Further, as an attribute of the washer inner diameter restricting object, a conditional expression is set such that the washer manufacturing inner diameter is smaller than a value obtained by subtracting 5 from the bar material raw material diameter and larger than 1.5 times the tool width. The work time is set as an attribute of the cut-out time object by a mathematical formula (work time = (equipment coefficient) × {(raw material diameter) − (production outer diameter)} + (equipment coefficient) × (production inner diameter)).
The washer cutting object consumes the bar material object and generates a washer object.

Next, an NC lathe A object as a work unit will be described as an example of a resource object.

  The Capability profile regarding the item object, work object, and resource object set in this way has the structure shown in FIG. The example of FIG. 12 uses an ISO 15745 (Industrial automation systems and integration-Open systems application integration framework-) standard framework.

Next, a manufacturing system development support apparatus 1 according to Embodiment 1 of the present invention will be described.
FIG. 13 is a functional block diagram of the manufacturing system development support apparatus according to Embodiment 1 of the present invention.
As shown in FIG. 13, the manufacturing system development support apparatus 1 includes a manufacturing system information storage device 10 and a process design / resource allocation device 11.
The manufacturing system information storage device 10 includes an item object storage unit 14, a work object storage unit 15, a resource object storage unit 16, a process information storage unit 17, and an allocation information storage unit 18.
The item object storage unit 14 stores an item object input from the outside. The work object storage unit 15 stores work objects input from the outside. The resource object storage unit 16 stores resource objects input from the outside. The process information storage unit 17 stores the process information created in the process design unit 19. The allocation information storage unit 18 stores the allocation information created in the resource allocation unit 20.

The process design / resource allocation device 11 includes a process design unit 19, a resource allocation unit 20, and a manufacturing facility construction unit 21.
The process design unit 19 creates process information using item objects and work objects for which capabilities are set.

  The algorithm for creating this process information is as follows. Extract the item information of the product in the design bill of product design information, search the item object tree by the extracted item, and extract the item object. Then, a work object that retrieves the extracted item object by retrieving the work object is extracted. Then, the item object consumed by the extracted work object is extracted. This is repeated until the work object becomes a work object for purchasing materials or parts.

It is determined whether or not the process order can satisfy the required specifications of the product design information. If it cannot be satisfied, process design of another route is performed. On the contrary, when it is satisfied, the extracted item object and work object are collectively stored in the manufacturing system information storage device 1 as process information per route.
Then, process information relating to a new route is generated until the process cannot be developed, and stored in the manufacturing system information storage device 1.

The creation of process information performed in the process design unit 19 will be described with reference to FIG. FIG. 14 is a process diagram created when an item E is ordered as a product.
If the product specified in the input order is the item object E, the work object C for generating the item object E is selected from the relationship between the objects. At this time, a plurality of work objects may be selected, but in the following description, only one is selected. In the case of a plurality of processes, process information is created for each.
The item object B and the item object D related to the work object C are selected.

  Next, with respect to the item object B and the item object D, the work object A and the work object B are selected, respectively. Next, the item object A and the item object C consumed by the work object A and the work object B are selected. The item object, the work object and the relationship obtained in this way are process information.

The process allocation unit 23 allocates processes to resource objects and creates allocation information. That is, resource objects A, B, and C related to the work objects A, B, and C are allocated. The relationship between the work object and the resource object is allocation information.
The process information and allocation information obtained in this way are stored in the process information storage unit 17 and the allocation information storage unit 18, respectively.

  Next, how a work object is extracted using a specific example will be described with reference to FIG. The process for manufacturing the product X is designed. The work object that produces the item X object is searched, and the assembly process object is extracted. Then, the item object consumed by the assembly process object is searched, and the item C object and the item D object are extracted.

  The work object that produces the item C object is searched, and the keyway machining object is extracted. Then, the item object consumed by the keyway processing object is searched, and the item C1 object is extracted.

A work object that produces the item C1 object is searched, and a lathe machining object is extracted. Then, the item object consumed by the lathe processing object is searched, and the material M2 object is extracted.
The work object that produces the material M2 object is searched, and the material purchase object is extracted.
Similarly, the item D object is extracted. When these are put together, process information as shown in FIG. 16 is generated.

Next, creation of allocation information will be described with reference to FIG. 17 using a specific example. FIG. 17 shows process information and allocation information created when a washer order is input.
Consider the process design when the washer order is entered as the required item. As the required specification of this washer, an inner diameter of 40 mm or less and 10 mm or more are specified. Select a washer object that satisfies the corresponding specifications from the item object. Then, a work object for generating the washer object is selected from the attribute of the washer object. In the case of this example, the transport object, 40 cutting process object, and bar material set object of the unit work are selected. Next, an item object consumed by the 40 cutting process object is selected from the attributes of the 40 cutting process object. In this example, the bar material 40 object is selected. In this way, the bar material 40 object, the bar material 40 object are consumed, and process information including a series of work objects and washer objects for generating the washer objects is obtained.

