Description

Vehicle withdrawal method of painted body automatic warehouse {METHOD FOR TAKING OUT VEHICLES OF PAINTED BODY STORAGE}

The present invention relates to a vehicle withdrawal method of an automatic painting vehicle body warehouse, and more particularly, a PULL method having an algorithm including a sequence keeping concept while operating an existing production method as it is. In order to improve the efficiency of line management of the design factory, the vehicle withdrawal method of the automatic painting warehouse body can be improved by changing the software information of the vehicle flowing in the factory according to the production plan to artificially change the order. It is about.

In general, automakers use a variety of processes from the selection of materials to the mass production of products to produce a finished car.These processes are designed to produce more products in a shorter time by adopting an automation system in line with the trend of factory automation. Efforts are underway, and a number of efforts are under way to make efficient use of the facility.

Recently, the production line system is becoming more and more complex due to securing competitiveness in domestic and overseas markets and increasing specifications for various purchase desires of customers. At this point, production information systems that can respond to complex production lines in a more effective and scientific way are more urgently needed.

In particular, the automotive plant has a complex production structure and numerous component vendors face the important task of delivering components to assembly plants in a limited time. In addition, according to this production method, it also has inventory

As part of the production method based on this, as shown in FIG. 1, the production order is determined based on the initial design factory, and according to the order, the parts are put in order from the car body factory to the coating factory, and then the design factory is input. In the former, painted body storage (PBS; automatic warehouse serving as a buffer between the design factory and the paint shop; hereinafter referred to as PBS), the PUSH method to match the initial sequence and the wrong sequence, ie push As a betting method, it takes a vehicle withdrawal algorithm that is designed considering the work leveling of the design factory.

As shown in FIG. 2, the PUSH algorithm divides the vehicle inside the PBS into a list of prohibited vehicles (Hold_List) and a list of available vehicles (Available_List).

Here, the vehicle in the banned vehicle list (Hold_List) is a list of vehicles that should not be withdrawn due to lack of parts of the design factory, and the list of available vehicles (Available_List) refers to the list of vehicles that can be withdrawn.

Where a vehicle belongs to these two lists is determined by the holding condition.

Here, the holding condition is that the production is stopped when the vehicle equipped with the corresponding part is put into the design factory due to the lack of a specific part of the design factory. Therefore, the vehicle with the corresponding component is prohibited in advance to the design factory. Conditions (eg, prohibition of vehicle withdrawal, for example, specification 1 = AAA).

In order to select a withdrawal vehicle from the PBS, a constraint condition, an exception condition, and a job chasing method condition among the vehicles in the inputable vehicle list (Available_List) are called GCM conditions. ), The vehicle that best meets all conditions is selected and registered in the withdrawal vehicle list (TDL_List) for final withdrawal.

In other words, a standardized formula (Violation, Leveling) is created to select the optimal withdrawal vehicle for constraints, exceptions, and leveling conditions, and is put in the formula for each vehicle in the list of available vehicles (Available_List). After calculating the total list (Calculated_List), the totals are ordered in descending order, and once again, the first vehicle is selected as the next withdrawal vehicle. . If there are several vehicles of the same value, the PBS entry order is chosen in the order of rapidity.

Here, the constraints are conditions for maintaining the specific vehicle more than a predetermined interval or continuous input due to the constraints of the production environment of the design factory (for example, absolute maintenance of more than 3 intervals between the vehicle, the specification 2 = BBB, etc.) That is, the exceptional condition refers to a condition for changing the assembly specification (for example, Body No = EAF 123456 vehicle emergency withdrawal, etc.) and a condition for emergency application to the design factory for a special purpose vehicle or other reasons. Refers to the conditions for leveling the operator's factory components to prevent temporary component shortages, as well as leveling worker workloads (eg, vehicle leveling with specification 3 = CCC, importance 200, etc.).

As described above, the vehicle withdrawing method of the automatic vehicle body of the painting body considering only the work leveling in the conventional PUSH method will be described in more detail with reference to FIG. 3. First, a condition violation score can be inputted using constraints, exception conditions, and leveling conditions. The vehicles in the list (Available_List) are accumulated in the total list (Calculated_List), respectively (S10).

Next, the vehicles are ordered in descending order of the total violation score (S20).

Subsequently, the vehicle with the lowest total violation score is selected (S30).

