Abstract
This paper provides an ontology-based set of Petri-nets for simulating the effect of business process changes on an organisation’s li- quidity, and demonstrates that certain types of business process redesign can increase or reduce the amount of external funding that is required to prevent an organisation from defaulting on its debt. This debt defaul- ting may lead to proliferating liquidity constraints for subsequent supply chain partners. Consequently, this paper provides a proper toolkit for assessing and mitigating the propagation of liquidity constraints in sup- ply chains. The paper uses the accounting-based Resource-Event-Agent ontology to create workflow patterns for modelling exchanges between supply chain partners and for the value chains that represent an orga- nisation’s internal processes. Both the exchange and internal processes continuously convert money into resources and vice versa. These mo- dels for money to resource and resource to money conversions are then used for constructing supply chain models for liquidity modelling and analysis.
