In order to improve sorting efficiency and facilitate the description of the following embodiments, referring to fig. 2, in this embodiment, a process of delivering cigarettes from a pallet vertical warehouse to a sorting line is divided into a replenishment section and a supply section in business, and the replenishment section strategy and the supply section strategy are designed in strategy.
The cargo supplementing section strategy of this embodiment is as follows: analyzing the standard and classifying the strategy; firstly, preparing goods and establishing a cache; two replenishment logic double-line processes are executed to supplement each other, so that the replenishment timeliness is ensured; the strategy of the goods supply section is as follows: constructing a task delivery queue according to a sorting line scheduling plan; task polling and batch issuing.
The specification analysis and policy classification are specifically described below:
the standard analysis and policy classification are mainly to perform standard analysis on the cigarettes, and then select a corresponding storage policy according to the analyzed standard, namely, the content of step S101 in this embodiment, the classification of the standard and the selection of the corresponding storage policy are shown in table 1.
TABLE 1
The class A, the class B and the class C are divided according to commercial tobacco market demand, and compared with the multi-pass warehouse-out efficiency, the multi-speed chain has higher warehouse-out efficiency and quicker turnover, so that the design of multi-speed chain storage is adopted for class A cigarettes with larger market demand, and the conveying demand can be met by adopting multi-pass storage for class B cigarettes and class C cigarettes with relatively smaller market demand, so that the sorting efficiency is improved.
The following details of the establishment of a buffer memory are given in advance of stock:
in this embodiment, the stock advance establishes a stock strategy in which the buffer is mainly divided into a class a tobacco stock strategy and a class B tobacco stock strategy and a class C tobacco stock strategy, wherein step S102 is the class a tobacco stock strategy, and step S103 is the class B tobacco stock strategy and the class C tobacco stock strategy.
Specifically, the class a tobacco inventory strategy is: judging whether the next day sorting row Cheng Dingshan is received; if the data are received, the warehouse entry standard of the double-speed chain and the number of the double-speed chain mouth are analyzed according to the next day sorting scheduling order; if not, analyzing the warehouse entry standard of the speed-doubling chain and the number of the speed-doubling chain mouth according to the historical order data; and after the number of cigarettes required by the class A cigarettes is obtained, the number of cigarettes required by the class A cigarettes is obtained in a mode of full speed chain preparation, trays are distributed according to the number of cigarettes required by the class A cigarettes and in a mode of disc scattering priority, and the class A cigarettes are conveyed to the speed chain through the distributed trays.
In one embodiment, the WMS system determines whether the next day sort bar Cheng Dingshan is received; if the data are received, the warehouse entry standard of the double-speed chain and the number of the double-speed chain mouth are analyzed according to the next day sorting scheduling order; if not, analyzing the warehouse entry standard of the speed-doubling chain and the number of the speed-doubling chain mouth according to the historical order data; after the number of cigarettes required by the class A cigarettes is obtained, the WMS system obtains the number of cigarettes required by the class A cigarettes in a full speed chain preparation mode, then distributes trays according to the number of cigarettes required by the class A cigarettes and in a disc-scattering priority mode and generates corresponding tasks, then distributes the tasks to the WCS system in batches after the WMS system distributes the tasks, and the WCS system conveys the class A cigarettes to the speed chain according to the distributed tasks and through the distributed trays.
The task is generated by the WMS system, the scheduling execution of the task is completed by the WCS system, the task generated by the WMS system is issued to the WCS system in batches, then the WCS system receives the batch task and then flexibly schedules and executes the task in combination with the preparation condition of the field device, and the batch issuing is convenient for the WCS system to flexibly schedule.
In this embodiment, the speed-doubling chain is designed according to an integrated planning, the number of the speed-doubling chains (an upper layer and a lower layer, each layer has 8 road openings) is constrained from the hardware level, the maximum 8 product gauges (the sorting lines 1 and 3 in fig. 2 correspond to the upper layer of the speed-doubling chain and the sorting lines 2 and 4 correspond to the lower layer of the speed-doubling chain and are delivered, so that the same product gauge is arranged on the upper layer and the lower layer, and the speed-doubling chain is allowed to be provided with 8 product gauges at most), and if a next day sorting scheduling order is received, the warehouse-in product gauge of the speed-doubling chain (namely, the tobacco product gauge delivered to the speed-doubling chain) is analyzed according to the next day sorting scheduling order; and if the next day sorting scheduling order is not received, historical data are acquired, the requirement of the standard is analyzed, the most-popular standard can be obtained through sorting from large to small, and then the first 8 most-popular standards are defined as class A cigarettes, wherein the stock capacity of each crossing is 65.
