Abstract: An automatic article transport system capable of transporting a plurality of articles to respective destination positions within a short time and at high efficiency. The system includes a plurality of fixed rails, a plurality of movable rails each capable of running along a pair of fixed rails, and a plurality of hoists capable of running on the movable rails and of lifting and lowering a member to be transported. Controllers are installed on the movable rails and the hoists, respectively. The system further includes a central controller having a table and a device for generating a path for a member to be transported, and transmitters for transmitting control electric power and control signals between the central controller and the controllers installed on the movable rails and the hoists. A transport path for a member to be transported is determined in the path generating device on the basis of data on members to be transported, transport sequence data, and equipment and structure data.

Abstract: A work management system has input means having a function of inputting coordinate information from the surface of a panel, output means having a function of projecting electronic information onto the panel, and data processing means for executing a predetermined processing, e.g., preparation and input processing of a form, a chart or a drawing, retrieval, editing, totalization, etc., by establishing a correspondence between the information projected on the panel by using the output means and the coordinate information input from the input means. The data processing means displays a list of registered items to be designated in a window for selection of one of the items, whereas, when coordinate information is input from two points for an entry column for time setting, the data processing means draws a bar between the two points. Control information which is conformable to working hours of equipment at a work site, e.g.
