A group creation unit creates in accordance with predetermined conditions at least one group that includes at least one of a plurality of products to be manufactured. A schedule creation unit creates a schedule for manufacturing the plurality of products for each of the at least one group. A display control unit displays on a display unit the schedule for each of the at least one group, together with information on a task for manufacturing each of the at least one of the plurality of products included in the at least one group.

A first storage unit stores a main component table holding design information of products. A second storage unit stores a sub-component table holding the design information of the products and an update deadline of the design information for each predetermined unit constituted by products manufactured on the basis of the same design information. A first determination unit determines whether or not the main component table has been changed. A second determination unit determines whether or not a present date is before the update deadline. The second determination unit reflects contents of the change performed on the main component table on the sub-component table in a case where the main component table has been changed and the present date is before the update deadline.

A production management system 100 includes an operating state acquisition apparatus 20a and a production management apparatus 10. The operating state acquisition apparatus 20a includes a detector 21a that is retrofitted to be mounted on a production equipment 31 disposed on a manufacturing line L1 or retrofitted to be disposed in a vicinity of the production equipment 31, and which outputs a detection signal indicating an operating state of the production equipment 31, and includes a transmitter 22a that transmits the detection signal. The production management apparatus 10 includes a generator for generating information on production state of the manufacturing line L1 by use of the detection signal received from the operating state acquisition apparatus 20a, and includes a display device for displaying the generated information on production state.

An embodiment method for operating by a controller a cell based mobility production system which produces various kinds of mobilities with a plurality of cells connected in series or in parallel includes arranging a necessary task for each cell in consideration of a mobility production target and a deviation of utilization rate between the cells, setting a sequence of the cells through which a vehicle body matched for a type of mobility passes in consideration of the task arranged for each cell, and determining a feeding sequence of each type of vehicle body in consideration of the sequence of the cells through which each type of vehicle body passes.
