In the second- and third-tier cities, the warehousing industry seems to be neglected, but for warehousing and logistics, their value is there again. Really, quite contradictory.
How to calculate how much warehouse I need? First of all, the estimation of the rented warehouse area is related to the storage cost of the enterprise, and then the planning and storage efficiency of the later warehouse. Smart renters will consider the potential value behind this.
There are many renters who want to rent as many warehouses as they think they have. Is this really true? Actually, this is not entirely true. Considering how many warehouses to rent depends on many factors, and the amount of goods is only one of them What is always important is how to manage the warehouse. This has a lot to do with inventory and shelves, and inventory is related to in and out of storage. Having said that, I think a lot of them are fainted, so many variables, How can I determine how large a warehouse is? Please see below: How to calculate the rented area, summarize the following five steps.
Step 1: Estimate inventory
The general average daily inventory calculation method is to add the daily inventory quantity divided by the corresponding number of days. The inventory of a specific warehouse needs to be determined according to the attributes of the goods and the turnover period. For example, if the renter’s product is a refrigerator, then the warehouse may only be able to store 1,000 units, but if the renter’s product is a mobile phone, the warehouse may be able to store 10,000 units. Therefore, first of all, the renter should know what products he needs to store, and how much each product is, so that the renter’s estimated inventory can be calculated.
Step 2: Estimate the floor space of the shelf
Generally, if the customer leases for a long period of time, such as 5 years, and the stacking standard of the goods is relatively standard, you can consider installing shelves to increase the utilization rate of the warehouse and the investment return rate is also good. If the rental period is short, it is not recommended to install shelves, because it is likely that after the customer retires, the shelf type is not suitable for other customers and the monthly depreciation cost of the shelf is also a considerable amount.
Secondly, we need to calculate the shelf height, shelf height = warehouse net height / (goods height + shelf thickness and redundant space). (Note: According to the national standard “Code for Fire Protection of Architectural Design”, the horizontal distance between the vertical lower part of the lamp and the stack should not be less than 0.5m)
Finally, according to the inventory and the shelf height, calculate how many shelves are needed, and then estimate the total shelf area required based on the area of each shelf.
Step 3: Estimate the channel width
The width of the general warehouse aisle can be determined from the following aspects:
According to the turnover of the material, the external dimensions of the material and the transportation equipment in the warehouse, the warehouse with a large material turnover and frequent receiving and sending should be determined according to the principle of two-way operation. B = 2b + C type: B—minimum channel width (m); C—safety clearance, generally 0.9m; b—transport equipment width (including width of transported material, m).
In general warehouses that do not require forklift operation, the channel is generally 0.9m; the width of the channel when using a forklift is generally 1.6 ~ 2m; when using a forklift, it is generally 3.6 ~ 4.2m. Of course, in warehouses where forklifts are used, the smaller the tunnel, the easier it is to operate, and the forklift must also be small. Forklift drivers must be very skilled. If the tunnel is between 3.1 and 4.2m, even novice forklift drivers will have no problems.
Also consider the relevant provisions of the national standard “Code for Fire Protection of Architectural Design”: the distance between the stack and the electrical equipment is not less than 1m; the distance between the stack and the stack is not less than 1㎡; the width of the main passage is not smaller than 2m; Not less than 0.3m; the distance between stack and wall is not less than 0.5m.
Step 4: Estimate the area of the stocking area
The warehouse stocking area refers to picking in the inventory area based on the item’s invoice. After the picking is completed, check the quantity of the item in the stocking area, and check and put it into the shipping area for delivery. The size of the general stocking area is determined based on the average daily cargo volume of the warehouse.
Step 5: Estimate how much warehouse to rent
Warehouse pre-leased area = pallet (shelf) floor area + aisle width + stocking area
