title = "Enacting declarative languages using LTL: Avoiding errors and improving performance",
abstract = "In our earlier work we proposed using the declarative language DecSerFlow for modeling, analysis and enactment of processes in autonomous web services. DecSerFlow uses constraints specified with Linear Temporal Logic (LTL) to implicitly define possible executions of a model: any execution that satisfies all constraints is possible. Hence, a finite representation of all possible executions is retrieved as an automaton generated from LTL-based constraints. Standard model-checking algorithms for creating B{\"u}chi automata from LTL formulas are not applicable because of the requirements posed by the proper execution of DecSerFlow (and LTL-based process engines). On the one hand, LTL handles infinite words where each element of the word can refer to zero or more propositions. On the other hand, each execution of a DecSerFlow model is a finite sequence of single events. In this paper we adopt an existing approach to finite-word semantics of LTL and propose the modifications of LTL and automata generation algorithm needed to handle occurrences of single events. Besides eliminating errors caused by the {\textquoteleft}multiple properties - single events{\textquoteright} mismatch, the proposed adjustments also improve the performance of the automata generation algorithms dramatically.",
