as below picture, In Plant simulation there is a little example "Layout Optimization",but I have one question about the example. I run the model and click the “start” button， it will give a optimized Layout ,but when I move a station position and run the model again and then I click the "start" button, I do not know why I will a new Layout (that is not same with that I run first )???. and I think Layout Optimization it will give a same Layout no matter the position of the station . can anyone know why , thank you very much
To get a more detailed impression on the module behaviour, it's maybe better a to start off with
a less complex model (s. below)
Left is before optimization , right is after optimization.
The path with the highest frequency has been minimized by swapping drain and sp1
the behavior of the simulation (i.e. throughput) is not changed by the optimization, but the distances between the material flow objects. The optimization determines a permutation of the locations of the stations, such that the costs of transport is minimal. The costs of transport is the product of transported amount of parts between two stations multiplied by the Euclidean distance of the locations. You can press the button Start on tab Optimization multiple times such that the cost are improved multiple times. The found optimized permutation is used as starting solution for the next optimization.
