摘要:The term “diagnostics” is normally used to refer to the process of identifying some incorrectly operating components in a particular system. The fault symptoms are, however, usually discovered in a different part of the system than that in which the fault occurs. On those occasions when it is not possible to identify the source of the fault based on the principle of absolute logic, it is necessary to apply a formal procedure. This contribution presents a new methodology, by the means of an application systems approach, for diagnostics of management and organisational systems.
