Abstract: In this paper an economic productivity model for software corrective maintenance process is presented. The productivity is analytically modelled using economic value of the maintenance process as the output, and the pre-committed fixed cost and variable cost as input. The Analytical Theory of Project Investment is used to model the relationship of the economic value and these cost components. The values of corrective software maintenance process are analysed. A simulation approach is investigated to analyse the influences to the productivity in software corrective maintenance. This simulation approach provided a tool to identify and analyse the optimal parameters in productivity using the economic model.

Keywords: economic models; simulation; software maintenance; corrective maintenance; influence factor; economic value; economic productivity; modelling.
