The PDBO Algorithm for Discrete Time, Cost and Quality Trade -off in Software Projects with Expressing Quality by Defects

Abstract Software project manager's goal is getting an optimal allocation of time, cost and quality of each task/activity in the software project such that total time and cost of the project is minimized while project quality is maximized. Accordingly, mathematical and meta-heuristic algorithms have been developed in order to solve such riddle. This research paper introduces a new proposed meta-heuristic algorithm annotated as problem data based optimization (PDBO), which enjoys the fastness and achieves an optimal/near optimal solution for solving the discrete time- cost-quality trade-off problem (DTCQTP) in software projects. PDBO decides the preferred modes of performing tasks where task quality is expressed quantitatively in terms of its defects. Examples are given at the end to show the trade-off analysis between project's cost, time and quality.
