The invention relates to the technical field of warehouse management, in particular to a control system for a cloud warehouse in a cloud logistics environment.
Background
The rapid development of electronic commerce expands the coverage of electronic commerce activities and increases the logistics model cost of delivering goods from a goods source of the traditional merchant. In such a development environment, the response time is also becoming longer and longer as merchants become more distant from customer locations. As orders become more personalized, complicated, and differentiated, the cost of response time to the warehouse becomes higher and higher. Therefore, it is particularly important for e-commerce vendors to develop a reasonable inventory control strategy. In order to respond to the customer demand in time, deliver the product instantly, reduce the delivery cost and enlarge the service coverage of the seller on the premise of meeting the transaction guarantee, a plurality of electronic commerce sellers select 'warehouse distribution', namely warehouse distribution in part of central cities in the whole country.
Warehousing is the middle link of the whole supply chain, and the upstream is connected with manufacturing industry, and the downstream is connected with transportation and distribution. With the rapid development of technologies such as cloud computing, cloud manufacturing, internet of things and the like, the traditional warehousing industry gradually develops towards cloud logistics and cloud storage. A cloud storage refers to a storage that is not individually owned by a single merchant or manufacturer but is commonly used by multiple merchants or manufacturers. Under the background of the age in which the e-commerce is popular, the cloud storage is the main stream of supply chain storage.

The basis for judging whether goods are marked is to judge whether the profit of the supply chain of the goods can be improved after the goods are marked. Thus, in this embodiment, it may be determined whether to mark the good by determining the magnitude relationship of (the maximum value of) the first profit and (the maximum value of) the second profit, namely:
order to
Thereby calculating a boundary value point l of the marking cost for marking the goods0. Therefore, specifically, the step S130 may be:
