This paper describes a linguistic text mining tool for analyzing problem reports in aerospace engineering and safety organizations. The semantic trend analysis tool (STAT) helps analysts find and review recurrences, similarities and trends in problem reports. The tool is being used to analyze engineering discrepancy reports at NASA Johnson Space Center. The tool has been augmented with a statistical...
A storyboard tool has been prototyped that supports authoring, evaluating, and exporting a concept of operations and its illustrations. A requirements engineering prototype has uncovered new requirements to communicate the intended use of the storyboard tool. New designs include an elaborated help system, vertical linking of related information, and a work plan guide. The elaborated help system informs...
We describe progress in developing a software tool to help create, communicate, and refine concept of operations (ConOps) information. Information found in a ConOps document is central to our tool. ConOps documents are written in the end user's language, describing how the proposed system should support the users' tasks. While there are some helpful documents prescribing ConOps format, there is little...
We describe an approach and existing software tool support for effective interactions between human factors engineers and systems engineers in early analysis activities during system acquisition. We examine the tasks performed during this stage, emphasizing those tasks where system engineers and human engineers interact. The concept of operations (ConOps) document is an important product during this...
Concepts and prototypes are discussed for data-based logger (D-Logger) to meet coordination challenges arising from new exploration mission concepts. The challenges include increased crew autonomy, multiple concurrent missions, reduced-size flight support teams with multidisciplinary flight controllers, and migrating some flight support activities to offices. A spiral development approach has been...
