In the context of Internet of Services (IoS), Service Based Applications are composed of a number of possibly independent services that are available in a network and provided by many actors under different conditions (like price, time to deliver, and so on).

Abstract
In the context of Internet of Services (IoS), Service Based Applications are composed of a number of possibly independent services that are available in a network and provided by many actors under different conditions (like price, time to deliver, and so on). Service provision conditions may change in time depending on provider policies, and as such they cannot be statically advertised together with the service description. In this paper we propose and investigate the possibility to use the chemical computational model to address the problem of finding compositions of services that satisfy time constraints coming from the structure of an abstract workflow against the time availability associated to each service component.File | Dimensione | Formato | |
