The warehouse of the enterprise has realized the "three-dimensional storage (the height of 23 layers), unmanned mold handling, warehousing automation, intelligent inventory management, information transmission network".
The warehouse construction investment of the project is 12 million yuan, including 3 million yuan for construction projects (transformed in the original plant), 3 million yuan for pallet manufacturing and 6 million yuan for equipment investment.
The changes brought about by the transformation of the original plant are

1. Save the storage land and construction costs.
The project covers an area of 891 square meters, the design storage mold is 23 floors, 6624 pallets, maximizing the space utilization and improving the unit space storage.The maximum storage capacity of molds is 100,000 sets, and the storage capacity of molds per unit area is 112 sets / square meter.The original plane mold warehouse covers an area of 1344 square meters, the maximum mold storage capacity is about 30,000 sets, and the mold storage capacity per unit area is 22 sets / square meter.
Three-dimensional warehouse more than the unit area of the plane warehouse storage volume increase: (112-22) / 22100%=409%;
Three-dimensional warehouse land saving than the plane warehouse: 1344 / 310-891=3589 square meters;
Land saving: 3598 / 891100%=402%;
According to the minimum land price of each mu of 800,000 yuan, the land purchase cost can be reduced by 80 (3589 / 666.67) = 4.3 million yuan;
Warehouse construction investment according to the cost of 850 yuan per square meter, to reduce the warehouse construction investment of 850 / 100003589 = 3.05 million yuan;
Total storage land and construction costs saved: 4.30 + 3.05 million yuan = 7.35 million yuan.

Second, improve the mold warehousing efficiency and the working time utilization rate of the post-order.

When the manual library is used, the maximum amount of molds every day is 1035 sets, which takes 11 hours.After using the mold automatic three-dimensional warehouse, the average maximum output is 1500 sets, which takes 10 hours.
Improvement of inbound and outbound efficiency (1500 / 10) / (1035 / 2 / 11) -1100%=219%;
Save time for 1 hour (9.09%), and the extrusion workshop can make full use of this time to squeeze products.In addition, although the mold warehouse saves time for 1 hour, because the mold is delivered, under other conditions, the extrusion workshop can increase the net production time of at least 0.5 hours. The extrusion workshop can squeeze at least 7 tons, and 6.5 tons of aluminum alloy can be obtained from aluminum alloy building profiles after surface treatment.If the factory processing cost per ton of profile is 3000 yuan / ton, and calculated by 300 days per year, the increased sales revenue can be 0.36.5300 = 5.85 million yuan.
Third, shorten the storage turnover period.
When using the flat warehouse, the average mold storage period is 34 months.After the automatic three-dimensional mold library was put into use, due to the improved efficiency, the average storage period of the mold is 23 months, which accelerates the turnover.

Four, use fewer people, reduce labor costs.
Using manual warehouse management operation, inventory of 30,000 sets of molds, equipped with 18 warehouse in-out staff.Adopt automatic three-dimensional warehouse, inventory capacity of 100,000 sets, the actual inventory of 40,000 sets, equipped with 13 employees.Compared with the original inventory of 5 people, annual labor costs =54,000 yuan / month. Person 120 = 240,000 yuan / year.
According to the above understood data, after the use of extrusion mold automatic three-dimensional warehouse, the storage link can reduce the land acquisition and civil engineering investment of 7.35 million yuan, and the annual improved economic benefit is 24 + 5.85 = 6.09 million yuan.
