作者： Wollmann, Dewey Steiner, Maria Teresinha Arns Steiner Neto, Pedro José Gouvea Da Costa, Sérgio Eduardo Pontifical Catholic University of Paraná Polytechnic School Graduate Program in Industrial Engineering and Systems Curitiba PR Brazil Federal University of Parana Graduate Program in Business Curitiba PR Brazil

An industrial enterprise in a competitive environment undergoing constant change, which wishes to be recognized as World Class, needs a management model that affords its executives a systemic vision. Aware of the need to define an effective and efficient model to manage a company, executives should always ask how it should be defined, implemented and continuously evaluated. In this context, the article presents a computer system, referred to herein as the Socrates CEO Robot, based on the scientific conceptual model (Complex Adaptive systems Integrating the Decision Making Process in Industrial Companies) presented by Wollmann and Steiner (2014). The capacity of Socrates to aid the integrated and systemic decision process is verified in competitive business environments of the e-tangram business simulator. The results show that Socrates is capable of managing an industrial enterprise in a virtual competitive environment generated in a business simulator (usually referred to as a business game).

With the advance of network technology in recent years, the dissemination and exchange of massive documents has become commonplace. Accordingly, the importance of content analysis techniques is increasing. Topic analysis in large-scale document streams such as E-mails and news articles is an important research issue. This paper addresses techniques for "topic activation analysis" for document streams. For example, when news articles with a strong relationship to a given topic arrive frequently in a news stream, we can regard the activation level of the topic as high. In [I], Kleinberg proposed a method for analyzing document streams. Although the main objective of his method was to detect bursts of topics, it can also be used for topic activation analysis. His method, however, has a serious limitation in that it only looks at the arrival rate of documents and ignores the degree of relevance for each document. Another limitation is that his method is "batch-oriented." This paper first proposes a novel topic activation analysis scheme that incorporates both document arrival rate and relevance to address the first problem. It then presents an incremental scheme more appropriate for a document streaming environment. The proposed schemes are validated by experiments using real CNN news articles. Copyright 2005 ACM.

This paper aims at proposing and comparing two fuzzy models and a statistical model for clustering based on L1-space. Clustering methods in the fuzzy models are the standard fuzzy c-means and an entropy regularization method based on L1-space. Furthermore, we add new variables to them for improving the cluster division. In the statistical model, a mixture distribution model based on L1-space is proposed and the EM algorithm is applied. © Springer-Verlag Berlin Heidelberg 2001.

The technological paradigm shift is supporting the digital transformation of manufacturing, characterized by emerging industry 4.0 technologies, and the inherent complexity in selecting appropriate technologies. This increasing complexity of technologies, the multiple and conflicting decision criteria, and the abundance of technology alternatives demand a structured process for managers to select technologies to be acquired and implemented. This work derived from the observation of a real problem in a recognized world class automaker company. The identified problem consists in a lack of a consolidated process (procedure) to support managers and specialists in selecting industry 4.0 technologies. This paper aims at extending theory concerning technology management and selection, by proposing a research agenda regarding the solution for the defined problem. A systematic literature review (SLR) is performed to support it, comprising the analysis and synthesis of a review portfolio. The construction of a structured procedure for industry 4.0 technology selection would serve two purposes: (i) to identify the most suitable technology to solve a specific problem, (ii) to support the creation of a technology roadmap to ground a long-term investment plan. The procedure should be able to deal with both purposes to support firms in a digital transformation journey, enabling an objective, rational and traceable decision-making process. © 2021 IISE Annual Conference and Expo 2021.

This article aims to analyze the innovation scores of IT companies and their respective clusters, resulting in a tool for constructing knowledge about these companies and gaining useful information for comparison purposes, since few studies are focused on innovation in Brazilian IT companies, especially microenterprises. A case study methodology was used in this research, and to measure innovation, the model proposed by Edison, Ali and Tonkar (2013) was used. The target audience was the LPA of information technology companies in southwest Paraná, being composed of 50 companies divided into 3 clusters. The data collection was based on a survey with 43 questions built according to the Likert Scale. As a result of the application of the Kruskall-Wallis test, with 5% significance, it was observed that there is a difference between the innovation scores of each cluster, with Clusters 1 and 3 having higher scores. As for the relationship between innovation and turnover, the Spearman Correlation test, with 5% significance, showed that there is a moderate relationship between innovation scores and company turnover. Measuring innovation, both individually and in clusters, is important in the information technology sector because it allows management to see weaknesses and strengths, and implement improvements and changes that ensure increased competitiveness and permanence in the market. © 2017 DEStech Publications.

