“…One widely used MCDM technique is the AHP, which reduces complex decisions to a series of pairwise comparisons [65]. The first step in an AHP analysis is to build a hierarchy for the decision, based on the goal, criteria, and alternatives [66] ( Figure 6). In the next step, a pairwise comparison matrix of the criteria involved in the decision needs to be created, to derive the relative priorities (weights) for the criteria.…”

Check dams are widely used watershed management measures for reducing flood peak discharge and sediment transport, and increasing lag time and groundwater recharge throughout the world. However, identifying the best suitable sites for check dams within the stream networks of various watersheds remains challenging. This study aimed to develop an open-source software with user-friendly interface for screening the stream network possibilities and identifying and guiding the selection of suitable sites for check dams within watersheds. In this developed site selection software (SSS), multi-criteria decision analysis (MCDA) was integrated into geographic information systems (GIS), which allowed for numerous spatial data of the multiple criteria to be relatively simply and visually processed. Different geomorphometric and topo-hydrological factors were considered and accounted for to enhance the SSS identification of the best locations for check dams. The factors included topographic wetness index (TWI), terrain ruggedness index (TRI), topographic position index (TPI), sediment transport index (STI), stream power index (SPI), slope, drainage density (DD), and stream order (SO). The site identification performance of the SSS was assessed using the receiver operating characteristic (ROC) curve method, with results for the case study example of the Poldokhtar watershed in Iran showing excellent performance and identifying 327 potential sites for efficient check dam construction in this watershed. The SSS tool is not site-specific but is rather general, adaptive, and comprehensive, such that it can and should be further applied and tested across different watersheds and parts of the world.

“…In this step, the intensity of the values used in the method was found to be derived from the subjective preferences of the researchers, which may result in inconsistencies in the final matrix. Therefore, to define the acceptable value for this inconsistency, the AHP calculates a consistency ratio (CR) by comparing the consistency index (CI) of the matrix in question to a random consistency index, or RI [37]. The RI is presented in Table 3.…”

This study proposed a method for identifying areas appropriate for fish farming in ground-excavated ponds using data obtained from public institutions. The method was applied to three cities located in the central-southern region of Paraná State, Brazil. In order to select appropriate areas, a geographic information system (GIS) was created using data from a digital elevation model (DEM), as well as data on soil occupation and type. A variable reclassification model (VRM) was created, and the analytic hierarchy process (AHP) method was applied to establish weights for a multi-criteria assessment of the factors. Non-classifiable areas and areas with constraints were identified and removed from the analysis. The sites classified as highly suitable or suitable represented 33.270.79 ha (18.71% of the total area), while the restricted areas represented 54,427.91 ha (30.60% of the total area). This method may represent a useful tool for decision making in the context of regional planning and may be used in the establishment of public policy and in the allocation of resources for aquaculture development.

“…The random matrix consistency index (RI) for a 6 × 6 matrix is 1.25. Also, the CI and CR was found to be 0.004 and 0.0032 which were lower than 0.1, indicating that our proportion of subjective weights was reasonably consistent and reliable (Mu & Pereyra‐Rojas, ; Saaty, ).…”

The aim of this study is to evaluate several weaving knife configurations in response to multiple criteria's for optimum design. Nine different knife combinations were tested over ten female weavers in a field experiment. Three levels of blade width and angular orientations were taken as the independent variables. Output response about goniometry and electromyography were taken as dependent variables. Multivariate analysis was carried out to estimate the effect of independent variables on output responses. To tackle the difficulty of knife selection with several output responses, three multicriteria optimization approaches have been compared. Multivariate analysis of variance results showed that the effect of both blade width and angle were significant at wrist angles. Also, the magnitude of effect size on both blade width and the angle was highest for the wrist angles. Despite the same weighing criteria, a slight difference was evident between the ranks from optimization methods. The higher blade widths and smaller angular orientations should be recommended for reduction of wrist deviation and muscle activity during weaving. The best possible combination of knife evaluated using multicriteria optimization was 25 mm × 100°.
