2. Flow process chart - Wikipedia

   en.wikipedia.org/wiki/Flow_process_chart

   The first structured method for documenting process flow, e.g., in flow shop scheduling, the flow process chart, was introduced by Frank and Lillian Gilbreth to members of ASME in 1921 as the presentation "Process Charts, First Steps in Finding the One Best Way to Do Work". [2] The Gilbreths' tools quickly found their way into industrial ...

3. Process flow diagram - Wikipedia

   en.wikipedia.org/wiki/Process_flow_diagram

   A process flow diagram ( PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is ...

4. Material flow analysis - Wikipedia

   en.wikipedia.org/wiki/Material_flow_analysis

   Material flow analysis. Material flow analysis ( MFA ), also referred to as substance flow analysis ( SFA ), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of human activity on different spatial and temporal scales.

5. Value-stream mapping - Wikipedia

   en.wikipedia.org/wiki/Value-stream_mapping

   Value-stream mapping, also known as material- and information-flow mapping, [ 1] is a lean [ 2] -management method for analyzing the current state and designing a future state for the series of events that take a product or service from the beginning of the specific process until it reaches the customer. A value stream map is a visual [ 2] tool ...

6. Functional flow block diagram - Wikipedia

   en.wikipedia.org/wiki/Functional_flow_block_diagram

   A functional flow block diagram ( FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system 's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the ...

7. Sankey diagram - Wikipedia

   en.wikipedia.org/wiki/Sankey_diagram

   Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [ 1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property . Sankey diagrams can also visualize the energy accounts, material flow accounts on a ...

8. Flow diagram - Wikipedia

   en.wikipedia.org/wiki/Flow_diagram

   The term flow diagram is used in theory and practice in different meanings. Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process. For example the Information Graphics: A Comprehensive Illustrated Reference by Harris (1999) gives two separate definitions:

9. Piping and instrumentation diagram - Wikipedia

   en.wikipedia.org/wiki/Piping_and_instrumentation...

   A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...
