A Solution Approach for Agricultural Service Center Location Problem Using TOPSIS, DEA and SAW Techniques - Technology Management for Sustainable Production and Logistics - page 35

Fig. 5 The summary of developed MADM approach

There are two type of attributes viewpoint of their preferred values, i.e. there are
two optimization directions: lower values of are preferred for some attributes,
e.g. distances, while higher values is outrank for the ASCLP to select such candi-
date location for establishing ASC on it, e.g. the total cultivated area. To address
two separate formulations for maxi-min and maxi-max attributes are defined
(see Eqs. 16 and 17 ). These equations will be used to compute the suitability of
candidate locations for service center establishment.
