Resumen
When performing integration of several not uniformally precise signals of information systems one of the main problems consists in delimitation in which it is necessary to use this or that set of signals, and a way of fusion of signals. In article the method based on assessment of values of coordinates of the center of gravity of the resulting function of accessory of an indistinct system of a conclusion is considered. For determination of value of the center of gravity the following steps are used: the type of functions of accessory of entrances and exits of a system of an indistinct conclusion is set; borders of functions of accessory of entrances and exits of an indistinct system of a conclusion are entered; for functions of accessory of entrances the rated value of parameter of quality of information systems is set; for determination of coordinate of the center of gravity I. Mamdani's algorithm is used. According to the received trajectory of the center of gravity integration borders (border of operating modes) and the weight of information signals are defined. Change of a form of functions of accessory and the fields of their crossing (borders of operating modes) allows to change a form of a trajectory of the center of gravity from rated value of a signal with big variability concerning operating conditions, specifics of work of information systems, etc. thanks to what change of nature of scales of signals of information systems is possible. An example of integration of two information systems with different levels of a mean square deviation is reviewed, and it is shown that application of the method offered in article allows to receive as a result of integration a total signal with a mean square deviation smaller, than at the most exact kompleksiruyemy information system.
