    Innovation has at least 40 definitions, many of which can lay claim to being reliable and valid guidelines for organizations to make improvements by doing something new and different. Towards the goal of providing insights to facilitate fruitful pursuit of supply chain, the Third Annual World Class Supply Chain Summit focused on the theme of Innovation in a Complex, Uncertain World. At this invitation-only summit on May 9th, 2018 in Milton, Ontario, executives, scholars, and students discussed a range of innovation topics. The core of those discussions sought clarity on the following: The complexities, uncertainties, and challenges that are prompting the need for innovation in contemporary supply chains Effective ways for tapping into the potential to innovate New ideas from the next generation of researchers and practitioners Questions that demand rigorous research about innovation in supply chains The summit addressed those four issues with two keynote presentations, a panel discussion, and three-minute lightning talk presentations by five students (from the doctoral through to the undergraduate level). In addition to giving voice to the next generation (via the students’ 3-minute presentations), the summit was also designed to uncover perspectives from business disciplines outside of supply chain management (SCM). This was reflected mainly in the inclusion of panelists whose expertise on the subject of innovation was built in the field of entrepreneurship. Incorporating perspectives from the next generation and from beyond the traditional scope of SCM proved useful in generating some insightful conclusions. Among those conclusions, four of the main ones are: Effective usage of supply chain analytics has the potential to yield meaningful returns for transportation services providers The creativity necessary for innovation can be learned so employers should invest in cultivating creativity and its application to challenges of interest, particularly for new and young employees Though seemingly bewildering, the complexity and challenges in modern supply chains represent opportunity for innovation Innovations need not be revolutionary in order to be of real value to an organization firm and its stakeholders This white paper reports on (a) the underlying details of those points (e.g., specific real world examples presented to reinforce those points), (b) some critical unanswered questions that surround those points, and (c) potential research projects to address those questions. These helped to solidify the summit as a valuable contributor to industry-academia deliberations of relevance to the SCM field

    Logistics of Mathematical Modeling-Focused Projects

    This article addresses the logistics of implementing projects in an undergraduate mathematics class and is intended both for new instructors and for instructors who have had negative experiences implementing projects in the past. Project implementation is given for both lower and upper division mathematics courses with an emphasis on mathematical modeling and data collection. Projects provide tangible connections to course content which can motivate students to learn at a deeper level. Logistical pitfalls and insights are highlighted as well as descriptions of several key implementation resources. Effective assessment tools, which allowed me to smoothly adjust to student feedback, are demonstrated for a sample class. As I smoothed the transition into each project and guided students through the use of the technology, their negative feedback on projects decreased and more students noted how the projects had enhanced their understanding of the course topics. Best practices learned over the years are given along with project summaries and sample topics. These projects were implemented at a small liberal arts university, but advice is given to extend them to larger classes for broader use.Comment: 27 pages, no figures, 1 tabl

    Autonomous Fault Detection in Self-Healing Systems using Restricted Boltzmann Machines

    Autonomously detecting and recovering from faults is one approach for reducing the operational complexity and costs associated with managing computing environments. We present a novel methodology for autonomously generating investigation leads that help identify systems faults, and extends our previous work in this area by leveraging Restricted Boltzmann Machines (RBMs) and contrastive divergence learning to analyse changes in historical feature data. This allows us to heuristically identify the root cause of a fault, and demonstrate an improvement to the state of the art by showing feature data can be predicted heuristically beyond a single instance to include entire sequences of information.Comment: Published and presented in the 11th IEEE International Conference and Workshops on Engineering of Autonomic and Autonomous Systems (EASe 2014

    Application of six sigma methodology to reduce defects of a grinding process

    Get PDF
    Six Sigma is a data-driven leadership approach using specific tools and methodologies that lead to fact-based decision making. This paper deals with the application of the Six Sigma methodology in reducing defects in a fine grinding process of an automotive company in India. The DMAIC (Define–Measure–Analyse–Improve–Control) approach has been followed here to solve the underlying problem of reducing process variation and improving the process yield. This paper explores how a manufacturing process can use a systematic methodology to move towards world-class quality level. The application of the Six Sigma methodology resulted in reduction of defects in the fine grinding process from 16.6 to 1.19%. The DMAIC methodology has had a significant financial impact on the profitability of the company in terms of reduction in scrap cost, man-hour saving on rework and increased output. A saving of approximately US$2.4 million per annum was reported from this project

    Teaching and Learning Data Visualization: Ideas and Assignments

    Full text link
    This article discusses how to make statistical graphics a more prominent element of the undergraduate statistics curricula. The focus is on several different types of assignments that exemplify how to incorporate graphics into a course in a pedagogically meaningful way. These assignments include having students deconstruct and reconstruct plots, copy masterful graphs, create one-minute visual revelations, convert tables into `pictures', and develop interactive visualizations with, e.g., the virtual earth as a plotting canvas. In addition to describing the goals and details of each assignment, we also discuss the broader topic of graphics and key concepts that we think warrant inclusion in the statistics curricula. We advocate that more attention needs to be paid to this fundamental field of statistics at all levels, from introductory undergraduate through graduate level courses. With the rapid rise of tools to visualize data, e.g., Google trends, GapMinder, ManyEyes, and Tableau, and the increased use of graphics in the media, understanding the principles of good statistical graphics, and having the ability to create informative visualizations is an ever more important aspect of statistics education

    A personalized and context-aware news offer for mobile devices

    For classical domains, such as movies, recommender systems have proven their usefulness. But recommending news is more challenging due to the short life span of news content and the demand for up-to-date recommendations. This paper presents a news recommendation service with a content-based algorithm that uses features of a search engine for content processing and indexing, and a collaborative filtering algorithm for serendipity. The extension towards a context-aware algorithm is made to assess the information value of context in a mobile environment through a user study. Analyzing interaction behavior and feedback of users on three recommendation approaches shows that interaction with the content is crucial input for user modeling. Context-aware recommendations using time and device type as context data outperform traditional recommendations with an accuracy gain dependent on the contextual situation. These findings demonstrate that the user experience of news services can be improved by a personalized context-aware news offer

    Adaptive Guidance: Enhancing Self-Regulation, Knowledge, and Performance in Technology-Based Training

    Considerable research has examined the effects of giving trainees control over their learning (Steinberg, 1977, 1989; Williams, 1993). The most consistent finding of this research has been that trainees do not make good instructional use of the control they are given. Yet, today’s technologically based training systems often provide individuals with significant control over their learning (Brown, 2001). This creates a dilemma that must be addressed if technology is going to be used to create more effective training systems. The current study extended past research that has examined the effects of providing trainees with some form of advisement or guidance in addition to learner control and examined the impact of an instructional strategy, adaptive guidance, on learning and performance in a complex training environment. Overall, it was found that adaptive guidance had a substantial effect on the nature of trainees’ study and practice, self-regulation, knowledge acquired, and performance
