面对当前不确定性风险的增加和错综复杂的世界局势,越来越多的企业正在寻求构建多元化的供应链渠道和企业营销策略。以海澜之家和Boohoo两家服装企业为例,基于供应链运营参考模型(SCOR)对其供应链渠道选择策略和运行现状进行分析,探究形成如此差异的原因。最后,通过分析讨论,提出聚焦客户特质细分市场、借助RFID技术和一键上门物流服务等对策,以便为服装企业优化供应链渠道提供借鉴和参考。  相似文献

基于健康状态评估的军用电站预先维修对提高其可靠性、安全性有着重要意义,采用基于CNN-MD的评估方法,对军用电站健康状态进行评估。建立CNN军用电站健康状态识别模型,通过用不同的状态样本训练模型,可使模型识别和输出健康状态类别;再引入MD算法,计算不同状态下样本与健康样本的MD距离,并将其归一化为健康指数,即可进一步量化军用电站健康评价结果。以某型军用电站人工模拟不同健康状态的工况获取实验数据,通过模型能对正常、退化和注意三种状态进行有效区分,并得到量化评价健康指数0.6为正常状态的临界阈值,0.6以下即为退化以下状态的具体量化评估值,验证了所提方法的有效性。该方法通过CNN和MD结合,可实现军用电站健康状态定性与定量评估目的,为开展预先维修提供依据。  相似文献

秦国农业发展成就的取得与其文化传统密切相关。关中地区"好稼穑、务本业"的社会风尚奠定了秦国农业发展的文化基础;秦文化重功利的价值取向使秦国的农业激励政策发挥出了最大效能;宗法观念淡薄则使个体小家庭生产这种最适应生产力发展水平的经营方式在秦国得到了最彻底的推行。  相似文献

Evaluation of value of irrigation water is essential for supporting policy decision making relating to investments in the irrigation sector, efficient allocation of irrigation water and water pricing and for crafting policies to compare the variable impacts of water reform within and across sectors of the economy. This paper asks the question of how much an established irrigator would pay for water and at what price farmers planning to expand the area they have under irrigation would consider paying for the right to access water. An analytical framework is developed to estimate the net present value of both annual and perennial agricultural activities in the Murrumbidgee catchment. Using these estimates the total value of water used in Murrumbidgee catchment is estimated. An aggregate water supply curve is derived for the catchment from where water may be acquired from irrigators for environmental flows.  相似文献

Food quality ratings can be used for product differentiation and strategic marketing. This article develops a differentiation measure based on the cross‐entropy of two distributions for speciality coffees. It examines whether quality ratings achieve their objectives for speciality coffee supply chains. The estimation, using e‐auctions data, indicates that the quality rating is more informative in the Cup of Excellence (CofE) relative to the Q auction. To determine significance, a statistical test for comparing the information measure across different e‐auctions and segments of the quality rating was developed. The significant difference between the two auctions is not a surprise as the auctions trade coffee lots of different volumes and the quality evaluation is more important in the case of the CofE, with its jury of renowned coffee experts. The total cross‐entropy measure of product differentiation shows that the 100‐point quality rating does not carry the same information content and meaning in the two different e‐auctions and their respective supply chains. The cross‐entropy measure of product differentiation is shown to be a good indicator of the information and the value created throughout the speciality food supply chain.  相似文献

This paper jointly examines performance and conditions surrounding membership as determinants of the decision to stay or leave an R&D consortium. Hypotheses were developed for performance and, by drawing from power dependence and transaction cost theories, for conditions surrounding membership. Analysis of survey questionnaire data from 184 member organizations of U.S.-based R&D consortia indicates that performance and the conditions of knowledge-related involvement, network ties, learning, and alternatives are related to the decision to stay in or leave. These results provide limited support for power dependence but are more consistent with transaction cost theory. Subsequent analyses revealed an interaction between performance and membership conditions, suggesting performance leads to the conditions of membership, and that the continuity decision for a poorly performing consortium differs from that for one performing well. © 1997 John Wiley & Sons, Ltd.  相似文献

Being international and involving numerous organizations as the basic nature, maritime supply chains are exposed to various natural and man-made risks. This paper aims to develop an original quality function deployment approach to enhance maritime supply chain resilience, taking both customer requirements and maritime risks into consideration. The empirical analysis is carried out through in-depth studies of three major shipping lines and their respective major shippers. The top three resilience measures are contingency plan, monitoring and maintenance, and supply chain relationship management. The study also unveils the relatively low visibility and integration in maritime supply chains.  相似文献
