基于变电站主设备服役周期长、运维费用高、故障风险大、残值高等特点,在变电站主设备全寿命周期费用结构分解的基础上,结合动态成本计算模型,重点构建了变电站主设备LCC招标评标动态模型,并应用于变电站主设备的招标评标打分计算。最后,通过特高压工程1000KV变压器招标采购算例,验证说明了LCC招标评标动态模型能全面反映变电站主设备的全寿命周期成本费用,有助于从源头上统筹处理好安全、效能和周期成本三者的关系,有助于最优采购方案的选取。  相似文献

A conceptually based taxonomy of 22 distinct forms of e-shopping vehicles is proposed. A modification of the UTAUT and UTAUT2 models is introduced to explain how vehicles are interrelated in regard to consumer reliance upon them for their e-purchasing. A survey of over 1,000 millennial university students, 697 Chinese and 306 US, revealed strong support in both samples for the hypothesized six dimensional pattern underlying consumer vehicular reliance. Further, differences between Chinese and US samples lay not in the nature of the dimensions, but rather in the strength of reliance upon each dimension. Thus, the study demonstrates the utility of the concept/measure of shopper vehicular reliance, VPR (Vehicle Purchasing Reliance) for both practitioners and scientists. In cross-national comparisons, observed differences between samples in strength of reliance supported four of five hypotheses predicated on previously established national distinctions a) in trust and b) in the cultural value of individualism-collectivism.  相似文献

This paper re‐examines the long‐run purchasing power parity (PPP) relationship for nine Asian countries relative to the USA and Japan during a period containing significant structural breaks. The relevance of considering structural breaks in PPP tests is demonstrated by utilizing the Johansen et al. (2000) procedure that allows for up to two pre‐determined structural breaks. Using conventional tests without considering breaks, one is able to reject the null of no cointegration for only four countries. The Johansen et al. procedure clearly demonstrates the importance of allowing for structural breaks and provides strong support for long‐run PPP for all the countries, regardless of the base country, except in the case of the Philippines vis‐à‐vis Japan. The Hansen–Johansen parameter constancy test indicates stability for all the countries except the Philippines relative to the USA and Malaysia relative to Japan.  相似文献

Stakeholders’ demands for product sustainability redefine the focus of corporate purchasing strategies from the traditional concern with financial performance to considerations of ‘triple bottom line’ viability. This adds to the complexity of managing interorganizational relationships and poses a question regarding corporate ability to effectively leverage suppliers over environmental and social performance of supplied goods. Since it is not clear what type of purchasing relationship is more favorable for greening a product supply, the current paper aims to investigate how food retailers manage their relationships with suppliers in order to influence the environmental and social performance of procured goods and improve the availability of sustainably produced supply. The research is based on two case studies of Swedish supermarkets and supplementary semi‐structured interviews with Swedish, British and Danish supermarkets. The results of the study contribute to the existing body of academic knowledge in the field of sustainable supply chain management by developing a typology of sustainable purchasing relationships with detailed insights into the nature of collaborative practices, structure of incentives, sustainability ambition, and approaches to verification of compliance. The study has also revealed the dependence of sustainable purchasing relationships on the characteristics of the procurement context, namely the presence of well‐established sustainability certification schemes, perceived by purchaser's situation with availability of sustainability certified supply and purchaser's interpretation of the state of power dependence in relationships with suppliers.

Collectively, small hotels constitute a significant solid waste management (SWM) problem. Little research has focused on the SWM practices of small hotels. In the United Kingdom, much of the solid waste generated by small hotels goes to landfill. This study uses a constructionist approach to investigate SWM issues in small hotels in a local authority in Wales and examines the role of the public sector in helping small hotels manage their solid waste effectively. The results revealed that only a minority of small hotels were considering the adoption of sustainable SWM practices, either because hoteliers felt negatively about sustainable SWM alternatives or perceived challenges – an issue which necessitates government intervention. At the time of this study, the public sector provided only very modest services to enhance SWM practices. This study proposes a best practice model for the public sector to encourage small hotels to manage their solid waste effectively, in order to reduce or even eliminate waste for landfill. Local authorities' support is required to make waste management hierarchy options more accessible to small hotels and should incentivise better waste management through increasing the gap between the costs of landfill and recycling waste.  相似文献

Abstract

Purchasing behaviors of tourists for Tennessee-made food products were examined. Amount of units purchased, approximate expenditures, and where products were purchased were recorded. Over 95% of the individuals purchased Tennessee-made food products for themselves and 64% purchased the products as gifts. The majority of the products were purchased at speciality stores or tourist sites. Products most often purchased included candies/confections and chocolates. Quality of the products was the most important factor in the decision to purchase. The average tourist visiting Tennessee purchased 4.9 items and spent $34.60 on these products. Processors of state-made products and tourism departments need to market the quality and uniqueness of their products at speciality shops and tourist sites.  相似文献
