7. The manager at Ormonde Inc. collected the value stream mapping data from the plant's most problematic manufacturing cell that fabricates parts for washing machines. This data is shown in Table 1. Using this data, calculate the current state performance of the cell and answer the following questions. Overall Process Attributes Average demand: 540/day Batch size: 20 Number of shifts per day: 3 Availability: 8 hours per shift with a 45 minute lunch break Process Step 1 Cutting Cycle time-115seconds Setup time-3minutes Up time-100% Operators 1 WIP-400 units (before Cutting) Process Step 2 Bending Cycle time 250 seconds Process Step 3 Punching Supplier Information Information Flow Setup tim-5 minutes Up time-97% Operators 2 WIP-500 units (before Bending) Cycle time-140 seconds Setup time-none Up time 100% Operators 1 WIP-200 units (Before Punching) WIP 1,000 units (After Punching) One shipment of 2,700 units each week All communications with customer are electronic There is a weekly order release to Cutting All material is pushed a. What is the cell's current inventory level? The cell's current inventory level is parts. (Enter your response as a whole number.) b. What is the takt time for this manufacturing cell? The takt time is minutes (The cell's takt time is the rate at which the cell must produce units in order to match demand. It can be calculated as a ratio of the time available in a day (daily availability) and daily demand of parts). (Enter your response rounded to two decimal places.) c. What is the production lead time at each process in the manufacturing cell? Complete the table (Enter your responses rounded to two decimal places.) Interval Before Cutting Between Cutting and Bending Lead time days days Between Bending and Punching days After Punching days d. What is the total processing time of this manufacturing cell? The cell's total processing time is seconds. (Enter your response as a whole number.) e. What is the capacity of this manufacturing cell? The cell's capacity is units. (Enter your response rounded to the nearest whole number)
