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,
' _1 z/ ?& p& Y- _0 t6 ~ 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.$ E; q5 a; p3 [+ \( k! }! b+ ^
Loads are processed by each operator for the following time:
4 _3 O; s* t4 ~: d0 h1 k/ [ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.9 c# A# a2 H- s' L/ j4 `- }- A$ Z5 k% 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.
, Z9 Y d2 M) N+ b Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 ~/ a3 ^. F" l$ q% g- XSend 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. V7 L7 c- R* Z+ Q

After running the model for 10,000 days, what was the average number of loads in each process?
