Decisional variables

Linear programming involves only continuous variables x R " mixed-integer linear programming also involves discrete (integer or Boolean) variables y e N , called decisional variables. 

Mixed-integer linear programming has a significant impact. In spite of certain ad hoc algorithms designed to reduce the permutations of branches of decisional variables (i.e., branch bound methods, see for example, Martin, 1999), MILP problems can be solved as a series of hnear programming, one for each... 

The meaning of the application of fuzzy models in risk analysis is to provide mathematical formulations that could characterize the uncertain parameters involved in complex safety evaluation me ods. Fuzzy logic is a decisional system based on linguistic rules once the membership functions have been defined for all the fuzzy variable sets, each set has to be connect by...
