智联产品服务供应链研发运维多阶段联合优化与协调

在智联化和服务化背景下,智能产品服务系统成为制造企业转型升级的重要方向。产品的“智能”和“互联”特性给供应链中的产品和服务都带来了新的变化。考虑产品的“智能”和“互联”对产品、服务的需求和成本的影响,构建了供应链两阶段动态博弈模型。刻画了分散决策和集中决策下供应链的最优运作行为,基于产品收益和服务收益提出了“双元收益共享”的供应链协调机制。通过算例分析,探讨了“服务化”、“智能互联”与“双元收益共享”契约对供应链利润的影响。研究表明,智联产品供应链中融入智能服务,不总是能增加供应链利润,存在“服务化悖论”;当产品智联化后,智能互联特性加强了产品与服务的融合,使供应链各方的利润都有较大提高;“双元收益共享”契约不仅能实现供应链Pareto改进,还能提高消费者剩余。     

零售商主导下促进绿色产品需求的联合研发契约协调研究

针对绿色环保产品价格过高,阻碍其成为主流消费品这一现实问题,在绿色经济背景下,探讨零售商向负责绿色研发成本投入的制造商提供不同联合研发契约时的供应链均衡策略和协调问题。以零售商主导的双边垄断型绿色供应链为研究对象,在考虑消费者环保意识、产品绿色度水平、价格等多种因素影响需求的基础上,分别探讨批发价契约、成本分担契约和两部制契约对绿色产品需求、供应链成员利润及渠道利润的影响。结果表明,成本分担契约无法实现供应链成员利润的Pareta改进;一定条件下,两部制契约可以实现供应链成员利润的双赢,并提高绿色产品的市场需求。此外,虽然消费者环保意识的提高并不总是会带来绿色产品市场需求的增加,但却总是会使得绿色供应链的利润提高;并且较高的消费者环保意识将激励企业追求一个较低的绿色成本系数,从而促使企业积极进行绿色技术创新努力。     

Partners in new product development: SC Johnson and the alliance for environmental innovation

In the previous issue of CES (Winter 1999), SC Johnson's early efforts at integrating core business decisions with environmental concerns were explored by researchers at INFORM, Inc. By gaining upper management attention, explicitly aligning environmental concerns with key business goals, and designing consistency into the overall company management system, SC Johnson was able to “break down the green wall” in the organization.In this follow-up article, CES explores a recent effort between the Alliance for Environmental Innovation and SC Johnson to further integrate environmental decision making throughout the organization. The project focused on: (1) creating practical tools to identify environmental considerations at the earliest stages of new product development, and, (2) addressing consumers' environmental needs in the conception and marketing of “greener” products. The Alliance and SC Johnson formed a task force that included both staff members from the Alliance, as well as members of the environmental, product development, product safety and marketing staffs at SC Johnson. This unique partnership has aided SC Johnson by more directly linking consumer and company environmental objectives to the new product development process.     

Greening the electricity industry: The dynamic logic of the Green-e certification program

With the advent of retail completion in the supply of electricity to end-use customers, individuals and businesses will be given the opportunity to purchase electricity from “green power” sources. Some customers are clearly willing to pay a premium for environmentally preferable sources of electricity supply. Yet, there have been concerns that customer confusion, vague marketing claims, and “apples and oranges” comparisons will limit the potential market penetration of green power products.Environmental certification programs are increasingly seen as important tools for achieving environmental objectives and are intended to alleviate some of the concerns listed above, as well as to increased product and marketer credibility. The Green-e Renewable Electricity Branding Program is the first U.S.-based effort to certify green power products that meet certain environmental standards. The voluntary Green-e program also helps create consumer confidence in these certified products through a marketer code of conduct, disclosure provisions, and a public education campaign. This article details the development, design and results of the Green-e program to date.     

Sustainable Operations Management

Operations management researchers and practitioners face new challenges in integrating issues of sustainability with their traditional areas of interest. During the past 20 years, there has been growing pressure on businesses to pay more attention to the environmental and resource consequences of the products and services they offer and the processes they deploy. One symptom of this pressure is the movement towards triple bottom line reporting (3BL) concerning the relationship of profit, people, and the planet. The resulting challenges include integrating environmental, health, and safety concerns with green‐product design, lean and green operations, and closed‐loop supply chains. We review these and other “sustainability” themes covered in the first 50 issues of Production and Operations Management and conclude with some thoughts on future research challenges in sustainable operations management.     

Harnessing SD and CSR within Corporate Self‐regulation of Weak Economies— A Meta‐regulation Approach

The semantic of the terms “sustainable development” and “corporate social responsibility” have changed over time to a point where these concepts have become two interrelated processes for ensuring the far‐reaching development of society. Their convergence has given dimension to the environmental and corporate regulation mechanisms in strong economies. This article deals with the question of how the ethos of this convergence could be incorporated into the self‐regulation of businesses in weak economies where nonlegal drivers are either inadequate or inefficient. It proposes that the policies for this incorporation should be based on the precepts of meta‐regulation that have the potential to hold force majeure, economic incentives, and assistance‐related strategies to reach an objective from the perspective of weak economies.     

