The disclosure aims to solve the general problem of managing the system with multiple resources of different types. In particular, the disclosure is intended for the sharing of resources between multiple applications that can be executed on a computer platform for situations involving the addition of new resources that were not initially provided in order to achieve these objectives, conflicts are avoided between shared resources starting at the application, with access rights being allocated for each application, while an opening is maintained for the addition of new applications and resources. More specifically, according to this method for managing the resources of a computer system, that are shared between multiple applications, allocation rules are provided during the execution of the applications and the rules generate access rights for each application in relation to each shared resource in the form of successive steps. The steps are controlled for each shared resource by a specific control module and, with each command, a decision criteria module parameterization step checks the rule for allocating access rights, whereby the decision criteria can be shared between at least parts of the control modules.
