The analysis for the behavior of the artifacts adopted in a workflow can help preventing the execution errors. A temporal (structured) workflow, TS Workflow, is described with the min and max execution time intervals for each process and modeled by control structures (Sequence, AND, XOR, Loop). In the past, the anomalous behaviors of artifacts in a workflow are redefined to simplify artifact analysis in a workflow. However, some anomalies detected in the previous work might not occur if the temporal factors are considered in each process, because their corresponding processes cannot run continuously or concurrently due to temporal factors. In this work, the analysis work is improved by filtering out above anomalies in a TS workflow. Our work also handles the loop structure that complicates the analysis work and was not concerned in conventional analysis works.
