The Determination of Optimum Process Mean in a Single-Stage Production System: A Markovian Approach

This paper studies a production system where products are produced continuously and whose specification limits are specified for screening inspection. This paper considers different costs associated with a quality characteristic that falls below a lower screening limit, or above an upper screening limit. Due to these different costs, the expected total profit will greatly depend on the process parameters, especially the process mean. Therefore, this paper develops a Markovian-based model for determining optimum process parameters in a single-stage production system. The proposed model was illustrated through a numerical example, and sensitivity analysis was performed
