SAVING SCENARIO DATA XI. CLEARING SCENARIO DATA XII. TECHNICAL SUPPORT INTRODUCTION The following is the Installation Guide and User's Manual for the Forging Operation Planning Tool (Forging). The primary purpose of Forging is to determine if sufficient capacity is available (in terms of equipment) to satisfy the stated demand. The user can vary the following operating parameters to conduct "What-If" analysis: 1. The time period to simulate up to 360 days 2. The number of shifts per day, hours per shift, and crews per shift 3. The part numbers to be produced - Forging has the capability to handle up to four hundred (400) different part numbers 4. The consolidation period - the number of days to consolidate into one order 5. The unit sales price 6. The rework station 7. The furnace temperature 8. The furnace batch size 9. The type of station used to process the parts (these stations can be either manual or automatic) - Forging has the capability to handle up to fifty (60) different station types 10. The station capacity 11. The operating sequence for each part type - this defines the sequence of operations (by station) for each part type up to sixty (80) processes 12. The cycle time efficiency factor by part number and process 13. The cycle time by part number and process 14. The setup time by part number and process 15. The rework rate by part number and process 16. The Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) for each station - this is referred to as "Failure, Repair Times" in the user interface screen. FOPT uses an exponential distribution when assigning a value for MTBF and a normal distribution when assigning MTTR. 17. The preventive maintenance schedule The user can run Forging with the specified parameters and view the results. All output units in this system will be in minutes. The results are divided into three categories: 1. Throughput in terms of units and dollars 2. The simulated production by part number and time interval 2. Resource (or station) utilization, which would include the percent of time the resource was busy, idle, inactive, or down 4. Station queue sizes Forging can be used as often as is needed, based on the business/operating environment. This will allow the analyst to evaluate future business and operating scenarios to optimize the utilization and throughput of the Process Area.
