Selection Model of Building Demolition Method Based on Expert System

Abstract

Demolition needs special attention because the planning process is complex and has a high risk. In decision making, practitioners face various conditions that influence the choice of demolition methods. This study aims to develop an optimal model for building demolition methods based on the building characteristics. Identification of criteria was conducted in in-depth literature review and interviews with practitioners who have carried out demolition in Indonesia. The five criteria used in this study were structural characteristics, field conditions, costs, previous experience and time. Furthermore, Multiclass and Multi-label Classification were used to make the optimum demolition method decisions. For model validation, 27 story buildings in Indonesia were used as case studies. The simulation results show that the proposed model can make decisions on the selection of demolition methods with an accuracy of 89.3%. In addition to being able to provide an optimum decision on demolition methods, this model can also provide an estimate of the possible impacts of the selected demolition method.

Environmental Assessment of Demolition Tools Used in Townhouse Demolition: System Dynamics Modeling

“…Anumba et al [12] used an integrated system for demolition technique selection and concluded that the prototype system developed provides users with a clear and structured framework that could improve the decision-making process. Oryza et al [13] utilized the selecting model of building demolition method based on an expert system and concluded that the model can make decisions on the selection of demolition methods with an accuracy of judgment. However, unstructured intuition by demolition engineers based on skill, experience, judgment, or knowledge may sometimes lead to error and inconsistencies, and the AHP utilized in selecting demolition tools are linear dependencies between items of different decision-making levels and not suitable for complex problems which are characterized by dependencies, interactions, and feedback and especially by the dynamic nature of the decision taken.…”
