英文摘要	The integrated design modeling between facility location, inventory and transportation and its solutions has been among the hotspot problems of modern logistics system theory and operation research.The integrated design modeling and solutions of distribution logistics and supply logistics are made profound researches. This main results obtained may be summarized as follows: 1. Logistics system design research literatures review. Such logistics system integrated design problems as location-routing, inventory-routing and location-inventory are reviewed, among which research hotpot, difficulty and drawback on modeling and solution are analyzed. 2. Automobile logistics system integrated design problem research. The new distribution logistics system structure is designed, which utilize fully transportation economies-of-scale between plants, consolidation centers and distribution centers. The automobile logistics system integrated design model is presented, which provides an integrated view of transportation economies-of-scale, inventory and facility costs as well as service quality. The flow prediction algorithm is presented, which is embedded respectively in genetic algorithm and particle swarm algorithm. Solution framework and key step of these hybrid intelligent algorithms are expatiated respectively. Many case study simulations are given to confirm the correctness of the optimization model and the effectiveness of the solution. According to such these critical parameters variety as penalty cost, inventory control policies and transportation economies-of-scale, the change rule of automobile logistics system design scheme is discussed. 3. Location-inventory system integrated design problem under stochastic demand. The location-inventory distribution system design problem involving one supplier, candidate distribution centers and multiple retailers under normal distribution demand is studied. The integrated 2-echelon inventory control policies with incapacitated facility location model is presented. A Lagrangian relaxation solution algorithm for realistic scale problem is proposed. A number of heuristics are listed for solving effectively sub-problems. Sub-gradient method is improved. Simulations are given to confirm the correctness of the model and the effectiveness of the solution. Finally, the sensitivity of potential cost reduction, compared the sequential approach, to changes in inventory control key parameters including demand variance, holding cost, lead-time and service level is discussed, which confirm the requirement and feasibility integrated location with inventory. 4. Integrated product development process with supply logistics system design problem research. The integrated product development process with supply logistics system design model framework is presented. The parts process mapping and decision-making process on outsourcing is designed. 5. Logistics system integrated design decision-making prototype system research and development. Logistics system integrated design decision-making prototype system is developed, Framework of prototype system, system design based on UML and execution interfaces in part are outlined. The research results presented above enrich the content of logistics system design theory, and provide more sufficient scientific evidence for decision makers making logistics system design，which is worthy of practicable application.
