  2. Issue-based information system - Wikipedia

    en.wikipedia.org/wiki/Issue-based_information_system

    IBIS was invented by Werner Kunz and Horst Rittel in the 1960s. According to Kunz and Rittel, "Issue-Based Information Systems (IBIS) are meant to support coordination and planning of political decision processes. IBIS guides the identification, structuring, and settling of issues raised by problem-solving groups, and provides information ...

    en.wikipedia.org/wiki/Closed-world_assumption

    Example. In the context of knowledge management, the closed-world assumption is used in at least two situations: (1) when the knowledge base is known to be complete (e.g., a corporate database containing records for every employee), and (2) when the knowledge base is known to be incomplete but a "best" definite answer must be derived from incomplete information.

  4. Ordered weighted averaging - Wikipedia

    en.wikipedia.org/wiki/Ordered_weighted_averaging

    Ordered weighted averaging. In applied mathematics, specifically in fuzzy logic, the ordered weighted averaging (OWA) operators provide a parameterized class of mean type aggregation operators. They were introduced by Ronald R. Yager. [1] [2] Many notable mean operators such as the max, arithmetic average, median and min, are members of this class.

  5. Type-1 OWA operators - Wikipedia

    The type-1 OWA operator with the weights shown in the top figure is used to aggregate the fuzzy sets (solide lines) in the bottom figure, and the dashed line is the aggregation result. Special cases. Any OWA operators, like maximum, minimum, mean operators; Join operators of (type-1) fuzzy sets, i.e., fuzzy maximum operators;

  6. Root cause analysis - Wikipedia

    en.wikipedia.org/wiki/Root_cause_analysis

    Root cause analysis. In science and engineering, root cause analysis ( RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants ...

  7. Systems analysis - Wikipedia

    en.wikipedia.org/wiki/Systems_analysis

    t. e. Systems analysis is "the process of studying a procedure or business to identify its goal and purposes and create systems and procedures that will efficiently achieve them". Another view sees systems analysis as a problem-solving technique that breaks a system down into its component pieces and analyses how well those parts work and ...

    en.wikipedia.org/wiki/Problem_solving

    Problem solving is the process of finding solutions to complex or challenging issues. It involves various skills, such as creativity, logic, analysis, and decision making. This article on Wikipedia provides an overview of different problem solving methods, models, techniques, and applications in various domains.

  9. Decision support system - Wikipedia

    en.wikipedia.org/wiki/Decision_support_system

    A decision support system (DSS) is an information system that supports business or organizational decision-making activities. DSSs serve the management, operations and planning levels of an organization (usually mid and higher management) and help people make decisions about problems that may be rapidly changing and not easily specified in advanceā€”i.e., unstructured and semi-structured ...
