Context: Release scheduling deals with the selection and assignment of deliverable features to a sequence of consecutive product deliveries while severalconstraints are fulfilled. Although agile software development represents a major approach to software engineering, there is no well-established conceptual definition and sound methodological support of agile release scheduling. Objective: To propose a solution, we present, (1) a conceptual model for agile scheduling, and (2) a novel multiple knapsack-based optimization model with (3) a branch-and-bound optimization algorithm for agile release scheduling.Method: To evaluate our model simulations were carried out seven real life and several generated data sets.Results: The developed algorithm strives to prevent resource overload and resource underload, and mitigates risks of delivery slippage.Conclusion: The results of the experiment suggest that this approach can provide optimized semi-automatic release schedule generations and more informed and established decisions utilizing what-if-analysis on the fly to tailor the best schedule for the specific project context.
