Integration of decision support systems to improve decision support performance

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

Telecommunications forecast for ITU Region 2 to the year 1995

Telecommunications activity was studied. The primary objective was to forecast the need for fixed service satellites (FSS) by countries within ITU Region 2 excluding the United States and Greenland. Forecasts of telecommunications equipment needs were developed as a yardstick of the relative level of telecommunications activity among developing countries within the region. A likely scenario for the implementation of domestic and regional communications satellites is forecasted to provide services to and among countries in ITU Region 2. By 1995, it is forecast that 15 fixed service satellites will be implemented. A forecast of the countries requirements indicates that, with the possible exception of Canada, this constellation of satellites will meet these countries' needs to beyond the year 2000

Environmental sustainability conducts and corporate performance in extractive sector

The subject of environmental sustainability transcends geographical zones, it attracts attention at the top-most business, governmental and civil society levels because of its current visible impacts. Despite the growing concern for a sustainable ecosystem, few applied studies have been conducted to establish the relationship between environmental sustainability and corporate performance in the extractive sector (one of the most profitable of all business sectors, yet arguably the worst culprit in environmental degradation). Therefore, this research seeks to explore the relationship between environmental sustainability and corporate performance in the extractive sector. This relationship was investigated using data from 68 companies within the extractive sector in both Europe and the Americas by the technique of multiple linear regression and event studies by one-way ANOVA. Our results show a negative relationship between environmental sustainability and profit while mixed results were obtained for relationship between environmental sustainability and firm value. In the short horizon, there is a positive relationship between environmental sustainability and firm value while a negative result was obtained in a long-horizon. The pattern of the results is most likely due to the unique nature of the sector where the demand for product exceeds supply. There is monopoly power in the form of cartels, and substitutes for the sector’s products (e.g. oil, gas, and cement) are either unavailable or inadequate. Therefore, poor attention to environmental responsibilities may not necessarily affect the profit but impact negatively on corporate value of the companies within the sector in a short-term. However, in the long-term, poor sensitivity to the environment may not be sustainable

Towards the realisation of an integratated decision support environment for organisational decision making

Traditional decision support systems are based on the paradigm of a single decision maker working at a stand‐alone computer or terminal who has a specific decision to make with a specific goal in mind. Organizational decision support systems aim to support decision makers at all levels of an organization (from executive, middle management managers to operators), who have a variety of decisions to make, with different priorities, often in a distributed and dynamic environment. Such systems need to be designed and developed with extra functionality to meet the challenges such as collaborative working. This paper proposes an Integrated Decision Support Environment (IDSE) for organizational decision making. The IDSE distinguishes itself from traditional decision support systems in that it can flexibly configure and re‐configure its functions to support various decision applications. IDSE is an open software platform which allows its users to define their own decision processes and choose their own exiting decision tools to be integrated into the platform. The IDSE is designed and developed based on distributed client/server networking, with a multi‐tier integration framework for consistent information exchange and sharing, seamless process co‐ordination and synchronisation, and quick access to packaged and legacy systems. The prototype of the IDSE demonstrates good performance in agile response to fast changing decision situations

Strategies for the Development of IT Disaster Recovery Plans in the Manufacturing Industry

Information technology (IT) leaders have reported technology disruptions because of natural disasters, terror attacks, or adversarial threats. Information technology leaders are concerned with technology disruptions, as these disruptions are costing organizations as much as $22,000 per minute. Grounded in Zachman’s framework, the purpose of this qualitative multiple case study was to explore strategies IT managers in the manufacturing industry use to develop IT disaster recovery (DR) plans to support business operations. The participants included 3 manufacturing IT professionals, 2 Department of Defense manufacturing infrastructure specialists, and 1outsourcing contractor, each from firms located in the central United States who successfully developed IT DR plans to support business operations. Data collection comprised of interviews and documentation. I used Braun and Clarke’s (2006) six-step process for thematic analysis to identify 5 themes: contingency planning by priority, testing plans, levels of recovery, time requirements for recovery, and costs associations. The implications for positive social change include the potential for IT managers and leaders to contribute to strategic development of IT DR plans and prevent economic disruption for consumers, communities, and society during disaster events

Integrating EJ into Federal Policies and Programs: Examining the Role of Regulatory Impact Analyses and Environmental Impact Statements

Following Executive Order 12898 in 1994, federal agencies have taken a variety of steps to incorporate environmental justice (EJ) into their programs and practices. Two scales at which these efforts are critical are regulatory design and enforcement. This study evaluates Regulatory Impact Analyses (RIAs) and Environmental Impact Statements (EISs) across three federal agencies (the Department of Energy, the Department of Transportation, and the Environmental Protection Agency) to compare the extent to which EJ is addressed at these two scales, across agencies, and over time. By searching agency documents for key EJ variables, such as site, population, and impact characteristics, we develop a framework to determine if RIAs and EISs include sufficient information to identify disproportionate impacts of proposed regulations or projects on minority and low-income communities. Results of this analysis reveal that EJ issues are noted more frequently in all three agencies’ EISs over time, but few RIAs or EISs contain enough data to assess whether EJ impacts are significant.environmental justice, Regulatory Impact Analysis, RIA, Environmental Impact Statement, EIS, content analysis, program evaluation

The Egnatia Motorway and The Changes in Interregional Trade in Greece: An Ex Ante Assessment

The Egnatia Motorway, located in the northern part of Greece, constitutes one of the most important, as well as ambitious, projects of the Trans-European Transport Networks programme (TETN) funded by the European Commission. It is expected to greatly influence the spatial economic relationships of several regions across the country. The motorway crosses all administrative regions of Northern Greece, and the expectations currently sustained by the public as regards its contribution to regional development are exceptionally great. As numerous empirical studies have already shown, the most important changes in regional economy induced by interregional transportation infrastructure are associated with trade flows between different regions. This paper analyses the major determinants of interregional trade in Greece and estimates the changes in interregional trade flows which the construction of the Egnatia Motorway is capable of generating
