Fuzzy Analytic Hierarchy Process for Risk Assessment to General-assembling of Satellite

Abstract

With a fuzzy analytic hierarchy process, the hierarchy of risk factors in satellite general-assembling process is established, based on which, the weights of various risk factors are determined one by one. Furthermore, the risk factors are quantitatively analyzed, and the comprehensive risk assessment model is established in the end. Taking a satellite model as an example, the risks in the satellite general-assembling process are assessed comprehensively, and the risk levels are quantitatively measured. The factors are sorted according to their impact capabilities to the overall risk level, and the key points of risk control for satellite general-assembling process is clarified. Results obtained from the analysis to risk sub-factors suggested that experience and techniques, narrow space and production rhythm are more detrimental to process risk than any other sub-factors. The results also show that the risk could be mitigated, provided that the effectiveness of engineering measures against deficiencies in the most influential (sub-)factors is maintained. The rationality and feasibility of the proposed method model is proved by the engineering application, which provide the effective technical support for the risk control in satellite general-assembling process.

Evaluation of important buildings anti-terrorism capability based on fuzzy analytic hierarchy process

“…However, AHP involves human subjectivity, which introduces vagueness and uncertainty. There has been plenty of research that blends fuzzy logic, which is a popular method of incorporating uncertain attributes into the decision-making process, with AHP to form a model for risk assessment [10]. These risk evaluation models are widely applied to multiple fields such as modular product designs [11], information technology projects [12], power transformers [13], and behavior-based safety management [14].…”

Design of Decision Support System for Road Freight Transportation Routing Using Multilayer Zero One Goal Programming

“…Chang [42] presented an extent analysis method which was a new approach in pairwise comparisons of FAHP with triangular fuzzy numbers. This approach has been used extensively in many different fields, more researches can be found in [34,36,37,[43][44][45][46][47][48]. This approach was used in this study because it is easy, simple, similar to the traditional AHP, and contemplative to the value of fuzzy synthetic extent and degree of possibility for rational relative weights.…”

Priorización de Riesgos Operacionales para un Proveedor de Tercera Parte Logística - 3PL

“…Para la aplicación del AHP difuso se definieron los criterios considerados más importantes por los expertos de la organización. Posteriormente dichos criterios fueron ponderados utilizando la escala difusa presentada por (Tian y Yan, 2013) y mediante la aplicación de las comparaciones pareadas del método AHP se obtuvieron los resultados que se muestran en la tabla 4. Es de destacar, que la priorización se hizo de manera independiente para los riesgos en transporte y los riesgos en almacenamiento, y que los principales riesgos de acuerdo con esta metodología coinciden con los definidos como críticos en la matriz de la Fig.…”
