Please do not use computer program. It is only necessary to formulate the problem. Formulation steps are important to me. I will be glad if you solve with handwriting. URGENT.

1. A certain paint can be produced using four different production processes. The processing cost of cach liter in any of the four available processes, the maximum capacity of each process, and the setup costs are given in below table. Assume that a daily demand of 45,000 L must be fulfilled. At least two processes must be use for paint production Process and 3 must be taken simultaneously at the same time) or not taken at all. Formulate the problem as an integer programming model to determine the daily production schedule in order to minimize total costs Process Setup Processing Capacity C Cat (5/1) (L) 20000 17000 37000 500 P2 P3 P4 1000 0.5 0.3 02 600 33000
