以建筑节能改造为背景，探讨了以节能为目标的维修计划优化问题。提出了一个子问题，即建筑改造设施的纠正性维修计划（BRFCMP）问题，其中涉及故障的改造项目的纠正性维修。优化问题的主要考虑因素是同质改装项目组的总体性能，而不是单个项目的性能。提出了一种总体水平优化模型来解决BRFCMP问题。当进一步考虑到的不确定性，优化问题被铸造成一个最优控制问题，以减少随之而来的不利影响，给定的动态性质的总性能的项目组在操作过程中。优化和控制系统的方法来解决BRFCMP问题没有或考虑不确定性。以一个实际的建筑节能改造项目为例，探讨了维护对建筑节能的重要作用。仿真结果验证了所提方法的有效性。
This paper discusses the maintenance plan optimization problem for the energy efficiency purpose in the building energy efficiency retrofitting context. A subproblem namely the Building Retrofitted Facilities Corrective Maintenance Planning (BRFCMP) problem is proposed, where the corrective maintenance for malfunctioning retrofitted items are involved. The aggregate performances of the homogeneous retrofitted item groups, instead of the individual item performances, are the main consideration of the optimization issue. An aggregate population level optimization model is proposed to address the BRFCMP problem. When further taking into account the uncertainties, the optimization problem is cast into an optimal control problem to reduce the consequent adverse impact, given the dynamic nature of the aggregate performances of the item groups during operation. Both the optimization and control system approaches are applied to solve the BRFCMP problem without or considering uncertainties. An actual building retrofitting project is used as the case study to investigate the important role of maintenance to the building energy efficiency. The effectiveness of the proposed approaches is verified by simulation results.
