5.5. External IAAM Analysis Not all analytical work is performed integral to the model In fact, a great deal of analytical work must be performed external to the model, in order to generate input parameters and parametric relationships which can be used with confidence. Prior to running the integrated model, external analyses are required for each of the architecture elements, in order to generate input parameters and parametric relationships which can be used with confidence. An example of the interaction of the IAAM with external analyses for economic inputs, as well as external analyses for orbital coverage for a selected constellation, is shown in Figure 5-19. The economic analyses required include a specific representation of the supply and demand characteristics of each target market to be served: market size, projected growth, and price points for demand, including an assessment of demand elasticity with respect to price. Other cost information for external ■igure 5-19 IAAM Requires Input from External Analysis factors may also be required. This analysis yields a profile of revenue potential for each target market. Preliminary technical analysis includes the design architectural configuration itself The preliminary analysis must address all questions of technical feasibility of the design, since the IAAM model assumes that each candidate architecture will deliver the claimed performance levels. For example, adequate ground site coverage by the orbiting element(s) must be assured by work completed external to the IAAM model The exact number of power collector and power relay satellites are inputs to the model 5.6. Model Input Data Requirements The data required for input into IAAM include over 200 parameters. These parameters address performance and cost characteristics of the various architecture elements, which depend on the specific architecture under investigation. A summary of the parameters required for input in the form found in the model is shown on the following tables 1-6. The information presented in the input sheet includes the range of data for each parameter, to address uncertainty, should an uncertainty-based analysis be desired. This can be accomplished by setting the uncertainty analysis button to the “on” setting. In addition, the source of the data for each parameter is indicated in the summary input sheet. It is stated in a column to the right of the values, as well as being color-coded for the values such that their source can be correlated to their color.
