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,
3 p7 O) u" |: D$ e 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.* w% [# N; w; j% e' z( q# W
Loads are processed by each operator for the following time:' j; O0 J/ [! `, {( u% l
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- ?& v. I: P L% S 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.
4 N1 E, Y) S/ {# S Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; }/ r* ~- ^5 j) d4 w4 F
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.) r4 ] P4 y( e u. O Y/ u V- [
2 _6 k5 e0 i) y# ^0 M7 l
问题:
