TL;DR: In this paper, the authors proposed an objective, quantitative decision analysis approach to position products and services within the Kraljic Portfolio Matrix (KPM) to help overcome the qualitative nature of the model, which results in a subjective method for weighting and positioning suppliers or commodities in the various quadrants.

TL;DR: KraljicMatrix allows a firm to strategically analyze its purchasing portfolio with single and multi-attribute value analysis to measure purchasing characteristics and provides useful functions to identify the preferred single utility slope based on subject matter expert inputs.
Abstract: KraljicMatrix is an R package (R Core Team (2016)) that implements a quantified approach to the Kraljic Matrix (Kraljic (1983)) introduced by Montgomery et al. (Montgomery, Ogden, and Boehmke (2017)). It allows a firm to strategically analyze its purchasing portfolio with singleand multi-attribute value analysis to measure purchasing characteristics. In addition KraljicMatrix also provides useful functions to identify the preferred single utility slope based on subject matter expert inputs, assign and place purchases within the Kraljic Matrix, and perform sensitivity analysis.

Journal ArticleDOI
TL;DR: The proposed framework has been designed to facilitate dynamic learning mechanisms through a feedback loop to continuously update the three integrated models and in turn allow managers to gain a strategic perspective of the evolution of buyer-supplier relationships, the influence of previous decisions and external factors.

Journal ArticleDOI
TL;DR: In this paper , the authors formalized a framework that provides guidance on how supplier selection should be formulated and approached for different types of items segmented in Kraljic's portfolio matrix and production policies.

TL;DR: In this article, the authors developed a Humanitarian Purchasing Matrix to guide purchasing strategies for relief items in humanitarian operations, based on the Analytic Hierarchy Process to classify the items in the matrix, an illustrative example is used as an empirical test for the proposed Humanitarian purchasing matrix.
Abstract: The purpose of this paper is to develop a Humanitarian Purchasing Matrix to guide purchasing strategies for relief items in humanitarian operations.,The research synthesizes the structures of a Purchasing Portfolio Model and the characteristics of purchasing in humanitarian operations, validating them with academics and practitioners to develop a Humanitarian Purchasing Matrix. Then, based on the Analytic Hierarchy Process to classify the relief items in the matrix, an illustrative example is used as an empirical test for the proposed Humanitarian Purchasing Matrix.,The academic literature on purchasing in general and purchasing in humanitarian operations share some similarities in terms of “Importance of Purchasing” and “Complexity of Supply Market” dimensions. Moreover, the analysis of such criteria supports the definition of purchasing strategies for different relief items in humanitarian operations.,The Humanitarian Purchasing Matrix can be considered a tool/guide for professionals of humanitarian organizations in the adoption of purchasing strategies for the different relief items purchased for humanitarian operations.,Considering a scenario of a constant increase in the variety of relief items, the high purchasing volume and the pressure to more efficient relief operations, the research discusses the intersectionality of business purchasing models and the purchasing characteristics of humanitarian operations. Moreover, the research deliveries a tool/guide to the adoption of purchasing strategies that are composed of criteria observed in the literature and suggested by both humanitarian logistic academics and practitioners.

TL;DR: An integrated model for supplier selection is proposed, considering inventory management and inbound transportation, and reveals that criteria in supplier selection should be given a different priority depending on the characteristics of the items, and the effectiveness of disruption mitigation strategies depends on the disruption characteristics.
Abstract: In the current global market, managing supply is not a straightforward process and it becomes even more complex as uncertainty and disruptions occur. In order to mitigate their impact, the selectio...

TL;DR: In this article, the authors developed a conceptual model to explain how the severity and timing uncertainty of expected tariff increases influence a firm's speed of adapting to the changing tariff environment, and explored firms' propensity to form or delete ties to suppliers, which influences supply base complexity.
