This research standardizes a knowledge structure for estimation in the construction field by creating a method to enhance cost management efficiency of construction projects while meeting the need for reusability of accumulated construction information. The construction knowledge structure was developed to execute the project cost estimation with an ontological concept. The knowledge framework was defined and relevant examples were addressed to explain the structure. The detailed estimation process and methodology for using standard unit price information was also developed to strengthen cost information interoperability by utilizing standard classification systems, such as MasterFormat, UniFormat, UniClass, and ISO 12006. This concept may be proposed as a method of connecting construction information based on a standard cost classification system in order to improve estimation efficiency by increasing the connectivity of cost information. Ontology can be a powerful tool when used in conjunction with interoperability to manage the massive volume of construction information for cost management. This methodology can expand to integrated management in cost and time to derive additional classes for work breakdown structure (WBS). Thus, ontology may improve the efficiency of cost estimation and systematization by reusing construction information. As a further step, the interoperability method will enhance overall construction project management.

EPC项目本体成本估算知识框架的开发

本研究通过创建一种方法来提高建筑项目的成本管理效率,同时满足积累的建筑信息可重用性的需求,从而标准化了建筑领域中用于估算的知识结构。开发了构造知识结构,以本体论的概念执行项目成本估算。定义了知识框架,并提供了相关示例以解释该结构。还开发了使用标准单价信息的详细估算过程和方法,以通过利用标准分类系统(例如MasterFormat,UniFormat,UniClass和ISO 12006)来增强成本信息的互操作性。可以提出该概念作为基于标准成本分类系统的连接施工信息的方法,以便通过增加成本信息的连通性来提高估计效率。当与互操作性结合使用来管理大量建筑信息以进行成本管理时,本体可以是一种强大的工具。这种方法可以扩展到成本和时间上的集成管理,以得出工作分解结构(WBS)的其他类别。因此,本体可以通过重用施工信息来提高成本估算和系统化的效率。作为进一步的步骤,互操作性方法将增强总体建设项目管理。当与互操作性结合使用来管理大量建筑信息以进行成本管理时,本体可以是一种强大的工具。这种方法可以扩展到成本和时间上的集成管理,以得出工作分解结构(WBS)的其他类别。因此,本体可以通过重用施工信息来提高成本估算和系统化的效率。作为进一步的步骤,互操作性方法将增强总体建设项目管理。当与互操作性结合使用来管理大量建筑信息以进行成本管理时,本体可以是一种强大的工具。这种方法可以扩展到成本和时间上的集成管理,以得出工作分解结构(WBS)的其他类别。因此,本体可以通过重用施工信息来提高成本估算和系统化的效率。作为进一步的步骤,互操作性方法将增强总体建设项目管理。本体可以通过重用施工信息来提高成本估算和系统化的效率。作为进一步的步骤,互操作性方法将增强总体建设项目管理。本体可以通过重用施工信息来提高成本估算和系统化的效率。作为进一步的步骤,互操作性方法将增强总体建设项目管理。
