基于获取决策优先权的零售商战略联盟效益分析

对于由一个供应商和多个零售商组成的单一产品、单周期供应链,在确定型市场、零售商成本对称以及供应商具有关于零售商成本结构完全信息的情况下,考虑了同时带来运作成本与决策权分配变化(基于获取决策优先权)的零售商定货数量决策联盟。利用博弈论方法,研究了获取决策优先权的零售商战略联盟对参与联盟的零售商、未参与联盟的零售商、供应商以及供应链整体收益的影响。证明这种零售商战略联盟不可能使供应链中所有成员都同时增加收益。但在一定的条件下,联盟能实现某种部分"多赢";使供应链整体、供应商和参与联盟的零售商收益增加,或使供应商和参与联盟的零售商收益增加。     

Adding life cycles to learning curves

The price-oriented experience curve has been extensively utilized as a model in corporate planning. However, managers exercise a greater degree of control over cost than they do over price. The use of the cost-oriented learning curve together with the product life cycle model in strategic planning is explored in this paper. The Ford Motor Company's experience with the Model-T, which was the first mass-produced automobile in the U.S., is used to reinforce the fact that the simultaneous use of the product life cycle and the learning curve would have provided Ford management with better planning information. With this information, Ford could have avoided the subsequent disastrous results which it experienced.     

Business planning in successful small firms

Strategic planning has been widely publicized during the last decade, but what has been accomplished by this management activity in smaller, high-growth firms? Business plans have been widely recommended for start-up funding, but we have noted additional uses for business plans in pratice. This article reports methods and results of strategic planning and written business plans in high-growth ‘INC. 500’ firms. In spite of a variety of obstacles, over half of the firms conduct strategic planning on a regular basis. Results of this study show that fast-growth firms develop written business plans as a product of strategic planning, mainly by five key management personnel. Written business plans are used more for internal management purposes than for start-up funding. Finally, the completion of strategic planning is positively associated with a firm's profitability. Based on survey and interview data, this article describes a four-phase model to help ensure effective integration of strategic planning processes and the resulting written business plans.     

考虑损失规避零售商的多期多产品供应链网络均衡

供应链是一个具有层级结构的复杂网络,一般包括制造商层、零售商层和需求市场层等渠道成员。为描述供应链网络的动态特征,本文将决策时间离散划分为多个规划期,同一规划期内各类成员的决策环境相对稳定;相反在不同规划期之间可能发生改变。制造商生产多种类型的产品,零售商面临随机需求环境且为损失规避者。运用前景理论描述了零售商的损失规避行为,利用制造商的库存转移来描述相邻规划期间的关系。利用变分不等式、对偶理论和互补理论刻画了制造商层、零售商层和需求市场层的最优决策行为,并推导整个供应链网络的均衡条件。设计了求解模型的修正投影算法。通过算例阐明了零售商盈亏平衡点的特征,分析了损失规避系数对供应链网络企业最优决策的影响。研究表明:随着损失规避系数的增大,零售商的第1盈亏平衡点减小,第2盈亏平衡点增大;零售商的订货量减小,其期望利润和期望效用增加,相反制造商和消费者的利益均受损;随着缺货成本的增加,零售商需向制造商订购更多的产品来规避缺货损失,但这也同时增加了其过量订货和滞销的风险;当零售商在某一期的损失规避系数发生改变时,零售商和制造商需在整个规划期范围内调整策略。     

Impact of Retailers with Knowledge of Supplier's Inventory on Supply Chain Performance

We model a supply chain consisting of a supplier and multiple retailers facing deterministic demand. We denote some retailers as strategic in the sense that given the supplier inventory information, they will implement the optimal stocking policy by incorporating such information. On the other hand, some retailers are denoted as naïve in the sense that they ignore supply information and resort to a simplistic ordering policy. Naïve retailers learn the optimal policy over time and adjust their orders accordingly. We study the dynamics of this game and investigate the impact of such strategic and naïve retailers on the cost, ordering pattern and stocking policies of all parties. We analyze the supply chain under two scenarios: the centralized supply chain where the objective is to minimize the total supply chain cost, and the decentralized supply chain where each self‐interested player minimizes its own cost in a Stackelberg game setting. We fully characterize the optimal policies under both centralized and decentralized scenarios and show that, surprisingly, the supply chain might be better off by virtue of naïve retailers. The result is driven by the fact that strategic and naïve players’ decisions shift the positioning of inventory in the supply chain with its final impact being determined by the relative costs of different retailer‐types. Our results also offer managerial insights into how access to supply information can improve supply chain performance.     