Further, the number of cigarettes required by the class-A cigarettes is obtained in a full speed chain mode, namely 65 multiplied by 8 multiplied by 2=1040, namely 1040, and the risk of replenishment can be reduced in the class-A cigarettes.
And then distributing trays according to the required quantity of the 1040 cigarettes and in a scattered disc priority mode, namely conveying the cigarettes in the scattered disc to a double-speed chain in the scattered disc priority mode, for example, 65 cigarettes are fully required, the brand stacking standard is 30 cigarettes, 3 trays are respectively (30, 30 and 5) if the brand stacking standard is 30 cigarettes, wherein 30 is the whole disc quantity and 5 is the scattered disc quantity, and the WMS system preferentially checks whether the standard has 5 trays in inventory or not in inventory, and if so, preferentially distributes the 5 trays in inventory out of inventory.
Further, the stock strategies of the class B cigarettes and the class C cigarettes are as follows:
judging whether the next day sorting row Cheng Dingshan is received;
if the cigarettes are received, the safe stock quantity of the cigarettes in class B or class C is obtained according to the next day sorting scheduling order, then the trays are distributed according to the safe stock quantity of the cigarettes in class B or class C and in a scattered disc priority mode, and the cigarettes in class B or class C are conveyed to a plurality of penetrating warehouse through the distributed trays;
If not, acquiring the safety stock quantity of the class B cigarettes or the class C cigarettes according to the historical order data, distributing the trays according to the safety stock quantity of the class B cigarettes or the class C cigarettes and in a scattered disc priority mode, conveying the class B cigarettes or the class C cigarettes to the multi-penetrating warehouse through the distributed trays, comparing and analyzing the safety stock quantity with the sorting schedule after the sorting schedule is issued to obtain the difference quantity of the class B cigarettes or the class C cigarettes, and supplementing the class B cigarettes or the class C cigarettes to the multi-penetrating warehouse according to the difference quantity.
In one embodiment, the WMS system determines whether the next day sort bar Cheng Dingshan is received;
if the task is received, the WMS system acquires the safe stock quantity of the class B cigarettes or the class C cigarettes according to the next-day sorting scheduling order, then distributes trays according to the safe stock quantity of the class B cigarettes or the class C cigarettes and in a scattered disc priority mode to generate corresponding tasks, and then distributes the tasks to the WCS system in batches after the WMS system distributes the tasks to the WCS system, and the WCS system transmits the class B cigarettes or the class C cigarettes to a plurality of penetrating warehouse according to the tasks and through the distributed trays;
if the cigarettes are not received, the WMS system acquires the safe stock quantity of the cigarettes of class B or class C according to the historical order data, then distributes trays according to the safe stock quantity of the cigarettes of class B or class C and generates corresponding tasks according to a scattered disc priority mode, then distributes the tasks to the WCS system in batches after the distribution is completed, the WCS system conveys the cigarettes of class B or class C to the multi-penetrating warehouse according to the tasks and through the distributed trays, after the sorting scheduling is distributed, the WMS system compares and analyzes the safe stock quantity with the sorting scheduling to obtain the difference quantity of the cigarettes of class B or class C and generates corresponding tasks, and then the WMS system distributes the tasks to the WCS system in batches, and the WCS system supplements the cigarettes of class B or class C to the multi-penetrating warehouse according to the tasks.
The comparison analysis of the safety stock quantity and the sorting schedule mainly comprises a time difference, when the next-day sorting schedule order is not received, the stock is obtained according to the stock result obtained after the historical data analysis, after the next-day sorting schedule order is issued, whether the stock quantity meets the actual requirement can be known in a comparison mode, the difference quantity can be calculated in a comparison mode, the difference quantity is used as a subsequent stock supplementing quantity, the WMS system can distribute the stock, and then the generating task is issued to the WCS system. For example, the safety stock of the class B cigarettes is defined as 500 (stock quantity) according to the historical data analysis, after the next day production plan is issued, the actual demand quantity of the class B cigarettes is 550, the stock quantity of the pallet vertical warehouse is 50, and the WMS distributes stock to meet according to 50, so that a task is generated and issued to the WCS system, and the WCS system executes the task.
In this embodiment, the inventory allocation policy of the multi-pass library is shown in table 2:
TABLE 2
The total stock quantity of the multi-pass warehouse in the embodiment is 4400, the safety stock quantity of the class B cigarettes and the class C cigarettes is about 4000, and 400 stock positions are reserved for use in the scene of equipment abnormality or turnover for the needs of time.
