Service composition with partial goal satisfaction

IoT applications are often ad-hoc compositions of services offered by connected devices that cooperate to satisfy user's goals. Sometimes, addressing full goal satisfaction is too stringent and replacing that with an easier to satisfy partial goal satisfaction is a good alternative to a complete failure. In this paper we propose a service composition approach that adopts a metrics for measuring the partial satisfaction of goal. The metrics adopts an electrical analogy extended for dealing with temporal goals.
