[The use of operation research tools as a way of more effective utilization of the resources of health service institutions].

In all aspects of human life including medical we can find planning, organizing and controlling of activity. We aim at the proper goal supported by our resources and knowledge. Often we cannot make a decision freely because of surrounding circumstances: economic, organizational, political and others. Taking into account our goals some decisions are good, others are bad. The problem is how to make the best decision. Nowadays, statistical and mathematical tests are widely used in economy. One of the sciences concerned with in evaluating managers' decisions is operations research. Summing up, operations research deals with the problem of how to gain means and use resources in the most effective way taking into account surrounding limitations. As an example of a place where one of the operations research tools (linear programming) is used as a way of work optimalization is Medical Rehabilitation Unit in John Paul II Hospital in Zamość. It is a method in which goal function (that is criterion of optimalization) and limitations are linear functions. The problem is to find a solution (regarding limitations) so that the goal function has the greatest value. The aim of the study is to present and encourage managers to use linear programming as a way of improving effectiveness and disclosing weak points of organization.
