Fourth Party Logistics Routing Problem With Common Delivery Mode

With the coming of economic globalization and knowledge-based economy ages, the corporations are faced with more fierce competition,whole market competition has become obviously internationalization and globalization.When with the constant improvement of the fourth party logistics development, both in the domestic enterprises and multinational companies to care about delivery time problem.Due to the increase of constraints to the requirements of the logistics activity is more and more strict, downstream of the supply chain enterprises and customers to achieve "zero inventory" and "low stress", has a rapid reaction mechanism and solve their own money pressure, etc., thus to upstream of the supply chain enterprise will come up with many varieties, small batch, high frequency, fast speed, diversified distribution requirements, at the same time consumers to buy the product diversification, personalization, differentiated demand distribution of many varieties, small batch, fast speed, the phenomenon of high.Both in large enterprises and small and medium-sized enterprises have irregular distribution amount, the distribution and the plan or everyday situations to reach a certain size, this will lead to enterprise "conveniently small" pattern, will waste a lot of ability of logistics facilities, greatly increasing distribution costs or lead to distribution of the impossible.For companies to adopt to the fourth party logistics distribution mode proposed by the authors in the rapidly changing market, will greatly reduce the risk of the enterprise cost, increase the market competitiveness of enterprises.In the face of the above situation, the fourth party logistics in common mode to provide the corresponding path distribution mode of transportation, it will be enterprise in the lower logistics cost and ensure the delivery service level under the premise of logistics distribution mode is suitable for their own conditions.Paper based on analyzing the research status at home and abroad, on the basis of established research object as a fourth party logistics joint distribution mode of the vehicle routing problem.First, in view of the shenzhen shun hing salt logistics company analysis of the current situation of the company’s distribution, and points out the reasons of the existence of problems, and through the research of the fourth party logistics to get the corresponding solution.Through the analytic hierarchy process(ahp) screened the company the influence factors of distribution present situation, and optimize the path for the center with main influencing factors.Second, constructed according to the main influencing factors to establish the corresponding target structure model, through the saving method of heuristic algorithm finally determine the path of the joint distribution.Finally, combining with the shun hingsalt bao logistics companies on the constructed model example analysis for further understanding of this approach.Heuristic algorithm for a common path choice of the mode of evaluation and decision provides effective tools, the analysis result for the joint distribution of environment down and said, is a very valuable reference.This article only selected a few representative influencing factors are analyzed, in the real operation process, still want to combine the specific circumstances the evaluation and selection of vehicle routing method.
