Abstract

PROBLEM TO BE SOLVED: To solve the problem that a worker in the conventional production processes can not properly perform work management since the worker does not know a true target time to make up delay of the production processes. SOLUTION: A vehicle production management part 30 first sets scheduled time of start of construction and scheduled time of completion of the respective processes for the respective vehicles based on vehicle information of vehicles which is scheduled to be produced. The respective processes transmit result time of start of construction of the processes in which the construction is actually started for the respective vehicles to the vehicle production managing part 30 and the vehicle production managing part 30 calculates target time of completion of the processes to complete the respective processes for the respective vehicles based on the result time of start of the construction. The worker of the respective processes can exactly grasp by what time works for the various vehicles is performed by a fact that the scheduled time of start of construction of the processes, the scheduled time of completion of the processes and the target time of completion of the processes for the respective vehicles are outputted to the respective processes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling a process of producing a product.

[0002]

2. Description of the Related Art In a vehicle production plant, a scheduled passage time of a detailed process is calculated for each vehicle in order to comply with the delivery date of the production vehicle. However, in actual production, progress may be delayed or advanced. In case of delay,
It is necessary to detect it as early as possible and recover the delay by rushing the work of the subsequent process. In the conventional method, the scheduled passage time of each process until the final inspection process is completed is calculated before the production of the body process for making the body portion is started. The scheduled passage time is compared with the time when each vehicle actually passed each process, and if there is a delay, the worker of each process is urged to recover the delay.

[0003]

When a large delay occurs in the progress of vehicle production due to equipment failure or other reasons, it is difficult to recover the delay only in the process immediately after. Therefore, it is necessary to gradually recover the delay in each process up to the inspection process. In this case, the scheduled passage time initially set does not make sense, and the time to complete each process becomes unclear. For this reason, the worker does not know the true target time for catching up the delay, so that the work management cannot be properly performed.

Therefore, an object of the present invention is to provide a production process control device which can solve the above problems.

[0005]

That is, the present invention is a production process management apparatus for managing a process for producing a product through a plurality of element processes, and a scheduled process start time for starting each element process for a product. , And a means for setting a scheduled process completion time for completing each element process, a means for acquiring a process start actual time when each element process is actually started for the product, and a process start actual time is more than the process start scheduled time. When there is an element process that is delayed, a means for setting a process completion target time for completing the element process, and a means for outputting the scheduled process start time and the process completion target time to each element process.

Here, the element processes include, for example, a vehicle production process, a body process, a painting process, an outfitting process, and an inspection process.

The process start target time is the process start actual time,
It is calculated from the time normally required for the element process and the time during which the element process can be shortened.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described through embodiments of the invention.

FIG. 1 is a block diagram showing the configuration of a production process control apparatus 10 according to an embodiment of the present invention. The vehicle production process of this embodiment includes a body process, a painting process, an outfitting process, and an inspection process, and the vehicle production process proceeds in this order. The production process management device 10 manages the delivery date and the progress status in each process.

The production process management device 10 has a vehicle production information reception unit 20, a vehicle production management unit 30, a vehicle production information database 40, a vehicle production information output unit 50, and a vehicle passage information reception unit 60.

The vehicle production information receiving unit 20 receives vehicle information including a vehicle ID for identifying the vehicle and information regarding specifications such as vehicle type and color of the vehicle scheduled to be produced in this production process. The received vehicle information is sent to the next vehicle production management unit 30.

The vehicle production management unit 30 creates a production plan for each vehicle based on the vehicle information. As a result, for each vehicle, the scheduled loading time to be loaded into each process, the scheduled shipping time to carry out the work in each process, and the like are set.
The scheduled time set by the vehicle production management unit 30 is written in the vehicle production information database 40. In addition, when the vehicle production management unit 30 receives the time when each vehicle actually passed each process from the vehicle passage information reception unit 60 described later, the vehicle production management unit 30 recalculates the scheduled passage time of the subsequent processes. , Write in the vehicle production information database 40. Details of the production planning of each vehicle by the vehicle production management unit 30 will be described later.

The vehicle production information database 40 stores a process schedule table in which scheduled times and the like are stored for each vehicle, and a total table in which delay times for each process are totaled.

The vehicle production information output unit 50 reads out the scheduled delivery time of each process from the vehicle production information database 40 and sends it to each process.

In each process, the scheduled time of introduction for each vehicle,
The scheduled delivery time, the actual delivery time, the targeted delivery time (1), the targeted delivery time (2), etc. are output to a delay display plate, a printer, etc., to notify the operator of the production delay status of the vehicle.

