“…These points are close together and distributed along the arcs. Algorithms for solid waste route are considered to belong to Capacitated Arc Routing Problems (CARP) (Amponsah, 2003). The Capacitated Arc Routing Problems (CARP) arises when arc has associated with it a positive demand and the vehicles to be routed have a finite capacity (Greistorter, 1994).…”

ABSTRACT:Routing of solid waste collection vehicles in developing countries poses a challenging task.New decision procedure for solid waste collection problem was introduced in this study. The problem objective was to minimize the overall cost, which was essentially based on the distance travelled by vehicle. The study proposed heuristic method to generate feasible solution to an extended Capacitated Arc Routing Problem (CARP) on undirected network, inspired by the refuse collection problems in Nigeria. The heuristic procedure consists of route first, cluster second method. The computational experience with the heuristic in Onitsha was presented. The technique was compared with the existing schedule with respect to cost, time and distance travelled. The adoption of the proposed heuristic in Onitsha resulted in reduction of the number of existing vehicles, a 22.86% saving in refuse collection cost and 16.31% reduction in vehicle distance travelled per day. The result revealed a good performance of the proposed heuristic method, which would be useful in vehicle scheduling. @ JASEM

“…Tsiliyannis (2005) uses a hybrid mathematical/heuristic approach to assess different reuse/recycle packaging waste schemes. Amponsah and Salhi (2004) use a heuristic approach to solve the problem of collection, transport and disposal of solid waste in developing countries. Jayawardhana et al (2003) developed a rule-based expert system with application on organic waste composting in Sri Lanka.…”

Decision support systems (DSS) are used to aid at solid waste management, a tedious problem with many technical, economic and social constraints. The main DSS available are briefly presented and the development of a novel system, ReFlows, is described. The novelty of the developed DSS consists of the detailed analysis of the collection subsystem and in particular the source separation and collection programs for recyclables materials. ReFlows utilises mathematical equations for material and financial flows, organised in several subroutines, to simulate the various sub-systems of an integrated solid waste management system and may be applied to any geographical scale, from the local to the national. The model, currently developed in MATLAB, is applied on recycling scenarios based on the degree of expansion of the different source collection schemes currently operating in Greece.Results are presented at a national (Greece) and a local level (Municipality of Athens). The main outcome of the study is that full expansion of the existing schemes may not fulfil the recovery goals for packaging waste in Greece. Improved collection schemes are required, based on more pilot programs in order to investigate the optimum recycling strategy.

“…A study conducted in Ghana outlined the collection system and design aimed at significant cost savings focusing on the utilization of waste containers fitted with level sensors and wireless communication equipment, which alerts the waste collector's access to information on the status of each container (Amponsah and Salhi, 2004). Transporting of waste can be done either using the collector trucks, canal or rail.…”
