Description

Technical Field

[0001] The present invention relates to the field of automation control technology, and in particular to a planning and collaborative advanced production scheduling system for a cold drink factory. Background Art

[0002] Food enterprises are typical process manufacturing businesses. The characteristics of food production mainly include high-quality raw material selection and sophisticated process flow. Traditional production planning management relies on manual preparation of finished product production plans and semi-finished product production plans, and then the production process mainly relies on planning and scheduling personnel for scheduling and command. This production planning model has shown the shortcomings of manual management in the continuous development of food production. With the expansion of market demand, scheduling and organizing production through human brains has made the production connection between each workshop not rigorous, lacking unified command, and production information opaque.

[0003] Cold drink factories are also special among food factories. Semi-finished products of cold drinks such as egg rolls, chocolate, and milk ingredients involved in ice cream have specific storage requirements and storage time limits. They need to be produced as finished products as soon as possible after the semi-finished products are produced to ensure the taste and food safety of the finished products. The existing collaborative production scheduling is mostly applied to processed products such as mechanical parts and plastic products that can be stored for a long time, and the production scheduling effect is not good for cold drink factories with many restrictions. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a planning and collaborative advanced scheduling system for cold drink factories, which solves the technical problem that existing cold drink factories cannot achieve effective planning and collaborative scheduling due to restrictions on production volume, semi-finished product storage time limit, semi-finished product production time limit, etc.

[0005] A planning and collaborative advanced production scheduling system for cold drink factories, comprising an information acquisition module, an order sorting module, a process disassembly module, a production line sorting module, and an integrated production scheduling module; the information acquisition module is used to obtain demand order information and production information of the current production line, the demand order information includes a delivery date and an order priority, the order sorting module is used to sort orders according to the demand order information, the process disassembly module is used to process-disassemble the top-ranked orders output by the order sorting module, and clarify the production steps; the production line sorting module is used to sort the production lines according to the current production situation; the integrated production scheduling module is used to design a production schedule based on the output results of the process disassembly module and the production line sorting module and issue it to the corresponding production line.

[0006] Furthermore, the production line includes multiple semi-finished product production lines and finished product production lines. The production line sorting module classifies each production line and sets corresponding priorities, including the production line that is currently executing the production plan, namely the Class A production line, the idle production line but with a production plan, namely the Class B production line, and the idle production line without a production plan, namely the Class C production line. The time when the Class A production line ends production is T A , the estimated idle time of Class B production line is T B ;

[0007] The A-type production line is T A Sort by T A The shorter the length, the higher the ranking.

[0008] The B production line is T B Sort by T B The longer it is, the higher it is sorted;

[0009] The specific production line priority ranking is Class C production line > Class B production line > Class A production line.

[0010] The specific output results are as follows:

[0011] {{C1, T α1 , P α1}, {C2, T α2 , P α2}, {C1, T α3 , P α3}...{C1, T αn , P αn}}

[0012] {{C2, T α1 , P α1}, {C2, T α2 , P α2}, {C1, T α3 , P α3}...{C1, T αn , P αn}} ...

[0014] {{C n , T α1 , P α1}, {C2, T α2 , P α2}, {C1, T α3 , P α3}...{C1, T αn , P αn}}

[0015] In the formula, C n is the nth semi-finished product production line, α=A,B,C,Tαn is the time of the nth production line in the αth type of production line, P αn is the priority of the nth production line of the αth type production line.

[0016] Furthermore, the output results of the process disassembly module include various semi-finished product types, corresponding production line types, production time required according to the demand order quantity, production priority, finished product types, production line types corresponding to finished product types, production time required according to the demand order quantity, and production priority. Specifically, the production order is determined according to the type of semi-finished products. For example, semi-finished products that can be temporarily stored after production will be produced first, and semi-finished products that need to be used in time after production will be produced after other semi-finished products are completed. If there are semi-finished products that need to be used in time, the finished products must be produced in time after all semi-finished products are completed.

