A family of heuristics based on linear programming (LP) relaxation (Wilhelm et al, 1994) resolve the strategic model, prescribing an area-wide contingency plan. Computational tests indicate that four ...

Benchmark instances modelling the supply chain of a fictive company producing and selling cell phones and accessories of different types. The instances formulate typical mixed-integer linear ...

Write down the Linear Program (LP) relaxation of an IP Plot the graphical representation of an IP and find the optimal solution Understand the relationship between optimal solution of an IP and the ...

ABSTRACT: In this paper a new approach for obtaining an approximation global optimum solution of zero-one nonlinear programming (0-1 NP) problem which we call it Parametric Linearization Approach (P.L ...

Abstract: This paper is about the primal-dual relationship in a mixed integer programming problem (MIP) in which integer variables are binary. It shows how the primal-dual relationship of a linear ...

Abstract: Phasor Measurement Units (PMUs) are essential devices in the monitoring and protection of modern power systems. However, its prohibitive cost may limit the wide installation of this device ...

Decision making problems in hierarchical managerial or public organizations are often formulated as two-level mathematical programming problems [1,2]. In the context of two-level programming, the ...
