Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
With technological advancement, consumption and industry upgrades, new generation logistics exhibit Short-chain (Short-chain), smart (smart) and symbiotic (Symbiosis) 3S features, and warehousing is one of the logistics core links. In order to improve the utilization rate of storage space, a part of areas are planned in the warehouse to be used as a storage area, and high-level shelves such as cross beams, vertical frames and the like are adopted to store the whole tray (the tray is a medium for converting static goods into dynamic goods, can be a cargo platform and is a movable platform or movable ground, and the whole tray at least has the volume utilization rate of more than half); meanwhile, in order to facilitate picking and warehouse-out, a part of areas are planned in the warehouse to serve as picking areas, and low-level shelves such as a baffle plate and a small shelf are used for storing products. If the product is scattered in two areas, the product is called to adopt a storage mode of sorting and separating; if the products are stored in a unified area (generally, a picking area), the products are said to be stored in a unified storage mode. In the prior art, when the storage equipment of a warehouse is planned, namely the storage equipment of a sorting area and a storage area is planned, storage demand difference of different products is not considered, so that the number of the planned storage equipment is higher, and the planning area of an area is not accurate enough. The present invention therefore proposes a method of planning a storage device.
Before planning storage equipment of a warehouse, the method firstly acquires basic information of products in the warehouse and basic information of the storage equipment. Wherein, the basic information of one product may include: the number of the product (i.e., the unique identification of the product), the volume of the product, the number of daily inventory items of the product, the number of daily outgoing items of the product, and the total inventory volume of the product (i.e., the product of the number of daily inventory items of the product and the volume of the product). In the present invention, the daily inventory count (or daily inventory count) may be an average of the inventory count (or daily inventory count) of 30 days, or may be an average of other days according to the actual situation, which is not limited in the present invention. The basic information of the storage device may include: the volume of storage units corresponding to the pick zone storage device and the minimum available volume of the holding zone tray. In addition, the basic information of one product may further include: the length, width, height and weight of the product, etc.
Fig. 1 is a schematic diagram of the main steps of a method of planning a storage device according to an embodiment of the invention. As an embodiment of the present invention, as shown in fig. 1, the main steps of the method for planning a storage device according to the embodiment of the present invention may include:
Step S101: classifying all the products according to the classification information of the products, and calculating the stock volume of a picking area and the stock volume of a holding area of each type of products. The goal of this step is to first sort all the products and then calculate their pick zone inventory volume and hold zone inventory volume separately for each type of product. Wherein, for the A-class products, the stock volume of the picking area refers to the sum of the volumes of the products which are required to be stored in the picking area in the A-class products, and likewise, the stock volume of the storage area refers to the sum of the volumes of the products which are required to be stored in the storage area in the A-class products.
As still another embodiment of the present invention, the classification information in step S101 may include: the delivery level information, the storage device type information, and the storage mode type information. Classifying all the products according to the classification information of the products in step S101 may include: determining, for each product, delivery level information, storage device type information, and storage mode type information for the product; products with the same delivery grade information, storage device type information and storage mode type information are classified into one type. According to the method, the products are classified according to the multiple angles of the product delivery grade information, the product storage equipment type information and the product storage mode information, the delivery quantity, the volume and the storage requirement of the products are considered, and the number of storage equipment can be accurately planned.
In the embodiment of the invention, determining the delivery grade information of the product may include: calculating the ratio of the number of the products to be delivered according to the number of the total number of the products to be delivered in daily life and the number of the products to be delivered in daily life; and determining the ex-warehouse quantity grade information of the product according to the ex-warehouse quantity duty ratio of the product. The product P number of outgoing parts is the ratio of the number of outgoing parts of the product P to the total number of outgoing parts of all the products. In the invention, the information of the delivery quantity grade of the product determined according to the ratio of the delivery quantity of the product can be: firstly, arranging all products according to the descending order of the proportion of the number of the delivered warehouse, then accumulating the proportion of the number of the delivered warehouse, wherein the information of the delivered warehouse of the products with the accumulated proportion meeting the first grade range belongs to the first grade, the information of the delivered warehouse of the products with the accumulated proportion meeting the second grade range belongs to the second grade, and the like, and confirming the information of the delivered warehouse of all the products.
For example, there are 100 products, the number of outgoing pieces per product is calculated first according to the number of outgoing pieces per day and the total number of outgoing pieces per day of all products, then all products are arranged in descending order of the number of outgoing pieces, and then the number of outgoing pieces per 100 products is accumulated in descending order to obtain the information of the outgoing amount class of each product, the specific method may be set: the method includes the steps of (1) accumulating the information of the delivery grade of the product with the number of delivery accounting for 20% or less to be a first delivery grade, (2) accumulating the information of the delivery grade of the product with the number of delivery accounting for 20% or more to be 40% or less to be a second delivery grade, (3) accumulating the information of the delivery grade of the product with the number of delivery accounting for 40% or more to be 60% or less to be a third delivery grade, (4) accumulating the information of the delivery grade of the product with the number of delivery accounting for 60% or more to be 80% or less to be a fourth delivery grade, (5) accumulating the information of the delivery grade of the product with the number of delivery accounting for 80% or more to be 80% or less to be a fifth delivery grade, and (6) taking the information of the delivery grade of the product with the number of delivery of 0 for 30 days to be a sixth delivery grade. Of course, in the present invention, other methods may be used to specifically divide the delivery level of the product, which is not limited in the present invention.
