Correctness of realizations of levels of abstraction in Operating Systems,of the processors, and (2) properties of the scheduling program. The hierarchy of the system is taken into account to proceed step by step to the proofs of the realization of the last level and, consequently, of the whole system. Advantages and inconveniences of the method are discussed.

A new approach to avoidance of system deadlocks,o, an algorithm that tests how many resources can safely be allocated is easily found and the method makes it possible to attach a cost factor to resource allocation depending on the demand and the allocation test.

Correctness of realizations of levels of abstraction in Operating Systems, any two adjacent levels L (low) and H (high), the processes of level L are seen as (virtual) processors realizing the processes of level H. A Scheduling program is assumed to implement the realization of level H by level L. Means of defining properties of this realization are studied, together with
