I'm using Drools for a system of alarms on agriculture. I am considering several parcels, whose plants can be on different status (for example, sprouting, flowering, etc.). These statuses are updated automatically by rules, controled by several calendars. In the other hand, the farmer is allowed to change the plants' status by hand if he/she observes that real plants are in a status in the terrain. If the farmer set the status before the automatic change, there is no problem: the rules corresponding to the new state become active and the automatic change has no effect. But if the farmer changed the status after the automatic change, how would I consider the events in the period of time between automatic and hand changes?

Thanks in advance. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Reasoning-with-past-e...

The system is receiving readings from real sensors of humidity, temperature, etc.. There are a lot of rules for deciding if a specific plague or illness affects (or can affect) to the plants or not: One condition of those rules is the plants' status, because the illnesses affect to the plant depending on its status. I have defined Status, Reading and Risk as events. Well. Supose than the system has just passed from status "A" to status "B", and after that, it has received several readings from sensors whose values are a risk for an illness in the status "A" but not in "B". Then, the system has not activated the Risk, because it thinks that the current status is "B". Therefore, if the farmer inserts an status "B" after those readings, the system has not activated the Risk but that readings are dangerous. In that case, how do i say that there is a Risk?
