Research On The Theory And Technique Of System Strategic Layout Of The Logistical Network

With the rapid development of modern science technology, the tendency of global economy in whole, each country is confronted with opportunity and challenge. Modern logistics, an advanced organization mode, broadly considered as an important profit source besides decreasing material consumption and improving productivity, is playing an important role in national economy and society development. Therefore, it is crucial issue on how to comprehend the designation theory and method of logistic system, the management conception of logistics organization, logistics rationalization and so on.In the theoretic field of our country, there many discussion on logistic network planning, design, and assuredly, some research achievements have been acquired, but most of theories are fragmentary, non-systematic, and weakly applicable. Based on theory research and comprehensively apprehension of the connotation of logistical network, the article describes the theory and method of logistics network layout, and bring forward some comparable applied method and model. The main content of the article includes:(1) Elementary conception of logistics system .The article mainly discuss the conception of logistical system, type, structure, characteristics and basic steps, and analyze the classic model of logistics' system;(2) The conformity theory of logistics. Based on research on theory, the article researches logistics systematic theory, logistics system planning and design theory, logistics custom service, management, logistics establishment address selection, traffic transportation network layout, storage, stock control and logistics strategy theory.(3) Logistics system planning, designation method and technology. The article puts forward the ways and steps of logistics system designing, mainly including the constitution and realization of logistics custom service standard,the setup of logistics sites selection model, transportation network planning and route arrangement, warehousing and storage management and so on.Logistics network planning theory and method are made up of three main parts: Custom service mainly discusses custom service theory and how to confirm reasonable custom service method and model; logistics sites selection including defining the position and scale, the article develops a set of model on address selection that makes use of a heuristic arithmetic to compute and comparatively appraise the expenditure of each project, and to eliminate some unacceptable projects according to expenditure rule. In consequence, we acquires a set of optimal project through setting up the guideline system of logistics address selection planning project and applying illegibility theory to intangibly quantify each guideline, and through synthetically analyzing and sorting filtered projects; The designation of configuration and transportation network discuss configuration and transportation route address selection and the arithmetic of vehicle sort, puts forward simple applied arithmetic to transportation route selection, in reference to some practical data .