MANAGING CYCLIC INVENTORIES

Cyclic inventory is the buffer following a machine that cycles over a set of products, each of which is subsequently consumed in a continuous manner. Scheduling such a machine is interesting when the changeover times from one product to another are non‐trivial—which is generally the case. This problem has a substantial literature, but the common practices of “lot‐splitting” and “maximization of utilization” suggest that many practitioners still do not fully understand the principles of cyclic inventory. This paper is a tutorial that demonstrates those principles. We show that cyclic inventory is directly proportional to cycle length, which in turn is directly proportional to total changeover time, and inversely proportional to machine utilization. We demonstrate the virtue of “maximum changeover policies” in minimizing cyclic inventory—and the difficulty in making the transition to an increased level of demand. In so doing, we explicate the different roles of cyclic inventory, transitional inventory, and safety stock. We demonstrate the interdependence of the products in the cycle—the lot‐size for one product cannot be set independently of the remaining products. We also give necessary conditions for consideration of improper schedules (i.e., where a product can appear more than once in the cycle), and demonstrate that both lot‐splitting and maximization of utilization are devastatingly counter‐productive when changeover time is non‐trivial.     

考虑顾客效用和时变品质度的乳品供应链品质激励契约研究

考虑时间因素对乳制品品质的影响,构建“时变品质度”函数,结合消费者效用的敏感性,将乳品品质加成和时变特性与厂商收益管理有机结合,设计“批发价+收益共享”契约和“收益共享+品质投入成本共担”契约作为激励机制,来促进乳制品供应链上的主体企业提高品质投入水平。研究结果表明：单纯的“批发价+收益共享”契约对加工企业品质投入的激励效果有限,而“收益共享+品质投入成本共担”契约可以实现供销双方经济利润的帕累托改进,明晰供销双方在品质投入问题上的利益分配与权责关系,并在一定参数取值区间内,协调实现整体供应链利润最优。最后通过数值算例进行参数敏感性分析并验证相关结论。     

不确定需求下考虑资金约束的生鲜农产品政府补贴策略

针对需求不确定环境下政府如何对生鲜农产品供应链进行补贴的问题,在考虑财政资金的约束下,分别构建了无政府补贴、采购补贴和销售补贴三种情形下的博弈模型。通过对比分析得出了政府的最优补贴策略,并分析了补贴策略对生鲜供应链最优决策的影响,最后用数值算例进一步说明了不同补贴策略对不同类型生鲜农产品的影响。研究发现,补贴策略的选择与财政预算密切相关。在财政预算充裕时,两种补贴策略都有效且可行,都能平抑物价、增加供给、拉动需求;从改善社会整体福利的角度,采购补贴为最优策略;从补贴资金效率的角度,销售补贴为最优策略。在销售补贴预算充裕而采购补贴预算存在缺口时,销售补贴为最优策略。在财政预算不足时,政府的最优策略就是不干涉市场的运营。     

Eco-efficiency and Integrated Product Policy: Lessons from Finland

Eco-efficiency refers to the use of our natural resources — economically, socially and ecologically — in the most efficient manner possible, while containing environmental damage. The main aim is to improve the ratio service produced by the product to harmful environmental impacts. Together with Integrated Product Policy (IPP) it shifts environmental protection from the reduction of production phase emissions and waste towards environmental impacts of products’ whole life cycle, effective use of natural resources and market orientation. IPP is more clearly an environmental policy strategy and program, where the role of the government and of various policy instruments is inevitably underlined. Finnish Environmental policy exemplifies how these new concepts have already been taken into account in strategies of sustainable development and why it is important not to apply them separately, but to find the means by which eco-efficiency thinking and the factor goals it includes can be considered when IPP is being developed.     

Startups internationalizing in quest of a business model: The global prospecting of process niche firms

This paper examines technology startups whose initial offering is not a tangible product or service, but rather a technology used in the production process of goods and services of other firms. These “process niche firms,” as we call them, represent an emerging and increasingly common feature of the digitized economy. As part of their search for a suitable business model – be it products, services, and/or outright licensing of intellectual property – process niche firms engage in early internationalization in order to gain relevant market knowledge and identify possible business partners. A framework is derived to examine the internationalization pattern of such firms. The paper draws on four illustrative case studies providing insight into how such process niche firms “prospect” in foreign markets prior to deciding on the business model that suits them best. Early in their life cycle, process niche firms may decide to locate their headquarters in a different country in closer proximity to relevant markets and partners, as their high knowledge intensity and dearth of tangible assets makes them highly movable. Later in their development, process niche firms will likely evolve into other types of firms, depending on the business model they ultimately choose and the process that they follow.     

The Global Food Industry and “Creative Capitalism”: The Partners in Food Solutions Sustainable Business Model

Rising global food prices have driven 44 million additional people into extreme poverty—and malnutrition—in developing countries since June 2010. Partners in Food Solutions (PFS), a nonprofit social enterprise affiliated with General Mills, is proposed as the conduit for food industry managers, engineers, and scientists to initially advise small‐ and medium‐sized African mills and food processors—and later other developing countries—on improving supply chain management by addressing manufacturing problems, developing products, improving packaging, extending product shelf, and finding new product markets. In this article, the “creative capitalism” model of sustainability and social and environmental responsibility is applied to the food manufacturing industry's efforts supporting PFS. Furthermore, the evolution of the sustainable business model developed by PFS is thoroughly described, explained, and analyzed as a generic model of social enterprise to be “scaled up” by the global food manufacturing industry. A summary of salient points conclude the article.     

