Learn more. 68; 86]. Problem Structuring ☺ 3. Spatial extent of the study area: less than 500 km2, between 500 and 250,000 km2, between 250,000 and 1,500,000 km2, or above 1,500,000 km2. A weight is a value assigned to a criterion that indicates its relative importance with respect to the other criteria under consideration (Malczewski, 1999). Decision-Making in Forestry: A Review of the Hybridisation of Multiple Criteria and Group Decision-Making Methods. It can serve diverse purposes in supporting decision‐making, including providing structure to the debates between key actors, documenting the process of analysing the decision, making value judgements explicit, creating shared understanding and generating a sense of common purpose (DCLG, 2009, p. 111). The uncertainty assessment approach consists of four steps: uncertainty characterization, uncertainty analysis, local sensitivity analysis, and global sensitivity analysis. Sensitivity Analysis ☺ 6. International Journal of Biodiversity Science, Ecosystem Services & Management. To this end, their main results consisted of spatial clusters identifying areas with high biodiversity based on a set of criteria which were then crosschecked to see whether they overlap with existing protected areas in the region. Most of the articles addressed forest management and restoration (25%), conservation prioritization and planning (24%), and protected area planning and management (21%), while fewer dealt with mapping of biodiversity, wilderness and naturalness (8%). Can landscape‐scale approaches to conservation management resolve biodiversity‐ecosystem service trade‐offs? MCDM or MCDA are well-known acronyms for multiple-criteria decision-making and multiple-criteria decision analysis; Stanley Zionts helped popularizing the acronym with his 1979 article "MCDM – If not a Roman Numeral, then What? Suitability Mapping for Managed Aquifer Recharge: Development of Web-Tools. Criteria can be incommensurable, and expressed through different units of measurement: monetary values, number of new jobs, biophysical units, qualitative evaluations, etc. Multi‐criteria decision analysis (MCDA) is an effective knowledge synthesis method to support decision‐making, by systematically exploring the pros and cons of different alternatives (Beinat & Nijkamp, 1998; Geneletti & Ferretti, 2015; Linkov & Moberg, 2012). Prioritizing management strategies to achieve multiple outcomes in a globally significant Indonesian protected area. ", intended for an entrepreneurial audience. Other approaches included the Novel Approach to Imprecise Assessment and Decision Environments (NAIADE) [e.g. Decisi-o-rama: An open-source Python library for multi-attribute value/utility decision analysis. (2016), for example, the objective of the MCDA was to assess the effectiveness of existing environmental policies. In 16% of the MCDA, experts other than the authors were involved, for example, through Delphi techniques [e.g. 51]. To make it even simpler, let's use an example: You're trying to figure out which product feature your team should develop next, but there are plenty of criteria that need to be considered. The EVIDEM framework was developed to provide pragmatic multi-criteria decision support in health care, to estimate the value of healthcare interventions, and to aid in priority-setting. Decision‐making in nature conservation increasingly requires comparing alternatives to achieve multiple and competing goals, such as protecting habitats while addressing needs of vulnerable communities, and possibly fostering economic growth (e.g. Edition 2nd Edition . Multi‐criteria decision analysis (MCDA) is a method to support decision‐making, by exploring the balance between the pros and cons of different alternatives to accomplish a specific goal. MSU-NCRST-SEPP MEMPHIS-IN-MAY WORKSHOP May 6th –8th , 2009 Memphis-TN UNDERSTANDING SPATIAL MULTI‐CRITERIA DECISION MAKING an analytical … 47; 68]. Data ☺ 4. Multi-Criteria Decision Analysis book. Concerning decision, 45% of the articles provided only an overall ranking or suitability of alternatives, while 22% included additional rankings according to specific criterion, and 8% further analyses and clustering of stakeholders’ preferences. Multi-criteria decision analysis (MCDA) is increasingly used to support healthcare decision-making. Multi-criteria decision analysis (MCA) is a way for decision-makers (citizens or otherwise) to weigh up different options. Usually during deliberation, options are weighed up qualitatively, through discussion. Optimization of regional forest planning with multiple decision-makers. Sources of uncertainty in decision processes include measurement and conceptual errors, limited knowledge about process, simplification and data scarcity, and, above all, different values and opinions of stakeholders. A successful MCDA application should start by clearly establishing the decision context, defining the purpose of the MCDA and identifying the main actors to be involved in the process. While not exhaustive, the sample was, however, assumed sufficiently large to gain a good insight into the application of MCDA in nature conservation, and to allow investigating the three main stages of the MCDA process. Problem Identification and Formulation ☺ 2. Case Studies in Engineering and the Environment. Typical weighting techniques include trade‐off (Keeney & Raiffa, 1976), analytic hierarchic process (AHP; Saaty, 1980), swing (Von Winterfeldt & Edwards, 1986), random (Janssen, 2001), extreme weights (Janssen, 2001) and expected value (Janssen, 2001).

