Abstract
Purpose
Assembly variations, which will propagate along the assembly process, are inevitable and difficult to analyze in Aeronautical Thin‐Walled Structures (ATWS) assembly. The purpose of this paper is to present a new method for analyzing the variation propagation of ATWS with automated riveting.
Design/methodology/approach
The paper addresses the variation propagation model and method by first, forming a novel Stage‐State model to represent the process of automated riveting. Second, the effect of positioning error on assembly variation is defined as propagation variation (PV), and propagation matrix of key characteristic points (KCP) is discussed. Third, the effect between the variations in each stage is defined as expansion variation (EV). According to the analysis of mismatch error and the reference transformation, the expansion matrix is formed.
Findings
The model can solve the variation propagation problem of ATWS with automated riveting efficiently, which is shown as an example of this paper.
Practical implications
The variation obtained by the model and method presented in this paper is in conformity with the variation measured in experiments.
Originality/value
The propagation variation and expansion variation is proposed for the first time, and variations are studied according to novel propagation matrix and expansion matrix.

Abstract
Purpose
Drawing on signaling theory, the purpose of this study is to explore how high-performance work systems (HPWS) interact with leader–member exchange (LMX) to predict employees' proactive behavior and job engagement. Moreover, the present study also proposes the mediating role of job engagement in the interactive effects of HPWS and LMX quality on proactive behavior.
Design/methodology/approach
The data of this study include 228 customer-contact employees and 44 store managers from chain store enterprises in the service sector in Taiwan. The proposed models were tested with hierarchical linear modeling and Monte Carlo simulation.
Findings
The results show a significant interactive effect of HPWS and LMX on job engagement and proactive behavior. In addition, job engagement serves as a vital mechanism linking the interactive effect of HPWS and LMX quality on proactive behavior.
Originality/value
This study uses signaling theory to unpack the question when and how HPWS can be more influential on employees' proactive behavior. In particular, the positive effect of HPWS on proactive behavior is more prominent only when employees enjoy high LMX quality with their respective line managers. In addition, the interactive effects of HPWS and LMX quality on proactive behavior are mediated by job engagement. The findings provide valuable theoretical and managerial contribution by integrating HRM and leadership research.

Abstract
Purpose
The current study aims to deliver a consolidated view of environmental sustainability in cold supply chain performance systems (CSCPS), incorporating theoretical and empirical analysis for improving environmental standards. For this purpose, this study firstly aims to explore and analyze the various crucial challenging factors for environmental sustainability in the cold supply chain (CSC). Secondly, it discovers the most effective sustainable strategies for improving the environmental sustainability of CSCPS.
Design/methodology/approach
The exploration of the crucial challenging factors and the proposed sustainable strategies have been done using a systematic literature review relevant to the sustainable performance of CSC. At the same time, semi-structured brainstorming sessions were conducted with the domain professionals having an industrial and academic background to finalize the strategies. Empirical analysis has been performed using an intuitionistic fuzzy (IF) based hybrid approach of SWARA and COPRAS methods.
Findings
The key findings of the study address that “higher energy consumption during refrigerated transportation and storage” is the most crucial challenge for environmental sustainability in CSC. In addition, “managerial refrain to profit decline due to sustainability implementation” is the second most crucial challenge that hinders the adoption of sustainable practices in CSCs. Meanwhile, the governmental attention to motivating organizations for green adoption and implementation of solar energy-driven refrigeration technologies are the two most important discoveries of the study that might help in improving CSC's environmental performance.
Research limitations/implications
From the implications side, the study enriches and extends the current literature content on CSC sustainability. In addition, it offers sound managerial implications by identifying the challenges that create threats among the management for sustainability adoption and suggesting the most suitable sustainable strategies, which may help the management to raise the environmental performance of their CSC. Besides having various important theoretical and managerial implications for the study, contemplation of only environmental sustainability traits as a broader perspective limits the scope of the study.
Originality/value
The study's main contribution is the exploration of the most crucial challenges imparting obstructions in sustainable development and sustainable strategies, which may get the interest of the CSC players, market leaders, and industrial and academic practitioners working in the domain of CSC sustainability. In addition, this study offers structured theoretical and empirical evidence for CSC's environmental sustainability, thus playing a bridging role between theoretical sustainability concepts and its practical implications in CSC industries.
