However, due to the inherent stochasticity of customer demands as well as other influencing factors, factories are still facing dynamic and complex challenges related to their production management. Among which, machine failure is one of the most significant problems. Therefore, this research investigates a novel solution through incorporating the concept of Industry 4.0 (I4.0) into a manufacturing process, where reconfigurable machines are used to compensate for the production loss of a dedicated production line due to machine failure. A simulation-based approach is developed with the help of FlexSim in order to examine two general configurations with respect to three key performance indicators (KPIs). The results illustrate, by properly adopting the concept and technologies of I4.0, the performance of a manufacturing process can be improved to better react to unexpected events in production. From both technical and operational perspectives, several recommendations for further development are given in this paper.","PeriodicalId":395378,"journal":{"name":"2021 IEEE/SICE International Symposium on System Integration (SII)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129180627","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}

Such consistencies become more important in the case of multiple screen teleoperation systems, where the operator can change the primary view, for example, among overhead view, side view, and hand camera view, depending on the situation.In this paper, we propose a unified method of master controller that is consistent to the primary view in multiple screen teleoperation systems. We first propose a method for constraining the posture of the master controller during indexing operation in the master-follower mode so that posture consistency can be preserved even when master-follower connection is disengaged. This constraining method will also be applied when the operator changes primary view so that the master controller will be constrained to the posture with respect to a new reference frame. We also propose to assign an appropriate control mode (either position mode or velocity (joy-stick) mode) depending on the selected primary view, where control modes for translational motion and rotational motion are considered separately. We have verified the effectiveness of the proposed method by experiments.","PeriodicalId":395378,"journal":{"name":"2021 IEEE/SICE International Symposium on System Integration (SII)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129594182","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}

MHDP is a type of multimodal latent variable models, e.g., multimodal latent Dirichlet allocation and multimodal variational autoencoder, that enables a robot to perform unsupervised multimodal object categorization on the basis of different types of sensor information. The goal of the active exploration is to reduce the number of actions executed to collect multimodal sensor information from a variety of objects to acquire knowledge on object categories. The active exploration method employing the information gain (IG) criterion for MHDP is described by extending the IG-based active perception method. Exploiting the submodular property of IG in MHDP, greedy and lazy greedy algorithms with a certain theoretical guarantee of performance are proposed. The effectiveness of the proposed method is evaluated in a robot experiment. Results show that the proposed active exploration method with the greedy algorithm works well, and it significantly reduces the step for exploration. Further, the performance of the lazy greedy algorithm is found to deteriorate at times, due to the estimation error in the IG, differently from that of active perception.","PeriodicalId":395378,"journal":{"name":"2021 IEEE/SICE International Symposium on System Integration (SII)","volume":"293 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116004510","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}

In a typical self-localization system, a DCN is trained as a visual place classifier from past visual experiences in the target environment. However, its classification performance can be deteriorated when it is tested in a different domain (e.g., times of day, weathers, seasons), due to domain shifts. Therefore, an efficient domain-adaptation (DA) approach to suppress perdomain DA cost would be desired. In this study, we address this issue with a novel “domain-shift localization (DSL)” technique that diagnosis the DCN classifier with the goal of localizing which region of the robot workspace is significantly affected by domain-shifts. In our approach, the DSL task is formulated as a fault-diagnosis (FD) problem, in which the deterioration of DCN-based self-localization for a given query image is viewed as an indicator of domain-shifts at the imaged region. In our contributions, we address the following non-trivial issues: (1) We address a subimage-level fine-grained DSL task given a typical coarse image-level DCN classifier, in which the target DCN system is queried with a region-of-interest (RoI) masked synthesized query image to diagnosis the RoI region; (2) We extend the DSL task to a relevance feedback (RF) framework, to perform a further query and return improved diagnosis results; and (3) We implement the proposed framework on 3D point cloud imagery-based self-localization and experimentally demonstrate the effectiveness of the proposed algorithm.","PeriodicalId":395378,"journal":{"name":"2021 IEEE/SICE International Symposium on System Integration (SII)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123803380","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}
