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 i* y7 q0 M6 x4 N/ Z( 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.
8 `# ]+ H8 e& \/ W( c9 n Loads are processed by each operator for the following time:, M7 m: Z+ y: ?) l
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.) ^1 L. J) h! m" |, i. _
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.
0 ]6 G' b( X: A7 w, | Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; d- o# m% j5 R' G2 z, \) L6 SSend 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.
