A STUDY OF GIS BASED DECISION SUPPORT SYSTEM ON PRIORITIZING YEARLY PLANNING OF DRAINAGE ENGINEERING IN TAICHUNG COUNTY

摘要

Due to financial constraints of local governments, budgeting public work projects can be highly politicized affairs. But as the economy grows, people are demanding higher standards of government service and want public works projects performed using only objective and scientific methods. This study uses overall evaluation and Delphi methods as well as non-probability questionnaires completed by county and city governments and village and neighborhood chiefs to set up a decision analysis model for the planning of drainage engineering projects in Taichung County. Furthermore, a management support system can be developed with the aid of geographic information system to provide decision makers with sufficient information to effectively and fairly apportion the yearly budget.
