Landfill location selection is a multi-criteria decision problem and has a strategic importance for many regions. The conventional methods for landfill location selection are insufficient in dealing with the vague or imprecise nature of linguistic assessment. To resolve this problem, fuzzy multi-criteria decision-making methods are proposed. The aim of this paper is to use fuzzy TODIM (the acro...

Community Development Participation or KKN (Kuliah Kerja Nyata) is an annual activity at a university. The ultimate goal is the students learn to live in the community to identify the various developmental problems. The expectected outcomes are, the students were able to contribute ideas to solve the problems in a short term time by using the provision of knowledge gained during college. Theref...

background and purpose: an appropriate solid waste (sw) disposal has been a major problem in municipal environment. the use of landfills is the most economical and environmentally acceptable method for the disposal of sws all over the world. however, landfill leachate can cause environmental issues such as soil and ground water pollution. so, finding suitable land fill site is one of the most s...

in this paper the conditional location problem is discussed. conditional location problems have a wide range of applications in location science. a new meta-heuristic algorithm for solving conditional p-median problems is proposed and results are compared to those of the previous studies. this algorithm produces much better results than the previous formulations.

This paper presents a multi-objective optimization model for the design of a waste management system consisting of customers, transfer stations, landfills and collection vehicles. The developed model aims to simultaneously minimize the total costs, greenhouse gas emissions and the rates of energy consumption. To tackle the multiple objectives in the problem, we utilize an interactive fuzzy prog...

The solid waste materials in cities are the natural outcome of human activities. Most of our cities and municipalities in third world countries like India is a major concern of the government due to the health problems associated with improper disposal of waste. Several factors are considered in site selection for waste disposal. Provision of such system appears to be a major problem due to the...
