Candidates are required to give their answers in their own words as far as practicable.
Group A
Long Answer QuestionsAttempt any Two questions.
- 1Why it is necessary to analyze the simulation output. Explain different estimation methods which are used in simulation output analysis. [3+7]
- 2Consider 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 $5 \pm 2$ minutes to examine each one and rejects 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. [3+3+4]
