Specification of schedulers with algebraic specification techniques
- 120 Downloads
The specification of a class of single resource schedulers is presented. A class of these schedulers is regarded as a parameterized data type whose formal parameter is a scheduling strategy. The specification is given by using the concept of parameterization in algebraic techniques. The specification of each scheduler instance can be directly obtained only by replacing the formal parameter with a concrete scheduling strategy. The assignment of an actual parameter to a formal parameter is given by a mechanism called extended parameter morphisms. This specification technique is applicable to many other objects.
