Abstract: Provided is an electrode sheet manufacturing apparatus that forms an electrode sheet by cutting a sheet stack including an electrode composite material layer and a separator provided on the electrode composite material layer. The electrode sheet manufacturing apparatus includes a laser irradiation device that irradiates the sheet stack with a first laser beam having a wavelength to be absorbed by the separator and a second laser beam having a wavelength to be absorbed by the electrode composite material layer, and a controller that controls driving of the laser irradiation device. The controller moves an irradiation position of the first laser beam relative to the sheet stack and moves an irradiation position of the second laser beam so as to follow a track of the irradiation position of the first laser beam.

Abstract: A digital twin simulation is executed. In this simulation, a personal relationship level between two workers included in multiple workers is calculated. Further, based on the personal relationship level between the two workers and data of work content of the work scheduled to be executed in a work line of a real space, an assignment pattern of workers satisfying a reference condition in which a work efficiency in a whole work line of a digital space is equal to or greater than a target value is searched.

Abstract: A separator-integrated electrode plate includes a current collector plate; an active material layer formed on the current collector plate; and a resin separator layer formed on the active material layer. A belt-like laser-cut end portion along a laser-cut edge that is laser-cut in a thickness direction of the separator-integrated electrode plate and forms part of a peripheral edge of the separator-integrated electrode plate has a resin-permeated portion in which a resin forming the resin separator layer permeates the active material layer over a width that is more than twice a thickness of the resin separator layer.

Abstract: The operation management system manages an operation of a line composed of a plurality of cooperating work subjects. The operation management system performs: setting, for each work subject, an intensity that decreases at a speed corresponding to a work speed, recovers by a recovery action, and is given a lower limit value; receiving a target handling plan for the line; creating an operation plan including at least the working speed and a timing of the recovery action by using a simulation model obtained by modeling the line so that the target handling plan is achieved while maintaining the intensity of each work subject at the lower limit value or more; and allowing the intensity of each work subject to temporarily decrease to less than the lower limit value in creation of the operation plan in response to the target handling plan exceeding a predetermined reference value.

Abstract: A work line includes: a first work carried out by a first target worker; and a second work carried out by a second target worker on a resultant product of the first work. A first model motion is a model motion when the first target worker passes the resultant product of the first work to the second target worker. A second model motion is a model motion when the second target worker receives the resultant product of the first work from the first target worker. When the first target worker carries out the first work in a virtual space, a simulation system draws a first model worker performing the first model motion in the virtual space. When the second target worker carries out the second work in the virtual space, the simulation system draws a second model worker performing the second model motion in the virtual space.

Abstract: A simulation system simulates a predetermined work in a virtual space. A comment database indicates a correspondence relationship between a comment created by a reference worker regarding the predetermined work and a characteristic of the reference worker. The simulation system acquires information on a model motion that serves as a model when carrying out the predetermined work. The simulation system acquires information on a characteristic of a target worker carrying out the predetermined work. The simulation system extracts the comment associated with the characteristic of the reference worker corresponding to the characteristic of the target worker, based on the comment database. When the target worker carries out the predetermined work in the virtual space, the simulation system draws a model worker performing the model motion in the virtual space and presents the extracted comment to the target worker.
