To be competitive in contemporary turbulent environments, firms must be capable of processing huge amounts of information, and effectively convert it into actionable knowledge. This is particularly the case in the marketing context, where problems are also usually highly complex, unstructured and ill-defined. In recent years, the development of marketing management support systems has paralleled this evolution in informational problems faced by managers, leading to a growth in the study (and use) of artificial intelligence and soft computing methodologies. Here, we present and implement a novel intelligent system that incorporates fuzzy logic and genetic algorithms to operate in an unsupervised manner. This approach allows the discovery of interesting association rules, which can be linguistically interpreted, in large scale databases (KDD or Knowledge Discovery in Databases.) We then demonstrate its application to a distribution channel problem. It is shown how the proposed system is able to return a number of novel and potentially-interesting associations among variables. Thus, it is argued that our method has significant potential to improve the analysis of marketing and business databases in practice, especially in non-programmed decisional scenarios, as well as to assist scholarly researchers in their exploratory analysis.  相似文献

The open source model provides a valuable framework for collective knowledge production and dissemination. Open knowledge networks and other cooperative strategies (classified as open source discovery initiatives) are enabling biopharmaceutical companies to access disembodied knowledge‐based resources critical to downstream drug development. The objective of these cooperative strategic alliances is to preserve the downstream technological opportunities for multiple firms. When upstream discovery research cannot yield commercial products and when the costs associated with excessive upstream competition are too high, companies jointly benefit from cooperative knowledge production and open knowledge dissemination. An analysis of 39 open source initiatives (consortia) provides us with information on: the likely participants in such initiatives, the focus of knowledge production activities, the characteristics of the knowledge generated, and the management of joint knowledge assets. Based on this analysis, we use game models to understand the decision to participate in such strategic alliances better. Our game models provide a simple but elegant framework for understanding the impact of changing knowledge structures on the payoffs associated with cooperation and defection in knowledge production, and therefore on behaviour.  相似文献

In its introduction this paper discusses why marketing professionals do not make satisfactory use of the marketing models posed by academics in their studies. The main body of this research is characterised by the proposal of a brand new and complete methodology for knowledge discovery in databases (KDD), to be applied in marketing causal modelling and with utilities to be used as a marketing management decision support tool. Such methodology is based on Genetic Fuzzy Systems, a specific hybridization of artificial intelligence methods, highly suited to the research problem we face. The use of KDD methodologies based on intelligent systems like this can be considered as an avant-garde evolution, exponent nowadays of the so-called knowledge-based Marketing Management Support Systems; we name them as Marketing Intelligent Systems. The most important questions to the KDD process-i.e. pre-processing; machine learning and post-processing-are discussed in depth and solved. After its theoretical presentation, we empirically experiment with it, using a consumer behaviour model of reference. In this part of the paper, we try to offer an overall perspective of how it works. The valuation of its performance and utility is very positive.  相似文献

为了形成智能化异构多无人机协同突防策略,提出了基于多智能体异步模仿深度确定性策略梯度算法的异构多无人机协同突防方法。首先,基于典型DDPG方法,采用异步并行框架进行改进,提高经验的收集效率。其次,分别构建基于专家经验知识的牵引性奖赏函数和基于任务结果的描述性奖赏函数。再次,通过分阶段训练后,使得深度神经网络产生的协同突防策略能够快速达到专家经验知识水平后,进一步提高对抗水平。最后,在仿真实验中,构建了异构多无人机协同突防环境,对改进方法和典型DDPG方法的对抗效果进行了对比。实验结果表明,MA2IDDPG方法能够有效产生多无人机协同突防策略,并且在训练阶段表现更为稳定且对抗效果更优。所设计的创新性MA2IDDPG方法框架可有效应用于无人机群控制领域,特别是对异构无人机群的智能控制方法研究具有重要参考意义。  相似文献

'Expert Systems' or intelligent knowledge-based computer systems can be expected to have a considerable impact in the near future on the dissemination and use of technical expertise in practical situations. The potential benefits of such an approach to decision-making in applied science domains, for example, in anti-corrosive coating selection, are considerable. This paper argues, therefore, that a premium must be placed on such a system's performance as a communicator.
The structure and behaviour of a classical 'production system' are briefly described, and the communicative ability of such a system is analysed. This critical examination of a production system's question-answering capabilities highlights the inherent restrictions which the structure of this kind of system places on its explanatory and justificatory powers. An outline design for a less inhibitive structure is presented.
It is argued that the form in which the system provides 'answers' after the completion of a problem-solving session, may not yield sufficient appropriate information to the user, and a possible alternative view of a 'solution schema' is proposed.  相似文献
