This elapsed time includes the transport time, machine cycle time, waiting in machine queue or buffer stand, and the load – unload time. All time that it takes to cycle the pallet is captured and reported. Pallet Flow Time Performance Monitoring Machine Cycle Time The Machine Cycle Time is a display of the observed cycle times at the machines. These cycles are the elapsed time from a cycle start to cycle end.

Results of SAIL Increase machine utilization and throughput from 60% to 80% Add 1000 hours of machine hours per man per year. Case Study Large Midwestern Corporation Problem They wanted to determine the impact of unallocated burden on manufacturing cost. Results of SAIL SAIL’s cost model allowed for a planned cost that is adjusted using efficiency to determine an actual manufacturing cost Case Study Thermoking Corporation Problem Machine utilization and Throughput was not at maximum level. Results of SAIL Operators who were used to 50-70 parts per shift were now producing 400 parts per shift. Machine utilization was now at 85%. Case Study Southern Manufacturer Problem Had a two machine system, with room for expansion, but hesitated because of low machine utilization. Results of SAIL Machine utilization reached 85% They now could easily justify the third machine expansion. A Management System that Starts with the Factory Order System To Generate an Optimal Shift-by-Shift Schedule That downloads Instructions to the Cell Control For Execution and Operation While Monitoring and Broadcasting Performance Target Users/Applications SAIL is a tool designed for manufacturers with flexible machining systems, automated machine cells, and automated handling systems. Three days of training are recommended for use of this software. Additional training is required to integrate SAIL to other computer systems such as factory systems and cell control computers. 1610 S.
