A multistate-based control system approach toward optimal maintenance planning

Abstract

This paper incorporates the multi-state system into a control system approach to address the maintenance plan optimization problem. The maintenance plan focuses on the totality of a set of items. A building energy efficiency retrofitting context is employed, where the retrofitted items are categorized into several homogeneous groups. The homogeneous group population dynamics and the aggregate performance dynamics under the impacts of multistate deteriorations and maintenances are for-mulated as a control system model. Thereafter, the maintenance planning optimization is cast into an optimal control problem. An MPC based approach is employed to solve the optimal control problem with system uncertainties. A case study is conducted to illustrate the effectiveness of the present approach.
