This paper studies the performance of automatic production lines with the fixed number and fixed ordering of working processes. In our models, it is supposed that every stage has an exponential distribution of time between failures and a logarithmic normal distribution of repair time. We propose some procedures to estimate the influence of configuration parameters on the line production rate with the use of GPSS simulation method. The configuration parameters to be studied are capacities of buffer storages, productive performances of stages, a way of allocating buffer storages, and forms of production line. We consider serial production lines and production lines with loops as a form of production line, and deal with individual buffer storages (buffer storages allocated to each stage) and common buffer storages as a way of allocating buffer storages. First, we compare the line production rate of a serial production line with individual buffer storages and that of a serial production line with a common buffer storage. Second, we study the relationship between the line production rate and the total capacity of buffer storages. Finally, we compare the line production rate of a serial production line and that of a production line with loops at various productive performances of stages and various capacities of buffer storages.
