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,
* b+ f2 M5 y( [2 _; 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.
& p0 O' c# W6 Z, r Loads are processed by each operator for the following time:
' P1 h7 x! b z9 z5 g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 _5 Z7 Y8 O8 X4 Y3 y2 k 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.# g, W: r! ?( w! a4 Z$ t7 R9 q' d
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: y, Q; q+ f/ c' h4 \5 bSend 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.+ [$ Y) m/ K- D- z7 c
: b) s) z3 \5 B; g1 ?( s. M! ~: O* d
问题:2 ^: @! ~2 J2 G6 `; @7 K z. u# n
After running the model for 10,000 days, what was the average number of loads in each process?# P7 L2 G% R0 ~/ H! D' R: p
$ {4 L+ R+ U) _7 h& p: C1 C不胜感激! |
