A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
A reliability block diagram (RBD) is a diagrammatic method for showing how component reliability contributes to the success or failure of a redundant system. RBD is also known as a dependence diagram (DD). A reliability block diagram. An RBD is drawn as a series of blocks connected in parallel or series configuration. Parallel blocks indicate ...
In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. [1] [2]Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller matrices.
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
A functional block diagram, in systems engineering and software engineering, is a block diagram that describes the functions and interrelationships of a system. The functional block diagram can picture: [1] functions of a system pictured by blocks; input and output elements of a block pictured with lines; the relationships between the functions ...
This diagram type is also known as FMC Block Diagram; Dynamic Structure Diagram depicts processes that can be observed in a system. This diagram type is also known as FMC Petri-net; Value Range Structure Diagram depicts structures of values found in the system. This diagram type is also known as FMC E/R Diagram; All FMC diagrams are bipartite ...
For some authors, a linear signal-flow graph is more constrained than a block diagram, [35] in that the SFG rigorously describes linear algebraic equations represented by a directed graph. For other authors, linear block diagrams and linear signal-flow graphs are equivalent ways of depicting a system, and either can be used to solve the gain. [36]
The basic idea is to try to divide a system in such a way that each block of a block diagram can be described without an "and" or "or" in the description. This exercise forces each part of the system to have a pure function. When a system is designed as pure functions, they can be reused, or replaced.
