This paper develops an approach to evaluating designs for digitalisation interventions in purchasing and supply management (PSM), and identifies some fundamental design principles for such interventions. A set of advanced technologies for digitalisation and a theory-based set of seven value drivers for PSM are identified for the proposed grid to facilitate the design of applications and interventions for digitalising PSM. The grid relates the digital technologies to the PSM value drivers in a matrix-like manner, allowing the structured consideration of the space defined by these two dimensions. The proposed approach to the strategic evolution of digitalisation in PSM is tested and its utility is demonstrated in analyses of practitioner literature and multiple case-study-based perspectives on PSM digitalisation. Two fundamental design principles relating to the use of the grid, or to the filling of its space, are set out, thus the research provides new theoretical perspectives on the design of advanced forms of PSM digitalisation. The proposed grid may be used in application design, communicating current and future states of PSM digitalisation to stakeholders, and specifically in developing a future-oriented strategy with a digitalization element for the PSM function. 相似文献

This paper reviews some recent blockchain‐based applications for information capture, distribution and preservation. As part of that review, this paper examines two key concerns with current blockchain designs for accounting and supply chain transactions: data independence and multiple semantic models for the same information distribution problem. Blockchain applications typically integrate database, application and presentation tiers all in the same ledger. This results in a general inability to query information in the ledger and other concerns. Further, since most applications appear to be private blockchain applications, there is a concern of agents needing to accommodate multiple blockchains depending on who their trading partners are and what they request. Finally, this paper uses a distributed database to design a ‘blockchain‐like’ system for virtual organizations. 相似文献

Packaging design as a medium for brand communication has a strong impact on the point-of-purchase decision. Therefore, marketers need a keen understanding of how packaging design influences brand perception. Although many studies have investigated the impact of design elements like color or typeface, few have examined the impact of holistic variables like the degree of elaborateness. This study proposes to fill this gap by investigating the influence of the degree of simplicity/complexity in package design on brand perception. The topic is first investigated through a multidisciplinary approach mobilizing the fields of semiotics, art history and marketing. Then, we conduct an experiment in which three bottles of Champagne operationalizing three levels of simplicity/complexity are tested with a sample of 305 consumers. The results indicate that the simplicity/complexity of a package design has a significant impact on brand perception, with simplicity being associated with modernity, reliability, authenticity, success and sobriety and complexity with seniority, joy, imagination, charm, femininity and sophistication. 相似文献

While conjoint analysis has been applied in a wide variety of different contexts in Marketing, most applications fail to explicitly consider retaliatory reactions from competitors. In this paper, a methodological extension is developed for conjoint analysis by explicitly modeling competition in a game theoretic context. The Nash equilibrium concept is employed to model competitive reactions to produce design, and its implications for reactive product strategies are discussed. The optimal product design problem for each firm is formulated as a nonlinear integer programming problem, which is solved via a specialized branch and bound method combined with a heuristic. In order to compute a Nash equilibrium, a sequential iterative procedure is proposed. The proposed procedure is illustrated under several scenarios of competition using previously published conjoint data.This research has been supported by the Henry Rutgers Research Fellowship, Rutgers University. 相似文献

博弈理论是当代主流经济学发展最迅速和影响最大的分支学科之一。其中,进化博弈理论由于引入了“进化稳定策略”(ESS)的概念,有效解决了博弈双方有限理性的现实问题,在解释经济管理现象时更具说服力和生命力。本文结合人民银行实际,通过构建进化博弈理论的复制动态模型,试述人民银行员工激励路径的选择及机制设计的有关问题。 相似文献