It should be noted that, the constraint lower limit value of stock quantity of the multi-pass warehouse, namely the lowest stock quantity of the multi-pass warehouse, needs to be analyzed in advance.
Assume that: the efficiency of tobacco entering the multi-pass warehouse is Va, the efficiency of tobacco leaving the multi-pass warehouse is Vb (3600 pieces/hour are required to be met according to technical requirements), the total sorting order quantity is W (including double-speed chains and multi-pass storage), the multi-pass warehouse advance stock quantity is C, the double-speed chain advance stock quantity is B, the sorting time consumption according to the total order quantity is T, the number of redundant warehouse positions is X (adjustable according to actual conditions), and the multi-pass warehouse capacity is S.
When the manipulator is in full-load operation, va is the largest at this moment, when the sorting operation is finished, the multi-pass warehouse is just emptied, and the multi-pass warehouse under the condition is the lowest warehouse, and the following needs to be satisfied:
t=w/Vb-inclusive multiple speed chain
Cmin= (Vb-Va) T-double speed chain
From the above two formulas, cmin= [ (Vb-Va)/Vb ]. W, and when the sum of the multi-pass stock quantity plus the double-speed chain stock quantity is greater than Cmin, the sorting requirement can be guaranteed, so that the multi-pass stock quantity is required to satisfy:
[(Vb-Va)/Vb]*W-B＜C＜S-X
wherein, the safe stock quantity of the cigarettes of a certain standard of class B cigarettes and class C cigarettes can be obtained by the following formula:
safety stock of certain class B cigarettes and class C cigarettes= (number of cigarettes required by sorting order/total number of cigarettes required by sorting order) ×number of class B cigarettes and class C cigarettes allowed stock
The safety stock quantity of standard cigarettes and nonstandard cigarettes can be calculated on site according to actual conditions.
The following two replenishment logic double-line processes are executed to supplement each other, and the replenishment timeliness is guaranteed to be specifically explained:
the two replenishment logics are replenishment strategies of class A cigarettes and replenishment strategies of class B cigarettes and class C cigarettes respectively, and the replenishment timeliness is guaranteed by the two-thread operation of the replenishment strategies of class A cigarettes and the replenishment strategies of class B cigarettes and class C cigarettes.
Wherein, the replenishment strategy of the class A cigarettes comprises polling available stock digits (i.e. empty stock digits) of the double-speed chain according to a first preset time; then judging whether the available stock digit reaches a first preset digit or not; if the type A cigarettes reach the speed doubling chain in a disc-first mode; if not, the class A cigarettes are conveyed to the speed doubling chain in a scattered disc priority mode.
In one embodiment, the replenishment strategy for class a cigarettes comprises the WMS system polling the available inventory number of the multiple speed chain for a first predetermined time; then the WMS system judges whether the available stock digit reaches a first preset digit; if the task is met, the WMS distributes the trays in a disc-arranging priority mode and generates corresponding tasks, then the WMS issues the tasks to the WCS, and the WCS conveys the class A cigarettes to the speed doubling chain according to the tasks; if the task is not met, the WMS system distributes the trays in a disk scattering priority mode and generates corresponding tasks, then the WMS system issues the tasks to the WCS system, and the WCS system conveys the class A cigarettes to the speed-doubling chain according to the tasks.
In one specific application scenario, the WMS system polls the available inventory number of the double speed chain every two minutes; then the WMS system judges whether the available stock digit is greater than or equal to 30, if so, the WMS system distributes trays in a disc-arrangement priority mode and generates corresponding tasks, then the WMS system issues the tasks to the WCS system, and the WCS system conveys class A cigarettes to a speed-multiplying chain according to the tasks; if the number of the cigarettes is less than 30, the WMS system distributes the trays in a disk scattering priority mode and generates corresponding tasks, then the WMS system issues the tasks to the WCS system, and the WCS system conveys the class A cigarettes to the speed-doubling chain according to the tasks.
The first preset number of bits is set to be 30 because the stacking standard of the cigarette trays is 30 pieces of trays, and therefore, after the trays are taken out of the warehouse, the remaining materials are not required to be returned to the warehouse; when the available stock number meets 30, the whole disc is preferentially allocated, so that the return of the residual materials to the stock can be reduced; when the available stock number does not meet 30, the loose discs matched with the available stock number are preferentially distributed, for example, the available stock number is 15, and the loose discs with the cigarette number of 15 are preferentially distributed, so that the surplus materials are prevented from returning to the stock.
