Abstract:
A method for estimation of time, requiered for external events processing by distributed program applications is presented. It is shown that feasibility of such applications may depend on variation of task execution time and message delivery time. The influence of this variation shall be taken into account during feasibility checking for task chain, that shall be activating due to processing of separate external event.
Keywords:real-time systems, models of multitask software systems, distributed computations, dynamic correctness of software applications.
