Hybrid system dynamic—discrete event simulation-based architecture for hierarchical production planning
Multi-plant production planning problem deals with the determination of type and quantity of products to produce at the plants over multiple time periods. Hierarchical production planning provides a…
Reference-based indexing of sequence databases
This work considers the problem of similarity search in a very large sequence database with edit distance as the similarity measure, and considers two novel strategies for selecting references as well as a new strategy for assigning references to database sequences.
Distributed optimisation method for multi-resource constrained scheduling in coal supply chains
We consider an integrated planning and scheduling problem motivated by the coal supply chains in Australia. The problem considers production planning of several independent mines. The mines need…

A hybrid simulation-based production planning architecture consisting of system dynamics component at the higher decision level and discrete event simulation components at the lower decision level is presented and results from a single-product manufacturing enterprise demonstrate the validity and scope of the proposed approach.
Impact of modelling approximations in supply chain analysis – an experimental study
This paper presents a study of the comparison of the quality of results obtained at different levels of detail using a supply chain simulation. Analysis of supply chain is typically carried out using…