By presenting the integrated evaluation in a single score, the system with crop-livestock rotation (CLR) obtained a better performance. Multi-Criteria Decision Analysis. The second stage is the actual analysis, broadly consisting of: criteria assessment, weighting, criteria aggregation and sensitivity analysis (see Belton & Stewart, 2002; Munda, 1995; Roy, 1996). Operationally, it includes definition of the objectives of the decision process, identification of possible alternatives to achieve them and formulation of explicit criteria to assess how each alternative contributes to achieving the objectives. DOI link for Multi-Criteria Decision Analysis. The paper concludes by suggesting key elements of successful MCDA applications, including clear construction of the decision context; collaborative identification of alternatives and criteria that reflect the values at stake; adequate justification and communication of the methods for criteria assessment and weighting; reasoned choice of the criteria aggregation method, and comprehensive sensitivity analysis. Operationally, the review was carried out using the framework in Table 1, composed of questions and associated interpretation keys, representing the generalized MCDA process. Key Steps INTRODUCTION. We discuss the potential of MCDA in providing a framework for integrated valuation of ecosystem services. The Supporting Information provides details on the search queries. MCA enables the weighing of options to be carried out in a … Weighting was well‐addressed in the reviewed MCDA applications: the majority of the articles considered either single or multiple sets of weights, often defined together with stakeholders; only in few articles (2%) was weighting overlooked. About criteria selection, in 49% of the MCDA the authors formulated the criteria without input from stakeholders (see Figure 5 and Supporting Information). 27; 48], participatory meetings [e.g. In this respect, it is worth noticing that existing frameworks, such as the Common International Classification of Ecosystem Services (Haines‐Young & Potschin, 2013), could help to structure the objectives during or after an initial round of stakeholder involvement to define the problem. For example, a good structure avoids excessive and unbalanced number criteria for different objectives. Thus, MCDA is often integrated with other methods and tools, such as participatory approaches and Geographic Information Systems, as exemplified in Mustajoki et al. 82], and finally, 5% of the reviewed articles applied some ad hoc rules [e.g. Geographical region of and publication year. The basic idea of MCDA methods is to evaluate the performance of alternative courses of action (e.g. Making a Decision by Weighing Up Different Factors (Also known as Grid Analysis, Pugh Matrix Analysis, and Multi-Attribute Utility Theory) Imagine that your boss has put you in charge of taking on a new outsourced IT supplier. (2011) and Janssen, Knudsen, Todorova, and Hoşgör (2014). The Supplementary Information is archived in IRIS (see—the Research Registry of the University of Trento—an Open Access institutional archive, whose full‐text files are disseminated on the web and, following the publishers’ policies in terms of Open Access, are freely accessible by web users (as well as specialized harvesters) without any password or other types of identification. Emerging trends and research frontiers in spatial multicriteria analysis. Conceptually, it consists of two steps: providing “raw” information about the effects of each alternative on each criterion (e.g. This guide explains how multi-criteria decision analysis (or weighting and scoring) can be used to access a mix of both monetary and non-monetary benefits. Nevertheless, only a relatively small percentage of the reviewed articles engaged stakeholders in identifying alternatives and formulating criteria (15% and 35% respectively). Furthermore, weighted linear combination is a compensatory method, i.e. Alternatives include all types of options or courses of action to achieve a specific goal (Steinemann, 2001). ABSTRACT: Determining criteria weights is a problem that arises frequently in many multi-criteria decision-making (MCDM) techniques. The need for When t aking a decision, there might not always be a finite number of choices or there might be many alternatives to the original decision. 1; 10], PROMETHEE [e.g. By continuing you agree to the use of cookies. About criteria aggregation, the weighted linear combination was the most widely applied approach (63%), followed by AHP/analytic network process [e.g. This could be done by calculating a consistency ratio to measure how consistent the judgements have been relative to large samples of purely random judgements (Saaty, 1980). Moreover, it is important that a representative set of alternatives is considered, which includes all alternatives that are relevant for the stakeholders (Janssen et al., 2014). While not exhaustive, this sample can be considered sufficiently large to gain a useful insight into empirical applications of MCDA in nature and biodiversity conservation. A multitiered approach for grassland ecosystem services mapping and assessment: The Viva Grass tool. The Sustainable Management of Land and Fisheries Resources Using Multicriteria Techniques: A Meta-Analysis. The secondary data used in this paper consists of peer‐reviewed articles retrieved in the Scopus database. Concerning the definition of alternatives, 41% of the reviewed MCDA applications had no pre‐defined alternatives (see Figure 3); this includes studies aimed at selecting sites of biodiversity value suitable for protection or restoration [e.g. MCDA has previously been applied to a communicable disease priority setting in a number of countries of the European Union (EU) [3,4,5,6]. