Concave objective functions which are both piecewise linear and separable are often encountered in a wide variety of management science problems. Provided the constraints are linear, problems of this ...

We formulate a risk-averse two-stage stochastic linear programming problem in which unresolved uncertainty remains after the second stage. The objective function is formulated as a composition of ...

Classification of diet models We distinguish between two classes: 1 Single-objective problems: minimize (or maximize) one linear function of Xi: Minimize.
