Vendor’s performance evaluation is an important subject which has strategic implications for managing an efficient company. However, there are many important criteria for prospering company. These criteria may contradict together. In other words, while a criterion is improved, the other may worsen. Indeed, similar to manufacturing manager in global market, purchasing manager who has significant practical implications deals with this issue. The vendor selection problem (VSP) is obviously affected by the complexity and uncertainty due to the lack of information associated with related business environment of countries in a global market. On the other hand, in the automotive industry which plays an important role in the worldwide market, these decisions will be exacerbated by increasing the outsourcing and opportunities. There are varieties of techniques, from simple weighted scoring methods to complex mathematical programming, for handling VSP.In this study, we propose a new cost efficiency data envelopment analysis (CE–DEA) approach with price uncertainty for finding the most cost efficient unit. Potential uses are then illustrated with an application to automotive industry involving 73 vendors in Turkey. 相似文献

This paper proposes a super-efficiency model for measuring aggregative efficiency of multi-period production systems. The proposed model does not require any information on price data or preferential weighings of inputs and outputs over multiple periods and able to measure aggregative efficiency of multi-period production systems. The model computes efficiency score of each decision making unit (DMU) in each period. At the same time, the model classifies DMUs and ranks the fully efficient ones. Besides, the model provides a new technique for reducing the computational complexity of a recently introduced model. The proposed method is illustrated with a numerical example and proves to be effective and practical. 相似文献

利用正交试验和DEA博弈交叉效率模型,研究了质量特性与参数隐式函数关系下的混合稳健设计模型。首先设计质量指标和成本指标,将其作为试验指标对变量(即未知的参数和容差)进行正交试验;然后将每组试验方案看作一个决策单元,分别将质量指标和成本指标作为DEA博弈交叉效率模型的输出指标、输入指标,构建DEA混合稳健设计模型,评价出质量-成本效率相对最高的组合方案(即最佳参数、容差组合);最后用案例验证了该方法的可行性和有效性。结果表明,该模型能够有效解决质量特性与参数隐式函数关系下的混合稳健设计问题,其工程适用性更为广泛。 相似文献
