“…Reported work involves assigning referees to fixed schedules. Gil‐Lafuente () suggests using a weekly referee appointment system that combines expert judgement of referees and solving an assignment problem based on these judgements. Dinitz and Stinson () assign referees to tournament schedules by using room squares from combinatorial designs.…”

Assignment decisions of referees to football (soccer) games are highly debated in sports media. Referee assignments are typically done on a weekly basis as the league progresses. However, this practice ignores important workload constraints on referees. Moreover, referees' skill levels should also be considered in determining their assignments. In this article, we first give a mixed integer linear program formulation for the problem of simultaneously generating a game schedule and assigning main referees to games by incorporating specific rules in the Turkish league. We also approach this problem using a genetic algorithm (GA) because of the computational difficulties in solving the problem. In the GA solution pool, we suggest using templates for referee assignments that follow several referee-related workload constraints. We explain how these templates can be obtained by solving a mixed integer linear model prior to running the GA. The usage of these templates for referee assignments is conceptually similar to using a basic match schedule for game scheduling such as the one used in the Turkish Football League. We use the Turkish Football League fixtures for 2010-2013 as a case study. Experiments with the GA using real-world data show a rather modest performance in terms of computation time and objective function value. Our numerical results indicate that the problem is extremely hard to solve.

This paper reviews about 50 years of activity in OR as applied to sports. After some history and an overview, including discussions of what we mean by sport and what we mean by OR, four themes are presented: tactics and strategy, scheduling, forecasting and 'other'. Within each theme many papers are discussed, showing the wide range of methods used and sports analysed. The issue is then raised of who our clients are and who they ought to be-it is suggested that not nearly enough is done for amateur sport. The paper ends with a conclusion and speculations about the next 50 years.
