Transcript of Man-Machine-Ratio

Effective use of machines and headcounts is essential in manufacturing for high return of investment from expensive resources in today’s competitive business environment. It is thus crucial to establish optimal man-machine ratio to gain high resource utilization and output. Man-Machine-Ratio Analysis The man-machine chart, or simochart, is a planning industrial graphically defining resources' activity (robots, operators, ...) at repetitive tasks. It is typically used to plan the activity of resources in large and medium series. The man to machine ratio is commonly used by organizations to calculate production output. It is a helpful way of correlating the amount of expenses and resources put into an investment versus the return. Usage As schedules conventional type Gantt or PERT, it allows you to adjust the industrial capacity (resources, robots, operators, etc.) Depending on the desired rate of production, provide or verify the time of cycle. In a study of industrial process, it is therefore necessary to make man-machines charts. They allow in manufacturing: To deduct the time of cycle from it in stabilized. To adjust the industrial ability at the desired production rate. To check that the actual facilities correspond to forecasts. This representation has become a universal support for all industrial players such as suppliers of machinery, maintenance, automation or mechanics.  Why plan for headcount?  to support customer requirements  to determine factory capability to support near term/future demands MMR PROCESS observe production activities breakdown activities into elements validate duration to perform activities through time and motion studies summarize data and present to management for approval MMR ELEMENTS  Activities
 Duration
 Frequency
 Available time (per shift)
