Cost Estimation Techniques for C3I System Software.
Abstract
This research developed the concept and computer programming requirements for a software life cycle cost estimating system which included methodology for the establishment of a database for Command, Control, Communications and Intelligence (C3I) system sizing. The proposed system uses the cost estimating relationships of the constructive cost model (COCOMO) model and generic files of baseline C3I software designs for aid in sizing the number of source instructions required for a new design. The computer programming requirements are developed for a user-friendly interactive program. They permit computer program configuration items to be designed by choosing computer program components (CPCs) from a stored library of functionally structured computer program modules. They permit CPCs to be designed by choosing generic modules of code from a similar stored library. They permit iterative life cycle cost estimates to be made at each level of the software breakdown structure with automatic re-computation with input changes. Originator-supplied key words: parametric models, embedding, regression analysis, interactions, libraries. (Author)
