Underground mining method selection is one of the most crucial decisions that should be made by mining engineers. Choosing a suitable underground mining method to carry out extraction from a mineral deposit is very important in terms of the economics, safety and the productivity of mining operations. The aim of this study is developing a fuzzy model to selection the optimum mining method by usi...

this study investigated the effects of rehabilitation of sidewalks on improvement of the pedestrians’ mobility. in order to successfully achieve this, sidewalk characteristics were determined via previous studies, expert elicitation and field studies and seven parameters which are available in tehran’s sidewalks were chosen. these seven parameters were “side trees of sidewalks”, “width of sidew...

In this paper, we use experimental economics methods to test how well Analytic Hierarchy Process (AHP) fares as a choice support system in a real decision problem. AHP provides a ranking that we statistically compare with three additional rankings given by the subjects in the experiment: one at the beginning, one after providing AHP with the necessary pair-wise comparisons and one after learnin...

The ahp genes encoding the two proteins (F52a and C22) that make up an alkyl hydroperoxide reductase were mapped and cloned from Salmonella typhimurium and Escherichia coli. Two classes of oxidant-resistant ahp mutants which overexpress the two proteins were isolated. ahp-1 was isolated in a wild-type background and is dependent on oxyR, a positive regulator of defenses against oxidative stress...

OBJECTIVE The standard obstetric ultrasound examination includes documentation of arms and legs. The purpose of this study is to review the efficacy of ultrasound for the detection of limb anomalies, the type and incidence of associated malformations and pregnancy outcomes. METHOD All cases of polydactyly (POD), abnormal hand position (AHP), limb reduction defects (LRD) and arthrogryposis (AR...

In the agile virtual enterprise forming process, with the increase of optional scheme, to use the traditional analytic hierarchy process (AHP) to choose ally will produce judgment matrix inconsistency problem. Therefore, combining the AHP and the fuzzy theory, a new ally selection method which is based on web is proposed. The proposed method uses the AHP to calculate the weight of the evaluatin...

A fuzzy decision analysis method for integrating ecological indicators was developed. This was a combination of a fuzzy ranking method and the analytic hierarchy process (AHP). The method was capable of ranking ecosystems in terms of environmental conditions and suggesting cumulative impacts across a large region. Using data on land cover, population, roads, streams, air pollution, and topograp...

The analytic hierarchy process (AHP) is a structured technique for dealing with complex decisionmaking and is already used to solve many group decision problems. This paper used the CauchySchwarz inequality to improve the AHP algorithm that was developed by Escobar et al. (2004). They provided an upper bound for the group geometric consistency index in order to prove that the group geometric co...

This study was carried out to evaluate the capability of a combined fuzzy-analytic hierarchy process (AHP) method for soil fertility evaluation of common bean in Shiraz, Iran. A set of membership functions was constructed to represent the soil fertility classes, which were derived from 50 field samples collected through a purposive sampling approach. Seven soil parameters including phosphorus (...

In stereotype-based recommendation systems, user profiles are represented as an affinity vector of stereotypes. Upon the registration of new users, the system needs to assign the new users to existing stereotypes. The AHP (Analytic Hierarchy Process) methodology can be used for initial elicitation of user preferences. However, using the AHP procedure as-is will require the user to respond to a ...
