This study uses a multi-output multi-input Data Efficiency Analysis (DEA) to estimate the performance of all thirty-two participated football teams in the UEFA Champions League (CL) tournament 2005-06. The estimates are based on official match statistics from all 125 matches.

This paper examines the effects of a win bonus, effort, costs and team size, on the demand for talented players, the win percentage and the profits of small and big teams. Teams play a Cournot game, under the following objective functions: (i) teams maximize profits, (ii) teams maximize win...

This paper attempts to find the optimal formation of three midfielders and three forward football players on ground, using the classic Quadratic Assignment Problem or Facility Layout problem. Players are treated as “machines”, their positions as locations, and the flow of materials between...

Official match-play statistics from the Champions League tournament between 2001-02 and 2006-07 are used to estimate the impact of various variables on the performance of the teams, measured by goal difference.

We formulate a non-linear integer programming model and use plausible parameters to examine: (i) the effects of wage differences between Super- and Normal- players in the performance of four teams which participate in the UEFA CL group matches; (ii) whether the expected qualification bonus...

This paper investigates if the value of the Swedish krona (SEK) against the US dollar ($) and the Euro (€) can be explained by some standard theories and fundamentals, such as the purchasing power parity, the interest rate parity, the debt-ratio and the trade balance ratio, using monthly data...

There are several methods to convert fuzzy or stochastic LP to conventional LP models. In this simple paper we evaluate the effectiveness of three proposed methods, using a numerical example from a pure factors portfolio.
