The format of numerical value of
reliability for each module is:

value1, value2,
value3, ..... valueN

where, value1 is the numerical
reliability of module A, value2 is the numerical reliability of module
B, and so on.

For example, there are 4 modules
in the system, R_{a} = 0.85, R_{b} = 0.78, R_{c}
= 0.83, R_{d} = 0.94,

then you should input :

If it reports that the numerical value is invalid, please check that whether what you input are correct.0.85, 0.78, 0.83, 0.94

1. all data should be numericalreturn

2. all input data should be nonnegative

3. all input data should be less than or equal to 1.0
