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.

Production planning system

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.

Method and device for computing material requirements

In a design aiding method, a design aiding apparatus having the method, or a design aiding system possessing a plurality of such design aiding apparatuses for use in a field of computer software to facilitate a design process, there is determined, for a product having many variations of attributes and values thereof, an appropriate design procedure according to a state of design in a process of determining the attribute values of the product satisfying a request of a client. At occurrence of, for example, conflict during the design, the design procedure is guided for the user to obtain a design plan conforming to the request.

Method and apparatus for aiding of designing process

In the invention, shapes of an insertion head, a jig and components are indicated to enable updating and new registration, and the relative position between the components and the mounter and the mounting process, the mounting sequence and the collision state of each component are indicated. Thereby input of data is facilitated and error of the data can be easily found. Data required at indicating the collision state indication and the name of the mounter to mount the component and the mounting direction, need not be stored by the user.

Apparatus for and method of preparing numerical control data for

The present invention relates to a computer system which can store assembly information and component information for components to be automatically inserted by an insertion machine into a printed board, which can perform required operations based upon the information stored, and which can display and output results of the processings. In the present method, the system checks for possible mechanical interference, when inserting a component, between an insertion head and other components having the possibility to be inserted prior to the component prepares preceding relations of insertion order from the results of an interference checking, selects the components which cannot be inserted automatically according to the preceding relations of insertion order, and modifies insertion processes or insertion directions thereof, decides insertion order of the components according to the modified insertion processes or the insertion directions, and, at last, automatically prepares and outputs numerical control data relating to the automatic insertion of said components.

Method of and apparatus for preparing numerical control data for

Machining data for machining a workpiece is divided by an NC data dividing processor into a plurality of machining element data each of which can be carried out by a single tool, and selected ones of the divided machining element data are combined and edited by an NC data editing processor in accordance with job allocation determined by a job allocation processor.

Numerical control data dividing and editing apparatus for numerical

A robot control data processing apparatus comprises a robot control data dividing processor for dividing robot control data adapted for monitoring and controlling robots into a plurality of operation elements and storing the robot control data in units each forming an operation element, and a robot control data editing processor for selectively combining and editing one or more of the plurality of the divisional operation elements. The robot control data is prepared by teaching the robots in operation and/or programming a robot oriented language.
