The purpose of this study is formation of tools for forecasting the economic security of the enterprise by modeling methods when changing investment support. The relevance of this study is due to the need to solve the problem of modernization management system of the enterprise by implementing the project management of economic security of the enterprise in the implementation of investment programs.The variant of model offered economic security of the enterprise. This model involves the implementation of the process of adaptive management, based on the definition of safe limits of longterm growth of the enterprise. It has established that the ratio of self-organization processes and managerial influences depends on the value of the self-organization coefficient. The calculated value of adaptive potential on the basis of the indicator of self-organization as the dynamic indicator of maintenance of perspective growth of the enterprise on the allocated purposes has offered. This indicator can serve as a criterion for assessing the effectiveness of the management system of the enterprise in relation to the project management of economic security of the enterprise in the implementation of investment programs of key goals of long-term growth of the enterprise.

Workflow management system is playing more and more significant role in business process management (BPM) and office automation (OA) of enterprises[. It can improve the efficiency and manageability of an enterprises daily teamwork, control as well as coordinate the processes[. Traditionally, it is not easy for the workflow modeling method to describe the complex business process clearly and intuitively. In this paper we improved the role based workflow model, and proposed a workflow modeling method based on multi-role playing. It is possible to make the modeling easier and simpler when we come to the complex business process modeling problems. Finally, an example of a B/S based Enterprise Financial Reimbursement Management System (EFRMS) is demonstrated to prove the convenience and feasibility about the method mentioned.

Nowadays, identification and neural methods are used more and more often in modeling IT forecasting systems in addition to analytical methods. Six characteristic models used to forecast the Day-Ahead Market system functioning as a transaction management system at the Polish Power Exchange (POLPX) and the Nord Pool Spot market have been selected for comparative analysis. The research was preceded by a detailed discussion of modern criteria used to assess the quality of model fitting to the system, namely: effectiveness, efficiency, and robustness. In the literature, there are two main groups of system modeling methods, namely time series modeling methods and identification modeling methods, including neural modeling methods. Modeling usually results in such models as parametric models and artificial neural networks learned neural models of the Day-Ahead Market, as well as time series models, among others. In the comparative analysis, special attention was paid to the accuracy of the obtained models concerning the system. It has been pointed out that the studied solutions used to measure the accuracy of modeling criteria such as accuracy of fit or efficiency, and did not use the modeling efficiency, which is very important in IT forecasting systems for such large markets as the Day-Ahead Market of POLPX. The search for the best market models, including identification models of the Day-Ahead Market operation that can be used in electricity price forecasting is a very important issue both from the point of view of algorithmic solutions and economical solutions.
