Modeling and simulation is the use of models as a basis for simulations to develop data utilized for managerial or technical decision making. Lead time for a stock item is normally distributed with a mean of 7 days and a standard deviation of 3 days. Daily demand is distributed as follows: Daily Demand Probability Determine the lead-time demand for 25 order cycles. (Round off lead time to the closest integer during the simulation and, if a negative value results, Give it a lead time of zero.) Generate the hundred random numbers by using arena scheme then check these . 1 2 3 4 0.35 0.22 0.19 0.05 0.09 . numbers are uniformly distributed and have any correlation between these numbers. You will consider seed square of your roll number. By using above generated random numbers to compute the exp (/2)dx by using the Monte Carlos simulation. Where you will consider the value of a is second digit and b is first digit of your roll number. B. C.
