Abstract: 

 Software- set of mathematical methods, and algorithms of information processing, which used in creating the computerized management system (CMS). Initial data for the design of CMS software system is a list of functional task includes the task and function of computer aid design (CAD), computerized enterprise management system, and others. Material and methods: The method was most widely used. Most algorithms in computerized management systems are computerized (solving problem modeling, control, accounting, planning, and others). Many of them implement various mathematical methods (management solution, and others).  In this study, two algorithms were used to evaluate mathematical expression, after which the result was compared in both cases. Results:  As looking, this paper shows the created algorithm which needs for the development of the program support for computerized management system.   Keywords:
