This paper investigates the role played by service quality at supplier-manufacturer dyad in small-medium manufacturing units, and presents a model to establish that contribution of both the supplier and manufacturer towards service quality could lead to satisfaction followed by loyalty. The research design for this study includes a combination of literature survey, exploratory interviews with practitioners, and a questionnaire survey conducted through interview schedule from 120 respondents working in different small-medium manufacturing units of North India. Structural equation modeling (SEM) is used for data analysis. The paper develops dual directional scales to evaluate service quality at supplier-manufacturer dyad and tests a set of four propositions. A model showing linkages of manufacturer (manufacturing unit’s) service quality with supplier service quality leading to satisfaction and loyalty is also developed. The model is empirically tested and is found to be fit. This study would be of interest to SME managers particularly engaged in ‘purchase’ function and researchers working on inter-firm supply chains in such units. This study recommends forming strong collaborative relationships with suppliers to achieve a win-win situation.

Altman Z score is an effective tool for measuring a company's financial strength and the possibility of bankruptcy. In this study, the Z score formula was utilized to measure the Indian automobile industry's financial soundness. The financial data of ten automobile companies listed in the National Stoke Exchange (NSE) was taken to analyze both original and emerging market formulae of the Altman Z score. Results suggest that companies of the industry listed in the NSE are financially sound. The study concluded that the Indian automobile industry is sound and robust, and the automobile companies are not prone to financial distress or bankruptcy in the near future.

Facility location models are observed in many diverse areas such as communication networks, transportation, and distribution systems planning. They play significant role in supply chain and operations management and are one of the main well-known topics in strategic agenda of contemporary manufacturing and service companies accompanied by long-lasting effects. We define a new approach for solving stochastic single source capacitated facility location problem (SSSCFLP). Customers with stochastic demand are assigned to set of capacitated facilities that are selected to serve them. It is demonstrated that problem can be transformed to deterministic Single Source Capacitated Facility Location Problem (SSCFLP) for Poisson demand distribution. A hybrid algorithm which combines Lagrangian heuristic with adjusted mixture of Ant colony and Genetic optimization is proposed to find lower and upper bounds for this problem. Computational results of various instances with distinct properties indicate that proposed solving approach is efficient.

The purpose of this study is to create a sustainable business model of Islamic banks in Indonesia through financial and non-financial aspects with financial performance as a mediate variable. The study uses quantitative approach by collecting secondary data of Islamic Banks from financial statements and annual reports over the period 2010-2018. The population of this study is 9 (nine) Islamic banks and the sample of research uses the census method. Data processing methods uses Partial Least Square. The results of the study stated that corporate governance has a significant effect on financial performance, intellectual capital has a significant effect on financial performance and company size has a significant effect on financial performance, but corporate governance has no effect on sustainable business. In addition, intellectual capital has a significant effect on sustainable business but company size has no effect on sustainable business. Moreover, financial performance has a significant effect on sustainable business, financial performance mediated the effect of corporate governance on sustainable business, financial performance partially mediated the effect of intellectual capital on sustainable business and financial performance mediated the effect of company size on sustainable business.

Recently, learning effects have been studied as an interesting topic for scheduling problems, however, most researches have considered single or two-machine settings. Moreover, learning factor has been considered for job times instead of setup times and the same learning effect has been used for all machines. This paper studies the m-machine no-wait flowshop scheduling problem considering truncated learning effect in no-wait flowshop environment. In this problem, setup time is a function of job position in the sequence with a learning truncation parameter and each machine has its own learning effect. In this paper, a mixed integer linear programming is proposed for the problem to solve such problem. This problem is NP-hard so an improved genetic algorithm (GA) and a simulated annealing (SA) algorithm are developed to find near optimal solutions. The accuracy and efficiency of the proposed procedures are tested against different criteria on various instances. Numerical experiments approve that SA outperforms in most instances.

