The output capacity of college testing center study

The process of testing students in a designated unit of the university (Testing Center) has a stochastic nature. An experience shows that when individual tests are appointed in conjunction with class schedules, a significant part of the testing center equipment is not used, because the actual duration of an individual test is much less than the period given to it. The study of probability patterns of the individual testing process aims to determine such modes of operation of the Testing Center, in which both the values of downtime and the possible number of students waiting for testing would be within reasonable limits. To solve this problem, first, a statistical analysis was carried out of the data collected earlier for individual tests. Secondly, a model of the mass service system, reflecting the most significant features of the process under study was developed. Next, a simulation of the processes taking into account the peculiarities of the duration of individual testing and the incoming flow of applications of the different structure was performed. The conclusion about the preference of analytical modeling over simulation modeling is obtained due to the simplicity of its calculation procedures and qualitatively similar results. Taking into account possible irregularity in the incoming flow of applications, on the contrary, can significantly affect the functioning of the Testing Center. The fore-casted peculiarities of the work of the Testing Center in stress mode were described.
