Correspondingly globalization has introduced the opportunity to do business with suppliers the world over, allowing greater access to a host of untold products and services - that can provide a competitive advantage to the OEM, which enables them delivering increased value to their clients. Nevertheless, a global sourcing strategy has introduced a set of risks well beyond what was typical in the traditional suppler chain. The question is how does a company engage in global sourcing and yet gain the benefits while weighing and managing risks. Beyond assessing the risk of a supplier and their supply, there are opportunities to collaborate and assess a supplier's level of resiliency, and where appropriate engage in actions of remediation. 3 Business Continuity Planning & Supply Chain Risk – An Overview Managing Risk is an imperative for Business Continuity Planning RISK is one of the SIX mega-trends impacting IBM Chief Supply Chain Officer Study Identified The enterprises around the world Top Five Challenges Major factors affecting the enterprise today Risks, both operational and financial, is the #2 1.

  • A Reactive Performance Monitoring Framework
    A Reactive Performance Monitoring Framework Katherine ChengLi Directed By: Prof. Liam Peyton Thesis Submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfillment of the requirements for the degree of Master of Computer Science University of Ottawa Ottawa, Ontario, Canada June 2016 © Katherine ChengLi, Ottawa, Canada, 2016 Abstract With the ascendency of data and the rise of interest in analytics, organizations are becoming more interested in the use of data to make their business processes more intelligent and reactive. BI applications are a common way that organizations integrate analytics in their processes. However, it can be days, weeks or even months before a manual response is undertaken based on a human interpreting a report. Even when information technology supports automatic responses within an organization, it is often implemented in an ad hoc manner without following a systematic framework. In this thesis, we present a reactive performance monitoring (RPM) framework which aims at automating the link from the analytical (how well is the operational achieving the strategic) to the operational (the particular process steps implemented within an organization that determine its behavior) aspects of businesses to bypass the strategic (the high level and long term goals an organization is trying to achieve) as needed and reduce the latency between knowledge and action. Our RPM framework is composed of an architecture, a methodology, and a rule environment which permits the redaction of rules possessing relevant conditions and actions. In addition, we present an OLAP rule engine which is demonstrated to be effective in our framework where events are streamed in, reacted upon in real-time, and stored in an OLAP database.

    NEWSLETTER OF THE FACULTY OF ENGINEERING AND DESIGN W inter 2010 Transforming a village Students take on the Batawa Initiative Students go Extreme Blue Gift creates a new lab Challenging the Wii Message from the dean ngineering and design are disciplines driven by societal needs, so naturally Eengineers and designers must be closely engaged with the communities they serve. Civil engineers are keenly aware of the people their structures must safeguard; biomechanical engineers share the joy of patients whose mobility has been restored; architects create spaces in which the drama of life is played out. Whether working with industry partners, research collaborators, philanthropists, granting agencies, mentors or clients, we are connected to the needs—and dreams— of our community. In this issue of Ingenious, that is most obvious in the work that architecture and industrial design students are doing to revitalize a small Ontario town. The Batawa Initiative is an innovative approach that utilizes the skills of our creative students to enhance both their education and the community. Community connections are also emphasized through the partnerships the Faculty forms to address the pressing needs of society. Tony Bailetti is leading a high-tech community initiative to help fledgling companies commercialize communications-enabled applications (read about Coral CEA on page 12); the interdisciplinary Sustainable Energy Research Centre brings together experts from Message from the dean Message from engineering and design and the Faculty of Public Affairs (page 9); and researchers across Canada, including a Carleton team, are working to harness technology to enhance healthcare (page 10). Over the past months, I have had numerous occasions to be reminded of Carleton’s connection to the community—and the impact our alumni and partners have on the university.
