Modeling of Production Loss for Assembly Systems during the Warming-period considering Bernoulli Machines and Finite Buffers

Abstract

Production loss characterizes the difference between the expected horizon and the actual system performance. In this paper, an analytical method is proposed to model the production loss for assembly systems during the warming-period considering Bernoulli machines and finite buffers. First, the modeling of the assembly system is performed based on the transient analysis. Second, dynamic states of machines and buffers are formulated to characterize the production loss for assembly systems. At last, the impact of system layouts, machine reliabilities, and buffer capacities on production loss are numerically investigated in case studies. The results indicate that this method can evaluate the production loss for assembly systems during the warming-period, which exhibits the potential to design or manage more complex assembly systems.
