An oven (aka batch delay) can be seen as an idealized model of a batch process, e.g., cookies are put on a baking tray, the oven is loaded, the cookies are baked for some time, and finally the oven is unloaded (the process may then start over again).

The parameters or inputs batchSize, maxLoadingTime, processingTime, and setupTime specify the behavior of the batch process. The oven is loaded by a flow connected to its inflow port (usually from a cloud or another stock representing a buffer stock) until either the batchSize is reached (the oven's capacity) or the time since the loading of the oven commenced has reached the maxLoadingTime. It will then close and prevent further inflow for the duration of the processingTime. The unloading of the finished "material" will take place in dt time - a global variable that indicates the shortest possible durationa of any process in a model. The reloading can commence after setupTime has passed since the process has ended. For setupTime = 0 simulatenous loading and unloading will take place.

To initialize the oven, an initialLoad and an initialLoadingTime (e.g., how much time has already passed loading the oven when the simulation starts) have to be given.

Notes

• Care has to be taking in the case of simultaneous loading and unloading as in the case of the loading rate being higher than the unloading rate the capacity could be reached before the unloading is done so that material would be processed twice.


• batchSize, maxLoadingTime, processingTime, and setupTime can be time-varying continuous inputs, but are internally recalculated every time the process starts and then are held fixed.
