“…EERPFAnt is based on fuzzy logic [14] and the ant colony optimization [15] to propose a routing protocol for DTN network, which allows nodes to choose intelligently the relays that have the great chance to carry the message closer to its final destination .The forwarding strategy depends on the energy level and the number of messages to be delivered before encountering the message destination using information on nodes that have already received a copy of the message and the fuzzy logic to decide whether the encountered node should carry the message or should wait to meet one of the nodes that have already received a copy. With this new strategy DTN nodes will be able to save energy due to the operation of transmission and reception of message copies when one of the nodes which have already received a copy have managed to deliver it to its final destination.…”

Abstract-The messages routing in a DTN network is a complicated challenge, due on the one hand of intermittent connection between the nodes, the lack of the end-to-end path between source / destination and on the other hand, the constraints related to the capacity of the buffer and the battery. To ensure messages delivery in such an environment, the proposed routing protocols use multiple copies of each message in order to increase the delivery ratio. Most of these routing protocols do not take into account the remaining energy of nodes and the history on the relays that have already received a copy of the message in order to select the nodes that will participate in the message routing. This paper proposes a new approach named EERPFAnt inspired by the ant colony intelligence and improved by the fuzzy logic technique to select the best relay by combining the energy level of the nodes, as well as the information on the relay that have already received a copy of the message to estimate intelligently, the energy level of the nodes at the time of encounter with the desired destination. Simulation results will show that the proposed approach performances are better than those of Epidemic routing protocols, Spray and Wait and ProPHET.

“…Porém, apesar de sua importância, muitos engenheiros industriais ainda não conhecem os elementos essenciais que possibilitam o máximo desempenho da mesma (BLACK, 1999). Para Susilawati et al (2015), ainda é pequeno o número de pesquisas que meçam o grau lean em células em seus diferentes aspectos, existindo inclusive necessidade de aprofundamento nos aspectos humanos, de treinamento e de gestão do Mediante ao contexto apresentado, evidencia-se que estudos associados ao grau de maturidade de células que atuam segundo a filosofia lean são de grande valia e pouco explorados.

Resumo:No ambiente competitivo atual, as empresas são forçadas a elevar constantemente o grau de competitividade de sua produção e, nesse sentido, a filosofia lean é de grande valia. Entretanto, é escasso na literatura o número de referências que possuam como foco a análise do nível de maturidade de células que operam de acordo com a referida filosofia. Devido à importância dessa temática, o presente artigo tem como objetivo realizar uma revisão da literatura procurando evidenciar quais são os parâmetros relevantes para avaliar a maturidade de células de manufatura que operam segundo a filosofia lean. Para isso, foram analisados diversos artigos e uma lista foi estruturada. Tais parâmetros foram divididos em grupos de acordo com suas similaridades. Entre os parâmetros levantados, destacam-se as ergonomias física e cognitiva e a sustentabilidade. Os parâmetros obtidos como resultado desta pesquisa podem ser utilizados como um ponto de partida para a avaliação de células de manufatura lean.Palavras-chave: Produção Enxuta.

Abstract:In the current competitive environment, companies are being forced to increase constantly their production competitiveness level and, in this sense, lean philosophy is of great value. However, it is scarce in the literature the number of references which is focused on the analysis of the maturity level of manufacturing cells that operate according to the referred philosophy. Due to the relevance of this theme, the present article aims to review the literature in order to define which parameters must be considered to evaluate the maturity of lean manufacturing cells. To this end, articles were analyzed and a list of important parameters to evaluate lean cells was structured. These parameters were divided in groups according to their similarities. Among these parameters, it highlights the physical and cognitive ergonomics and the environmental sustainability. The obtained parameters as a result in this research can be used as a starting point to an evaluation of lean manufacturing cells. Mediante ao contexto apresentado, evidencia-se que estudos associados ao grau de maturidade de células que atuam segundo a filosofia lean são de grande valia e pouco explorados. Visando contribuir com a temática, este artigo almeja realizar uma revisão da literatura a fim de estruturar uma lista com parâmetros essenciais para avaliar a maturidade das referidas células. Tal lista poderá ser utilizada por pesquisadores em futuras pesquisas e por profissionais de mercado. REVISÃO DA LITERATURA Filosofia lean e manufatura celularEste tópico será dedicado a uma rápida explanação sobre os princípios da filosofia lean e definições iniciais sobre manufatura celular. A listagem completa dos parâmetros essenciais para avaliação da maturidade de células lean será caracterizada como resultado desta pesquisa e, em função disto, será apresentada A formação de células a partir de famílias de produtos, a definição dos layouts das células, o planejamento das operações das célul...

“…In situations such as this, performance measurement or evaluation models can be used as a solution tool. Performance measurement is an important issue for management and it is mainly used for monitoring existing performance, identifying the gap between expected and existing performance, identifying performance improvement opportunities and supporting continuous improvement, providing information for long-term decisions and enabling interaction between processes and stakeholders [3]. The aim of this study is to propose a flexible, dynamic and practical performance evaluation tool from management and organization viewpoint for SMEs.…”

Companies need to constantly evaluate their activities in strategic planning process. These activities include all processes in the company, such as management and organization, research and development, production planning, manufacturing, post-sales services, accounting and finance. The aim of this study is to propose an evaluation model that can be used to evaluate management and organization performance for small and medium enterprises. In the proposed model, fuzzy multi-criteria decision-making approaches consisting of fuzzy analytic network process and fuzzy decision making trial and evaluation laboratory methods are used to determine the weights of performance criteria. A case study has been conducted in a small and medium enterprise for empirical evidence. From the outcome of our investigation, it is possible to conclude that "corporate communication" and "process management" are more important criteria. The most important sub-criteria are listed as, "senior management in harmony with each other", "employee requests and demands are collected periodically" and "pocket reference that includes procedures and fixed rules are available".
