Abstract

Since footwear industry is playing an important role in the society and is also vital for overall industrial growth, it is necessary that the footwear industry may perform well. Therefore, the main concern of an industry is to maintain system performance measures such as reliability, excepted up time, busy period of repairmen etc. to achieve high profit and productivity of the system. Present paper deals with the analysis of a single unit footwear machine having electrical/mechanical faults. These faults are further bifurcated into minor, major and neglected faults. Here two stochastic models of footwear machine have been discussed for comparison thereof. In model-1, all neglected faults revolve to be major faults due to delay in maintenance whereas in model-2, neglected faults sorted out automatically under preventive maintenance. However, in both the models, minor faults are assumed as repairable and major faults are non-repairable. In both the models, various measures of system effectiveness such as MTSF, Reliability, Expected up time and busy period of serviceman have been obtained using Semi Markov Process and Regenerative Point Technique. Finally, the comparison of both models with respect to reliability and profit has been carried out using graphs and numerical calculations. Conclusions are drawn on the basis of graphs, which may be helpful for the maintenance team of the footwear machine.
