(a) Research Completed.
(i) The effects of carburizing time, temperature, and percentage energizer on the case-depth and harness of steel ST 37-2 were studied. The purpose of the research was to understand the science and technology of improving surface hardness of the locally produced steel to meet the ever-growing demand (2 papers have been published).
(ii) A biobjective model was developed for production planning in a multi-stage multi-facility production system. The case considered was a situation where a Decision Maker wants to determine the quantities of materials to be fed into each production facility at each stage of production that gives maximum realization of his objectives. (2 papers published)
(iii) A study on how to harness in-house knowledge, experience and expertise for the identification and solution of perennial problems facing a company producing steels products in south western Nigeria was conducted. The study revealed that the technical staff perform routine tasks of operation and maintenance resulting in the under utilization of their skills, intellectual contribution and their innovative and creative abilities (Presented at the NIIE conference 2000)
(iv) A study on how business organizations in the developed world have been able to use Competitive Benchmarking to attain competitive edge was carried out. Drawing upon their experiences, the guidelines and framework for its application in the developing world, the potential frustrations and the implementation problems were identified. (Being prepared for publication)
(v) A model for determining the optimal process-checking interval was proposed and applied to an automobile glass manufacturing industry. The optimal process-checking interval would ensure that the sum of the costs of process diagnosis, process adjustment and deviation of product characteristics from the nominal value is minimized. (Being prepared for Publications)
(vi) Novel methodology for the optimization of weld-metal properties from flux ingredients was proposed. The methodology mitigates the limitations of the conventional welding flux development approach. (4 papers have appeared in peer review journals)
