another better model about the staircase problem
Hi
A better version 6 that adds the calculation of the resting time in the elevator, especially if the starting time of the rest is close to the end of the climbing the elevator. It renames too most of the auxiliaries to initials, which is clearer. It calculates as initial the total time spent, showing that SD or capitalisation is not necessary to calculate it contrarily to the method used in the version 5. I have added another model version 7 with only two time-steps, that does not use any stock and where all the auxiliaries and stock of the version 5 are suppressed. The best way to use the model is with synthesim varying the ‘time starting the rest’ on the blue shadow variable. Both new models can be downloaded from the Vensim forum author LAUJJL.

Interesting. I haven't really absorbed this yet, but my approach is quite different. https://metasd.com/2022/02/escalator-solutions/
