This thesis investigates the interactions of several characteristics of serial production lines that contribute to production line performance. A full factorial experimental design of computerized simulations is conducted with three levels of downtime, four levels of variability, three levels of line length, three levels of constraint location, three levels of work-in-process, and six levels of protective capacity. This study enlarges upon recent four-workstation investigations and extends the knowledge to longer production lines. Some generalizations for the amount and location of protective capacity are drawn from the results, as a guide for process improvements and new production line design. An approximating regression model is constructed for prediction of cycle time outcomes with various values of contributing factors.
