This document contains questions that appear to be from an examination for an 8th semester engineering degree in System Modeling and Simulation. It includes 10 questions divided into two parts (A and B). Part A covers topics like circumstances for using simulation, steps in a simulation study, queue modeling, and random number generation. Part B addresses additional modeling and analysis topics such as random variate generation techniques, simulation table construction, and goodness of fit tests. The document provides context for summarizing a technical examination in the field of systems modeling and simulation.

c. One company uses 6 trucks of haul manganese ore from kolar to its industry. There are two
loaders, to load each truck. After loading, a truck moves to the weighing scale to be
weighed. The queue discipline is FIFO. When it is weighed, a truck travels to the industry
and returns to the loader queue. The distribution of loading time, weighing time and travel
time are as follows:
Loading time: 10 5 5 10 15 10 10
Weigh time: T2 t2 L2 t6 L2 t6
Travel time: 60 100 40 40 80
Depict the simulation table and estimate the loader and scale utilization. Assume 5 trucks are
at the loaders and one is at the scale, at time '0'. Stopping time Tp = 76 min. (10 Marks)
a. Explain discrete random variable and continuous random variable with example. (08 Marks)
b. Explain the following discrete distribution:
i) Binomial distribution ii) Poisson distribution. (06 Marks)