[0017] The specific output results are as follows:

[0018] {{L 11 ,C 11 ,T 11 ,P 11},{L 12 ,C 12 ,T 12 , P 12},..{L 1n ,C 1n ,T 1n ,P 1n},{L1,C A ,T1,P1}}

[0019] {{L 21 ,C 21 ,T 21 ,P 21},{L 22 ,C 22 ,T 22 , P 22},..{L 2n ,C 2n ,T 2n ,P 2n},{L2,C A ,T2,P2}} ...

[0021] {{L N1 ,C N1 ,T N1 ,P N1},{L N2 ,C N2 ,T N2 , P N2},..{L Nn ,C Nn ,TNn ,P Nn},{L N ,C N ,T N ,P N}}

[0022] Where, L Nn The type of the nth semi-finished product required for the Nth type of finished product, C Nn is the production line corresponding to the nth type of semi-finished product required by the Nth type of finished product, T Nn is the production time of the nth semi-finished product required for the Nth type of finished product, P Nn The production priority of the nth semi-product of the Nth type of finished product.

[0023] Furthermore, the integrated production scheduling module is used to arrange and combine the production lines and various semi-finished products and finished product production requirements according to the output results of the production line sorting module and the process disassembly module, and use the greedy algorithm to find the optimal monthly production plan, and then generate a daily production plan based on the monthly production plan, and send the daily production plan to each production line workshop to guide production.

[0024] Furthermore, the objectives of the greedy algorithm include:

[0025] The largest number of orders completed each month:

[0026]

[0027] Where Y i is the demand order quantity completed on the i-th day, and n is the number of days in the month;

[0028] The semi-finished product has the shortest waiting time for the finished product:

[0029]

[0030] t k is the time to start producing finished products for the kth demand order, t kj is the production completion time of the jth semi-finished product in the kth demand order, and N is the maximum number of orders produced in the month;

[0031] The difference between order completion time and delivery time is the shortest:

[0032]

[0033] T y is the estimated delivery time for the yth demand order, t y is the production completion time of the yth demand order, and N is the maximum number of orders produced in the month;

[0034] Integration goal: Highest production line efficiency

[0035]

[0036] Where, T month The total working hours for the month.

[0037] Furthermore, the constraints of the greedy algorithm include:

[0038] Order completion time is less than or equal to delivery time:

[0039] t y ≤T y

[0040] T y is the estimated delivery time for the yth demand order, t y is the production completion time of the yth demand order, and N is the maximum number of orders produced in the month;

[0041] The storage time of a specific semi-finished product is less than or equal to the maximum storage time:

[0042] t k -t kj ≤T zan

[0043] In the formula, t k is the time to start producing finished products for the kth demand order, t kj is the production completion time of the jth semi-finished product in the kth demand order, T kjm The maximum time that the jth semi-finished product in the kth demand order can be temporarily stored.

[0044] Furthermore, it also includes an MRP module for summarizing and displaying the current production information and planned production information of the production line, order completion status and raw material inventory status in real time.

[0045] Furthermore, the MRP module can regularly calculate the raw material demand for a period of time in the future according to the production plan and compare it with the raw material inventory. If the raw material inventory is insufficient to meet the raw material demand of the daily production plan, a prompt message for purchasing raw materials will be issued.

[0046] Furthermore, the MRP module regularly verifies whether the raw material inventory consumption matches the completed production plan. If it does not match, it issues a prompt message indicating that the raw material consumption is incorrect.

[0047] The beneficial effects of the present invention include:

[0048] According to the production characteristics of the cold drink factory, various production lines are classified and counted. At the same time, the production needs of various semi-finished products and finished products are generated according to the demand orders. Then, the best permutation and combination are obtained through the designed greedy algorithm. On the premise of meeting the order demand and production demand, the production line is fully utilized to shorten the waiting time of semi-finished products as much as possible, increase production output, and maximize the operation efficiency of the production line, thereby avoiding idle production lines due to the time difference in the production process between semi-finished products and semi-finished products, and realizing efficient collaborative production scheduling.

Specifically, the production sequence is determined according to the semi-finished product type. For example, the semi-finished products that can be temporarily stored after production are produced first, and the semi-finished products that need to be used in time after production are produced after other semi-finished products are completed. If there are semi-finished products that need to be used in time, the finished products must be produced in time after all the semi-finished products are completed;
