基于战略的流程选择层次分析法研究 总被引:4,自引:0,他引:4
企业流程再造(BPR)是企业战略层次的管理革命。正确地选择对战略目标起最大作用的重组流程是流程再造取得成功的基础,目前的BPR研究多把重点放在再造对流程绩效的影响,缺乏再造流程选择的科学方法。基于战略的观点,用层次分析法审视流程的再造优先级,实例表明此方法能有效指导流程再造。 相似文献

首先分析了企业的品牌价值与其销售额的变化情况,归纳出品牌价值与销售额之间的两个重要的变化规律.而后以此作为二者关系方程构建的基础假设,以广告反映模型(VW模型)为基础,将原模型中的广告投入变量替换为品牌价值变量,建立了品牌价值与销售额之间的关系方程.通过求解关系方程的平衡解,得到了以品牌价值为变量的销售额预测模型.最后,采用海尔集团的实际数据对所建模型的适用性和正确性进行了证明,同时还对模型的预测精度进行了检验.研究突破了以往研究一般采用时间、环境变量直接预测销售额,或是采用历史数据对销售额进行模拟预测等传统的预测方法,首次从品牌价值的角度出发研究其对销售额的影响途径及影响力度.品牌价值是能够包涵如广告投入等因素的全部信息量的重要指标,因此其能够更为全面客观地衡量商品在整个市场中的价值潜力、能够更准确地反映其未来的销售份额. 相似文献

针对DEA交叉效率评价过程中没有考虑自评与互评效率的作用而主观赋予相同权重导致交叉效率评价值不准确的问题.文章基于参数设计的思想,依据试验设计中可控与不可控因素的作用机理区分自评权重和互评权重对所评价决策单元交叉效率的影响与作用,将其界定为可控与不可控因素的管理学属性,明确不同权重作用机理;引入信噪比作为衡量决策单元交叉效率评价时的性能指标,实施DEA交叉效率评价方法的改进,设计出DEA信噪比交叉效率集结方法,从而实现交叉效率的集结方式由单一考虑交叉效率波动的均值转化为综合考虑交叉效率波动情况(均值与方差),交叉效率评价值用信噪比交叉效率替代交叉效率平均值更具有统计学意义并可从管理学角度解释,评价结果也具有更高的可区分性;最后通过算例分析验证了交叉效率评价理论上的必要性和该方法的合理性与可行性,同时发现了交叉效率评价中存在CCR有效DMU序位超出了有效DMU范围现象,建议应实施同质DMU检验和评价值归一化.文章的研究也为提高DEA交叉效率测算的准确性提供一种新思路. 相似文献

Despite undoubtedly being one of the latest fads, Business Process Reengineering (BPR) has provoked much debate about how organisations should be managed if dramatic improvements in performance are to be achieved. This paper takes a multidisciplinary view of BPR and focuses upon a number of the emergent issues. These include the role of strategy making, the promotion of communication and creativity, the role of statistics, and the effective use of performance measurement systems within a learning environment. The paper develops a framework that capitalises on the role of modelling in MS/OR as well as the various disciplines of the authors. As such, the framework draws on recent advances, as well as established thinking, in the areas of strategy development, information systems, quality management and statistical science. More importantly, the framework also provides an iterative approach to BPR enabling organisations to design, implement and monitor progress on an ongoing basis. Emphasis is placed on building effective communications, developing an organisational memory and supporting organisational learning. 相似文献

Analytical sales force compensation research offers only limited answers to sales managers who try to devise effective compensation plans, because it often rests on restrictive assumptions, and it considers only simple compensation plan structures. In practice, sales managers need to predict how alternative and relatively complex compensation schemes would affect sales revenues and profits, as well as their likely impacts on sales force morale and turnover. This is why they typically obtain key salespeople’s prior reactions to a new scheme, or pretest the new plan on a limited scale. These procedures, however, may not provide accurate long-run predictions, and they can be applied to only one or two schemes at a time. The paper proposes the application of a simple Markovian model for assessing the long-run impacts of alternative compensation plans on sales and profits, taking into account the associated benefits and/or costs of variations in sales force motivation and turnover. A simple application is provided and implementation issues are discussed. 相似文献

