Abstract

Many studies have considered the location of rural waste transfer stations, but most have omitted the impact of transportation network conditions. Traffic accessibility must be considered in optimizing the location of rural waste transfer stations, which is an important difference from the location of rural waste transfer stations. On the basis of previous studies, this study will consider the impact of traffic network on the optimization locations of waste transfer station in the rural areas. The objective of this study was to ensure the minimum Euclidean distance between the waste transfer station and the population center is the maximum, minimize the garbage transportation cost of each population center, construction costs for waste transfer stations, construction and upgrade costs for roads on a traffic network. A multi-objective facility location-network design model and an improved multi-objective simulated annealing algorithm was used to solve the problem. A detailed practical case study was used to illustrate the application of the proposed mathematical model. The results show that transportation network plays an important role in facility location optimization, and the improvement of traffic network conditions can greatly reduce waste transportation costs.

The phrase “Not In My Back Yard” (NIMBY) refers to the well-known social phenomena in which residents oppose the construction or location of undesirable facilities near their home
The convenience provided by these facilities is shared by the whole society, but the negative impacts may be only borne by some residents closer to them

Summary

Introduction

The phrase “Not In My Back Yard” (NIMBY) refers to the well-known social phenomena in which residents oppose the construction or location of undesirable facilities near their home. Examples of such facilities include landfills, waste transfer stations and thermoelectri power plants. NIMBY facilities provide convenience or services for residents, and have a strong negative impact on nearby residents (Saameño Rodrıguez, 2005) [1]. The convenience provided by these facilities is shared by the whole society, but the negative impacts may be only borne by some residents closer to them. That’s why NIMBY facilities have been resisted by people. Garbage treatment facilities are one of the public facilities with a high degree of evasion
