“…We are also interested in "positive" patterns, which would allow us to lower the probabilistic bounds for nets matching these patterns, since our probabilistic bound can clearly be further lowered for some classes of nets. We also want to investigate the applicability of Bayesian methods for the log completeness problem APPENDIX In this final part we present a lemma and detailed derivation of (3), (11), (12) Note that we assume in an acyclic T-workflow net, choices of all the enabled transitions are made with equal probabilities. Therefore, a and b are simultaneously enabled if Z i (a, b) = {3, 4}, and one transition is chosen with probability 1 2 .…”

“…First, we focus on the probabilistic bounds for log completeness obtained using Algorithm 2 both with formula (8) and with formula (10). We generate structured Jackson nets [11], which form a subset of sound workflow nets. We generated 100 structured Jackson nets, each with 30 transitions.…”

“…In the scientific workflow community, workflow design issues have received comparatively little attention in the past, but their importance is now more fully emerging [4,10,15,13,18,19,1,35]. In this paper, we have presented VDAL, a scientific workflow modeling and design paradigm for data assembly lines that aims at minimizing the "shimantic web syndrome" [16], i.e., the proliferation of unnecessarily complex workflow designs that involve large numbers of shim actors and "messy wiring", thus obfuscating the scientific protocol that the workflow should capture in the first place.…”

Despite an increasing interest in scientific workflow technologies in recent years, workflow design remains a challenging, slow, and often error-prone process, thus limiting the speed of further adoption of scientific workflows. Based on practical experience with data-driven workflows, we identify and illustrate a number of recurring scientific workflow design challenges, i.e., parameter-rich functions; data assembly, disassembly, and cohesion; conditional execution; iteration; and, more generally, workflow evolution. In conventional approaches, such challenges usually lead to the introduction of different types of "shims", i.e., intermediary workflow steps that act as adapters between otherwise incorrectly wired components. However, relying heavily on the use of shims leads to brittle (i.e., change-intolerant) workflow designs that are hard to comprehend and maintain. To this end, we present a general workflow design paradigm called virtual data assembly lines (VDAL). In this paper, we show how the VDAL approach can overcome common scientific workflow design challenges and improve workflow designs by exploiting (i) a semistructured, nested data model like XML, (ii) a flexible, statically analyzable configuration mechanism (e.g., an XQuery fragment), and (iii) an underlying virtual assembly line model that is resilient to workflow and data changes. The approach has been implemented as Kepler/COMAD, and applied to improve the design of complex, real-world workflows.

“…We can obtain three synchronization processes S101, S211, S311 and three base processes B0, B101, B211. By applying the method that is mentioned by K. van Hee [2], the tree structures of the base processes and synchronization processes in Fig. 5 are respectively shown in Fig.…”
