DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing one embodiment of the present invention. In the example of FIG. 1, the processing devices are A1, A2, and B to E6.
Are provided. In the processing apparatus, A1 and A2 have the same function. Control devices 2A1, 2A2 and 2B-
2E is connected to the processing devices A1, A2 and BE, respectively. In the example of FIG. 1, one processing device is connected to each control device, but a plurality of processing devices may be connected to one control device.

The storage means 21 is provided in each control device, and stores the product agent 3 and the device agent 4A.
1, 4A2 and 4B to 4E are provided.

The control section 22 is provided in each control device, and controls a control function of the control device. Device Agent 4A
1, 4A2 and 4B to 4E act on the control unit 22 to execute the control function of each control device.

The queue storage means 23 provides an area where the reservation agent forms a processing queue. The reservation agent will be described later.

The network 5 includes control devices 2A1, 2A
2 and 2B to 2E and the production command management unit 6 are connected. The production command management unit 6 communicates with each control device via the network 5 and manages product production. The production command management unit 6 also generates the product agent 3. Normally, the product agent 3 is automatically generated according to a product introduction schedule. A recipe is specified for the product to be introduced. Alternatively, the production command management unit 6 generates the product agent 3 when receiving an instruction from the operator. Like the product agent 3, the production command management section 6 also has a communication function,
It is possible to receive a notification from the product agent that "a processing device with this function has failed and cannot be used".

The product agent 3 has a recipe describing a product production procedure, selects a processing device required for processing according to the recipe, and requests a control device connected to the selected processing device for processing. When a failure or traffic congestion of the processing device is detected, the fact is notified to the production command management unit 6.

The device agents 4A1, 4A2 and 4B
4E are provided one-to-one with the processing devices A1, A2 and BE, and have information unique to the processing device, such as what processing can be performed by the corresponding processing device, and control the processing device. The product 7 is processed according to the production procedure.

The operation of the system shown in FIG. 1 will be described. The product agent 3 sends a message to an apparatus agent corresponding to the processing apparatus to select a required processing apparatus according to the recipe and inquires whether the work is possible. When the product agent obtains the use permission of the processing device from the device agent, the product agent moves to the control device where the device agent is located and requests the processing. Along with this, the product moves to the processing device corresponding to the device agent to which the product agent has obtained use permission.

When the necessary work is completed at the destination, the necessary processing equipment is similarly searched for and processed in the next production procedure. By repeating this, the final product is made up.

The product agent can also search for and make a reservation for a processing device required in the previous production procedure. The product agent waits for a use permission message if a processing device required for the next processing is in use. At this time, a reservation may be made for a processing device group having the same function, such as the processing devices A1 and A2, and an earlier available device may be selected.

FIG. 2 is a diagram showing a reservation state of the processing apparatus. In the example of this figure, the product agent makes a reservation in a queue on the control device for the processing device B in use. It is the reservation agent that actually queues up. The reservation agent is an agent that reserves a processing device prior to the current processing. If the product agent cannot find the necessary processing equipment, it issues an error message and waits for a certain time.

As described above, while the product agent is waiting for processing, the product remains in the processing device or the shelter of the previous production procedure in a state of waiting for processing. The product agent performs message communication with the device agent and other product agents, and learns the degree of congestion of the processing device from the number of reservations and the estimated processing time. Further, a failure of a processing apparatus may be known by broadcast communication from a management agent that manages the agent.

FIG. 3 is a diagram showing an operation of generating a product agent. The recipes R1 and R2 describe functions required for processing in each production procedure. The function a is realized by the processing apparatus A1 or A2, and the functions b, c, d, and e are realized by the processing apparatus B,
C, D, and E are realized respectively. The product X is made by the recipe R1, and the product Y is made by the recipe R2.
Although not shown, recipes are also prepared for products Z and W.
The scheduled launch of the specified product is products X, X, Y, Z, W,
X ... in that order. Recipes are prepared in this order.

Normally, the raw command management section 6 generates a product agent according to a designated introduction schedule.

Returning to FIG. 2, the product agent X7 finishes the processing in the processing apparatus A1, and searches for a processing apparatus having the next necessary function b. Then, the product agent X7 looks at the queue Q of the processing device B, and determines from the number of reserved agents and the scheduled processing time that the product agent X is busy, the production agent management unit 6 sends a message “function b "Congestion".

The production command management unit 6, which has received the notification, suppresses generation of a product in which the function b is written in the recipe, and inputs a product in which the function b is not written first. In the example of the figure, the production of the product X is suppressed and the introduction of the product Y is performed first.

