An integrated product and process information modelling system for on-site construction

The inadequate infrastructure that exists for seamless project team communications has its roots in the problems arising from fragmentation, and the lack of effective co-ordination between stages of the construction process. The use of disparate computer-aided engineering (CAE) systems by most disciplines is one of the enduring legacies of this problem and makes information exchange between construction team members difficult and, in some cases, impossible. The importance of integrating modelling techniques with a view to creating an integrated product and process model that is applicable to all stages of a construction project's life cycle, is being recognised by the Construction Industry. However, improved methods are still needed to assist the developer in the definition of information model structures, and current modelling methods and standards are only able to provide limited assistance at various stages of the information modelling process. This research investigates the role of system integration by reviewing product and process information models, current modelling practices and modelling standards in the construction industry, and draws conclusions with similar practices from other industries, both in terms of product and process representation, and model content. It further reviews various application development tools and information system requirements to support a suitable integrated information structure, for developing an integrated product and process model for design and construction, based on concurrent engineering principles. The functional and information perspectives of the integrated model, which were represented using IDEFO and the unified modelling language (UML), provided the basis for developing a prototype hyper-integrated product and process information modelling system (HIPPY). Details of the integrated conceptual model's implementation, practical application of the prototype system, using house-building as an example, and evaluation by industry practitioners are also presented. It is concluded that the effective integration of product and process information models is a key component of the implementation of concurrent engineering in construction, and is a vital step towards providing richer information representation, better efficiency, and the flexibility to support life cycle information management during the construction stage of small to medium sized-building projects

Influence of big-data based digital media on spiritual goal strivings and well-being: a media richness theory perspective

A thesis submitted to the University of Bedfordshire in partial fulfilment of the requirements for the degree of Doctor of PhilosophyBig-Data characteristics and spirituality are seldom discussed together in the context of assistances provided by big-data based digital media on spiritual goal strivings (SGS). This study’s main aim is to investigate the significance of this relationship between big-data based digital media characteristics and SGS outcomes, and its impact on well-being. A theoretical integrated framework was developed underpinned by Media Richness Theory (MRT) to capture the influence of big-data based digital media characteristics on SGS outcomes. The research design of this epistemological study adopted positivism type of scientific enquiry; employing a deductive approach confining under quantitative research methods and used survey data collection technique. Non-probability self-selection sampling was used and a total of 987 valid responses were analysed by applying statistical tests and techniques following rigorous statistical Structural Equation Modelling (SEM) techniques using IBM AMOS. The results revealed the existence of significant relationship between the big-data based digital media characteristics and SGS outcomes. The study also reveals that digital media characteristics influences successes in SGS outcomes where certain aspects of digital media characteristics are shown to assist SGS towards accomplishments while some have shown to cause hindrances for SGS to be accomplished. The results also confirmed that success in SGS accomplishments increased vitality aspect of well-being. This information is vital for decision making, implementing and planning for various spiritual stakeholders mainly spiritual seekers, spiritual organisations and user experience (UX) - user interface (UI) designers of big-data based digital media developers. With this knowledge contribution, the stakeholders are able to make informed decisions and look for efficient strategies that would provide effective, reliable and sustainable assistances towards SGS accomplishments. The study provides theoretical contribution to the body of IS literature with an integrated and extended MRT conceptual framework providing the foundation for exploring the extended MRT instrument for future studies in similar thematic contexts by other researchers. Further, this study’s empirically validated evidence provides practical contribution in its effort to spiritual stakeholders with the confidence to adopt and develop effective strategies to implement big-data based digital systems in organisations with selective configuring and tuning to utilise the accelerating aspects of the medium for effective SGS accomplishments. UX and UI stakeholders will benefit significantly to be able to design and develop digital systems supporting SGS based on a deeper understanding of the certain factors from this study which indicates significant influence on SGS and to look for effective strategies in their development phase to accommodate the revealed concerns and assistances that would provide efficient, consistent and sustainable spiritual goal outcomes. Overall the findings in this study provide optimistic future for utilising the assistances provided by big-data based digital media capabilities for SGS accomplishments. Overall statistical results reveal that the advantages of assistances provided towards SGS outcomes outweighed the disadvantages of hindrances towards SGS outcomes

Organizational effectiveness : a study of the concept with empirical reference to a general nurse training system.

