The worst considered type of hold back within a manufacturing facility is an unexpected breakdown of machinery. Such breakdowns that would typically cost the most due to time lost during production. This report will explore the possibility of utilizing a mix of both Non-­‐linear & Linear programing in excel to develop a basic staffing model to help develop an optimal preventive maintenance plan that will minimize breakdowns and the costs associated with them. The established model can help with the prevention of future failures within different equipment and minimize costs to allow for an increase in profit.
