 Show CHAPTER 2 2.1 If the opening inventory is 400 units, demand is 900 units, and production is 700 units, what will be the ending inventory? Ending inventory = opening inventory + production – demand = 400 + 700 – 900 = 200 units 2.2. A company wants to produce 500 units over the next 3 months at a uniform rate. The months have 19, 20, and 21 working days, respective! On the average, how much should the company produce each day to level production? Total Production = 500 units Total working days = 19 + 20 + 21 = 60 days Average daily production = 500 / 60 = 8.33 Answer. Average daily production = 8.3 units 2.3. A company plans to produce 25,000 units in a 3-month period. The months have 22, 21, and 20 working days respectively. What should the average daily production be? Total Production; = 25,000 units Total working days = 22 + 21 + 20 = 63 days Average daily production = 25,000 / 63 = 396.8 units 2.4. In problem 2.2, how much will be produced in each of 3 Months? Month 1 = working days * production / day = 19 days * 8.33 units = 158 Month 2 = 20 days * 8.33 units = 166 Month 3 = 21 days * 8.33 units = 174 2.5. In problem 2.3, how much will be produced in each of the 3 months? Month 1 = working days * production / day = 22 days * 396.8 units = 8729.6 units Month 2 = 21 days * 396.8 units = 8332.8 units Month 3 = 20 days * 396.8 units = 7936 units 2.6. A production line is to run at 1000 units per month. Sales are forecast as shown in the following. Calculate the expected period-end inventory. The opening inventory is 600 units. All periods have the same number of working days. Operations Management, 11e (Krajewski et al.)
