TRIZ based tool management in supply networks

The Multi-Agent Tool Management System (MATMS), based on intelligent agent technology for automatic tool procurement in supply networks and provided with a Flexible Tool Management Strategy (FTMS) for optimum tool inventory control, is presented in this paper. The MATMS operates in the framework of a negotiation-based, multiple-supplier network where a turbine blade producer (client) requires dressing jobs on worn-out CBN grinding wheels from external tool manufacturers (suppliers). Tool supply cost minimization involves inventory level minimization, whereas stock-out risk prevention entails inventory constrained maximization. The MATMS integrates the inventive problem solving method, known as the TRIZ method, that can suggest invention directions based on heuristics or principles to resolve the contradictions between production needs and cost minimization.
