“…The analytic hierarchy process (AHP) was developed by Saaty () in the late 1970s and was originally applied to the marketing sector (Schmidt, Aumann, Hollander, Damm, & Schulenburg, ). It was based on three principles: decomposition, measurement and synthesis (Scala, Rajgopal, Vargas, & Needy, ). According to the evaluation of the index results and importance of the consulting experts, this research established the judgement matrix using yaahp7.5 software with the AHP to determine the weight coefficient of each index.…”

Aim and objective To establish an index system for the evaluation of undergraduate nursing student innovation ability. Background An index system for evaluation of undergraduate nursing student innovation ability has not been established. Design A three‐round Delphi survey sought opinions from experts about the index system for evaluation of undergraduate nursing student innovation ability. Methods A Delphi survey was used for the study of 19 experts from nursing education, clinical nursing and health management. The consistency of consultation results formed the basis for determining the rounds of consultation. With the importance of consulting experts in the last round, we established the judgement matrix using yaahp7.5 software and the analytic hierarchy process and determined the weight coefficient of each index. A modified recommendation for the Conducting and Reporting of Delphi studies (CREDES) was used to guide this study. Results Nineteen experts from 10 nursing colleges and nine third‐level first‐class hospitals in seven domestic provinces/municipalities were included in this study. The index system was divided into primary, secondary and tertiary levels. Consensus was reached on three primary indicators (‘spirit’, ‘ability’ and ‘achievement’), nine secondary indicators and 28 tertiary indicators. Conclusions A unified and hierarchical quality assessment index framework for nursing undergraduate creative ability was established. The framework should be further tested and improved in practice. Relevance to clinical practice Nursing students are the main force behind clinical nursing in the future. An innovative approach to skill acquisition and application could enhance the student nurse experience. The innovative ability of nursing students is important for identification of education strategies that be implemented to better support those individuals. Furthermore, the construction of the index system is helpful for evaluation of the innovation ability of nursing students that are required to better meet the needs of clinical nursing work in the future.

“…Such as any other levels, pairwise comparisons have to be made by filling a PCM that is constituted by the evaluator groups (note that the evaluators of this phase can be different persons than the ones in the original survey). The procedure of deriving weights is also identical with any other criteria see Formula (4), evidently after the consistency check (5) and (6). Due to the nature of the eigenvector method, the results of (4) are normalized to the value of one, and thus, the overall scores and ranking of the decision elements can be gained by simply multiplying the weight scores of significance attained to each decision maker group with the preference weight scores (related to criteria and sub-criteria of the decision) of that certain group.…”

Sustainable Urban Transport Development with Stakeholder Participation, an AHP-Kendall Model: A Case Study for Mersin

Public transport development decisions are generally made by local government representatives or managers of the local transport company through a top-down procedure. However, if the implications do not meet the demand of the public, the improvement cannot be considered as sustainable and in a long range, correction is necessary. This paper aims to introduce a new model which is capable of supporting public transport development decision making by examining the preferences of different stakeholder groups (passengers, potential passengers, and local government) and creating an acceptable coordination for an ultimate, sustainable decision. In the model, Analytic Hierarchy Process is applied, combined with Kendall rank correlation and an extra level of stakeholder significance in the decision. A case study is also presented on the situation of a Turkish city: Mersin. The results show, that by the application of the new model, a more integrated and thus more sustainable solution can be created for the public transport problems of the city, and by this, probably more citizens can be attracted to use public transport modes which might result in decreased CO2 emissions.

“…Saaty and Vargas () have shown in their work that GMM cannot be applied in scenarios where decision makers are unable to achieve consensus, and there are significant dispersed judgements (i.e., nonhomogeneity of group judgements). Building on this inadequacy of GMM, Scala, Rajgopal, Vargas, and Needy () developed an approach referred to as the principal components analysis (PCA) to account for judgement dispersions and when decision makers are not keen and/or unavailable to revise their previous judgements. PCA regard the decision makers as variables for each paired comparison and derive their weights from the first principal components (i.e., eigenvectors from the covariance of the comparison matrices defined as logarithm matrices) for the aggregation of their judgements with the weighted geometric mean.…”

To select appropriate fire protection options for buildings during their design stage, economic, safety, environmental, and societal criteria need to be accounted for. The divergent and sometimes conflictual desires from different fire design stakeholders involved in the process present a multicriteria decision problem. Design decision criteria and fire protection options can be interdependent, and so there is a need to manage these desires with an advanced decision analysis technique, thereby reducing uncertainties in the complex decision-making process.The aim of this paper is to use the weighted/geometric mean method-analytic network process (W/GMM-ANP) to balance the opinions of fire design stakeholders extracted from 42 structured stakeholder interviews on selecting the most suitable fire protection option for buildings constructed of steel frames. Different categories of interdependent decision elements were developed from 22 design decision criteria and 5 proposed fire protection options to produce a network of decision clusters for multicriteria decision analysis. In the synthesis and ranking of fire protection options, the W/GMM-ANP accounted for the multiple interdependencies of weighted and unweighted stakeholder desires and managed the complexity of the decision-making problem. The technique is proposed for approaching suitable group decisions in structural fire design of steel-framed buildings as well as other performance-based engineering decision making that may involve multidisciplinary stakeholders. KEYWORDSfire protection options, group decision making, multicriteria decision analysis, stakeholder views, steel-framed buildings, weighted/geometric mean method-analytic network process (W/GMM-ANP) | INTRODUCTIONFire safety is one of the fundamental necessities in the design and construction of buildings and other infrastructural facilities, with the aim to reduce to an acceptable risk level the loss of life, property, and environmental damage (Buchanan, 2001).This entails the determination of the fire risk levels (i.e., likelihood and impact of fire) at the initial design stage before deciding the means of achieving safety. Modern facets of fire safety in buildings include preventing fire ignition through fire risk management, fire detection and provision of warning to building occupants, provision of adequate escape routes, fire growth and spread management, enhancing firefighting operations, and averting building collapse (Yung, 2008). In cases of controllable or slowly growing fires, these fire safety goals can be achieved through timely detection and suppression with automatic sprinklers. However, during a severe or fast growing fire, the control of fire spread, protection of adjacent buildings, and prevention of building collapse will necessitate fire resistance of structures and fire barriers (Buchanan, 2001). In this case, the fire is resisted with passive protection measures, which are systems that are built into the structure and fabric of buildings.Building designs for fire safety...
