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,
6 t% v+ s+ J4 F% L6 S. L 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.
; `6 k( O8 ?# l. y Loads are processed by each operator for the following time:
/ ]7 F$ }1 M) F- D Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 [ a& r) @9 e/ A2 z# ]
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.
" i0 J5 t! Z8 H* g2 A+ U2 x Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' k+ b2 ^, |- o/ T3 q1 j
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.
