Abstract: Priority can be calculated for works-in-process which are not in demand. A priority calculation device (110) comprises a priority calculation unit (124) which specifies a queue of lots in each production stage, a product category wherein the lot is to be used, and the number of components included in the lot, on the basis of information stored in a queue information storage area (115), and allocates priority for each lot so that when the specified lot is supplied to the production stage, a lot, by which a ratio of a component, in each product category, contained in a lot which is in a process subsequent to the process of the production stage is made closer to the ratio of demand in each product category specified by the information stored in a demand information storage area (113), is supplied into the production stage with higher priority.

Abstract: A dynamic maintenance planning apparatus including a maintenance planning device and a priority calculating device is provided. The maintenance planning device determines a maintenance date and time on and at which the throughput of a manufacturing system is maximum from among possible maintenance dates and times based on a simulation result in which a specific manufacturing apparatus on a manufacturing system is stopped at a specified maintenance date and time, and, for the maintenance at the determined maintenance date and time, specifies a lot whose completion is predicted to be delayed. The priority calculating device calculates a priority of the lot whose completion is predicted to be delayed so as to prevent waiting time of the lot during the maintenance.

Abstract: The present teaching is intended to observe the delivery date of a product and decrease the number of workpieces in a merger process. A treatment sequence calculator included in manufacturing instruction equipment identifies an in-process part being worked in each process, and calculates the delivery-date allowance of the in-process part. In-process parts whose delivery-date allowances fall below a predetermined threshold are inputted to each process in ascending order of delivery-date allowances. In-process parts whose delivery-date allowances are equal to or larger than the predetermined threshold are inputted to each process in ascending order by a minimum value of remaining treatment times which the in-process parts take to reach the merger process.

Abstract: The present invention provides product delivery deadline compliance and increased worker training efficiency. A worker assignment scheme creation section of a worker assignment device creates a worker assignment scheme and calculates a job completion time for each process step of each product in accordance with a worker assignment rule. An evaluation value calculation section calculates evaluation values concerning delivery deadline compliance and worker training in accordance with processing results produced by the worker assignment scheme creation section. A worker assignment priority change section changes the worker assignment rule in accordance with the evaluation values and target values therefor. The above process is repeated a number of times to produce plural worker assignment schemes, which are compared in accordance with the evaluation values concerning delivery deadline compliance and worker training. The result of comparison is eventually presented to a user.
