Embodiment Construction
[0045] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0046] Aiming at the above multi-resource partial order task scheduling problem, the present invention proposes a strategy based on master control resource priority (DRP for short).
[0047] 1. Multi-resource POTS model
[0048] Assuming that T is the set of all tasks, each task i∈T can be decomposed into a series of subtasks (i, j). Consider a finite set R of resource types, let c r is the capacity of resource r∈R. For a subtask (i, j), its resource requirements can be defined as If satisfied then the resource Called the master resource of subtask (i,j). Accordingly, define and Respectively, the capacity of the main control resource of the subtask (i, j) and the demand for the main control resource. For a subtask (i, j), its predecessor set and successor set are defined as and
[0049] For a subtask (i, j), the task start tim...
