Exercise 18: For each of the situations a through e below, perform 30 simulations and repmt the overall mean throughput (i.e., the overall mean @ inventory of Buffer: Finished Goods). Also repelt the overall mean cycle time through the process from the time it enters WSl to the time it leaves W83. 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 described above. Note that the \"Working time\" for each Work Station is Uni(5,15). b. Consider the original model, changing 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
