Multi-criteria analysis for the impact assessment of food safety policies: The case of EU regulation on dietary arsenic
Provedor de dados: 31
Autores: Ragona,   Maddalena; Mazzocchi,   Mario; Alldrick,   A.J.
Developments in knowledge concerning the toxicology and occurrence of dietary arsenic suggest that levels of exposure in some groups of the population within the EU are a cause for concern. This applies also in the case of individual Member States where local regulatory limits exist. The situation is such that some foods on the market are already the subject of consumer advice provided by government agencies. In the light of these considerations, some have suggested that Member States’ legislation concerning arsenic in foods should be modified and harmonised to reflect such developments. An evaluation of alternative policy initiatives is considered in this work. It employed a computer-based, fuzzy multi-criteria impact assessment tool for the...

fuzzy: A program for performing qualitative comparative analyses (QCA) in Stata
Provedor de dados: 31
Autores: Longest,   Kyle C.; Vaisey,   Stephen.
Qualitative comparative analysis (QCA) is an increasingly popular analytic strategy, with applications to numerous empirical fields. This article briefly discusses the substantive motivation and technical details of QCA, as well as fuzzy-set QCA, followed by an in-depth discussion of how the new program fuzzy performs these techniques in Stata. An empirical example is presented that demonstrates the full suite of tools contained within fuzzy, including creating configurations, performing a series of statistical tests of the configurations, and reducing the identified configurations.

Pobres no Campo, Ricos na Cidade? Uma Análise Multidimensional da Pobreza
Provedor de dados: 123
Autores: Costa,Rodolfo Ferreira Ribeiro da; Costa,Genivalda Cordeiro.
Resumo: O objetivo deste trabalho é identificar se existe uma relação entre os níveis de pobreza rural e urbano. Para isso, primeiramente foi auferido o patamar de pobreza para ambos os espaços, baseado na definição de pobreza multidimensional, admitindo, portanto, que as carências em saúde, renda, educação e moradia são componentes fundamentais para mensuração das privações. A abordagem utilizada para o indicador de pobreza multidimensional foi a lógica fuzzy, enquanto que a análise de dependência entre os indicadores foi desenvolvida através da função Cópula. Os dados remetem as áreas rurais e urbanas dos 5.565 municípios brasileiros em 2010. Por um lado, verificou-se que aquelas áreas rurais com maiores carências se fazem presentes na região Nordeste,...

Operations scheduling of sugarcane production using fuzzy GERT method (part II: preserve operations, harvesting and ratooning)
Provedor de dados: 111
Autores: Monjezi, Nasim; Sheikhdavoodi, Mohammad Javad; Zakidizaji, Hasan; Marzban, Afshin; Shomeili, Mahmood.
This paper presents a GERT method based on fuzzy theory for solving fuzzy project scheduling of sugarcane production (preserve operations, harvesting and rationing) in Khuzestan province of Iran. In this method, activity duration time and loops, repetition number, and output activities from nodes of network belong to a fuzzy set. First, an analytical approach was proposed to simplify the structure of network. Then, GERT network computations were done based on evaluating nodes. Process outputs were scheduled network and project fuzzy completion time. These outputs were fuzzy numbers and can be analyzed by α- cut. Results prove that the method of using fuzzy numbers and fuzzy relation in project scheduling is a powerful tool to estimate time for agricultural...

Methodological development of a quality index for agricultural operations, for corn cultivation using multi-criterion analysis
Provedor de dados: 42
Autores: Lamparelli,Rubens A.C.; Dias,Hugo S.
One of the major problems in the Brazilian agriculture is related to the production loss in the field, which, due to many factors, is not being considered. This article has the objective to develop a methodology to identify a quality index which integrates some crop quality variables which are able to indicate how the crop is developing in terms of loss in the field. The results have showed that the strategy of multi-criterion analysis and Fuzzy logic proved to be important tools for the assessment and preparation of a quality index for corn production. The index proposed performed well in representing the quality of agricultural operations when compared with reality.

Ecological capability evaluation for afforestation and forest expansion using Geographic Information System (GIS) in management area of Caspian Sea
Provedor de dados: 42
Autores: HASHEMI,SEYED A.
Abstract Ecological capability evaluation is referred to as evaluation of potential capability of land and determination of its natural land use. In this paper, ecological capability of Lille Basin in Lahijan was evaluated for afforestation and forest expansion using Geographical Information Systems (GIS). For this purpose, information layers (slope, elevation, geographical directions, temperature, rainfall, humidity, soil type, and canopy cover) were prepared by digitizing the data obtained from concerned organizations. First, the layers were prepared based on coordinate systems and pixel value. Then, they were standardized using fuzzy membership functions. The evaluation criteria were prioritized with regard to expert opinion, and by using multi-criteria...

ABSTRACT Handover is the key procedure in wireless networks to provide required qual ity of service to the users during mobility Handover. As the current scenario of wireless communication comprises of heterogeneity in architecture, application and radio access technologies concentrating on vertical handover becomes important to provide continuous communication and ubiquitous coverage .This paper provides comprehensive survey of the vertical handover, decision technique and parameter used for making proper handover in horizontal and vertical handover . The recent handover schemes are discussed and classified which varies based on concepts and the adopted schemes. A Fuzzy based decision making algorithm is proposed to made the handover decision more...
