Priority can be calculated for works-in-process which are not in demand. A priority calculation device () comprises a priority calculation unit () 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 (), 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 (), is supplied into the production stage with higher priority.

Priority calculation device, program, priority calculation system, and priority calculation method

Disclosed are a device, a system, and a method for setting standard work times that take real-world manufacturing capabilities into account. Provided is a standard work time calculation device (), which analyzes fluctuations in production line assessment indices on a per time period basis, and computes standard work times for each region, as classified according to the degree of fluctuation. The standard work time calculation device () comprises a fluctuation coefficient computation unit (), which computes coefficients of fluctuation for the assessment indices, a fluctuation region identification unit (), which identifies regions of fluctuation with coefficients of fluctuation that are greater than or equal to predetermined thresholds, and a standard work time computation unit (), which computes standard work times for regions of fluctuation.