  Next, a resource object that can be used by the 40 cutting process object is selected from the attributes of the 40 cutting process object. In this example, the NC lathe A object is selected. In this way, the NC lathe A object is assigned to the 40 cutting process objects. In addition, the bar material set object assigns the worker 1 object and the NC lathe A object. The transfer object assigns a moving device object. This is allocation information.

  When the specification of the required item is input in this way, process information is generated by selecting an item object that satisfies the specification and a work object. When the item object and the work object are determined, the resource object can be allocated.

  Also, by describing the facility information, item information, or work information with constraint formulas using variables, the constraints between the facility information, item information, or work information can be described in detail, making it possible to describe manufacturing requirements and manufacturing capabilities. There is an effect to increase.

FIG. 18 is a diagram for explaining the flow of creating a capability of a production line that is system-integrated by performing process design from the required specification of the production line.
Next, the process design from the required specification of the production line and the creation of the system integrated capacity of the production line will be described.
Among the items A, A and B showing the required specifications of the production line, the process is designed for the operation A, and as shown in FIG. 18, the lower two operations AA, operation AB and operation AA are produced and the operation is performed. Expands to item C consumed by AB. Then, catalog information or the like is searched for the specifications of resources satisfying the required specifications consisting of item A, work AA and item C, and if there is a corresponding resource, it is assigned. Further, the catalog information or the like is searched for a resource specification satisfying the required specifications composed of the item C, the work AB, and the item B, and if there is a corresponding resource, it is assigned.

  In the case of the above-described example obtained by performing the process design in this way, two requirement specifications (a first requirement specification composed of item A, operation AA and item C, and a second requirement consisting of item C, operation AB and item B). Resource A and resource B satisfying the requirement specification (1) are allocated, and the first requirement specification and the resource B capability are stored as the resource A capability.

Embodiment 2. FIG.
FIG. 19 is a functional block diagram of a manufacturing system manufacturing apparatus according to Embodiment 2 of the present invention.
As shown in FIG. 19, the manufacturing system development support apparatus 1B according to the second embodiment of the present invention includes the manufacturing system development support apparatus 1 according to the first embodiment, an item object storage unit 14B, a work object storage unit 15B, a resource. Since the object storage unit 16B is different and the other parts are the same, the same parts are denoted by the same reference numerals and the description thereof is omitted. The item object storage unit 14B, work object storage unit 15B, and resource object storage unit 16B store item objects, work objects, and resource objects in a hierarchy.

Resources are classified into four layers as shown in FIG.
When the resources are arranged from the top to the bottom, as shown in FIG. 21, a work center, a work unit, an action unit, and a processing unit are obtained.
Furthermore, the work units are classified into devices that are subclasses, as shown in FIG. The apparatus is classified into sub-classes of manufacturing apparatus, transport apparatus, inspection apparatus, and storage apparatus.
The operation unit is a resource having individual entities constituting the work unit. The operation unit is classified into workers and devices which are subclasses.
In addition, the processing units are classified into jigs and tools that are subclasses.

Items and work objects can also be classified into hierarchies corresponding to resource hierarchies as shown in FIG.
When items are arranged in order from the top to the bottom, work in progress (Work In Process), execution work (Work under Execution), operation work (Work under Action), processing work (Work under Processing).
Work-in-process is an item that is input or produced in units of workplaces. An execution work is an item that is input or produced in units of work units. An operation work is an item that is input or produced in units of operation units. A processing work is an item that is input or produced in units of processing units.

In addition, when the tasks are arranged in order from the upper level to the lower level, they become element work (Element Process), unit work (Unit Process), operation (Action), and processing (processing).
Elemental work is work performed in units of workplaces, and as shown in FIG. 23, there are manufacturing work, inventory work, maintenance work, and quality work as instances.
A unit work is a work that constitutes an element work, and is set in units of work units. When one work place is constituted by a plurality of devices, it is set for each device. Unit work includes processing work, assembly work, transfer work, and inspection work as instances.

In addition, the operation is an operation set for each operation unit, and is a basic element in performing control related to manufacturing. A unit work consists of a plurality of consistent operations. The operations include sequence control, motion control, NC, process control, and robot control as instances.
Processing is a unit constituting a processing method, and is an operation performed using a processing unit. When different combinations of processing units such as tools and jigs are required, the processing is different. Processing includes processing processing, assembly processing, surface processing, pre- and post-processing, movement processing, and inspection processing as instances.

