基于相关度的同步协同设计冲突消解策略

为解决同步协同设计技术所面临的设计资源冲突,提出了一种基于相关度的标准满意度冲突消解策略.在分析设计决策冲突产生原因的基础上,以学科领域相关度为依据,针对同步协同过程中的设计权限,应用标准满意度的评价方法,建立了冲突消解策略模型,来提高协同设计的效率和实时性.在多学科领域协同设计过程中得到了应用,并分析了该冲突消解策略的优越性.     

电弧炉电极调节系统的满意度PID控制

电弧炉电极调节系统是具有强非线性及随机扰动的系统。在满意度PID控制方法基础上,对电弧炉电极调节系统进行了基于反馈线性化的满意度PID控制设计研究,并进行了单指标约束和多指标约束情况下满意度PID控制的仿真,验证了此控制方法的适用性,这对电弧炉电极调节系统及同类非线性系统的研究有重要意义。     

基于人机交互的热轧动态调度

针对热轧动态调度问题,在深入分析其生产过程中扰动因素基础上,提出了各种扰动事件的处理策略,给出了基于人机交互的处理流程.在此基础上开发了基于人机交互的热轧动态调度系统,该系统主要包舍扰动识别模块、在线调整模块、模型优化模块、调整板坯顺序模块和系统管理模块.源于钢厂实际生产数据的仿真结果表明,该人机交互平台能够快速有效地处理各种扰动事件,获得与原调度尽量一致的新调度方案,保证了热轧生产过程的连续与稳定.

Quantified constraint satisfaction problems (QCSPs) are an extension to constraint satisfaction problems (CSPs) with both universal quantifiers and existential quantifiers.In this paper we apply variab...     

Chance-constrained model predictive control for spacecraft rendezvous with disturbance estimation

A robust Model Predictive Controller (MPC) is used to solve the problem of spacecraft rendezvous, using the Hill-Clohessy-Wiltshire model with additive disturbances and line-of-sight constraints. Since a standard (non-robust) MPC is not able to cope with disturbances, a robust MPC is designed using a chance-constrained approach for robust satisfaction of constraints in a probabilistic sense. Disturbances are modeled as Gaussian allowing for an explicit transformation of the probabilistic constraints into simple algebraic constraints. To estimate the distribution parameters a predictor of disturbances is proposed. Both robust and non-robust MPC control laws are compared using the Monte Carlo method, which shows the superiority of the robust MPC.     

模糊逻辑在电子商务商品推荐系统中的应用

在电子商务平台中提供有针对性的商品推荐机制以帮助用户快速准确地找到所需的商品非常重要。综合满意度是指根据用户关注的商品的不同属性的满意度在商品推荐中所占的权重不同,对商品的各属性满意度进行加权运算得到的满意度度量值。根据商品综合满意度的排序进行商品的推荐可以提高推荐的准确性。商品满意度是一个模糊的概念,提出了使用模糊逻辑来处理商品满意度的方法,并提出了一整套基于满意度的商品推荐机制。论文介绍了一个基于商品满意度的电子商务商品推荐系统的框架,重点介绍了其中的基于模糊逻辑的商品属性满意度处理方法和基于商品综合满意度的商品推荐规则,并给出了一个商品推荐的模拟实例。     

Impact of personality and intelligence on job satisfaction of assembly line and bench work - an industrial study

A study of the impact of machine-paced (M/P) and self-paced (S/P) work on job satisfaction of 28 female industrial assembly workers was evaluated in which M/P work was confounded with simplified work and the S/P job was confounded with enriched tasks. Results indicated the following:

1. 1. Over three-quarters of workers were more satisfied in S/P jobs, while only less than one-quarter were more satisfied in M/P jobs.

2. 2. The 16PF personality test effectively predicts (0·88 multiple correlation) the satisfaction ratios of M/P to S/P jobs.

Impact of an organizational control policy on absenteeism, performance, and satisfaction.

Examined the impact of an organizational control policy based on the concept of "legal compliance" with established organizational norms on 2 behavioral measures--absenteeism and performance--and 2 attitudinal measures of satisfaction. The control policy was experimentally manipulated in each of 2 experimental groups totaling 297 undergraduates. In one group, a compulsory attendance policy followed by a noncompulsory policy was employed, while in the other the sequence of administering the policies was reversed. Attendance, performance, and satisfaction measures were used as criteria in analyses of variance. Results indicate that a control policy based on legal compliance significantly improved attendance and performance and did not alter satisfaction levels.

DVD租赁优化方案

在线租赁是信息时代发展的必然趋势。在租赁过程中，网络经营者主要关注DVD的预测、购买和分配。本文提出了简单随机抽样、分类预测和关联预测等三种方法进行需求预测。针对问题一，利用需求预测得到观霜DVD的人数服从二项分布，并计算出多种可靠度下购买DVD的数量。以会员的最大满意度为目标函数，建立一个整数规划模型，得到问题二的分配方案。并计算出前30位会员的分配结果。在问题三中，我们考虑到60％的会员由于两次租赁而导致DVD可重复利用，因而，采用了两阶段购买的策略，在每个购买阶段都建立了双目标整数规划，从而得到的购买量比原来网站拥有量小，并且会员的满意度达到99．38％，本文最后还给出了考虑归还DVD周期的情形下购买与分配的模型。
