A New Tool In The Treatment For The Wider Information Provided By Experts For The Selection Of Players

Abstract

Up to now we have been seeking an optimum application of a series of techniques arising from multivalent logic to sports management, both in the selection of players for an individual or polyvalent function, as for assignment, grouping, etc., even creating new instruments (such as the maximum and minimum level index) which would allow us to adapt in a manner that was even more reliable to the always complex and unstable reality. In many cases, and in order not to incur in uncontrollable errors the expert was advised, in the event of doubt, to work with confidence intervals in stead of doing so with crisp numbers which, to a greater degree, allowed for limiting the uncertainty and doing calculations that ensured that we avoided errors in any of the estimates or valuations carried out. The results were satisfactory. Nevertheless, it is possible to approach a new question: that is, if the experts could see themselves as carrying out their valuations in a more meticulous way if possible (by providing several possibilities between a minimum and maximum), valuing, for example, by means of fuzzy numbers, would it be feasible to operate in order to find in the end, Hamming distances?. The answer is yes. In many manuals we have been provided with the techniques which allow us to calculate distances, on the one hand and operate with fuzzy numbers on the other, but to find distances between fuzzy sub-sets of a degree б (for example 2) is a challenge which we have allowed ourselves to tackle.
