Planning and Prosecution

The Planning and Prosecution SN leverages the capabilities of the integrated network of sensing, modeling and control resources and supports resource nesting and autonomy. It provides generalized resource planning and control activities that can be applied to plan, schedule, and prosecute multi-objective observational programs.

The Interactive Observatory Facility provides the services to design, assemble, and operate configurations of resources from across the OOI into unique systems for planning, testing and prosecuting observation requests, leveraging the nested and autonomous capabilities of the fully integrated network of sensing, modeling, and control resources. It provides experimentalists with services to define, compose, and schedule multi-instrument observations that can execute across the observatory utilizing the services provided by the Analysis and Synthesis SN for virtual collaboration management.

The Event Response Framework provides automated and expert (i.e., usually involving user intervention) review of events and processes that may result in responsive tasking or re-tasking of instrument and mobile resources, thus providing observation requests to the Resource Planner. It subscribes to rules governing resource usage and information on processes and events from the Data Management SN.

The Resource Planner is a solver based on a resource constraint model. The model abstractly represents resources through their state condition as well as activities that can be performed on the resources. For instance, an AUV’s state could consist of the battery charge condition, position, depth, and speed/energy profile. Activities for an AUV could include change position and depth or change to different behavior, such as “return-to-base” from “loitering”. The Resource Planner acts as a constraint solver that takes a resource request as input and results in a resource use plan as output.

The Plan Repository is a repository instance for storing and managing observation plans and behaviors. Observation plans in the repository can serve as templates that are modified when events response behavior is executed. The Resource Use Controller operates within the framework that the Resource Planner has determined.

The Resource Use Controller takes as input a resource use plan and a service agreement, and creates as output resource use plans or specific resource commands to trigger state change and activities in resources. In addition, the Resource Controller can defer the execution of resource use plans within a service agreement to a nested Resource Planner at a lower level.

The Fault Monitor is a separate component analyzing and overseeing resource status, providing fault analysis input to the Resource Use Controller that in turn can revise plans within their local service agreements or return to the Resource Planner for re-planning.

Autonomous Control provides connection points to local resources, controllers and processes aboard autonomous resource platforms such as AUVs or satellite-connected global moorings. Typically, available bandwidth is severely limited in these cases. Autonomous Control is the gateway to local processes that are not under direct control of the CI.
