Document Summary
Then evaluate the remaining data with the control chart. Compute the standard deviation of forecast errors using the first 8 months: determine 2s control limits: s= mse=6. 46. 0 2s = 0 2(6. 46) = 12. 92 to +12. 92. Operations management is concerned with designing, assessing, improving and managing the processes with the goal of matching supply and demand in the most cost effective way. Key objectives : - designing the process - assessing the process - improving the process - Process flow diagram = a method to describe tasks, flows, etc. in an operating systems. It is a graphical way to show how inputs are transferred to output, or how the service is delivered. Decide about the level of details you want to include in the process. Determine flow unit (i. e. car in carwash process, patient in heath process) > throughput time is the amount of time a flow unit spends in the process (including waiting time).
