Spaghetti diagram

The ultimate goal in reaction modeling is to discover the overall reaction that occurs within a system. Strangely, whereas the results of nearly every published study involving reaction modeling are presented in a spaghetti diagram (see, e.g., Fig. 13.1), few papers report the overall reaction. For this reason, some of the most... 

With more, admittedly tedious, work, every aspect of these spaghetti diagrams can be understood. And, much more interestingly, so can the electronic tuning of the NiAs - MnP -> NiP displacive transition.75 Now let s return to some simpler matters, concerning surfaces. 

Another mapping tool is needed in order to show the travel time of the materials and/or the people involved in the process. The tool for this analysis is referred to as the Spaghetti diagram. This is simply a floor plan of the area under consideration with lines showing the people movement or the materials movement for a particular process. With this diagram we can calculate travel time per part produced, and we can look at ways to reduce this travel time. 

The Spaghetti diagram for Z Base is shown on Chart 8.5. This shows the people travel time both before the Lean process and after the Lean changes were implemented. The reduction in movement is obvious. A similar diagram can be made for materials movement or any other type of physical movement that occurs in any area under consideration. 

This diagram has been described as looking like a plate of spaghetti with its interconnecting lines between elements of the model. Each element is fathomable and modelable, and therefore relatively simple, but the overall appearance seems to be complex.
