Can a cause and effect diagram be used in the design of complex machinery?

Can a cause and effect diagram be used in the design of complex machinery?

(OP)
I understand cause and effect diagrams can be used as input to write software for simple applications. What about more complex applications/machinery? What to use than? A control narrative/philosopy?

RE: Can a cause and effect diagram be used in the design of complex machinery?

Howdy Ken,
I routinely use a Boolean-style logic diagram for more complex logic. Yes, it does take time to develop, but I have yet to find better way to transfer my thoughts to the programmer.

RE: Can a cause and effect diagram be used in the design of complex machinery?

Hi GG,

I like that style of presentation too. I first met it when I started working on Westinghouse turbines and generators. Somewhere I have a fairly full Autocad library of digital logic symbols, analogue blocks, etc. if that's of any interest?

RE: Can a cause and effect diagram be used in the design of complex machinery?

i used that format when i was doing work for P&G projects. I must of made like 10000 of these diagrams on 1 project, painful memory. I think they were called Boolean logic diagrams. All the most complex function blocks was basically what the plc manufacturer put out as a block diagram.

RE: Can a cause and effect diagram be used in the design of complex machinery?

Cause and effect diagrams are unlikely to adequately capture nuances of timing, multiple events, and conditional events.

Logic diagrams can be translated into something like VHDL, which would be roughly equivalent to pseudo-code. If the diagrams are done in a suitable CAD program, VDHL essentially comes automatically.
