DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of the manufacturing industry simulator. This manufacturing industry simulator includes a production simulator 1 that sets processing conditions such as a processing sequence for processing of a processing device, a transfer device, and a worker, and simulates a flow of product manufacturing. The production simulator 1 is provided with a market simulator 2 for issuing an order request for a product price and a delivery date.

The production simulator 1 has a structure including a factory model 10 described as a data model (model unit) of a processing apparatus and the like, and an engine unit 11 as a program model for changing the state of the factory model 10. ing.

The factory model 10 generally includes a physical model 12 that describes a processing device, a transport device, an operator, a storage device (location), and the like, and starts processing such as processing order and processing time of a product or resources required for processing. It has each function of the logical model 13 that describes a stop condition.

The factory model 10 has a data module as a data module, which is based on initial funding, and increases or decreases the material cost and the sales amount of the product in accordance with the order request in accordance with the progress of the simulation of the product manufacturing flow. Has a function of a fund model 14 for grasping the situation.

In other words, the fund model 14 treats funds as resources necessary for manufacturing when executing a simulation. At the start of the simulation, a fixed amount is held as an initial fund to simulate the flow of product manufacturing. As a result, when consuming parts for product manufacturing, etc., it consumes funds as material costs, and also consumes personnel expenses from the funds according to the number of workers and their working hours, and also consumes the expenses from the funds, and If the production progresses, the product is completed, and if there is demand from the market simulator 2, the product is added to the fund as sales and has a function of monitoring the amount of the fund.

The fund model 14 executes simulations for a production line having a layout in which a combination of a processing device and a transport device, a work route of an operator and the like are set, that is, a production line composed of the physical model 12 and the logical model 13. In addition, it has a function of monitoring the amount of funds and simulating a profit in a predetermined period determined by the demand amount of the product received from the market simulator 2, for example, a period in which the demand amount is large.

Further, the fund model 14 calculates a sales curve for the initial fund as shown in FIG. 3 from the execution result of the simulation for the production line composed of the physical model 12 and the logical model 13, and calculates the sales curve from the initial fund. It has a function of obtaining debt from the cost at each preset investment timing of equipment, and calculating the behavior of profit from the sales and debt.

The production simulator 1 has a fund model 1
In the execution of step 4, each interface with the market simulator 2 is provided as shown in FIG. That is,
An interface of delivery date and selling price reply for answering the delivery date and selling price of the product from the market simulator 2, an interface of order receiving for confirming the order in response to the ordering request for the product, delivering the product to the market simulator 2 and receiving the receipt. Has a delivery interface.

On the other hand, the market simulator 2 has a structure including a market model 20 which is a data module, and an engine unit 21 as a program module for receiving a time according to the market model 20 and an order quantity or delivery. It has a function of ordering the production simulator 1 based on the price and delivery date of the product.

The order quantity for the price and delivery date of the product is a function of time corresponding to the life cycle of the product based on, for example, the image of the market model 20 shown in FIG.

That is, the market model 20 shown in FIG.
The relationship between the delivery date, the order quantity, and the selling price is shown. For example, if the delivery date is short, the order quantity increases and the selling price increases, and if the delivery date increases, the order quantity decreases and the selling price decreases.

If the order quantity is small, the delivery date will be short and the selling price will decrease, and if the order quantity is large, the delivery date will be long and the selling price will increase. If the selling price decreases, the delivery time will increase and the order volume will increase, and if the selling price increases,
Shorter delivery times and smaller order volumes.

The market simulator 2 holds data indicating the trend of the demand in the market of each product as shown in FIG. 5, for example. That is, the demand of the product A gradually increases from the start of sales, and gradually decreases after the demand peak.

The product B is an improved product of the product A. The product B starts selling when the demand peak of the product A has passed, and the demand decreases after the peak.
The product C is an improved product of the product B. The product C starts to be sold after the demand peak of the product B, and the demand decreases after the peak.

Therefore, the market simulator 2 has a function of placing an order for the production simulator 1 in accordance with the trend of the demand in the market. The market simulator 2 has interfaces with the production simulator 1 as shown in FIG.

That is, an interface for requesting a delivery date and a sale price for inquiring the delivery date and sale price of the product to the production simulator 1 and obtaining an answer, an interface for ordering the product for the production simulator 1, and a product for the order. It has an interface for delivery received from the production simulator 1.

Next, the operation of the above-configured device will be described. The production simulator 1 has a factory model 10
In the physical model 12, a processing line, a transfer device, a worker, a storage device (location), and the like are described to create a preset production line, for example, a production line for manufacturing the product A, and The logical model 13 describes processing start / stop conditions such as the processing order and processing time of a product or resources required for processing.

When the production line and its conditions are described in this manner, the engine unit 11 of the production simulator 1 changes the state of the factory model 10, that is, the production line for producing the product A in accordance with the conditions such as the processing order and the processing time. Change the state and execute the simulation.

By executing this simulation, the production quantity, processing period,
General indices such as the amount of work in progress, the operation rate of the manufacturing apparatus, and the time worked by the worker are obtained.

On the other hand, the market simulator 2 requests the delivery date and selling price of the product A according to the market model 20 shown in FIG. As shown in FIG. 2, the production simulator 1 receives the delivery date and selling price request of the product A, and sends the delivery date and selling price to the market simulator 2.

