It is the purpose of this paper to discuss 3M' s 'Optimized Operations' program and evaluate the potential of this program as a tool to reduce inventories. This project is not a design project or a process understanding project; therefore, little time is spent discussing the specifics of the equipment modifications. In addition, no environmental or safety issues were considered. The Just-In-Time manufacturing concepts of economic order quantity and setup reduction were applied to a nonwoven laminator in an attempt to reduce the in-process inventory between the laminator and the next step in the manufacturing process. The initial step was to determine the current setup cost and average inventories. Following that, an equipment setup was videotaped. The resulting video tape was analyzed, and the setup broken down into elements. These elements were timed and identified as being either internal or external to the changeover. By applying the setup reduction concepts of eliminating nuts and bolts, eliminating adjustments by using block gauges and templates, and eliminating or moving changeover elements external to the changeover, eleven equipment modifications were identified and implemented. The application of the Economic Order Quantity (EOQ's) concept, along with efforts to reduce setup costs, resulted in a 55% ($155,081-$70,340) reduction in average monthly inventory.
