Supply Chain Resilience and Operational Performance: The Role of Digital Technologies in Jordanian Manufacturing Firms

This study aims to analyze the relationship between supply chain resilience (SCR) practices and operational performance and the moderating role of digital technologies in Jordanian manufacturing firms. A descriptive-analytical approach was adopted using a questionnaire based on the study model and previous related literature. Four hundred supply chain (SC)-related managers within seventy-one firms were reached to collect the needed data; three hundred and seventy-two complete questionnaires were analyzed. The results revealed that the level of SCR practices and operational performance was high; SCR (with its sub-dimensions: SC agility (SCA), SC flexibility (SCF), and SC collaboration (SCC)) had a significant positive relationship with operational performance; and the appropriate use of digital technologies had a significant moderating impact on the aggregate level of the SCR–operational performance relationship. Finally, research limitations, practical implications, and future research conclude this study.

Operational performance entitling the knowledge of inventory management practices on business performance: a mediational study

Purpose

The purpose of this paper is to examine the impact of knowledge of inventory management practices (KIMP) on operational performance (OP) and business performance (BP). This study emphasized understanding the mediational effect of OPs among KIMP and BP in manufacturing firms of Indian small- and medium-sized enterprises (SMEs).

Design/methodology/approach

This study analysed the above relationship from the data collected from 351 key officials of 170 Indian SMEs. The detailed analysis, including reliability, validity and testing hypothesis, was done in advanced SmartPLS-SEM 3.3.3 software.

Findings

The findings show that KIMP directly influences OP; thus, a company's OP significantly impacts the overall BP. The KIMP has no significant effect on BP. In line with this, the study findings demonstrate a significant, high mediation effect of OPs between KIMP and BP.

Originality/value

The KIMP on OP has been sparsely studied earlier, and neither have they conceptualized in understanding its impact on BP. In such tumultuous times, key manufacturing executives should stress the importance of KIMP as a comprehensive perspective.

Investigating the interaction of factors for implementing additive manufacturing to build an antifragile supply chain: TISM-MICMAC approach

The outbreak of the Covid-19 pandemic has come across as an exogenous shock to the firms and their supply chains. It has led firms to rethink and rework their existing robust and resilient supply chains. The purpose of this study is to move beyond robustness and resilience and shift to an antifragile supply chain that sees disorder as an opportunity to learn and grow. In this study, various factors to attain an antifragile supply chain have been identified through literature review and experts’ opinions. Using TISM-MICMAC, structural relationships among these factors have been developed, and, then the factors have been classified as drivers or dependents. The study reveals the importance of having proactive top management as a major driving power to build an antifragile supply chain. Development of a strategy for collaboration and innovation, development of a skilled workforce for technology adoption, and resource allocation for digitalization are some other factors with strong driving power. The novelty of the study lies in its effort to drive the attention of researchers and practitioners towards thinking beyond robustness and resilience and shifting towards antifragility. The study will help firms in strategic decision-making for the adoption of additive manufacturing technology to develop antifragility in the supply chain and save itself from negative consequences in the face of disruption.

Effect of information sharing in supply chains: understanding the roles of supply chain visibility, agility, collaboration on supply chain performance

Purpose

Exploring ways to acquire, sustain and improve competitive positions in supply chains through information sharing, supply chain visibility, collaboration and agility have been essential for scholars and practitioners. Basing on the relational view, resource based view and the extended resource based view, this study assesses the critical role of information sharing in supply chains through emphasizing its effect on supply chain visibility, collaboration, agility and supply chain performance. Particularly, the study proposes that information sharing, supply chain visibility, collaboration and agility collectively have crucial direct and indirect influences on supply chain performance which lead to superior gains, competitiveness and flexibility.

Design/methodology/approach

The study adopted a survey research design, a quantitative approach and partial least square structural equation modeling (PLS-SEM) in making data analysis and interpretations due to its suitability for predictive research models.

Findings

The results indicate information sharing positively and significantly influenced supply chain visibility, collaboration, agility and performance. Supply chain visibility presented significant effects on collaboration, agility and performance, while supply chain collaboration and agility had significant impact on supply chain performance. The study findings connote that information sharing is key to enhancing competitive gains and superior supply chain performance.

Originality/value

The study is among the few to probe on how information sharing as a variable interacts with supply chain visibility, collaboration, agility and performance. Although, information sharing has received a lot of attention in supply chains, this study is among the first to capture the study variables in a single model and thus, exposes the vital need for information sharing in improving supply chain performance seeing that it ensured significant and robust impacts on the study variables.

Comparative analysis of environment losses in steel manufacturing supply chain using Taguchi loss function and design of experiments

Purpose

The objective of this paper is to compare and evaluate the environmental performance of steel supply chains considering relevant environmental loss factors using Taguchi loss function (TLF) and design of experiments (DOE).

Design/methodology/approach

The different environmental loss factors in steel manufacturing supply chain were studied and the significant factors were identified. Their combined contributions along the significant factors were estimated using TLF and DOEs comparing environment losses at different scenarios.

Findings

The proposed methodology using TLF and DOEs was applied to three Indian steel manufacturing companies (Company A, Company B and Company C). The Company A with minimal average environmental loss score is found to be operating its supply chain with higher efficiency and has better environmental performance compared to the other two companies (B and C).

Research limitations/implications

The results obtained are based on the study carried out in three Indian steel manufacturing companies. Therefore, the results cannot be generalized.

Practical implications

This paper will definitely show the direction for comparative environmental performance assessment of manufacturing industries in general and steel industries in specific considering environmental loss factors and environmental conditions. It determines individual performance across each environmental loss factor and their combined impact.

Originality/value

Although there is a need to have comparative performance analysis with respect to environmental losses among steel companies in developing countries such as India, but hardly any study has been reported in this direction. This work will definitely add the value to the supply chain literature in general and environment losses in steel manufacturing supply chain in specific.
