Abstract

Abstract The present invention comprises a device for production control and a method for production control for setting optimal priorities according to production conditions that may vary from moment to moment. According to the invention, a control means produces production instructions information according to lot information. Included are priorities for the production lots and production instructions conditions. A transport means carries the predetermined production lots according to the production information and outputs primary condition information that denotes the production condition. The invention also enables the processing means to perform a processing based on the production instructions information and output secondary condition information, which denotes a production condition for the production lot transported by the transportation means. Further, the control means determines new priorities based on the priority level and the production conditions for each manufacturing process in case there are a plurality of manufacturing processes to be performed simultaneously.

Claims Analysis

Total Claims: 4

Claim 1

Independent Claim 160 words

A device for production control that comprises: (1) A control means that provides at least each production lot with production instructions information which contains priority information needed to define the order of processing; the control means defines the content of the next manufacturing process based on the current manufacturing conditions, which are identified by lot information that denotes the attributes of each production lot, information that denotes conditions under which each production unit is transported (hereinafter referred to as the "primary condition information") and information that denotes conditions under which each production lot is processed (hereinafter referred to as the "secondary condition information"); (2) A transport means that transports the predetermined production lots based on the production instructions information; the transport means is capable of forming and outputting the primary condition information; and (3) A processing means that processes the production lot transported by the transport means; the processing means is capable of forming and outputting the secondary condition information.

Claim 2

Dependent Claim 50 words

A device for production control as set forth in claim 1, wherein, given a plurality of manufacturing processes to be performed simultaneously, the control means sets priorities based on priority levels and production conditions and establishes production instructions information that defines the content of the manufacturing process receiving top priority.

Claim 3

Independent Claim 162 words

A method of production control that comprises (1) A first process in which at least each production lot is provided with production instructions information which contains priority information needed to define the order of processing; the process defines the content of the next manufacturing process based on the current manufacturing conditions, which are identified by lot information that denotes the attributes of each production lot, information that denotes conditions under which each production unit is transported (hereinafter referred to as "the primary condition information") and information that denotes conditions under which each production unit is processed (hereinafter referred to as "the secondary condition information"); (2) A second process in which the predetermined production lot is transported according to the production instructions information and the primary condition information is formed and output; and (3) A third process in which the production lot transported in the 2nd process is processed based on the production information and the secondary condition information is formed and output.

Claim 4

Dependent Claim 53 words

A method for production control as set forth in claim 3, wherein, given a plurality of manufacturing process to be performed simultaneously, the first process sets priorities based on the priority levels and the production condition and establishes the production instructions information that defines the content of the manufacturing process receiving top priority.
