This paper addresses a new problem in designing and planning a multi-echelon and multi-product supply chain network over a multi-period horizon in which customer zones have price-sensitive demands. Based on price-demand relationships, a generic method is presented to obtain price levels for products and then, a mixed-integer linear programming model is developed. Due to the problem intractability, a simulated annealing algorithm that uses some developed linear relaxation-based heuristics for capacity planning and pricing is presented. Numerical results demonstrate the significance of the model as well as the efficiency of the solution algorithm and linear relaxation-based heuristics. 相似文献

为使企业总体利益最大化,在企业两个或数个不同的分部之间确定适当的价格和产量对一体化经营企业而言极为重要。同时,转移定价可作为一种分部之间的激励机制。采用边际成本等于边际收益的方法,可以得到不同的市场结构中最优的转移价格和产量。 相似文献

Today, brick-and-mortar retailers with integrated online shops have many alternatives to increase their customers’ shopping satisfaction: They could invest in (for the retailers) new physical store technologies (e.g., beacons or magical mirrors if not implemented up to now), new online shop technologies (e.g., visual tagging or webcams), or in new less technology-based improvement options (e.g. events or product testing). We propose an adapted Kano based stage-gate approach to support multichannel retailers confronted with such selection problems. The approach is applied to a major European sporting goods retailer. 37 improvement options are pre-selected and evaluated by current and potential customers. It can be shown that instore returns, instore services, reserve&collect, click&collect, customization, product testing, and magical mirrors are drivers of satisfaction for the current customers and should be implemented in contrast to, e.g., geofencing or beacons. The potential customers are more technology-savvy, but show similar categorizations as a current customer segment and so confirm the selection. 相似文献

Market orientation has received substantial academic and practitioner interest over the last decade. However, previous research has not addressed the issue how a company's management systems can be designed in a market-oriented way. Starting from a systems-based perspective of management, the authors develop and validate a scale measuring the extent of market orientation of a business organization's management systems including the organization system, the information system, the planning system, the controlling system, and the human resource management system. Empirical results reveal a substantial positive impact of market-oriented management on market performance which in turn leads to financial performance. 相似文献

行贿直接诱发受贿．是腐败产生的温床,严查行贿犯罪是当前我国遏制腐败的必然要求。从实体法上解决查处行贿犯罪面临的“瓶颈”问题是刑法本身的社会性、刑事程序的僵化性、配套法律的欠缺性和国际条约的普适性之必然选择。为此,我们应该围绕严查的标准和需求,检视现行实体法存在的诸多不足,在此基础上,从罪与刑两个方面共同着力,既要严密法网,扩大行为犯罪化,加大追诉力度,又要疏缓刑罚,实现犯罪轻刑化,增加侦破几率．以此切实达到严查行贿犯罪之目的。 相似文献

Previous studies already established the idea of a partnership in which HR professionals and line managers share an organisation’s HRM responsibility. Yet, this relationship is often plagued by conflicts and other obstacles. As such, a perceptual discrepancy is likely to exist between both parties on the degree of HR devolution, which may eventually lead to bad performance. Using survey data, we empirically analyse which factors may explain a perceptual discrepancy between HR professionals and line managers on the latter group’s role in HRM. Results show that the HR-line discrepancy on the degree of HR devolution is rooted in differences in perception on several other factors, including organisational support, (personnel) red tape, the line’s individual capacity and age. Overall, though, it is a matter of understanding both HR’s expectations and the line’s experiences in all aspects of their partnership. 相似文献

Data envelopment analysis (DEA) has recently become relatively popular with road safety experts. Therefore, various decision-making units (DMUs), such as EU countries, have been assessed in terms of road safety performance (RSP). However, the DEA has been criticized because it evaluates DMUs based only on the concept of self-assessment, and, therefore does not provide a unique ranking for DMUs. Therefore, cross efficiency method (CEM) was developed to overcome this shortcoming. Peer-evaluations in addition to self-evaluation have made the CEM to be recognized as an effective method for ranking DMUs. The traditional CEM is based only on the standard CCR (Charnes, Cooper and Rhodes) model, and it evaluates DMUs according to their position relative to the best practice frontier while neglecting the worst practice frontier. However, the DMUs can also be assessed based on their position relative to the worst practice frontier. In this regard, the present study aims to provide a double-frontier CEM for assessing RSP by taking into account the best and worst frontiers simultaneously. For this purpose, the cross efficiency and cross anti-efficiency matrices are generated.Even though a weighted average method (WAM) is most frequently used for cross efficiency aggregation, the decision maker's (DM) preference structure may not be reflected. For this reason, the present study mainly focuses on the evidential reasoning approach (ERA), as a nonlinear aggregation method, rather than the linear WAM. Equal weights are often used for cross efficiency aggregation; consequently, the effect of the DM's subjective judgments in obtaining the overall efficiency is ignored. In this respect, the minimax entropy approach (MEA) and the maximum disparity approach (MMDA) are applied for determining the ordered weighted averaging (OWA) operator weights for cross efficiency aggregation. The weighted cross efficiencies and cross anti-efficiencies are then aggregated using the ERA. Finally, the proposed method, called DF-CEM-ERA, is used to evaluate the RSP of EU countries as well as Serbian police departments (PDs). 相似文献

This paper aims to estimate a parsimonious data-congruent model for aggregate real consumption in Japan using quarterly data over the past two decades. Testing co-breaking, cointegration and weak exogeneity plays an important role in pursuing the model reduction. It is demonstrated that co-breaking removes a deterministic shift caused by the collapse of the bubble economy in Japan in the early 1990s. Multivariate cointegration analysis then reveals that inflation plays a critical role in accounting for the long-run behaviour of the aggregate consumption. Further analysis finds that inflation and aggregate income are weakly exogenous with respect to a set of parameters of interest. Finally, a parsimonious data-congruent model for the aggregate consumption is estimated conditional on the set of weakly exogenous variables. 相似文献

We contribute to the debate on how to assess the size of the underground (or shadow) economy by proposing a reinterpretation of the traditional Currency Demand Approach (CDA) à la Tanzi. In particular, we introduce three main innovations. First, we take a direct measure of the value of cash transactions—the flow of cash withdrawn from bank accounts relative to total non‐cash payments—as the dependent variable in the money demand equation. This allows us to avoid unrealistic assumptions on the velocity of money and the absence of any irregular transaction in a given year, overcoming two severe critiques to the traditional CDA. Second, in place of the tax burden level, usually intended as the main motivation for non‐compliance, we include among the covariates two direct indicators of detected tax evasion. Finally, we control also for the role of illegal production considering crimes like drug dealing and prostitution, which—jointly with the shadow economy—contributes to the larger aggregate of the non‐observed economy and represents a significant component of total cash payments. We propose then an application of this “modified CDA” to a panel of 91 Italian provinces for the years 2005–08. 相似文献
