DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a manufacturing shop controller.
Regarding the roll device , especially in a job shop type manufacturing shop that manufactures various types, there is a difference between the simulation result and the current situation that the next work to be performed is selected in real time based on the dispatching rule evaluated in advance and the current situation If it does, an alarm is displayed to promote review of the dispatching rules again
Related to a manufacturing shop control device .

[0002]

2. Description of the Related Art In a conventional manufacturing shop control, a work instruction is created by simulation,
The target work of the next process is determined from the workable items by a specific rule.

For example, according to Japanese Patent Application Laid-Open No. 4-304557, a work instruction is issued while appropriately balancing the priority of product delivery and the operation rate of equipment. Further, according to Japanese Patent Application Laid-Open No. 3-161250, a simulation is executed on the basis of various kinds of plan information including the progress of a manufacturing shop and the priority order of waiting lots, and instructions for each operation are efficiently created.

[0004]

As described above, in the conventional manufacturing shop control, the selection of the next processing target in the simulation and the actual work is individually performed, and the next processing target selection rule is changed due to a change in the product mix or the like. Review cannot be performed. Further, it is not possible to recognize whether or not a problem occurs with the rule once determined.

An object of the present invention is to improve the above-mentioned drawbacks by selecting an object to be worked next in real time based on a dispatching rule for each facility evaluated in advance, and comparing the result of the pre-verification with the result of the pre-verification. If an alarm occurs, an alarm is displayed to facilitate reviewing dispatching rules and follow changes in the product mix.
To provide a manufacturing shop control device .

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
I will explain.

FIG . 1 is a manufacturing shop control according to the present invention.
It is a block diagram of one form of the ruler device. In the same figure
Manufacturing shop control device of the invention manufactures many kinds
Job shop type manufacturing shop
Remembers individual manufacturing process steps for all qualifying products
Process flow storage unit 1 and all the production
Stores planned information such as planned launch date and delivery date for products
The production plan storage unit 2 that stores
In-process status that memorizes the current status of in-process products
State storage unit 3 and each production facility existing in the manufacturing shop
Identify and modify dispatching rules that determine the work order.
And a rule maintenance unit 4 for updating and managing
For the production targets stored in the in-process storage unit,
Procedure stored in the process flow storage unit and the rule maintenance
Dispatching rules for each processing facility managed by the department
Simulation that simulates in time series based on
Applicable when the next operation control is selected for each production unit
The delivery margin, priority, and
Process flow information and status of work that can still be performed
A production target that is not
Information on workable time, delivery allowance, priority, and process flow
A shop state search unit 6 for searching for information and the shop
The information searched by the status search unit is managed by the rule maintenance unit.
Then it should work productivity in manufacturing equipment unit on the basis of the rules
A next processing selection unit 7 for selecting an object;
Compare the shop status in real time with the
The result comparing unit 8 for calculating the difference,
And an alarm display unit 9 for displaying the difference.

That is, the manufacturing shop controller described above
The device for each product stored in the process flow storage unit 1
And the production procedure information stored in the production plan storage unit 2.
Information on various production plans and progress of manufacturing shops in real time
A process that grasps the progress status and stores the in-process status at a specific point in time.
The in-process information in the hanging state storage unit 3 and the information stored in the rule maintenance unit 4
It is memorized for each equipment unit that
Simulation using patching rules as input information
The part 5 simulates the flow of the future manufacturing shop.

The shop state search unit 6 is set in real time.
Information on current products that can be processed and future processing
Information, including the time available to start work on products that can be
And the next processing selection unit 7 searches the shop status.
The information of the search unit 6 is managed by the rule maintenance unit 4 for each equipment.
