Unmanned Aerial Vehicles (UAVs) play a very important role in military and civilian activities. In this paper, the aim is to cover the borders of Iran using UAVs. For this purpose, two zero-one programming  models are presented. In the first model, our goal is to cover the borders of Iran at the minimum total time (the required time to prepare UAVs to start flying and the flight time of the UAVs). In this model, by minimizing the total time of UAVs for covering the borders, the costs appropriate to the flight of UAVs (such as the fuel costs of UAVs) are also reduced. In the second model, which is mostly used in emergencies and when a military attack occurs on the country's borders, the aim is to minimize the maximum required time to counter attacks and cover the entire country's borders. The efficiency of both models is shown by numerical examples.

Nowadays, manufacturing companies have been working based on people-oriented approach. Customersatisfaction is currently not only for external customers but also required for internal customers. In thiscontext, human resource is one of the most important resources to manage and vital for manufacturingcompanies in terms of customers, employees and managers. With this perception, The Human ResourceManagement (HRM) issue is emerged. HRM enables effective and efficient management of humanresources. Manufacturing companies considers that the existing abilities and qualification of itsemployees is insufficient for achieving their targets. The gap between desired level of capabilities andthe existing capabilities of the human recourses should be narrowed. Therefore talent management(TM) concept is introduced in order to deal with the gap and reveal the required personnel profile. TMraises institutional awareness and is a supportive tool for HRM. The TM contributes to remove wastesof the companies and supports self-improvement of its employees. In other words the TM is a key of success about exploring abilities. The aim of this study is to propose a model for investigating competencylevel of employees and utilizing this information in obtaining a yield in an optimal level from employees’emotional and intellectual capabilities, and experiences. The level of perception and job-ability match ofeach employee is different. . In this study, a fuzzy logic approach is proposed in order to deal withuncertainty and vagueness in assessment of TM.
