Question: (a) Repeat Exercise for the PR scheduling rule.
(b) Repeat Exercise for the SIO scheduling rule.
(c) Compare the minimum required number of workers for each scheduling rule: FIFO, versus PR, versus SIO.
Exercise: In the job shop with FIFO rule, fmd the minimum number of workers needed at each station to avoid bottlenecks. A bottleneck occurs when average queue lengths at a station increase steadily over time. (Do not confuse increasing average queue length due to an inadequate number of servers with increasing average queue length due to initialization bias. In the former case, average queue length continues to increase indefinitely and server utilization is 1.0. In the latter case, average queue length eventually levels off and server utilization is less than l.) Report on utilization of workers and total time it takes for a job to get through the job shop, by type and over all types.
