2. If the batch size were reduced to 10 pairs, what would be the daily capacity (in batches and in pairs of shoes), the batch cycle time, and the average manufacturing throughput time per batch (in minutes) within each of the following departments? A. Cutting Capacity = 18.18 batches/day or 181.82 pairs/day Batch Cycle Time = 26.40 min/batch MTT = B. Stitching Capacity = 32 batches/day or 320 pairs/day Batch Cycle Time = 15.00 min/batch MTT = C. Lasting Capacity = 34.29 batches/day or 342.86 pairs/day Batch Cycle Time = 14 min/batch MTT = Time Available Daily (Min.) 480.00 Kitting Department Cutting Department Setup Time (Min.)