The concept of organizational effectiveness is of vital importance to accountants because it forms the ultimate criterion for the design of accounting information systems for control. It also has close conceptual links with the concept of corporate accountability. Depending on how an accountant defines effective organizational behaviour he/she will seek to design management information systems that implement and achieve this perspective. Depending on how and in whose interests a corporation is seen to be working towards accountants will design appropriate corporate reports. This thesis examines the concept in detail and argues that theories of effectiveness have" generally been developed on what Habermas calls a technical level of interest. Little research attention has been paid to developing concepts of effectiveness on the hermeneutical and critical levels of interest. Critique, however, is felt to be vital for the moral and intellectual development of social theory and social science, of which accounting is constitutive. Indeed, Habermas argues that the function of theoretical and practical discourse is to help lead to an ideal situation of rational consensus and of free speech which is unconstrained by sources of domination. Based on this epistemological stance, the thesis develops a technically-interested theory of O.E. This and the research inSights it produces are evaluated and an integrated, critical theory of O.E. is proposed. This is then used to generate additional information from the same empirical base~ a process which shows the inadequacy of developing only technical theories of effectiveness. Finally, the implications of such an integrated theory of O.E. for accounting are examined and new research directions are suggested. The structure of the thesis itself has attempted to be an analogue of critique~ beginning with a technical theory of O.E., evaluating this and proposing an enriched, integrated alternative. It has also attempted to be a thesis in the social science, emphasizing the holism of social knowledge

Communicating Conceptual Design of Mechatronic Systems

Today\u27s engineering designers must adapt to a changing model of product development. In the past, a single engineer could design, develop and deploy competitive systems --this is often no longer the case. Designing a mechanical system with integrated microprocessor control requires the collaboration of a cross-disciplinary team of engineers and, in many cases, no single member of the team understands the workings of the entire system. Consequently, as systems become increasingly complex, the ability to collaborate and reliably communicate design information becomes more and more crucial. Effective communication 1s particularly critical in conceptual design, where a poor decision has the highest potential cost. Efficiently exchanging conceptual design information requires a medium that can encapsulate complex, domain-specific concepts and yet be generically readable and concise. This thesis surveys recent work in the area of engineering design and the communication of conceptual design information. Research in these areas is contrasted with the current practices of Mechatronics Engineering, and potential gaps in the literature are identified. This work suggests that the integration of systems architecture and the mechatronic concept could provide an incremental step towards improving the design of mechatronic products. Chapter 1 presents a short introduction to the concepts of mechatronics and conceptual design. A brief history of the evolution of mechatronics is also presented. Chapter 2 reviews recent work in engineering processes, with a focus on how recent developments relate to mechatronics engmeermg. In this chapter, quality functional deployment, concurrent engineering, object-oriented methods and systems architecture are discussed. Chapter 3 focuses on specific processes and tools for the development of mechatronic systems, including integrated design and simulation, the mechatronic design process, and current issues in mechatronics engineering. Chapter 4 discusses current work in the area of conceptual design, with a focus on the communication of conceptual design information. Chapter 5 reviews the previous chapters to identify areas of mechatronics that are in the most need of additional research. Finally, in Chapter 6, conclusions are drawn and recommendations are made

Applications integration for manufacturing control systems with particular reference to software interoperability issues

