Energy analysis (EA) within a building information modelling (BIM) enables consistent data integration in central repositories and eases information exchange, reducing rework. However, data loss during information exchange from different BIM uses or disciplines is frequent. Therefore, a holistic approach for different BIM uses enables a coherent life cycle information flow. The life cycle information flow drives the reduction of data loss and model rework and enhances the seamless reuse of information. The latter requires a specification of the EA key performance indicators (KPIs) and integrating those in the process.

The paper presents a set of KPIs extracted from the developed EA process maps and interviews with expert stakeholders. These KPIs stem from the literature review and link to the benefits of EA through industry expert review. The study includes (1) development and validation of EA process maps adjusted to requirements from different stakeholders. (2) KPIs aligned with the EA process map, (3) identification of the drivers that can facilitate life cycle information exchange and (4) opportunities and obstacles for EA within BIM-enabled projects.

This paper depicts a viable alternative for EA process maps and KPIs in a BIM-enabled AEC design industry. The findings of this paper showcase the need for an EA within BIM with these KPIs integrated for a more effective process conforming to the current Open BIM Alliance guidance and contributing towards sustainable life cycle information flow.

The limitation of the research is the challenge of generalising the developed EA process maps; however, it can be adjusted to fit defined organisational use. The findings deduced from the developed EA process map only show KPIs to have the ability to facilitate adequate information flow during EA.

The AEC industry will benefit from the findings of this primary research as the industry will be able to contrast its process maps and KPIs to those developed in the paper.

This paper benefits the societal values in EA for the built environment in the design stages. The subsequent life cycle information flow will help achieve a consistent information set and decarbonised built environment.

The paper offers a practical overview of process maps and KPIs to embed EA into BIM, reducing the information loss and rework needed in the practice of this integration. The applicability of the solution is contrasted by consultation with experts and literature.

During recent years integration has been the key issue for many manufacturing organisations. The authors review recent developments and ongoing research work and propose a methodology based on existing tools and techniques which would allow integration of the material flow system with the supporting information system.

The purpose of this paper is to evaluate the benefits of using the business network channel (Bunch) approach for modelling business networks and studying the business network evolution. Business network models put the structures of process models into context by visualising roles and communication channels for social interactions.

The research applies a case study-based approach involving the creation of business network visualisations to capture snapshots of an industrial firm's business network over a three-year period. A questionnaire-based study was also conducted with 18 key informants to evaluate the Bunch approach against existing business network modelling techniques.

This study shows that when business networks – as opposed to business processes – are diagrammatically modelled, patterns of relations between individuals can also be visualised and factored into how information systems are (re)designed and deployed. The study also finds that as business networks evolve, the ability to offer complementary channels of communication and coordinate business/technological information is vital to how upturns in process times improves overall business effectiveness and efficiency.

The major contribution of this paper is an exposition on how the Bunch approach could serve as a pedagogical tool for gaining clarity on their roles and links within the business and as an analytical tool for studying the evolution of business networks in relation to roles, links, information technologies, business strategies and business network anomalies.

The purpose of this study is to investigate ways of transferring knowledge and information during the life-cycle phases of construction projects, particularly between the construction and occupancy phases, and to find an approach to minimise knowledge and information gaps during the handover process.

The study applied a qualitative approach involving a literature review and an archival analysis of information flow in the studied cases of a construction project, followed by a cross-cases analysis and expert interviews. Data on information flow were collected from three cases of building construction projects in Perth, Western Australia. In addition, a total of 18 local facilities management experts were interviewed to identify the key reasons of knowledge and information gaps and to propose an effective knowledge flow model.

The findings of this study indicated a significant knowledge and information gap, which exists during the handover process in construction projects in Western Australia. The findings of case analysis and expert interviews identified that the project handover guidelines were often ignored in construction projects in Western Australia, and the handover phase was not given the same priority as the design and construction phases by most of the project stakeholders, which led to information and knowledge gaps between the project construction and post-occupancy phases. The study conducted, integrated knowledge and information flow modelling to analyse the knowledge and information gaps followed by mapping the gaps against existing knowledge sharing frameworks (KSFs) before proposing an integrated knowledge sharing conceptual model to improve current practice and to enhance the information flow during the various phases of the construction project life cycle.

The study is based on three cases in Perth, Western Australia, and thus the findings and recommendations are contextual. Whilst laying a good foundation to do so, further research is needed to investigate more cases in Western Australia and beyond to fully generalise the findings from this study.

The study contributes to improve the handover process and information flows in project life-cycle phases in Western Australia and develop an information flow model followed by bringing together existing KSFs, namely, the open communication channel (OCC), soft landing framework (SLF) and building information modelling (BIM), to propose an integrated knowledge sharing conceptual model. The methodology used here to analyse the information flow in a diagrammatic manner, the mapping of FM issues against the KSFs’ capabilities and a conceptual model to facilitate change in the industry’s silo mindset are the main contributions of this paper.

The purpose of this paper is to present research into the area of internet support for professional‐public communication through a deeper understanding of the role that a web site can provide in meeting the information needs of critically ill patients in intensive care units (ICUs). The communication between clinicians and members of the patient's family in the stressful ICU is modelled to give an integrated view of the situation and thereby allow for the incorporation of the views of all stakeholders on how the internet can meet this communication need.

The paper takes a broad, holistic, systemic approach that integrates the latest information and communications technology tools and processes with rich qualitative data from all stakeholder groups. The data are interpreted through the use of system dynamic modelling to visually conceptualise information flows and communication between clinicians and family members of patients.

