| 概要≠ | Strategic Options Development and Analysis (SODA) is a facilitated, qualitative method for structuring complex organisational problems. Developed by Colin Eden in 1988, it uses cognitive maps — directed graphs of causal constructs — to capture and integrate the subjective views of multiple stakeholders. SODA is most valuable when decision makers face ill-defined, wicked problems where shared understanding must be built before any quantitative analysis can begin. | A fuzzy cognitive map, introduced by Bart Kosko in 1986, represents a system as a network of concepts connected by signed, weighted causal links, and simulates how the concepts influence one another over time. By combining the intuitive structure of a cognitive map with fuzzy weights and iterative activation, FCMs let experts encode causal knowledge and then run what-if scenarios — making them popular for policy analysis, strategic decision-making, and modelling complex socio-technical systems. |
