Purpose: In this study, the grey data envelopment analysis approach and the Malmquist productivity index were used to measure the efficiency and productivity of companies in the Tehran Stock Exchange cement industry. Methodology: First, we identify the appropriate financial ratios for measuring efficiency. Then, we calculate these ratios for each financial year as grey numbers (intervals). In the next step, these ratios are divided into two groups of input and output variables under research variables. Finally, the efficiency and productivity of the studied companies for the two fiscal years, 2018 and 2019, were determined using CCR and BCC models. Its components have been estimated.
Findings: The results of this study provide a suitable framework for using uncertain information (grey) to replace definite information and thus allow more realistic results to be estimated about the performance of companies. Findings: The results of this study provide a suitable framework for using uncertain information (grey) to replace definite information and thus allow more realistic results to be estimated about the performance of companies. Originality/Value: This study uses the Malmquist-Grey Productivity Index to provide a framework for comparing productivity changes over time. This index measures the ratio of the measured efficiencies of a production unit in two different periods.

Purpose: Although more than four decades have passed since the issue of telecommuting became a new method for organizing work and workforce, not many scientific and academic studies have been done in this field in our country. However, in recent years, the telecommuting plan has been on the government's agenda, and many government agencies and institutions have been required to implement government directives on telecommuting. The presence of crises such as the outbreak of COVID-19 has also added to the importance of this issue in recent years. Methodology: In this research, the data of teleworkers in the central headquarters of the Ministry of Industry, Mines and Trade were collected through a survey method. Thus, by designing two questionnaires for employees and managers, different dimensions of the plan and the consequences of telecommuting in this ministry were examined from two perspectives of managers and employees. Findings: The results showed that information and communication technology is the main component of telecommuting, so it is almost impossible to implement this plan without its infrastructure. It should be noted that communication infrastructure is not limited to communication tools such as computers and communication lines such as high-speed Internet, and the possibility of access to the organization's internal automation system and employee work card is also part of it. Originality/Value: In this research, the implementation of a telecommuting project in the Ministry of Industry, Mines and Trade has been studied from the perspective of managers and employees, and the main challenges facing this project have been analyzed and based on this, suggestions for better implementation of this project in Government agencies provided.
