    pecification of dependency areas in UML designs

    A concept of dependency areas can help in tracing an impact of artifacts of a project (requirements, elements of the UML design, extracts of the code) and assist in their evolution. The dependency area of an element of a UML design is a part of the design that is highly influenced by the given initial element. Dependency areas are identified using sets of propagation rules and strategies. Selection strategies control application of many, possible rules. Bounding strategies limit the number of elements assigned to the areas. This paper is devoted to the specification of the rules and strategies. They are specified using an extended UML meta-model and expressions in the Object Constraint Language (OCL)

    Construction collaboration: a QFD approach

    Get PDF
    The UK Construction industry is a wide ranging complex environment with constantly evolving cultural, technical and organisational dynamics. Collaboration systems are used within that environment to store information and aid construction professionals in dealing, manipulating and completing information vital to projects. There are many collaboration systems available to the construction market, but most are based on versions used in other less similar industries. As a result though the software packages available to work at a level acceptable to the major construction contractors, they are not fully satisfying the customers need. The quality of the software available currently could be improved. Quality Function Deployment (QFD) is a Japanese product development tool developed in the 1960s. It is a quality system for strategic competitiveness; it maximises positive quality that adds value; it seeks out spoken and unspoken customer requirements, translates them into technical requirements, prioritises them and directs the process to optimise those features that will bring the greatest competitive advantage. QFD has been applied largely anonymously to software in the United States of America, and sparingly to construction within the UK. Blitz QFD is a form of QFD that focuses specifically on the essential quality items of the customer. This method could be implemented within the construction industry creating a fully auditable transfer of customer needs to essential software design features. Blitz QFD would be a valuable development methodology in a construction industry that demands faster, user focused project collaboration software where the user's needs are not currently being satisfied

    MDSSF: a federated architecture for product procurement

    Get PDF
    In the AEC (Architecture / Engineering / Construction) industry, large construction projects are tackled by consortia of companies and individuals, who work collaboratively for the duration of the project. The consortia include design teams, product suppliers, contractors and inspection teams who must collaborate and conform to predefined scheduling constraints and standards. These projects are unique, complex and involve many participants from a number of organisations. Construction projects require consortia to procure supplies such as building materials and furniture from product suppliers. In large AEC projects, procurement of products, services and construction materials is an important and time consuming activity. Materials are sourced on a global basis from a large number of suppliers. The scale of the purchases made in large projects show that their procurement is a non-trivial exercise. Therefore, consortia members or the contractors require access to a large body of information about products or material information to aid procurement decision making. Web based communication and network technologies play an increasingly important role in supporting collaboration in AEC projects. However collaborative working in the construction industry is still restricted by the current limitations of network and communication technologies and their system architectures which are usually client/server based. The construction industry has been examining how the advancements in distributed computing technologies such as the Grid computing can remove some of the existing limitations and enhance collaboration. This research investigated how the procurement challenges such as accessing up-to-date product information available from a large number of products suppliers in an integrated manner using standard means could be addressed. A novel solution to the procurement challenges in the form of a distributed information sharing architecture is presented. The architecture uses the concepts of federated databases such as distribution of data and autonomy of databases and couples it with Grid computing to facilitate information exchange in a collaborative, coherent and integrated way to address the product procurement challenges
