Research on Decision Support System for Location Selection of Rural Sewage Treatment Facilities Based on GIS and Intelligent Communication

An intelligent diagnostic decision support system for the location diagnosis of urban sewage treatment plants was developed. Using positive and negative ways to reason, the knowledge structure in the knowledge base is presented to users in the form of logical tree, which is convenient for users and maintenance. The decision method of group site selection across the whole range of administrative divisions is proposed. Combined with geographic information system, the final decision is made on the solution results of group location multi-objective planning, and the sewage treatment plant site selection case is tested. The scientific and rational layout of urban domestic sewage treatment plant is improved based on geographic information system (GIS) and multi-index planning. The system is based on the constructed DSS, with the help of the intelligent model of expert system, auxiliary data model, graph model and image processing model, to realize the comprehensive fault diagnosis. By tracking the operation of the real-time monitoring system, the dynamic database can be created to timely update the address information of the sewage plant, thus improving the parallel processing efficiency of the system.
