Abstract : In an era of declining government budgets and increasing business competition, it is critical to base investment and planning decisions on careful analysis of the cost-effectiveness of available options. Building sound and comprehensible models to support effective decision making is currently a demanding and costly process. In this Phase I SBIR Project, we have developed tools that greatly reduce the difficulty and cost of applying these methods by developing an electronic library of reusable decision modules. Specifically, we have designed, prototyped, and demonstrated the practicality of a suite of tools to: (1) use influence diagrams modules as an intuitive graphical method for creating, storing, and communicating extensible, reusable decision models; (2) create an electronic library (Decision Resources On-line) of influence diagram modules and related information and software resources accessible via the World Wide Web; (3) retrieve, adapt, and assemble these influence diagram modules to create new decision models to address new decision situations; and (4) communicate the assumptions, and key sensitivities to provide qualitative insights into model recommendations. To demonstrate these tools, we applied them to develop a prototype resource to support decision making on a variety of important public health issues, including education, screening, testing, and treatment for breast cancer, Chlamydia, measles, and tuberculosis.
