A pro-active and collaborative approach to reverse logistics—a case study

Reverse logistics is considered to be the key for re-manufacturing and sustainable development. It has gained increasing attention in the last decade and has been a new frontier of strategic management. One of the driving forces for firms to adopt the reverse logistics practice is cost saving from reverse logistics activities. Another motivation to put reverse logistics forward is probably due to environmental impacts on non-returnable materials. Reverse logistics, however, may require cooperation of more than one company and hence it is generally poorly managed due to self-interest of different companies. Therefore, a pro-active and collaborative approach to reverse logistics is demanded. This paper reports a case study of using returnable packaging materials between a manufacturer and an original equipment manufacturer (OEM) supplier. A cross-company team was established to pursue the goal of the reverse logistics project. Tangible and intangible benefits of reverse logistics from this case study are presented in this paper.     

Six things to manage--Designs

Transportation in reverse logistics (RL) plays a significant role and has impact on overall RL performance. Efficiency, effectiveness and impact are the distinct components of RL transportation. Balancing these components requires the implementation of an effective performance measurement (PM) system. The perspectives of balanced scorecard have been used where enterprises can link their performance to their transportation practices, which do not provide an understanding of the RL transportation operating objectives and the developing strategies through an analysis of stakeholders. This article proposes the comprehensive PM of transportation system, which is multi-angle perspective for RL enterprises. Recognising the multiple criteria nature of the problem, this article uses analytical hierarchy process methodology in order to find an overall comprehensive performance index, which is critical to the success of the RL transportation operations to assist logistics managers, researchers, transportation planners and decision-makers.     

Partner selection for reverse logistics centres in green supply chains: a fuzzy artificial immune optimisation approach

The design of reverse logistics networks has now emerged as a major issue for manufacturers, not only in developed countries where legislation and societal pressures are strong, but also in developing countries where the adoption of reverse logistics practices may offer a competitive advantage. This paper presents a new model for partner selection for reverse logistic centres in green supply chains. The model offers three advantages. Firstly, it enables economic, environment and social factors to be considered simultaneously. Secondly, by integrating fuzzy set theory and artificial immune optimisation technology, it enables both quantitative and qualitative criteria to be considered simultaneously throughout the whole decision-making process. Thirdly, it extends the flat criteria structure for partner selection evaluation for reverse logistics centres to the more suitable hierarchy structure. The applicability of the model is demonstrated by means of an empirical application based on data from a Chinese electronic equipment and instruments manufacturing company.     

Forum : The roadblock for travel communications

Reconciling the convenience of computerised transactions with privacy protection has become an important problem for the travel and tourist industries — particularly in those countries where privacy legislation has not yet been enacted. The American Express company has been working on the problem and has been lobbying in favour of privacy legislation while adopting a self-imposed code to protect the company's card-holders. This article is based on a speech given to the European Travel Commission on 6 November 1980 by Tommaso Zanzotto, Vice President of American Express Travel Division for Europe, Middle East and Africa.     

Network design for reverse logistics

Collection and recycling of product returns is gaining interest in business and research worldwide. Growing green concerns and advancement of green supply chain management (GrSCM) concepts and practices make it all the more relevant. Inputs from literature and informal interviews with 84 stakeholders are used to develop a conceptual model for simultaneous location–allocation of facilities for a cost effective and efficient reverse logistics (RL) network. We cover costs and operations across a wide domain and our proposed RL network consists of collection centers and two types of rework facilities set up by original equipment manufacturers (OEMs) or their consortia for a few categories of product returns under various strategic, operational and customer service constraints in the Indian context.     

A model for reverse logistics entry by third-party providers

Reverse logistics has become an important entity in the US economy. Nonetheless, many companies are not capable of or are unwilling to enter the reverse logistics market. Such reluctance appears to be attributed to lack of knowledge of reverse logistics. This paper reviews current industry practices in reverse logistics. Specifically, we examine the issues and processes that an organization has to address to engage in the reverse logistics business. A reverse logistics decision-making model is developed to guide the process of examining the feasibility of implementing reverse logistics in third-party providers such as transportation companies. The purpose of this model is to help those companies who would like to pursue reverse logistics as a new market. A field study was conducted with a larger US transportation company to validate the proposed model.     

Insolvency Proceedings and Workers’Rights: the Italian Case

ABSTRACT: In this paper the author analyses different types of insolvency proceedings in the context of the Italian legal system, focusing on the possible effects of bankruptcy law on employment relationships. The concept of‘privileged workers’claims is discussed, taking into account their rank of preference as stated by statutory law and according to the interpretations offered by jurisprudence. One section is expressly devoted to the recent legislation providing a Guarantee Fund for severance allowance claims in case of insolvency, but also in the event of mere nonpayment by the employer. After having covered the concept of 'super-privileged claims', the paper discusses more widely possible forms of protecting workers in a situation of company crisis and links between social legislation on the one hand, and bankruptcy law on the other. Finally, the author emphasizes the more effective protection now offered by the Italian legal system to workers’claims, although the trade unions have considerable difficulty in keeping the workforce united when insolvency proceedings are opened.     

