In 2013 the first President’s Lifetime Achievement Award was presented to Prof David Ryan. The President’s Lifetime Achievement Award is in recognition of contributions made throughout the recipient’s career to both the ORSNZ and Operations Research in New Zealand and internationally.
|To honour the considerable contributions of Emeritus Professor Hans Daellenbach to Operations Research/Management Science (OR/MS) in New Zealand, the ORSNZ established the ORSNZ Hans Daellenbach Prize in 2001. Professor Daellenbach’s contributions reflect his belief that the best work in OR/MS combines strong innovative methodology with practical impact. The Daellenbach Prize will be awarded for such a body of work that has made a significant contribution and received international recognition. More details…
You can read more about Hans in the March 1999 Newsletter, and peruse one of his articles in the Jan 1996 Newsletter.

ORSNZ Visiting Lecturers
Call for Nominations: The ORSNZ invites nominations for ORSNZ honorary visiting lecturers to visit New Zealand between September and June each year. Each visiting lecturer is invited to give a talk on some topic likely to be of general interest to ORSNZ members at three or more of Auckland, Hamilton, Wellington, and Christchurch. Each visiting lecturer will be invited to write a guest editorial for the society newsletter. The ORSNZ contributes to the costs up to a maximum of $1000 plus GST (if any) per visitor. Each candidate must be nominated by a current member of ORSNZ, “the champion”. The nomination must include the CV of the nominated visiting lecturer, the date and location of the hosts of the visit, the name of the champion and an undertaking by the champion to coordinate a visit by the nominee to three or more of the above named centres. Enquiries concerning, or nominations for, lectureships should be sent to president@orsnz… The closing date for nominations is the end of April.
Once nominations have been received, the President will consult Council before forming a subcommittee to review the nominations. The subcommittee is to determine the options that are to be presented to Council. Multiple visiting lecturers in any one year are permissible if the circumstances permit.
- The Young Practitioner Prize (YPP) is open to all presenters at the annual ORSNZ conference who are within 5 years of graduation on the first day of presentations at the conference. YPP entrants must clearly identify themselves to the conference organisers by any deadline specified in the call for papers or on the conference website, when submitting their abstract and their paper, and when registering.
- YPP entrants will present their work in a talk of typically 15 to 20 minutes duration, with approximately 5 minutes for questions. (The exact figures are determined by the conference organizer to fit the conference schedule.) The presentation length will be strictly enforced.
- YPP entrants must submit a paper to the conference organisers that meets the requirements for inclusion in the conference proceedings. Except in exceptional circumstances, this paper will be published in the proceedings.
- Supervisors of YPP entrants are normally expected to appear as an author if they have contributed to the ideas or implementation described in the paper. Supervisors may not take part in the presentation of the work.
- In addition to the submitted paper, YPP entrants must submit a cover sheet (see YPPcoversheet.doc or YPPcoversheet.pdf) detailing:
- the starting point of the project (including existing software),
- the entrants’ contributions to the work (clearly distinguishing this from the supervisor’s contributions) and
- whether they are an industrial practitioner, or a PhD, Masters, or undergraduate student, and the time that they allocated to the project (e.g. 1/8th of an academic year, or 2 years of a PhD program, or 5 years working in industry).
This completed signed form should be brought to the conference and submitted during registration. This cover sheet is to be signed by the YPP entrant’s academic or commercial supervisor(s) (or the entrant themselves if no such supervisor exists).
- The ORSNZ will award up to four YPP prizes at each conference from a total prize pool of up to $1000 for the judges to distribute between winners as they see fit. Not all prizes will be awarded if there are insufficient entrants of a satisfactory standard.
- The judges will take into consideration the quality of both the entry’s written paper and their oral presentation. Guidelines that will be used to assess entries include originality, initiative taken, difficulty of topic, the amount of time allocated to the project, and a broader recognition of the context of the project such as the assumptions made, limitations, alternative views, innovation, potential application, and future work.
- Typically three prizes of values $500, $300 and $200 have been awarded.
- Multiple prizes have been awarded to the same person over several years.
- In 2006, the judging committee explicitly distinguished entries by PhD students and industrial practitioners from entries by Masters/Honours and undergraduate students.
- In past conferences, we have had talk lengths of: 2007:15+5; 2006:18 in total; 2005: 15+5; 2004: 20+2.5

