ABSTRACT
With globalisation taking centre stage in almost every market; traditionally monopolistic
manufacturing companies in Zimbabwe are struggling to compete with international
companies whose operations are optimised. This paper focuses on maintenance practises of
a Zimbabwean sugar manufacturer with an aim to improve the company’s asset care plans.
The company’s current maintenance philosophy and its shortcomings on certain equipment
in the plant were identified together with the associated annual maintenance costs. A
Pareto analysis on the equipment’s breakdown history was used to determine the conditions
that can be monitored using Condition Based Maintenance (CBM); and experiments to
establish the feasibility of monitoring these conditions were done. The paper then
recommends and proposes a CBM system replete with its three main elements of data
acquisition, data processing and maintenance decision making to reduce breakdowns on the
subject equipment by at most 76%.
