Powering the Industrial Internet of Things, Industrial Big Data Work Order Fact Index Demand Analysis [20]

1: Requirements analysis of work order fact indicators

• Objective: Master the demand analysis of the DWB layer work order fact index table

• path

  • step1: target requirements
  • step2: data source

• implement

  • Target requirements: Based on the work order information, count the number of work orders waiting to be allocated, the number of completed work orders, the number of processed work orders, the response time, the service time and other indicators