A subsidized reverse supply chain in the Chinese electronics industry

We study a special environmental producer responsibility policy for the Chinese electronics industry that is based on awarding a per unit subsidy to qualified returned electronic products and ensuring a minimum producer collection volume while allowing larger collection volumes. Based on a real application from a Chinese electronics company that produces LCD TVs, our paper studies the optimal design of the product’s reverse supply chain when there is flexibility in settling the inspection locations of the returned products and flexibility in the volume of returned products collected. The problem is modeled as a nonlinear mixed-integer program and an efficient outer approximation-based solution approach is proposed. Analytical results and extensive numerical experiments based on this real application are conducted. Observations novel to the reverse logistics literature are related to the testing location decisions (upstream or downstream) and the optimal collection volumes of returned products. Particularly, we show how the government can stimulate the collection amount of returned products by increasing the unit subsidy and we also find that the company’s marginal benefit from improving the subsidy increases in a superlinear fashion. Furthermore, the highest collection volumes may not occur at the highest quality level of returned products for capacitated remanufacturers. The company can also be incentivized to increase the collection of returned products by permitting flexible testing locations. We also observe how the optimal testing locations vary for different levels of unit subsidy and different ratios of qualified and non-qualified returned products. Finally, conclusions and future research directions are provided.     

Supplier code of conduct–state-of-the-art and customisation in the electronics industry

In the field of corporate social responsibility (CSR), one efficient way to improve the ethical behaviour of a company is the implementation of a code of conduct. When focused on suppliers, this code is referred to as the supplier code of conduct (SCoC). Specific, application-oriented research on SCoCs is rare. The main goals of the present article are to define the state-of-the-art in SCoCs and to show how this review can be used in industrial practice when defining a company-specific SCoC. This article uses the electronics industry as an example. The state-of-the-art review of the content of the SCoCs is structured in five main categories of issues: labour standards, health and safety, environment, ethics and compliance. The practical relevance of this review is demonstrated by applying it in the development of a customised SCoC for a company as a part of the company's corporate risk management activities. This review uses the content analysis of SCoCs based on the website disclosures of the Forbes Fortune 2000 (Technology Hardware & Equipment) companies; which yielded 24 SCoCs. The application was done in an action research framework with a partner company, and the results were verified with the help of a focus group consisting of 10 companies.     

增加价值分配结构现状及其决定因素分析——基于我国上市公司的实证研究

文章以教育部博士点基金项目(2011年)为依托,将企业增加价值在其主要利益相关者之间分配份额(分配结构)作为研究对象,构建了非竞争市场因素影响增加价值分配结构结的结构方程模型框架,并以2003-2010年上市公司微观数据为样本,运用结构方程分析方法对相关假设进行实证检验。实证结果表明:1、目前国企相对民企、欠发达地区相对于发达地区以及商业相对于工业和地产对增加员工所得份额、降低政府所得份额有显著影响,表现为对分配结构存在显著的负向影响;2、股权集中度与经营绩效对增加员工所得份额、降低政府所得份额有影响,表现为对分配结构有正向影响,但统计上不显著;3、研究发现政府所得率与员工所得率之间呈反向变动关系。结论表明:非竞争市场因素对我国增加价值分配结构存在重要影响,在解决分配结构问题的时候,应尽量消除非竞争市场因素的不利影响。     

外部治理环境、内部治理结构与合谋侵占实证分析

本文以中国A股上市公司2003-2005年期间的数据为样本,实证分析了公司内部治理结构和外部治理环境对控股股东与管理者合谋侵占公司利益的行为产生的影响。研究结果表明:控股股东的持股比例与其对上市公司的资金占用正相关,而非控股大股东的持股比例与控股大股东对上市公司的资金占用负相关;集团控股股东对上市公司的资金占用程度显著高于非集团控股股东;董事会中内部董事的比例与控股大股东的资金占用正相关;地区法治化水平和政府干预程度这两个外部治理环境因素也对控股股东的行为产生了显著影响,地区法治化水平越高,政府干预程度越低,控股股东占用上市公司的资金越少。     

Issues in end-of-life product recovery and reverse logistics

There is a fundamental shift in waste management responsibility from the private waste management industry and local governments towards manufacturers, distributors, and retailers. In recent years the responsibility of manufacturers has been extended to cover the entire life of certain products. This also includes responsibility for the products safe disposal. As the enforcement of environmental legislation becomes more stringent and an increasing number of customers are demanding take-back of their old products, companies are beginning to focus on possible distribution channels for the return of their products i.e. reverse logistics. The aim of this paper is to examine the emerging issues in reverse logistics, in particular the information requirements for reverse logistics within the Extended Enterprise. A study of end-of-life vehicles (ELVs) will illustrate the specific information flow between the key players within the automotive industry. This paper addresses the initial development of possible distribution channels, their key operational decisions and supporting information systems for the recycling of end of life products.     

