A Use-Case Model for a Knowledge Management System to Facilitate Disaster Relief Operations

There are numerous disaster relief agencies poised to respond to disasters; however, coordinating the activities of these diverse and dispersed entities and capitalizing on their knowledge assets can be a challenge. All of these agencies are dedicated to serving survivors of disasters, but they at times lack the coordination necessary to respond efficiently. The Virginia Voluntary Organizations Active in Disaster (VOAD) is an umbrella organization of existing agencies dedicated to working closely with other organizations to improve service and minimize duplication during disaster operations. To better cope with disasters, the Virginia VOAD needs to develop knowledge management strategies to coordinate its resources. The goal of this study was to design a use-case model of a web-based knowledge management system to support state and local level disaster recovery planning and operations in the aftermath of a disaster. The focus of this study was to support the disaster field office (DFO) operations. The use-case methodology outlined in the Rational Unified Process and supported by the Unified Modeling Language notation provided the means of systematically discovering and documenting system requirements. The resulting model provides a framework for a knowledge management system that has been adapted to the disaster recovery domain. Evaluation and validation of the model has shown this to be a viable concept. It is anticipated that this model could serve as the basis for developing a prototype knowledge management system that may also be adapted to similar state and local VOAD chapters around the country

Manufacturing systems interoperability in dynamic change environments

The benefits of rapid i.e. nearly real time, data and information enabled decision making at all levels of a manufacturing enterprise are clearly documented: the ability to plan accurately, react quickly and even pre-empt situations can save industries billions of dollars in waste. As the pace of industry increases with automation and technology, so the need for accurate, data, information and knowledge increases. As the required pace of information collection, processing and exchange change so to do the challenges of achieving and maintaining interoperability as the systems develop: this thesis focuses on the particular challenge of interoperability between systems defined in different time frames, which may have very different terminology. This thesis is directed to improve the ability to assess the requirement for systems to interoperate, and their suitability to do so, as new systems emerge to support this need for change. In this thesis a novel solution concept is proposed that assesses the requirement and suitability of systems for interoperability. The solution concept provides a mechanism for describing systems consistently and unambiguously, even if they are developed in different timeframes. Having resolved the issue of semantic consistency through time the analysis of the systems against logical rules for system interoperability is then possible. The solution concept uses a Core Concept ontology as the foundation for a multi-level heavyweight ontology. The multiple level ontology allows increasing specificity (to ensure accuracy), while the heavyweight (i.e. computer interpretable) nature provides the semantic and logical, rigour required. A detailed investigation has been conducted to test the solution concept using a suitably dynamic environment: Manufacturing Systems, and in particular the emerging field of Manufacturing Intelligence Systems. A definitive definition for the Manufacturing Intelligence domain, constraining interoperability logic, and a multi-level domain ontology have been defined and used to successfully prove the Solution Concept. Using systems from different timeframes, the Solution concept testing successfully identified systems which needed to interoperate, whether they were suitable for interoperation and provided feedback on the reasons for unsuitability which were validated as correct against real world observations

Knowledge discovery for moderating collaborative projects

In today's global market environment, enterprises are increasingly turning towards collaboration in projects to leverage their resources, skills and expertise, and simultaneously address the challenges posed in diverse and competitive markets. Moderators, which are knowledge based systems have successfully been used to support collaborative teams by raising awareness of problems or conflicts. However, the functioning of a moderator is limited to the knowledge it has about the team members. Knowledge acquisition, learning and updating of knowledge are the major challenges for a Moderator's implementation. To address these challenges a Knowledge discOvery And daTa minINg inteGrated (KOATING) framework is presented for Moderators to enable them to continuously learn from the operational databases of the company and semi-automatically update the corresponding expert module. The architecture for the Universal Knowledge Moderator (UKM) shows how the existing moderators can be extended to support global manufacturing. A method for designing and developing the knowledge acquisition module of the Moderator for manual and semi-automatic update of knowledge is documented using the Unified Modelling Language (UML). UML has been used to explore the static structure and dynamic behaviour, and describe the system analysis, system design and system development aspects of the proposed KOATING framework. The proof of design has been presented using a case study for a collaborative project in the form of construction project supply chain. It has been shown that Moderators can "learn" by extracting various kinds of knowledge from Post Project Reports (PPRs) using different types of text mining techniques. Furthermore, it also proposed that the knowledge discovery integrated moderators can be used to support and enhance collaboration by identifying appropriate business opportunities and identifying corresponding partners for creation of a virtual organization. A case study is presented in the context of a UK based SME. Finally, this thesis concludes by summarizing the thesis, outlining its novelties and contributions, and recommending future research

An evaluation of information and communication technology application in South African construction industry

Abstract: The construction industry is evolving like other allied industries. New innovations are borne out of the quest to achieve more value for money, while also retaining a competitive edge in the international sphere. A comprehensive study on the application of information and communication technology (ICT) for construction work in South Africa, particularly the stages of construction work, is lacking. This study seeks to evalaute information and communication technology tools used for construction activities in the South Africa construction industry. The research evaluates the level of awareness of construction professionals as to the use of new ICT tools in the fourth industrial revolution era. It also discusses the ICT tools used at the planning stage of construction, the design and the construction stage. It employed the Professional Client/Consultants Service Agreement Committee (PROCSA) template but limited it to stage 0 to 5. It also discusses the challenges, drivers and benefits of using ICT tools for construction activities in South Africa. The primary data was collected through a questionnaire which was distributed online via Questionpro platform to South African construction professionals in Gauteng Province only. One hundred and fifty (150) questionnaires were distributed. One hundred and twenty (120) of the responses were valid and used for the analysis. This accounted for eighty per cent (80%) of the total survey. In ensuring the reliability of the research questionnaire, Cronbach's alpha coefficient reliability was conducted on the scaled research questions. Compare mean was used to address the level of awareness of ICT tools and ICT tools used at the planning, design, and construction stages. Factor analysis was used to analyze the factors which serve as challenges to, drivers of, and benefits of the effective use of ICT tools. The study revealed that professionals have different awareness levels of ICT tools. They are more aware of ICT tools that are the core of their professional duties. At the planning stage of construction work in South Africa, all professionals use design/estimation and simulation-based tool most. In the design stage, the most frequently used tools are the computer-based tools and the design/estimation-based tools which are used by engineers, architects, and construction project managers. At the construction stage, computer-based tools and administrative tools are the highest-ranked tools. The exploratory factor analysis revealed that the challenges to the use of ICT in the South African construction industry are classified into people, cost, standardization, and management-related problems. The measures to ensure the effective use of ICT tools for construction processes in South Africa are also grouped into user-related factors, ICT knowledge and end-uses. The benefits from the effective use of ICT tools for construction...M.Tech. (Construction Management
