In a production planning system, the explosion of a product to parts is performed by a specification check device and a design passage judgement device. An MRP calculation control device, a leadtime forecasting device, an MRP explosion calculation device, a work load calculation device and a data input/output device cooperate to estimate a shop load and to calculate a leadtime with a work load and a production capacity taken into consideration, thereby drawing up a production plan. A problem area analysis device analyzes a problematical area in the production plan to display it by graphics of the data input/output device. Various adjustment devices carry out the adjustment of the production plan through a graphic interface.

An electromagnetic flow meter comprises: an excitation member (5) in which a plurality of magnets (5a, 5b, 5c) are arranged spaced apart from one another along an outer circumferential surface of a flow channel (1) through which liquid metal flows, and in which a magnetic field is formed in a direction perpendicular to the outer circumferential surface of the flow channel (1); and electrodes (6a, 6b) provided between the magnets (5a, 5b, 5c) of the excitation member (5), for measuring the voltage generated when the liquid metal crosses the magnetic field. A pulse excitation electric-current supply device (7a) for supplying a pulsed excitation current to the excitation member (5) is provided, whereby a flow speed distribution can be suppressed from being generated in the circumferential direction of the channel (1) even when the flow speed of the liquid metal is low, and the flow rate can be accurately measured.

A production planning system capable of adjusting a production plan comprises a data storage unit for storing production planning information, parts list information, parts stock information and parts warehousing schedule information; a MRP (material resource plan) explosion unit for calculating the required amount of material resources based on the production plan information and the parts list information stored in the data storage unit; and a superfluous parts adjusting unit for making adjustment to eliminate superfluous parts. The superfluous parts adjusting unit includes a superfluous parts calculation section for collating the required amount of material resources calculated by the MRP explosion unit with the parts stock information and the parts warehousing schedule information thereby to calculate the superfluous parts, and a superfluous parts elimination section for eliminating superfluous parts by changing the production plan based on the superfluous parts information calculated by the superfluous parts calculation section.

According to a region dividing device, a region dividing member generates a plurality of primary region groups, each of which includes a plurality of primary regions. Each of the plurality of primary regions is characterized by each measured value of feature values. A basic region group generating member generates a single basic region group that includes a plurality of basic regions produced by dividing the target image. Each basic region is characterized by each measured value of feature values. Each measured value is obtained based on the measured values of the plurality of primary regions of the plurality of primary region groups. A region integrating member integrates similar adjacent basic regions into a corresponding integrated region, based on a weighted Euclidean distance between the similar adjacent basic regions.
摘要:
A method or device for computing material requirements which calculates various parts and materials necessary for products to be produced when a production plan is input, in order to reduce the processing time for a material requirements computation. In order to establish the object, the method or device of computing material requirements is provided, which can perform a parallel process without using conventional low level codes. Parts computing means are respectively assigned to items. When the lower parts computing means receives the computation result of the upper parts computing means, it independently executes the computing process if the computation result is sufficient for the parts computation. The process rate of the material requirements computation can be improved by performing the load distribution under a fixed rule, including that to which computer the data of an item is loaded or by which computer an item is processed, when the material requirements are computed in parallel process using plural computers.
