PPSP_simheuristic_Montecarlo_with_GA_Optimization

This code corresponds to a simheuristic approach to the Project Portfolio Selection Problem. The risk register, the schedule network (analyzed via critical path method) and baseline cost and stochastic cash flows are simulated to obtain a project reliability curve. Project reliabilities are aggregated, considering also correlations to evaluate the portfolio reliability. Portfolio reliability becomes as a constraint, so that promising portfolios are extracted that maximize returns within a specified reliability level. This code uses a realistic instance of 20 projects, and features an experiment to validate the algorithm and evaluate its performance It also includes a realistic instance generator, for other researchers that may be interested in further testing of alternate algorithms For a more detailed explanation, you can read our related paper in the Journal xxxxxx.
