Evaluation of land parcels with drainage systems for its renovation

Hydraulics and Engineering Hydrology

Calculation of complex evaluation of land drainage plots (ME criteria) is carried out on the base of Saaty pairwise comparison method. In the case this method involves pairwise comparisons of 4 criteria (TC, EC, SC and ECC) to create a ratio matrix. It takes as an input the pairwise comparisons and procedures the relative weights as output. Specifically, the weights are determined by normalizing the eigenvector associated with the maximum eigenvalue of the ratio matrix. Complex evaluation of land drainage plots is carried out for two special cases:

1) in case of ecological criterion is more important;
2) in case of economical criterion is more important.

The use of method of multi-criteria assessment for definition the index of multiple evaluations allows creating integrated description of current state of the drainage areas.
