I am performing reliability analysis.  I have two types of data:

1.  Suspended data (data that has not failed)

2.  Failed data

I require to calcaulte how many ways the data can fail for example:

1. F1   Time = 10

2. S1  Time = 100

3. F2  Time = 200

4. S2  Time = 250

The number of combinations for this data is 3:

F1, S1, F2, S2

F1, F2, S1, S2

F1, F2, S2, S1

As the first element F1 is a failure nothing can replace this element.

 

I have been trying for a while in maple to programme this but have had very little luck.  Can anyone help me with this problem?

Thanks in Advance