The stylized model presented is an optimal control model of technology investment decision of a single product firm. The firm’s
technology investment does not have only a long-run positive effect but also a short-run adverse effect on its sales volume.
We examine the case of high adverse investment effects where the firm finally leaves the market but we have observed different
life cycles till this happens. Depending on the firm’s initial technology stock and sales volume, we compute different firm’s
life cycles, which are driven by a trade-off between two strategies: technology versus sales focus strategy. Indifference
curves, where managers are indifferent to apply initially technology or sales focus strategies, separate founding conditions
of the firm to various classes distinguishable because of the firm’s life cycle. 相似文献

An appropriate sales forecasting method is vital to the success of a business firm. The logistic model and the Gompertz model are usually adopted to forecast the growth trends and the potential market volume of innovative products. All of these models rely on statistics to explain the relationships between dependent and independent variables, and use crisp parameters. However, fuzzy relationships are more appropriate for describing the relationships between dependent and independent variables; these relationships require less data than traditional models to generate reasonable estimates of parameters. Therefore, we have combined fuzzy regression with the logistic and Gompertz models to develop a quadratic-interval Gompertz model and a quadratic-interval logistic model, and we applied the models to three cases. Our practical application of the two models shows that they are appropriate tools that can reveal the best and worst possible sales volume outcomes. 相似文献

优质农产品溯源系统的引入,既能提升有效供给、缩短流通时间,又能降低流通中的数量损耗和价值损失,由此带来了双渠道供应链系统在投资、销售、定价等方面的系列决策问题。考虑制造商开辟电子渠道、从溯源系统降低流通损耗和提高质量出发,分别构建制造商主导型的双渠道供应链决策模型。通过对比分析应用前后各成员在投资、定价及销售方面的最优策略,得到相关的核心边界值。数值仿真结果表明:核心边界值主要与双重损耗的改善程度及其他参数相关,各成员及系统接受溯源系统的应用成本不同,应用成本对各渠道销量的影响程度亦不相同,但各成员调整定价的应用成本边界值是一致的。 相似文献

Efficient workforce scheduling has an important impact on store profit and customer service. Standard scheduling problems do not recognize the effect of staff availability on customer sales, however, even though the latter is an important factor in the retail sector. In this paper a two-stage model is proposed for this purpose. In the first stage a sales response model is used to specify hourly staff requirements. The output of the sales response model is then used as the input of a mixed integer optimization model, which finds an optimum assignment of the staff to daily shifts. Simulations are used to validate the sales response function, and to revise the model for more accurate results. In the simulations, customer arrivals and sales response error values are generated using appropriate distribution functions. As a case study the proposed model is applied to a Turkish retailer in the apparel sector. 相似文献

A retailer needs to make decisions regarding how much to order and how much sales effort to exert in an environment with uncertain demand. One intrinsic complexity in a typical retail environment is caused by the fact that the retailer can obtain information about demand only based on sales, as demand itself is unobservable. Taking a Bayesian approach, Lariviere and Porteus (1999) show that in such a setting a retailer should stock more to increase the probability of an exact demand observation. In this article, we extend their work by allowing the retailer to control both the stocking quantity and sales effort, which can be used to affect demand. We show that their insights with respect to information stalking carry over to this setting. In addition, our model allows gaining a better understanding of optimal sales effort strategies. We find that demand management has a dual role in supporting information gathering: while at the beginning of a product life cycle it is optimal to support learning effects by sharply reducing sales effort, at later stages of the product life cycle an aggressive strategy of increased promotional activities can be used to harvest the information gathered in earlier periods. 相似文献

In this paper we show that the geodesic flow on a compact locally symmetric space of nonpositive curvature has a unique invariant
measure of maximal entropy. As an application to dynamics we show that closed geodesics are uniformly distributed with respect
to this measure. Furthermore, we prove that the volume entropy is minimized at a compact locally symmetric space of nonpositive
curvature among all conformally equivalent metrics with the same total volume. 相似文献

This paper describes the solution of the practical problems encountered by a Company when a product is made and sold for a limited promotional period only. The production and inventory control aspects are considered and a system aimed at the reduction of obsolescence costs is described which is based on a model of the demand pattern which uses a Gompertz exponential growth curve. Under pressure for an early improvement from the organisation, a system based on an empirical model was implemented, as an interim measure, which achieved a considerable improvement in performance. The Gompertz model has now been put into operation and the results of a simulation model are presented indicating that further improvements can be achieved. 相似文献
