The Digital Eco-Factory proposed by the authors evaluates the production conditions including environmental indicators from an equipment and product view by executing a simulation using a virtual production line. In this paper, the Digital Eco-Factory for PCA (Printed Circuit Assembly) is discussed. The virtual PCA line is constructed by multi equipment agents which are generated based on equipment models. Production conditions are evaluated about power consumption of entire line from the product viewpoint. The equipment models include behaviour descriptions as states and their transitions. Each state is embedded with equations for calculating power consumption. The equipment agent includes communication functions with a PCB agent for controlling of product flow to manage the timing of the input of the product to each equipment on the virtual line. Experimental executions of a simulation using the constructed virtual PCA line show the effect of product flow.
