Occurrence of human error in highly complex systems, such as a cockpit, can be disastrous and/or overwhelmingly costly. Mismanagement of multiple concurrent tasks has been observed by researchers to be a type of repetitive human error in previous studies of accidents and incidents. This error may occur in the form...
Concurrent Task Management (CTM) can be defined as the process that human operators of complex systems perform to allocate their attention among multiple, simultaneous tasks. A challenge of CTM research is to create an experimental environment which is complex enough to model a real world multitasking situation. Also, this system...
Concurrent Task Management (CTM) is the process by which human operators of complex systems (such as pilots, drivers, surgeons, and operators) allocate their attention among multiple concurrent tasks (Funk, 1991). A more thorough understanding of the human operator's knowledge, skills, and
abilities associated with CTM might help us to prevent...
Task prioritization performance was evaluated for pilots who participated in a concurrent task management (CTM) training course and pilots who did not. CTM is the process by which pilots selectively attend to high priority tasks and shed non-priority tasks. Twenty seven pilots enrolled in a university flight technology program were...
Funk’s (1991) cockpit task management (CTM) theory is structurally consistent with cognitive multitasking models: it addresses managing multiple and concurrent tasks in three stages: situation awareness, response selection, and response execution. Based on CTM theory, Colvin, Funk and Braune (2005) hypothesized that the following six factors may affect task prioritization:...
The research presented in this dissertation addresses the Multi-Mode Resource-Constrained Project Scheduling Problem (MMRCPSP) in the presence of resource unavailability. This research is motivated by the scheduling of engineering design tasks in automotive product development to minimize the project completion time, but addresses a general scheduling situation that is applicable...
Research in the aviation domain, driving distractions, anesthesia
administration, and nuclear power plant control rooms show that Concurrent Task
Management (CTM) is a process that every human operator performs when
interacting with complex environments. The need for understanding concurrent task
management in a broader perspective more applicable and generalizable to...
Task-set inhibition has been proposed to be an important mechanism for cognitive control in task switching. Its existence is supported largely by the observation of the N-2 repetition cost (e.g., A-B-A is slower than C-B-A). Many studies have reported an N-2 repetition cost, but several have not. Because of the...
