In order to give some references to the design and manufacture of ship hydraulic propulsion,module selection formulas is proposed for engine management.
介绍了液压推进船舶的原理和功率传递及控制方式,给出柴油机与液压泵站、液压泵站与液压马达、液压马达与螺旋桨之间的选择规则,并建立船舶的动力装置仿真模型用于验证模块的选择,证明了此规则的通用性。
Considering synthetically the stochastic factors like processing time,arrival rate and due date of the job,combination performance of dispatching rules and routing rules was analyzed under different breakdown rates by simulation and the most optimized combination of dispatching rules and routing rules were given under each performance measure.
综合考虑了工件的加工时间、到达率和交货期等随机因素,仿真分析了不同故障率下调度规则和路径选择规则组合的性能,并给出了每种性能评价指标下最优的规则组合。
Given a society of finite individuals and the set of two alternatives,we define the majority rule as a social choice rule and give some sufficiency and necessity conditions when the social choice rule is the majority rule.
在给定的有限的参与人集合及两个备选对象集的条件下,就社会选择规则定义了一种简单多数规则,并给出了一社会选择规则是简单多数规则的几个充要条件。
Given a society of finite individuals and any set of alternatives, we discuss the sufficiency and necessity condition or sufficiency condition when the social welfare function is a majority rule; Given a society of finite individuals and finite set of alternatives, we define the majority rule as a social choice rule and give some sufficiency and nece.
本文第一章将就两个备选对象定义的Asan的弱路径独立性和Woeginger的亚社会可约性概念推广到任意备选对象集,在给定的有限的参与人集合及任意备选对象集的条件下,讨论了一社会福利函数是简单多数规则的充要或充分条件;第二章在给定的有限的参与人集合及有限的各选对象集的条件下,就社会选择规则定义了一种简单多数规则,并给出了一社会选择规则是简单多数规则的几个充要条件。
