A Top-down Mapping and Federated-based Coordination for Supply Chain Management Systems using an ERP System

摘要

This paper presents development of a top-down mapping mechanism for modeling and coordinating a federation of Distributed Discrete Event Simulation (DDES) models representing intra supply chain entities using an Enterprise Resource Planning (ERP) system as the federation coordinator. The ERP or Supply Chain Management (SCM) Headquarters system uses a traditional coordination cycle (in fast mode) to correct infidelities in data and status. The ERP system, which is typically used as a coordination tool for interactions between complex highly variable manufacturing systems, serves to coordinate and synchronize complex highly variable simulation models of these same systems. Before implementing the ERP-based coordination methodology for a federation, a formal information model, which contains static and dynamic information of the problem domain using Unified Modeling Language (UML) and Supply Chain Operations Reference (SCOR) model, is developed to provide formal semantics and ontological characteristics of the system. From this formal model, a top-down mapping mechanism of the federation objects and processes with potentially different granularities is presented in order to make an entire federation functional.
