TIME-DEPENDENT SYSTEM KNOWLEDGE REPRESENTATION BASED ON DYNAMIC MASTER LOGIC DIAGRAMS

In this paper, the Dynamic Master Logic Diagram (DMLD) is introduced f or representing the time-dependent behavior of complex physical system s (feedback, time-lagged dependency, autocorrelation, trend, etc.). Ex perts may decompose a complex system hierarchically, and model the dyn amic behavior of its subsystems and components separately from each ot her. A DMLD is a hierarchical structure which enables a user to decomp ose a dynamic system into dynamically stable and independent subsystem s. Using a DMLD, degree of success (or failure), approximate full-scal e system physical values, and transition effects in the system can be used. An example of using DMLD for controlling a dynamic system is pre sented.
