Professor Mike Wright

Emeritus Professor

Research Interests

The development and analysis of metaheuristic methods and their implementation to practical problems including sports timetabling and employee scheduling.

The analysis of tactics in sports, especially football and cricket.

Profile

Born in 1953 in Warwickshire. Worked for British Rail in York and London before serendipitously landing in Lancaster. Married with three children and two grandchildren so far. Lives just outside Lancaster, sings, plays cricket, tennis, indoor hockey and golf, walks, travels, listens to music, goes to the theatre. Actively supports Lancaster City Football Club in a vaguely patriotic though largely masochistic fashion.

Current Teaching

Strategic Management Simulation; Introduction to Project and Event Management; supervision of placements, projects and dissertations. Recently also Heuristics, Optimisation, Introduction to OR, Introductory Statistics, Introduction to Business Analytics, Project Management Skills, OR and its Context.

Thesis Outline

The thesis includes nine published papers, all on the subject of Neighbourhood Search metaheuristic techniques for solving combinatorial optimization problems with more than one type of objective. The first five are very application-oriented. The first of these five concerns a real type of problem, but does not report a specific implementation of the application. However, the next four papers go further and describe highly complex problems which have arisen in practice and the approaches and techniques used by the author to solve them. The last four papers complement these by exploring the development of the techniques, reporting the results of experiments into their application and extension. Thus the research demonstrates a progress from the particular to the general. Specific approaches were found to work well in particular situations; this provided a spur to discover whether these techniques could be developed and used successfully in other circumstances.

One of the most useful results of this research is the demonstration of how metaheuristic approaches can be used in practice to solve large complex real problems. Careful definition of seemingly ill-defined notions and the intelligent development and application of techniques have combined to produce methods which give highly satisfactory solutions to such problems. The main theoretical result from this research is the development of an approach called "Subcost-Guided Search", which includes "Subcost-Guided Simulated Annealing". Papers 2, 4 and 5 show its application for real problems, while papers 8 and 9 discuss experimental results and different ways of applying the idea.

Other useful contributions are also presented. For example, the related issues of problem formulation, neighbourhood definition and the nature of search space are highlighted in several of the papers. The proposed measurement and effect of problem complexity are also discussed.

The papers were all strictly refereed and published in high-quality journals or books.
