The first one, in the logistics link to ensure the safety of goods. The use of block chain technology in logistics industry can optimize resource utilization and improve efficiency, and can record and transfer

In order to avoid such conflicts, we should not putReDimused as a declaration statement, and only as statements that redefine the size of an array. - theNote To change the size of the array that the variant contains, you must explicitly declare the variant variable before attempting to change its array size.The following example would like to use ReDim Preserve

Iamlasong VBA programming achieves random output without repeating. The random function in VBA is RND, and the random function in worksheet is Rand. The difference between the word and can be remembered. The RND value range is [0, 1). It indicates a random number between 0 and 1, which contains 0, but does not contain 1. 1. Usage Syntax: RND [(number)]If the valu

The mall registers EDI, the bank -- the mall selects the producer -- the producer selects the Logistics Company 2. The mall generates an order-the producer accepts the order-the producer sends a delivery notice to the logistics company-the

Visualization of logistics management has always been a challenge in the world's logistics management, especially for large international express delivery companies. Although bar code technology and RFID technology can help people solve many problems, however, due to various reasons, the phenomenon of goods loss still exists, however, it is almost impossible for people to accurately search for a real image
