DESIGN AND IMPLEMENTATION OF PRODUCTION PLANNING MANAGEMENT SYSTEM OF SURVEYING AND MAPPING PROJECTKEY WORDS: GIS，Design，Analysis，Application，Management，ProductionABSTRACT:With the development of photogrammetry and spatial information sciences, we have found many new methods to solve the technical problem in surveying and mapping But there is a little research on the project Traditional management method is complex and time- Now, we need use new technique to improve the management method for enhancing management Taking “National Western Surveying and Mapping Project on 1:50000 Topological Maps Blank Area” as an example, this paper focus on production planning The project is remarkable, not only the task and extent is tremendous, but also the staff and stuff are The Blank Area has atrocious weather and extreme All of the conditions increase the project management For reasonable planning and logical budget, we designed and realized a production planning management system to give the decision support to the This paper studies the system’s requirement analysis, system structure and function in INTRODUCTIONNowadays, Geographical Information Systems(GIS) are powerful and useful as means of information, visualization and research tools(Quan Bao,2004) Most GIS software is more suited to providing limited types of output than as a tool to support, at anything other than a superficial level, tactical or strategic decision-making To improve the usefulness of GIS as a decision support tool, two needs are First, decision-makers require methods that allow them to easily select alternatives across a number of relevant Second, it is necessary to explicitly recognize that most decision-making processes involve multiple Since problem solving id often characterized by multiple and conflicting objectives, methods that contribute toward more a completely aiding decision system are
