A Heuristic Approach for the Optimization of Maintenance Task Plans in Electric Power Distribution Systems With Resource Constraints

In this study, we present a new approach for the optimized scheduling of maintenance tasks in electric power distribution networks based on a classic optimization technique. The original mixed-integer non-linear programming model is linearized using the piecewise linearization technique, adopting a classical pseudo-dyn...

Mathematical Optimization in Startups: An Analytical Study of the Assignment Problem

Most start-ups work in a fast-paced, resource-constrained environment where efficient resource allocation can be a critical factor for success. The assignment problem (a specific type of LPP) is a well-established optimization model in operations research. It presents valuable solutions for start-ups aiming to streamli...
