Abstract: A new operation is added to an operation plan while reducing the change amount in switch costs before and after change. An operation-plan scheduling device according to one embodiment is provided with a reader to read an operation plan, switch-cost information, information of an additional operation; a graph-network creator to create a graph network by setting intervals between operations allocated to the operation executors as an interval vertices, connecting edges among an entry vertex, an interval vertex, and an exit vertex, and setting weight variables on the edges; a path selector to select a path based on edge weight sums of the paths from the entry vertex to the exit vertex of the graph network; and an operation-plan creator to exchange operations between the operation executors in accordance with the selected path and allocate the additional operation to the interval created by the exchange.

Abstract: There is provided a scheduling device in which a dividing unit selects a predetermined number of semi-finished products from a head out of a semi-finished products for which scheduling order was determined, and divides selected semi-finished products according to a plurality of patterns to generate a plurality of set sequences, the set sequences each being a sequence of one or more sets each including at least one semi-finished product; a calculating unit assigns, for each of the set sequences, the sets included in the set sequence to different ones of the processing devices so that processing of all the semi-finished products are completed fastest, and finds the set sequence that completion time is completed fastest among the set sequences; and a determining unit determines that a top set in the set sequence found by the calculating unit is processed by the processing device assigned thereto.

Abstract: A windshield glass support structure includes a windshield glass (1), a lower end support member (3) supporting a lower end portion of the windshield glass, and a dynamic damper (7) provided at a position corresponding to a resonance antinode of the lower end support member. The dynamic damper is an additional vibration system including an additional spring and an additional mass with respect to a main vibration system in which a glass support rigidity of the lower end support member is a main spring and the windshield glass is a main mass. A resonance frequency of the dynamic damper is set in a frequency band in which the additional mass vibrates in an antiphase with respect to a vibration phase in which the lower end portion of the windshield glass vibrates in a resonance node in a front-back direction of the vehicle caused by a vibration input.