Developing a manpower strategy for an industry

This paper considers the following issues for developing an industry manpower strategy. An idea of the national system that exists for implementing a manpower strategy. The main questions arising from the strategy, and a definition of manpower planning. From this, the information and analysis techniques used to identify the strategy. The first application produces a manpower picture of the foundry industry. For company manpower planning the paper describes a manpower model of a company, and how the relationship between the activity and employment patterns of boundries was investigated. The industry findings are verified by company manpower planning investigations using the same information and techniques. The conclusions discuss some of the strengths and weaknesses of using this approach.     

Changing bonuses and the resulting effects of employees’ incentives to an inspection game

The following paper analyses an intraorganizational conflict in materials management between a manager, a controller and the company management. By using a game theoretic approach, this paper especially seeks to answer the question: ‘Do bonuses change employees’ incentives when the focus is directed at the control level of company management?’ This analysis is based upon an application of a three-person inspection game. Within the three-person game a partial influence of a variation of penalties and bonuses is measured analytically. A simultaneous variation of the bonuses for the subordinated players, as the incentive effect to guarantee rational behaviour, is presented here as a simulation. While different intervals of bonus values, which also affect the payoff of the company management, and their influence on the equilibrium probabilities are examined, it becomes apparent that bonuses are able to neutralize each other in their effect on improved decision-making behaviours of the manager (inspectee) and the controller (inspector). But also a diverse variation leads to positive and negative effects on the manager’s behaviour.     

对公司影像的勾画

本文认为,经济学家有必要更加多层次和全方位地勾画企业的图景。为此,从三维角度观察企业管理而形成的影像,构成了本文“理想化的维度”。这些维度分别是公司的利润、社会需求以及社会责任。一家企业类似一幅画,是企业家个人创造力与管理艺术的体现。它拥有自身的形式与结构,而且旨在体现和满足社会需求。在以三维角度对企业前景分析中,利润、社会需求以及企业和企业家社会责任等维度,应是企业管理理念与实践的主要维度。由于管理不同,企业性质和体制的色彩极其丰富。随着企业社会责任的不断增加,企业活动图景的维度也在不断扩展。     

跨国公司子公司自主性活动研究——从有限理性角度的分析

在跨国公司(MNCs)子公司演进模型中,子公司有着明显的自主愿望,自主权可以超越母公司的控制,引起对闲置资源的很大兴趣,激发子公司的积极性和创造性,但母公司也常常担心子公司的自主行为带有投机性,有可能偏离母公司的资源配置目标,使得MNCs迷失方向。而本论文认为母公司的有限理性是管理子公司自主性活动的主要交易成本,而非子公司的机会主义,母公司除了利用传统的克服机会主义的控制和协调工具之外,还应当重视使用内部市场机制和社会化方法,来减轻母公司的有限理性约束,形成母子公司间共同的认知地图,达成有意义的双方互利的联盟,从日益增多的子公司自主性活动中受益。     

Interface,Inc.: Taking the lead toward sustainability

Four years ago, CEO Ray Anderson of Interface began to confront his company's impact on the environment. The factories and suppliers of his interior furnishings company used 1.2 billion pounds of raw materials to produce $802 million in products. Of these materials, two thirds were exhaustible fuels. Anderson has set Interface on a mission—to became a sustainable enterprise. However, rather than dictating specific initiatives from the top down, his corporate strategy has been to use a seven-point program to provide guidance for each plant and business to create its own agenda. CES continues its exploration of what defines environmental leadership by exploring how Anderson has implemented this new type of corporate direction, and how Interface measures its progress towards this ambitious mission.     

Exploring the Importance of Business Clockspeed as a Moderator for Determinants of Supplier Network Performance*

As the importance of supplier networks becomes increasingly recognized as a vital factor to company performance, researchers and practitioners alike are focusing their attention on this subject. The study's main objective is to test the specific hypotheses that effective use of Information Technology (IT) and the depth of company relationships with suppliers are directly related to Supplier Network (SN) performance, and that industry clockspeed moderates these relationships. A convenience sample of 135 manufacturing organizations was used to empirically test these hypotheses. Our results indicate that clockspeed does moderate the relationship between IT use effectiveness and supplier network performance. The same is true in the case of supplier relations depth, and hence, managers are encouraged to pay attention to the items comprising network performance as a determinant of supplier network performance.
