Abstract

To evaluate the task reliability of manufacturing equipments with many components, a short-time and long-time manufacturing process reliability model is proposed to fulfil this task. The short-time manufacturing process reliability model based on multiple regressions aims to eliminate the effect of datum error on product quality. The long-time manufacturing process reliability model studies reliability change mechanism over time by means of Markov chains. Reliability computing method is given by considering the general definition of task reliability. Proposed product quality characteristics oriented model applies to manufacturing equipment reliability evaluation which avoids discussing numerous components of manufacturing equipment and complex relationship between them. Finally, the case result indicates that the proposed model can get more accurate estimated value of manufacturing equipment task reliability. Keywords: manufacturing equipment; process reliability; product quality characteristics. Reference to this paper should be made as follows: Zhang, F-p., Wu, D., Zhang, T-g., Zhang, Q-y. and Yan, Y. (2016) ` for manufacturing equipments', Int. J. Internet Manufacturing and Services, Vol. 4, No. 2, pp.91­101. Biographical notes: Fa-ping Zhang holds a PhD and is an Associate Professor at Beijing Institute of Technology.
