Multi-criterion objective function in the net floating processes

The method consisting in the application of the floating theory in the nets for designing production processes in agriculture together with the multi-criterion objective function has been presented in this paper. Practical application of the method includes estimation of a variable for each component. Application of the objective function means establishing a set of solutions that are equivalent from the point of view of a single criterion. The subsequent procedure is based on the application of the next function chosen for such an equivalent set of solutions obtained. Calculations are made until all the components of the multi-dimensional objective function have been used. Then, the process is repeated changing the initial criterion of choice. The problem becomes a typical combinatory issue where each possible interdependence variant of a particular one-dimensional criteria should be analysed. The criteria of choice considered can be the following: cost, labour or energy inputs reduction. The example of method application are shown.
