Purpose: When the workflow changed, resource scheduling optimization in the process of the
current running instance migration has become a hot issue in current workflow flexible
research; purpose of the article is to investigate the resource scheduling problem of workflow
multi-instance migration.
Design/methodology/approach: The time and cost relationships between activities and
resources in workflow instance migration process are analyzed and a resource scheduling
optimization model in the process of workflow instance migration is set up; Research is
performed on resource scheduling optimization in workflow multi-instance migration, leapfrog
algorithm is adopted to obtain the optimal resource scheduling scheme. An example is given to
verify the validity of the model and the algorithm.
Findings: Under the constraints of resource cost and quantity, an optimal resource scheduling
scheme for workflow migration is found, ensuring a minimal running time and optimal cost.
Originality/value: A mathematical model for resource scheduling of workflow multi-instance
migration is built and the shuffled leapfrog algorithm is designed to solve the model.Peer Reviewe