Strategy and Opportunism in European Retail Internationalization

Europe in recent years has witnessed an increase in the amount of cross‐border operations by retailers. The retail sector has undergone substantial structural change characterized by the emergence of a group of rapidly‐growing large retailers, a redefinition of the balance of internalized and externalized functions and a need to respond to the cultural variety present in Europe that becomes evident as retailers move out of their domestic markets. The over‐arching requirement for these large retailers is to grow and gain scale economies. Internationalization of operations has become a requirement for these large firms. It is argued that the established academic conceptualizations of internationalization are unsatisfactory in not addressing this overriding requirement for growth. There is great variety in the international activity in retailing, with the absence of pattern being one of the few generalities. It is proposed that consideration of opportunism may be a better way to gain understanding of retailer activity than trying to fit activity into deterministic strategic models. The experiences of five West European retailers entering and building retail networks in Poland is provided as evidence for this view. Suggestions are made for future work exploring this issue of opportunism as a process in international retailing.     

Comprehensive planning for libraries

In the area of planning, the literature has been almost entirely concerned with planning in the business (i.e. profit) setting. Some literature does exist on planning in the nonprofit sector, but it usually deals with tactical planning of the short-term character. This is specially true in the area of libraries and many librarians have developed and do administer large, complex organization— where conprehensive, long range planning is almost completely untreated in the literature.The current paper discusses the various steps in the strategic planning process, and relates them to a situation in which comprehensive long range plans for a new health sciences library have been developed, and to a considerable degree, implemented. In this framework, the steps of developing purpose and objecives, forecasting and policy formulation, developing and choosing growth strategy, determining resource requirements and provions, developing an organizational structure, and control system utilization are discussed both in the general framework of comprehensive planning, and with respect to actual experience in the development of a health sciences library. The roles of tactical planning and the implementation of plans are also treated.     

How planning and capital budgeting improve SME performance

This paper focuses on the use of strategic planning among small and medium sized enterprises (SMEs) in the UK manufacturing sector. It analyses the relationship between the intensity of strategic planning, business objectives, perceived performance, changes in the business environment and the use of capital budgeting techniques. Capital budgeting is of particular interest as an area of investigation, and is one which has seldom featured in previous studies of strategic planning behaviour. These issues were investigated via a survey of UK manufacturing SMEs carried out in the winter of 1996/97.

The key results suggest that SMEs incorporate a range of objectives into their strategic planning process, with profit improvement perceived to be the most important objective, followed by sales growth. SMEs engaged in detailed strategic planning are more likely to use formal capital budgeting techniques, including the net present value method, which is consistent with maximising the companys' value. Perceived profitability and success in achieving organisational objectives were positively associated with planning detail, suggesting that strategic planning is a key component improving performance. Planning detail was also associated with a significantly higher level of perceived change in the business environment.     

Shipping Fees or Shipping Free? A Tale of Two Price Partitioning Strategies in Online Retailing

In this article, we study the price partitioning decisions of online retailers regarding shipping and handling (S&H) fees. Specifically, we analyze two partitioning formats used by retailers in this context. In the first scenario, retailers present customers with a price that is partitioned into a product price and a separate S&H surcharge (the PS strategy); in the second, customers are offered free shipping through a non‐partitioned format where the product price already includes the shipping cost (the ZS strategy). We first develop a stylized game‐theoretic model that captures the competitive dynamics between (and within) these two formats. Analysis of the model provides insights into how both firm and product level characteristics drive a retailer's strategic choice regarding which partitioning format to adopt and, hence, determines the equilibrium market structure in terms of proportion of ZS and PS retailers. Subsequently, we conduct empirical analyses, based on product and S&H prices data for two different product categories (digital cameras and printers) collected from online retailers, to validate all the results of our theoretical model. We establish that PS retailers charge lower product prices than ZS ones, but the total price (product + S&H) charged is higher for the first group. The S&H charge for PS retailers can be significant—it is, on average, 5.4% (printers) and 3.0% (digital cameras) for our two product categories. Furthermore, retailers which are popular and/or face risky cost environment are more likely to opt for the ZS strategy, while retailers whose portfolio mostly includes large or heavy products with high cost (S&H)‐to‐price ratios usually choose the PS strategy. Lastly, our empirical study also illustrates that the price adjustment behavior of retailers is affected by their shipping‐fee policies—for example, ZS retailers change their product prices almost 1.5 times more frequently than PS ones.     