As shown in FIG. 2, the product agent not only detects a failure or traffic congestion at the time of selecting / reserving a processing apparatus, but also receives a notification regarding a failure or abnormality of the processing apparatus from another detected product agent. You may know. In addition, even if there is no problem when a reservation is first placed in the queue of the processing apparatus, there may be a case where a reservation of a high-priority product agent interrupts and congestion occurs. In this way, the product agent, which knows the traffic jam or the failure of the processing device, adjusts its own reservation schedule as follows.

The product agent X0, which has detected in step S1 that there is no necessary processing equipment or that it is crowded,
The procedure before the procedure S1 can be delayed. For example, the reservation of the processing device required in the procedure before the procedure S1
Yield to another product agent that can proceed with production first. That is, the reservation of the product agent X0 is exchanged with the reservation of the product agent entered after this. Conversely, the product agent X0 can delay a reservation made for a procedure after the procedure S1.

The product agent (for example, the product agent X8 in FIG. 3) which has not actually started the production has the same function, and when a traffic jam or a failure of the processing apparatus is detected, the production agent continues until the production can proceed smoothly. Do not start.

FIG. 4 is a block diagram showing another embodiment of the present invention. In FIG. 4, the same components as those in FIG. In FIG. 4, device agents 4A, 4B, 4C, and 4D correspond to processing devices A, B, C, and D, respectively. The product agents 31, 32, 33, 34 are products 71, 7
2, 73, and 74 respectively.

In FIG. 4, the product agents 31, 32,
It is assumed that both 33 and 34 have the same product production procedure, and perform processing in the order of processing devices A → B → C → D. However, each product agent dynamically searches for and selects a processing device having a function required for processing. At this time,
It is also possible for the product agent to pre-read the production procedure and make a reservation in the processing equipment.

The processing device can be reserved by a method in which the device agent manages a queue of the reservation agent, or by a method in which the reservation agent forms a queue for a processing device group having a similar function. Both methods,
Reservation agents can change the order of the queue according to their priority.

Product agents 31, 32, 33, 34
Has the following functions: Has priority. It has order information such as delivery date and product information such as serial number. It has a product production procedure and reserves and selects necessary equipment agents according to the procedure. Along with the movement of the product to the processing device, the product moves on the network to the control device having the corresponding device agent. Collect and manage production history. Messaging with other product agents. Regarding the production order, the following message communication is performed.・ Inquire the priority. Inquire whether the production procedure is the same. Alternatively, agents having the same production procedure may be searched for by broadcast communication. Negotiate between product agents, such as changing reservations and changing mappings with products.

FIG. 5 is a block diagram for explaining an example of the detailed structure of the product agent shown in FIG. In the product agent 3n, the communication unit 301 performs communication between the product agents, communication between the product agent and the device agent, and the like. The device selecting means 302 selects a processing device required in the production procedure. The operation command storage means 303 stores an operation command given to the processing apparatus in a format suitable for reading on the control device side.

The processing request means 304 requests the processing apparatus to perform processing. The processing request is performed by reading an operation command corresponding to the requested operation from the operation command storage unit 303 and providing the read operation command to the device agent.
The processing history management unit 305 manages a processing history for a product. The next destination determining means 306 determines the next destination of the agent. The information management unit 307 manages product information such as order information such as priority and delivery date, and serial number.

The operation of the embodiment shown in FIG. 4 will be described. FIG.
It is an example of a reservation queue provided for each processing device. In FIG. 6, the product agent searches for and reserves a processing device having a necessary function in the procedure following the current processing. It is the reservation agent, not the product agent itself, that is in the reservation queue. For example, the product agent 34 determines that the corresponding product is being processed by the processing device A, dynamically selects a processing device having the necessary function b in the following procedure, selects the processing device B, and selects the processing device B on the corresponding control device. Has been reserved in the queue QB. Further, the product agent 34 has a medium priority and holds the production history R4 up to the present.

FIG. 7 shows the operation when a high-priority product agent 36 is entered in FIG. When a high-priority product agent is input, the order of production is changed in order to precede production by a high-priority product agent. In FIG. 7, the order of production is changed in the following two ways.

The order of reservation of the product agent is changed. This is the process N1 in FIG. For example, in FIG. 6, by replacing the order of reservation of the product agent 36 having the priority “high” with the product agent 35 having the priority “low” which has been placed in the queue QA of the processing apparatus A, the product agent 36 is changed. Processing is performed first.

