Landfill Allocation Process

Criteria WEIGHTING

Setting Exclusion Criteria(I)

I. Exclusion Criteria

• These exclusion criteria are minimum distance limits from specific land uses and places of interest

• Potential landfill sites should comply with all the exclusion criteria in order to proceed to the multi-criteria analysis otherwise they are excluded

• The software provides a list of 15 exclusion criteria but the user can add or remove one or more criteria

The limit distance below which the examined area is excluded

Criterion ID from X1 – X15

Exclusion criteria are distances from specific land use or place of interest

areas that comply with the criteria

Setting the criterion ID e.g. X16, X17… X20 etc

WEIGHTING the Criteria


II. Multi-criteria Analysis• 5 Group criteria with the corresponding sub-criteria (48 in total)

• Weighting of Group and sub-criteria - determining the importance of each group and each sub-criterion (through the use of questionaire to ++) Weighting factors are the same for all examined areas.

• The evaluation of the examined areas is based on a 1 to 10 scale (10 being the maximum value) of the predetermined sub-criteria

• Calculation of the Q/P/W values

Group Criteria (5) Sub-criteria (48)

Hydrogeological criteria (Group A) 15 sub-criteria A1 to A15

Land - Planning criteria (Group B) 16 sub-criteria B1 to B16

Environmental criteria (Group C) 4 sub-criteria C1 to C4

Operational-General criteria (Group D) 9 sub-criteria D1 to D9

Financial- Economic criteria (Group E) 5 sub-criteria E1 to E5

SETTING and WEIGHTING of Criteria


Multi-criteria Matrix of all criteria (Groups A, B, C, D & E)

Evaluation of the examined areas - 1 to 10 scale for each subcriterion

Multi-criteria Matrix

W(ij)= [%weight of Group criterion (i) * weight of Sub-criterion(ij)]/10000

P(A4) = 3 * Q(A4) = 3 * 0,7 = 2,1

Q(A4) = {max[subcriterion (A4)] – min[subcriterion (A4)] }/10, = (10 – 3)/10 = 0,7

Q/P/W values

Example of W(A4) calculation

Weight of Group A criterion = 30%

Weight of Sub-criterion A4 = 5%

W(A4)= { 30%* 5% } / 10000=0.015
