Abstract
There are many studies on spare parts planning in automobile maintenance industries. There is need to integrate budgeting constraint and operational dynamism into the planning for sustainable development in automobile industry. The essential data on automobile spare parts under service condition from three selected automobile maintenance job shops in the South-western Nigeria were assessed in order to identify criteria for budgeting for failing spare parts. Failure rate were used to group the spare parts of the automobile into criticality (highly critical, critical and less critical) and important levels. The posterior failure probability of spare parts was obtained for a future maintenance cycle time using the modified Bayesian probability model by integrating spare parts criticality into the system. On this basis, spare parts planning system related to failure analysis and grouping, choice of maintenance policy, and expected cost of maintenance/budgeting were determined. The system model was implemented on three job shops that were responsible for the maintenance of three brands of vehicles A, B, and C. The results from the study showed that maintenance workshops witnessed increase in annual budget saving from 26.82% to 80.17%, 80.16% and 82.70% under one, two and three - inventory capacity respectively.

Abstract
Palm oil unavoidable uses such as edible oil, soap, margarine and so on has led to the needs of more efficient, mechanized and automated method of processing palmfruits to substitute the traditional and crude methods of digesting palm fruits, with its bulk of demerits ranging from low production capacity, hygienic nature, large consumption of time and energy. The faculty of Agriculture farm in Ekiti state university needs this palm fruit digester to assist the facilitation of farm produce processing, to increase internal revenue, provide employment opportunities and reduce rural-urban drift and its consequences. This design was based on series of experiments especially on the basic raw material –palm fruits to ascertain its physical properties, which aided in the determination of the machine's capacity, power requirements and other design considerations. The constructed palm fruit digester was heater in a laboratory and field tested and the functional level was found to be satisfactorily. This machine has a digesting capacity of about 620kg in one hour and an efficiency of 62.23%. The cost estimation of the machine is comparatively cheap and affordable by small scale entrepreneur.
Keywords capacity, digester, efficiency, machine, palm fruits.
