4.1 Calculate the Minimum Cost Capacity-Feasible (MCCF) and the Cycle Time of the production line that assembles PM-B. Calculate the cost capacity and cycle time for each workstation first. Show the calculations of Workstation 1 and 4. Fill out the following table (Table 8).

4.2 The target cycle time for the assembly line is CT=20 days. The different options to achieve the target is give in Table 9. Find the cheapest options to achieve the targeted cycle time by filling out the Table 9 and Table 10. Calculate the cost and the cycle time of the best option.

To assemble PM-B in the factory in Stuttgart, it requires four steps performed in four workstations as depicted below. The assembly line has throughput target of three jobs per day and 1 machine can handle 1 job. c = 1.00 2 4 Table 7 The property values corresponding to the workstations Workstation Setup cost Unit cost (000 Eur) (000 Eur) (days) 20 2.5 1.25 1.75 3 10 18 Table 8 MCCP and cost of assembly line PM-B Workst Number Number of Utiliza Costs ation of Jobs Machines tion 000 ) (in ca?
