Abstract
Cement is literally the Cornerstone of today's
building and civil engineering industries throughout
the world. The demand for cement in Nigeria far
exceeds the supply from the local industry. The local
industry has a total installed capacity of 5.42
million tons per annum. As at 1984, the total local
cement production is 3,010,000 tons (See Appendix 1.1)
as against the annual demand of 7,000,000 tons
(Business Concord, 1987).
It is therefore imperative that all feasible
cost reduction measures are used in running the
industry. This will improve operations efficiency,
improve its profitability and allow for further
re-investment. This will bring about the necessary
expansion and growth in the industry to meet our
cement requirement, which will result in some savings
of our meagre foreign exchange earnings.
The Cement Company of Northern Nigeria, Sokoto
was established by the former Northern Region, in
partnership with a German firm in 1962. The company
started production in 1967. Since that time, the
company has been operating at a loss. Business
organisations that are not profitable need to be
studied in order to solve their problems.
This study is aimed at exploring the
possibilities of applying operations research
technique (Pert Network analysis) in the kiln shut
dov/n maintenance practice of the company to reduce
its operation costs, It is hoped that, the study will
assist CCNN as well as other cement companies in
the country in planning and scheduling of their
kiln shut down maintenance practice at optimal cost.
The data for the study was collected from the
company's maintenance and production records and
interviews with company executives. A Pert Network
Diagram was drawn, the critical path and the normal
cost associated with the critical path was
determined. The cost implication of crushing some
activities within the critical path in relation to
plant downtime costs was analysed. The optimum crew
size was also determined; and suitable recommendations
made.