Journal of Biomaterials and Nanobiotechnology 2011年第4期2卷 337-346页

作者： Kazuo Sugiyama Nobuyuki Tanigawa Kohei Shiraishi Cluster of Biotechnology and Chemistry Systems Program in Systems Engineering Graduate School of Systems Engineering Kinki University

Amphiphilic block copolymers poly(LysAA-b-DMS) consisting of a hydrophilic poly(N-α-acrylamide-L-lysine) [poly(LysAA)] segment with different molecular weights and a hydrophobic polydimethylsiloxane (PDMS) segment were prepared as follows. The precursor copolymer poly(Boc-LysAA-OtBu-b-PDMS) was obtained from radical polymerization of N-α-acrylamide-N-ε-tert-butoxycarbonyl-L-lysine-tert-butylester (Boc-LysAA-OtBu) initiated with 4,4’-azobis(polydimethylsiloxane 4-cyanopentanoate) (azo-PDMS) with the molecular weight of PDMS Mw = 4.3 × 103 in the presence of 2-mercaptoethanol (2-ME) as a chain-transfer agent. Removal of the protecting groups of the precursor copolymer was carried out in 80% trifluoroacetic acid aqueous solution to give poly(LysAA-b-DMS)-1-3. The weight average molecular weight of poly(LysAA-b-DMS)-1-3 was Mw = 1.02 × 104 – 2.52 × 104. From the 1H-NMR and fluorescence spectra measurements, poly(LysAA-b-DMS)-1-3 was determined to self-organize and form core-shell micelles in water. The critical micelle concentration (CMC) increased to 1000 - 4000 mg·L–1 with increasing molar ratio of the poly(LysAA) segment from 0.42 to 0.65. From morphological analysis with a scanning probe microscope (SPM), poly(LysAA-b-DMS) has microphase-separated structures made up of hydrophilic and hydrophobic regions with the domain size ranging from several tens to several hundreds of nanometers. Inhibition of thrombin activity of poly(LysAA-b-DMS) was evaluated from the Michaelis constant (KM) and catalytic activity (kcat) for the enzymatic reaction of thrombin and synthetic substrate S-2238 in the presence of poly(LysAA-b-DMS). The KM and kcat were 0.10 - 0.11 mM and 4.04 × 105 – 4.26 × 105 min–1, respectively. Fibrinolytic activity was also verified from the transformation of plasminogen to plasmin by tissue plasminogen activator (t-PA) using synthetic substrate S-2251 in the presence of poly(LysAA-b-DMS). The KM and kcat were 0.07 mM and 5.73 × 106 –5.95 × 106 min–1, respec

At a time when the competitive market is operating rapidly, manufacturing industries need to stay connected, have interchangeability and interoperability in their factories, ensuring that there is heterogeneous communication between sectors, people, machines and the client, challenging the manufacturing industry to discover new ways to bring new products or improve their manufacturing process. Precisely because of the need to adjust to these new market demands, factories pursue complex and quick decision-making systems. This work aims to propose applications of Machine Learning techniques to develop a decision-making platform applied to a manufacturing line reducing scrap. This goal will be achieved through a literature review in the fields of Artificial Intelligence (AI) and Machine Learning to identify core concepts for the development of a failure prediction system. This research has demonstrated the problems and challenges faced by manufacturing daily, and how, through the application of AI techniques, it is possible to contribute to assist in these problems by improving quality, performance, scrap rates and rework, through connectivity and integration of data and processes. This paper contributes to evaluate the performance of machine learning ensembles applied in a real smart manufacturing scenario of failure prediction. © 2020, IFIP International Federation for Information Processing.
