The decisions to make (i.e., decision variables) are which task should be assigned to what workstation. What are the constraints? Be specific and write in an LP format (so be sure you put them in a generic way; half of the credits if not formulate using generic expressions). Hint: Decision variables Xij (task i got assigned to jth workstation): i=A~D element; j=1~3 (to indicate 1st, 2nd, 3rd station respectively)

Constraints: 1. precedence constraint:

2. cycle time constraint:

3. each task is assigned to 1 and only 1 workstation):