竞争环境下基于顾客策略行为的易逝品动态定价研究

在两个提供相同易逝品的零售商折线竞争下,从顾客策略行为出发,研究竞争环境下两零售商的动态定价策略。首先建立供大于求的情况下两零售商动态定价模型,给出了均衡价格满足的条件,并探讨了在一些特殊情况下均衡价格的特性。然后将这一模型扩展到供小于求的情形,探讨模型的求解方法。算例分析了在折线竞争模式下零售商在面对顾客策略行为时,如何动态的决定价格。同时发现,在供大于求的情况下,顾客策略行为导致零售商的收益降低;在供小于求的情况下,一定程度的顾客策略行为可以使零售商获得更高的期望收益。     

零售商嵌入专业技术的营销策略研究

考虑零售商和技术提供商的二元结构,本文构建理论模型分析零售商嵌入专业技术的营销策略选择问题,并探讨技术嵌入以及技术营销策略对决策结果的影响。研究发现,技术提供商作为博弈的领导者在获取边际利润方面具有优势且相对稳定;并且对技术提供商而言,让零售商进行技术营销的策略是最优的。然而,对于零售商而言,不同技术营销渠道下的利润大小会受到技术产出、技术营销、以及营销努力博弈的影响,因此零售商的策略选择较为复杂。在一定的条件下,零售商可以嵌入产出贡献度较大的专业技术,并优先选择自己进行技术营销以增加技术营销贡献度。这一策略有利于零售商快速实现利润最大化,并与技术提供商实现双赢。     

Scenarios, past, present and future.

A key point in considering strategic planning is that it is not forecasting. The future is unpredictable and is not a product of the past. This low opinion of forecasting has gained in influence recently. But such an approach creates a dilemma for the strategic planner. He needs to take into account potential future forces--but he can only do this with inadequate means. Forecasting methods, however, can suggest trends and it is possible to reduce the number of possible futures to a manageable number. This is, in effect, creating scenarios. The concept of using alternative scenarios in planning was popularized some 20 years back. The proviso was made that they should not be interpreted as forecasts. The methods have proved highly flexible and include the consensus technique, the iteration-through-synopsis technique, and the cross-impact method. Various studies using one or more of these have been implemented, perhaps the best known being by Meadows and by Mesarovic. These have been based on the so-called 'hard' method, using computers. 'Soft' methods are based more on the mind and use psychology and sociology, the most familiar being the Delphi method. A somewhat more sophisticated version is Cross-Impact Analysis.     

Strategic planning in large firms—some guidelines

Some argue that a foundation for planning has been achieved when a firm can state its strategic plan in terms of products and markets. (This is referred to as the ‘business form’ in this article). If this statement is true, what factors will aid a firm in achieving the business form in its strategic plans? In this article, details of strategic planning in over 50 large firms taken from an empirical research sample are examined to illustrate which factors seem to lead to the business form of strategic plan in these firms.     

Strategic management: lessons from success and failure.

Is Corporate Planning a failure or a success? In this article David Hussey assesses the research which has been done on the planning process and concludes that Corporate Planning obviously has the potential to improve business performance but for many reasons this potential has not been realized. He then examines the attempts which are currently being made to persuade managers to ‘think strategically’, to use portfolio analysis scenarios and other techniques of strategic analysis. He asserts that to succeed, the planner or the consultant in planning must use these and other analytical approaches to help managers ‘to change the perceptual boundaries of the strategic problem’ and generate strategies and action programmes which will enable them to compete successfully in world markets.     

