poolautomaatidena
Poolautomaatidena is a term used in formal methods and computer science to describe a class of automata that model a shared pool of identical resources within a system. In a pool automaton, the state comprises two components: a control state and a resource level indicating how many tokens are currently available. Transitions may consume a resource token when a task starts or release a token when it finishes; some transitions may proceed without touching the pool. The model captures constraints such as not more than a fixed number of tasks running simultaneously and the requirement that a task cannot start if no resource is available.
Formal model: A pool automaton is a finite-state machine augmented with a finite resource counter bounded by
Relation to other models: Pool automata are related to labeled transition systems with resource tokens and
Applications: They appear in the specification and verification of resource management in software systems, such as
Example: A pool of three workers shared by tasks A, B, and C can be modeled so
Limitations: The abstraction omits scheduling policies, fairness guarantees, and timing information; practical systems may require richer
