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,' S3 |: r$ N( v1 A
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 b! P- Y1 m% I- f Loads are processed by each operator for the following time:
, T/ q D; q- I, Q! K Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, [; N( H4 x- F0 ~' S l, B. X 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.: t1 H3 @; f+ Q9 n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: `2 `" Z4 T' B) s* Y/ i2 _
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.' Y9 n- h) v% J Q
