    Application of ISM technique for analysis of the procurement related attributes in JIT supply chain management
    (Inderscience Publishers, 2014) Mishra, O.P.; Kumar, V.; Garg, D.
    The fierce competition in selling a product has made us have to think differently. The supply chain is one issue in front of each production firm to compete with another and to get privilege of another. The excellence of the supply chain is possible only when the product is of the best quality while being cost competitive. The reduction of the production cost has become the focus point in reducing the overall cost of the supply chain. This paper focuses JIT procurement process in the SC to cut one the overall costs. To estimate the factors affecting the JIT procurement (JP) we have recognised the important attributes from the literatures. A questionnaire-based survey was carried out to give the ranking of the attributes found from literature and then an interpretative structural model (ISM) is prepared to link the levels of importance of the JP attributes among themselves. On the basis of levels of the attributes managerial staff are suggested to focus on the particular issues to make the JP successful, therefore making the JIT supply chain management successful even in the worst scenario.

    Impact of wholesale price discrimination on the profit of chain members under different channel power structures
    (Palgrave Macmillan, 2021) Rofin, T.M.; Mahanty, B.
    The purpose of this paper is to investigate the impact of wholesale price discrimination by a manufacturer on the profitability of chain members in a Retailer—E-tailer dual-channel supply chain for different product categories based on their online channel preference. We have considered two distinct channel power structures in this study, i.e., (i) retailer has higher channel power than the e-tailer and (ii) e-tailer has higher channel power than the retailer. Game-theoretic models are developed to examine the competition between the retailer and e-tailer and to derive their optimal decisions under equal wholesale price strategy and discriminatory wholesale price strategy for the channel power structures considered. Further, a numerical example was employed to quantify the results and to capture the variation with respect to online channel preference of the product. We have found that discriminatory wholesale price strategy is the gainful strategy (i) for a manufacturer dealing with products having high online channel preference under retailer leader structure (ii) for the manufacturer dealing with products having low online channel preference under e-tailer leader structure. Equal wholesale price strategy is the gainful strategy (i) for a manufacturer dealing with products having low online channel preference under retailer leader structure and (ii) for a manufacturer dealing with products having high online channel preference under e-tailer leader structure. The study helps the manufacturers to maximize their profit by adopting the right wholesale price strategy considering the online channel preference of the product and the downstream channel power structure. © 2021, The Author(s), under exclusive licence to Springer Nature Limited.

    Impact of wholesale price discrimination by the manufacturer on the profit of supply chain members
    (Emerald Group Holdings Ltd., 2022) Tm, R.; Mahanty, B.
    Purpose: The purpose of this paper is to investigate the impact of wholesale price discrimination by a manufacturer in a retailer–e-tailer dual-channel supply chain for different product categories based on their online channel preference. Design/methodology/approach: This paper considers a dual-channel supply chain comprising of a retailer and an e-tailer engaged in competition. Game-theoretic models are developed to model the competition between the retailer and e-tailer and to derive their optimal price, optimal order quantity and optimal profit under (1) equal wholesale price strategy and (2) discriminatory wholesale price strategy. Further, a numerical example was employed to quantify the results and to capture the variation with respect to online channel preference of the product. Findings: It is beneficial for the manufacturer to adopt a discriminatory wholesale price strategy for products having both high online channel preference and low online channel preference. However, equal wholesale price strategy is beneficial for the e-tailer and the retailer in the case of products having high online channel preference and in the case of products having low online channel preference, respectively. Practical implications: The study helps the manufacturers to maximize their profit by adopting the right wholesale price strategy considering the online channel preference of the product when the manufacturers are supplying to heterogeneous retailers. Originality/value: There is scant literature on the wholesale price strategy of the manufacturer considering the heterogeneous downstream retailers. This paper contributes the literature by bridging this gap. In addition, the study establishes a link between the wholesale price strategy and online channel preference of the product. © 2020, Emerald Publishing Limited.