The product agent itself is replaced. This is the processing N3, N5 in FIG. By changing the correspondence between product agents and products, overtaking can be achieved. For example, when the substance of the product agent is not changed, the exchange between the product agents is realized by exchanging the production procedure and the product information while leaving the production history and the processing device reservation. For example, in FIG. 6, by associating the product agent with the product between the product agent 36 with the priority “high” and the product agent 35 with the priority “low”, the product agent 36
Processing is performed first. For products with advanced processing,
If the production procedure is the same up to the stage where processing is progressing,
Product agents may be exchanged.

The above two methods can be combined depending on the arrangement of equipment and the way of giving priority to the production system. In a production system with an agent installed, products can be transported freely to dynamically selected processing equipment.However, even in the case of equipment such as a belt conveyor where products cannot be overtaken, overtaking by replacing product agents themselves is not possible. It is valid. When the difference between the priorities is small, only the reservation order of the processing apparatuses may be changed without passing.

In the case of overtaking, the product may be searched from the reservation queue of the selected processing apparatus as shown at N2 in FIG. 7 and individually contacted with the product agent, or the product to be replaced by broadcast communication as at N4. You can also find agents.

In FIG. 4, product agents 31 to 3
High-priority product agent 3 with the same procedure as 4
When 6 (the product corresponding to the product agent 36 is assumed to be 76) is overtaken, the product agent 36 corresponds to the product 71 and the product agent 34 corresponds to the product 76.

FIG. 8 is a block diagram of another embodiment of the present invention. The product agents MX and MY have a message communication function, and perform processing while transmitting and receiving messages. Product agents MX and MY are recipes RX and R
A reservation agent for selecting and reserving a necessary processing device can be created for each processing procedure of Y. In the example of the figure, the product agent MX is the reservation agent x-1, x-
, X-3..., And the product agent MY creates reservation agents y-1, y-2.

Here, the reservation agent has the following information. A unit for reserving a partial processing device of a recipe, and is usually one line of the recipe. The production procedure described in the recipe is not a command unique to the processing device, but an operation that can be commonly interpreted within the device group. An apparatus group is a set of processing apparatuses having the same function. In the example of FIG. 8, the processing devices A1 and A2 belong to the device group A, the processing device B1 belongs to the device group B, and the processing devices C1 and C2 belong to the device group C, respectively. Processing equipment A1, A2, B1, C
1 and C2 are the device agents 4A1 and 4A, respectively.
2,4 B1, 4C1, and 4C2.

A candidate list of processing apparatuses that can execute the processing apparatus candidates is held. This list is an answer when a recipe using a multicast function or the like is thrown to an apparatus group, or information on a specific processing apparatus (for example, an identifier of an apparatus agent) specified in advance in the recipe or the like. This list is sorted in the order that you want to use it, both inside and outside the booking agent. It is updated as needed when a processing device is added.

In the example of FIG. 8, assuming that the product agent MY is scheduled and the processing device to be used is determined in advance, the reservation agent y-1 corresponding to the first line of the recipe RY is the processing device of the scheduling result. It has only C2 as a candidate and does not search for other candidates unless necessary. Therefore, the reservation agent y-1 makes a reservation if the processing device C2 is vacant when the reservation order comes to itself, and gives the reservation order to the subsequent reservation agent if it is not vacant. On the other hand, the reservation agent x-3,
A plurality of processing apparatuses C1 and C2 capable of executing the third line of the recipe RX of the product agent MX are provided as a candidate list.

Although the data is not essential for the expected processing time,
With the information, the processing device can be selected more efficiently. First, the expected maximum machining time is set. Also, when the information on the device group is thrown, if the estimated time of each processing device for the processing can be obtained, it is stored together with the information on.

Pointer to product agent This is a pointer for communicating with the product agent who owns the reservation. The reservation agent can inquire through the product agent about his / her previous reservation status (for example, the scheduled time until the work comes to the processing).

Each reservation agent is an alter ego of a product agent, and is arranged in a queue provided in the device group ahead of processing. Here, how far in advance the reservation agent is created depends on the application, such as up to a certain time ahead, up to a recipe at a certain destination, and all the recipes.

While the product agent moves to the control device where the device agent is located in response to the product (work), the reservation agent has a function to move to the place where the queue is located in advance. The arrangement order is a first-come-first-served order in consideration of the priority of the product agent, and it is possible to change this order in response to messages from the reservation agents and from outside. It also has a mechanism to propagate messages in queue order.

