Building Site Selection of the Light Industry Plant Using AHP and GIS in NSDL Environment

Building site of the light industry plant should be selected with full consideration of land, electricity, water, transport, raw material supply and environment protection condition of the corresponding area, otherwise it may have a negative effect on the cost of product. Therefore, the optimal selection of building site is very important to the economic revival of enterprise. We have considered a plant building site selection with AHP (Analytic Hierarchy Process) and Geographic Information System (GIS) in NSDL environment. NSDL (Net-oriented System Language) is a complex system modeling tool, which has been developed by combining the advantages of Petri Net with Object-Oriented Programming Language VB (Visual Basic). AHP is a comparative assessment method using human sense, which models the influence of the criteria associated with decision making into a hierarchical structure and allow to choose the best among alternatives to be selected. AHP is widely used in various fields of economy, military, society, management, education, medicine, etc. Also, this method can deal with qualitative or quantitative data. Unlike the other AHP tools, the hierarchical structure models were made by Petri net diagram of NSDL, provides the automatic information link with the AHP module to improve the intuition, flexibility and convenience of decision making tools. In addition, using the object-oriented VB script language of NSDL with powerful integration ability, ArcGIS were combined to perform geographic information analysis to determine the optimal plant building site.
