Combined intellectual and petri net with priorities approach to the waste disposal in the smart city

Abstract

The disposal of solid household waste from large cities is one of the important parts of their environmental safety system, which is a part of the “Smart City” concept. The suggested approach is based on Petri net with priorities that allows to simulate the process of solid waste disposal. The way which allows to evaluate the effectiveness of the use of the specialized expert system is considered, also. The priorities of Petri net transitions are considered as probabilistic characteristics of the live transitions in the network. Changing priorities allow to customize the Petri net behavior according to existing empirical data. Results allow to investigate the impact of the whole process quantitative characteristics on the solid waste disposal such as speed of filling of waste containers, the number of trucks used, the waiting time for the job assignment and some others. The main result of the work is the evaluation of the effectiveness of the expert system in the management of specialized transport for the removal of municipal solid waste. The simulation results are based on the specified probabilistic levels of making the right decision when using it.
