1 Process A certain paint can be produced using four different production processes. The processing cost of each 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 1 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 Setup Processing Capacity Cost (5) Cost (SL) (L) 20000 17000 37000 33000 P1 SOO 06 P2 000 1000 P3 05 03 0.2 Pa 000
