Abstract


Occupies an important position as an integral part of the municipal waste management system , garbage collection and transportation system . Lack of theoretical guidance , garbage removal system has become one of the weakest link in the garbage integrated management system , the urban waste transportation system improvement and optimization of the efficient operation of the municipal waste management system plays a vital role. In this paper, based on in-depth analysis of all aspects of city garbage removal system , through the analysis of the characteristics of urban waste reverse logistics , the mathematical model of the city garbage removal system , including the following three aspects: 1 , choose a city must existing refuse collection point range to build a garbage transfer station , the refuse transfer station to the distance of the landfill and waste transfer stations and the maximum distance to the collection point minimum . The location method using Voronoi technology , the establishment of the mathematical model of the problem solving algorithm design and analysis of the computational complexity of the algorithm . 2 optimization problem of refuse collection routes with time windows ( VRPTW ) , each collection point in the collection routes added time window constraints , consider the noon lunch break of one hour , and the garbage truck load and no real the load operation cost spent distinguish calculations. Minimum total transportation costs as the objective function , a mathematical model , and the use of Solomon given insertion algorithm for solving steps . 3 , the the Waste Transfer phase transfer station demand has dynamic characteristics , only know that at this moment the current demand , future demand sequence is as yet unknown , and when the transfer station on demand by a garbage truck , the transfer station garbage transported to processing field , so the proposed garbage transport the busy vehicle routing problem . Create a mathematical model , and the line is busy K garbage truck scheduling problem limited circumstances , given the competitive strategy and competitive ratio .