Next, the market simulator 2 requests the production simulator 1 to order the product A. The production simulator 1 returns an order confirmation to the market simulator 2 in response to the order request for the product A.

Subsequently, when the production simulator 1 delivers the product A, the market simulator 2 returns a receipt for the delivery of the product A. Thus, the production simulator 1
A request for ordering and delivery of the product A is made with the market simulator 2, and during this simulation, the fund model 14 holds a fixed amount as an initial fund at the start of the simulation, and simulates the flow of production of the product A. With the progress of the project, the company consumes funds as material costs when consuming product manufacturing parts, etc., and also consumes personnel expenses from the funds according to the number of workers and their working hours, and also consumes the expenses from the funds. If the production progresses, the product is completed, and there is a demand from the market simulator 2, the product is added to the fund as sales and the amount of the fund is monitored.

That is, the production simulator 1 simulates the production of the product A according to the order from the market simulator 2, subtracts the price required for the production from the fund, and adds the sales according to the delivery to the fund.

Thus, the production simulator 1 monitors the amount of funds in addition to the evaluation of the production quantity, the processing period, the work in progress, the operation rate of the manufacturing equipment, the time worked by the worker, etc. for the production line, and I understand the state.

Further, as described above, in the production simulator 1, an order request for the product A is sent to and from the market simulator 2, the product is delivered, and during the simulation of the production line of the product A, the fund model 14 determines the amount of the fund. It monitors and simulates a profit within a predetermined period determined by the demand amount of the product A received from the market simulator 2, for example, a period T shown in FIG.

Further, the fund model 14 calculates a sales curve for the initial fund as shown in FIG. 3 from the execution results of the above simulation, and borrows the cost from the cost at each preset investment timing of the facility from the initial fund. From these sales and debts.

As described above, in one embodiment,
For example, a production simulator 1 that sets processing conditions such as a processing sequence for the operation of the processing apparatus and the work of a worker to simulate, for example, the flow of production of the product A, and a price of the product A in a preset market trend. And a market simulator 2 that issues an order request for a delivery date to the production simulator 1. Based on the initial funds in the production simulator 1, material costs and order requests are made in accordance with the progress of the simulation of the production flow of the product A. With the fund model 14 that grasps the financial behavior by increasing or decreasing the sales amount of the corresponding product, the required production volume can be easily predicted and presented, and the production behavior can be simulated by automatically incorporating the premise, In addition, it is possible to provide information that grasps the financial behavior, which is the purpose of the manufacturing industry, and can easily determine how much the financial profit, which is the original purpose of the manufacturing industry, has been achieved. .

Therefore, by grasping the behavior of funds, the amount of profit in the manufacturing industry can be grasped, and the market model 20
By performing production simulations in conjunction with this, it is possible to reproduce a state closer to reality and obtain effective information when planning equipment and workers.

Further, since the flow of funds can be grasped continuously over a medium / long term, effective information for management judgment can be obtained. Further, it is possible to simulate the profit in a predetermined period determined by the demand amount of the product A, for example, the period T in which the demand amount of the product A is large as shown in FIG. By simulating the profit in a period in which the demand amount is large, the profit in the production line for manufacturing the product B can be found.

Therefore, for example, it is possible to determine whether the layout of the processing device and the transport device in the production line for manufacturing the product A is optimal from the viewpoint of profit, and to determine the layout of the production line to optimize the layout from the viewpoint of profit. Information can be obtained.

On the other hand, the fund model 14 calculates a sales curve for the initial fund as shown in FIG. 3 and obtains a debt from the cost at each preset investment timing of the facility from the initial fund. Information on how to change the timing of capital investment and the amount of the capital investment to the optimal timing from the simulation results of production, that is, to determine whether or not it is the optimal expansion schedule in business operation You can get the information of management so that the profit is the most profitable.

Accordingly, it is possible to obtain the timing of capital investment commensurate with the sales amount and to steadily expand the business in the manufacturing industry. The present invention is not limited to the above-described embodiment, but may be modified as follows.

For example, the market model 20 of the market simulator 2 has been described on the premise that the market model 20 holds data in the form of data. However, the market model 20 has a structure in which one market simulator is connected by the same interface as a plurality of production simulators. Is also good.

In this case, another production simulator can be simulated assuming that it is another competing company.
By setting up a market simulator that orders many products from multiple suppliers to meet the needs, it is possible to simulate the rise and fall of the entire industry, not just one manufacturing industry.

As a special case, if the market of the product (product) to be applied is considered to be constantly stable or stable in comparison with the prediction accuracy, the market may be simulated. No state change occurs.

Therefore, in such a case, if a financial evaluation index is included in the analysis function, the same information can be obtained by operating a general production simulator with the condition of the production amount fixed.

As described above, according to the present invention, it is possible to provide a manufacturing simulator capable of simulating the production behavior and judging the monetary profit by grasping the monetary behavior which is the purpose of the manufacturing industry.

Further, according to the present invention, it is possible to provide a manufacturing simulator which can grasp the financial behavior which is the purpose of the manufacturing industry and grasp the profit of the product within a predetermined period. Further, according to the present invention, the manufacturing simulator which can change the timing of the capital investment and the amount of the capital investment to the optimum timing from the simulation result of the production, and can obtain the most profitable management information Can be provided.
