Preferably, in the above technical solution, the basic data in S1 mainly refers to relatively static data that can be maintained in advance, such as factories, workshops, production lines, planned productivity, rule calculation conditions, etc., and the order data mainly refers to data including order information, order feature information, and project orders.
Preferably, in the above technical solution, the vehicle configuration data analysis vehicle configuration data information is embodied in feature information of each vehicle, and the configuration information of each vehicle is also transmitted to a related service management system, a manufacturing execution system and a scheduling system when the production plan is broadcast; analyzing configuration data of each vehicle from order feature information, comparing the configuration data with the schedule basic data to obtain schedule basic data attributes of corresponding vehicles (orders), and calculating by referring to schedule limiting conditions to obtain a vehicle online sequence; feature data, particularly Feature family affecting the sequence plan calculation constraints, is required to be combed by the business department as basic data and predefined in the system.
Preferably, in the above technical solution, S3 is specifically: scheduling parameters of the scheduling system are selected and defined, the scheduling system models and calculates, a production sequence is generated, and the generated production sequence is audited and then is issued to the execution system.
Preferably, in the above technical solution, the arrangement parameters of the scheduling system are specifically selected and defined as follows: the method comprises the steps of manually inputting a sequencing rule of a vehicle body workshop, a sequencing rule of a painting workshop and a sequencing rule of a final assembly workshop, integrating the three rules to form a complete sequencing rule, and calculating whether sequencing conflict exists or not and prompting staff to exclude by combining the sequencing rule during system modeling operation.
Preferably, in the above technical solution, the following four calculation formulas are predefined in combination with the calculation formula of the system rule: up to N consecutive P positions occur; a maximum continuous number; leveling; a cannot follow N B; on the basis of the definition of the above limiting rules, coefficients, weights and priorities can be respectively set for each rule, and according to the definition of the latitudes, the settings are considered in calculation, and sequential planning result suggestions are comprehensively given; the coefficient, the weight and the priority are quantized indexes, and respectively represent the weight number occupied by the rule or the cost violating the rule in the evaluation of the result in the calculation process; wherein: coefficients: representing the weight occupied by the rule in the calculation process, wherein the calculation process considers the weighting factors; weight: representing the weight of the rule in the result evaluation; priority level: the priority is also the embodiment of the rule weight, and the calculation result is affected in different calculation stages in the calculation process like the coefficient.
Preferably, in the above technical solution, the method further includes an adjustment procedure, in which vehicles in the project management platform are out of order, the warehouse system determines whether to adjust the departure sequence according to the actual position condition of the on-site vehicles and the buffer vehicle body condition before coating and incoming line, taking into consideration the actual storage condition of the on-site vehicles, the project management platform calculates and issues the main sequence as a reference, and the vehicles are put according to the on-site actual conditions; for the car bodies which are not put in the original production main sequence, the passing point information is recorded and transmitted to an APS system for the consideration of the execution rate of the sequence plan and the early warning of the sequence abnormality.
Preferably, in the above technical solution, the sequence abnormal vehicle body departure sequence calculating logic is as follows:
Step 1, judging whether the vehicle body can go out according to the original main sequence according to the sequence abnormal vehicle body position condition (the vehicle body is late in the WBS, but the previous sequence vehicle body WBS is not finished), namely, according to the vehicle body position calculation, the vehicle body entering and returning channels of the corresponding lane are required to be adjusted according to the original sequence, so that the sequence abnormal vehicle body can take out preferentially, and meanwhile, the buffer time is calculated and adjusted according to the vehicle condition entering the buffer area before coating and the coating JPH. If the adjustment time is less than the buffering time, the indication is adjustable;
step 2, when the calculated result in the step 1 is that the adjustment time exceeds the buffer time, the APS system gives a result that the vehicle cannot be discharged according to the original sequence, and at the moment, the vehicle sequence capable of being discharged is recalculated according to the fastest vehicle discharging principle or the color priority principle predefined by the user;
Step 3, calculating the BDC platform real-time departure sequence, removing vehicles in the hold state by considering the BDC platform vehicle state and position acquired from the RC system, sorting according to the original main sequence after considering the locking logic, calculating whether the vehicles violate the general strong constraint vehicle-releasing rule one by one, if not, keeping the vehicle sequence unchanged, and continuously calculating the subsequent vehicles; if yes, the vehicle is skipped, a subsequent vehicle is calculated, and after the first subsequent vehicle is not scheduled in violation of the vehicle, the vehicle skipped by the calculation range rule is returned. The above calculation was repeated.
