Purpose -The aim of this paper is to present a purchasing portfolio model for determining purchasing strategy at the component level of a product to support business strategy, addressing weaknesses in the often cited Kraljic-type models. The work draws on Fisher's model to match supply strategy to product nature. However, Fisher's model was criticised very recently by Lo and Power in this journal because it is unclear how the "leagile" option should fit into it. This paper addresses this issue. Design/methodology/approach -The new portfolio model is based on the literature, particularly Fisher's seminal work. It is then applied to two case studies; an electric boiler manufacturer and an elevator manufacturer, both in South Korea. The analytic hierarchy process (AHP) is used to position purchased components in the model. Findings -Different purchasing strategies should be assigned to different components according to their impact on the competitive priorities. As the electric boiler is a functional product, while the elevator is an innovative product, the case studies show how this can vary across the two product-types identified by Fisher.Research limitations/implications -The new model has been tested on only two case studies, which limits the ability to generalise the findings. Future work will use the lean and agile purchasing portfolio model in research and knowledge exchange activities with other industrial partners to further develop and test its efficacy. Originality/value -The new model captures the finding of Fisher and others that products should be classified as functional or innovation to determine their suitability for lean or agile supply respectively. However, this classification is extended here to the component level and with the addition of the leagile and non-strategic supply options, and it depends on the impact a component has on the four competitive priorities; cost, quality, time and flexibility.
The measured g factor and the corresponding emission zone were evaluated by theoretical analysis based on the Müller matrix method by increasing the thickness of the hole transport layer (TPBi) in the twisted configuration of conjugate polymer (F8BT).
International audienceA new approach to purchasing portfolio modelling, stemming from Kraljic's matrix, for developing purchasing strategies that are aligned with competitive priorities, is developed to address the weaknesses of existing approaches that are preventing widespread application, especially in SMEs. The importance of strategic purchasing to achieving competitive priorities and the need to align it with business strategy is argued through a literature review, which is also used to establish that purchasing portfolio modelling is an effective tool in achieving this alignment. The new approach is applied to two South Korean elevator manufacturers
Abstract. The main object of this paper is to present generalization of extended beta function, extended hypergeometric and confluent hypergeometric function introduced by Chaudhry et al. and obtained various integral representations, properties of beta function, Mellin transform, beta distribution, differentiation formulas, transform formulas, recurrence relations, summation formula for these new generalization.
