SECTION A
Attempt any TWO question.
Why is it necessary to analyze the simulation output. Explain different estimation method which are used in simulatiom output analysis.
Consider that a machine tool in a manufacturing shop is turning out parts at the rate of two every 5 minutes. As they are finished, the parts go to an inspector, who takes 5±2 minutes to examine each one and reject about 15% of the parts. Now develop a block diagram and write the code for simulating the above problem using GPSS, and also explain the function of each block used in the block diagram in detail.
Explain the independenceand uniformity property of random number. For the following sample of random numbers, perform test for independence using K-S test. (D0.05,10 = 0.41)
0.35, 0.77, 0.12, 0.33, 0.88, 0.45, 0.19, 0.25, 0.91, 0.54
