Automated derivation of complex system constraints from user requirements

International Space Station (ISS) payload developers submit their payload science requirements for the development of on-board execution timelines. The ISS systems required to execute the payload science operations must be represented as constraints for the execution timeline. Payload developers use a software application, user requirements collection (URC), to submit their requirements by selecting a simplified representation of ISS system constraints. To fully represent the complex ISS systems, the constraints require a level of detail that is beyond the insight of the payload developer. To provide the complex representation of the ISS system constraints, HOSC operations personnel, specifically the payload activity requirements coordinators (PARC), manually translate the payload developers´ simplified constraints into detailed ISS system constraints used for scheduling the payload activities in the consolidated planning system (CPS). This paper describes the implementation for a software application, user requirements integration (URI), developed to automate the manual ISS constraint translation process
