I have built the model. Need help with

Interarrival times will drop from 9.1 minutes (exponentially distributed) to 4 minutes (still exponentially distributed). You know from Part A that youre docks are heavily utilized, and therefore the increased traffic will not likely be possible given the current capacity. Your job is to test three alternatives and recommend which is best:

Alternative 1:Buy new unloading equipment that will increase the throughput at each dock (i.e. decrease the unloading times) to the following:

Dock	Distribution	Minimum	Mode	Maximum
1	Triangular	20	23	25
2	Triangular	18	21	23
3	Triangular	17	20	22

The cost of leasing the new equipment will be $300 per day, and youll need one for each dock.

Alternative 3:Manage the arrival schedule so that trucks arrive at the same rate, but at specific times (i.e. the interarrival rate is a constant 4 minutes, vs. exponentially distributedthus removing the variability).