At this time, if it is determined whether there is a selected vehicle (S40), if the condition is not satisfied, after the time delay step (S50) for a set time, and returns to the first step (S10), if the condition is satisfied, the selected vehicle It is determined whether this is one (S60).

In this case, if there is only one selected vehicle, it is determined whether the selected vehicle violates the absolute compliance requirements under the constraints (S70). If the selected vehicle is not one, the vehicle having the smallest PBS Seq. In operation S80, it is determined whether the selected vehicle violates the absolute compliance matters in the constraint condition.

As such, if the selected vehicle violates in the step S70 of determining whether the violation of the absolute compliance on the constraint condition, after deleting the vehicle from the total list (Calculated_List) (S90), the total cumulative violation score is the most. The process returns to step S30 of selecting a small vehicle.

If the selected vehicle does not violate at step S80 of determining whether the selected vehicle violates an absolute compliance item on the constraint condition, the corresponding vehicle may be registered in the withdrawal vehicle list TDL_List (S99) and finally withdrawn.

However, the PBS vehicle withdrawal method, which is composed of these algorithms, is applied to the existing PUSH method to determine the withdrawal vehicle considering only work leveling. Based on the production constraints considering the environment of the car body, painting, and design factory in the initial production planning stage Although the order of production is determined by the order of production, the vehicles are put in order in the initial process, but in fact, during the production flow process of the body, the painting and the design factory, the vehicle is unloaded due to quality problems (during production, due to quality problems, etc.) Getting out of the line) The order of the vehicle, such as the correction work and the standby buffer, is confusing, and the correction work is supplemented by the PBS to the design factory before the design factory. Due to the difference of actual vehicles, the supplier's synchronized production could not be produced, resulting in the burden of parts inventory of the company. Secondly, logistics costs, investment costs, and labor costs will increase due to the operation of internal parts warehouses. Third, additional IT investment costs will be incurred for system supplement and production management operations due to the incorrect order of the orders. In the case of long-term standby cars caused by quality problems, the company has problems such as heightened customer dissatisfaction and deterioration of company image and credibility due to delayed acquisition of customers.

Therefore, in order to overcome the problem of the PUSH method, which only considers work leveling, as in the conventional PBS vehicle withdrawal method as described above, the PULL method is recently applied simultaneously.

As shown in FIG. 4, the PULL method is an algorithm including a sequence keeping concept while operating an existing production method as it is, and software information of a vehicle flowing in a factory according to a production plan It is a production method that artificially changes the order by replacing. In other words, by continuously tracking the flow of the production sequence information by changing the information of the vehicle in a specific process it is possible to obtain the effect of returning the sequence of the vehicle.

Here, the sequence keeping ratio (SKR) mode for the PBS withdrawal mode for the sequence keeping applied to the PULL method, when the status of the PBS is not possible to maintain the order temporarily, PBS withdrawal mode considering only Goal Chasing Method (GCM) is referred to as GCM (Goal Chasing Method) mode.

Therefore, the present invention was created to apply the withdrawal algorithm according to the order maintaining concept so that the PBS can be operated by applying the PULL method, and an object of the present invention is to maximize sequence keeping in the PBS. A vehicle that can be selected is selected from an In_Seq_List (that is, a list of vehicles that can be ordered among the vehicles in the PBS), and the vehicles that can be inserted between them (that is, satisfy the constraints) are ordered. It provides a vehicle withdrawal method of an automatic painted vehicle body warehouse that can exhaust the ordered vehicles as quickly as possible by finding and injecting them out of the vehicle list (Out_of_Seq_List), that is, a list of vehicles that cannot be maintained in the PBS. will be.

The vehicle withdrawal method of the automatic painting vehicle body warehouse according to the present invention for realizing the above object includes a vehicle that satisfies the holding conditions among the vehicles in the automatic vehicle body painting warehouse in the input prohibited vehicle list (Hold_List), and keeps the current input order. Including a vehicle which can be included in the ordered vehicle list (In_Seq_List) and a vehicle which cannot keep the order of the current input in the ordered vehicle list (Out_of_Seq_List); First, if it is determined whether there is a vehicle 1 having a number greater than the PBS inflow order number of the last maintained vehicle, the temporary variable (Found_Vehicle) is assigned to the vehicle and the predetermined chairman An order maintenance step (S100) for determining whether order maintenance is possible in a factory input order;

