| 中文摘要 |
| 在制造系统中,必须防止死锁的发生.本文提出了一种在制造系统(带有有限缓冲区)中搜索最优的无死锁调度的算法.为此首先介绍了死锁问题及其图论表示方法,然后在遗传算法的基础上,运用图论算法来保证无死锁的调度结果.为了保证遗传算法生成的调度策略能够满足所要求的约束,运用图论方法选择无死锁个体,或添加缓冲区,从而在基本保证了系统的主要性能指标的同时,得到系统可行的无死锁调度结果.最后给出了一个运用此方法解决死锁问题的实例. |
| 英文摘要 |
| Deadlock must be avoided in a manufacturing system.In this paper,an efficient algorithm for finding an optimal deadlock_free schedules in a Manufacturing System with very limited buffer is presented.First,the deadlock problem and its graph theory representation is introduced.Then based on the effective genetic algorithm (GA) search method,the graph theory is introduced to assure deadlock-free.In order to make the scheduling strategy generated by GA meet the required constrains,a deadlock detection procedure based on graph theory is involved as a condition to select deadlock-free scheduling,or to allocate the buffer.So the feasible scheduling result is obtained while the main performance indicator is guaranteed.Finally,a case is given to demonstrate the effectiveness of this method. |
