| Abstract | ||
| from raw materials and semi products pass through many tasks, these tasks differ in numbers and complexity with the product differece, design specifications, and also the production system type. Tasks time differential cause work in process inventory problem or idle time problem in some workstations of the line. These problems affect efficiency of the line and increase the total production cost. In this research, computer aided visual monitoring system designs and builds for monitoring the flow of materials and determine location and quantity of work in process inventory in the production line to minimize this problems by rearrange workstations of the line and connecting the critical stations that materials blocked in it with extra stations in parallel to minimize the work in process inventory among workstations of the line possiblely to minimum level to increase the flow of materials and then to the increases efficiency of the line .The suggested system applied at the state company for electrical industries on the stator production line where the system uses for monitoring & studying flow of materials between its workstations. The researcher depends on company data&his grouping data. Monitoring &studying the current workstations arrangement shows low efficiency (50.96%) and low daily production rate (270 unite/day), so arrange workstations of the line by suggested arrangement, can increase the line efficiency to (77.96%)and also can increase daily production rate to (540unite/day) by arrange the line workstations by suggested arrange | ||
