This proposal addresses the prototype development of a decision aid development support environment (dadse) that incorporates the usage of both the ada and lips programming languages. The prototype will provide a development environment for the decision-aid programmer and researcher to investigate the full requirements for a productionlevel dadse. The prototype dadse will provide the ability to use either a single language, ada, to develop simple decision-aid applications or provide the option to the developer to utilize both ada and lips for more sophisticated requirements. The phase ii work will also include investigations of the use of the prototype on selected decision-aid applications. This will help provide metrics for the measurment of the adequacy of the dadse as a viable product in the development of dod decision-aid applications.
