inthis article we offer a method of ranking contractors by using dea based onanalysis deficit and ahp. the process of hierarchical analysis (ahp) byproviding scales from paired comparison matrix, performs the contractor’sprioritizing choice. but ahp has some problems and to solve those problems,jahanshahloo and his colleagues presented a new model which uses dea andstandard deviation. in this a...

This paper proposes a compromise model, based on a new method, to solve the multi-objective large-scale linear programming (MOLSLP) problems with block angular structure involving fuzzy parameters. The problem involves fuzzy parameters in the objective functions and constraints. In this compromise programming method, two concepts are considered simultaneously. First of them is that the optimal ...

Traffic safety is one of the key issues nowadays, given fact that a large number people lose their lives in traffic accidents every day. There are various influential factors occurrence accidents, vehicles being them. This paper assesses Montenegro period 1998-2020 by applying multiphase modeling with purpose to obtain comparative results which enable implementation adequate strategies. A total...

The VIKOR method was developed to solve MCDM problems with conflicting and noncommensurable (different units) criteria, assuming that compromising is acceptable for conflict resolution, the decision maker wants a solution that is the closest to the ideal, and the alternatives are evaluated according to all established criteria. This method focuses on ranking and selecting from a set of alternat...

Different approaches have been explored in the past to solve fuzzy transportation or shipping problems. The cost of shipping, supply, and demand quantities are all ambiguous a dilemma. Trapezoidal numbers used represent parameters this situation. can be converted into crisp using variety ranking techniques. In paper, we've studied many techniques provided comparison two them. A numerical exampl...

The present report further investigates the multi-criteria decision making tool named Fuzzy Compromise Programming. Comparison of different fuzzy set ranking methods (required for processing fuzzy information) is performed. A complete sensitivity analysis concerning decision maker’s risk preferences was carried out for three water resources systems, and compromise solutions identified. Then, a ...

In this paper we address the problem of nding the simulated system with the best (maximum or minimum) expected performance when the number of alternatives is nite, but large enough that ranking-and-selection procedures may require too much computation to be practical. Our approach is to use the data provided by the rst stage of sampling in a ranking-and-selection procedure to screen out alterna...

INTRODUCTION The aim of this study was to explore the association between the cerebro-umbilical ratio measured at 35-37 weeks and intrapartum fetal compromise. METHODS This retrospective cross sectional study was conducted at the Mater Mothers' Hospital in Brisbane, Australia. Maternal demographics and fetal Doppler indices at 35-37 weeks gestation for 1381 women were correlated with intrapar...

The selection of offshore wind farm site (OWFS) has important strategic significance for vigorously developing new energy and is deemed as a complicated uncertain multicriteria decision-making (MCDM) process. To further promote power planning provide decision support, this paper proposes hybrid picture fuzzy (PF) combined compromise solution (CoCoSo) technique prioritization OWFSs. begin with, ...
