The project manager in charge of the project is trying to construct an integrated water station to determine the starting lineup for the work implementation team. There are seven staff to choose from and each of them (based on a three-level scale) is categorized based on different skills as shown in the following table (the higher the rating is better). The table also shows the positions each team can play (O operating, P production, M - maintenance). team position Civil work Mech. Elec. work Overall work 1 2 M 2 O,P P,M O,P P,M O,P 3 2 3 4 1 3 1 3 1 3. 7 3. 1 1. Write the constraint that represents " at least three of the starting group must be %3D able to do operating". that represents " The average civil work skills must be at least 2". that represents " team 3 and 6 cannot both start". that represents " If team1 starts, then team 4 and 5 must also 2. Write the constraint 3. Write the constraint 4. Write the constraint start". 5. Write the constraint that represents " Either team 2 or 3 must start".