This study was conducted to estimate the determinants as well as the efficiency of Vietnam’s footwear export to 50 trading partners by applying stochastic fronter gravity approach for the period 2001-2018. We found that Vietnam’s footwear export is positively affected by income measured by gross domestic product (GDP), border and landlock situation. The income elasticity of footwear export of Vietnam was about 1.2%. We also showed that the export efficiency of Vietnam’s footwear was not very high with the average ranges from 50.8% to 63.1%. The 10 most efficient countries were Cambodia, Panama, Slovakia, Belgium, Myanmar, Hongkong, Korea, Chile, the US and the Netherlands. We also found that 10 countries with the largest export potential were the US, China, Germany, Japan, Belgium, the UK, Netherlands, Korea, France, Canada. Regarding the determinants of export efficiency, the study provides evidence that trade freedom, financial freedom and importers’ population density positively contributed to efficiency. Our findings also support further integration of Vietnam since membership to many FTA enhances Vietnam’s footwear export efficiency. These FTAs include AFTA, Vietnam-Chile FTA, ASEAN-India FTA, ASEAN-Korean FTA, ASEAN-Japan FTA, ASEAN-China FTA, ASEAN-Australia-New Zealand FTA. Finally, the study recommends a relevant market policy for Vietnam’s footwear export in the coming years. We have provided 4 types of markets with different levels of priorities that Vietnam’s footwear exporters should focus on. The top footwear market priority should be countries with high potential yet low efficiency such as China, Russia, Brazil, Thailand, Sweden, Singapore and Australia.

Supply chain performance has been a key element of competitive strategy to boost organizational productivity and profitability. In the United Kingdom (UK), a survey disclosed that approximately 40% of the UK’s gross domestic product (GDP) was consumed on supply chain related activities. Because of the extensive use of gross domestic product (GDP) on supply chain, it is important to work on UK based supply chain companies and to reveal various factors to enhance supply chain performance. Therefore, the primary objective of the current study is to investigate the combine effect of audit determinants and leadership styles to enhance supply chain performance in UK based companies. Data were collected from audit department employees and other managerial employees who are closely related to supply chain activities. After analyzing the data through Smart PLS 3, it was found that audit and leadership styles played important contribution in supply chain performance. Moreover, top management and employee commitment to change maintained significant influence to enhance positive effect on audit and leadership. This study is much significant for UK supply chain companies to enhance supply chain performance.

The presence of small and medium-sized enterprises (SMEs) in Indonesia will contribute to the movement of the Indonesian economy, so its growth is an essential part that must be considered by the government. The goal of this study was to explore the role of innovative capabilities in improving the performance of Indonesian SMEs. A variable approach to social capital, entrepreneurial leadership, innovation ability and SME efficiency was used in this research. The research included a sample of 352 small and medium-sized enterprises in Pekanbaru, Indonesia, consisting of 19 medium-sized enterprises and 333 small enterprises out of a total population of 2887 small and medium-sized enterprises (the sampling methodology used was chance sampling and simple random sampling methods). The findings show that social capital does not explicitly have a substantial impact on the business performance of SMEs in Pekanbaru, but if it is mediated by creative capacities, social capital indirectly plays a role in improving the performance of SMEs. Entrepreneurial leadership has a big influence on SMEs.

Differential evolution (DE) is an effective and powerful approach and it has been widely used in different environments. However, the performance of DE is sensitive to the choice of control parameters. Thus, to obtain optimal performance, time-consuming parameter tuning is necessary. Backtracking Search Optimization Algorithm (BSA) is a new evolutionary algorithm (EA) for solving real-valued numerical optimization problems. An ensemble algorithm called E-BSADE is proposed which incorporates concepts from DE and BSA. The performance of E-BSADE is evaluated on several benchmark functions and is compared with basic DE, BSA and conventional DE mutation strategy. Also the performance results are compared with state of the art PSO variant.

During the past few years, there have been tremendous attempts among various companies to implement the principles of supply chain management to increase their capabilities. Reduction in supply chain cost is an important element to support competitive advantage. However, to manage the cost of supply chain, managing target and order costs is essential. Reduction in both target cost and order cost is crucial to maintain reasonable supply chain cost, which directly influences the competitive advantage. Thus, the primary objective of this study is to support competitive advantage by the help of integration between target cost and order cost. To achieve this, quantitative research technique was adopted based on a survey technique and 300 questionnaires were distributed among the managerial employees of supply chain companies in Iraq. While analyzing the data through Smart PLS 3, it was revealed that any reduction in target cost and order cost could decrease the overall supply chain cost and this helps to sustain competitive advantage. Therefore, supply chain cost plays the mediating role to enhance competitive advantage through integration of the target cost and the order cost. Finally, this study is beneficial for supply chain companies to enhance competitive advantage through reduction in supply chain cost.
