我国应开征燃油税的简要经济学分析

在我国开征燃油税是治理整顿公路运输中“乱收费”问题的需要,也是节约能源、落实科学发展观的必然要求。从经济学角度分析,开征燃油税无论是对燃油消费者还是燃油供应者,都会产生一定的影响。因此,开征燃油税需要根据不同的需求主体和供给主体,制定相应对策,以避免可能出现的负面影响。

Reprint of “Planning in feasible region by two-stage target-setting DEA methods: An application in green supply chain management of public transportation service providers”

To meet green supply chain management’s requirements of a company and its transportation service providers (TSPs), it is essential to set clear, achievable, and realistic targets. This paper proposes two data envelopment analysis (DEA) approaches to find targets for two-stage network structures. The objective of proposed approaches is to plan in feasible region. The feasible region specifies bounds to ensure targets are within current operational capacity of TSPs. Applying the approaches to set targets for 24 TSPs lead to different results. However, proposed models ensure that the TSPs would be efficient in their current capacity.     

Multi-objective supplier selection and order allocation under disruption risk

We formulate a multi-objective MILP model to find the optimal choice of suppliers and their order quantity allocation under disruption risk. Suppliers are evaluated and ranked, based on the preference values obtained using a hybrid fuzzy AHP-fuzzy PROMETHEE. Multi-objective Particle Swarm Optimization is then applied to yield a set of Pareto-optimal solutions for the choice of suppliers and their order allocation. Numerical experimentation suggests that the supplier failure probability affects the expected total cost more than supplier flexibility and loss cost. Sensitivity analysis is performed on the failure probability, the output flexibility, and loss cost of the suppliers.

Exploring the impact of a supplier portal on the buyer-supplier relationship. The case of Ferrari Auto

This article concentrates on the relationship between companies and their suppliers with a specific focus on the impact that information and communication technologies (ICTs) have on industrial (business to business) purchasing processes. After reviewing the extant literature, we classify the potential impact of ICTs on the buyer-supplier interactions into three main categories, i.e. impact on buyer-supplier relationship, impact on purchase process efficiency and impact on logistics process performance. Whilst scholars generally agree on the impact ICTs may have on buyer-supplier exchanges, they have not investigated concurrently all of these three impacts to understand their comparative relevance and the context in which this comparative relevance may change. In order to redress this gap in the literature our research study focuses on a particular form of ICT solution - supplier portals - and takes a supplier (rather than buyer) perspective. We explore empirical evidence from a single customer-multiple supplier case study, that of the Ferrari Auto supplier portal. Our study leads us to contend that suppliers view such portals as offering far more significant benefits to their relationship with customers than to the improvements in purchase process efficiency or to the performance of buyer-supplier logistics processes. We conclude with a short discussion of the main managerial implications and suggestions for future research.     

基于模糊粗糙集的供应商绿色评价体系研究

随着可持续发展战略意识的深入人心,对供应商进行绿色评价将成为绿色供应链管理的核心之一.文章运用模糊粗糙集理论构建了一个三维供应商绿色评价体系,在该理论指导下对贯穿于供应商评价与选择全过程的评价指标进行"绿化",从中进行数据挖掘,实现了对供应商的科学评价和正确选择.     

A novel option contract integrated with supplier selection and inventory prepositioning for humanitarian relief supply chains

This paper proposes a novel two-period option contract integrated with supplier selection and inventory prepositioning. A two-stage scenario-based mixed possibilistic-stochastic programming model is developed to cope with various uncertainties. The first stage's decisions include supplier selection and capacity reservation level at each supplier/period and the level of inventory prepositioning. Furthermore, decisions regarding the time and exercised amount are made in the second stage. Applicability of the model is validated through a real case study. Finally, several sensitivity analyses are conducted to examine the effect of important parameters on the solutions to gain useful managerial insights.     

供应商参与技术创新的效能提升机制研究

整合供应商开展技术创新具有低风险和快速成功的优势,但由于供应商未必会全力以赴地面向制造企业需求实施创新,供应商参与技术创新的效能往往难以达到预期效果。使用供应商创新性反映供应商参与技术创新的实际效能,从社会资本理论视角,探究制造企业通过结构、关系和认知形式的社会资本获取供应商授予的优先客户地位,进而激发供应商创新性的规律。基于186个中国制造业样本的实证研究表明,制造企业获取供应商授予的优先客户地位对激发供应商创新性的效果显著;制造企业与供应商之间的社会资本积累能够促使供应商授予其优先客户地位,但由于结构、关系和认知维度社会资本之间存在内在差异,作用机制有所不同。
