Description

Multi Deep Pallet Shuttle system and management method for the system

The present invention relates to an MDPS system, and more particularly, to an operation method of an MDPS system and an MDPS system capable of efficiently loading and unloading cargo by dividing a loading space.

Logistics refers to the flow of water from producer to consumer with less physical distribution. In general, the concept of distribution includes activities to transfer goods and services from producers to consumers and to create the utility of place, time, and ownership. Logistics, on the other hand, defines logistics as a place that creates utility of place and time, excluding transactions that satisfy the utility of ownership.

This includes both the process of transporting, unloading, storing, and packaging the produced goods, and the process of distribution of materials such as distribution processing and transportation infrastructure. In addition, information distribution concepts such as communication infrastructure and information network are all included here. Logistics therefore refers to the parts related to national key industry activities such as transportation infrastructure, communication infrastructure, and transportation, storage, unloading, packaging, distribution, processing and information functions that companies can manage in their own way.

The cargo storage warehouse is a place where cargo is temporarily stored. The cargo storage warehouse keeps cargo that is not immediately distributed and then releases it when needed. The cargo storage warehouse, which is a member of the logistics system, can evaluate the efficiency of the logistics system based on the time taken to load the cargo into the warehouse and the time taken to release the loaded cargo. If you can not only load the cargo in the warehouse in a short time, but also get the cargo loaded in the warehouse in a short time, this will be the best logistics system.

Rift up the cargo with the current cart to travel a certain distance, and load the cargo to the place. Therefore, according to the space in which cargo is loaded, the cart must be moved directly. The cart is not only slow but also has to be operated by humans. Another disadvantage is that the load space is reduced by that much.

In addition, when loading the cargo using the cart, it depends on the performance of the cart, but when the loading place is more than two floors there is a disadvantage that the loading of the cargo is impossible or difficult. Even when the loaded goods are shipped, the loading process is performed in the reverse order of the loading process.
