Embodiment 1

[0036] The invention provides a task scheduling method based on cloud manufacturing, figure 1 It is a flowchart of an embodiment of the task scheduling method based on cloud manufacturing in the present invention, such as figure 1 As shown, the task scheduling methods include:

[0037] Step 101, acquire the task set to be executed at the current moment and the required resources of each task in the task set.

[0038] Step 102, judging whether all the required resources of each task exist in the resource library, and obtaining a judging result.

[0039] Step 103, when the judgment result indicates that the required resource does not exist in the resource library, transfer the task flow corresponding to the required resource to the task set to be executed at the next moment.

[0040] Step 104, when the judgment result indicates that the required resource exists in the resource pool, divide the task into a first-level hierarchy according to one of the index parameters, and foll...

Embodiment 2

[0048] The invention provides a task scheduling method based on cloud manufacturing, figure 2 It is a flowchart of an embodiment of the task scheduling method based on cloud manufacturing in the present invention, such as figure 2 As shown, the task scheduling methods include:

[0049] Step 201, acquire the task set to be executed at the current moment and the required resources of each task in the task set.

[0050] Determine that the number of all tasks to be executed within a time window T is K, and establish a set of tasks to be executed M T ={m 1 ,...,m i ,...,m k}(i=1,2,...,k), all tasks in the set are in the first level L1 of task scheduling.

[0051] Step 202, judging whether all the required resources of each task exist in the resource library, and obtaining a judging result.

[0052] Step 203, when the judgment result indicates that the required resource does not exist in the resource library, transfer the task flow corresponding to the required resource to t...

Abstract

The invention discloses a method and a system for task scheduling based on cloud manufacturing. The method for task scheduling based on cloud manufacturing comprises: obtaining a to-be-executed task set of current time, and demand resources of each task in the task set; when the demand resource does not exist in a resource library, converting a task flow corresponding to the demand resource to a to-be-executed task set of next moment; when the resource library has the demand resource, according to one of index parameters, performing first layer grading on the task, if a plurality of tasks exist in a same grade, transferring the tasks to a next layer and continuing to perform grading according to another scheduling index, and executing the tasks in sequence from high grade to low grade, until all tasks are executed. The task scheduling method eliminates conflicts occur in a task scheduling process using a layer-by-layer grading method, and task scheduling efficiency is improved.

Description

technical field [0001] The present invention relates to the field of cloud manufacturing, in particular to a task scheduling method and system based on cloud manufacturing. Background technique [0002] Emerging information technologies such as cloud computing and the Internet of Things are integrated with advanced manufacturing models and technologies to form cloud manufacturing. Cloud manufacturing is a network that uses the network and cloud manufacturing service platform to provide users with various on-demand manufacturing services. Create new models. In the cloud manufacturing environment, it is necessary to allocate matching virtualized manufacturing resources for various manufacturing service requirements (ie tasks) of users. Usually, in a time window, there will be multiple users and multiple tasks. How to schedule these manufacturing service tasks belonging to different users and different characteristics, so that the manufacturing service tasks can be effectively...
