Management of Human Factor is a key point in the competitiveness of companies with a large production capacity based on operator. The efficient use and management of these resources is essential to meet the company's performance objectives. In this article we will present, first, the research work on the problem of resource allocation under constraints, more precisely the work which took into account the impact of the integration of skills, preferences and the Polyvalence or the joint integration of these constraints in the problems linked to the allocation of human resources. Second, the works that deals with the phenomenon of absenteeism. Finally, we will propose a methodological approach allowing the resolution of the problem of allocation of human resources under absenteeism constraints for industrial Activities. Resource allocation, Skills, Preferences, Polyvalence, Absenteeism, AHP. I-INTRODUCTION Management of Human Factor is a new topic in Morocco not only micro-economically but also macroeconomically and whose impact is significant on the performance of companies, and a need as companies face several obstacles in the industrial world .In this regard. Companies need to be flexible and have an effective management mode of their human resources to be competitive. The multiple researches [1]-[2]-[3] carried out on the problem of allocation of human resources prove more of the importance given to the management of human capital. This research is interested in integration, competence, preference, or polyvalence, or the combined integration of competence and preference in the issue of allocation candidates to workstations. To our best knowledge, no author has studied the integration of the three constraints simultaneously for the problems related to the problem of allocation of resources. From our research, we have noticed that the combined integration of the three constraints has never been treated. In Resource allocation issues, the existing work is essentially about the integration of the two Criteria, namely competence and preference, competence and polyvalence. In the article [Sabar, 2008] [4], the problem of allocation operators in an assembly line has been treated by proposing a modeling of the problem of flexible assignment of the operators on an assembly line while holding account of the two constraints, preferences and skills of the operators. In 2007, [Gutjahr and Rauner] [5] studied the construction of a schedule that meets both the preferences of the nurses and the needs of each shift in terms of the number of nurses of all types, grades, [ Peters and Zelewski] [6], tried to solve the constraint assignment problem (skills and preferences) using the AHP method. [Raoudha, 2011] [7] Was interested in proving a correspondence between the demands of tasks and the skills acquired by human resources without eliminating the constraint preferences. To do this, he used an algorithm based on the combination of the benefits of the bee algorithm and the immune system to solve the problem. [Kharbach, 2016] [8] I...
