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,
, K9 o2 z! H7 }! ^9 ] 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.+ l$ F6 N3 z5 E& e( r& W+ a; ~
Loads are processed by each operator for the following time:
8 P8 b1 i. u! f9 m Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
2 K+ l' U. M7 `" V) L5 K* O7 S9 d 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.
9 g0 Y$ W* z- k- M Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& t- X* t; E# N2 _
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.: D# a% V8 m) W0 ~8 j
- e; F! `+ t0 H5 Q问题:4 M9 p( o+ J7 D3 z3 R/ r; P
After running the model for 10,000 days, what was the average number of loads in each process?) O' v+ \( a# S0 F" \
1 J) m9 h( H: ^7 [
