Thus, the objective of this study is to conduct an in-depth investigation of these matrix-based design concepts to understand their applicability for better control on changes in construction projects. In spite of potential benefits of matrix-based approaches, previous studies have not dealt with combining AD and DSM for project change management research. DSM provides a methodology for analyzing changes through modeling interactions among the parameters.
AD guides the designers to examine changes by modeling requirements and parameters relationships in a structured manner from early design stages. Axiomatic Design (AD) and Design Structure Matrix (DSM) are two popular matrix-based modeling concepts that can model changes from a parameter perspective. Changes can be better understood through modeling parameters relationships.
They are not only related to design but also depict and guide design processes. Parameters play an essential role in change communication. The primary cause of these changes includes inadequate requirements briefing, interdependencies, iterative loops, inadequate knowledge of construction methods, and the delayed inputs of information from interface teams. The findings revealed framework can identify and predict all possible changes accurately.Ĭhanges are inevitable in construction projects. Framework is validated using data from an ongoing hospital construction project. The scope of study is to predict delays due to requirement changes. A schedule risk model is proposed for estimating delays due to changes in entity types. MDM principles are used for tracking change propagations across multiple entity types. AD principles are utilized for early change identification. The proposed matrix-based framework integrates two matrix-based modeling concepts: Axiomatic Design (AD) and Multiple Domain Matrix (MDM). Therefore, objective of the study is to develop a matrix-based framework to predict changes by modeling multiple entity types in a construction project. To predict changes and their impacts holistically, entity types should be modeled in an integrated manner explicitly. However, different set of entity types in a construction project such as teams, components, deliverables, activities and parameters, as well as complex interdependencies that exist among these entity types, makes difficult to manage changes.
A key challenge of change management is to identify changes and predict their impacts before implementation so that impacts can be minimized. Changes are inevitable in a construction project and can impact project's time, cost, other aspects such as labor productivity, safety, and working relationships.
