Statistical Quality Study of the Parts Produced in an Automobile Industry: A Daimler India Case Study

Every manufacturing industry considers defect-free production in this competitive era. Though it is practically impossible to improve the rate of defect minimization, statistical tools can be used. In this case study, we take data from Daimler India, an automobile part manufacturing industry specialized in manufacturing OEM tools like chassis, oil filter nipple, and so on, and study how many defects are made during the day. The defect-causing process was eliminated after using statistical quality control tools such as np charts and cumulative sum charts, resulting in higher production quality.

TQM, employee outcomes and performance: the contingency effect of environmental uncertainty

PurposeThe purpose of this study is to investigate the relationship between total quality management (TQM), employee outcomes and performance. Moreover, how environmental uncertainty (EU) influences the relationship between employee outcomes and performance is regarded in the context of automobile part manufacturing and suppliers of Iran. Four theories namely resource-based view theory, ability, motivation, opportunity framework, contingency theory and quality management theory have been adopted in this research.Design/methodology/approachA research project is conducted in 191 automobile part manufacturing and suppliers plants using the questionnaire method. Confirmatory factor analysis is applied to assess the reliability and validity of the measurement instrument. The correlations between latent constructs are examined through partial least squares method.FindingsThe results show positive relationship between TQM, employee outcome and performance. The EU also moderates the relationship between employee outcome and performance.Research limitations/implicationsIt is recommended that some contextual factors such as culture be noticed in future research studies. Data were collected from Iranian automobile part manufacturing and suppliers plants, which may limit the generalization of results to other organizations in other countries.Practical implicationsIn this paper, some beneficial insights are addressed to assist managers in recognizing the organizational problems, which weaken implementing TQM, employee outcomes and the effect of EU on organizations.Social implicationsBy improving the quality of management practices and employee outcomes, the society gains benefits such as customer satisfaction.Originality/valueThis study contributes to the TQM advance and human resource management literature and provides better foundations for employee outcomes improvement through TQM practices in the Middle East. By investigating the effect of EU, this study fills the current gap in this field.

The impact of TQM practices on organizational learning case study: automobile part manufacturing and suppliers of Iran

Purpose The purpose of this paper is to determine the correlations between TQM and organizational learning in the context of automobile part manufacturing and suppliers of Iran. Design/methodology/approach A research project is carried out in 191 automobile part manufacturing and suppliers plants, using the questionnaire method. Confirmatory Factor Analysis (CFA) is applied to assess the measurement instrument reliability and validity. The correlations between latent constructs are examined through Partial Least Squares (PLS) method. Findings Findings indicate that, both, the core and infrastructure aspects of QM practices have significant positive effect on organizational learning. At the lower levels, HRM and information and analysis contribute to enhancement of the organizational learning. Research limitations/implications It is recommended that a more complete construct be designed for measuring the organizational learning. Some contextual factors such as culture need to be noticed in future researches. Practical implications in this article some beneficial insights are addressed to assist managers in recognizing the organizational problems which weaken the organizational learning. Originality/value This study contributes to the TQM advance, organizational learning research literature and provides better foundations for organizational learning improvement through TQM practices in the Middle East. By investigating the correlations between infrastructure and core QM practices and organizational learning, this study fills the current gap in this field.

Simulation Analysis of HPDC Process with Automobile Part by CAE

In present casting industries, product development paradigm is shifting from traditional trial-and-error to proof-of-concept based on CAE-enabled simulation. In the new production development paradigm, CAE simulation plays an important role because it models the entire casting process and reveals the dynamic behavior of the casting system in working conditions. In this research, Computer Aided Engineering (CAE) simulation was performed by using the simulation software (AnyCasting) in order to optimize casting design of an automobile part (Upper Oil Pan) which is well known and complicated to achieve a good casting layout. The simulation results were analyzed and compared carefully in order to apply them into the production die-casting mold. During the filling process, internal porosities caused by air entrapments were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were also predicted.
