Considerations on Resource Usage in Exceptions and Failures in Workflows

TL;DR

This paper reviews various perspectives on how resource unavailability causes failures and exceptions in workflows, highlighting different interpretations based on authors' views of dynamic systems.

Contribution

It provides a comparative analysis of multiple viewpoints on resource-related failures and exceptions in workflow modeling.

Findings

Different authors interpret failures differently based on system context.

Resource unavailability is a common cause of workflow exceptions.

Understanding these interpretations aids in designing more robust workflows.

Abstract

The paper presents a description of some point of view of different authors related to the failures and exceptions that appear in workflows, as a direct consequence of unavailability of resources involved in the workflow. Each of these interpretations is typical for a certain situation, depending on the authors' interpretation of failures and exceptions in workflows modeling real dynamical systems.
