TOTAL TIME: 3 HOURS (1) Question 1 is compulsory.
(2) Attempt any four from the remaining questions.
(3) Assume data wherever required.
(4) Figures to the right indicate full marks. 1(a) Briefly explain the steps in simulation study(10 marks) 1(b) Give an example of each type of model and state the one that leads to simulation.(10 marks) 2(a) Describe queuing system. What is the condition that leads to stability? (10 marks) 2(b) Write event scheduling algorithm. Give the system snapshot at time t.(10 marks) 3(a) Discuss various costs that are involved in inventory system.
