Identifying, analyzing and using the most appropriate and efficient methods for planning business processes is a key to success for every enterprise.

Our paper are two objectives: to identify the most proper methods used for planning and applying for the same case study. We are looking to demonstrate the methodology of using some software tools and compare the obtained results. The application domain will be the planning of production processes but these methods can be extended to the service processes.

The methodology is represented by the mathematical models and software applications in this fields, such as Simplex model theory, Solver Excel tools, WinQSE application, linear programming with PL.exe.

The results of the research have a high applicability level and can be extended in other business fields too.


The implementation of up-to-date technologies in the accounting system of modern entities is a topical subject, by the desire of enterprises to align themselves with the current of international globalization but also by the requirements imposed by the science and practice to join the accounting main issues in the field. The accounting technique evolved with the technological innovations, related to each evolutionary period of the human society. The paper aims to identifying the factors that influenced the whole process of the development of information technologies in the financial-accounting field; identifying the main issues related to the technological interaction in accounting and, in this context, identifying the tools and technological supports in the evolution of the accounting technique, from the empirical forms of accounting to the present day, in the age of globalization, amid the continuous need for normalization and standardization of accounting procedures, especially applicable to the consolidation of financial results.

Nowadays, the most used digital technology in computerized accounting and management is Cloud-Computing ERP solutions, a form of digital accounting that will represent the critical mass of accounting information system in the near future, and this paper will present and discuss such solutions.


A mathematical model for the water ow on a hill covered by variable distributed vegetation is proposed in this article. The model takes into account the variation of the geometrical properties of the terrain surface, but it assumes that the surface exhibits large curvature radius. After describing some theoretical properties for this model, we introduce a simplified model and a well-balanced numerical approximation scheme for it. Some mathematical properties with physical relevance are discussed and finally, some numerical results are presented.