In an embodiment of the present invention, determining storage device type information of a product may include: judging whether a storage unit larger than the total stock volume of the product exists in the storage devices of the sorting area, if so, taking the storage device corresponding to the storage unit with the smallest volume in the storage units larger than the total stock volume of the product as storage device type information of the product, and if not, taking the storage device corresponding to the storage unit with the largest volume as storage device type information of the product. In the invention, the storage area is considered to generally adopt the shelves such as the cross beam shelf or the vertical frame to store the whole tray products, and the storage requirement of the products can be met, so that the storage equipment in the storage area is not particularly divided. In order to facilitate picking and delivering, the storage devices in the picking area may have different sizes, and the goods lattice is the smallest storage unit of the storage devices, which may also be called a goods space, and taking a goods shelf as an example, a 2-5-layer goods shelf has 10 goods lattices. The purpose of this step is to determine the storage device type information for the pickles of the product, which has the advantage that the storage devices for each pickles can be maximally utilized.
In the embodiment of the present invention, determining the storage mode type information of the product may include: calculating the safety stock volume of the product according to the preset safety stock days, the number of the products to be checked out and the volume of the product; determining a custody volume of the product according to the safety stock volume of the product and the total stock volume of the product; judging whether the storage volume of the product is smaller than the minimum available volume of the tray in the storage area, if so, confirming that the storage mode type of the product is the storage and sorting combination, and if not, confirming that the storage mode type of the product is the storage and sorting separation.
In the invention, the safety stock days refer to the days which can meet the picking requirement in the warehouse, for example, 10 products are delivered from the warehouse on average a day, when the safety stock days are 5 days, 50 products are required to be stored in a picking area, and the safety stock days are set to reduce the replenishment frequency. The safety stock volume of the product is the product of the preset safety stock days, the number of the products which are delivered out and the volume of the products. The stock volume of a product is the difference between the total stock volume of the product and the safe stock volume of the product. For example, a safety stock number of days T (e.g., 5 days) is set, and its safety stock volume V is calculated for one product P safe Daily number of products P x volume of products P, volume of stock V keep Total stock volume V of product P safe The method comprises the steps of carrying out a first treatment on the surface of the Judging if V keep Less than the minimum usable volume of a tray, determining the product P as a storage mode of a storage and sorting unit, if V keep And if the minimum available volume of one tray is larger than or equal to the minimum available volume of one tray, determining the product P as a storage mode of sorting separation.
As yet another embodiment of the present invention, calculating the pick zone inventory volume and the hold zone inventory volume for each type of product in step S101 may include: for each type of product, determining an inventory proportionality coefficient of each type of product according to the storage mode type information of each type of product; calculating the preset sorting area inventory volume of each type of product and the preset holding area inventory volume of each type of product according to the inventory proportionality coefficient of each type of product and the average inventory volume of each type of product; judging whether the stock volume of the original storage area of each type of product is smaller than the minimum available volume of the tray of the storage area; if yes, taking the stock volume of the sorting area of each type of product as the average stock volume of each type of product, and enabling the stock volume of the storage area of each type of product to be zero; if not, confirming that the stock volume of the picking area of each product type is the calculated preset picking area stock volume, and the stock volume of the holding area of each product type is the calculated preset holding area stock volume.
In the invention, aiming at the A-class products, if the storage mode information of the A-class products is the storage and picking combination, the inventory proportion coefficient of the A-class products is confirmed to be: the stock proportion of the picking area is 100 percent, and the stock proportion of the storage area is 0 percent; if the storage mode information of the A-class products is sorting separation, calculating the inventory proportionality coefficient of the A-class products as follows: sorting area inventory ratio = safety inventory number/turnover number 100% (wherein, safety inventory number and turnover number are preset according to practical situation, the invention is not limited thereto), custody area inventory ratio = 1-sorting area inventory ratio; then, according to the obtained inventory proportion coefficient of the A-class products, the inventory volume V of the picking area of the A-class products is obtained pick And custody area inventory volume V reserve The method comprises the steps of carrying out a first treatment on the surface of the If V reserve The minimum available volume of the tray is smaller than that of one storage area, the class A products are all planned to be stored in a storage mode of storage and sorting, and all the class A products are stored in a sorting area; if V reserve If the minimum available volume of one tray is greater than or equal to the minimum available volume of one tray, the class A products are all planned to be stored in a separate storage mode, and the volume distribution is still the stock volume V of a picking area pick And custody area inventory volume V reserve 。
Step S102: and counting the total sorting area inventory volume and the total storage area inventory volume by utilizing the sorting area inventory volume of each product and the storage area inventory volume of each product.
Step S103: and planning the demand of different storage devices according to the total volume of the stock of the picking zone and the total volume of the stock of the holding zone.
As yet another embodiment of the present invention, planning the demand for different storage devices according to the total pick zone inventory volume and the total hold zone inventory volume at step S103 may include: planning the demand of storage equipment of the picking area according to the total inventory volume of the picking area and the type information of the storage equipment of the product; and planning the demand quantity of storage equipment in the storage area according to the total stock volume of the storage area.
