This paper analyzes stochastic performance of a distributed global activity, composed of sub-activities sequenced serially, probabilistically, or concurrently. We provide general formulas with which we calculate the per-formance of a composite activity based on the performance of the constituent sub-activities and the control structure. To do this, we model each sub-activity as a Partially Ordered Specification (POS), where each sub-activity is character-ized by independent input events, dependent output events and the stochastic minimum delays between these events. This technique allows two or more sub-activities to be combined hierarchically. Proofs of correctness for these formu-las are given and a simple example …
