Case Study on STONEHAVEN INC. QUESTIONS: Part A: For this part of the analysis, consider each department in the Gdnask factory “in isolation” – that is, when doing the calculations, imagine for the moment that the rest of the production system has no impact on the department you are considering. For the purposes of these calculations, material handling times may be assumed to be negligible, and you can ignore variability in processing times. Please be sure to state your assumptions. 1. For the typical 100-pair batch, what is the daily capacity and flow time within each of the following departments? a. Cutting b. Stitching c. Lasting 2. If the batch size were reduced to 10 pairs, what would be the daily capacity and flow time within each of the following departments? a. Cutting b. Stitching c. Lasting Part B: Now consider the factory as a system, and take into account interactions between the departments. Please be sure to state your assumptions. 3. Assuming production is done in 100-pair batches, what is the factory’s daily capacity? 4. What is the total flow time for a 100-pair batch? Part C: 5. How would you go about deciding on the appropriate batch size for the Stonehaven factory? What factors would you consider? How do they interrelate? 6. Focus only on your highest priorities for improving the production process at the Stonehaven’s Gdansk factory (be specific). Explain why they are important. What actions do you recommend?
