Optimum Stock Control Model for Farm Tractor Spare Parts in Nigeria
Abstract
This paper examines the issue of developing an effective farm machinery maintenance management strategy in Nigeria. Investigative survey data on the inventory, type and condition of agricultural machinery in Nigeria were reviewed and additional information required was obtained from relevant establishments. Data on frequency of breakdown of farm tractors and the costs of purchasing various components' of the farm tractors were subjected to scientific analysis using some operational research techniques. Based on the result of the analysis, an inventory (stock level control) model was adapted for the supply and replacement of worn-out machinery parts and components, at recorded frequencies of farm tractor breakdown. Tentative projections on the optimum level of tractor spare parts required for ten states in Nigeria were made and the result are presented.
