刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,7 b" }) A- \7 T0 j
Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.
; r, ~; c2 C a% ^! [: F Loads are processed by each operator for the following time:! Y* n1 l& j% X5 ]: l* t0 j# l% P
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' i3 m2 [) H8 Y5 N
Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.
- O* Q3 g+ ^) `! w* g+ F4 u6 W Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Z5 W& \& K; ^+ x$ M7 QSend loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.
3 Y1 T1 d& Q* U6 K# ~5 m* }, }# u0 J) _! @4 R& I
问题:
