TWO OPERATIONS RESEARCH MODELS FOR DETERMINATION OF CONTROL DEVICE LOCATION AND SIZES IN VENTILATION NETWORKS

摘要

This paper presents application of Operations Research for optimization of ventilation control device locations and sizes in the controlled and semi-controlled flow mine ventilation networks. For the controlled ventilation network, an algorithm of mixed integer programming is introduced. For the semi-controlled network, a nonlinear, non-convex model is implemented. Numerical examples are used to demonstrate the applicability of these models.
