Question 1: Process Efficiency Calculation "A manufacturing process has a cycle time of 20 minutes, with 3 workers operating simultaneously. The output rate is 12 units per hour. Calculate the process efficiency." Answer: Step 1: Determine the theoretical maximum output per hour. - Since each unit takes 20 minutes, in 60 minutes, one worker can produce 3 units (60 / 20). - With 3 workers, maximum capacity per hour = 3 workers × 3 units = 9 units. Step 2: Actual output is 12 units per hour, which exceeds the theoretical maximum. This indicates an inconsistency, suggesting a need to verify data. Alternative approach: - Given process cycle time and output, calculate efficiency. - Efficiency = (Actual output rate / Theoretical maximum output rate) × 100 - Theoretical maximum output rate: Number of units per hour based on cycle time for a single unit: - 60 minutes / 20 minutes = 3 units per worker per hour. - Total capacity with 3 workers: 3 workers × 3 units = 9 units/hour. - Since actual output is 12 units/hour, which exceeds capacity, perhaps the data implies overlapping shifts or parallel processes. Conclusion: Under typical circumstances, efficiency is calculated as: Efficiency = (Actual output per hour / Theoretical maximum output per hour) × 100 Given the data inconsistency, students should verify inputs, but the key takeaway is understanding how to relate cycle time, workforce, and output. --- Question 2: EOQ Calculation "A company faces an annual demand of 10,000 units. The ordering cost per order is $50, and the holding cost per unit per year is $2. Calculate the Economic Order Quantity (EOQ)." Answer: Step 1: Recall the EOQ formula: EOQ = sqrt[(2 × D × S) / H] Where: - D = Annual demand = 10,000 units - S = Ordering cost = $50 - H = Holding cost per unit per year = $2 Step 2: Plug in the values: EOQ = sqrt[(2 × 10,000 × 50) / 2] = sqrt[(1,000,000) / 2] = sqrt[500,000] ≈ 707.11 units Conclusion: The optimal order quantity is approximately 707 units. --- Question 3: Capacity Constraint Identification "A factory has a maximum capacity of producing 500 units per day. The current demand forecast is 600 units per day. What strategies can be employed to meet this demand?" Answer: Identifying the capacity constraint: The factory cannot meet demand without adjustments. Potential strategies include: - Increase Capacity: - Add additional shifts or overtime. - Invest in faster machinery or automation. - Expand facilities. - Adjust Demand: - Implement demand management strategies like pricing discounts or promotions during off-peak times. - Prioritize orders or segment customers based on capacity. - Process Improvements: - Lean manufacturing techniques to reduce waste and cycle times. - Streamline workflows to increase throughput. - Outsource or subcontract: - Collaborate with external suppliers to fulfill excess demand. Key takeaway: Combining capacity enhancement with demand management often yields the best results. --- Tips for Excelling in Operations Management Midterms Beyond knowing the right answers, strategic preparation is critical.
