Optimization of scheduling the use of vats during the wine fermentation process

Sammanfattning: In this paper the goal was to optimize the scheduling of vats for the wine fermentation process considering demand, time and quality constraints in order to minimise the production cost. The method that was used during the project was to start of with a simple model that only took the basic parameters in to account, verify that it worked, and then add up parameters until the model was completed. An integer program was formed to obtain the optimal solution to the problem och to test the programs accuracy a small example that could be tested by hand was made. It showed that the program worked as expected and a conclusion that was drawn was therefore that the program would work for larger problems, that are more based in reality, as well. After testing the program for larger problems another conclusion that was drawn was that for instance a larger vintage period and an increased frequency of supply led to an increase in the solving time.
