Abstract
Ridding our cities, towns and communities of filth has been one of the major concerns of various governments in Ghana. Metropolitan, Municipal and District Assemblies have the responsibility of ensuring that the populace is not engulfed with filth to the detriment of their health.
Owing to the increasing prices of petroleum products and high maintenance cost of vehicles used in the collection and transportation of solid waste by Zoomlion in the Sunyani Municipality. This thesis sought to determine the number of trips each type of vehicle (skip, compactor and roll-on) used in the transportation should go per day to minimize operational cost.
The problem was formulated as an Integer Linear Programming problem and was solved using the software called Linear programming Software ( LIPS).
The results show that if only one skip vehicle makes 14 trips per day, the expected quantum of solid waste needed to be hauled to the landfill site at Asufufuo, 5km away, per day, can be achieved at a minimum cost of GH199.92.
