In this paper, we explore the problem of availability analysis for a specific assembly system inspired from a real case. Contrary to regular assembly systems, we consider a three-working-station case where we have two intermediate buffers. The flow of materials is discrete. Since availability rate is one of the most important performance indicators for any company, we aim at providing tools to calculate the underlying measure for the assembly systems studied here. We tackle the problem by both simulation and analytical models. We use discrete event approach to simulate model, while in analytical model, we utilize Markov chain to assess the availability. Finally, we evaluate the performance of analytical model by comparing it against the simulation model proposed in this paper.
