“…It can be used to represent architecture in terms of the relationships between its constituent components (Browning, 2001). The sequence of activities is vital in design projects, in particular interdisciplinary projects, and such sequencing is influenced by the information dependency among the activities (Maheswari and Varghese, 2005). Zhao, Lv and You (2008) applied DSM and Monte Carlo Simulation to predict change in construction project.…”

“…However, it is more demanding in energy efficient retrofit projects where varying number of simulations and analyses are carried out requiring multiple exchange of information between heterogeneous applications. During this process, several activities are carried out for the design of each building element/system and sequencing these activities is influenced by the information dependency (Maheswari and Varghese, 2005). The activities often interact internally and externally with other building elements/systems design activities.…”

Access and exchange of building information in a timely and standard manner between construction project teams and applications during design and construction, plays a major role in assuring efficient building energy simulation during retrofitting. Yet, in spite of several efforts in major technological developments in information management, building data and information remains highly fragmented and frequently inaccessible to project teams. This paper presents a table for categorization of information exchanges items and illustrates their dependencies between internal process activities, and between activities of different processes. The paper uses the HVAC design process as a baseline to map-out the information input-and-output relationships of various activities and shows how an information item produced by an activity is consumed by another, thus creating information exchanges dependency. The table can serve as a reference point for project teams and for software developers to understand interoperability requirements of process activities and applications. It will also be beneficial to analyze impact of changes as change to an information exchanges item can impact on other activities where it is required as an input. The paper concludes by formulating a roadmap to utilize the table in order to support development of Information Delivery Manual (IDM) and other information exchanges initiatives. INTRODUCTIONIt is generally believed that exchange of relevant information is extensive and one of the main challenges in design, construction and operations of buildings (Hjelseth, 2010). This is the case for both new and retrofit projects. However, it is more demanding in energy efficient retrofit projects where varying number of simulations and analyses are carried out requiring multiple exchange of information between heterogeneous applications. During this process, several activities are carried out for the design of each building element/system and sequencing these activities is influenced by the information dependency (Maheswari and Varghese, 2005). The activities often interact internally and externally with other building elements/systems design activities. Inadequate exchange of information could potentially impact the analyses adversely.The need to integrate processes and applications seamlessly for building energy simulations during design is colossal. The various domain specific analyses, e.g., HVAC, structural and lighting can very effectively make accurate analysis and energy efficiency related decisions based on effective exchange of information. A major challenge in seamless exchange of information is the information incompatibility problem as different models and formats are used by different actors, thus perpetuating the fragmentation of information flow (Kriphal and Grilo, 2012). Seamless exchange of information of different formats between the specific domains, and how to specify the exchange requirements for the various simulation activities remain challenging. This (i.e., seamless

“…Entities in any design phase need not follow the typical “finish to start” (FS) relationship only. Usually, several instances of information exchanges exist between any two design entities as preliminary and final (Maheswari and Varghese, 2005; Terwiesch et al , 1998, 2002). Preliminary information can pop-up either through interdependent entity execution or through forced overlapping of the semi-independent or dependent entities.…”

Purpose The design phase is generally characterized with two-way multiple information exchanges/overlaps between the interdependent entities. In this paper, entity is a generic term to represent teams, components, activities or parameters. Existing approaches can either capture a single overlap or lack practical application in representing multiple overlaps. The beeline diagraming method (BDM) network is efficient in representing multiple overlaps for construction projects. However, it considers any entity as indivisible and cannot distinguish partial criticality of entities. In reality, the design phase in any construction project is driven by need basis and often has numerous interruptions. Hence, there is a need to develop an alternate network analysis for BDM for interruptible execution. The paper aims to discuss these issues. Design/methodology/approach A pilot study is conducted to formulate the hypothetical examples. Subsequently, these hypothetical BDM examples are analyzed to trace a pattern for criticality. This pattern study along with the existing precedence diagramming method network analysis enabled to derive new equations for forward pass, backward pass and float. Finally, the proposed concepts are applied to two design cases and reviewed with the design experts. Findings The proposed network analysis for BDM is efficient for interruptible entity execution. Practical implications The proposed BDM network is an information-intensive network that enables the design participants to view the project holistically. Application to two distinct cases emphasizes that the concept is generic and can be applied to any project that is characterized with beelines. Originality/value An alternate network analysis for BDM is investigated for interruptible entity execution. This study also clarifies the related concepts – interdependency, iteration, overlaps and multiple information exchanges/linkages.

“…The rows and columns of DSM correspond to the tasks, and the matrix reveals the inputs and outputs of tasks, by manipulating the matrix, the feedback marks can be eliminated or reduced, this process is called partitioning [12,13]. According to the input/output, the subsets of DSM elements that are mutually exclusive or minimally interacting should be determined, this process is called clustering [14][15][16].…”

Multi-product collaborative development is adopted widely in manufacturing enterprise, while the present multi-project planning models don't take technical/data interactions of multiple products into account. To decrease the influence of technical/data interactions on project progresses, the information flow scheduling models based on the extended DSM is presented. Firstly, information dependencies are divided into four types: series, parallel, coupling and similar. Secondly, different types of dependencies are expressed as DSM units, and the extended DSM model is brought forward, described as a block matrix. Furthermore, the information flow scheduling methods is proposed, which involves four types of operations, where partitioning and clustering algorithm are modified from DSM for ensuring progress of high-priority project, merging and converting is the specific computation of the extended DSM. Finally, the information flow scheduling of two machine tools development is analyzed with example, and different project priorities correspond to different task sequences and total coordination cost. The proposed methodology provides a detailed instruction for information flow scheduling in multi-product development, with specially concerning technical/data interactions.
