Multi-criteria decision making for water resource management: a case study of the Gediz River Basin, Turkey

In this paper, the use of Data Envelopment Analysis (DEA) as a tool for Multiple Criteria Decision Making (MCDM) is investigated for assessing various irrigation management strategies in terms of economic, environmental and social criteria. To carry out this task, an irrigation management research project report is used for the comparison of various MCDM and DEA rankings as well as providing the required data. The DEA methods called Charnes-Cooper-Rhodes (CCR), Banker- Charnes-Cooper (BCC) and Reduced-CCR (RCCR) are employed by the integration of criteria weights through the addition of assurance regions to improve discriminating power of the analysis, and to reach the ranking of strategies. The results indicate that DEA constitutes a valuable approach to be used alternatively or in addition to MCDM, and incorporating managerial preferences into the DEA methods provide correlated results with MCDM techniques.

Objective: This study aimed to compare the outcomes of medial, lateral, posterior, and anterior approaches in pediatric Gartland type 3 supracondylar humerus fractures treated with open reduction and pinning. Methods: Gartland type 3 supracondylar humeral fractures treated by open reduction and pinning in 4 different centers with different surgical approaches were divided into 4 groups according to the surgical approach. Each trauma center applied the surgical approaches with which it had the most experience. Specifically, patients treated with medial, lateral, posterior, and anterior approaches were classified as groups 1, 2, 3, and 4, respectively. The demographic characteristics of the patients and the complications were compared. The findings were evaluated according to the Flynn criteria. Results: A total of 198 pediatric patients, 114 (57.6%) male and 84 (42.4%) female, with a mean age of 6.27 ± 2.03 (range = 1-12) years, were included in this study. They were all treated with open reduction and pinning, 51 (25.8%) by the medial approach, 49 (24.7%) by the lateral approach, 66 (33.3%) by the posterior approach, and 32 (16.2%) by the anterior approach. No significant differences in age, gender, side, or complication status were found between the groups (P > .05). There were also no significant differences between the groups regarding the Flynn cosmetic and functional criteria (P > .05). Conclusions: Superior functional and cosmetic results can be achieved with fewer complications with surgical techniques applied by experienced surgeons in the open reduction of supracondylar humeral fractures in children. It is recommended that surgeons choose the approach with which they have the most experience.
