The Study And Design Of Vending Machine Operation Management Expert Decision System

Vending machine develops rapidly and spreads widely. Meanwhile, the increasing cost of operation management puts great pressure on operators. Expert Decision System is introduced into Vending machine operation management, which makes the decision in Vending machine operation management intelligent and automatic.Firstly, the thesis takes research on expert system technique and decision support system technique, mainly supported by inference engineer of expert system and combing decision support system, the system design is proposed . Secondly, basing on the analysis of realistic demand for vending machine operation management, the system architecture of vending machine operation management expert decision system (short for VMEDS)is designed. And prototype of expert system is built.Moreover, according to the detail demands of Vending machine operation management, a part of decision support models are designed. MTSP is solved by the genetic algorithms to minimize the cost of the merchandise distribution. The perfect coin supplement is achieved by probability Statistic method. Vending machine operation management failure tree is set up, and the knowledge library for vending machine failure diagnosis model is designed to intelligentize the failure diagnosis. The simulation results of several models show the feasibility of models.Lastly, C++ and CLIPS mixed program is put forward to implant in VMEDS. And CLIPS is successfully applied in the development of failure diagnosis decision support models.A feasible expert decision system for vending machine operation management is proposed in the thesis, which is able to reduce the cost of vending machine operation management and improve the efficiency of the management.
