1. Use the MIP model to obtain 6 different constrain types related to department A by using the table if the diminutions of facility are 50m*150m. 2. One of the requirements is to make the center of department B at the center of the facility, write a constrain(s) to achieve this requirement. 3. If the length of the facility is unknow, and you plan to minimize it, what you will do. I Department Area (m) 2500 1000 2000 1500 A B Tulalt C D Minimum and maximum length Minimum and maximum width (70,100) (30,70) (30,90) (50,70) (20,40) (10,40) (30,60) (30,40)
