本文针对水库设计供水期保证电量计算方法存在的问题，和发电与灌溉用水等矛盾，应用系统工程多目标决策，和增量动态规划与分析相结合的方法，提出了能使电力系统基建投资省、保证电量大、和灌溉用水多的综合利用效益高的优化方案；同时还得出了具有长期予报的水库供水期最优调度的一般规律，应用该规律能迅速方便地得出最优方案。

While the strict integrity policy of Biba's model can be used to maintain integrity of data in computer systems, the integrity labels of both subjects and objects in a system are always kept static in SIP, which might lead to denial to some non-malicious access requirements and hence decreases the compatibility of applications Dynamic enforcement of this policy is presented, which can increase compatibility of software while keeping system integrity as strictly as SIP can The implementation of...

Biba模型中的严格完整性政策能够有效地保证数据的完整性，但是该政策中主体和客体的完整性标记都是静态不变的，这会限制进程的一些原本合理的活动，从而降低应用程序的兼容性。提出严格完整性政策的动态实施方案，并给出该方案在基于Linux的安全操作系统RFSOS中的实现。该方案既可以保证系统的完整性，又能提高系统的兼容性。实验证明，这种方案对系统的整体效率的影响小于1%。