The introduction and adoption of contemporary computer aided manufacturing control systems (MCS) can help rationalise and improve the productivity of manufacturing related activities. Such activities include product design, process planning and production management with CAD, CAPP and CAPM. However, they tend to be domain specific and would generally have been designed as stand-alone systems where there is a serious lack of consideration for integration requirements with other manufacturing activities outside the area of immediate concern. As a result, "islands of computerisation" exist which exhibit deficiencies and constraints that inhibit or complicate subsequent interoperation among typical MCS components. As a result of these interoperability constraints, contemporary forms of MCS typically yield sub-optimal benefits and do not promote synergy on an enterprise-wide basis. The move towards more integrated manufacturing systems, which requires advances in software interoperability, is becoming a strategic issue. Here the primary aim is to realise greater functional synergy between software components which span engineering, production and management activities and systems. Hence information of global interest needs to be shared across conventional functional boundaries between enterprise functions. The main thrust of this research study is to derive a new generation of MCS in which software components can "functionally interact" and share common information through accessing distributed data repositories in an efficient, highly flexible and standardised manner. It addresses problems of information fragmentation and the lack of formalism, as well as issues relating to flexibly structuring interactions between threads of functionality embedded within the various components. The emphasis is on the: • definition of generic information models which underpin the sharing of common data among production planning, product design, finite capacity scheduling and cell control systems. • development of an effective framework to manage functional interaction between MCS components, thereby coordinating their combined activities. • "soft" or flexible integration of the MCS activities over an integrating infrastructure in order to (i) help simplify typical integration problems found when using contemporary interconnection methods for applications integration; and (ii) enable their reconfiguration and incremental development. In order to facilitate adaptability in response to changing needs, these systems must also be engineered to enable reconfigurability over their life cycle. Thus within the scope of this research study a new methodology and software toolset have been developed to formally structure and support implementation, run-time and change processes. The tool set combines the use of IDEFO (for activity based or functional modelling), IDEFIX (for entity-attribute relationship modelling), and EXPRESS (for information modelling). This research includes a pragmatic but effective means of dealing with legacyl software, which often may be a vital source of readily available information which supports the operation of the manufacturing enterprise. The pragmatism and medium term relevance of the research study has promoted particular interest and collaboration from software manufacturers and industrial practitioners. Proof of concept studies have been carried out to implement and evaluate the developed mechanisms and software toolset

Reference Ontologies to Support the Development of New Product-Service Lifecycle Systems

In competitive and time sensitive market places, organisations are tasked with providing Product Lifecycle Management (PLM) approaches to achieve and maintain competitive advantage, react to change and understand the balance of possible options when making decisions on complex multi-faceted problems, Global Production Networks (GPN) in one such domain in which this applies. When designing and configuring GPN to develop, manufacture and deliver product-service provision, information requirements that affect decision making become more complex. The application of reference ontologies to a domain and its related information requirements can enhance and accelerate the development of new product-service lifecycle systems with a view towards the seamless interchange of information or interoperability between systems and domains. This paper present preliminary results for the capture and modelling of end-user information and an initial higher level reference core ontology for the development of reference ontologies to ameliorate product-service lifecycle management for GPNPalmer, C.; Urwin, E.; Pinazo-Sanchez, J.; Sánchez Cid, F.; Pajkovska-Goceva, S.; Young, R.

Towards integrated island management: lessons from Lau, Malaita, for the implementation of a national approach to resource management in Solomon Islands: final report

Solomon Islands has recently developed substantial policy aiming to support inshore fisheries management, conservation, climate change adaptation and ecosystem approaches to resource management. A large body of experience in community based approaches to management has developed but “upscaling” and particularly the implementation of nation-wide approaches has received little attention so far. With the emerging challenges posed by climate change and the need for ecosystem wide and integrated approaches attracting serious donor attention, a national debate on the most effective approaches to implementation is urgently needed. This report discusses potential implementation of “a cost-effective and integrated approach to resource management that is consistent with national policy and needs” based on a review of current policy and institutional structures and examination of a recent case study from Lau, Malaita using stakeholder, transaction and financial cost analyses

