History of the Award

At the ASOR National council meeting held on June 5, 1994, it was agreed that ASOR will establish a national prize for outstanding contribution in OR. The award may be presented for a major development in theory, application of OR in an industry or for any other reason considered worthy by the ASOR National Council. The award can be given to an individual or a group of persons, or to an organization. The award will be presented at the National conference. However, ASOR National Council members will not be considered for the award during their term as council members. The applicant must have significantly contributed to the growth/development of OR in theory or applications.

Award Criteria

The criteria for the award will be considered satisfied if the applicant's claim is judged by the committee satisfying one or more of the following statements:

  • the application of OR has resulted (or will result) in substantial benefits in the organization
  • the applicant has demonstrated successful and consistent promotion of OR in industry and/or the wider community.
  • the theory developed by the applicant opens a possible field for research.
  • the work of the applicant will have an international impact in the OR community, or its users. This can be in the form of a software, a text book, or a research monograph. Supervision of a substantial number of students for a higher degree by research in OR (Master or Doctorate) will also be a possible consideration to satisfy the requirements for the ASOR award.

In all cases supporting evidence will be required. The latter may be in the form of publications or a letter from the Head of the organization that has been benefited by the OR application. If the claim is for savings, it should be substantiated.

It is not possible to develop criteria common to all possible applications. However, each application will be reviewed by the evaluation committee and relevant additional information in terms of referees reports and management evaluations will be sought as appropriate. Theory or an application of OR which draws the national/international attention is considered worthy of the award. In all other cases, it is desirable to develop some quantitative measures which may be considered by the society as worthy of the ASOR award. For this purpose the following possible scenarios are suggested which may be reviewed by the council from time to time.

  1. For claim based on an application a measure of success can be:
    1. by resulting savings
    2. by impact on the performance of an organization
  2. For successful and consistent promotion of OR in Industry and/or Commerce:
    1. record of performance
    2. support of the relevant organization
  3. For claim based on the theory it may be measured in the usual way such as:
    1. publications in OR or related journals and their impact
    2. supervision which resulted in a research degree award on an OR topic, to at least five students who went on to successful careers
    3. an OR text book or a major software used in at least 5 educational/ commercial institutions.
    4. research monographs - which describes material from journals in a usable form by the wider community.
    5. some combination of the above deemed sufficient by the committee.

Nomination Format and Key Dates

A nomination for the Ren Potts Medal is a document of one to four pages describing the case for the nomination and providing and/or citing evidence supporting this case. The selection panel will consider each case submitted.

Nominations for 2021 are now closed; a call for nominations for 2022 will be issued in about May 2022.

John Hearne - recipient of the Ren Potts award in 2020

John Hearne's involvement and contributions to OR involve more than three decades. During this time he has made contributions to OR in several ways. These include supervision of research students, publications, and service to OR. Most of the research of the 21 PhD students he has successfully supervised to completion were in the area of OR and the majority of these are still active in this field. At RMIT, John Introduced Australia's first Masters program in Analytics. Current enrolments exceed 400 students. John has contributed to OR theory and applications around Sensitivity Analysis and Model Simplification,  OR and wildlife,  OR and water management, and OR and Wildfire. In the OR and wildlife area, key examples of his contributions are in developing translocation strategies for saving the black rhino, optimal strategies for converting cattle farms to wildlife ranches, strategies for making the consumptive use of wildlife viable in Australia, and methods for natural reserve planning and re-planning under climate change.

Kate Smith-Miles - recipient of the Ren Potts award in 2019

Over the last 25 years, Kate Smith-Miles has developed a reputation as one of Australia’s most exciting operations researchers, contributing new methods and tools, and applying them successfully to a broad range of industry and interdisciplinary problems. Highlighting just a few of her many research contributions, she has developed:

  • powerful new methods for solving combinatorial optimisation problems by exploiting chaotic dynamics and self-organisation;
  • novel formulations of practical industrial optimisation problems (in particular via seven ARC Linkage grants) so they can be solved using traditional methods, as well as developing new algorithms tailored to these industry problems;
  • new methods for tackling black-box optimisation problems, where analytical methods are not available, and experimental data is expensive, limited and contains many sources of uncertainty;
  • new ways of integrating machine learning methods with optimisation to support intelligent optimisation methods that are responsive to dynamic conditions;
  • a powerful new methodology known as Instance Space Analysis that offers a paradigm shift in the way algorithms, including optimisation algorithms, are tested to gain much needed insights into their strengths and weaknesses.

Beyond these contributions from an operations research perspective, she has also developed new mathematical approaches to tackle a range of other problems, including novel multilinear algebra and tensor analysis techniques achieving world-leading results in the field of image processing; mathematical modelling of stem-cell decision making; rare event detection in noisy time series; and many other topics. Kate has an extensive network of collaborators, both mathematical and in the broader academic community. She has developed a diverse toolkit of mathematical techniques from operations research and mathematical modelling, and the language and communication skills needed to collaborate with researchers and industry partners on problems arising in multiple different fields. This breadth has produced a tremendous portfolio of over 250 refereed scientific publications in total, many of which are in optimisation, highlighting the value of operations research, and mathematics more generally, in addressing significant industry and interdisciplinary challenges. She has supervised 25 PhD students to completion, and received over $12 million in competitive research funding. She has papers that have been published in top journals and which have made an impact on operations research and other disciplines. She has 23 papers that have attracted more than 100 citations each.

Peter Taylor - recipient of the Ren Potts award in 2017

Peter Taylor received a BSc(Hons) and a PhD in Applied Mathematics from the University of Adelaide in 1980 and 1987 respectively. In between, he spent time working for the Australian Public Service in Canberra. After periods at the Universities of Western Australia and Adelaide, he moved at the beginning of 2002 to the University of Melbourne, where he took up a position as the inaugural Professor of Operations Research. He was Head of the Department of Mathematics and Statistics from 2005 until 2010.

Peter's research interests lie in the fields of stochastic modelling and applied probability, with particular emphasis on applications in telecommunications, biological modelling, healthcare, economics and disaster management. Recently he has become interested in the interaction of stochastic modelling with optimisation and optimal control under conditions of uncertainty and with blockchain technology. He is regularly invited to present plenary papers at international conferences. He has also acted on organising and program committees for many conferences.

Peter was the Secretary of the South Australian Chapter of ASOR in 1983 and 1984, President in 1985 and 1986, and a Committee Member in 1987 and 1988. In August 1985, while still a PhD student, he was the Secretary of the Seventh National Conference of ASOR, held in Adelaide. His greatest memory of this time was having the honour of hosting the plenary lecturer George Danzig for a large part of the conference. Peter has gone on to hold other significant leadership positions in the Australian mathematical science community: Chair of ANZIAM from February 2006 to February 2008, President of the Australian Mathematical Society from 2010 to 2012 and a member of the Australian Academy of Science's National Committee for the Mathematical Sciences from 2007 to 2015.
