    Content:Course Content:
    Fuzzy logic is an advanced computational technique which was developed to manage uncertain, approximate, vague data. Environmental data often involve imprecision (due to the natural variability of ecosystems), uncertainty (due to the incomplete knowledge on ecosystem functioning), qualitative information, subjective expert judgement. Fuzzy logic allows to deal with reasoning that is approximate rather than precise; instead of mathematical formulas, in fact, it uses linguistic rules. Fuzzy logic is able to quantify and manipulate uncertainty with mathematical rigor, thus it it represents a suitable, feasible and effective tool to deal with environmental issues.

    The course on applications of fuzzy logic to marine ecology research will focus on the following topics:
    • the different sources of subjectivity involved in ecological researches;
    • basics of classical (binary) logic: truth values, logical connectives;
    • basics of fuzzy logic and fuzzy sets theory: partial truth, membership functions, linguistic rules, interpretation of logical connectives in a fuzzy environment;
    • development of a fuzzy model: strategies of fuzzification, inference and defuzzification;
    • building expert systems with fuzzy logic; an example of development of index of ecological quality;
    • fuzzy clustering of ecological data
    • review of types of fuzzy applications to marine environmental research.
    Theoretical topics will be accompanied by practical examples, focused on study-cases of marine environmental research.
    Training experiences will also be included: students will be asked to develop fuzzy membership functions and linguistic rules, and to build fuzzy indices of ecological quality. Free software packages will be utilized during the training classes.
