“…Under the Dynamisation theme, the Macro-Telescopic and Meso-Telescopic design concepts were shown as weak solutions for achieving time varying micromotion. The consistency ratios assessed in scoring of the design (Figure 4) and weighting of the Ideal Outcomes adhere to the recommended value of <0.1 using the AHP method, emphasising minimal inconsistency in the pairwise decision making process (Mu and Making, 2015).…”

“…The topology of the design principles are visually represented in Table 2; generated using SolidWorks 2016 (Dassault Systèmes, Vélizy-Villacoublay, France) and Netfabb 2018 (Autodesk, California, United States). Finally, the concept designs were evaluated using the AHP (Figure 4), a tool based on a set of pairwise comparisons that depend on the designers perception to evaluate and prioritise options in a multi-criteria decision making process (Mu and Making, 2015). The decision making process is hierarchically decomposed, level 1 (goal) evaluation of the design principles, level 2 (criteria), the Ideal Outcomes and level 3 (alternatives) the concept design solutions.…”

High stiffness fracture fixation devices inducing absolute stability, activate inefficient primary healing and stress shielding. Taking High Tibial Osteotomy as a representative example, review of the clinical literature and mapping the fracture healing process revealed two physically contradicting requirements, which are only partially met by current techniques. Stiffness of the fixation is required immediately after fracture, however in the remodelling phase this can cause stress shielding. Stability is required immediately after fracture, however in the ossification phase less stability is required to stimulate secondary (and more efficient) healing. This study evaluates the use of the TRIZ Inventive Design Principles to overcome these physical contradictions. Six designs concepts were evaluated, of which the Macro-Geometry stiffness modulated design was ranked the highest. This was achieved through spatial decomposition of the problem utilising the Inventive Principles of Asymmetry, Extraction and Local Quality. This study offer perspectives on how to increase the patient specificity of fixation utilising the increased topology freedom of design for additive manufacture (AM).

“…It is a multi-criteria decisionmaking technique that breaks down a complex problem into a hierarchy, in which each level is composed of specific elements [8]. The AHP methodology is used to determine the most consistent alternative with our criteria, based on the level of importance obtained for the different criteria and by considering our comparative judgements [9]. The calculation of the weighting factors of n input elements consists in comparing each pair of elements using the following scale [10]: 1The pairwise comparison of element i with element j is placed in the aij position of the pairwise comparison matrix A as shown below:…”

Research of suitability area of agriculture in Coastal CHAOUIA by integration the AHP, IDW, and MCDA to GIS

Agricultural expansion in developing countries requires a strategy to develop the agricultural sector in a sustainable and rational manner, despite its complexity to be achieved. The objective of this work is to develop an agricultural Suitability map, based on a flexible and interactive model between several methods, which are the analytical hierarchy process (AHP), the Inverse Distance Weighting (IDW), and the multi-criteria decision analysis (MCDA),integrated into the GIS. The factors selected in this study are slope, elevation, land use, minimum and maximum temperature,also rainfall for both the dry and rainy periods. The analysis of the suitability map revealed the effectiveness of this model, which allowed the detection of areas unsuitable for agricultural development. the Comparison of the suitability map with the 2019 classified map shows that agricultural expansion is highly developed and covers almost the total area, which has had negative consequences on the groundwater quality of the Coastal CHAOUIA aquifer.

“…If CR < 0.10, the matrix is consistent, otherwise if CR > 0.10 we need to re-evaluate the pairwise comparisons and test again the consistency by AHP. This procedure ensures the correct prioritization of the involved variables [58].…”

How to Define Priorities in Coastal Vulnerability Assessment

et al. 2018

Awareness of coastal landscapes vulnerability to both natural and man-made hazards induce to monitor their evolution, adaptation, resilience and to develop appropriate defence strategies. The necessity to transform the monitoring results into useful information is the motivation of the present paper. Usually, to this scope, a coastal vulnerability index is deduced, by assigning ranking values to the different parameters governing the coastal processes. The principal limitation of this procedure is the individual discretion used in ranking. Moreover, physical parameters are generally considered, omitting socio-economic factors. The aim of the present study is to complement a geographical information system (GIS) with an analytical hierarchical process (AHP), thus allowing an objective prioritization of the key parameters. Furthermore, in the present case, socio-economic parameters have been added to physical ones. Employing them jointly, an integrated coastal vulnerability index (ICVI) has been estimated and its effectiveness has been investigated. To show how it works, the proposed method has been applied to a portion of the Adriatic coastline, along the Apulian region in southern Italy. It has permitted to identify and prioritize the most vulnerable areas, revealing its efficacy as a potential tool to support coastal planning and management.
