  • PANORAMA SOCIOECONÓMICO AÑO 24, N° 33, p. 66-74 (Julio - Diciembre 2006) INVESTIGACIÓN / RESEARCHMathematical Modelling of Human Motivation: A VectorHypothesisModelación matemática de la motivación humana: una hipótesis vectorialIvan Kotlíarov^^C.Sc. (in Econometrics), B.Sc. (in Human Resource Management), Saint-Petersburg University of Economics and Engineering, Russia.E-mail: lrpg@mail.ru ABSTRACT. The present article gives a list of axioms needed for building up a mathennatical theory of human motivation. A mathematical model of labour motivation is proposed. Motivation is represented as a resulting vector of partial motivation generated by specific groups of needs. Vrooms model is included in the proposed model as Instant motivation. Theoretical correlations between the quantity of funds dedicated to motivate employees and the intensity of motivation factors and between the level of motivation and the level of productivity are proposed. Key words: Motivation, vector, needs. RESUMEN. Este artículo presenta un conjunto de axiomas necesarios para construir una teoria matemática sobre la motivación humana. Se propone un modelo matemático de moti- vación del trabajo. La motivación es representada como un vector resultante de la motivación parcial generada por grupos específicos de necesidades. En el modelo propuesto se incluye el modelo de Vroom como motivación instantánea. Se proponen las correlaciones teóricas entre la cantidad de recursos dedicados para motivar a los empleados y la intensidad de los factores de motivación y entre el nivel de motivación y el nivel de productividad. Palabras clave: Motivación, vector, necesidades. (Recibido: 30 de agosto de 2006. Aceptado: 30 de octubre de 2006)66

It isOur understanding of the nature of human motivation logical to use these axioms as a basis for adid gradually improve over the years (we have now mathematical theory of work motivation (I omit themany more or less consistent theories giving adequate detailed overview of motivation theories in order todescriptions of motivation processes), but a good spare time; a good description from the managementsmathematical model of work motivation is not point of view can be found in [Mescon, Albert, Khedouriavailable. Actually the only example of mathematical 1992]; psychological overview is given in [Njin 2000]).approach towards this problem is Victor Vrooms These axioms are the following (it is worth mentioningmodel [Vroom 1995], but it is rather qualitative than that the complete set of axioms is given for the firstmathematical in the proper meaning of this word, as time; none of existing theories of human motivationit limits itself to only one formula: operates with this list, they just use - explicitly or implicitly - some of them): M = RBW where 1. Human beings have needs that they want to M - motivation; satisfy. Its a common place in most psychological R - employees expectations that his/her and marketing theories. efforts will lead to necessary results; 2. Human motivation (understood as a persons B - expectations that the results will lead to state that defines degree and orientation of activity the expected remuneration; of a person in a given situation) is determined by W - expected value of the remuneration. human needs. All content theories of human motivation include this stipulation as a basicAll other theories existing in this field: Maslows hypothesis, while process theories include ithierarchy of needs [Maslow 1970], Herzbergs two- implicitly (see above, for example, for Vroomsfactors theory [Herzberg, Mausner, Snyderman 1959], model: motivation depends on the value of theMcClelland model [McClelland 1961] - do not offer remuneration, but value of a good is a function ofany quantitative methods for modeling motivation, they its utility, that is, of its capacity to satisfy humanexplore the psychological aspect of motivation but do needs).not use mathematics at all. It is easy to conclude for the axioms 1 and 2 that the satisfied needs have no influence on humanIt is obvious that absence of mathematical tools in motivation. It is very important to remember thatthis field of human resources management is needs that are not actually satisfied, but whoseabsolutely unacceptable nowadays and I will try to fill satisfaction is perceived by a person asin this gap in the present paper. guaranteed (in other words, needs whose satisfaction is seen by a person as guaranteed to DEFINITIONS AND AXIOMS a such degree that he or she perceives them as satisfied, despite the fact that they actually areFirst of all, it is necessary to give a clear and precise not) do not have influence on human motivationdefinition of motivation. Motivation of a human being either. For example, in economically developedis a temporal and dynamic psychological state that countries (like EU), needs belonging to lowerdetermines his/her involvement in an action levels of Maslows pyramid generally have no[Motivation 7; Motivation 8]. Motivation is sometimes influence on human motivation [Mescon, Albert,referred to as process [Motivation 8] thus leading to Khedouri 1992] because of peoples confidenceconfusion between 2 aspects of this concept: in their present and future situation thanks tomotivation as the psychological state of a person who relatively high salaries, good social securityis doing something and motivation as a process of systems and powerful trade unions. However, anyencouraging a person to do something (the latter is of these low-level needs in any moment may bebetter referred to as motivating). Motivation will be actually unsatisfied.considered in this article as a state. 3. Human needs can be divided into separate moreA thorough analysis of motivation theories shows that or less homogenous groups, each one of these 67

I will refer to needs can be satisfied by specific goods, these groups of needs as to motivation factors. typical for this group only. It means that goods An indication to this axiom first appeared in (material, non-material or abstract) that satisfy content theories with their divisions of needs; needs from a certain group of needs cannot however, to the best of my knowledge, neither satisfy needs from other groups (need in this axiom, nor the concept of partial motivation security cannot be satisfied by a hamburger, have not been proposed before. creative needs cannot be satisfied by purchase4. In general, the number of groups of needs of trousers). I would like to highlight that this is influencing a persons behaviour in the moment t true in general - in some specific cases goods is superior to 0. Mathematically it can be can satisfy different needs. An obvious example expressed as follows: if N is the number of is money that can be used for purchase of separate groups of needs, N>0, and if n is the virtually all goods for all types of needs. A number of groups of needs determining an "Rolls-Royce" is not simply a car (that satisfies individuals behaviour in the moment t, then. transport needs) - it can also satisfy ones needs in prestige and luxury. But in general 0<n<N different needs are satisfied by different goods. We can conclude thereof that different needs This axiom has not been formulated explicitly make people act differently in order to achieve before, however some hints can be found in the different goals (we can see a clear connection literature. between the axiom 6 and the axiom 7). Indirect The axiom 4 leads us to the conclusion that the indications to this axiom can be found in the general (total) motivation is equal to 0 in only one literature. case: when all partial motivations are equal to 0, 8. Contributions of all groups of needs (motivation or, in other words, if one or several (k, k<n) partial factors) into total motivation are described by the motivations are equal to 0, the total motivation same mathematical functions (I could have said will nevertheless be different from 0. Mathematical instead that the psychological mechanism of corollary to this conclusion is that we cannot correlation between a need and the motivation is calculate total motivation multiplying partial the same for all types of needs). We can draw motivations. this conclusion from the fact that no motivation5. Every group of needs can be described by two theories - either content or process - supposes characteristics - intensity and importance. a specificity of any group of needs, motivation Intensity is the quantity of goods required to satisfy mechanisms are described the same way for all this need.

The general motivation directly depends on groups them, the theory will be over-simplistic or simply of needs (motivation factors) - that is, if the intensity incorrect. and/or the importance of a given group of needs is growing, the overall motivation will grow too.

Thus, resulting vector of these partial motivations - or, inlet us suppose that human needs are divided into N other words, the overall motivation is itself a vectorgroups - but not specifying what criteria we use to described by a motivation vector.
