mrt: Relation between variables Maintenance done (M = true) and Repairs at sea (R)This dataset is the tt matrix establishing a set of two relations between the two variables. First, Repairs = true if Maintenance = true in (M x R). We are 10% sure that there will be Repairs if maintenance is done. Second, Repairs = false if Maintenance = true in (M x R). We are 70% sure that there will be no repairs if maintenance is done.
mrtA (0,1) matrix with 4 rows and 6 columns.
value = 0, not used
Identification numbers of the two variables. Column 3,4: variable 6; columns 5,6: variable 8
identification number of the specification
the value of the specification, a number between 0 and 1
1 if true is part of the specification, 0 otherwise
1 if false is part of the specification, 0 otherwise

These two relations are implication rules. The remaining mass of 0.2 is allotted to the frame. To construct the tt matrix, we put the variables M and R side by side, as in a truth table representation. Each pair of the subset is described by a row of the matrix as a vector of zeros and ones.
