Scheduling algorithm for AND/OR precedence constrained tasks based on solving the set-cover problem

WANG Tao,LIU Da-xin (College of Computer Science and Technology,Harbin Engineering University,Harbin 150001,China)  
This paper systematically describes the model of an AND/OR network as well as a feasibility testing algorithm for AND/OR precedence constrained task scheduling.On the basis of the set-cover problem,it is shown that the problem of minimization of completion time for AND/OR precedence constrained tasks is NP-complete.A heuristic algorithm is proposed to solve this category of problems.An example is given showing that the algorithm can obtain better scheduling performance and an optimal AND-only graph.This shows that the introduction of graph optimization to real-time precedence constraint task scheduling is an efficient approach to solving problems in scheduling precedence constrained tasks.
