Embodiment Construction
[0051] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.
[0052] In the specific implementation of the cloud computing-based bidirectional workflow scheduling method of the present invention, such as Picture 11 As shown, the two-way scheduling method of the workflow includes:
[0053] Step 1. If the workflow is completed on time at the final time, the backward algorithm is used to extract multiple task nodes from the workflow. i The tail node starts to allocate and schedule, and get the workflow after backward algorithm;
[0054] Step 2. After satisfying the multiple task nodes v i Dependency and the final time of the workflow is not exceeded, according to the multiple task nodes v i The earliest start time EST, using the forward alg...
