For a problem, which was described in such a way, it was possible to solve the
real task. The problem included around 200 machines and 750 half-finished and finished
products. In order to solve the problem, the library of the operational research
program CoinMP was used. The library, which was run on the computer equipped
with Intel Core2 Duo 2GHz processor and computer systemWin XP, can provide the
solution in the time of around 1s. The use of the simple operational research system
lp solve which was responsible for providing a solution to a previous task, in this instance
did not guarantee a solution, even in the time of 30 minutes. From the factual
point of view the high precision of obtained solutions was confirmed by planners.
Whereas the value of the indicator OEE (overall equipment effectiveness), which is
used to measure the effectiveness of equipment, was raised from the level of 20%,
which was achieved before the implementation of presented model, to the level of
38% after its implementation. At present, the system has worked in the company for
over half a year and is used after every change of production plan in the planning
period. The time needed for finding the solution is usually 2 seconds.
