A digital eco-factory has been proposed by the authors for sustainable manufacturing. When a digital eco-factory is used, green performance is examined in addition to productivity and manufacturability. In this paper, this digital eco-factory concept is applied to a PCA (Printed Circuit Assembly) line for review of electric power consumption. This trial shows how to construct a digital eco-factory. A PCA line consists of a solder paste printing machine, several electronic part mounters, a reflow furnace and a testing machine. Models for these devices are prepared as e-catalogues. E-catalogue contains a state transition model of the device. Each state description in the state transition model includes computational expression for computing the power consumption. Parameters in the computational expression consist of machine specific values, and also consist of variables which are provided at a simulation executing time. When constructing a virtual PCA line, device agent descriptions are generated based on e-catalogue. PCA line agent and PCB (Printed Circuit Board) agent are generated based on production scenario. A PCA line agent manages operation of the virtual PCA line. A PCB agent is an object product of assembly process. The simulation of power consumption is successfully performed on the constructed virtual PCA lines.
