Description
OBJECTIVES:
One of the daunting challenges astronauts face on long-duration exploration missions (LDEMs) is the need for the crew to perform tasks with greater autonomy than crewmembers face in low-Earth orbit (LEO). With increased distance, crewmembers face significant lag between communications with Mission Control Center (MCC). As a result of this lag, crewmembers will have more timely access to information regarding executing tasks and activities in response to disturbances than MCC. The lag in communication and success of LDEMs will require that crew be able to reschedule their own timeline without creating violations regarding the availability of resources, time, and the sequential requirements of activities.

In practice, planning and scheduling remain largely manual tasks due to limitations of the analytic and heuristic methods used to automate and optimize schedules using mathematical models. Human schedulers benefit from their flexible, adaptive, and creative capabilities. However, their success is often limited by the amount of information humans can simultaneously consider during scheduling. Developing human-computer interactive approaches may allow schedulers to mitigate these weaknesses, but many important questions remain to be answered. Time will be an extremely important factor in managing space exploration mission schedules and, yet, there is little research quantifying schedule performance using time as a criterion.

The goal of this Human Capabilities Assessments for Autonomous Missions (HCAAM) Virtual NASA Specialized Center of Research (VNSCOR) study is to quantify crew performance for self-scheduling using Playbook scheduling software according to the following aims.
1) Quantify crew performance envelop for the task of self-scheduling space flight operational plans,
2) Develop countermeasures to mitigate deficient crew self-scheduling performance,
3) Validate self-scheduling countermeasures by evaluating changes in crew performance with countermeasures in spaceflight analogs,
4) Recommend standards and guidelines appropriate for autonomous crews in LDEMs with regards to self-scheduling.