Preferably, in the above technical solution, whether the vehicle body in step 1 can be taken out in advance depends on adjusting the adjustment time required for entering the vehicle body in the return path. The adjustment time is related to the real-time vehicle body position of the WBS platform, and meanwhile, the vehicle body can not be parallel to the vehicle body in-out and in-in and out-out adjustment channels, and the vehicle body can be adjusted one by one in sequence. Therefore, the adjustment of the body sequence needs to be calculated in real time according to the vehicle condition of the WBS platform. When the vehicle is regulated, the following principle needs to be followed:
the number of the locking vehicle bodies is required to be set, and the sequence of the vehicle bodies in the locking number cannot be adjusted;
After the WBS eleven lanes are discharged, the buffer area (7 positions) before entering a painting workshop should be kept full of the vehicle body as much as possible;
Is adjusted into the body of the return channel, and returns to the original channel;
The vehicle is in a certain pass (in-and-out pass) when it is adjusted, and the pass is not allowed to reenter the vehicle body. After all adjustment, the vehicle can be put into the pass again;
When the out-of-order vehicle body meets the requirement of listing vehicles according to the original sequence, namely, the vehicle-out sequence of the WBS platform is unchanged, and the vehicle body is required to be adjusted according to the vehicle-out sequence on site.
Preferably, in the above technical solution, in step 2: the calculation logic is as follows: logic 1 when the principle is the fastest vehicle outlet, logic is that the vehicle outlet sequence and the previous vehicle sequence of the lane time are +1, namely the vehicle immediately exits the vehicle after the previous vehicle of the lane time exits;
When the principle is color priority, the logic 2 searches vehicles between the sequence numbers of the front and rear vehicle bodies of the vehicle pass, acquires color information of feature information of the part of vehicles, compares the color information with the color of the feature information of the trolley body, and takes the vehicle body with the same color, with the smallest sequence number, as the vehicle outlet sequence number of the trolley body, and sequentially pushes the vehicle outlet sequence of the rear vehicle body; if no body of the same color is found in the part of the vehicle, information is output: the proper vehicle body cannot be found, and at the moment, the system calculates the optimal sequence train number according to the rule to carry out train departure;
Logic 3 if the original sequence number of the out-of-order car body is the smallest sequence number in the WBS platform at the moment, namely the car body misses the sequence planning car-out sequence of the car body due to set out and the like, at the moment, according to the description logic in the step 1, calculating whether the car body priority car-out time is smaller than the buffer time, if so, the car-out sequence is unchanged, the car is the smallest sequence number in the platform at the moment, the car should be first taken out, and the car is controlled to be preferentially taken out in the RC platform; if the number is larger than the preset number, the trolley cannot be taken out preferentially, and the step 2 is entered, and the vehicle-out sequence of the trolley body is calculated.
Preferably, in the above technical solution, when the vehicle body enters the project work decomposition platform but needs to go first, the logic 1, the logic 2 and the logic 3 are calculated according to the above departure sequence, and the project work decomposition platform departure sequence is calculated.
