Center node: "r d analyst an interactive approach to normative decision system model construction"
  Abstract: This paper describes the architecture of R&D Analyst, a commercial intelligent decision system for evaluating corporate research and development projects and portfolios. In analyzing projects, R&D Analyst interactively guides a user in constructing an influence diagram model for an individual research project. The system's interactive approach can be clearly explained from a blackboard system perspective. The opportunistic reasoning emphasis of blackboard systems satisfies the flexibility requirements of model construction, thereby suggesting that a similar architecture would be valuable for developing normative decision systems in other domains. Current research is aimed at extending the system architecture to explicitly consider of sequential decisions involving limited temporal, financial, and physical resources.

Connected through hyperedge HE-1 (induced by source paper "normative engineering risk management systems"):
  with members:
    - "time dependent utility and action under uncertainty"
    - "decision making using probabilistic inference methods"
    - "an approximate nonmyopic computation for value of information"
