An aggregate resource model for the provision of dynamic ‘resource-aware’ planning

Abstract

The realization of agile enterprises requires substantial development of the underpinning modelling, information management and knowledge representation technologies. This paper introduces a resource model that has been developed to support the dynamic, aggregate planning of manufacturing operations within large, complex production networks during the formative stages of design. The main goal of aggregate planning is the measurement of product manufacturability and the evaluation of alternative design configurations and manufacturing scenarios, through the allocation of multiple parts to remote facilities within the supply network. The term ‘resource aware’ planning is used to indicate the creation of a dynamic interrelationship between the planning entities (products and processes) and the enterprise resources, including humans and machines. The technologies employed for implementing the pilot methods include the aggregate resource modelling methodology, a web-centric co-development environment, unique methods for enriching planning entities with knowledge and evolutionary computing methods for the rapid generation and optimization of production routes. A pilot resource aware planning system has been implemented that supports many innovative modes of operation, the initial testing of which was very encouraging.
