    Sustainability management : insights from the viable system model

    A review of current literature on sustainability standards reveals a significant gap between their adoption and the implementation of sustainability into every level of the organisation. In this paper, it is argued that in order to overcome this challenge, an appropriate model of an organisation is needed. The Viable System Model (VSM) is proposed as such a model and, in order to illustrate this argument, it is used to interpret the ISO 26000 standard on Social Responsibility (SR). First, the VSM theory is introduced and presented by modelling the hypothetical company Widget Co. Then, the clauses of ISO 26000 are mapped on the Widget Co. model, together with detailed descriptions and examples on the organisational and managerial implications of its adopting the standard's guidelines. The result is the identification of generic SR functions that need to be performed by the various organisational governance systems, as well as their dynamic interrelations, thus clarifying implementation issues. Moreover, by identifying different SR management layers, VSM is suggested as a way forward to develop an integration model for SR issues and respective sustainability tools. Finally, a discussion is given on the implications of using this approach to integrate sustainability standards and the way this research contributes to recent developments in sustainability research

    Decision support system (DSS) is a well-established research and development area. Traditional isolated, stand-alone DSS has been recently facing new challenges. In order to improve the performance of DSS to meet the challenges, research has been actively carried out to develop integrated decision support systems (IDSS). This paper reviews the current research efforts with regard to the development of IDSS. The focus of the paper is on the integration aspect for IDSS through multiple perspectives, and the technologies that support this integration. More than 100 papers and software systems are discussed. Current research efforts and the development status of IDSS are explained, compared and classified. In addition, future trends and challenges in integration are outlined. The paper concludes that by addressing integration, better support will be provided to decision makers, with the expectation of both better decisions and improved decision making processes

    Business Parks - Theoretical Background

    Economic activities can take place in either a physically scattered manner or in proximity. Companies in physical proximity in a designated area form the business parks. A business park is a site that is designed for economic activities in the field of trade, industry and different commercial activities (IBIS 2002b) Business parks are agglomeration of companies in physical proximity. These features provide certain benefits. Local authorities favor the establishment of business parks to ensure intensive use of land and create strong business environments in their localities. In the private sector, companies receive various benefits from being part of the B. P. First, the agglomeration factor leads to decreased costs for common maintenance services. Secondly, parks with companies in similar sectors benefit from joined marketing activities and increased exposure. Thirdly, B.Ps embodies conditions for synergy between companies. Synergy can be based on activities such as sharing and exchanging of materials and streams, professional knowledge and expertise, etc.business park, growth, public funding

    Using Fuzzy Linguistic Representations to Provide Explanatory Semantics for Data Warehouses

    A data warehouse integrates large amounts of extracted and summarized data from multiple sources for direct querying and analysis. While it provides decision makers with easy access to such historical and aggregate data, the real meaning of the data has been ignored. For example, "whether a total sales amount 1,000 items indicates a good or bad sales performance" is still unclear. From the decision makers' point of view, the semantics rather than raw numbers which convey the meaning of the data is very important. In this paper, we explore the use of fuzzy technology to provide this semantics for the summarizations and aggregates developed in data warehousing systems. A three layered data warehouse semantic model, consisting of quantitative (numerical) summarization, qualitative (categorical) summarization, and quantifier summarization, is proposed for capturing and explicating the semantics of warehoused data. Based on the model, several algebraic operators are defined. We also extend the SQL language to allow for flexible queries against such enhanced data warehouses

    COLLABORATIVE PORTAL MODEL FOR INTERCULTURAL TEAMS KNOWLEDGE MANAGEMENT

    Get PDF
    In the multinational organizations, more groups of individuals are being involved in the process of knowledge creation in a collaborative manner, of sharing knowledge and learning from it. These individuals can have heterogeneous cultures and they must use a common language. IT has created and is developing the infrastructure for cross-cultural communications and intercultural knowledge management. Nowadays, intercultural knowledge management can be realized with support of Collaborative Technologies and Knowledge Management Support Systems (KMSS). In this respect Collaborative Technologies and Intercultural Knowledge Management Support Systems (IKMSS) will be the appropriate way for supporting intercultural communication, learning and collaborative knowledge management in organizations. In this paper we present a conceptual model of a collaborative portal for Intercultural Team Knowledge Management as a powerful support for increasing team’s performance.: collaborative support, collaboration, knowledge management, intercultural teams, intercultural knowledge management, intercultural knowledge management portal

    A robot swarm assisting a human fire-fighter

    Emergencies in industrial warehouses are a major concern for fire-fighters. The large dimensions, together with the development of dense smoke that drastically reduces visibility, represent major challenges. The GUARDIANS robot swarm is designed to assist fire-fighters in searching a large warehouse. In this paper we discuss the technology developed for a swarm of robots assisting fire-fighters. We explain the swarming algorithms that provide the functionality by which the robots react to and follow humans while no communication is required. Next we discuss the wireless communication system, which is a so-called mobile ad-hoc network. The communication network provides also the means to locate the robots and humans. Thus, the robot swarm is able to provide guidance information to the humans. Together with the fire-fighters we explored how the robot swarm should feed information back to the human fire-fighter. We have designed and experimented with interfaces for presenting swarm-based information to human beings
