A reliability block diagram (RBD) is a drawing and calculation tool used to model complex systems. An RBD is a series of images (blocks) representing portions of a system. Once the images (blocks) are configured properly and image data is provided, the failure rate, MTBF, reliability, and availability of the system can be calculated.

Reliability engineering is a sub-discipline of systems engineering that emphasizes dependability in the lifecycle management of a product.Dependability, or reliability, describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or ...

ENHANCING TREATMENT PLANT RESILIENCE USING RELIABILITY BLOCK DIAGRAM MODELLING Simon Siow South East Water, Melbourne, VIC ABSTRACT This paper advances the state of practice for the asset management of complex water facilities. South East Water has piloted the use of Reliability Block Diagram (RBD) Modelling and has gained
A Reliability Block Diagram (RBD) is a graphical representation of the reliability dependence of a system on its components. It is a directed, acyclic graph. Each path through the graph represents a subset of system components. As long as the components in that path are operational, the system is …
Abstract: The use of commercially available software for analyzing reliability block diagrams (RBD) has become the rule for the vast majority of reliability analysts and engineers. After a model has been developed and checked, a software package is generally used to evaluate the model.
Software reliability is a special aspect of reliability engineering. System reliability, by definition, includes all parts of the system, including hardware, software, supporting infrastructure (including critical external interfaces), operators and procedures. Traditionally, reliability engineering focuses on critical hardware parts of the system.

The general approach is to capture the modeling effort with the use of Reliability Block Diagrams. The image to the right (click image) illustrates how a more complex system's configuration maybe represented by a Reliability Block Diagram. For each system the mission profile or usage profile varies.

Using Reliability Block Diagrams to Analyze Dependent and Independent Failure Modes. Note: This article has been updated to reflect the enhancements made in BlockSim 7 and ALTA 7. BlockSim 7 now features more realistic simulations and flexible system modeling than ever before.
In each case appropriate reliability analysis technique is applied (failure mode and effect analysis, reliability block diagrams or fault trees, dependence modelling).
At the very least, a reliability block must include information as to how this item fails (i.e., the reliability model of the block). Once the blocks' properties have been defined, the blocks can then be connected in a reliability-wise manner to create a reliability block diagram for the system.
A reliability block diagram is a graphical and mathematical model of the elements of a system permitting the calculation of system reliability given the reliability of the elements. The model reflects the reliability performance structure including series, parallel, standby and other arrangements of …

Block Diagram Model (same as Reliability Block Diagram Models)-What: Reliability block diagram (RBD) ... Reliability tools are used from stem to stern to demonstrate high reliability (the absence of failures for long periods of time) by use of many tools such as:
Taking Reliability Block Diagrams to the Next Level Using RBDs to model different systems and circumstances In the previous post, the basics of a Reliability Block Diagram were covered using simple Series or Parallel paths.
The purpose for quantitative reliability measurements is to define the rate of failure relative to time and to model that failure rate in a mathematical distribution for the purpose of understanding the quantitative aspects of failure. The most basic building block is the failure rate, which is estimated using the following equation: Where:
Reliability Block Diagrams (RBD) Often depicting elements within a system as a block within a diagram, RBD models provide a graphical and mathematical model of the system reliability given the reliability and relationships of the elements within the system.
A Reliability Block Diagram is a method of modeling how components and sub-system failures combine to cause system failure. Reliability block diagrams may be analyzed to predict the availability of a system and determined the critical components from a reliability viewpoint.
5.0 HARDWARE/SOFTWARE SYSTEM RELIABILITY MODELING Reliability modeling of combined hardware and software systems is in many ways analogous to reliability modeling of purely hardware systems. Reliability block diagrams of system elements are developed and employed. Individual hardware platforms and the software assigned to those platforms