Strategic planning in small and medium-sized companies

In analysing the characteristics of strategic planning applications in different types and sizes of companies, confusion often arises not because of the application but because of the definitions utilized. This paper analyses the use of strategic planning concepts in small and medium-sized companies in Holland. As the author points out, in this context the definition of small and medium-sized is determined by five strategically relevant criteria which are distinctive. The author points out, however, that whilst these criteria are distinctive of the category of small and medium-sized companies surveyed, they do not all have to occur at the same time; the higher the number that do occur, the more typical the company. Whilst this paper does not, as the author admits, represent the result of a systematic survey, the authors wide experience as a consultant is in itself a valuable background to his analysis. Indeed, the findings stated in this paper represent an analysis of the strategic planning practises of some 75–100 companies. Therefore, in view of the detailed criteria utilized and the number of companies analysed the results represent an important addition to our knowledge of the application of strategic planning.     

How to integrate strategic planning into your management process

The primary purpose of strategic planning is to enable management to make decisions today which will affect the firm over the long run where the long run is characterized by risk and uncertainty. If strategic planning is to be useful to management it must be an integral part of the decision making process and not merely an appendage to the management process. In this paper we shall define some of the problems involved in integrating strategic planning and strategic planning tools into the decision process. We shall also suggest some possible solutions to these problems.     

Understanding managers' preferences for internal markets versus business planning: A comparative study of German and U.S. managers

Internal markets and centralized business planning are alternative organizational designs for coordinating the economic activities within a firm. While some preliminary theory about when to use each exists in the literature, little is known about how managers understand and decide when to use one or the other. The study develops and tests in samples of German and U.S. managers a preliminary theory about factors that influence the preferences of managers for internal markets or planning as alternative modes of coordination. Managers' preferences are influenced by key constructs of internal markets and planning theory (the perceived limits of planning, speed and efficiency of markets, motivation potential of markets), but also by differences in their institutional contexts (national government and business context, company culture, and recent company experience with planning and internal markets). The study is the first to explore the substitutability of internal markets and planning within the strategic decision process of managers, closer to where it becomes reality.     

Managing stochastic demand in an Inventory Routing Problem with transportation procurement

We study an Inventory Routing Problem in which the supplier has a limited production capacity and the stochastic demand of the retailers is satisfied with procurement of transportation services. The aim is to minimize the total expected cost over a planning horizon, given by the sum of the inventory cost at the supplier, the inventory cost at the retailers, the penalty cost for stock-out at the retailers and the transportation cost. First, we show that a policy based just on the average demand can have a total expected cost infinitely worse than the one obtained by taking into account the overall probability distribution of the demand in the decision process. Therefore, we introduce a stochastic dynamic programming formulation of the problem that allows us to find an optimal policy in small size instances. Finally, we design and implement a matheuristic approach, integrating a rollout algorithm and an optimal solution of mixed-integer linear programming models, which is able to solve realistic size problem instances. Computational results allow us to provide managerial insights concerning the management of stochastic demand.     

The state of private sector strategic planning in Canada

This paper examines Canadian strategic planning expertise from a number of different aspects. It evaluates the relative sophistication of Canadian and American management consultants and points out that the U.S. expertise is still particularly good and preferred. It is perhaps a pertinent comment that the view of many is that ‘The U.S. people have … defined their products in such a way as clients can use them’. Analysis of the stimuli for strategic planning is an appropriate focus, particularly since it concludes that it is rare that a visionary cheif executive is responsible! Most companies appear to pursue strategic planning through fear rather than enlightenment. The quality of input to the planning process varies widely, with extrapolation from the past a major preoccupation. There appears to be a lack of environmental analysis. The author analyses a number of important issues and concludes that a bolder embrace of strategic planning would serve Canadian management well in responding to the extensive challenge facing their country's economy in the next 10 years.     

Developing a company's strategic management capability

Companies vary widely in their strategic management capabilities. Some still rely almost entirely on ‘fire-fighting’. Many others are slowly developing their capabilities but there are only a few which do give due attention to strategic issues and implement their decisions effectively. To be effective a corporate planner must assist this process of development of strategic ability and must adapt his role as the company's capability changes. In the most successful corporate planning units it is clear that this change in role is occuring, but is there not also a largely untapped market for consultants to assist companies in developing these capabilities?
