Based On Mixed Particle Swarm Optimization Algorithm Full Vehicle Logistics Network Optimization

In recent years, along with market competition day by day frigid and cost pressure daily increase, the domestic entire vehicle physical distribution enterprise focused on minimizing fixed costs of facility location and transportation costs. However, automotive manufacturers consider influences of customer satisfaction because of fierce competition. Therefore, the whole finished vehicle logistic industry is confronted with the increasing costs and competition. To optimize the logistic activities involved in transporting finished vehicles from the plants to retailers and reconcile the contradiction between cost and services quality becomes the most pressing tasks. The warehousing network is the entire vehicle physical distribution foundation and the core, relates the physical distribution cost, the efficiency and the service level directly, therefore the warehousing network optimization belongs to most important also the effective physical distribution optimization.Based on a set of quota technology and the qualitative technical integration methodology, a program of modeling and algorithm of finished vehicle logistic network optimization is presented. Firstly, based on the manipulation of full vehicle logistic network and integrated inventory, multimodal transportation and quality of service to customer, an optimization model is presented. In addition, a complicated multi-plants network is disassembled to some single plant networks. Then, those sub networks are optimized separately and communicated with each other at the right time. At last, a PSO algorithm mixed GA and MS is presented. Among the mixed algorithm, GA is embedded to solve the difficulties of updating the particles in the binary code system; the roulette algorithm is embedded to eliminate worse particles; SA is embedded to control convergence of particles. Afterwards, through the consult massive literature material, has studied the ordinary cargo physical distribution network optimization techniques domestic and foreign research and the application achievement, induces the content which the entire vehicle physical distribution may refer and profit from, according to the above and had determined the entire vehicle physical distribution warehousing network optimizes the key technologies research the technical route.The paper widely is analyzing the domestic and foreign research results in the foundation, unifies the entire vehicle physical distribution profession actual condition, proposed suits a domestic entire vehicle physical distribution characteristic warehousing network optimization techniques——a set of quota technology and the qualitative technical integration methodology, in which quota technology mainly focuses on the establishment most lowers take the physical distribution cost as the goal mathematics decision-making model, has introduced the heuristic algorithm, and unifies the computer technology to carry on the solution; The qualitative technology has designed the pacing factor target appraisal system based on the profession present situation, and profits from Deuel Philippines methods and so on expert law, analytic hierarchy process, established the corresponding analysis model to use in appraising the decision-making. Afterwards, the present paper union domestic some well-known entire vehicle physical distribution enterprise's actual service data and the network optimization practice, to the optimization techniques which proposed has conducted the real diagnosis research, has obtained the satisfying effect, thus has confirmed the technical scientific nature and the validity.The paper first bases on entire vehicle physical distribution this more specialized and an individuality domain, and the pressing angle embarked from the necessity, elaborated studied the entire vehicle physical distribution warehousing network optimization techniques the main purpose and the significance, as well as work achievement and innovation spot. Afterwards, through the consult massive literature material, has studied the ordinary cargo physical distribution network optimization techniques domestic and foreign research and the application achievement, induces the content which the entire vehicle physical distribution may refer and profit from, according to the above and had determined the entire vehicle physical distribution warehousing network optimizes the key technologies research the technical route.In third chapter of paper, rested on the technical route which established of the entire vehicle physical distribution warehousing optimization network, deep research is done. In the fourth chapter of paper, united enterprise actual service and based on the methodology, the satisfying optimization plan has been received.In the end, reviewed the process and achievement of the research, analyzed the deficiency, proposed the pending further studied question, and then made the forecast to the next research aim and the direction.
