其他摘要：The methodology used by business organizations to distribute their budget and select which projects - among all potential candidates - must be carried out to satisfy their needs has changed considerably since the organizations started to support their selection decisions in a mathematical model. The purpose of this paper is to provide a descriptive and comparative analysis of the different techniques used over time; we also present a small example to clarify their function, and thereby we show both its advantages and disadvantages. These drawbacks were the principal cause of their evolution towards more completed and sophisticated techniques. This study highlights two aspects: first, the evolution of the organizations has changed the problem of selection from project selection to portfolio selection and scheduling, and secondly, the problem is not solved yet, and we need a global model to resolve whatever problem of project portfolio scheduling and selection.
