PurposeThe traditional newsvendor model has focused on deriving the optimal order quantity that minimises the balance between stocking too much or too less number of products. However, the managers make inventory decisions based on intuitions and shortcuts, which may involve human errors and biases. The effect of cognitive biases and heuristics influencing the inventory ordering decisions in newsvendor settings is highlighted. The advancement of research associated to the newsvendor biases is reviewed to appreciate the behavioral aspects of the minds underlying this process.Design/methodology/approachThe use of experimental and non-experimental methods to investigate the ordering behaviour of newsvendors is described and we present a framework of the existing literature and highlight the research gaps to point to future research possibilities and priorities.FindingsThe proposed framework gives a systematic approach to confirm the existence of a substantial scope of research opportunities and points to specific areas for further research. It synthesizes the existing results of behavioral newsvendor research and will act as a key reference paper. In addition, it will help the practitioners and software tool vendors to comprehend the behavioral perspective of newsvendor preferences and design strategies to mitigate this effect. The insights will be helpful for academicians, researchers and practitioners working in the areas of experimental economics, behavioral economics, behavioral operations, bounded rationality theory, newsvendor modelling and supply chain contracts.Originality/valueA summary of literature in this evolving area of research is very scarce. Considering the impact of behavioral economics on managerial decisions in the contemporary world, it is highly important to have an educational summary which can act as a tool for the practitioners and researchers in the area of behavioral operations management.

PurposeThe purpose of this work is to gain insights about Lean Six Sigma (LSS) in the Indian context by reviewing the related literature for one decade based on various perspectives, such as author profile, year of publication, type of firm, type of methodology used, type of industry for which the research work is carried out and the key findings from the research.Design/methodology/approachThis study reviews the research related to LSS from the articles published in the reputed journals. The literature used for reviewing is derived from the sources, including Science direct, Google scholar, IEEE, Taylor and Francis Group, Emerald Insight, Springer, Inderscience and Elsevier during the period between 2010 and 2021. Totally, the authors have included 141 LSS-related research articles that are published in the Indian context. The keywords used are Lean Six Sigma, Lean Six Sigma in the Indian context, Lean Sigma and LSS to identify and consolidate the research papers published during this timeframe.FindingsThe research papers collected from various reputed journals, including Scopus and non- Scopus enlisted, are classified and grouped under various categories to identify the class of author who publishes more in this field, research trend over the years, the type of firm which implements LSS, the research methodology which is commonly used in LSS and related research and also the key takeaway from these articles are highlighted. Further, the authors have also identified the major contributions of researchers in various sectors during this period in India.Originality/valueThis classification framework and the systematic review help in identifying the research gap and in giving directions for future researchers. It will be useful for researchers and practitioners working on the area of LSS, rural and urban entrepreneurs, start-up managers, professionals working in micro, small and medium enterprises (MSMEs) and executives of the Make in India Project to make India as Aatmanirbhar Bharat Abhiyan. Further, the clear direction of progress over the current decade in manufacturing industries, service sectors and processing industries can help the professionals working in these sectors.

PurposePorts handle a significant portion of international cargo, so the performance of ports plays a major role in the economic development of a country. This paper aims to study how port performance depends on various interdependent factors and how it requires a holistic approach, which accounts for all the necessary criteria that contribute to the overall efficiency and performance.Design/methodology/approachAn integrated fuzzy DEMATEL-TOPSIS approach with an objective to evaluate the operational capability and financial performance of the ports is proposed. A case study is presented with an analysis of the major South Indian ports to assess port operational performance and evaluate various financial ratios to assess financial performance.FindingsThrough a review of the literature and based on the inputs from experts, six criteria affecting the operational performance and six financial criteria were identified. The debt coverage ratios turned out to be the most important, while the liquidity ratios were the least important. The six operational criteria have almost similar importance. The final results indicate a consistent overall performance by the Ennore Port, except during one financial year.Practical implicationsThe proposed solution approach helps to identify and concentrate on the criteria that affect port performance. It will also help to evaluate and understand the dynamics involved in the performance of ports.Originality/valueThis work highlights the key measurable operational and financial criteria that affect the efficiency of ports. The integrated fuzzy DEMATEL-TOPSIS approach provides a better way to evaluate and benchmark port performance.
