When the degradations of multiple parameters of a product is taken into account, traditional univariate degradation prediction method is not applicable, especially when the parameters are correlated. To cope with this problem, Mahalanobis distance is proposed, to combine multiple parameters into one unified index. Then healthy baselines of the product are determined based on the unified index. Finally, the method of Relevance Vector Machines is applied to predict the change trend of the unified index and find the failure time. A case study is presented to prove the validity of our proposed method.","PeriodicalId":354846,"journal":{"name":"2017 IEEE International Systems Engineering Symposium (ISSE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127991995","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}

As elements of a factory are connected via a complex network of relations and flows, single changes can have an impact on the entire manufacturing system. In order to enable a successful change management, companies need to understand and consider all possible change impacts. For this purpose, this paper presents a method for change impact analysis in factory systems. By combination of manufacturing system modeling and a network of manufacturing metrics, change impacts on arbitrary metrics can be estimated. The definition of constraints between factory element properties improves the certainty of the analysis' results. Consecutive required changes are applied directly to the model and are equally considered in the change impact analysis. In an exemplary scenario, the applicability in principle of the approach is demonstrated, but also, current limitations and further research activities are identified.","PeriodicalId":354846,"journal":{"name":"2017 IEEE International Systems Engineering Symposium (ISSE)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128091117","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}

First, skin-color region is detected. After morphological operations, unnecessary noise is removed, and the method of seed region growing is used to mark pixel blocks. Then the skin-color region is determined whether or not each block is a human face. If it is not human face, it is discarded. Otherwise, wavelet transform is used to decompose the face image. A low-frequency sub-band face image is captured by wavelet transform, and two-dimensional principle component analysis (2DPCA) is used to recognize head posture. Face color histograms are used to build face models, and faces are traced by the self-organizing hierarchical particle swarm optimizer with time-varying acceleration coefficients (HPSO-TVAC) algorithm. In order to solve the face masking problem, adaptive seeking windows are applied. When a human face is not detected, a large seeking window will be used, which will zoom in or out depending on the best global fitness.","PeriodicalId":354846,"journal":{"name":"2017 IEEE International Systems Engineering Symposium (ISSE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132110731","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}

Background: When operators are overwhelmed by stress, their perceptions, thinking, and judgments are impaired, increasing the chance of misinterpretation of events and increasing the potential for human error. The \"intelligent control room\" has been proposed as a possible solution for helping operators to deal with such stress. The control room comprises a variety of components used to monitor the operator and infrastructure under his/her control in an effort to optimize the performance of the humantechnical system as a whole. A critical component of this control room solution is the provision of human monitoring and assessment data in order to determine the operator's situation awareness. Methods: An emotion recognition system is designed based on two Deep Learning models, the Bidirectional Long Short Term Memory network (BiD-LSTM) and the Deep Convolutional Neural Network (DCNN), in order to process audio and facial data respectively. The system is first validated against a standard corpus of expert-coded emotion data. Post-validation, a dataset of expert-coded user stress data is coded by the system for emotional valence, and these system-generated emotional readings are compared to the expert-coded stress markers to determine any significant correlations. Contribution: This research contributes to developing the idea of intelligent and automated decision-making support in situational awareness measurement systems. Such systems support users by real-time collecting and processing data, and assist decision-making based on operator behavioral patterns.","PeriodicalId":354846,"journal":{"name":"2017 IEEE International Systems Engineering Symposium (ISSE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129795790","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}

This discipline aims at evaluating several aspects of interactions among humans and system components to ensure long term human well-being. The robust human posture analysis is a crucial step towards achieving this target. In this paper, the deep representation learning paradigm is used to analyze the articulated human posture and assess the risk of having work-related musculoskeletal discomfort in manufacturing industries. Particularly, we train a deep residual convolutional neural network model to predict body joint angles from a single depth image. Estimated joint angles are essential for ergonomists to evaluate ergonomic assessment metrics. The proposed method applies the deep residual learning framework that has demonstrated impressive convergence speed and generalization capabilities in addressing different vision tasks such as object recognition, localization and detection. Moreover, we extend the state-of-the-art data generation pipeline to synthesize a dataset that features simulations of manual tasks performed by different workers. An inverse kinematics stage is proposed to generate the corresponding ground truth joint angles. Experimental results demonstrate the generalization performance of the proposed method.","PeriodicalId":354846,"journal":{"name":"2017 IEEE International Systems Engineering Symposium (ISSE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122344629","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}
