Basic Manufacturing Process with 2 Job Types +
Inspection
Time between job arrivals at a machining station is exponentially distributed with mean 4.4 minutes.
There are 2 types of jobs to be processed 30% of which is Type 1 and, 70% are of Type 2. Processing
times are exponentially distributed. Mean processing time for Type 1 is 4.8 minutes, for Type 2 it is
2.5 minutes.
After the job is processed, they go through an inspection process with one single inspector and an
inspection time with triangular distribution (1,2,3.5). Inspector decides whether the part is good
enough, scrap or should be reworked. 80% of the parts produced is good, 10 % is scrap and the rest
needs rework.
Rework is done by the same manufacturing machine. The priority among the parts will be Part1 first,
part2 second and reworks of both type comes later. Rework time is normally distributed with mean 2
minutes and 0,2 std dev.
Simulate the system for one 8-hour day.

A new electronic component for aircraft is tested to withstand temperatures as low as -50°F. One engineer suggests that the device cannot actually stand temperatures that low. What are the Type I and Type II errors?
Type I: The device CAN NOT withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN.Type II: The device CAN withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN NOT.
Type I: The device CAN withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN NOT.Type II: The device CAN NOT withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN.
