“Problem representation†and “ontology†are introduced as concepts critical to understanding foreign policy decision making. The article explicates these concepts and their relationship and focuses on such issues of representation rather than veridical descriptions of...

In constrast to "ordinary" sensitivity analysis in linear programming, the tolerance approach considers simultaneous and independent changes in the objective function coefficients and in the right-hand side terms. This approach yields a maximum tolerance percentage such that, as long as selected...

The tolerance approach to sensitivity analysis allows for simultaneous and independent variations of the elements of a column or a row of the coefficient matrix in a standard linear programming problem. In particular, the approach yields a maximum tolerance percentage within which the elements...