In the order maintaining step (S100), when there is no vehicle 1 having a number greater than the PBS incoming order number and thus cannot be kept out of a predetermined order, it is possible to replace the out of order vehicle and the specification that have been missed in the order. A vehicle specification replacement step (S200) of attempting to replace a specification of a corresponding vehicle by finding a vehicle in an automatic warehouse of a painting vehicle and replacing specification data and a temporary variable (Found_Vehicle) for the vehicle;

In the vehicle specification replacement attempt step (S200), when specification substitution is not possible, the vehicle having the same specification on the constraint condition as the out of order vehicle is found in the out of order vehicle list Out_of_Seq_List and the temporary variable (Found_Vehicle) for the corresponding vehicle. Attempt to replace the vehicle input attempt to replace the vehicle by giving a step (S300);

Following the order maintenance step (S100), vehicle specification replacement attempt step (S200), replacement vehicle input attempt step (S300), if there is a vehicle in the ordered vehicle list (Out_of_Seq_List), by using this batch processing of the ordered vehicle If a vehicle set (Delay_Vehicle_Set) is created and all vehicles are registered in the list of scheduled to-go vehicle list (TDL_List), and if the set for delayed vehicle batch processing (Delay_Vehicle_Set) cannot be created, all of the vehicles in the ordered vehicle list (Out_of_Seq_List) It is determined whether the constraints are violated in the order of the PBS inflow order number for the vehicle, and when the vehicle is not violated, the vehicle is registered in the insertion order vehicle insertion list (Insert_List) and all the vehicles in the insertion order vehicle insertion list (Insert_List) are withdrawn. A stepped-out vehicle exhaustion step (S400) of registering the scheduled vehicle list (TDL_List) to exhaust the ordered-drain vehicle as much as possible;

In the out of order vehicle exhausting step (S400), the vehicle does not exist in the out of order vehicle list (Out_of_Seq_List), or the vehicle is present in the out of order vehicle list (Out_of_Seq_List) through the out of order vehicle exhausted step (S400) It is determined whether the temporary variable (Found_Vehicle) for all the vehicles registered in the to-be-trailed vehicle list (TDL_List) has been granted, and if the temporary variable (Found_Vehicle) is given, the final to-be-told registered with the to-be-told vehicle list (TDL_List). Vehicle registration step (S500) is included.

BEST MODE Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 is a conceptual diagram of the PULL method when the vehicle is withdrawn from the automatic vehicle body painting (PBS) according to an embodiment of the present invention, Figure 5 is an embodiment of the present invention according to the order maintaining mode applied to the PULL method of FIG. 6 is a flowchart of a drawing algorithm according to an embodiment of the present invention in a process according to the order keeping mode of FIG. 5.

The vehicle withdrawal method of the automatic painting vehicle body warehouse according to an embodiment of the present invention, as shown in Figure 4, is an algorithm that includes the concept of maintaining the sequence (Sequence Keeping) while operating the existing production method, which is a production plan This is to apply to the PULL method, which is a production method that artificially changes the order by changing the information of vehicles flowing in the factory by software.

In other words, by continuously tracking the flow of the production sequence information by changing the information of the vehicle in a specific process it is possible to obtain the effect of returning the sequence of the vehicle.

As shown in FIG. 5, the sequence keeping ratio (SKR) mode, which is a basic concept of the present invention, includes vehicles that satisfy holding conditions among vehicles in a PBS in a hold_list, and the current insertion order. In the ordered vehicle list (In_Seq_List), a vehicle capable of keeping a can be included in the ordered vehicle list (Out_of_Seq_List).

Accordingly, a vehicle that can maximize sequence keeping is selected from the order vehicle list (In_Seq_List), and then a vehicle that can be injected between them (that is, satisfying a constraint) is out of sequence vehicle list (Out_of_Seq_List). Find as much as possible and put it in between. In other words, try to run out of order as soon as possible.

Referring to this series of algorithms in more detail with reference to FIG. 6, when the presence or absence of the vehicle 1 having a value greater than 1 is greater than the PBS Seq. In addition, by providing a temporary variable (Found_Vehicle) to the vehicle, it has a sequence maintenance step (S100) to determine whether the order can be maintained in the order of the predetermined design factory input.

