FORWARD LOOKING DIAGNOSTICS

摘要

Forward Looking Diagnostics (FLD) approach is an assessment technique that provides a simplified way to determine overall condition of systems using the knowledge of their component/ equipment degradation. FLD was conceived to make it easier, faster and more economical to determine the type and severity of system level performance determination for a wide variety of operating modes.rnIn its short history, FLD has evolved from an informal network of loosely associated information utilized in techniques that apply only to simple or common cause failure events to a dynamic mechanism for collecting data and investigating complex failure modes from a variety of perspectives, alternatively dissecting them into their underlying (yet often unknown) root cause patterns. There seems to be almost no limit to the possible uses for FLD in the lifecycle support of complex electromechanical systems.rnLifecycle applications that can make use of FLD have several advantages over traditional prognostic-based failure determination methods. Among these are high cost, high uncertainty and single point type of failures, thereby making the use of FLD ever more necessary as systems become increasingly more complex over time.
