Abstract
Over the past decade, JIT approach for designing and operating lines has evolved to compete on time dimensions. Traditionally, the lines designed and operated using line balancing approach are considered optimal. Uses simulation methodology to compare each of these approaches under various levels of system variability and total inventory in the system. Shows that when system variability is low, the JIT line produces lower cycle time at almost all levels of total inventory in the system. However, when system variability is high the balanced line yields lower cycle time, especially at lower levels of inventory in the system.

Abstract
Procedures to reduce set‐up times at individual machines have been well documented; however, very little research has been conducted on developing an effective strategy to prioritize set‐up reduction procedures in a multi‐machine facility. Describes a new and innovative way – a throughput approach – to prioritize set‐up reduction procedures in a multi‐machine production system.

Abstract
Over the past decade two approaches, just‐in‐time (JIT) and theory of constraints (TOC), for designing and operating production lines have developed, each claiming to be the “correct” way. In addition there are still those who maintain that line balanced (whenever possible) is the optimal method. This study uses simulation to compare each of these approaches for designing and operating production lines under various levels of processing time variability, station downtime, and total system inventory. Not surprisingly, the JIT approach appears to work best when system variability is low. The TOC approach works best when system variability is high. This shows that lines designed using TOC principles perform significantly better than JIT lines when inventory is low, and JIT lines perform significantly better than TOC lines as inventory is added to the system. The traditionally balanced line did not perform best under any of the conditions used in this study.

Abstract
Purpose
The purpose of this study is to determine the current status of Sustainable Lean Six Sigma (SLSS) practices execution in the industries by identifying the research gaps and also methodologies that are applied by different researchers and practitioners.
Design/methodology/approach
To find the current status of SLSS practices all over world, the literature review of the articles available through SCOPUS data base is given in different categories such as a country-wise and year-wise publication of the articles, journal-wise publication of articles, case study implementation focus in industry and data analysis techniques used by the researchers.
Findings
The different methodologies applied by the researchers and practitioners have been explained and the gaps for further research are identified. The extensive review of articles of last 18 years revealed that there are various opportunities such as quantitative study, framework modeling on the SLSS, and implementation of developed models in different industries, etc. which are required to be explored.
Originality/value
In the present study, a review of 129 articles for the time span of January 2000 to February 2018 is considered. The SCOPUS database was used for selecting the articles for review. A total of 129 articles were considered for the literature review, and the case study implementation in different industries with the focused areas such as cost reduction, defect reduction, economic, environmental and social aspects was explained.

Abstract
Purpose
This paper aims to interpret the multidimensional Asian American identity of immigrant Indians in terms of pan-ethnicity, gender and religion.
Design/methodology/approach
The social construction and experience of race in the US and the intersection of multiethnic Asian American identity with race, gender and religion will be used in critically commenting on the interview of primary ethnic identity of Indian Americans including the pan-ethnic identity of Indians in the US as Asian Americans, the Mar Thoma Church community, the second-generation Patel family's union formation in terms of gender identity.
Findings
The future directives include Asian American Movement (AAM) which is trying to incorporate Indians as pan-ethnic identity assimilation and the process of holding American identity as primary identification of Indians.
Practical implications
Policy recommendations are that the US Census Bureau should include Indian Americans as separate ethnic identity for Indian immigrants like the Chinese Americans. USCIS (US Citizenship and Immigration Services) should reform policies to include the wives of H-4 visa holders. The Department of Homeland Security (DHS) should provide secure living environment for Indian immigrants. The US Department of Labor should provide equal opportunities for women in their immigration policies.
Originality/value
This paper will critically analyze the interview results of primary ethnic identity and justify the hypotheses of Asian American identity of Indians, whether (1) they merge with the American identity as part of cultural assimilation or (2) retain their Asian identity beyond Americanized identity or (3) go beyond both American and Asian identity to restate their Indian ethnicity.
