Programme and Venue

ILOG/ORSNZ WORKSHOP Using Optimization Software in Practice, Thursday 28 November

In conjunction with the ORSNZ annual conference, the ORSNZ and ILOG are pleased to announce a one-day tutorial workshop on optimization hosted by Dr Sanjay Saigal. Dr Saigal is the vice president and general manager of ILOG Direct, with responsibility for ILOG’s direct sales channel. He holds a doctorate in mathematical sciences from Rice University in Houston, and has over 10 years industrial experience in the development and delivery of decision-support software and consulting services.

The workshop will be held in the computer laboratory of the department of Engineering Science at the University of Auckland. Attendees will be expected to have had some previous exposure to optimization and Excel. The Workshop includes a hands-on introduction to OPL Studio, ILOG's modelling environment for mathematical and constraint programming.

Workshop Programme

  • Modeling approaches
  • LP/MIP - state of the art
  • Constraint programming for combinatorial search
  • Others - QP, NLP, MINLP, Stochastic, etc.
  • Products
  • Optimization engines (CPLEX, Solver, ...)
  • Modeling languages (AMPL, OPL, ...)
  • Embedding options and their trade-offs
  • Exploiting constraint programming
  • Scope and limitations
  • Role of search
  • Extensions to scheduling, dispatching and configuration
  • Commercial application development
  • Architecture
  • Data I/O
  • Visualization of large data-sets
  • Automating business logic
  • You can register for the workshop on the conference registration form, together with registration for the conference.

    Fees are NZ$ 150 for ORSNZ members, NZ$ 200 for non-mebers and NZ$ 50 for students.

    Conference Speakers

    The programme includes two plenary addresses by the following speakers:

    Decision-Support System Development Beyond Linear Programming

    Focusing primarily on developing decision-support systems (DSSs) based on traditional mathematical programming techniques - LP/MIP, for instance - has unnecessarily restricted industrial OR's scope of practice. In a sense, OR practice in the corporate sector remains a niche within a niche. We describe recent DSS trends that allow us to extend OR practice into areas hitherto deemed too complex for structured optimization (e.g., real-world supply-chain planning, configuration) or "not really OR" (e.g., policy automation). Our presentation is driven by quintessentially practical considerations - what do the consumers of OR need? What are their organizational constraints? What is the perceived value of our raison d'etre - optimality?

    Multiple Criteria Optimization in Portfolio Selection

    In finance there is the famous Markowitz formulation whose solution set is the efficient frontier in mean/standard deviation space. While textbook theory states that everyone has the same efficient frontier and faces the same equilibrium market portfolio, it is widely known that this is not exactly the case. People have different limits on the amount they wish to invest in a stock, on the degree they wish to engage in short selling, and on the number of securities they will tolerate in their portfolio. Commonly implemented as constraints in order to remain in 2-space, all of these limitations, as shown in the paper, have an extremely dramatic effect on the efficient frontier, to the extent that it would not make much sense to restrict the search for an improved theory of portfolio analysis. In particular, the limitations of short selling and the number of securities in a portfolio are probably more adequately modeled as criteria. Along with other concerns such as social responsibility and dividends, we are now, in the opinion of this author, most decidedly beyond mean/standard deviation space and in the realm of multiple objectives. With multiple objectives transforming the efficient frontier into an efficient surface, this paper discusses new approaches, new solution procedures, and new ways of rationalizing equilibrium in asset prices with a view toward developing a new more realistic multiple criteria based theory for portfolio selection.


    The conference proper will be held in Architecture (building 421), in rooms ALR1 and ALR3; see this map of the city campus. Architecture is most easily accessed by going through the Conference centre at 22 Symonds St (between Wellesley St East and Grafton Rd, on the Grafton Road side).

    Breakfast, morning tea, and afternoon tea will be served in the foyer and garden area outside these rooms. Lunches will be served in the Engineering staff common room, level 12, Building 401.

    The workshop venue will be the University of Auckland School of Engineering.
    The workshop tutorials will be held in the Engineering Science computer lab, room 515, Building 404.
    Breakfast, morning and afternoon tea, and lunches will be served in the Engineering staff common room, level 12, Building 401.

    Please refer to the map of the city campus (also available in PDF format). The main entrance of the School of Engineering is at 20 Symonds St (on this Wises map).

    Note that the University has no student parking; this is a recent change. We suggest you park in the Victoria Street car park (entered by turning left at the intersection of Victoria St East and Kitchener St) or the Kitchener street car park (on the left after entering from Wellesley St East), and the walking through Albert Park to Symonds St. See this map.


    Transpower Young Practitioner's Prize

    The Young Practitioners competition is open to authors under 25 years of age on 1 Jan 2002. Papers must be singly authored. More details are contained on the registration form. The Prize of NZ$ 1,000, sponsored by Transpower, is to be split between the author(s) of the best paper(s), according to the judges' discretion.

    Special Session on Group Decision Making

    The session is devoted to all problems connected with group decision making (i.e. when decision is made by more than two actors) such as modeling decision making process, voting techniques, power indices in both theoretical and practical aspects (EU, UN, parliaments on national and supranational levels). Perspective speakers are kindly requested to contact the session organiser Jacek Mercik at [email protected].

    Social Programme

    There will be a pre-conference gathering at 7 p.m. on 28 November, at Old Government House, University of Auckland. Old Government House is located between Princes and Symonds Streets and Waterloo Quadrant, see the map of the city campus (also available in PDF format) or this Wises map.

    The conference banquet will be held on the evening of 29 November at the Copthorne Hotel, Anzac Avenue, see this Wises Map.