John A. George (JAG) Memorial Prize
This prize is awarded annually for the best application of OR for improving lives.
“How does the project contribute to improving the quality of people’s lives, particularly those who may otherwise be vulnerable or disadvantaged, now, or in the future?”
|2018||Haddon Smith, Thomas Graham-Murdoch, Richard Clarke, Naresh Singhal, Alys Clarke, Vinod Suresh, Andrew Mason, and Stephen Waite (1st place)
Determining effective placement strategies for denitrifying bioreactors in New Zealand river systems
Jesse Prendergast, Andrea Raith, and Andrew Mason (2nd place)
Simulating First and Last Mile Transport in Auckland
“The John George Memorial prize was established to encourage researchers to think about the implications of their work in terms of improving the lives of people, particularly those who might otherwise be disadvantaged or excluded. It was always intended that the award could apply to cases where benefits were delivered directly to individuals, or indirectly by improving the environment within which communities must live.The paper delivered by Haddon Smith (with due acknowledgement to student co-author Thomas Graham-Murdoch and various supervisors) on Determining effective placement strategies for denitrifying bioreactors in New Zealand river systems, aligned perfectly with those objectives. We loved the way this project brought researchers from different disciplines together to address a major public issue of the day. And we were impressed by the way the authors applied several alternative OR techniques to real-life large scale catchments, and the broadly applicable insights they were able to infer from their detailed analysis.We also very much liked Jesse Prendergast’s paper on Simulating Transport-as-a-Service for First- and Last-Mile Transport in Auckland. This kind of service will be of increasing relevance, in terms of reducing energy consumption, greenhouse gas emissions and congestion, but also as a means of making realistically priced transport options more accessible to those unable to drive cars.We would like to commend all three contestants, and their supervisors, who all made positive contributions in their own way, and to specially thank Orbit Systems for sponsoring this year’s awards.”Grant Read, Vicky Mabin and Bob Cavana, JA George Judges, 2018

Energy Centre Prizes in
‘Energy and Resources’ and ‘Transportation’
The Energy and Resources Prize and the Transportation Prize are both open to all presenters at the ORSNZ conference who are under 30 years of age on the first day of presentations at the conference. Eligible entrants are those who have submitted a paper to the conference organizers that meets the requirements for inclusion in the conference proceedings. In the case that the paper has multiple authors, all authors must be under 30 years of age on the first day of presentations at the conference. (Any number of the authors may partake in the presentation.) In the case of joint authorship, the award is to all the authors as opposed to an individual.
The University of Auckland Energy Centre will award up to 1 prize in each of the Energy and Resource as well as Transportation categories at each conference from a total prize pool of up to $1000 for the judges to distribute between winners as they see fit. Not all prizes need be awarded if there are insufficient entrants of a satisfactory standard. The judges will take into consideration the quality of both the entry’s written paper and their oral presentation. Guidelines that will be used to assess entries include originality, initiative taken, difficulty of topic, the level of the project (e.g. developed as a masters vs PhD work) and a broader recognition of the context of the project such as the assumptions made, limitations, alternative views, innovation, potential application, and future work.
The Energy Centre is part of the Business School at the University of Auckland
These prizes were first offered in 2010.

12 November 2007: Institute for Operations Research and the Management Sciences (INFORMS) Fellowship for Professor David Ryan Professor David Ryan has become the second person in the southern hemisphere to be inducted as a Fellow of the Institute for Operations Research and the Management Sciences (INFORMS). INFORMS is the world’s largest professional organisation in Operations Research. It has awarded a total of 249 Fellowships, but only 12 of those, including Professor Ryan’s, have gone to people outside of the United States. Professor Ryan received his award at a ceremony during the INFORMS Annual Meeting in Seattle last Monday, 5 November. The Fellow Award is reserved for distinguished individuals who have demonstrated outstanding and exceptional accomplishments and experience in operations research and the management sciences.
Professor Ryan is Deputy Dean of the Faculty of Engineering and a Professor in the Department of Engineering Science. A leading authority on Operations Research in New Zealand, his research is concerned with mathematical programming and optimization theory, in particular scheduling, timetabling and combinatorial optimization problems. Professor Ryan was evaluated on the quality of his research, practice, management, education and service before receiving the INFORMS award. He is also a Fellow of the Royal Society of New Zealand (2003).
INFORMS Teaching Award 2003: In 2003, David was awarded the INFORMS Prize for the Teaching or OR/MS pracitioners. See “Ryan Educates, Inspires OR/MS Practioners” (local copy), OR/MS Today August 2003.
|16 November 2007: Michael Saunders, FSRNZ
On behalf of the members, the Operational Research Society of NZ wishes to congratulate long-standing society member Michael Saunders on being elected an Honorary Fellow of the Royal Society of NZ.Michael Saunders, a Research Professor in the Department of Management Science and Engineering at Stanford University, is a world expert in the development of mathematical optimisation software, for solving decision problems in large interconnected systems.Professor Saunders began his work in this field while working for the DSIR in the 1970s, producing (in joint work with fellow New Zealander Bruce Murtagh) the MINOS system, which is now one of the best known optimisation packages worldwide, used by economists, engineers, physicists, and operations researchers. In more recent years he has developed a collection of optimisation tools (NPSOL, SNOPT, QPOPT, LSSOL) tailored to solve problems having certain structural features, with wide application in the engineering and aerospace communities. In particular, NPSOL is a key ingredient in the mesh-fitting routines used by the Auckland Bioengineering Institute, and in the optimising yacht velocity prediction program used by Team New Zealand in the successful 1995 America’s Cup challenge.He is a member of the International Scientific Advisory Board of the New Zealand Institute of Mathematics and its Applications, and is a leading supporter of the Operational Research Society of New Zealand, and a mentor for its members. His published work is very highly cited, and in 1985 he was awarded the inaugural Beale-Orchard Hays prize by the Mathematical Programming Society for his contributions to computational optimisation.