An object belonging to an upper hierarchy is composed of one or more lower hierarchy objects. Further, the objects in the lower hierarchy are aggregated into at least one object belonging to the upper hierarchy.
In addition, regarding items, objects belonging to the upper hierarchy are not composed of objects belonging to the lower hierarchy, but the attributes, operations or relationships of objects belonging to the upper hierarchy are inherited by the objects belonging to the lower hierarchy. Yes. For example, the work-in-process object input to the work place is inherited by the execution work object input to the work unit, and the object is inherited by the operation work object input to the operation unit.

24 shows a hierarchical model of manufacturing information according to the hierarchical definition of FIG. 21 as a relationship between objects. Each object cannot be related to any object other than the object of the hierarchy to which it belongs or the object of the hierarchy adjacent to the top and bottom. Each object can refer to the same type of object as itself as a parent.
FIG. 24 shows the relationship among the objects of resource information, item information, and work information. When viewed in the same hierarchy, the element work and unit work as work information are subordinate to the work place and work unit as resource information. For example, element work information based on a certain work place cannot be used if the work place is different.

FIG. 25 shows an object related to the instruction information added to FIG.
For the instruction information, one item information is designated in the same hierarchy. Also, one piece of work information that can produce the item is specified. By specifying production work information, resource information can also be specified. For example, in response to an execution instruction such as 100 workpieces, a unit operation and a work unit are determined, and after determining which equipment and how to produce, a specific operation method (recipe, etc.) is instructed.

Embodiment 3 FIG.
FIG. 26 is a configuration diagram of a manufacturing execution system according to Embodiment 3 of the present invention.
The management apparatus of the manufacturing execution system according to the third embodiment of the present invention is connected to the manufacturing system development support apparatus 1 via the communication line 8 as shown in FIG. Since it is the same, the same code | symbol is attached | subjected to the same part and description is abbreviate | omitted. The management apparatus 3 of the manufacturing execution system and the manufacturing system development support apparatus 1 may be connected via the network 4.

  As shown in FIG. 27, the management apparatus 3 according to the third embodiment sets a process schedule based on the process information in accordance with the production order request unit 31 that requests production of a finished product and the production order of the production order request unit 31. A process scheduling unit 32 to be created, and a manufacturing execution unit 33 that makes a manufacturing process instruction a facility apparatus 2 based on the process schedule and the allocation information are provided.

The production order requesting unit 31 receives specifications, number of pieces, and delivery date of requested products input from the outside.
The process schedule unit 32 retrieves the corresponding process information from the manufacturing system information storage device based on the specifications of the requested product. Then, a process schedule for producing the required number by the predetermined delivery date using the process information is created.
The manufacturing execution unit 33 selects, from the allocation information, the equipment device allocated by the corresponding work based on the process schedule.
Further, the manufacturing execution unit 33 can read the allocation information again from the manufacturing system information storage device and execute the work specified in the process schedule when it obtains the defect information from the target equipment device that has issued the manufacturing process command. Select another equipment and issue a manufacturing process command to the equipment.

In this way, a process schedule is created based on the process information stored in the manufacturing system development support apparatus 1, and the manufacturing process is performed on the facility apparatus 2 to which the process determined by the process schedule is assigned based on the allocation information. By giving an instruction, it is possible to change the dynamic process and assign the equipment 2 to the production order corresponding to the manufacturing system information.
Further, by updating the manufacturing system information stored in the manufacturing system development support apparatus 1, the management apparatus 3 can cope with the expansion or change of the manufacturing system.

  Further, when the assigned equipment device 2 becomes unusable, the management device 3 searches the manufacturing system information stored in the manufacturing system development support device 1 and uses the other equipment devices 2 that can be used in the process schedule process. And a manufacturing process command is given to the equipment device 2, so that even if a malfunction occurs in the equipment device 2, it can be dealt with quickly.

  Further, since the manufacturing system information is described in a language that can be read by the manufacturing execution system 5, the manufacturing system information can be used for construction and management of the manufacturing execution system.

  In addition, since common information included in the manufacturing system information is aggregated and stored as a class, it is easy to search for and use a similar equipment device 2, item, or manufacturing method.

  Further, the management apparatus 3 uses the manufacturing system information obtained by designing the manufacturing method, designing the manufacturing apparatus, or designing the manufacturing line by storing the manufacturing system information in a hierarchy based on the hierarchy of the equipment device 2. Thus, it is possible to support not only production management but also acquisition of quality information for quality control and acquisition of operation information for improving manufacturing efficiency.

  In addition, by updating the manufacturing system information, it is possible to realize a production management system that can cope with expansion and change of the manufacturing system.