In each step, when the work of each vehicle is completed, the information for identifying the vehicle, the type of the step, and the time when the step is completed (passed) are used as vehicle passage information. It is transmitted to the vehicle passage information reception unit 60.

The vehicle passage information receiving section 60 is provided with
The process start actual time when the construction is actually started and the process completion actual time when the construction is actually completed are received, and the received process start actual time and the process completion actual time are transmitted to the vehicle production management unit 30.

The production of the production plan in the vehicle production management unit 30 will be described below.

FIG. 2 shows an example of the process schedule table 100 included in the vehicle production information database 40. With reference to the process schedule table 100, the vehicle production management unit 30
Production control in. Process schedule table 100
Is associated with the vehicle ID, the process name, the standard process passage time, the scheduled process start time, the scheduled process completion time, the process start actual time, the process complete actual time, the process completion target time (1),
And the process completion target time (2) is stored.

Here, the "vehicle ID" is information for identifying the vehicle. The “process name” is the name of each process. The “process passing standard time” is the standard time required for the work of each process (the standard time required for passing through the process). The standard process passage time varies depending on the specifications and is preset for each specification. The "scheduled process start time" is a scheduled time when a predetermined process is started for each vehicle. The “process completion scheduled time” is a scheduled time when the work in a predetermined process is completed for each vehicle. The scheduled process completion time is obtained by adding the scheduled process start time to the standard process passage time for the process. The “process start actual time” is the time when a predetermined process is actually started for each vehicle. The “process completion record time” is the time when a predetermined process is actually completed for each vehicle. The “process completion target time (1)” is a time obtained by adding the “process passing standard time” of the process to the “process start actual time” of the predetermined process. The “process completion target time (2)” is a time set to recover the delay for each process.

First, with respect to the body process, which is the first process of the production process, reference is made to the scheduled start time of another vehicle (considering the availability of the body process), and the process start of the body process for the vehicle is scheduled. The time is set. Subsequently, when the work in the body process is performed according to the specifications included in the vehicle information, the predetermined process passage standard time is added to the process start scheduled time to obtain the process completion scheduled time for the body process.

For the coating process subsequent to the body process, the scheduled process start time for the body process is set after the scheduled process completion time of the body process in consideration of the availability of the coating process. Hereinafter, similarly, a scheduled process start time and a scheduled process completion time for each process are set.

In the example of the painting process shown in FIG. 2, the scheduled process start time is set to 13:00. Vehicle ID (000
Regarding 1), the process passage standard time (here, 3 when the body process is performed according to the specifications included in the vehicle information)
The scheduled process completion time (16:00) is set by adding (time) to the scheduled process start time (13:00).

When the actual process start time (13:30 in this case) at which the coating process is actually started is acquired, the process passing standard time is added to this to obtain the process completion target time (1) ( 16:30) is set. The process completion target time (1) is a target time when the coating process is produced in the process passing standard time. However, if this is left as it is, the process completion target time (2) is set separately in order to recover the delay.
The process completion target time (2) is determined for each process based on the time when the delay can be recovered by cutting down the construction time. For example, in the case of the coating process, if it is possible to recover the delay of 15 minutes, the process completion target time (1) (16:30) to 15
The time when the minutes are subtracted (16:15) becomes the process completion target time (2). Incidentally, the delay that could not be recovered in the painting process is adjusted in time for the final delivery date by sequentially recovering it in the subsequent outfitting process and inspection process.

In this way, when the process start actual time in the coating process is delayed from the process start scheduled time, the process completion target time (2) is set based on the process start actual time. This process completion target time (2) is transmitted to the painting process and output, etc., so that the worker of the painting process can easily set the process completion target time (2) according to the progress status of the actual production process. It is possible to recognize, and it is possible to surely know how many minutes of the delay in the production process should be recovered in the own process.

Further, the vehicle production management unit 30 refers to the process schedule table 100 obtained for each vehicle for each process, collects the production delay situation, and records it in the vehicle production information database 40. FIG. 3 is an example of the aggregation table 110 of the production delay situation. This tabulation table 11
For a specific process, 0 is a table in which the delay time caused in the production process of the process and the number of corresponding vehicles are associated with each other. The delay time caused in the construction process of the process is, for example, the process start actual time is 13:30, the process completion target time (2) is 16:15, and the process complete actual time is 1
If it was 6:30, the delay time would be 15 minutes.

As described above, by accumulating the results of each production process, it is possible to grasp what kind of delay has occurred for each process and utilize it for production management.

[0028]

As is apparent from the above description, according to the present invention, even if the time when each production process is started is behind the scheduled time, the worker of each production process is Can grasp the goal of when to finish the work of.