Wherein, the replenishment strategies of the class B cigarettes and the class C cigarettes are divided into two threads,
thread 1: when the available stock digit reaches the first preset digit, the safety stock of each standard cigarette in the class B cigarettes and class C cigarettes is replenished, and the larger the consumption rate of the safety stock is, the earlier the replenishment is.
Specifically, setting triggering conditions for multi-warehouse-through replenishment; when the available stock number of the multi-pass warehouse reaches a trigger condition, sorting all cigarettes in the multi-pass warehouse according to the consumption rate to obtain a priority list of the cigarettes in the multi-pass warehouse, and then replenishing the cigarettes in the multi-pass warehouse according to the priority list; then judging whether the replenishing quantity of the cigarettes reaches a second preset number of bits or not; if the cigarettes reach the warehouse, delivering the cigarettes to the warehouse through a whole-disc priority mode; if not, the cigarettes are conveyed to the multi-pass warehouse in a scattered disc priority mode.
In one embodiment, the WMS system sets a trigger condition for multi-pass restocking; when the available stock number of the multi-pass warehouse reaches a trigger condition, the WMS system sorts cigarettes of various products in the multi-pass warehouse according to the consumption rate to obtain a priority list of the cigarettes in the multi-pass warehouse, and then the WMS system supplements the cigarettes of the multi-pass warehouse according to the priority list; then the WMS system judges whether the replenishing quantity of the cigarettes reaches a second preset number of bits or not; if the task is met, the WMS system distributes the task in a disc-full priority mode and generates a corresponding task, then the WMS system issues the task to the WCS system in batches, and the WCS system conveys the cigarettes to the multi-pass warehouse according to the task; if the task is not met, the WMS system distributes the task in a scattered disc priority mode and generates a corresponding task, then the WMS system issues the task to the WCS system in batches, and the WCS system conveys the cigarettes to the multi-pass warehouse according to the task.
In one specific application scenario, the WMS system is configured to trigger restocking when the available inventory location for the multi-pass library reaches 300; when the available stock number of the multi-pass warehouse reaches 300, the WMS system sorts the cigarettes of various products in the multi-pass warehouse according to the consumption rate to obtain a priority list of the cigarettes in the multi-pass warehouse, and then the WMS system supplements the cigarettes of the multi-pass warehouse according to the priority list; then the WMS system judges whether the goods supplementing amount of the cigarettes reaches 30; if the task is met, the WMS system distributes the task in a disc-full priority mode and generates a corresponding task, then the WMS system issues the task to the WCS system in batches, and the WCS system conveys the cigarettes to the multi-pass warehouse according to the task; if the task is not met, the WMS system distributes the task in a scattered disc priority mode and generates a corresponding task, then the WMS system issues the task to the WCS system in batches, and the WCS system conveys the cigarettes to the multi-pass warehouse according to the task.
The replenishment triggering condition is set to trigger replenishment when the available stock position of the multi-pass warehouse reaches 300, so that the replenishment is triggered for the whole number of pallets to be delivered out of the warehouse (30 pallets are used as a pallet stacking standard, namely, only 10 pallets are needed), the situation that the residual materials return to the warehouse can be reduced, and in addition, the batch task delivery is formed, and the WCS system is convenient to flexibly schedule.
Further, the calculation formula of the consumption rate of each standard cigarette is as follows: safety stock consumption of certain standard = safety stock value of the standard-stock value in the library; certain standard safety stock consumption rate = certain standard safety stock consumption amount/certain standard safety stock value.
When the consumption rate of the cigarettes of each item is calculated according to the formula, the priority of the replenishment is obtained, the replenishment is ordered, the item rule arranged in the first ten is triggered, for example, the calculation shows that the item rule arranged in the first ten is respectively B1, B2, B3, B4, B5, B6, C1, C2, C3 and C4, whether the safety stock consumption of B1 exceeds 30 is firstly judged, if the safety stock consumption exceeds 30, B1 is conveyed to the multi-pass warehouse in a whole disc mode, if the safety stock consumption does not exceed 30, B1 is conveyed to the multi-pass warehouse in a loose disc mode, then whether the safety stock consumption of B2 exceeds 30 is judged, and the replenishment is carried out according to the order of the priority list.
Wherein, the larger the safety stock consumption rate of the product gauge is, the faster the product gauge is consumed, so that the possibility of being out of stock is higher, and the higher the priority of replenishment is.
