    It goes without saying that we live in a data-rich era; data is no longer a scarce resource. The number of devices connected to the internet is growing every day, increasing the growth rate of data even further. Technology providers urge organisations to invest in IT infrastructure and software to capture all that data with the potential of generating new insights, competitive advantage and increased revenues. To capture these advantages, data needs to be transformed into actionable insights and requires organisations to develop the right analytical capabilities. However, technology and…

    Those not in the academic world, may think that faculty, during the summer, when they are not officially teaching, are not working.This is a big mistake.Faculty when not instructing courses are still very involved in research and in service and even working with students.Since returning from Europe where I spent two glorious months as a Visiting Professor at the University of Gothenburg in Sweden, and also traveling and speaking at conferences in Sicily and Greece,  I have been busy working with my doctoral students.

    I wanted to analyze my tweets, so I did a little programming with the twitteR package on R, which helped me download my last 781 tweets or so (about 10% of my tweets) by calling the twitter API. Here is a wordcloud of the things I tweet about with a few common words like “the” and “that” removed. It looks like I spend a lot of time tweeting about #orms and Wisconsin to @jefflinderoth! A wordcloud of things I tweet about.   My 12 most favorited and/or retweeted tweets (of the last 781): Physicists on CS: "Programming, what if it's all just a fad?"…
  • engineering achievements of the 20th century

    Yesterday, I blogged about NAE grand challenges and how operations research can contribute to those grand challenges. You may find the list of 20th century engineering achievements interesting. The NAE’s full list of engineering achievements with an explanation for each item, can be found at www.greatachievements.org. Here is the brief list courtesy of the NAE publication The Bridge. The list is ordered according to importance. Electrification-Vast networks of electricity provide power for the developed world. Automobile-Revolutionary manufacturing practices made cars more reliable…
  • engineering grand challenges that operations research can help solve

    9 Jun 2014 | 12:12 pm
    In May, the report Operations Research – A Catalyst for Engineering Grand Challenges was released to the National Science Foundation [grant info here]. The report outlines operations research grand challenges for the next century, and they reflect the National Academy of Engineering’s list of grand challenges [Link]. This committee worked on a project funded by the NSF, and it was a great idea for highlighting the importance of operations research in relation to other STEM fields with regard to solving important societal problems as well as for prioritizing directions for our…

    A new report by the  President’s Council of Advisors on Science and Technology (PCAST) is all about how health care needs systems engineering solutions [Press release here]. The report entitled Better Health Care and Lower Costs: Accelerating Improvement through Systems Engineering outlines the various ways in which industrial and systems engineering can help. Several OR methods and tools are listed in the report, including operations management, queuing theory, simulation, supply-chain management. Rising healthcare costs are the motivation for this report. The United States spends more…

  • Competing on Quality and Supply Chain Networks

    25 Jul 2014 | 12:42 pm
    Quality was recognized already by Feigenbaum in 1982 as the single most important force leading to the economic growth of companies in international markets. Also, Buzzell and Gale in 1987 in their book, The PIMS Principles: Linking Strategy to Performance, recognized that, in the long run, quality is the most important factor affecting  business unit's performance and competitiveness relative to the quality levels of its competitors.So, why are we seeing so many examples of quality failures?Recent shocking examples have included  revelations, as reported by Bloomberg News, that…
  • Thanks to the National Science Foundation for Great Research Experiences for Undergraduates (REU) Program

    22 Jul 2014 | 7:47 am
    I returned around 1AM from Colorado where I had spent a few days visiting my daughter who is taking part in a 10 week National Science Foundation (NSF) Research Experiences for Undergraduates (REU) program at the University of Colorado Boulder.This was my first time in Boulder and I loved the vibe there, the natural beauty, the friendliness of the people, and, of course, the University of Colorado. I had been to Colorado multiple times for both conferences and visiting relatives but this was my first time in Boulder. The specific project that my daughter, Alexandra, is working on is:…

  • Soccer Won - the 2014 World Cup

    After Germany beat Argentina in the 2014 FIFA World Cup final today with Germany being crowned the champion of this monthlong competition in which 32 countries competed with their soccer teams, I took a walk.I needed to process this World Cup, which I think was the best ever in terms of the drama, athleticism, surprises, and outcome. I have written two previous posts on this World Cup.Seeing Gotze score with an amazing goal for Germany with the result that Germany won 1-0 against Argentina in overtime was quite special. The ball he bounced off his chest and then kicked it into the net.During…

  • Balancing today’s decisions against tomorrow’s conditions

    30 May 2014 | 11:15 am
    As organisations move up Tom Davenports’ analytics maturity curve, they encounter new challenges in using the insights from data analysis and optimisation models.  Today, the majority of organisations use descriptive analytics to create insights on what has happened. Also the use of diagnostic analytics to understand why things have happened is becoming more common. Moving up the curve towards predictive and prescriptive analytics is more difficult and requires the development of more advanced analytical capabilities. Gartner surveys indicate that about 13% of the companies are using…
  • The future of logistics lies in Analytics

    30 Mar 2014 | 2:40 am
    In a world in which everything and everyone is connected, in which the amount of data generated is growing faster every day and in which lifecycles of products become shorter and shorter, the need to be able to make smarter decisions is rising fast. Maybe in logistics this need is felt the most as logistics is vital in every supply chain. It requires the logistics manager to be well equipped for making though decisions. It’s my strong belief that access to data analysis, predictive and prescriptive analytics will become crucial for every manager, for the logistics manager in particular. For…
  • Intuition vs Analysis

    28 Feb 2014 | 1:54 pm
    Last week the acquisition of WhatsApp by Facebook was breaking news, a typical Mergers and Acquisitions decision. These types of decisions are one of a kind, need to be made in secrecy and at high speed as they can have huge impact on shareholder value. Many executives would argue that in these situations their intuition and experience is what makes the difference.  In their opinion, analysis would take too much time, moreover mathematical models can’t take into account the forces that either make or break the success of such a decision. They believe that intuition is…
  • The analytical crime watch; why your 13-year-old shouldn’t have a high-end mobile phone

    9 Jan 2014 | 1:34 am
    As an inhabitant of the metropolitan area of Rotterdam I am always curious to know how the city is doing, especially with respect to community safety. In Rotterdam community safety has improved in the past 12 years. Among other things, the number of incidents has gone down significantly and the resolution rates for high impact crime (Burglary, Street robbery and Robbery) have never been higher. Reasons for this decline are better deployment of the police force, the introduction of city guards and city marines (officials, appointed to improve tough safety problems in a certain part of the…