When the WBS platform vehicle body sequentially replaces or adjusts the vehicle VIN, firstly, the production planning time of the vehicle needs to be definitely replaced, if the vehicle spans the day, the production planner and the material planner need to communicate the material risk outside the system, and after confirming that the material is free of the risk, the calculation replacement logic is executed; if the days are not crossed, executing the calculation replacement logic; the replacement logic is that the vehicle body to be replaced and the vehicle body to be replaced need to be represented that the vehicle body can be replaced when the family code value (specific configuration item) of the designated feature completely accords. When calculating, considering all on-line vehicle bodies of the welding schedule on the same day, calculating the vehicle bodies which can be replaced according to the principle that the vehicle body forms are consistent (specific configuration items), outputting the vehicle bodies in a report form, judging which vehicle body is replaced by a production planner, and manually completing the adjustment of the sequence plan. For replacement business, related information such as car body bar codes and the like needs to be synchronously replaced on site.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising" or the like will be understood to include the stated element or component without excluding other elements or components.
The APS scheduling system is used for discharging a corresponding sequence plan according to a specific rule for an on-the-day production plan, guiding the on-line sequence of the vehicle, and refreshing sequence information when the production site is abnormal so as to achieve the aim of quick response.
The APS scheduling management business process description business end starts from the front end access production plan and related data, calculates to the sequence plan, adjusts and distributes to the sequence plan, collects the passing point information and platform information in the execution process, and the WBS platform skips into the vehicle body mixed arrangement, and then performs the whole process of sequencing and distribution of sequencing according to the abnormality of the execution process.
Sequential planning rules are used to describe production line scheduling constraints, such as economic lots, process limitations, etc., which are typically embodied by a particular model, configuration.
At present, the related information such as CToB modes, vehicle types, configuration and the like of the large automobile can be embodied in features (configuration packages), and in the future, based on the VDC data of the large automobile, each detail family code+feature Code in the features is adopted as basic data of limiting conditions, and the definition of the scheduling limiting conditions is based on the basic data. The data are exemplified as follows:
Based on the principle, the communication with relevant business personnel is clear, and the business end has combed a version of limiting conditions as follows:
。

Weight of (1): representing the weight of the rule in the result evaluation
Priority of (2): the priority is also the expression of the rule weight, and the calculation result is affected in different calculation stages in the calculation process like the coefficient
Vehicle configuration data parsing: the configuration data information of the large-traffic vehicles on the bus is reflected in feature information of each vehicle, and the configuration information of each vehicle is transmitted to relevant SAP, MES and APS scheduling systems when the production plan is broadcast.
Analyzing the configuration data of each vehicle from the order feature information, comparing the configuration data with the schedule basic data to obtain the schedule basic data attribute of the corresponding vehicle (order), and calculating by referring to the schedule limiting condition to obtain the vehicle on-line sequence.
Feature data, particularly Feature family affecting the sequence plan calculation constraints, is required to be combed by the business department as basic data and predefined in the system.
Sequential planning calculations are generally divided into four steps:
Is input with data:
u base data (static): factories, production lines, workshops, teams, work calendars, etc.;

The data input part is divided into static data and dynamic data, and the static data mainly refers to data which can be maintained in advance, such as factories, workshops, production lines, planning productivity, rule calculation conditions and the like, and the dynamic data, namely actual business data, are obtained from an MES system in the process of executing business and comprise production plans (including project orders) and order feature information. Wherein the item orders are distinguished on the order type. I.e., project orders are also passed by the MES to the APS through the interface for sequential planning calculation unification consideration.
Based on the above data, a sequential plan is calculated according to predefined ordering rules, and simulation results are given and evaluated.
Description of the preferred embodiments
For the disorder of vehicles in the WBS platform caused by the abnormal situation of the workshop site, the RC system judges whether to adjust the vehicle outlet sequence according to the actual position situation of the site vehicles and the buffer vehicle body situation before coating the incoming line, and considers the actual storage situation of the site pass vehicles, the WBS platform calculates and issues the actual vehicle outlet sequence by using the APS as a reference, and the vehicles are put according to the actual site situation. For the car bodies which are not put in the original production main sequence, the passing point information is recorded and transmitted to an APS system for the consideration of the execution rate of the sequence plan and the early warning of the sequence abnormality.
