Description

Technical field [0001] The invention relates to the field of engineering applications, in particular to a method for predicting total completion time driven by industrial big data. Background technique [0002] The so-called "total completion time" means that in the scheduling problem, the scheduled object is generally a collection of N jobs (Job), which is called an instance. Use I for instance, J j Represents the jth artifact among them. Each artifact J j Each has its own arrival time (Release time) R j And processing time P j (Processing time). In the scheduling plan S, the start time is S j (Starttime), the completion time is C j (Completion time), and the total completion time is ∑C j (Total completion time). The so-called "total completion time prediction" refers to the use of scientific mathematical models to predict the total completion time of tasks or projects. [0003] In engineering applications, there is a widespread demand for total completion time prediction. For...
