LRS-II: A Specialized Knowledge System for Launch Resource Scheduling.
Abstract
This research used the Level 5 expert system software to develop a specialized knowledge system called the Launch Resource Scheduling system (LRS-II). LRS-II will be used as a decision aid by USSPACECOM to determine if there is sufficient launch capability to meet future satellite requirements and to quickly assess the impact of contingencies such as launch or on-orbit failures. LRS-II uses multiple knowledge bases to match satellite launch requirements to available launch vehicles, launch pads, and upper stages. Specialized knowledge about satellite requirements and launch resources are stored in dBase III files. Level 5 knowledge base rules match specific fields of the satellite record against fields in the resource records to schedule the earliest launch resources that meet the satellite requirement. If two different types of launch vehicles are capable of launching a satellite, LRS-II selects the launch vehicle that meets the requirement earliest. If the satellite constellation allows multiple satellites on a single launch vehicle, specialized knowledge bases are executed to manifest the additional satellites. During manifesting, the constraints of satellite and resource availability, site processing time, shuttle mission duration, and satellite on-orbit checkout time are used to insure the selected launch date is accurate.
