An electronic circuit for use in providing computational decision-making capabilities. The circuit implements a hierarchy of decision-making cells, with outputs derived from input signals supplying argument values, configuration signals for controlling the decision making model and wires between cells defining relationships between cells that modify the decision-making model of dependent cells. The cells are primarily characterized by modified values that may represent outputs although they may have a variety of other function features such as importance values and threshold values. The arguments are characterized by argument values that may represent inputs. The arguments are associated with particular cells and the values of the arguments associated with a given cell are combined to determine the value of that cell. The wires between different cells define different types of functional relationships between them. Circuits are developed through the creation and manipulation of the graphical items of the interface using visually oriented processes such as drop down windows and drag and drop techniques.
