As recent trend has shown that consumers are buying products that reflect their own personality and characteristic, it implies that in order to fulfill the needs of individual customer, manufacturing system in the future shall be individual oriented. Parallel with the popularization of placing order via the internet, this research develops and analyzes an internet-based consumer oriented product ordering system modeled by colored Petri nets. The system is linked to the manufacturing system where the delivery date and cost of product is precisely calculated based on the machine, man power and material factors. It is hope that the system may lead to an outline of future mechanism of individual consumer oriented manufacturing system.
