基于惩罚机制的产学研合作演化博弈分析

产学研合作对构建国家创新体系和实现向创新驱动型经济体转变具有重要的作用,而在新形势下,多方参与的产学研合作模式成为主流,为保证各方的利益及合作顺利进行,在长期合作中需要有一定的约束惩罚机制。首先建立多人多策略的演化博弈模型,并对各情况下的收益进行分析计算;然后建立惩罚机制,并把惩罚和收益关联起来,调整各方不同情况下的收益;之后使用粒子群优化算法进行模拟仿真,摒弃传统固定好数值的静态模拟方法,考虑"支出-收益"比例和"惩罚-收益"比例的动态数值分析,模拟得出惩罚约束存在下多人多策略的产学研合作演化情况;最后,得出结论并提出相应的对策建议。

混沌理论与构建ISD的新思考

从混沌理论出发，在对混沌理论应用于ISD原因分析的基础上，得出混沌理论对构建新ISD的启示，这对于拓宽ISD研究视野，发挥人的主体能动性是很有利的。     

高保真语音录放系统的设计

本课题研究的目的就是用单片机控制ISD语音芯片实现语音现场录制及回放。本课题把这一系统以家用留言机的形式做了出来,可以很方便地进行语音留言,为系统录制不同语音即可实现多项功能,例如录入公交站各站语音段即可为公交实现语音报站。因为系统用的是ISD语音芯片的直接语音模拟存储,从而实现了语音的高保真输出。为一些对语音质量要求比较高的场合提供高保真输出。     

How can organisations learn: an information systems development perspective

This article sets out to argue that organisations can learn but that they cannot do so in their own right without infrastructural support. This article further examines the notion that individuals in organisations also require the cognitive participation of the organisation itself as a learning entity to learn. The close reliance and affiliation required between individuals and organisations to enable their learning from one another are discussed. In continuation of this, specific examples are provided through the industry sector of information systems development (ISD) projects to illustrate of how organisations can learn. Finally, the question of how one identifies organisational learning is analysed. Following on from the ISD and its use in the analogy of organisational learning, the article discusses an organisational empirical research project currently being undertaken by the authors, which utilises blogs. Though there are many potential organisational learning connotations associated with blogs, they could be perceived as a type of information system. The ongoing research being undertaken with the company using the blogs will attempt to identify indicators of learning at the individual, group and organisational levels. The significance of the issues explored in this article lies in the fact that it addresses an ISD approach to study how an organisation learns, and why this perspective is useful towards understanding the process of organisational learning. This article contributes to the organisational learning debate through an illustrative industry example of ISD projects. In doing so, we wish to argue that though individual learning can occur in ISD projects, the collective nature of projects primarily engenders the interpretive aspect of organisational learning. We further believe that it is the interactive nature of an ISD project that allows an organisation to learn in tandem with project members as exemplified through the stages of a project life cycle. We feel that this article contributes to the ISD and organisational learning literature in terms of linking both concepts together.
