“…The process of the fuzzifier, inference and defuzzifier of our model is demonstrated in Fig. 1 that it has derived from a generic example presented by Zafiropoulos and Dialynas (2005) and Khanlari et al (2008) with two inputs and a single output (with this difference that in our paper the product is used for the implication method and center of maximum for the defuzzification). In the fuzzifier, the crisp inputs are fuzzified into linguistic values.…”

“…But inventory managers are still confused in adopting policies on this class, since either no discussion has been held over determining the certain OPs of class B, or this issue has been discussed with ambiguity. In this paper, the certain suitable ordering systems for the items of classes A and C are first presented, and then fuzzy rules are extracted for such policies using the Zafiropoulos and Dialynas approach (2005) and Khanlari, Mohammadi, and Sohrabi (2008). Next, by means of these rules, the suitable policies are presented for the items of class B as well.…”

“…A manutenção preventiva objetiva evitar problemas inesperados durante o uso, minimizando o custo total de inspeção e reparo (Khanlari et al, 2008). Caso não seja realizada, é necessário proceder à manutenção corretiva, a qual visa corrigir falhas e é uma estratégia usada para reparar ou substituir partes (Blanchard et al, 1995).…”

RESUMO -O processo de especificação de materiais de construção exige dos profissionais um conhecimento cada vez mais amplo, e, quando correlacionada ao conceito de sustentabilidade, a sistematização de indicadores torna-se uma ferramenta de fundamental importância para a escolha responsável dos materiais construtivos. Esta pesquisa teve por objetivo sistematizar os indicadores potencialmente aplicáveis em um processo de seleção de materiais de construção com base na sustentabilidade. Para a definição dos mesmos foram adotadas como referências as principais ferramentas de avaliação de sustentabilidade, e, para o estabelecimento do alicerce conceitual, foram consideradas as fontes com reconhecida confiabilidade, oriundas principalmente de livros e artigos científicos nacionais e internacionais. A partir da sistematização, foi efetuada a correlação dos indicadores com as dimensões ambiental, econômica, social e cultural do conceito de sustentabilidade. Também foi feita uma análise complementar apontando as etapas do ciclo de vida em que os indicadores atuam para que a sustentabilidade seja favorecida. Como resultado principal, foram listados e conceituados 33 indicadores, sendo perceptível a maior relação dos indicadores com a dimensão ambiental da sustentabilidade. Também foi possível verificar que os indicadores se correlacionam de forma proporcional com as etapas do ciclo de vida, com exceção da etapa Uso/Operação, visto que nesta ocorre menos manipulação do material.Palavras-chave: indicadores de sustentabilidade, materiais de construção, seleção de materiais. ABSTRACT -The process of specifying construction materials requires from professionals an increasingly broad knowledge and, when correlated to the concept of sustainability, the systematization of indicators becomes a tool of fundamental importance for the responsible choice of building materials. This investigation aims to systematize the indicators potentially applicable in a process of selection of building materials based on sustainability. For the definition of these indicators we adopted the main tools for sustainability assessment as references. For the establishment of the conceptual foundation we considered the sources with known reliability, mainly from national and international books and scientific papers. On the basis of the systematization, we established the correlation between the indicators and the environmental, economic, social and cultural dimensions of the concept of sustainability. We also made a complementary analysis pointing out the stages of the life cycle in which the indicators help to favor sustainability. As a major result, 33 indicators were listed and appraised, where a greater relation of the indicators with the environmental dimension of sustainability can be noticed. It was also observed that the indicators are correlated in a proportional manner with the stages of the life cycle, with the exception of the Use/Operation step, in which there is less manipulation of material.

“…Corrective maintenances fireman maintenance is performed when the action is taken to restore the previous functionality. This type of maintenance is known as a reactive approach because the action is started when the unscheduled event happens (Khanlari et al 2007). Preventive maintenance includes repair, replacement, and maintenance of equipment to avoid unexpected failure during use (Mann et al 1995).…”

The present research aims at predicting the required activities for preventive maintenance in terms of equipment optimal cost and reliability. The research sample includes all offshore drilling equipment of FATH 59 Derrick Site affiliated with National Iranian Drilling Company. Regarding the method, the research uses a field methodology and in terms of its objectives, it is classified as an applied research. Some of the data are extracted from the documents available in the equipment and maintenance department of FATH 59 Derrick site, and other needed data are resulted from experts' estimates through genetic algorithm method. The research result is provided as the prediction of downtimes, costs, and reliability in a predetermined time interval. The findings of the method are applicable for all manufacturing and non-manufacturing equipment.