The device group is a group of processing devices having the same function, and has a group communication function or a multicast function for sending a message to a device agent belonging to a certain device group. An equipment group is a classification of processing equipment of the same type.Even processing equipment with the same function has different processing times, and a recipe can only be processed by some of the processing equipment in the equipment group. is there.

Upon receiving a part of the recipe, the device agent can answer whether or not the device is a processing device capable of executing the recipe and the expected processing time. The number of product agents that can simultaneously occupy the device agent is fixed and usually one. The device agent notifies the reservation agent waiting at the head of the queue of the device group to which the processing device becomes free when the processing device becomes free.

FIG. 9 is a block diagram for explaining an example of the detailed structure of the reservation agent shown in FIG. In the reservation agent 90, the communication means 91 performs communication between the reservation agents, communication between the reservation agent and the product agent, communication between the reservation agent and the device agent, and the like. The information storage unit 92 stores information such as a part of a recipe, a candidate for a processing device, an estimated processing time, a pointer to a product agent, and the like. The destination determining means 93 determines the destination of the reservation agent. The reservation means 94 reserves a processing device for the device group.

The operation of the embodiment shown in FIG. 9 will be described. FIG. 10 is a diagram showing an example of reservation agents arranged in a queue. The reservation agents in the queue for each device group have a right to select the processing device in the order of arrangement. The arrangement order is not a simple first-come-first-served basis but follows a priority or the like. In the example of FIG. 10, there is a right to select a processing device in the order of the reservation agents y-1, x-3, z-1. If the product corresponding to the appointment agent y-1 at the head is still processing the previous product, it will not be used immediately even if the processing device is available.
The recruitment requirement P1 of the vacant processing device C1 can be transmitted as a message to the next reservation agent x-3. At this time, in addition to the processing device name, the reservation agent can add the following conditions to the recruitment requirements.

When the free time reservation agent can obtain the expected processing time, the time until the corresponding product arrives is set as the free time, and the processing device can be yielded for the product whose processing is completed within that time. If the concept of the priority time of the product agent is not obtained, the priority of the corresponding product agent is added to prevent the processing agent from being used first by the product agent of lower priority.

If the processing apparatus is not in the processing apparatus candidate list, it is unconditionally passed to the next reservation agent. The reservation agent that matches the recruitment requirements issues an exclusive right request to the device agent, informs its own product agent that the exclusive right of the processing device has been acquired, and can request the processing.

FIG. 11 shows the operation when the product agent generates a reservation agent for selecting and reserving a required processing device for each processing procedure, and the reservation agent is queued in the device group.

The agent changes its behavior depending on its own internal state and the message received. The candidate list of the processing apparatuses searched in the above is arranged in the order of use based on a predetermined criterion. When the next message is received, the reservation agent further changes the order as follows.

(1-1) Failure of the processing apparatus If the candidate is in his / her own, the candidate is deleted from the candidate. If there are no more candidates, another search in the apparatus group enables another processing apparatus to be used even if a specific processing apparatus scheduled in advance breaks down, for example. (1-2) Addition of a processing device Throw a recipe to a new device agent and add it to the list if it can be processed. (1-3) Others A change in a policy for arranging in a desired order may be received as a message. It is also possible to directly request the rearrangement and delete the candidates.

Even if the order of the reservation agents in the queue (process S3 in FIG. 11) is initially arranged in the first-come-first-served order according to the priority of the product agent, for example, communication between the reservation agents and messages from other modules May be changed on the way. For example, at the time of processing S4, even if the priority is the same, the reservation of the product agent whose delivery date is close can be made first.

The process S5 in FIG. 11 is a state in which the exclusive right of the processing apparatus has been acquired or not, but the execution of the recipe assigned by the reservation agent has not yet come. In this state, the processing when the processing apparatus is vacant is shown in FIG.
Shown in

In FIG. 12, if the immediately preceding machining is not completed, the machining device is not used immediately yet, so even if it is a candidate machining device, an exclusive right request is issued for the time being (process T6 in FIG. 12). Then, the conditions of the recruitment essential message are set so that they may be used earlier than the user (process T7 in FIG. 12). The later-listed reservation agents satisfying this condition negotiate with the reservation agent that has temporarily acquired the exclusive right. Even if the reservation agent has already acquired the exclusive right of the processing device, if a more preferable processing device is available among the candidates (process T8 in FIG. 12), the recruitment requirement is acquired by oneself. Sometimes it is rewritten to the processing device.
