Decision Support Process

The Swedish research programme Urban Water has developed a concept of a multi-criteria basis intended to support decision-making for urban water and wastewater systems. Five criteria groups were established for sustainability assessment of urban water systems: Health and Hygiene, Environment, Economy, Socio-culture, and Technology. Each criterion requires a set of indicators corresponding to quantifiable facts and figures, or qualitative data to comparatively assess the different alternatives in the decision process. The decision support process starts as a baseline study where the existing conditions are addressed. Alternative strategies of the future urban water system are developed and analysed by different tools and methodologies in assessing the five criteria groups. Eventually, the results and conclusions are integrated and synthesised into a basis for decision-making. As an example of a decision support basis for chemical safety, a barrier perspective was introduced to find out if and to what extent hazardous substances can be stopped, diverged, or transformed at various points in the wastewater system. A set of barriers was suggested, i.e. behaviour, systems design, process design, optional recipients, and organisational. The barrier approach was applied to two alternative municipal wastewater system designs – a combined wastewater system vs. a source separated system – analysing the fate of phosphorus, cadmium, and triclosan. The study showed that the combined system caused a higher substance flow to the receiving waterbody than the separated system. The combined system also brought more phosphorus and cadmium to the farmland than the separated system, but only half the amount of triclosan.

In this paper, two fundamentally different urban wastewater systems are assessed from an environmental impact perspective. One system represents a centralised, high-tech, end-of-pipe structure whereas the second system is primarily based on source-separation strategies. Using material flow analysis in combination with evaluation methods based on life-cycle assessment the systems are evaluated by means of simulation and the results are discussed. A set of priority indicators for environmental assessments of urban water systems is suggested and applied in the analysis. Energy issues are also commented upon. The main intent of the paper is to present the principles of this type of assessment rather than detailed numbers for all possible environmental effects and hazardous substances emitted to air, water and soil. It represents one of several building blocks for a future multi-criteria decision-support system to evaluate urban water management from a sustainability perspective.

There is an increasing demand for active public involvement in forestry decision making, but there are as yet few established models for achieving this in the new sustainable forest management (SFM) context. At the level of the working forest, the fields of forest sustainability assessment, public participation, decision support, and computer technology in spatial modelling and visualization need to be integrated. This paper presents the results of a literature review of public participation and decision-support methods, with emphasis on case study examples in participatory decision support. These suggest that emerging methods, such as public multicriteria analysis of alternative forest management scenarios and allied tools, may lend themselves to public processes addressing sustainability criteria and indicators. The paper develops a conceptual framework for participatory decision support to address the special needs of SFM in tactical planning at the landscape level. This framework consists of principles, process criteria, and preliminary guidelines for designing and evaluating SFM planning processes with community input. More well-documented studies are needed to develop comprehensive, engaging, open, and accountable processes that support informed decision making in forest management, and to strengthen guidance for managers.

This paper describes a major program of research by the Commonwealth Scientific and Industrial Research Organization (CSIRO) into urban water, wastewater and stormwater services. The intent of the program has been to identify opportunities for achieving more sustainable urban water services. The term “sustainable” has been interpreted to mean improvements in environmental and economic performance of systems which maintain inter- and intragenerational equity. It is evident from the conclusions of the feasibility stage of the Urban Water Program that such opportunities exist, particularly with regard to the design and configuration of water and wastewater systems. The structure of the UWP is described and examples of critical outcomes given.

A methodology for using rough sets theory for preference modeling in decision problem is presented in this paper. We will introduce a new method where neural network systems and rough sets theory are completely integrated into a hybrid system and are used cooperatively for decision and classification support. At the first glance, the two methods we discuss have not much in common. But, in spite of the differences between them, it is interesting to try to incorporate both into one combined system, and apply it in the building of a decision support system.

This article highlights various features of risk and resilience standard developed by the ASME-ITI and American Water Works Association. The American Water Works Association and ASME Innovative Technologies Institute have jointly developed an American National Standard to enhance the security and resilience of drinking water and wastewater systems. The ASME-ITI, under the Department of Homeland Security’s sponsorship, initiated discussions with the water sector to consider the development of sector-level guidance based on RAMCAP Plus. The RAMCAP Plus process is composed of seven interrelated analytic steps, which provides a foundation for data collection and interpretation, analysis, and decision making valuable for understanding and managing risk and resilience. The process is designed to guide the selection of options that reduce risk and increase resilience, including informing funding decisions. The joint standard fulfils the need identified in the water sector-specific plan. It facilitates the reduction of risk and the enhancement of resilience at water and wastewater systems across America.

The revitalization of Toronto’s waterfront presents the largest urban redevelopment project currently underway in North America. With respect to planning the waterfront’s urban water systems (UWS), a number of studies considered a range of criteria in search for sustainable alternatives. However, a comprehensive assessment of the integrated source-drinking-wastewater-stormwater systems over their life cycles has not been developed. According to the main postulates of the integrated approach, hybrid water systems can offer potentially more sustainable solutions than traditional centralized systems. This paper discusses the development process of a decision support tool designed to facilitate evaluation of alternatives based on UWS metabolism concept while addressing some typical challenges of hydroinformatics. This decision-making support tool analyses and compares the sustainability performance of alternative decentralized solutions against a baseline conventional approach on a neighbourhood level. The tool uses a set of criteria, adopted by the large group of stakeholders involved in the development process, that are not typically considered in the decision-making process, such as energy savings, greenhouse gas (GHG) emissions, climate change resiliency, chemical use, and nutrient recovery.

Introduction. The article is devoted to the study of the features of managerial decision-making in complex socio-economic systems in the context of fire and rescue units management. The article deals with the decomposition of the decision-making process into the main elements and provides a thematic analysis of each of them. The author's classification of decision-makers on the fire from among the main positions and non-regular officials of the garrison is presented. The tasks of the research are to analyze the current state of the basic conceptual apparatus of the theory of decision support in the management of fire protection units and to formulate the most general approach to the definition of the decision support process. Methods. The analysis of Russian- and English-language literary, normative and statistical sources of information on the topic under consideration is carried out. The result of the decomposition and synthesis of the analyzed information is tables, figures and diagrams, as well as explanations to them. The author also compares the approaches to decision-making from the Russian-language management theory with the results of empirical studies conducted abroad. Results and discussion. A theoretical review of the basic provisions of the theory of decision support with an appeal to the features inherent in the process of managing fire protection units is carried out. The author presents the results of a retrospective analysis of the development of approaches to the definition of the concepts of "decision support system" and "management support", as well as the definition of the term "support of decision making". Conclusions. Based on the results of the study, a hypothesis is formulated that at the stage of development of specialized decision support systems for decision makers, a synthesis between different approaches will remain.
