A cost estimation model for OEM based military software support

Military software supportability increasingly becomes a key factor of equipment system supportability, and the proportion of software support cost in the system is rising significantly. Based on the analysis of the processes of supportability design and implementation, the paper proposes several effective methods for estimating software costs in the different stages and aspects, and constructs a general-purpose cost estimation model for military software support. Case studies on real-world projects demonstrate the feasibility and rationality of the model.