Requirements engineering for computer integrated environments in construction

A Computer Integrated Environment (CIE) is the type of innovative integrated information system that helps to reduce fragmentation and enables the stakeholders to collaborate together in business. Researchers have observed that the concept of CIE has been the subject of research for many years but the uptake of this technology has been very limited because of the development of the technology and its effective implementation. Although CIE is very much valued by both industrialists and academics, the answers to the question of how to develop and how to implement it are still not clear. The industrialists and researchers conveyed that networking, collaboration, information sharing and communication will become popular and critical issues in the future, which can be managed through CIE systems. In order for successful development of the technology, successful delivery, and effective implementation of user and industry-oriented CIE systems, requirements engineering seems a key parameter. Therefore, through experiences and lessons learnt in various case studies of CIE systems developments, this book explains the development of a requirements engineering framework specific to the CIE system. The requirements engineering process that has been developed in the research is targeted at computer integrated environments with a particular interest in the construction industry as the implementation field. The key features of the requirements engineering framework are the following: (1) ready-to-use, (2) simple, (3) domain specific, (4) adaptable and (5) systematic, (6) integrated with the legacy systems. The method has three key constructs: i) techniques for requirements development, which includes the requirement elicitation, requirements analysis/modelling and requirements validation, ii) requirements documentation and iii) facilitating the requirements management. It focuses on system development methodologies for the human driven ICT solutions that provide communication, collaboration, information sharing and exchange through computer integrated environments for professionals situated in discrete locations but working in a multidisciplinary and interdisciplinary environment. The overview for each chapter of the book is as follows; Chapter 1 provides an overview by setting the scene and presents the issues involved in requirements engineering and CIE (Computer Integrated Environments). Furthermore, it makes an introduction to the necessity for requirements engineering for CIE system development, experiences and lessons learnt cumulatively from CIE systems developments that the authors have been involved in, and the process of the development of an ideal requirements engineering framework for CIE systems development, based on the experiences and lessons learnt from the multi-case studies. Chapter 2 aims at building up contextual knowledge to acquire a deeper understanding of the topic area. This includes a detailed definition of the requirements engineering discipline and the importance and principles of requirements engineering and its process. In addition, state of the art techniques and approaches, including contextual design approach, the use case modelling, and the agile requirements engineering processes, are explained to provide contextual knowledge and understanding about requirements engineering to the readers. After building contextual knowledge and understanding about requirements engineering in chapter 2, chapter 3 attempts to identify a scope and contextual knowledge and understanding about computer integrated environments and Building Information Modelling (BIM). In doing so, previous experiences of the authors about systems developments for computer integrated environments are explained in detail as the CIE/BIM case studies. In the light of contextual knowledge gained about requirements engineering in chapter 2, in order to realize the critical necessity of requirements engineering to combine technology, process and people issues in the right balance, chapter 4 will critically evaluate the requirements engineering activities of CIE systems developments that are explained in chapter 3. Furthermore, to support the necessity of requirements engineering for human centred CIE systems development, the findings from semi-structured interviews are shown in a concept map that is also explained in this chapter. In chapter 5, requirements engineering is investigated from different angles to pick up the key issues from discrete research studies and practice such as traceability through process and product modelling, goal-oriented requirements engineering, the essential and incidental complexities in requirements models, the measurability of quality requirements, the fundamentals of requirements engineering, identifying and involving the stakeholders, reconciling software requirements and system architectures and barriers to the industrial uptake of requirements engineering. In addition, a comprehensive research study measuring the success of requirements engineering processes through a set of evaluation criteria is introduced. Finally, the key issues and the criteria are comparatively analyzed and evaluated in order to match each other and confirm the validity of the criteria for the evaluation and assessment of the requirements engineering implementation in the CIE case study projects in chapter 7 and the key issues will be used in chapter 9 to support the CMM (Capability Maturity Model) for acceptance and wider implications of the requirements engineering framework to be proposed in chapter 8. Chapter 6 explains and particularly focuses on how the requirements engineering activities in the case study projects were handled by highlighting strengths and weaknesses. This will also include the experiences and lessons learnt from these system development practices. The findings from these developments will also be utilized to support the justification of the necessity of a requirements engineering framework for the CIE systems developments. In particular, the following are addressed. • common and shared understanding in requirements engineering efforts, • continuous improvement, • outputs of requirement engineering • reflections and the critical analysis of the requirements engineering approaches in these practices. The premise of chapter 7 is to evaluate and assess the requirements engineering approaches in the CIE case study developments from multiple viewpoints in order to find out the strengths and the weaknesses in these requirements engineering processes. This evaluation will be mainly based on the set of criteria developed by the researchers and developers in the requirements engineering community in order to measure the success rate of the requirements engineering techniques after their implementation in the various system development projects. This set of criteria has already been introduced in chapter 5. This critical assessment includes conducting a questionnaire based survey and descriptive statistical analysis. In chapter 8, the requirements engineering techniques tested in the CIE case study developments are composed and compiled into a requirements engineering process in the light of the strengths and the weaknesses identified in the previous chapter through benchmarking with a Capability Maturity Model (CMM) to ensure that it has the required level of maturity for implementation in the CIE systems developments. As a result of this chapter, a framework for a generic requirements engineering process for CIE systems development will be proposed. In chapter 9, the authors will discuss the acceptance and the wider implications of the proposed framework of requirements engineering process using the CMM from chapter 8 and the key issues from chapter 5. Chapter 10 is the concluding chapter and it summarizes the findings and brings the book to a close with recommendations for the implementation of the Proposed RE framework and also prescribes a guideline as a way forward for better implementation of requirements engineering for successful developments of the CIE systems in the future

