供应商是每个生产性企业的基础,也是企业核心管理的重点.回顾和评析了国内汽车零部件供应商评价的研究情况,发现国内大多数专家学者仅对企业供应商总体绩效评价进行打分评估,用加权平均的结果来辅助供应商的选择.但是对于供应商的决策问题,这种方法很难做到很好的辅助决策分析.本文引入模糊聚类方法,确定了以产品合格率、准时交货率、订货满足率、产品性价比、总资产收益率、总资产周转率、资产负债率、库存周转率、成本费用利润率、基本运输费用率、技术人员比例、研发资金投入比率、顾客满意率作为汽车零部件供应商绩效的评价指标体系,通过针对于一般评价问题运用的模糊综合评价方法,来仔细、深入的研究发现,模糊聚类分析的方法,更适合于企业供应商选择一类的问题.参考有关的汽车零部件供应商评价指标,建立了新的评价指标体系,然后遵循基于模糊聚类算法,按照系统的编程思想来构建模型的仿真系统.  相似文献

This study examines firms’ use of partner selection and formal contracts as key approaches to manage transaction risk in interfirm relationships. We specifically examine the impact of transaction characteristics that generate transaction risk on (1) the importance placed on different selection criteria in the choice of collaboration partner, and (2) the complexity of contracts used to manage the collaboration. Survey data support that when confronted with greater risk from the transaction context, firms place more emphasis on trust-based and reputation-based selection criteria for partner choice and develop more complex (i.e., more inclusive and specific) contracts to manage the collaboration. Furthermore, our results show that partner selection mediates the effects of transaction characteristics on contract complexity, consistent with the argument that the information acquired during the partner selection process in response to risk facilitates the design of contracts to manage risk.  相似文献

This paper discusses the theory behind ex ante governance decisions in inter-organizational relationships and uses an explanatory case study involving an inter-firm relationship between two European airlines to empirically assess the theoretical propositions. The case study complements existing literature by providing a comprehensive explanation of opportunism-based ex ante governance decisions. It deconstructs opportunism, links such behavior to unique governance responses and discusses the ex post effects of ex ante governance decisions in light of the necessary development of trust and relational governance mechanisms. In this context, it also takes account of differences in bargaining power between the two partners and examines the “control strategy” employed by the dominant partner. The paper offers further insights into the influence of bargaining power on governance decisions by illustrating how cooperating partners can address ex ante power differences. An interesting finding from this case study is the fact that the more powerful of the two partners deliberately relinquished the advantages associated with its ex ante privileged position. It accepted a governance structure that virtually equalized positions to motivate its weaker partner to participate and stimulate the development of trust.  相似文献

This article gives an overview and introduction to the Martingale approach to multi-period (dynamic) portfolio decisions. While Martingale pricing techniques have long been used with considerable success in the pricing of derivatives and financial assets in general, their potential to improve the practice of dynamic portfolio decisions is not sufficiently recognized yet. This article shows that the approach is, in principle, not difficult to implement for readers equipped with standard option replication techniques if markets are sufficiently “complete” in order to provide investors with the relevant information about the pricing of financial risks. The article provides a practical guide to implement the basic features of the approach in a binomial framework.  相似文献

The majority of existing artificial intelligence (AI) studies in computational finance literature are devoted solely to predicting market movements. In this paper we shift the attention to how AI can be applied to control risk-based money management decisions. We propose an innovative fuzzy logic approach which identifies and categorizes technical rules performance across different regions in the trend and volatility space. The model dynamically prioritizes higher performing regions at an intraday level and adapts money management policies with the objective to maximize global risk-adjusted performance. By adopting a hybrid method in conjunction with a popular neural network (NN) trend prediction model, our results show significant performance improvements compared with both standard NN and buy-and-hold approaches.

This paper uses a differential neural network (DNN) to describe the behavior of daily closing values of German DAX and USA S&P 500 stock indices between July 3, 2000 and January 13, 2012. Then, by the use of DNN a four-week forecast is performed of the daily closing values of these indices, from January 16 to February 10, 2012. The results obtained confirm that the differential neural networks can become one of the most powerful and accurate tools to predict future values of financial assets.  相似文献
