“…It has been used to identify information flows and iterations within a process and to schedule activities with the objective of optimizing the task order. After the identification of information flow, DSM rearranges the order of activities to reduce unnecessary feedbacks and reverse information flows, thereby reducing engineering rework in the planning phase [42,47]. Therefore, DSM can be used to identify and facilitate information flows in the integrated design process for modular construction and to alleviate the complexity of the flow.…”

In modular construction projects, unit production and onsite work are conducted concurrently, enabling shorter duration, lower cost, and improved quality. Because of the nature of the work, building design details should be determined early in the design phase, which requires information from participants. However, the design process for stick-built construction does not include such information, which leads to errors in design, such as omissions and conflicts of information from participants, causing reworking in the design phase. To reduce errors, an information flow should be identified representing when/what/how the information should be shared, and with whom. This paper proposes an integrated design process based on the information flow. To identify the flow, a precedence relationship between activities is represented using a dependency structure matrix (DSM). Then, the order of activities is rearranged using a partitioning algorithm. In this manner, unnecessary feedback and reverse information flow, which are related to errors, are reduced. Finally, the rearranged activities are proposed as an integrated design process. To validate the impact of the proposed process and methodology, interviews with experts were conducted. The validation results suggest that the project delivery method should also be considered in the early project phase in practical application.

“…Most studies related to modeling of information flows within the A/E/C industry have focused on activities at the design and engineering phases [19][20][21]. Among such studies, Sacks et al [22] collected detailed process models of the information that flows from engineering to erection phases within precast companies.…”

“…Some concerns in scheduling the design process Steward (1981) first developed Design Structure Matrix (DSM) to represent task dependencies in product design. DSM has been found to be very effective in identifying and managing information flows between activities, and ordering tasks for greater concurrency and reducing cyclical loops (Oloufa et al 2004;Pektaş and Pultar 2006;and Collins et al 2009). The DSM is a square matrix with equal rows and columns corresponding to the number of design tasks.…”
