These models/procedures will be capable of helping users solve <br />problems identified through the problem~entered design/cognitive walk-through procedure. <br />In addition, a number of characteristics of the models/procedures will be known. An <br />imponant result of this task will be the identification of model integration issues, such as <br />spatial and temporal aggregation and disaggregation requirements. <br /> <br />There will be two final products of this task. The first will be a matrix that will show <br />the relationships among the problems (i.e. the decisions to be made) and the models that <br />support that decision-making process. A second matrix that will show the characteristics of <br />each model (i. e. one dimension will be a list of the models; the other dimension will be a list <br />of model characteristics and will be filled in with descriptive information). Competing <br />models will be rated according to a scale to be developed during the feasibility study. <br />Finally, a recommendation will be made on the models to be incorporated in CRDSS. <br /> <br />TASK 3: DEFlNlTION OF DATA REQUlREJ.'Vffi'ITS <br /> <br />As many of the other tasks presertted here, this task will strongly depend on the <br />problem descriptions and outcomes derived from the problem-centered design effort. <br />Although data requirements for models are often well defined, the problem-centered design <br />endeavor will help to derine the nature of the information required by users of the CRDSS. <br />This may well involve the transformation of data into other forms of information. <br /> <br />An important issue concerns the relationship between available data, the use of models <br />and the conceptual design of the system. Although some of this is detailed on in Task 5, <br />data-centered approaches to system design have available/required data at their center, with <br />the models in the integrated system "adapted" to those data requirements. For that type of <br />a system. a problem-centered design is most attractive since it allows the specification of <br />required data as a need by itself, rather than being the necessary effect of choosing one or <br />more specific models. <br /> <br />Administr:ltion <br /> <br />. <br /> <br />This taSk will be led by David Sieh with input from Hussam Fahny, Steve Wehrend <br />and Anand Prakash. <br /> <br />- <br />-,- <br />
