: For each of the situations a through e below, perform $30$ simulations and report the identified metrics in the table below. Note: overall mean cycle time through the process from the time it enters WS$1$ to the time it leaves WS$3.$ This is computed by adding the overall mean cycle times through the internal buffers, the Buffers added between Work Stations $($if any$),$ and the mean working times at the Work Stations.

a$.$ Consider the SimQuick model base case as shown above. Note that the $$Working time$$ for each Work Station is Uni$(5,15).$

b$.$ Consider the original model, and change the working time at each Work Station to

Uni$(9,11).$ Note that the new working times have the same mean but a smaller variance.

c$.$ Consider the original model, using the reduced variance distribution from part b on WS$2$

only.

d$.$ For the original model, add a Buffer between WS$1$ and WS$2$ and another Buffer between

WS$2$ and WS$3($with no initial inventory$).$ Set the capacity of both Buffers $3.$

e$.$ For the original model, add a Buffer between WS$1$ and WS$2$ and another Buffer between

WS$2$ and WS$3($with no initial inventory$).$ Set the capacity of both Buffers $9.$
