SCHLUNZ, E.B. e VAN VUUREN, J.H.. The application of a computerised decision support system for generator maintenance scheduling: a South African case study. S. Afr. J. Ind. Eng. [online]. 2012, vol.23, n.3, pp.169-179. ISSN 2224-7890.
In the generator maintenance scheduling (GMS) problem, a schedule is sought for the planned maintenance outages of generating units in a power system. The GMS model considered in this paper is formulated as a mixed-integer quadratic program assuming a reliability objective, subject to certain constraints. A generic GMS solution methodology is derived, capable of solving general GMS problem instances that conform to this model structure, and implemented in a computerised decision support system. The decision support system is then used to solve a real-life case study in the South African national power system.
