Experimental Design for Buffer optimization of unreliable production system with transportation delay based on Salameh Model

Abstract The work reflects the study of a manufacturing system composed of a single unit production operating according to a just-in-time configuration, buffer and a constant demand. The production machine is submitted to preventive maintenance actions for each time T. In order to study the impact of the transportations durations constraints between the production unit and the warehouse and between the warehouse and the customer, we developed a mathematical model to determine the optimal just-in-time stock level S * which guarantees the minimisation of total average cost per unit time. A numerical example is presented to illustrate the results found.