The WBS platform regularly refreshes platform vehicle information, and calculates whether the current vehicle position can be sequentially taken out according to a sequential plan after refreshing the WBS platform vehicle each time. If yes, refreshing a vehicle departure sequence; if the problem exists, alarming, displaying WBS platform sequence abnormality reminding on a homepage, checking abnormal vehicle conditions by a central controller, and judging and adjusting.
When the vehicle departure sequence is refreshed, the situation that the sequence numbers such as hold vehicles, set out and the like jump numbers occurs, and if the vehicles can be departure from the small to the large sequence numbers (the sequence numbers are from front to back) in sequence, no abnormality is indicated, and the departure sequence (the sequence arrangement from the current departure sequence to the minimum number) is updated (the sequence needs to be adjusted).
When the vehicle cannot be driven out according to the sequence and a warning is reported, a central control operator informs a production planner, and the production planner judges whether to change the WBS platform vehicle-out sequence according to the vehicle sequence number and the WBS platform vehicle condition. The calculation logic of the sequence abnormal car body departure sequence is as follows:
1. According to the situation of the sequential abnormal vehicle body position, judging whether the vehicle body can go out in sequence according to the original main sequence (for the vehicle body late-entering WBS, but the situation that the vehicle body in front sequence is not yet out of WBS), namely, according to the vehicle body position calculation, the vehicle body entering and returning channels of the corresponding lane need to be adjusted, so that the sequential abnormal vehicle body takes precedence for the time of the vehicle body to go out, and meanwhile, according to the vehicle situation of entering a buffer zone (7 vehicle bodies) before coating and the situation of coating JPH, the adjustment buffer time is calculated. If the adjustment time is less than the buffering time, it indicates that adjustment is possible.
Whether the car body can be taken out in advance depends on the adjustment time for adjusting the car body needing to enter and return the road. The adjustment time is related to the real-time vehicle body position of the WBS platform, and meanwhile, the vehicle body can not be parallel to the vehicle body in-out and in-in and out-out adjustment channels, and the vehicle body can be adjusted one by one in sequence. Therefore, the adjustment of the body sequence needs to be calculated in real time according to the vehicle condition of the WBS platform. When the vehicle is regulated, the following principle needs to be followed:
is required to set the number of locking bodies, and the sequence of the bodies in the number of locking cannot be adjusted
After the WBS eleven lanes are discharged, the buffer area (7 positions) before entering the painting workshop should be kept full of the vehicle body as much as possible
Is adjusted into the body of the return channel to return to the original channel
When the vehicle is adjusted (entering and returning to the road), the vehicle is not allowed to enter the vehicle body again in a specific pass. Can be put into the pass again after all adjustment
When the out-of-order vehicle body meets the requirement of listing vehicles according to the original sequence, namely, the vehicle-out sequence of the WBS platform is unchanged, and the vehicle body is required to be adjusted by vehicle-out according to the sequence on site.
2. When the calculated result in 1 is that the adjustment time exceeds the buffer time, the APS system gives a result that the vehicle cannot be taken out according to the original sequence, and the vehicle-taking-out sequence is recalculated according to the fastest vehicle-taking-out principle or the color priority principle predefined by the user.
When the principle is the fastest vehicle outlet, the logic is that the vehicle outlet sequence and the previous vehicle sequence of the lane number are +1, namely the vehicle is immediately discharged after the previous vehicle is discharged in the lane number
When the principle is color priority, the vehicles between the sequence numbers of the front and rear vehicle bodies of the vehicle pass are searched, the color information of the feature information of the part of vehicles is obtained, the vehicle bodies with the same color as the color of the feature information of the trolley body are compared, the vehicle body with the smallest sequence number is taken as the vehicle outlet sequence number of the trolley body, and the vehicle outlet sequence of the rear vehicle body is sequentially pushed. If no body of the same color is found in the part of the vehicle, information is output: a proper vehicle body cannot be found and the sequence is manually adjusted. At this time, the departure sequence is manually adjusted by the production planner.
