A psychological wellness index integrates the survey results that measure stress, depression, anger, and fatigue. The current model is based on a multiple regression method and manually constructs a cause and effect model of the psychological wellness. However, this constructed model depends upon the survey responses. The relationship between these survey responses and psychological wellness indices are not linear due to data imbalance. When any data inconsistency exists, the reliability of the model decreases and eventually cost of maintenance on model revision increases. Also, when new variables or data entries are considered, the entire model should be constructed again. This paper examines the feasibility of machine learning algorithms to predict the psychological wellness indices based on the reconstructed responses. In this paper, four machine learning algorithms including multi-layer perceptron, support vector regression, generalized regression neural network, and k nearest neighbor regression, are compared and the experiment results are presented.","PeriodicalId":135246,"journal":{"name":"Proceedings of the 2014 International Conference on Innovative Design and Manufacturing (ICIDM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123925516","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 wide application of MBD (Model Based Define) technique has expedited the utilization of optimizing tolerance. In this paper, we propose a new approach to optimize tolerance of multiple processes based on MBD technique. The main features include (a) the subordinate relationship between processes model and tolerance information is analyzed and a model chaining them together is established, and (b) a revised Taguchi quality loss function is adopted to reflect the real quality distribution of mass product. A case study shows that this approach could, we believe, improve the steady of processes of product manufacturing, and make the manufacturing more economical.","PeriodicalId":135246,"journal":{"name":"Proceedings of the 2014 International Conference on Innovative Design and Manufacturing (ICIDM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121340134","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 splicing device and automatic control system are designed as well. After the theoretical analysis of intimate contact and autohesion processes is investigated, the key parameters which mainly affect the quality of splicing processes are determined. They are temperature, pressure, and time, respectively. Moreover, the influence mechanism of these three parameters on splicing quality is examined by experimental tests, based on which the appropriate values are selected to achieve the favorable performance of splicing zone.","PeriodicalId":135246,"journal":{"name":"Proceedings of the 2014 International Conference on Innovative Design and Manufacturing (ICIDM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127942789","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}
