Selecting a Contractor by Using a Novel Method for Multiple Attribute Analysis: Weighted Aggregated Sum Product Assessment with Grey Values (WASPAS-G)

Selecting the right contractor in construction industry is an important problem for an organization while the competition in global markets increases. Evaluating contractors’ performance is a multiple attribute decision making process consisting of vagueness and imprecision. It is based on a set of hardly exact measurable attributes: capability and skills, occupational health and safety, techni...

A Novel Method for Multiple Criteria Analysis: Grey Additive Ratio Assessment (ARAS-G) Method

The paper presents the process of the selection of a potential supplier, which have to be the most appropriate to stakeholders. The selection is based on a set of criteria: Delivery Price, Financial Position, Production Specifications, Standards and Relevant Certificates, Commercial Strength, and the Performance of supplier, etc. The criteria for evaluation and their importance are selected by ...

Selecting the Best Waste Disposal Method in Health Using Combined Method of Fuzzy Analytical Hierarchy Process and Fuzzy Weighted Aggregated Sum Product Assessment

Background and Aim: Inattention of hospital waste management has caused many problems. As a consequence, it has put the environment and human health at serious risk. Medical centers are one of the important health institutions which in recent years, population growth, increasing clients and service populations has led to significant growth in waste production in them.

Free Vibration Analysis of Quintic Nonlinear Beams using Equivalent Linearization Method with a Weighted Averaging

In this paper, the equivalent linearization method with a weighted averaging proposed by Anh (2015) is applied to analyze the transverse vibration of quintic nonlinear Euler-Bernoulli beams subjected to axial loads. The proposed method does not require small parameter in the equation which is difficult to be found for nonlinear problems. The approximate solutions are harmonic oscillations, whic...