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Multicriteria decision-making and probabilistic weighing applied to sustainable assessment of beef life cycle. This tool is used by practically everyone in their daily lives. In the following sub‐section, we discuss our findings in the light of MCDA best practices and common pitfalls, providing recommendations for more effective applications in conservation. Multi-Criteria Decision Analysis. A lack of understanding of the meaning of weights, and of the way they may affect results is nevertheless a potential pitfall in MCDA. Both authors conceived the ideas and designed methodology; hence, collected and analysed the data; and, finally, contributed critically to the drafts and gave final approval for publication. Main objective of the MCDA process (may differ from the overall objective of the article). Any queries (other than missing content) should be directed to the corresponding author for the article. Tversky & Kahneman, 1981). (2017) and (Kurth et al., 2017). Pub. Multi-criteria decision analysis (MCDA) provides a framework by which these types of decisions can be made but, despite being used effectively in many fields, it is not often used in environmental management. As shown in Figure 2, the case studies were located in Europe (49%), Asia (17%), North America (13%), Africa (9%), South America (6%) and Australia/New Zealand (6%).

The weighted sum of the different chosen criteria is used to rank the options. Starting from a generalized MCDA process adapted from the literature, the review has two objectives. Finally, the remaining 11% of the articles addressed a diverse set of topics, ranging from siting of solar energy development in areas with low biodiversity value to designing railroad corridors minimizing biodiversity impacts. regional extent) and 33% covered an area of less than 500 km2 (i.e. Operationally, MCDA supports structuring decision problems, assessing the performance of alternatives across criteria, exploring trade‐offs, formulating a decision and testing its robustness. Identification of water reuse potential in Metropolitan Regions using the Analytic Hierarchy Process. About 24% considered already existing alternatives. In total, the articles covered 41 countries; the most represented countries being Italy (thirteen articles), UK (seven articles), USA (six articles), followed by Iran (five articles), Australia, Mexico and Spain (four articles each), and Finland, France and Sweden (three articles each), and the remaining 31 countries covered by one or two articles. The peculiarity of our study is that it applies a content‐based review, focusing on a narrower set of articles classified by their own authors as explicitly addressing nature and biodiversity conservation. The Multi-Actor Multi-Criteria Analysis (MAMCA) application in the Flemish long-term decision making process on mobility and logistics Transport Policy, Vol. These diverse purposes clearly emerged when examining individual studies in our review, as highlighted in the Supporting Information (Table S1, columns 5 and 12). with a firm commitment of resources). This problem needs to address and consider diverse factors such as economic, technical, environmental, social and political. It is most applicable to solving problems that are characterized as a choice among alternatives. Planning for Ecosystem Services in Cities. International Journal of Geographical Information Science. Keywords: multi-criteria decision analysis, multi-attribute decision analysis, weighted linear combination method, WLC, ordered weighted averaging method, OWA Received: July 8, 2009 Decision analysis can be defined as a set of systematic procedures for analysing complex decision problems. Multiple Criteria Decision Analysis (MCDA) methods, such as ELECTRE, PROMETEE, AHP, TOPSIS, VIKOR, have been applied to solving numerous real-life decision making problems in business and management. MCDA models were developed to assess various prevention and control decision criteria pertinent to a comprehensive management of Lyme … Applying Ecosystem Services to Support Planning Decisions: A Case Study. Multi-criteria analysis (MCA) provides a systematic approach for ranking adaptation options against a range of decision criteria. Overall, the reviewed articles covered five broad and not mutually exclusive topics. Broekhuizen H(1), IJzerman MJ(2), Hauber AB(3), Groothuis-Oudshoorn CGM(2). MCDA involves decision makers evaluating the alternatives under consideration based on the explicit weighting of criteria relevant to the overarching decision—in order to, depending on the application, rank (or prioritize) or choose between the alternatives. Only few articles included more information to support decision‐making. Use of Multi-Criteria Decision