Issues and Needs for Standard Classifications for Facility Management in Smart Manufacturing

As construction projects become larger and more complicated, the importance of information sharing among various project participants throughout the entire life-cycle of a facility is ever-increasing. Establishment of standard classification system is the most fundamental task for systematic and efficient management of construction information. In recent years, technology advancement of smart manufacturing, which is for intelligent factories supported by ICT combined with existing manufacturing technology, is becoming a key issue. However, due to the lack of information exchange (IE) standards for the management of smart manufacturing’s construction and operation, it is very limited for various construction participants to generate and share information by using the standards. In addition, each standard classification should be used in a combined manner in order to improve information processing efficiency. Standard classification requires a variety of facets such as facility, space, element, and work section. The purpose of this study is to propose a physical breakdown structure (PBS) that best reflects distinct characteristics of smart manufacturing. Firstly, the influencing factors for defining PBS were identified. A methodology for creating the facility classification suitable for smart manufacturing was then developed. Finally, cost breakdown structure (CBS) and work breakdown structure (WBS) were develop ed by combining the PBS and other standard classifications. This case-study of CBS and WBS formulation were used as a validation for the proposed methodology. The concept of "flexible WBS" by Jung and Woo [6] were utilized in this case study as well, in or der to accommodate the managerial requirements of an owner organization from the display industry.
