Given that various operational methods can be considered for a system, applying changes to study the results and determine the best operational technique is costly and disrupts the system. Thus, to analyze and evaluate the outcomes of employing different operational methods, simulation is utilized. In this study, to improve the performance of a med...

An important method for ranking of decision making units (DMUs) in data envelopment analysis (DEA) is cross-efficiency method. This study proposes a secondary multi-objective model for calculating optimal weights with least dispersion. Firstly, these weights are placed in the smallest interval. Secondly, the cross-efficiency of each of the other un...

This research focuses on the role that Economic Policy Uncertainty (EPU) plays in creating adverse effects on the quality of financial information and the profitability of firms, with an emphasis on identifying the relationships and effects thereof on Audit Quality (AQ) and Financial Reporting Quality (FRQ) to achieve a proper understanding by fina...

The primary purpose of this research was to understand the importance of supply chain strategies in the field of supply chain risk management, emphasizing the effectiveness and efficiency of agile and lean strategies to create resilience and robustness in the supply chain. Data was collected from 392 supply chain experts working in Iran's automotiv...

Today, the role and importance of data as a valuable source and a key factor for the growth of various businesses and creating a competitive advantage in many markets is not hidden from anyone. The ever-increasing growth and development of data sets has led to their becoming larger and more complex in such a way that traditional databases are not a...

Identifying and eliminating throughput bottlenecks is a key tool to increase throughput and productivity in production systems. However, due to the complexity and dynamics of factory, eliminating throughput bottlenecks is considered a major challenge. Researchers have tried to develop tools to help identify and eliminate these bottlenecks. Historic...

The purpose of this research was to investigate the effect of emotional intelligence of employees on customer loyalty from the online platform with regard to the mediating role of relationship quality in the banks of Gilan province. The statistical population is all the customers and employees of banks who used the bank's online services in the per...

Identifying and removing throughput bottlenecks is a key tool for increasing throughput and productivity in production systems. However, in the real world, removing throughput bottlenecks is considered a major challenge. This is due to the complex and dynamic factory landscape, with several hundred machines at any given time. Academic researchers h...

Purpose: The providing a proposed model pair for ranking interval data and their application to evaluate and improve the performance of a service system using results of simulation Methodology: Mathematical techniques (data envelopment analysis) and computer simulation Findings: By presenting proposed models pair, we were able to improve the perf...

Various methods are applied in data envelopment analysis (DEA) in order to determine the efficiency of decision making units (DMUs), one of which is a model with weight restrictions. In this model, weight restrictions are considered depending on the importance of indices. However, data envelopment analysis can't distinguish among DEA efficient unit...

Obviously, data envelopment analysis has not discrimination power to distinguish between DEA efficient units. In this paper, is firstly determined efficiency score of decision making units under weight restrictions (WR) model. This weight restrictions point importance of indexes (inputs and outputs). Next are proposed two methods to rank. In first...

This article, aimed to evidence Hise and Szymanski's e-satisfaction model within Saderat Bank branches customers in Guilan. In this model, Convenience, Merchandising (product offering and product information), Site design, and financial security are the important factors in customer assessments of e-satisfaction. E-satisfaction can be defined as th...
