Support limit and capacity profiles for Resources #142

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Currently only a single upper & lower bound limit can be specified for 
resources.
It would be more useful to allow for a limit profile to be specified (so that 
the user can specify upper/lower limit bounds to change over time), common use 
cases:
- Initial Conditions reported by telemetry
- Vacation/sick time for crew members
- Downtime/repair time for machines.

This entails at least the following steps:
- Modify the resource API to allow the user to specify a limit profile
- Modify the resource data structures to keep track of the limit profile
- Modify Flaw and Violation detectors to use the limit profile instead of a 
single value

From Paul:

The Initial Conditions reported by telemetry use case is very important. 
 In fact, we may need to some capability like this to digest a faulty 
execution episode and do replanning.  In the AES project, we will be 
trying to integrate a diagnostic system with a planning system such as 
SPIFE/Europa.

However, I'm not sure specifying upper & lower bound limits captures 
this.  What is needed is a reset of the state or available amount of 
resource at specific fixed times.

the nddl/C++ API that I intend to put in place is something like this:

setLimit(resource,t,newLimitUb,newLimitLb);

that resets the limitUb/Lb starting at time t until the next specified limit 
(or until +inf if no other limit bounds are specified). The user can call 
setLimit as many times as necessary to fully specify the limit profile, only 
piecewise constant profiles will be supported initially.

Paul, if that doesn't seem to address your needs, let's discuss.