In the order maintaining step (S100), when there is no vehicle 1 having a number greater than the PBS incoming order number and thus cannot be kept out of a predetermined order, it is possible to replace the out of order vehicle and the specification that have been missed in the order. By finding the vehicle in the PBS and replacing the specification data for the vehicle and granting a temporary variable (Found_Vehicle), the vehicle specification replacement attempt step S200 is attempted to replace the specification of the vehicle.

In the vehicle specification replacement attempt step (S200), when specification substitution is not possible, the vehicle having the same specification on the constraint condition as the out of order vehicle is found in the out of order vehicle list Out_of_Seq_List and the temporary variable (Found_Vehicle) for the corresponding vehicle. Proceed step (S300) of the replacement vehicle input attempts to replace the vehicle by giving a).

Subsequent to the order maintaining step (S100) or the vehicle specification replacement attempt step (S200) or the replacement vehicle input attempt step (S300), when there is a vehicle in the order droop vehicle list (Out_of_Seq_List), the ordered vehicle is collectively used using the vehicle. If a process set (Delay_Vehicle_Set) is created and all the vehicles are registered in the TDL_List to be withdrawn, and the set for processing the batched vehicle batch (Delay_Vehicle_Set) cannot be created, it is in the ordered vehicle list (Out_of_Seq_List). It is determined whether all the vehicles violate the constraints in the order of PBS insertion order number, and if the vehicle is not violated, the vehicle is registered in the insertion order vehicle Insert List (Insert_List), and then all vehicles in the insertion order vehicle insertion list (Insert_List) Registered vehicle withdrawal order (TDL_List) to exhaust the ordered vehicle to exhaust the ordered vehicle exhaustion step (S400) Ongoing.

In the out of order vehicle exhausting step (S400), the vehicle does not exist in the out of order vehicle list (Out_of_Seq_List), or the vehicle is present in the out of order vehicle list (Out_of_Seq_List) through the out of order vehicle exhausted step (S400) It is determined whether the temporary variable (Found_Vehicle) for all the vehicles registered in the to-be-trailed vehicle list (TDL_List) has been granted, and if the temporary variable (Found_Vehicle) is given, the final to-be-told registered with the to-be-told vehicle list (TDL_List). By proceeding the vehicle registration step (S500), the vehicle is withdrawn from the PBS in accordance with the concept of order maintenance.

Hereinafter, a detailed algorithm will be described for each step.

First, the order maintaining step (S100) finds a vehicle 1 that is one greater than the PBS Seq. No. number of the last ordered vehicle put into the PBS.

It is determined whether there is a vehicle 1 that is greater than 1 by the PBS Seq. No. number of the order-maintained vehicle last inputted from the step S110.

If it does not exist in the step (S120), proceeds to the vehicle specification replacement attempt step (S200), and if present in the step (S120), a temporary variable (Found_Vehicle = vehicle (1)) is assigned to the vehicle After that, the process proceeds to exhausting the sag vehicle (S400). (S130)

Here, the vehicle 1 having a larger number than the PBS incoming sequence number 1 means that the vehicle is immediately inserted after the last ordered vehicle that was last put into the PBS at the present time.

If the vehicle specification replacement attempt step (S200) does not exist in the order maintaining step (S100), the vehicle 1 having a larger number than the PBS entry order number 1 does not exist in the predetermined order, so that the order cannot be maintained. It is determined whether or not the alternative mode (S210).

In the step (S210), if it is not the specification replaceable mode, proceeds to the replacement vehicle input attempt step (S300), and in the case of the specification replaceable mode, the vehicle out of the predetermined order and the vehicle capable of specification replacement (4) ) Is found in the paint car body warehouse and replaces the specification data for the vehicle.

After the step S220, it is determined whether the specification replacement for the corresponding vehicle is successful. (S230)

In step S230, if it is determined that the specification replacement is not successful, the process proceeds to the replacement vehicle input attempt step S300. If it is determined that the specification replacement is successful, the temporary variable (Found_Vehicle = vehicle 4) is applied to the vehicle. (S240).

In the vehicle specification replacement attempt step S300, when the specification replacement is not possible in the vehicle specification replacement step S200, the vehicle 2 having the same specification on the constraint condition as the out of order vehicle may be disposed in the order vehicle. Search in the list Out_of_Seq_List (S310).

In step S310, it is determined whether a specification on the constraint condition is found in the out of order vehicle list Out_of_Seq_List that is equal to the out of order vehicle (S320).