If the original sequence number of the out-of-order car body is the smallest sequence number in the WBS platform at the moment, namely, the car body misses the sequence planning car-out sequence of the car body due to set out and the like, at the moment, whether the car body priority car-out time is smaller than the buffer time or not is calculated according to the logic described in the step 1, if so, the car-out sequence is unchanged, the car is the smallest sequence number in the platform at the moment, the car should be first taken out, and the car is controlled to be preferentially taken out in the RC platform. If the number is larger than the preset number, the trolley cannot be taken out preferentially, and the step 2 is entered, and the vehicle-out sequence of the trolley body is calculated.
Is a business case:
Is a vehicle body backward WBS platform but requires a first out
Vehicle body sequence replacement (vehicle VIN number adjustment, etc.) of WBS platform
Aiming at the service situation 1, calculating the WBS platform departure sequence according to the departure sequence calculation logic 1,2 and 3; aiming at the business situation 2, firstly, the production planning time of the vehicle needs to be definitely replaced, if the vehicle spans the day, the production planner and the material planner are required to communicate the material risk outside the system, and after confirming that the material is free of the risk, the calculation replacement logic is executed; if not, then compute replacement logic is performed. The replacement logic is that the vehicle body to be replaced and the vehicle body to be replaced need to be represented that the vehicle body can be replaced when the family code value (specific configuration item) of the designated feature completely accords. When calculating, considering all on-line vehicle bodies of the welding schedule on the same day, calculating the vehicle bodies which can be replaced according to the principle that the vehicle body forms are consistent (specific configuration items), outputting the vehicle bodies in a report form, judging which vehicle body is replaced by a production planner, and manually completing the adjustment of the sequence plan. For replacement business, related information such as car body bar codes and the like needs to be synchronously replaced on site.
Calculating the BDC platform real-time vehicle-out sequence, removing vehicles in the hold state by considering the vehicle state and the position of the BDC platform acquired from the RC system, sorting according to the original main sequence after considering the locking logic, calculating whether the vehicles violate the general assembly strong constraint vehicle-out rule or not one by one, if not, keeping the vehicle sequence unchanged, and continuously calculating the subsequent vehicles; if yes, the vehicle is skipped, a subsequent vehicle is calculated, and after the first subsequent vehicle is not scheduled in violation of the vehicle, the vehicle skipped by the calculation range rule is returned. The above calculation was repeated.
Examples are as follows:
。
In the above example, if the original sequence numbers 0020 and 0040 do not participate in calculation, then after 0010, the calculation 0030 does not violate the strong constraint rule, and the sequence is 0030; continuing to calculate 0050 vehicles, violating the rules, skipping, calculating 0060, 0060 without violating the rules, and returning to calculating 0050 with unchanged order, still 0060. At this point 0050 has not violated the rules, but the vehicle cannot be driven with the original sequence number, and if +1 is needed on the basis of the last scheduled vehicle sequence number (0060), the new driving sequence number of the original 0050 vehicle becomes 0061, and the calculation of the following vehicles is continued.
When calculating, the locking vehicles are required to be set, and the locking quantity rolls. For example, the number of locks is 5, the first calculation is to lock the first 5, and when the second calculation is performed, the locked 5 trolleys are out of 2 trolleys, and on the basis of 3 locking, the subsequent departure sequence is continuously calculated, so that 5 trolleys are locked as a result.
Special cases and rules:
If the obtained data does not obtain the vehicles marked with the locking marks, the number of the vehicles is indicated to exceed the number of the locked vehicles, and the vehicle sequence is recalculated from the one with the smallest original sequence number in BDC;
If all the following vehicles violate the total loading rules from a certain platform, the calculation is jumped out, and the loading sequence of the vehicles which do not violate the rules is given.
Through intelligent scheduling algorithm and execution, the method is manufactured automatically by digital drive, and the C2B customized production service mode is supported more effectively, so that the scheduling standardization, result refinement and process visualization are realized.
