A dynamic test task scheduling method and scheduling platform based on a greedy grouping strategy

Abstract

The invention discloses a dynamic test task scheduling method and scheduling platform based on a greedy grouping strategy, and belongs to the field of automatic test system dynamic task scheduling. The scheduling platform comprises a user login module, an instance adding and maintaining module, a database module, a test instance import module, a scheduling algorithm module and a scheduling resultdisplay output module; and obtaining information of the test task set, randomly selecting N test tasks in a real number coding mode to equally divide the test tasks into Gn groups, and carrying out inner layer optimization to obtain an optimal solution of each group. And decoding the optimal solution of each group to obtain an optimal scheduling scheme, and connecting all the optimal scheduling schemes end to end to obtain a fitness value fn. And repeating the above method until the outer layer reaches the set number of initial populations, performing iterative optimization to obtain an optimal solution corresponding to the minimum fn, decoding the optimal solution to obtain a static scheduling scheme, responding to the dynamic event, and outputting a dynamic scheduling result and a scheduling Gantt chart. The understanding quality is improved, and the system is convenient to maintain and upgrade.

Description

technical field [0001] The invention belongs to the field of dynamic task scheduling of an automatic test system, and in particular relates to a dynamic test task scheduling method and a scheduling platform based on a greedy grouping strategy. Background technique [0002] The traditional automatic test system research focuses on the field of static scheduling, which solves the problem of sequencing and allocation of several test tasks on several instruments (resources). Among them, a task may have multiple options to complete the test, each option consists of one or more instruments, and there are certain timing constraints between tasks. The scheduling goal is to arrange various test tasks to the corresponding test instruments, and efficiently arrange the order of the task test process and the time to start the test. [0003] In the actual working process of the automatic test system, various unexpected emergencies are inevitable, such as instrument failure, new task arri...
