Human Performance of Novice Schedulers for Complex Spaceflight Operations Timelines  (2021)
Abstract Header
Objective: Investigate the effects of scheduling task complexity on human performance for novice schedulers creating spaceflight timelines.
Background: Future astronauts will be expected to self schedule, yet will not be experts in creating timelines that meet the complex constraints inherent to spaceflight operations.

Method: Conducted a within-subjects experiment to evaluate scheduling task performance in terms of scheduling efficiency, effectiveness, workload, and situation awareness while manipulating scheduling task complexity according to the number of constraints and type of constraints.

Results: Each participant (n = 15) completed a set of scheduling problems. Results showed main effects of the number of constraints and type of constraint on efficiency, effectiveness, and workload. Significant interactions were observed in situation awareness and workload for certain types of constraints. Results also suggest that a lower number of constraints may be manageable by novice schedulers when compared to scheduling activities without constraints.

Conclusion: Results suggest that novice schedulers' performance decreases with a high number of constraints, and future scheduling aids may need to target a specific type of constraint.

Application: Knowledge on the effect of scheduling task complexity will help design scheduling systems that will enable self-scheduling for future astronauts. It will also inform other domains that conduct complex scheduling, such as nursing and manufacturing.
