Operations and supply chain management

What I need is atucally just results/correct answers so I can compare with my own calculations.

Thanks in advance!

Exercise 2 (30 percent) HE-VA produces a great variety of agricultural implements, such as plows, harrows, seeders, etc. The company wants to setup an aggregated plan and the aggregated product of this plan is denoted as a tool". 244 hours of working time are required for the production of one "tool. In addition, materials worth 38500 DKK are required as well in the production of one tool. The selling price of a tool is 172300 DKK and forecasted demand for the next 12 months is: Demand forecast (tools) Month 152 119 174 The workers are paid 305 DKK per hour and each worker works 160 hours each month. In other words, one worker costs 48800 DKK per month. Working overtime is not possible in questions 1-6. Each worker can be hired as a part-time worker. Hence, the necessary calculations do not involve integers. The initial inventory is 85 tools, and at the end of period 12 there must be 85 tools in the inventory. The holding cost is 10000 DKK per tool per month. HE-VA employs 140 workers at the start of period 1, and they can hire additional or fire existing employees. The cost of hiring an additional employee or firing an existing employee is 15000DKK Again, the necessary calculations do not involve integers. Stockouts are not possible in the aggregated plan, and it is not possible to use subcontractors. 1. Create a level production plan without using overtime. Report production, inventory and number of employed workers for each month. 2. Calculate cost for the whole year for the aggregated plan from question 1 disaggregated into the following categories: hiring cost, firing cost, wage cost, inventory cost and material cost. Calculate the total cost and the total revenue. 3. Create a chase production plan without using overtime. Report production, inventory and number of employed workers for each month. 4. Calculate cost for the whole year for the aggregated plan from question 3 disaggregated into the following categories: hiring cost, firing cost, wage cost, inventory cost and material cost. Calculate the total cost and the total revenue. 5. Create a cost minimizing production plan without using overtime. Report production, inventory and number of employed workers for each month. 6. Calculate cost for the whole year for the aggregated plan from question 5 disaggregated into the following categories: hiring cost, firing cost, wage cost, inventory cost and material cost. Calculate the total cost and the total revenue. The union now allows for the possibility of using overtime. The additional overtime cost of one hour of overtime is 40 DKK per hour. Hence, if the company decides to ask a worker to work one hour of overtime then the total labor cost of this hour is 345 DKK. A worker is not allowed to work more than 16 hours as overtime per month. 7. Create a cost minimizing production plan allowing for the use of overtime. Report production, inventory, number of employed workers and total overtime for each month. Calculate the total cost and the total revenue. 8. It turns out that the inventory at HE-VA has a capacity limit of 85 tools. Create a cost minimizing production plan allowing for the use of overtime that does not violate this capacity limit. Calculate cost for the whole year for the aggregated plan disaggregated into the following categories: hiring cost, firing cost, wage cost, inventory cost and material cost. Calculate the total cost and the total revenue. 9. What amount of money would HE-VA be willing to pay for an expansion of the inventory capacity with one units, i.e. an expansion of the capacity from 85 to 86 tools. Explain your answer.
