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,
8 ], }; d1 n8 f' I 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.
1 `0 p0 M$ J- D Loads are processed by each operator for the following time:: n" p* ~# s+ e, v/ h8 {# A
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
" n, z1 R* Z5 E% h 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.
: ~8 H3 a9 a. c# G- u8 c Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' M9 ?, ^7 s$ T" v
Send 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.: U( x j7 K, I. B9 d- U
* V$ `, O2 `. V3 c# ~
问题:) Z) j2 j; T. k% {5 e$ H/ m
After running the model for 10,000 days, what was the average number of loads in each process?, {) d5 C4 k) N" P
