modelWang2005Occupancy
A model to predict Occupancy of a single person office
Extends from Modelica.Blocks.Icons.DiscreteBlock (Graphical layout of discrete block component icon).
Information
Model predicting the occupancy of a single person office.
References
The model is documented in the paper "Wang, D., Federspiel, C.C. and Rubinstein, F., 2005. Modeling occupancy in single person offices. Energy and buildings, 37(2), pp.121-126."
The model parameters are regressed from a field study in California with 35 single person offices at a large office building from 12/29/1998 to 12/20/1999.

Refactored implementation of random number calculations, transfering the local state of the random number generator from one call to the next.
This is for #4069. -

Reformulated model so it works also if the simulation does not start at 0.
To improve efficiency, this reformulation also changes the event triggering function so that it leads to time events rather than state events.
This is for #2590. -

First implementation.
