Sharing research models: Using software engineering practices for facilitation


Bryant, S., Solano Mora, E., Cantor, S., Cooley, P., & Wagener, D. (2011). Sharing research models: Using software engineering practices for facilitation. (RTI Press Publication No. MR-0022-1103). Research Triangle Park, NC: RTI Press. DOI: 10.3768/rtipress.2011.mr.0022.1103


Increasingly, researchers are turning to computational models to understand the interplay of important variables on systems' behaviors. Although researchers may develop models that meet the needs of their investigation, application limitations—such as nonintuitive user interface features and data input specifications—may limit the sharing of these tools with other research groups. By removing these barriers, other research groups that perform related work can leverage these work products to expedite their own investigations. The use of software engineering practices can enable managed application production and shared research artifacts among multiple research groups by promoting consistent models, reducing redundant effort, encouraging rigorous peer review, and facilitating research collaborations that are supported by a common toolset. This report discusses three established software engineering practices—the iterative software development process, object-oriented methodology, and unified modeling language—and the applicability of these practices to computational model development. Our efforts to modify the MIDAS TranStat application to make it more user-friendly are presented as an example of how computational models that are based on research and developed using software engineering practices can benefit a broader audience of researchers.