Analysis for Energy Planning 2 ABSTRACT This paper uses a Multi-Criteria Decision Analysis (MCDA) to examine tradeoffs in electricity generation technologies on the basis of cost, greenhouse gas emissions, water consumption, and land use. Analysis of data from 25 PCs from four brands, Toshiba, Dell, HP Compaq and Acer, presents the CPI. Among various weighting methods suggested in the decision literature, rank-based methods which convert a criteria ranking order into numerical weights have been claimed as a … In terms of geographic extent, 56% of the case studies covered an area between 500 and 250,000 km2 (i.e. Qualitative methods for ecologists and conservation scientists. Of the reviewed articles, 43% did not report about any sensitivity analysis. Special Feature: Qualitative methods for eliciting judgements for decision making, British Ecological Society, 42 Wharf Road, London, N1 7GS | T: +44 20 3994 8282 E: | Charity Registration Number: 281213. September 2019; Journal of Applied Sciences and Environmental Management 23(8):1449; DOI: 10.4314/jasem.v23i8.7. They mostly relied on literature reviews to justify the selection of the criteria. 2; 5]. The objectives, and related sub‐objectives, have to be characterized by a set of criteria and indicators that reflect the values associated with the consequences of each option. poor performance on some criteria can be compensated by better performance on other criteria. Expanding the role of social science in conservation through an engagement with philosophy, methodology, and methods. Our results show that in most MCDA applications (47%), the authors properly justified the step of criteria assessment, often by involving other stakeholders (22%). How are criteria assessed (i.e. Cassava farming practices and their agricultural and environmental impacts: a systematic map protocol. However, integrated assessments are lacking. Multi-Criteria Decision Analysis (MCDA) methods has been promoted as an alternative approach to monetary economic valuation of ecosystem services in Cost-Benefit Analysis framework (CBA). Multiple Criteria Decision Making. 41; 77], while in 26% and 17% the authors themselves assigned a single [e.g. Therefore, weights need to be handled with care, and the correct information about their meaning and implications needs to be conveyed to the actors involved (see Choo, Schoner, & Wedley, 1999). Multi‐criteria decision analysis ultimately aims to assist people in making decisions related to the objectives of the specific case study. In our sample of studies, consistency checks on weights was performed only in 14% of the cases. A Multiple-Criteria Decision Analysis (MCDA, or Multi-criteria analysis (MCA), is a decision-making analysis that evaluates multiple (conflicting) criteria as part of the decision-making process. park authorities, residents, tourist, entrepreneurs and researcher) to formulate and validate value functions through focus groups. This is to be followed by a collaborative identification of an inclusive set of alternative options to meet the desired objective. Multi‐criteria decision analysis (MCDA) is a method to support decision‐making, by exploring the balance between the pros and cons of different alternatives to accomplish a specific goal. Furthermore, weights should be assigned to account for the different degrees of importance of the criteria to the decision, considering different stakeholders’ perspective. ), but without any further conversion into a dimensionless preference scale. Finally, Marre et al. 18; 20] or forest modelling to simulate different management scenario [e.g. Multi-criteria decision analysis (MCDA) is increasingly used to support healthcare decision-making. Thus, they proposed a rather transparent approach to explicitly avoid undesired trade‐offs. 14; 79], and in 3% by consulting additional data sources [e.g. Establishment of an integrated decision-making method for planning the ecological restoration of terrestrial ecosystems. The better performance was due to the reduction in mechanization costs for planting and a high capacity of animal support per hectare without directly using phosphate and nitrogen fertilizers. The hierarchical arrangement of criteria deserves special attention, given that it affects stakeholders’ perception of the problem, and their capability to actually deal with it (see, for example, Retief, Morrison‐Saunders, Geneletti, & Pope, 2013; Weber, Eisenführ, & von Winterfeldt, 1988). More in general, prior to the selection of objectives and criteria, there ought to be a problem definition step aimed at identifying a decision question along with relevant decision‐makers, stakeholders and topic experts, ideally facilitated by an expert on participatory decision analysis (see, for example, Thorne et al., 2015). Mapping and assessment of cultural ecosystem services of Latvian coastal areas. It assists in framing decision problems, illustrating the per-formance of alternatives across criteria, exploring trade-offs, formulating a decision and testing its robustness. As Keeney (1992) puts it, the values of stakeholders should be at the core of the decision‐making, given that having explicit values makes it easier to define objectives, generate possible alternatives, compare them, and communicate and negotiate the results.
