Abstract
Purpose
The purpose of this paper is to develop data envelopment analysis (DEA) models and algorithms for efficiency improvement when the inputs and output weights are restricted and there is fixed availability of inputs in the system.
Design/methodology/approach
Limitation on availability of inputs is represented in the form of constant sum of inputs (CSOI) constraint. The amount of excess input of an inefficient decision-making unit (DMU) is redistributed among other DMUs in such a way so that there is no reduction in their efficiency. DEA models have been developed to design the optimum strategy to reallocate the excess input.
Findings
The authors have developed the method for reallocating the excess input among DMUs while under CSOI constraint and parameter weight restrictions. It has been shown that in this work to improve the efficiency of an inefficient DMU one needs the cooperation of selected few DMUs. The working of the models and results have been shown through a case study on carbon dioxide emissions of 32 countries.
Research limitations/implications
The limitation of the study is that only one DMU can expect to benefit from the application of these methods at any given time.
Practical implications
Results of the paper are useful in situations when decision maker is exploring the possibility of transferring the excess resources from underperforming DMUs to the other DMUs to improve the performance.
Originality/value
This strategy of reallocation of excess input will be very useful in situations when decision maker is exploring the possibility of transferring the excess resources from underperforming DMUs to the other DMUs to improve the performance. Unlike the existing works on efficiency improvement under CSOI, this work seeks to address the issue of efficiency improvement when the input/output parameter weights are also restricted.

Abstract
Purpose
The main aim of this paper is to investigate key challenges that hinder sustainable and resilient green supply chain (GSC) building in small and medium-sized enterprises (SMEs) with respect to how they interact after the COVID era.
Design/methodology/approach
Using a questionnaire, policymakers and industry managers from SMEs identify the main obstacles that will affect their resilience. These issues are then discussed with 50 experienced professionals from the top management field and further divided into sustainability and gresilience challenges. The Grey-DEMATEL (Grey sets and Decision-Making Trial and Evaluation Laboratory) has been employed to assess the significance of challenges to SMEs' development of green resilience. Overall, the paper aims to build up a novel decision-making technology for the interconnectedness of green and resilience in the post-pandemic supply chain world.
Findings
The 12 sustainability and gresilience challenges highlighted by experts in the sector were analyzed. Insufficient government assistance and the handling of resources are the most significant challenges to developing a sustainable and gresilient value chain system, according to the study. The study highlights supply chain restructuring, waste reduction management, shortages of skilled manpower and insufficient knowledge of digitalization as key challenges for SMEs to prioritize.
Practical implications
The outcomes of this research are crucial for SMEs building resilient supply networks through the green concept. Policymakers may utilize the data to pinpoint shortcomings in the supply chain for tactical as well as strategic development and improvement.
Originality/value
When it comes to building green resilience and sustainability in an unpredictable business climate, the outcomes of this research will be significant for SMEs.

Abstract
The indigenous and sustainable knowledge possessed by the tribal people and communities plays an extremely important role in the conservation of the climate. As per the United Nations Sustainable Development Goals (UN SDGs), tribal communities play an important role in preserving traditional knowledge, culture, food practices and textiles. The remains of the Indus Valley civilisation highlight the importance of the culture and religion. Animism and the worship of nature to achieve success in routines and tasks have been practised by these tribes for centuries. India is a mosaic of more than 705 different colourful tribes, and each of these tribes has their own identity that differentiates it from the other tribes. With increasing ecological complexities, the knowledge owned by the tribes is extremely useful in the preservation of the climate. This chapter seeks to explore the various hues and colours that constitute the mosaic of Indian tribal culture.

Abstract
Purpose
Small farmers in India are collectivized and legalized as Farmer Producer Companies (FPCs) to progress in agri-food value chains as small agribusiness enterprises. FPCs are dependent on timely information for their sustainability and profitability. Mobile apps are a cost-effective form of information and communication technology. Hence, the purpose of this study is to explore the major determinants of mobile apps adoption by FPCs.
Design/methodology/approach
Quantitative and qualitative data are collected by administering a semi-structured questionnaire and conducting in-depth interviews with board members of 115 FPCs, with a total membership of 30,405 farmers operating in 14 districts of the state of Kerala, India. The logit model is used for quantitative analysis, while dialog mapping is used for qualitative analysis, based on an integrated technology acceptance model and technology organization environment framework.
Findings
Logistic regression results evidence that amongst FPC characteristics, while company size and age are significantly impacting apps adoption, there is no significant association between board size, education level, multiple commodities business or export intention of companies on apps adoption. Digital literacy and technical hands-on training for FPC board members are quintessential to facilitate mobile apps adoption.
Practical implications
The findings are pertinent to policymakers to earmark funds for technical handholding and digital upskilling of FPCs. The need for developing comprehensive, location-centric, farmer-friendly apps by agritech companies is evidenced.
Originality/value
To the best of the authors’ knowledge, this is a pioneering work in the domain of mobile apps adoption from a farmers’ agribusiness enterprise perspective in an emerging market economy using a mixed-methods approach.

Abstract
Purpose
This paper aims to investigate the firm performance of micro, small and medium enterprises (MSMEs) by using artificial intelligence-based supply chain resilience strategies. A theoretical framework shows the relationship between artificial intelligence, supply chain resilience strategy and firm performance.
Design/methodology/approach
A questionnaire is developed to survey the MSMEs of India. A sample size of 307 is considered for the survey. The employees working in MSMEs are targeted responses. The conceptual model developed is tested empirically.
Findings
The study found that eight hypotheses were accepted and two were rejected. There are five mediating variables in the current study. Artificial intelligence, the independent variable, positively affects all five mediators. Then, according to the survey and analysis of the final 307 responses from MSMEs, the mediating variables significantly impact the dependent variable, firm performance.
Research limitations/implications

Abstract
Purpose
The purpose of this research is to study and examine the influence of systematic supply risk management (SRM) on the buyer's firm performance, mainly focussing on the Indian electronics industry.
Design/methodology/approach
The study has framed a set of hypotheses on the risk management model. A thorough literature review and experts' opinion were considered in framing constructs and hypothesis for the model. We adopted self-administration questionnaires mainly focusing on the Indian electronics industry. The derived hypothesis is tested using partial least squares (PLS) method from 140 survey data pertaining to small, medium and large scale industries.
Findings
Study justify that constructs with high loadings for risk identification, risk assessment, risk reduction, and risk monitoring supports all hypothesized relation to better risk management. The model captures superior risk identification, risk control and risk monitoring for overall firm performance, but fails to justify with organization supply risk assessment process on overall firm performance.
Research limitations/implications
The study mainly focused on SRM process on firm performance. Study mainly focused on single survey responses and expert's perceptions on SRM practices in Indian electronics industry.
Practical implications
Research empirically justifies the effects of SRM process on organization performance. Furthermore, effective SRM practices assist decision makers framing corrective strategies to mitigate risk occurrences and their negative impact.
Originality/value
This empirical work provides a deep understanding of SRM process on the Indian electronics industry and their perception towards firm performance. Moreover, this is one of the few empirical studies addressing SRM practices in the Indian electronics industry.
