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.
