Knowledge-Based Optimization of Building Maintenance, Repair, and Renovation Activities to Improve Facility Life Cycle Investments

Forecasting Repair Schedule for Building Components Based on Case-Based Reasoning and Fuzzy-AHP

“…Proper maintenance of buildings facilitates the optimal performance of buildings to residents throughout their life cycle because it is closely related to the safety of residents [17]. However, general difficulties are experienced in planning building maintenance because buildings consist of several components [1] and building components operate interdependently [5]. Moreover, the complexity of buildings is increasing and maintenance costs account for a large portion of life cycle cost [18].…”

“…Therefore, the accuracy of their proposed model is unclear if the weights of the attributes are not described because the results of CBR depend on the weight of attributes. Grussing and Liu [5] developed a model for selecting optimal MR&R (maintenance, repair, and renovation) activities for multiple years to minimize life cycle costs while maximizing the performance of facilities. They predicted the performance state of building components through the condition index and the capability index and estimated MR&R costs of building components utilizing the condition index (CI).…”

“…However, they did not consider factors directly related to building maintenance or assess relevant impact factors before implementing CBR. Grussing and Liu [5] developed a model that selects optimal MR&R activities and Ghodoossi et al [23] proposed a framework that predicts a cost-effective intervention schedule. However, their actual applicability and accuracy could not be ensured because the model and framework were not validated with objects of varying criteria.…”

“…To ensure that buildings are in good condition for daily life and working, a specific maintenance plan ensuring the sustainability of the building is needed. Moreover, a systematic maintenance plan is required because the aging process affects repair costs for maintaining the function [4] and safety of buildings [5], especially in residential buildings. Aged buildings around the world account for a high proportion of all buildings.…”

Module-based Renewal Planning of Energy Using Products for Reducing Environmental Load and Life Cycle Cost

“…We have been accumulating such artifacts in our society to the extent that maintenance and renewal of existing artifacts require more financial resources than creating new ones. As such, we urgently need to improve the effectiveness and efficiency of their maintenance and renewal [1].…”
