Abstract
This thesis seeks to provide waste management companies, especially Kumasi Metropolitan Assembly-Waste Management Department (KMA-WMD) an alternative way of allocating limited collection trucks over the numerous collection points and to ensure minimum total cost. Data were collected from the KMA-WMD their contracted companies as regards to the waste generation levels of all the collection points in the metropolis, and how much of these refuse are collected to the two dump sites over a period of three months. The data gathered were modelled as linear programming problem with clear objective functions for each month under consideration subject to its associated constraints. These objective functions and constraints were minimized using a computer software solver, EXCEL, to generate an optimal solution. The objective function value represented the minimized cost for the period under consideration if the waste generation levels of all the collection points were constant within the data collection period.
