The Research Of Location Selection For Small Commodity Collection And Distribution Center In Changchun Area Based On The GIS

Our country's inhabitants distribute the characteristic are the urban population high density are centralized, the rural population relative disperser, the density is low, Expends regarding the countryside cities region inhabitant small commodity, is unable to depend on completely in the big city supply, therefore in the region the small commodity collection and distribution center solves the commodity demand basic way. The small commodity collection and distribution center has the dual nature, took a commodity servicing facility, the pursue profit is the essential foundation which it develops smoothly,also is to the business attraction basic guarantee, in other words, it is same with other commercial mesh point, is one take the profit as the guidance business center,moreover it also has the social service nature, is must the rank residential area provide the commodity service for the cities below, the government can have certain attendance in the policy. Has such characteristic small commodity collection and distribution center selected location to have to have to consider achieves two goals,first is the social service goal, also is must let the small commodity collection and distribution center be able to cover in the service area all residential areas, second is must guarantee the business may gain the satisfactory profit, like this only then possibly causes the small commodity collection and distribution center sustainable development, stable is the region provides the service.The early small commodity collection and distribution center choice many assigns by the administrative order, is not completely completes the layout from the economic and the spatial structure angle, the existence many cost waste. Because the small commodity collection and distribution center has the dual natures, therefore has the influence factor to the choice of location to have very many, for instance current economic condition, population factor, traffic conditions and ancillary facilities and so on, these factor synthesis function in concrete selected location work. The conventional selected location method, very difficult to synthesize comprehensively consideration all factors, and in consideration time also compares difficulty with quantification each factor,when analysis can have the subjectivity, has certain influence to the selected location result scientific rationality. But the geographic information system appearance, provided for us to solve this kind of question tool brand-new, the knowledge which the use economic geography and the position discussed took the rationale, depended on the GIS formidable space analysis function to establish the selected location model, thus made to solve this kind of question plan to be more scientific reasonably. This article mainly from the rationale, selected location influence aspects and so on factor analysis, data preparation, analysis model establishment, gain plan elaborates this question. The concrete selected location process is as follows:First selects uses the Turle Philippines method definite weight,the analytic hierarchy process carries on the control the method to inspect the small commodity collection and distribution center selected location influence factor the content,Sought information through the multiwheel expert, has obtained a group of concrete small commodity collection and distribution center selected location influence factor and the influence weight。Then, take this setses of sub factors as the reference, the widespread collection correlation data, and establishes the corresponding selected location decision-making database and the selected location data warehouse。Next, regarding the small commodity collection and distribution center choice of location duty, completes in the region using the suitability analysis method the suitability rank evaluation, determines certain candidate spot position according to the boundary condition。Finally selects in the network analysis the localization - - disposition analysis, determined may the demand point provide the service for the region in the service point position position, makes the algorithm improvement in the localization-disposition analysis, records each kind of configuration the transportation cost, thus may choose several relatively most to save the transportation cost the plan, carries on the comparison take this as the foundation by the policy-maker to choose a preferred plan。...
