A precast concrete façade production company supplies building contractors A, B, C and D. with units of precast facades to their construction projects. Contractor A orders 7 units every 4 days: B orders every 5 days but the size of its order varies according to the following table: C orders 5 units whenever it orders, but the interval between successive orders changes based on to the following table as well: Size of B's order (units) 5 7 9 11 Probability 0.2 0.3 0.3 0.2 Size of D's order (units) 3 6 9 12 Probability 0.1 0.2 Interval of C's order (days) 0.4 0.3 3 4 Contractor D orders concrete with varying size as well as varying interval, according to the following table: 5 6 Interval of D's order (days) 2 3 4 5 Probability 0.1 0.4 0.3 0.2 53 Probability Conduct a simulation exercise for 25 days demand for precast concrete facades commencing from an initial day when all the four building contractors order concrete. Based on the simulation results, what is the estimated mean demand for precast facades per day? Assumptions made: Random numbers are assumed to start from 00, 01.02........ 99.
