineries mainly concentrated in the Northeast and Northwest regions consumption areas mainly are in East and South of China. Therefore the transportation route of refined oil is "north to south,"" east to west ".Shipping has the advantage of low prices in the transport of bulk cargoes. It has also become one of the main modes of refined oil transport in China. However, along with the importance of oil products by sea, coastal transportation of refined oil is faced with the inventory-routing problem. Due to the refined oil industry is a monopoly industry, some national companies are ignoring the optimization of logistics management and they are lack of proper transport plan, resulting in lower overall supply chain efficiency.China’s domestic oil market gradually involved in the international competition is an inevitable trend. In this trend, low-cost and high-quality products distribution channels for oil sales is crucial for survival and development of enterprises. At this point, if companies are still only on production without re-circulation and inventory management which can easily be eliminated in market competition. Based on this, it promote CNPC Dalian Maritime coastal refined oil transport company’s inventory-routing management, optimization of transport paths, making the company’s inventory and transportation costs minimized, improving corporate earnings. From here, I hope this article can have some inspiration arid help on other refined oil road transport enterprises.On the basis of careful analysis and study nearly10years’related research, we constructed a mixed integer linear programming model for solving the problem in this article, the objective is to minimize the cost of inventory and transportation costs.