Data integration strategies for informing computational design in synthetic biology

PhD ThesisThe potential design space for biological systems is complex, vast and multidimensional. Therefore, effective large-scale synthetic biology requires computational design and simulation. By constraining this design space, the time- and cost-efficient design of biological systems can be facilitated. One way in which a tractable design space can be achieved is to use the extensive and growing amount of biological data available to inform the design process. By using existing knowledge design efforts can be focused on biologically plausible areas of design space. However, biological data is large, incomplete, heterogeneous, and noisy. Data must be integrated in a systematic fashion in order to maximise its benefit. To date, data integration has not been widely applied to design in synthetic biology. The aim of this project is to apply data integration techniques to facilitate the efficient design of novel biological systems. The specific focus is on the development and application of integration techniques for the design of genetic regulatory networks in the model bacterium Bacillus subtilis. A dataset was constructed by integrating data from a range of sources in order to capture existing knowledge about B. subtilis 168. The dataset is represented as a computationally-accessible, semantically-rich network which includes information concerning biological entities and their relationships. Also included are sequence-based features mined from the B. subtilis genome, which are a useful source of parts for synthetic biology. In addition, information about the interactions of these parts has been captured, in order to facilitate the construction of circuits with desired behaviours. This dataset was also modelled in the form of an ontology, providing a formal specification of parts and their interactions. The ontology is a major step towards the unification of the data required for modelling with a range of part catalogues specifically designed for synthetic biology. The data from the ontology is available to existing reasoners for implicit knowledge extraction. The ontology was applied to the automated identification of promoters, operators and coding sequences. Information from the ontology was also used to generate dynamic models of parts. The work described here contributed to the development of a formalism called Standard Virtual Parts (SVPs), which aims to represent models of biological parts in a standardised manner. SVPs comprise a mapping between biological parts and modular computational models. A genetic circuit designed at a part-level abstraction can be investigated in detail by analysing a circuit model composed of SVPs. The ontology was used to construct SVPs in the form of standard Systems Biology Markup Language models. These models are publicly available from a computationally-accessible repository, and include metadata which facilitates the computational composition of SVPs in order to create models of larger biological systems. To test a genetic circuit in vitro or in vivo, the genetics elements necessary to encode the enitites in the in silico model, and their associated behaviour, must be derived. Ultimately, this process results in the specification for synthesisable DNA sequence. For large models, particularly those that are produced computationally, the transformation process is challenging. To automate this process, a model-to-sequence conversion algorithm was developed. The algorithm was implemented as a Java application called MoSeC. Using MoSeC, both CellML and SBML models built with SVPs can be converted into DNA sequences ready to synthesise. Selection of the host bacterial cell for a synthetic genetic circuit is very important. In order not to interfere with the existing cellular machinery, orthogonal parts from other species are used since these parts are less likely to have undesired interactions with the host. In order to find orthogonal transcription factors (OTFs), and their target binding sequences, a subset of the data from the integrated B. subtilis dataset was used. B. subtilis gene regulatory networks were used to re-construct regulatory networks in closely related Bacillus species. The system, called BacillusRegNet, stores both experimental data for B. subtilis and homology predictions in other species. BacillusRegNet was mined to extract OTFs and their binding sequences, in order to facilitate the engineering of novel regulatory networks in other Bacillus species. Although the techniques presented here were demonstrated using B. subtilis, they can be applied to any other organism. The approaches and tools developed as part of this project demonstrate the utility of this novel integrated approach to synthetic biology.EPSRC: NSF: The Newcastle University School of Computing Science
