In previous works we proposed a distributed architecture, based on autonomous agents, in order to model cooperation activities between product designers and supply chain partners in product development stage. The multi agent system aims to choose a product from a set of product's alternatives, the optimal one according to its supply chain costs. The proposed agents are imbedded with optimization models that minimizes costs and specifies selected nodes and activities assigned to each supply chain partner. Unfortunately, costs are not a decisive criterion, many criteria should be integrated to choose the optimal product design like environmental criteria. In this paper, we present a new model that integrate the environmental constraints in product selection. Consequently, we propose to adopt a multi criteria decision method to reduce the number of product's alternatives proposed by product designers based on environmental criteria, then costs' optimization can be done to select the best product design. The goal is to avoid the huge simulation time that can generate costs' optimization for all proposed product designs and at the same time we select an eco-friendly design with optimal costs.","PeriodicalId":433166,"journal":{"name":"2018 4th International Conference on Optimization and Applications (ICOA)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127481977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Admittedly, they are subjected to repeated loadings, but, after a number of cycles, they fail due to a phenomenon called fatigue. The fatigue strength is commonly represented by the Wohler curve which is a plot of stress range against cycles to failure. Many parameters affect the fatigue of welded structures: The detail geometry, the stress concentration, the condition assumptions, the material properties, the welding process, the residual stress, and the environment. In this paper, a three-dimensional finite element method were built to calculate the stress and to evaluate the effect of the major factors that influence the fatigue strength on a structure based on welded rectangular profiles under damped loads. The results indicated the evolution of loading history as a function of available number of cycles. Also, we have demonstrated the influence of the spring stiffness on durability of our model; indeed, as the number of cycles increases the spring stiffness increases.","PeriodicalId":433166,"journal":{"name":"2018 4th International Conference on Optimization and Applications (ICOA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125363105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of our work is to help Radiologists in the treatment of brain MRI images, by detecting locating and giving the exact characteristics of a tumor areas. This is to cope with the very large number of images that have to be processed every day. Thus we can reduce the treatment time and the patients waiting time. The burden has become less heavy with the step automation. In this article we present a new fast and totally automatic tumor detection and extraction method, our work is divided into two parts: In the first time we will filter the image by the Nl-means filter to reduce the confusion risk and to soften the image. And in the second step we will classify the MRI into two classes (tumor classes and no tumor classes), this step will be done by the expectation maximization algorithm (EM). At the last time and to prove our method effectiveness a multiple evaluation criteria will be calculate, to compare our method to seven tumor extraction method which are the frequently extraction methods used in the literature and the tree last extraction methods proposed recently.","PeriodicalId":433166,"journal":{"name":"2018 4th International Conference on Optimization and Applications (ICOA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122922173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
