Choosing among dozens or hundreds of alternatives for those which shall compound the portfolio of projects of an organization and with such a priority, it is a complex multicriteria decision matter. This work has aimed mainly at proposing a management model of portfolio of projects, utilizing the method AHP (Analytic Hierarchy Process) and integer program being both integrated. It has also. It has also had as a purpose to validate and evaluate the importance and utility of that model on helping the decisionmaking related to the selection and prioritization of projects. Thus, such a model has been applied to select and prioritize the projects of an enterprise in the chemical sector, chosen as the unit of analysis. The different scenarios obtained from the decision-making model proposed were compared to the real scenario of the company. Since the author interacted in the enterprise decision-making not just as an observer, to carry out the study it was chosen the research-action method, for being the most adequate to the case. It could be noticed that the use of the model contributed first, to the strategic alignment of the projects permitting the exchange of knowledge between the enterprise representatives; secondly, it allows the simulation of strategic scenarios in real time and as well as the verification of the impact of the portfolio of projects being carried out; thirdly, it prioritizes the projects in a justifiable and structural like way through an established mathematical model; finally, it enables o allocate the resources based on priorities and it allows the introduction of a continuous improvement cycle in the enterprise decision-making process, once every step of the implementation of the model, definitions and decision-making criteria are validated. The use of the model has proven to be more efficacious than the enterprise real result in allocating the financial resources. The work also suggests further complementary studies.
