The enterprise management software is integrated aiming at material resource management (logistics), human resource management (people flow), financial resource management (financial flow) and information resource management (information flow).
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1, the embodiment provides an auxiliary balancing method for a scheduling delivery period of an order of a multi-production line, which includes the following steps:
s1: maintaining production time for each model for the model to be produced.
Specifically, the standard time of each machine type in a production line and the standard time of different process stages are maintained and used for judging the time of each machine from ordering to warehouse preparation to feeding to product assembly to complete off-line operation, wherein the main board assembly also comprises warehouse preparation and transportation time; the machine assembly time further includes a motherboard assembly completion delivery time. The time required by production can be accurately calculated through maintenance of each model of each production line.
S2: and setting the scheduling time for the production line to determine the corresponding working time.
S3: and acquiring all order states under the current ERP system, and screening unlocked orders according to the order states to serve as orders needing scheduling and delivery period auxiliary balance.
The order states under the current ERP system are divided into four types, namely, order issuing, placing, production and order ending. Wherein, the order which is just synchronized from the ERP system is issued, and the scheduling is not carried out; putting into production is a scheduled order but not a production order; the order is currently being produced; the order is the order that has been produced. The open state order and the put-in-production state order are locking orders at the forefront of each production line and cannot be optimized; and the order of the issued state and the order of the production state are unlocked orders, and for the unlocked orders, after the order of the reached state is converted into the production state, auxiliary balance of the production scheduling delivery period is carried out.
S4: order information of orders needing scheduling delivery period auxiliary balance is synchronized in the MES system, the required time of each machine in each production line is calculated according to the order information, and order delivery time is used as a final constraint condition.
Because the production planning and scheduling come from the ERP system, after the MES system synchronizes the order information, the order number, the order quantity, the order model, the order delivery time and other information are obtained. The required time of each machine on each production line is intelligently calculated according to the order number and the model information and the production capacity of the production line to be maintained, and the delivery time is used as a final constraint condition.
S5: and starting an auxiliary production scheduling mechanism, and performing production line production scheduling matching on the orders needing auxiliary balance in the production line delivery period according to the required time length and the order delivery time of each production line.
S6: and judging whether the scheduling matching is successful or not, if so, directly ending, and if not, turning to the next step.
S7: and (4) performing auxiliary construction period assisted production scheduling by using the page Gantt chart, judging an overdue order according to a production scheduling result, and identifying.
If the matching fails, the page Gantt chart is needed to be manually used for scheduling, the MES system can automatically judge the delivery date conditions of all orders, and the orders which do not meet the delivery date can be automatically displayed as a red flow.
S8: and (5) carrying out a sheet cutting operation for the overdue order through the MES system, and returning to the step S5 for scheduling matching.
If the decision maker receives the result of the previous step and still cannot balance, the order cutting operation can be carried out through the MES system, the large order is cut, then the step 5 is skipped to carry out matching, and the output result can meet the requirement all the time.
As an example, as shown in fig. 2, the auxiliary scheduling mechanism includes the following steps:
s501: retrieving a production line code L [1,2, …, n ], a time T [1,2, …, n ] required for processing the order which has been scheduled by the current production line and a time Te required for delivering the order O1 from a database of the MES system;
s502: calculating required production time Tp [ i ] according to the order number and the maintained production time of a single machine;
s503: assigning an initial value i to 0;
s504: i + +, traversing the production line L [ i ];
s505: judging whether i is less than or equal to n, if so, turning to the next step, otherwise, turning to the step S509;
s506: judging whether T [ i ] + Tp [ i ] < ═ Te of the current production line is true, if yes, turning to the next step, and if not, turning to the step S504;
s507: arranging the order on a production line L [ i ] for production;
s508: returning to match success, and suggesting that order O1 is produced on the production line L [ i ];
s509: searching the order time Tl [ i ] of the last production line of each production line;
s510: assigning an initial value i to 0;
s511: i + +, traversing the production line L [ i ];
s512: judging whether i is less than or equal to n, if so, turning to the next step, otherwise, turning to the step S523;
s513: judging whether T [ i ] + Tp [ i ] -Tl [ i ] < ═ Te of the current production line is true, if yes, going to the next step, and if not, going to the step S511;
s514: arranging the order on a production line L [ i ] for production;
s515: assigning the required delivery time after the scheduling of the current production line L [ i ] to Te, and assigning the order number O [ i ] to O2;
s516: calculating required production time Tp according to the order data and the maintained production time of a single machine;
s517: assigning an initial value j equal to 0;
s518: j + +, traverse the production line L [ j ];
s519: judging whether j is less than or equal to n, if so, turning to the next step, otherwise, turning to the step S523;
s520: judging whether T [ j ] + Tp [ i ] < ═ Te of the current production line is true, if yes, going to the next step, and if not, going to the step S518;
s521: producing order O2 on production line Lj;
s522: returning to match success, suggesting that order O1 is produced on the production line L [ i ], and order O2 is produced on the production line L [ j ];

s701: retrieving all the order codes O [1,2, …, n ], the current order end time T [1,2, …, n ] and the delivery period Te [1,2, …, n ] of each order from the database of the MES system;
s702: judging whether the order is overdue or not;
s703: assigning an initial value i to 0;
s704: i + +, traverse order O [ i ];
s705: if T [ i ] + Tp [ i ] < ═ Te is true, go to step S706 if yes, otherwise go to step S707;
s706: recording the current order number O [ i ] and the expiration time T ═ Te [ i ] -T [ i ];
s707: judging whether i is less than or equal to n, if so, turning to the step S704, otherwise, turning to the next step;
s708: the recorded order number O [ i ] is returned and marked as the overdue order number.
