OptaPlanner (formerly Drools Planner) is a planning engine for optimization of business resource usage. One of the most important features of OptaPlanner is the benchmarker, used to compare how different configurations perform on a specific problem. Currently, the results of individual benchmark runs are not persisted, therefore their processing is limited only to the scope of a single application run. This is particularly problematic when the process terminates unexpectedly as it leads to the loss of results. The main goals of the thesis are:

• to examine abilities and usages of the OptaPlanner engine and provide a brief overview of the configuration options;
• to implement improvements of the Benchmarker in order to mitigate the problem of long-running task abrupt termination;
• to provide mechanism that would allow comparison of results over different Benchmarker runs.