In step S320, if found, a temporary variable (Found_Vehicle = vehicle 2) is assigned to the vehicle, and the flow proceeds to step S400 of exhausting the ordered vehicle.

In step S320, if it is not found, it is recorded as no temporary variable Found_Vehicle and the process proceeds to exhaustion of the deflection vehicle S400.

And the exhaustion of the order sag vehicle (S400) is the number of vehicles in the order sag vehicle list (Out_of_Seq_List) after the order maintenance step (S100) or vehicle specification replacement attempt step (S200) or replacement vehicle input attempt step (S300). It is determined whether is greater than 0. (S410)

In step S410, if the condition is not satisfied, the process proceeds to the final withdrawal scheduled vehicle registration step S500. If the condition is satisfied, the order sag vehicle is used by using the vehicle in the order sag vehicle Out_of_Seq_List. It is determined whether a batch set (Delay_Vehicle_Set) can be created (S420).

Here, in the batch processing vehicle batch processing delay (Delay_Vehicle_Set), when the ordering vehicle amount increases in the PBS, the ordering vehicle amount becomes relatively small in the PBS. In such a case, it is difficult to replace the sag vehicle in a short time by the replacement or replacement alone, and moreover, if there are many constraints, deadlocks can no longer be selected. Therefore, when the amount of the sagging vehicle is more than a certain degree, it is a set of conditions for preventing deadlock by separately managing the conditions that can eliminate the excessive phenomenon of the sagging vehicle at a time.

If the condition of step S420 is satisfied, a batch batch processing vehicle Delay_Vehicle_Set is created and all the vehicles therein are registered in the list of scheduled to-go vehicle list TDL_List (S430).

In step S420, if it is not possible to create the delayed vehicle batch processing set (Delay_Vehicle_Set), the parameter (i) values of all the vehicles in the ordered vehicle list (Out_of_Seq_List) are set in the PBS inflow order number order. Give (S440)

After the step S440, it is determined whether the i th vehicle, which is the parameter in the ordered vehicle list Out_of_Seq_List, violates any one of the constraints (S450).

In step S450, if it does not violate the constraint, the i-th vehicle 3 is registered in the ordered vehicle insertion list Insert_List (S460).

After the step S460, after the process of adding 1 to the parameter i = i + 1, the value of i added to 1 is the number of vehicles in the ordered vehicle list Out_of_Seq_List. It is determined whether or not it is larger (S470).

In step S470, if the condition is not satisfied, the process returns to step S450. If the condition is satisfied, all the vehicles in the ordered vehicle insertion list Insert_List are added to the list of the withdrawal scheduled vehicle list TDL_List. After registering, the process proceeds to the final withdrawal scheduled vehicle registration step (S500). (S480)

The final withdrawal scheduled vehicle registration step S500 is performed when the vehicle does not exist in the ordered vehicle list Out_of_Seq_List or the vehicle in the ordered vehicle list Out_of_Seq_List. Through this step S400 exhausted step (S400), it is determined whether there is no temporary variable (Found_Vehicle) for all the vehicles registered in the list of the withdrawal scheduled vehicle list (TDL_List) (S510).

In step S510, when there is no temporary variable Found_Vehicle, the process ends. When the temporary variable Found_Vehicle is assigned, the process ends by registering the temporary variable Found_Vehicle in the withdrawal scheduled vehicle list TDL_List.

As described above, according to the vehicle withdrawal method of the automatic painting vehicle body warehouse according to the present invention, in the PBS, a vehicle capable of maximizing sequence maintenance can be selected from the sequence maintenance vehicle list, and then interposed therebetween. By finding and injecting the vehicles that satisfy the constraints in the out-of-sequence vehicle list (Out_of_Seq_List) as much as possible, the exhaustion of the out-of-order vehicles can be exhausted as soon as possible, and at the same time as the level of work according to the operation conditions and production constraints of the design factory. In order to maintain the order, it is effective to increase the efficiency of line design management.

In addition, it is possible to solve the problems caused by the inability to synchronize the production of cooperative companies, which occurred in the conventional PUSH method, the logistics, investment, labor costs, etc. due to the operation of the internal parts warehouse can be eliminated, and due to the incorrect sequence order It also has the effect of minimizing the investment in additional IT sector for system supplement and production management operation.
