troduction to Multicriteria Decision AnalysisI n this chapter we focus on multicriteria decision making (MCDM). TheI terms multicriteria decision analysis and multicriteria decision analysis(MCDA) are used interchangeably. Broadly speaking, M CDM problems involve a set o f alternatives that are evaluated on the basis o f conflicting andincommensurate criteria. Criterion is considered a generic term that includesboth the concepts o f attribute and objective. Accordingly, two broad classeso f M CDM can be distinguished: MADM (multiattribute decision making) andM O D M (multiobjective decision making). Both MADM and M O D M problemsare further categorized into single-decision-maker problems and group decisionproblems. These two categories are, in turn, subdivided into deterministic,probabilistic, and fuzzy decisions. Deterministic decision problems assume thatthe required data and information are known with certainty and that there is aknown deterministic relationship between every decision and the correspondingdecision consequence. Probabilistic analysis deals with a decision situationunder uncertainty about the state o f problem’s environment and about therelationships between the decision and its consequences. Whereas probabilisticanalysis treats uncertainty as randomness, it is also appropriate to considerinherent imprecision ofinformation involved in decision making; fuzzy decisionanalysis deals with this type o f uncertainty. Conventional M CDM techniqueshave largely been aspatial in the sense that they assume a spatial homogeneitywithin the study area. This assumption is unrealistic in many decision situationsbecause the evaluation criteria vary across space. Consequently, there is a needfor an explicit representation o f the geographical dimension in MCDM. Thesecond part o f this chapter provides a framework for GIS-based (or spatial)multicriteria decision analysis. The framework integrates the GIS capabilitieso f data acquisition, storage, retrieval, manipulation, and analysis and the capabilities o f M CD M techniques for aggregating the geographical data and thedecision maker’s preferences into unidimensional values o f alternative decisions.8 1

When combining various objectives into course selection, it is critical to consider both personal interests and the acquisition of job-related skills. Multi-Criteria Decision Analysis (MCDA) and Weighted Scoring Models are two popular approaches for balancing these objectives. Firstly, multi-criteria decision analysis (MCDA) is a popular method for solving diverse choice issues through alternative evaluation, and it may be used to any subject that can specify a problem, alternatives, or criteria (Zlaugotne et al., 2020). When used to course selection, MCDA consists of multiple processes. Initially, criteria for assessing courses are established, which include elements such as interest level, relevance to work skills, difficulty, and career alignment. Weights are then allocated to each criterion based on its relative value. For example, personal interest may be more important than relation to professional skills. Courses are then evaluated on each criterion, usually using a standardized scale. For example, personal interest may be scored on a scale of 1 to 5, whereas relevance to work abilities could be assessed on a range of 1 to 10. Individual evaluations are combined using preset weights to get an overall score for each course. Finally, courses are sorted according to their total ratings, making it easier to identify the best possibilities for selection. Using this systematic method, MCDA allows decision-makers to properly balance many variables and make educated course selection decisions. Weighted Scoring Models provide an organized technique for evaluating courses using preset criteria and weighting elements. To adopt a weighted scoring model in course selection, various steps are taken. Initially, course evaluation criteria are created, including personal interest, work relevance, difficulty, and career alignment. Weights are then applied to each criterion based on its relative relevance, ensuring that the aggregate of weights equals 1 or 100%. Following that, each course is evaluated on each criterion using a standardized scale. These ratings are then multiplied by the corresponding weights for each criterion. Next, the weighted scores for each course are aggregated, resulting in a total score. Finally, courses are ranked based on their total scores, facilitating the identification of the most desirable options for selection. Through this methodical process, weighted scoring models enable decision-makers to prioritize courses effectively based on their alignment with key criteria. Considerations for evaluation play a crucial role in ensuring the effectiveness of the course selection process, particularly when integrating multiple objectives. Firstly, stakeholder involvement is essential, as including individuals such as students, advisors, and industry professionals allows for the identification of criteria and the assignment of weights that align with their preferences and goals. Additionally, maintaining data quality is paramount to

An attribute is used tomeasure performance in relation to an objective. The objective and underlyingattributes form a hierarchical structure o f evaluation criteria for a particulardecision problem. In this chapter we establish guidelines that facilitate theselection o f evaluation criteria (objectives and attributes). Both individual criterion and a set o f criteria should possess properties to adequately represent themulticriteria nature o f a decision problem. Each criterion must be comprehensive and measurable. A set o f criteria should be complete, operational, decomposable, nonredundant, and minimal. Once the hierarchical structure o f objectives and attributes is established, each criterion should be represented as amap layer in the GIS database. The set o f criterion maps is a representationo f a particular decision situation or a particular segment o f the real-worldgeographical system. Given the variety o f scales on which a criterion can bemeasured, multicriteria decision analysis requires that the values contained inthe various criterion map layers be transformable to comparable units. Anumber o f approaches can be used to make the criterion map layers comparable.The approaches are categorized into deterministic, probabilistic, and fuzzymethods.4 1 S E L E C T I N G E V A L U A T I O N C R I T E R I A4 .1 .1 Hierarchical Structure of Evaluation CriteriaAs suggested earlier, evaluation criterion is a generic term including both theconcepts of objectives and attributes (see Section 3.2).
