$4)(20\%)$ Develop a Simio simulation to analyze the scenario given in problem $2\mathrm{.}23.$ Consider three variability cases for the coefficient of variation: $0\mathrm{.}10$ and $0\mathrm{.}3($implying a Normal Distribution$).$ For each of the different variation cases, determine the right$-$size of buffer $($include the two baseline cases where buffer size is $=0$ and is infinite, in addition to scenarios in$-$between$)$ to put between each workstation. Use an arrival rate of Exponential$(50).$ Run your models for at least ten replications of $40$ hours in order to generate valid statistics. Assume the time unit for operation time and cycle time is minutes. Be sure to state any assumptions you make. Based on your analysis, provide a recommendation for each variability case and your supporting rationale. Submit screenshots of your simulation model in your report, plus upload your Simio model with your assignment. Submitting the simulation results without discussion will result in zero points $..$ discuss what you find in your analysis!