Breaking down the “Green Wall” (part one): Early efforts at integrating business and environment at SC Johnson

Integrating environmental management initiatives with business functions, such as manufacturing and purchasing, is now a major goal in many firms. Most environmental professionals agree that success in this pursuit is a product of their greater involvement with traditional business management areas as well as their ability to avoid the “green wall”—the separation between environmental and business functions that companies often experience.In this article, the first of a two-part series, Mark Haveman and Mark Dorfman examine how some firms deliberately break down these barriers. The case study of SC Johnson specifically illustrates how elements such as gaining senior management commitment, explicitly aligning environmental issues with key business goals, and designing consistency into the overriding management system can all lead to breaking down that integration. In the next issue, authors from SC Johnson and the Alliance for Environmental Innovation will discuss a recent project to further the efforts of business-environment integration.     

Key survival issues: Practical steps toward corporate environmental sustainability

Environmental pressures and growing societal commitment to the ideal of “sustainable development” pose profound strategic challenges for business. Recognition of the significance of sustainable development for business and eagerness to “do something” has lead to a number of responses from companies. The most effective corporate response is to build an environmentally sustainable business. The Environment Council through its work had developed an elegantly simple and proven approach to producing and implementing a strategy for doing this.This approach involves recognising that corporate strategic environmental opportunities and threats fall into three inter-related categories; Resources, Innovation, and Values. Applying the simple technique of a Strenghts, Weaknesses. Opportunities and Threats (SWOT) analysis of the business against these fields enables managers to establish the organisation's environmentally-driven key survival issues (KSIs) - environmental threats and opportunities to which the company has to develop the right response to ensure survival and prosperity. Every business has perhaps two or three key survival issues, though few seems to know what they are and even fewer are doing anything serious about them. The article gives some guidance on identifying key survival issues and how to develop a consistent corporate response.

Charisma,Macht und Narzissmus

Charisma, power and narcissism. On the diagnostics of an ambivalent leading qualityManagers are often obviously narcissistic personalities with “charismatic qualities”. The author discusses the background of these qualities and their ambivalence, because behind the brilliance of a successful manager may be a hidden narcissistic problem as the actual motive power. Nevertheless a constructive narcissism is to be distinguished from a destructive one. Charismatic constellations as well as narcissistic dynamics are to be understood not only as an individual problem but as an interactional phenomenon, involving both sides of a relationship. In order to explain these dynamics, the author presents the concepts of “narcissistic collusion” and “expanded self”. It is of great importance to the coach, to be able to analyse and to deal with these relational patterns — and also to preserve oneself from being involved in such narcissistic dynamics.     

An Anticipatory Governance Approach to Carbon Nanotubes

Carbon nanotubes (CNTs) are novel materials with remarkable properties; possible beneficial applications include aircraft frames, hydrogen storage, environmental sensors, electrical transmission, and many more. At the same time, precise characterization of their potential toxicity remains elusive, in part because engineered nanostructures pose challenges to existing assays, predictive models, and dosimetry. While these obstacles are surmountable, their presence suggests that scientific uncertainty regarding the hazards of CNTs is likely to persist. Traditional U.S. policy approaches implicitly pose the question: “What level of evidence is necessary and sufficient to justify regulatory action?” In the case of CNTs, such a strategy of risk analysis is of limited immediate utility to both regulators essaying to carry out their mandates, and users of CNTs seeking to provide an appropriate level of protection to employees, customers, and other stakeholders. In contrast, the concept of anticipatory governance suggests an alternative research focus, that is: “Given the conflicted character of the data, how should relevant actors respond?” Adopting the latter theoretical framework, this article argues that currently available data support treating CNTs “as if” they are hazardous, while simultaneously highlighting some systemic uncertainties in many of the experiments carried out to date. Such a conclusion implies limiting exposure throughout product lifecycles, and also points to the possible applicability of various conceptual tools, such as life‐cycle and multicriteria decision analysis approaches, in choosing appropriate courses of action in the face of prolonged uncertainty.     

Five years of the CES Journal and strategic environmental management: Quantum leaps,one step at a time

Just as the Corporate Environmental Strategy Journal has changed greatly in recenty years, so too has the field of Strategic Environmental Management. From struggles with pollution prevention to finding the path towards sustainable development, Steven Rice reflects upon the evolution of this field by looking at the history of the CES Journal. The publication offers a lens to better analyze the past and imagine the possibilities and predictions for the future.The author sees the field for Strategic Environmental Management continuing to move beyond mere compliance strategies and towards total integration into organizations, through matured organizational learning. This includes the maturation of environmetal management systems, a focus on environmentally-related new product development and marketing, and ultimately, the acceptance of environmental strategy as a part of the whole business strategy.
