Exact algorithms for the feedback length minimisation problem EI Scopus SSCI SCIE
期刊论文 | 2019 , 57 (2) , 544-559 | International Journal of Production Research
Abstract&Keyword Cite

Abstract :

Planning the sequence of interrelated activities of production and manufacturing systems has become a challenging issue due to the existence of cyclic information flows. This study develops efficient exact algorithms for finding an activity sequence with minimum total feedback length in a design structure matrix. First, we present two new properties of the problem. Second, based on the properties, we develop an efficient Parallel Branch-and-Prune algorithm (PBP). Finally, the proposed PBP is further improved by adopting hash functions representing activity sequences, which is referred as hash function-based PBP. Experimental results indicate that the proposed hash function-based PBP can find optimal solutions for problems up to 25 interrelated activities within 1 h, and outperforms existing methods. © 2018 Informa UK Limited, trading as Taylor & Francis Group

Utilizing multi-source data in popularity prediction for shop-type recommendation EI SSCI SCIE
期刊论文 | 2019 , 165 , 253-267 | Knowledge-Based Systems
Abstract&Keyword Cite

Abstract :

It is important for an investor to determine the most suitable shop type (e.g., restaurant, cafe) given a location. Traditionally, investors determine shop types based on their subjective judgments and perceptions. However, insufficient information and cognitive limitation often lead to flawed decisions and increase investment risks. With advances in information technology, multi-source heterogeneous information and big data analytics can be utilized to provide support for making such a decision. In this paper, we propose a novel shop-type recommendation method that suggests a suitable shop type based on multi-source information collected from a business review site, a location-based navigation system and a mobile carrier. Specifically, our method first constructs the location-type matrix to alleviate the problem of incomplete data and models the location profile by considering internal and external features simultaneously. In particular, a hybrid similarity model is proposed to integrate the location profile and the commercial structure into a unified framework. Then, a location-based collaborative filtering method is developed to predict shop popularity and suggest a suitable shop type. Finally, we demonstrate the effectiveness of our method compared to several benchmark methods by applying it to a real-world dataset from China. © 2018 Elsevier B.V.

Moderating role of financial ratios in corporate social responsibility disclosure and firm value SCIE SSCI Scopus Pubmed
期刊论文 | 2019 , 14 (4) , 0215430 | PLOS ONE
Abstract&Keyword Cite

Abstract :

This study investigates the link between corporate social responsibility (CSR) disclosure for multi-stakeholders and financial performance of a firm through accounting-based activities for CSR. A dataset of Chinese non-financial firms listed on the Shanghai Stock Exchange from 2008 to 2012 is taken from the China Stock Market & Accounting Research database. The study compares different financial ratios of CSR disclosure and non-disclosure firms. Moreover, the financial ratios of CSR disclosure firms also compare with the industry averages. The results suggest that the financial of CSR disclosure firms are better than both CSR non-disclosure firms and industry averages. These financial ratios ensure the claim of a firm that they are socially responsible toward multi-stakeholders. Further, the same financial ratios are used as moderator variables between CSR disclosure for multi-stakeholders (independent variable) and firm financial performance (dependent variable). The relationship between CSR disclosure and firm value is moderated by the financial ratios. The moderation effect of financial ratios is rarely used in the literature of CSR disclosure and firm value.

Abstract :

软件产品的经验性和强网络效应使得企业往往依靠免费的基础产品积聚人气,再通过收费的增值产品或服务来盈利.现有免费增值策略相关研究多局限于垄断情况,对多个企业之间的竞争交互鲜有探讨.基于产品网络效应和消费者偏好差异,本文构建Hotelling模型研究了双寡头企业免费增值策略博弈均衡及其影响因素.结果表明:若网络效应相对较强,企业都应采用免费增值策略;若网络效应相对较弱,都不采用;若网络效应相对处于中等水平,存在"都不采用"和"都采用"两种可能的均衡结果,但前者情况下双方企业都能获得更大利润.另外,消费者对企业之间的水平差异越敏感,对免费版本的质量要求越高,企业采用免费增值策略的动力越弱,"都不采用"区域扩大,而"都采用"区域缩小.

Abstract :

新产品的市场接纳具有很大不确定性,传统投资理论并不适用于新产品投资.针对新产品投资中的产能投资,研究了垄断企业和有成本差异的竞争企业制定短周期新产品的产能投资时机与规模策略.给定企业"早"和"晚"两个投资时机可供选择,定义"早"投资时,企业只知道新产品市场规模的期望和方差;"晚"投资时,企业知道新产品真实的市场规模.垄断企业进入市场之前无法进行销售信息的收集,只会选择"早"投资或者不投资,给出其选择"早"投资的条件、最优产能投资规模及最大期望利润.有成本差异企业竞争的情形可以分为四种,分别给出四种情形下的最优产能投资规模及最大期望利润,并通过比较各情形下两企业的最大期望利润给出最优的产能投资时机策略.

Scheduling Interrelated Activities Using Insertion-Based Heuristics EI SSCI SCIE Scopus
期刊论文 | 2018 , 65 (1) , 113-127 | IEEE TRANSACTIONS ON ENGINEERING MANAGEMENT
SCOPUS Cited Count: 1
Abstract&Keyword Cite

Abstract :

The issue of scheduling interrelated activities is important and of particular concern to design managers. One tool that helps us to solve this issue is the design structure matrix (DSM) which can explicitly represent the information dependencies among interrelated activities. Based on the DSM method, this study presents effective approaches for sequencing interrelated activities with the goal of minimizing total feedback length, which is a good approximation for reducing project completion time. First, we prove two new properties of the problem, and develop an insertion-based heuristic. Second, the proposed heuristic is further improved by combing it with simulated annealing and genetic algorithm. Computer experiments show that our approaches outperform existing heuristics, in that with similar settings, our approaches often produces better solutions.
