Level Operation: Case
A level operation is a small company located in eastern Pennsylvania. It produces a variety of security devices and safes. The safes come under several different designs. Recently new customers have placed orders. For this the production manager is currently working on a production plan for the safes. She needs a plan for each day of the week. To support the production decision she pool out the forecasted demand for next five weeks. The level operation operates five days a week.
The best production quantity per cycle:
For Stephanie, producing in small lots allows her to minimize work-in-process inventory which translates to 'waste' in lean operations as well as maintaining flexibility. By analyzing the case, Stephanie has determined the sequence of production to be S7-S8-S9-S1-S2. Units demanded per week are provided by the demand forecast.
Assuming a five-day work week, the following weekly schedule should level the load across five weeks. Each row is arranged according to the sequence in which the products would be produced.
In order to determine daily production of safes, total weekly demand of each model was divided by 5, the number of days in each week. Demand for Models S7 and S2 was not evenly divisible by 5, as a result, additional units were scheduled to be produced with the production of additional units interspersed throughout the week in order to achieve nearly. Level production. Monday, Wednesday and Friday production levels differed from Tuesday and Thursday. Due to these differences, cycles and units produced per cycle were different for the 'Monday, Wednesday, Friday' grouping from the 'Tuesday, Thursday' grouping. Production per cycle for Monday, Wednesday and Friday.
Summary and Conclusion
The number of cycles was determined as the fewest number of cycles that contained 1 unit of the model with the lowest quantity requirements, which in this case was Model S9. Each daily production quantity was divided by 5 with Models S8 and S1 requiring additional units interspersed between cycles. The same strategy of determining cycles was used for the 'Tuesday, Thursday' grouping. The number of cycles was kept at 5 with additional units required of Models S7, S8, S1 and S2. Production Schedules for Models S8 and S1 were kept the same as the previous grouping. Changes in additional units were added for Models S7 and S2 with a focus on leveling production.
