Study On The Risk Of Household Garbage Transportation Network

Garbage transport is an important part of living garbage disposal system. It is a kind of special transportation problem constraints. In the garbage transport, impact on urban, social and economic effects, garbage removal system has been one study relatively weak link.One of the biggest constraints in terms of risk to the existence of the transport network, due to the different sections of the risks inherent in each, making the risk of transport vehicles in the transport network, caused by traveling road show different dynamic changes. When the starting point of the existence of any transport vehicle into the transport network requirements for how the transport vehicle scheduling decisions in order to achieve the target for analysis. Through the establishment of the target model and design the decisions and analysis the decisions, between transport risks, transportation costs and transport efficiency of the three to seek balance. And get the following results:(1) Small transportation needs in the density, the maximum value of the minimum fixed risk path policy applies to any section of the risks unconstrained care the strategy can be a good use of vehicle information, you can determine the path of the vehicle after driving into the network, so that the local risk optimal scheduling, improve transport efficiency.Shortest biggest risk decision applies to any sections in the case of risk constraints, the strategy to maximize profits from the operator’s point of view not only the value of profits per garbage truck, but from the viewpoint of subjective factors in the transport network vehicles less short-distance transport, in a sense, reducing the impact on the city’s garbage truck.(2) In the transport needs of higher density, the maximum fixed risk strategy sections of road risks applicable to the case of the fairness requirement, when the transport vehicle into the transport network needs to focus appears simple network requires total risk minimization may lead to the risk of a single road the worst problem, the strategy can better overcome the contradiction between the global optimum and local optimumThe maximum number of vehicles considered decisions from the perspective of efficiency of waste transport vehicle scheduling problem, but also take into account the cost considerations, the need for large amounts of access to the network, but in the case of vehicles outside the network stagnant In today’s growing demand for waste transport the actual situation, the policy more in line with the needs of the actual situation.