The paper conceptualises, visualises and simulates the communication that takes place in complex stressful settings, such as, in ICUs thereby increasing the understanding of web‐support for professional‐public communication in the complex area of healthcare.

The broad approach of the paper has sacrificed, detailed and in depth analysis of all aspects of this issue which would require a much more extensive study.

The results have been of practical value to those developing a particular ICU web site and thus could inform others.

In addition to the findings, this paper is innovative in the way systems dynamics is used to model information flows. The results demonstrate the value of this technique for visualising and manipulating entire systems of this kind.

The purpose of this paper is to provide a better understanding of construction procurement within the supply chain management framework and develop a model for information flow. This paper adheres to the supply chain perspective and integration as theoretical point of departure, typically the role that information plays in a complex network such as construction procurement. The co‐ordination within partners and the integration across partners are critical in effective project management. Sharing information is a key component for tight integration to optimize the chain‐wide performance. It helps produce highest quality, low cost and minimum time to service. The tender offer from the procurer or invitation from a supplier triggers the requirement process. In response to the requirements there has to be an opposite flow of information, termed the fulfilment flow in the model described. The requirement information from a procurer is broken down to the project requirements for various partners in the project. Once the supply chain is identified in the postcontracting phase, information regarding specific tasks, materials, and so on, are communicated to the project partners. Information must be managed to bring in value. The quality of information received, the timeliness of the manner it is received and the costeffectiveness in obtaining the information determine the efficiency of a project partner. Another classification considered is that of the changing role of the partner with regard to information handling, i.e., the project partner as a recipient, decision‐maker and communicator of information. All these factors jointly contribute to increasing efficiency in construction procurement. This framework needs to be explored in future research to define subsequent steps in construction supply chain management, as the challenge is to adapt a totally integrated supply chain.

The purpose of this paper is to evaluate the appropriateness of gatekeeping theory, particularly its recent elaboration in journalism and communication studies for the investigation of information flows in academic libraries.

This paper uses the methods of conceptual analysis and thought experiment.

This paper finds that current elaborations of gatekeeping theory are useful for modeling library information flows, particularly identifying and evaluating influences on those flows. It is able to reframe intransigent issues around library neutrality and open access so that more nuanced approaches can be constructed.

Gatekeeping theory as elaborated by Shoemaker and Vos for journalism and communication studies, while occasionally referenced the library and information science (LIS) literature, has not been previously evaluated as a framework for library information flows. This is the first paper to assess the potential of aspects of the theory such as levels of analysis and multiplicity of channels to reframe issues in LIS.

About 70% of all aircraft accidents are caused by human–machine interaction, thus identifying and quantifying performance shaping factors is a significant challenge in the study of human reliability. An information flow field model of human–machine interaction is put forward to help better pinpoint the factors influencing performance and to make up for the lack of a model of information flow and feedback processes in the aircraft cockpit. To enhance the efficacy of the human–machine interaction, this paper aims to examine the important coupling factors in the system using the findings of the simulation.

The performance-shaping factors were retrieved from the model, which was created to thoroughly describe the information flow. The coupling degree between the performance shaping factors was calculated, and simulation and sensitivity analysis are based on system dynamics.

The results show that the efficacy of human–computer interaction is significantly influenced by individual important factors and coupling factors. To decrease the frequency of accidents after seven hours, attention should be paid to these factors.

The novelty of this work lies in proposing a theoretical model of cockpit information flow and using system dynamics to analyse the effect of the factors in the human–machine loop on human–machine efficacy.

Any computing architecture cannot be designed with complete confidentiality. As a result, at any point, it may leak the information. So, it is important to decide leakage threshold in any computing architecture. To prevent leakage more than the predefined threshold, quantitative analysis is helpful. This paper aims to provide a method to quantify information leakage in service-oriented architecture (SOA)-based Web services.

To visualize the dynamic binding of SOA components, first, the orchestration of components is modeled. The modeling helps to information-theoretically quantify information leakage in SOA-based Web services. Then, the paper considers the non-interference policy in a global way to quantify information leakage. It considers not only variables which interfere with security sensitive content but also other architectural parameters to quantify leakage in Web services. To illustrate the attacker’s ability, a strong threat model has been proposed in the paper.

The paper finds that information leakage can be quantified in SOA-based Web services by considering parameters that interfere with security sensitive content and information theory. A hypothetical case study scenario of flight ticket booking Web services has been considered in the present paper in which leakage of 18.89 per cent information is calculated.

The paper shows that it is practically possible to quantify information leakage in SOA-based Web services. While modeling the SOA-based Web services, it will be of help to architects to identify parameters which may cause the leakage of secret contents.

Despite much research on supply chain (SC) integration and the growing emphasis on recent information technology advancements as an enabler of improved performance, there has been limited research focussed specifically on information integration in supply chains (SCs). The purpose of this paper is to systematically review the literature on information integration in the fresh food supply chain (FFSC) from a holistic perspective.

Literature review is done by systematically collecting and analysing the recent literature to identify various participant entities of the FFSC information network and their specific information needs.

The information needs of FFSC entities are diverse but the needs are common across multiple entities.

This study only reviewed the FFSC-related literature; an extended study of the food industry may reveal a more comprehensive view.

These findings are useful for practitioners in understanding the participant entities in the information network and their information needs and for policymakers in formulating FFSC development initiatives.

The authors are not aware of another study that investigates the FFSC in a holistic approach, one that identifies the actors, their interactions and information needs.
