The process engineers need to execute the process with an optimum setting which would simultaneously meet the requirements on multiple response variables. This can be achieved by using a simultaneous optimisation of multiple characteristics methodology. A lot of research has been carried out in the field of simultaneous optimisation of characteristics. Most of this research focuses on optimising multiple continuous characteristics only. This paper is a case study on the simultaneous optimisation of continuous and categorical characteristics. The sprint productivity and defect proneness of the agile software development process is simultaneously optimised using fuzzy optimisation approach. The optimum obtained by the suggested methodology is superior to the ones obtained by optimising the responses separately. Even though the case study is on optimising only two characteristics, the methodology can be generalised to optimise many characteristics simultaneously.","PeriodicalId":38209,"journal":{"name":"International Journal of Quality Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijqet.2019.104885","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study attempts to develop and validate a QMP scale for manufacturing SMEs. Using Pareto analysis vital QMP factors were identified and questionnaire was administered to 750 SMEs with 68.5% response rate. In order to extract and validate the latent factors, exploratory factor analysis coupled with confirmatory factor analysis was used. Further, structural equation modelling (SEM) was deployed for determining interrelationships of extracted factors. This resulted in seven-QMP factors with R = (0.50-0.81) and R-squared values ranged between 0.23-0.66 representing the variation in 35 items. The study contributes to QMP literature, by bestowing empirical data on QMP factors which are more appropriate for manufacturing SMEs. Though the study was conducted in Indian SMEs context, the research outcomes may be applicable for general manufacturing firms with slight modifications.","PeriodicalId":38209,"journal":{"name":"International Journal of Quality Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijqet.2019.104886","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vane type gas motor, the prime mover of the system, is a critical subsystem with intricate dynamic elements such as rotor, bearings, vanes and speed regulator. Failure prevention of such critical systems, which is of paramount importance to the success of a launch vehicle mission, depends on making the design robust and ensuring that the critical parameters of the system hardware are within the specified range to give optimal performance. This paper addresses the strategies for achieving the design robustness through severe environmental stress testing and realisation of system hardware complying with quality requirements, which are essential for failure prevention. Towards this, critical environments for the gas motor have been identified and testing extended much beyond the system qualification levels, inducing failures. The test observations and data are analysed critically and design modifications made for broadening the operating environments. The quality systems and procedures for the system hardware are strengthened to assure reliable performance of the gas motor.","PeriodicalId":38209,"journal":{"name":"International Journal of Quality Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this paper is to provide an overview of Lean and Six Sigma applications in the healthcare sector. The work done by many researchers in healthcare industry is discussed. Literature survey shows that most of the studies (42%) are focused on reducing processing time. It is also found that number of studies focused on reducing processing time never goes out of phase. The Pareto chart analysis was performed for number of studies in various countries and different departments. It is found that more than 50% of studies were carried out in the USA only and 22% of the studies were performed in emergency department in various countries. The matrix plots are shown for number of studies in different countries and different departments throughout the time line starting from the year 2000 to till date. It is also found that Lean and Six Sigma methodologies were uniformly applied in emergency and surgery departments, whereas in case of countries; only the USA shows continuous applications of Lean and Six Sigma techniques.","PeriodicalId":38209,"journal":{"name":"International Journal of Quality Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41436271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The factors were electroplating period, gold concentration, the electric current and the electroplating temperature. Each factor had two levels. There were four responses collected, that were average gold thickness (Y1), minimum value of gold thickness (Y2), standard deviation of gold thickness (Y3) and average of gold on stainless steel sheet (Y4). 0.05 significance level was used. The results showed that the appropriate parameters were 17 minutes of electroplating period, 0.4 gram per litre of gold concentration, 0.6 amperes per square decimetre of electric current and 60 degree Celsius of electroplating temperature. The experiment could reduce the electroplating period by 4.20 minutes, the average gold thickness jig by 0.13 micron, minimum of gold thickness by 0.19 micron, and average gold percentage by 3.91 percent. These results reduced specification from maximum value of thickness from 3.75 micron to 3.55 micron and mid-thickness average from 3.50 micron to 3.45 micron.","PeriodicalId":38209,"journal":{"name":"International Journal of Quality Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41528621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
