The Scheduling of Project Time,Cost and Product Quality

2010 Chinese Control and Decision Conference

作者： wuliang peng,Zhongliang Zhang,Zhaofu Tian School of Economics and Management,Shenyang Ligong University,Shenyang 110168

＜正＞To optimze the product quality as well as project cost,a discrete time/cost/product quality trade-off model used for product development projects was presented on the theoretical basis of resource constrained project scheduling problem（RCPSP）.According to the characteristics of product development project,the project cost is calculated by the price of resources,and the quality function deployment method（QFD） is used to quantitatively calculate product quality. A brand and cut algorithm was presented to solve the *** the model and its algorithm were verified by a project case.

项目群中的多个项目存在着更加密切的关联关系,典型表现为项目之间的紧前关系约束。本文考虑多项目之间存在紧前关系约束且在分布式环境下竞争有限共享资源的情况,提出了一种面向项目群管理的分散式资源约束多项目调度问题。该问题的最大特点是在保持单项目独立调度的前提下,在项目群中考虑多个项目的关联关系执行优化调度,实现多目标优化和共享资源分配。基于快速非支配遗传算法进行改进,设计了一种两阶段求解算法。第一阶段运行在单项目层,以工期和共享资源需求最小化为目标,对每个单项目进行双目标调度;第二阶段运行在项目群层,根据单项目的求解结果,在项目紧前关系约束下,进行项目群双目标优化调度,确定项目群工期、共享资源投入和资源分配的最优配置集合。通过大量的计算仿真,验证了算法的改进效果。本文所提出的方法通过单项目和项目群的分层调度,实现了单项目个体优化和项目群全局优化的统一。

为提高煤矿企业应急管理的规范性和自动化程度,解决应急预案和应急决策的衔接问题,提出了一种基于网络计划技术的煤矿企业应急管理方法。该方法首先以应急预案的可重构性为基础,对应急预案进行规范化处理,采用任务网络计划技术将各个应急措施作为任务形成应急预案计划,然后将应急预案计划作为应急处置计划的模板,综合考虑突发事件的类型、具体情况、应急处置的资源条件及适度的个人偏好,在应急预案计划的基础上进行修正,迅速形成完整、规范的应急处置计划。实际应用表明,该方法可提高应急预案和应急执行计划的结构化和数字化水平,能够实现应急预案和应急执行计划的无缝衔接。

分布式调度是智能制造的新模式,急需新的调度方法来应对动态多变的市场需求。针对分布式置换流水车间问题,采用逆调度方法优化,通过最小调整加工参数,使得尽可能保证原排序的情况下调度最优。以最小化调整加工时间为目标,建立流水车间逆调度数学模型,针对逆调度问题特征,在遗传算法的框架下提出一种混合遗传优化算法。首先,基于逆调度参数可调的特征,提出基于工序的小数机制双层编码方案,能够实现参数的调整,保证可能解;提出改进启发式方法和基于规则的方法相结合的混合初始化方法;其次,采用适合问题特征的交叉、变异操作执行搜索;为协调全局搜索与局部搜索能力,设计局部搜索策略和学习机制的双种群协同搜索策略。为验证算法性能,基于问题实例采用三种算法进行比较,并且进行统计分析,其结果表明所提算法能更有效求解分布式流水线逆调度问题。
