城市智慧供应链发展指数构建及其应用

在新一轮科技革命和产业变革浪潮的带动下,智慧供应链正在快速发展,与之相关的城市智慧供应链发展也成为当前供应链研究领域中的重要问题。然而,传统的供应链发展评价指标体系难以直接应用到智慧供应链评价中。为此,本文从企业视角和区域视角出发,从城市智慧供应链基础设施情况、人力资源投入情况、资金投入情况、企业创新情况、供应链效率和效益6个维度构建了中国城市智慧供应链的发展评价体系,设计了基于改进的TOPSIS方法的评价方法,并进行了中国城市智慧供应链发展指数评价,为城市管理部门量化智慧供应链发展水平提供了方法依据。     

A data envelopment analysis game theory approach for constructing composite indicator: An application to find out development degree of cities in West Azarbaijan province of Iran

Data envelopment analysis (DEA) model has been widely applied for constructing composite indicator and finding development degree of areas. With the increasing number of indicators, the distinguish power of DEA model is decreased. In this paper, in order to increase distinguish power in DEA model and find out the fair weights in cross-efficiency DEA context, the game theory approach is applied. The DEA-Game theory approach is used to rank cities in West Azarbaijan province of Iran. First, 68 suitable indicators are determined and then, the indicators are classified in 10 sectors. Finally, the actual data for year 2013 is gathered and DEA-Game theory model is applied. To verify and validate the DEA-Game theory approach, simple additive weighting (SAW) and TOPSIS methods are used and the results are compared. The Spearman correlation between DEA-Game, SAW and TOPSIS models shows that the DEA-Game theory model is suitable for constructing the composite indicators.     

Assessment of CSR based supply chain performance system using an integrated fuzzy AHP-TOPSIS approach

The objective of this research was to identify Corporate Social Responsibility (CSR) criteria as well as propose and prioritise the alternatives to improve the supply chain performance system of an organisation. To meet the objective, firstly, CSR-based criteria, sub-criteria and alternatives were identified based on the literature review and discussion with the field experts, taken from automobile industries located at the Delhi region of India. Then, kappa statistics has been applied to check the internal consistency between identified criteria and sub-criteria. After finding the evidence of internal consistency, a hierarchical-type model has been developed and analysed using a multi-criteria decision-making as an integrated fuzzy analytical hierarchy process (AHP) and a fuzzy technique for order performance by similarity to the ideal solution (TOPSIS) approach. To make the results more robust and feasible, a sensitivity analysis has also been performed.     

Evaluating museum websites using a combination of decision-making theories

ABSTRACT

The role of museums is very important in cultural and heritage tourism, and a museum website plays an important role in attracting visitors, both physically and online. Therefore, these websites must be evaluated to ensure that their goals are met. However, the evaluation of a website is complex and is often omitted during the website’s life cycle, despite its importance. To simplify this process, this paper presents a framework for evaluating museum websites. The framework, based on an inspection method, is called the inspection evaluation method (IEM). This method uses criteria proposed by several researchers in a review of the different evaluation experiments for museum websites that have previously used an inspection method. IEM, different from all other methods reviewed, uses a combination of an analytic hierarchy process with a technique for the order of preference by similarity to an ideal solution for combining these criteria. The framework was applied to evaluate and rank the websites of five museums known worldwide. This combination uses the advantages of two multi-criteria decision-making theories and reduces their disadvantages.     

Evaluating the transformation of China's resource-based cities: An integrated sequential weight and TOPSIS approach

The transformation and development is an inevitable problem for resource-based cities (RBCs). In the process of transformation, cities in various cities, regions, resource types and development stages are having shown commonality and uniqueness. However, little work has been done on the horizontal comparison between RBCs. This paper evaluates the transformation level of 81 RBCs in China from 2006 to 2017 and investigates the transformation effect of cities in different regions, different dominant resources and different development stages. The comprehensive index system incorporating economy, society and environment is established by using the improved TOPSIS method. The results indicate that the transformation effects of most RBCs are between 0.400 and 0.800. Generally speaking, the transformation effects of four economic regions are on the rise, especially in the western region, with an increase of 17.626% from 2006 to 2015. The transformation effect of RBCs in the eastern region is the highest, while that in the northeast is the worst. Regeneration cities’ transformation effect is the best, reaching more than 0.70 in 2017. The transformation effect of growth cities is the worst, but the growth rate is the highest from 2006 to 2015. There is a rising trend of the transformation effects for oil-based cities and coal-based cities, while the transformation effects of iron-oriented cities and rare earth-oriented cities are not obvious.

风险偏好视角下工程项目风险分担研究

合理的风险分担机制能够提高工程项目管理绩效,然而,目前的风险分担机制主要以“理性人”为假设,忽略了对于项目参与方风险偏好的关注。旨在建立嵌入合同双方风险偏好的风险分担决策方法,通过文献研究,构建了风险分担评价指标体系,并结合模糊集理论和TOPSIS技术,设计了风险分担定量模型。在该方法中,承包商风险偏好包含在评价指标体系中,业主风险偏好通过派生的三角模糊数予以表示。最后,通过实证案例对该方法的实用性和有效性进行了验证,研究成果为实现工程项目合理风险分担提供了理论支持。     

电网企业节能减排效果分析模型及应用——基于改进TOPSIS法

全球气候变化及能源危机是人类社会发展所面临的重要挑战,如何保障能源供给,促进经济、社会和环境的协调发展成为亟待解决的问题.电网企业作为能源消耗和污染物排放的主要产业,其节能减排效果将对我国节能减排措施的实施起着举足轻重的作用.近年来,智能电网的发展为清洁能源的接入并网与低碳用电技术的运用提供了重要支撑,它不仅能够实现发电侧的清洁生产,而且能够通过需求侧管理实现用户侧的节能减排.本文将从发电侧、供电侧及用电侧三个角度分析构建电网企业节能减排贡献效果的评价指标体系,利用熵权法修正指标权重,然后利用TOPSIS法构建了电网企业节能减排贡献效果评价模型,算例结果表明改进的TOPSIS法适用于从不同角度评价电网企业节能减排的贡献效果.
