The main objective of the supply Chain Master planning module (master calculates) is to enable the material to flow synchronously throughout the supply chain. The Supply Chain Master planning module provides a way to make medium-term decision making for effective utilization of production, transportation, supply capacity, seasonal inventory and balance of supply and demand. The result of synchronization is that the production and distribution departments can reduce the corresponding inventory levels. Without centralized control of the Master planning module, a large amount of buffer inventory must be added in order to ensure a continuous flow of material. By reducing the degree of change in production and distribution, the Synergy Master plan can reduce these security eases ...

Traditional ...
In MapReduce, shuffle is more like the inverse process of shuffling, which refers to "disrupting" the random output of the map end according to the specified rules into data with certain rules so that the reduce end can receive and process it.
1 Hadoop pipeline improvement in the implementation of the Hadoop system, the output data of the map end is written to the local disk first, and the Jobtracker is notified when the native task is completed, and then the reduce end sends an HTTP request after receiving the Jobtracker notification. Pull back the output from the corresponding map end using the Copy method. This can only wait for the map task to complete before the reduce task begins, and the execution of the map task and the reduce task is detached. Our improvement ...
