The following data are known: 1. Exploded view of the laptop; 2. Bill of Materials (BOM); 3. Precedence graph; 4. End of life value for each laptop component; 5. The task times. <Labs: Disassembly strategies> Exercise 1: laptop case The laptop in the figure has to be disassembled to recover the maximum value from the end of life product. The following data are known: 1. Exploded view of the laptop; 2. Bill of Materials (BOM); 3. Precedence graph; 4. End of life value for each laptop component; 5. The task times. Figure 3 <Labs: Disassembly strategies> Exercise 1: laptop case The task times are reported in the following table.

Formulate the problem of finding the best disassembly level to maximize the profit, without considering set up times, knowing that the fixed cost of disassembly is 1 Euro/tu. Solve the problem and suggest a feasible and optimal sequence. B. Formulate the problem of finding the best disassembly sequence, considering in input a given disassembly level and taking into consideration the set-up times reported below. C. Solve the joint problem. D. Compare the two solutions. STT…
