知识创新是一个复杂的、隐含规律与秩序的演化过程,文中运用混沌理论进行了知识创新的演化趋势和规律探讨。将知识创新系统看作复杂系统,分析知识创新的混沌特性,建立基于创新能力的知识创新的混沌动力学模型。在模型建立的基础上,进行知识创新的模拟和动态演变规律的分析,以创新的状态和系统的演化为依据,将知识创新分为非时间连续的四类阶段：创新匮乏阶段、初步创新阶段、规律创新阶段和混沌创新阶段,与渐进性创新和突破性创新进行了对应分析,并基于本文的模型从知识创新角度分析了知识创新系统中渐进性创新与突破性创新的统一。 相似文献

专利密集型企业原始创新知识搜寻作用机理 《科学学研究》2022,40(7):1303-1313
研究将原始创新知识搜寻划分为前瞻型知识搜寻与反应型知识搜寻,探究知识搜寻对原始创新知识创造的影响及差异,以及知识积累的中介作用和原始创新意志的调节作用。研究结果表明:前瞻型知识搜寻对原始创新知识创造具有显著正向影响,反应型知识搜寻与原始创新知识创造间具有倒U形关系。知识积累在前瞻型知识搜寻对原始创新知识创造的影响中起到了部分中介作用,知识积累在反应型知识搜寻对原始创新知识创造的影响中起到了完全中介作用。原始创新意志可以正向调节前瞻型知识搜寻对原始创新知识创造的影响,且原始创新意志显著调节了反应型知识搜寻与原始创新知识创造之间的倒U型关系。研究结果为专利密集型企业实现原始创新知识创造而选择适宜的知识搜寻策略提供了理论依据和实践参考。 相似文献

Many organizations have made substantial progress in solving the year 2000 computer problem, while many others lag perilously behind. With the year 2000 deadline looming ever closer, this article examines several key issues, including the nature of the year 2000 problem itself, its potential to do harm, the progress that organizations have made to date on this issue, and factors that have worked to inhibit or facilitate organizational responses to this problem. An ethical analysis of the year 2000 problem is presented that reveals that both top management and IS professionals have an ethical responsibility to act on this issue. Organizations are urged to make the completion of their year 2000 problem efforts a top priority, because it is their responsibility and it serves as an investment for the future. 相似文献

In this paper, a class of fuzzy optimal control problem called fuzzy Bang-Bang (FBB) control problem is revisited. The FBB control problem aims at finding control inputs which transfer the states of an uncertain dynamical system to the origin in a minimum time. Since the conditions and/or parameters of the dynamical system are uncertain, the FBB control problem is a challenge task. To address the problem, we first introduce the concepts of the granular integral and derivative of fuzzy functions whose domain is uncertain. In addition, the notion of granular partial derivative of a multivariable fuzzy function whose variables are fuzzy functions with uncertain domains is presented. Then, we propose a theorem which is proved to be applicable to the FBB control problem. Moreover, taking the relative-distance-measure fuzzy interval arithmetic and horizontal membership functions into consideration, we further give complementary theorems to ensure that if the problem has a solution, then the controller assumes its boundary values. The simulated results confirm this theoretical conclusion. These findings may enrich our insight of the behavior of the uncertain dynamical system subjected to the FBB control problem, and guide to predict the uncertain trajectories. 相似文献

Rice drying synthesis is an essential operation that has to be done carefully and cost-effectively. Rice is harvested at high moisture content and hence must be dried within 24 h for safe storage. However, improper drying can cause fissuring in the rice grain, and thus greatly reduce its market value. Multi-pass drying systems are therefore used to gradually bring moisture content to desired level.The problem of rice synthesis, considered in this study, seeks the configuration of units and their corresponding operating conditions that maximize rice quality. This problem is formulated as a mixed-integer dynamic optimization problem. The integer part of the problem reflects process alternatives while the dynamic part originates from nonlinear differential-algebraic equations describing the drying behavior of a rice grain.Clearly such a formidable problem is not easy to solve. Hence, we propose an approach that makes use of two algorithms: a genetic algorithm to search for the best configuration of units and a control vector parameterization approach that optimizes the operating conditions for each configuration. We demonstrate the effectiveness of the approach on a case study. 相似文献

In an era of rapid technological advances, individuals have access to a plethora of open and closed forms of problem solving. We introduce and test a framework that compares different forms of problem solving and determines how individuals make choices among them. Our analyses of 4,556 problems solved by 398 individuals reveal that high problem complexity and strong implicit social norms of open exchange increase the probability that individuals will seek external solutions rather than solve the problems themselves. Our analysis also shows that they prefer individual experts (contacted directly or via open call) over aggregated crowd knowledge. We also find that strong implicit social norms of open exchange weakened the positive impact of complexity on the probability of solving problems externally. Interestingly, this effect is more subtle when the use of aggregated crowds is compared with individual experts: while strong implicit social norms strengthen the positive impact of problem complexity when experts are contacted directly, they otherwise weaken the use of open call experts. We discuss and examine the nuanced effects between problem complexity and social norms of open exchange. The study contributes to a stream of the open innovation literature that uses a problem solving perspective to better understand under what circumstances certain forms of problem solving are utilized, and it then combines it with a novel empirical setting based on real-life experimental data. 相似文献

在企业的日常管理活动中,中层管理者是承上启下的关键所在,企业的战略实施、员工激励、团队建设等管理问题无不与之密切相关。但是,对中层管理者的激励却成为企业持续经营过程中面临的一个难题,集中表现在中层管理者离职率上升、工作积极性下降等现象上。从契约理论的角度审视此问题,心理契约破裂是问题产生的关键,以此为基础建立柔性化的人力资源激励体系是解决问题的路径选择。 相似文献

多目标遗传算法NSGA—Ⅱ是解决0／1背包问题^[1]的有效算法,但是它还存在一定的缺陷,当0／1背包问题的规模较大时,这种方法很难收敛到Pareto最优边界,因此解的分布性不是很好,解集也很难收敛。针对此问题,提出基于ε支配的MOGA来求解0／1背包问题,通过实验验证该算法在求解分布性上优于NSGA-Ⅱ。 相似文献
