Automated chopper gun trajectory planning (CGTP) for spray forming is highly desirable for today's automotive manufacturing. Generating chopper gun trajectories for free‐form surfaces to satisfy material distribution requirements is still highly challenging due to the complexity of the problems. In this paper, a user‐friendly software for automated CGTP has been developed. The CGTP software can take different formats of the CAD models of parts. A chopper gun trajectory is generated based on the CAD model of a part, chopper gun model, and constraints. A part is partitioned into patches to satisfy the given constraints. A trajectory integration algorithm is developed to integrate the trajectories of the patches to form a trajectory for the part. The CGTP software has been tested by Ford Motor Company and achieved satisfactory results.

Industry 4.0 accelerates the performance of supply chains, in particular, the reduction in supply chain cost (SCC) and improvement in supply chain flexibility (SCF). The aim of this study is to examine the role of Industry 4.0 on SCC and SCF, using network theory to explain the interrelationships.

Data were collected from 182 manufacturing firms in Turkey. The partial least square structural equation modelling (PLS-SEM) was employed in testing the research hypotheses.

The results showed that Industry 4.0 positively affects SCC; however, no direct relationship was found between Industry 4.0 and SCF. Moreover, SCC was found to have a positive impact on SCF, while SCC was found to mediate the relationship between Industry 4.0 and SCF. An additional finding was that customer integration (CI) moderates the relationship between Industry 4.0 and SCC; however, CI does not moderate the relationship between Industry 4.0 and SCF.

The research validates the role of Industry 4.0 on supply chain processes and thus provides valuable insights into supply chain practitioners and decision-makers interested in Industry 4.0 for supply chain management.

In view of the limited number of studies, this study empirically contributes to the literature on the relationships among Industry 4.0, SCC, SCF and CI.

This study investigates the effect of supervisor-directed organizational citizenship behavior (OCB) on leader–member exchange (LMX), the moderating role of impression management motives on this relationship, the effect of LMX on organizational and interpersonal deviance and the mediating effect of LMX on the relationship between supervisor-directed OCB and deviant behaviors.

This study uses a survey questionnaire to collect data. Respondents were 342 nonmanagerial employees working in Surabaya Raya, Indonesia. Hypothesis testing is done using Partial least squares structural equation modeling (PLS-SEM).

The results show that supervisor-directed OCB is positively related to LMX, and LMX is negatively related to organizational deviance but not significantly related to interpersonal deviance. The study also finds that impression management motives moderate the positive relationship between supervisor-directed OCB and LMX. Furthermore, LMX mediates the relationship between supervisor-directed OCB and organizational deviance, but not interpersonal deviance.

This study suggests the importance of human resource management (HRM) activities and managers being aware of subordinate OCB motives and the impact of LMX on interpersonal and organizational deviance, as well as what supervisors need to do to reduce these negative effects.

Few studies examined the relationship between supervisor-directed OCB and workplace deviance behaviors (WDBs). This study provides a mechanism of their relationship by considering LMX as a mediator. Also, heretofore the existing studies tend to focus more on LMX as an antecedent of OCB. This study provides an understanding of OCB as an antecedent of LMX with the moderating effect of impression management motives.
