This article discusses the company's production performance evaluation system, which is based on the strategic objectives of a production company. Key performance indicators for shaping the company's manufacturing operations are formed into a matrix that describes the level of strategic planning in production performance. Production performance evaluation system is a resultant tracking model that aids the company to react quickly to changes in business environment, while maintaining security of supply, quality and profitability of production operations.

The hypothesis of this work is that information systems development is possible with lower TCO (Total Cost of Ownership), if OLAP (On-Line Analytical Processing) model is developed together with OLTP (On-Line Transaction Processing) model and if those two models are in relation to each other. That kind of combined model makes possible to develop virtual data warehouse solution, with automatically generated ETL (Extract, Transform, Load) business logic. The result of this work is the customized development method of information systems, where are joined together OLAP and OLTP conceptions to create the combined data model. Composed method is base for the virtual data warehouse to provide same kind of functionality like classic and static OLAP dimensional database does.

The hypothesis of this work is that information systems development is possible with lower TCO (Total Cost of Ownership), if OLAP (On-Line Analytical Processing) data model is developed together with OLTP (On-Line Transaction Processing) data model and if those two models are in relation to each other. By using Model-Driven (MDA) development methods, that kind of combined model makes possible to deploy virtual data warehouse solution with automatically generated ETL (Extract, Transform, Load) business logic. The result of this work is the database meta-model, which stores OLAP and OLTP data models and relations between them. Composed method is base for the virtual data warehouse to provide same kind of functionality like classic and static OLAP dimensional database does. ©2010 IEEE.

Globalization and higher competition sets companies a demand to search for possibilities how to improve performance and competitiveness. Main resources influencing company's performance are human resources and their skills and competences and machine tools with their technological possibilities. Human resources with their skills and competences and machine tools with their technological possibilities form technological capability of workplace. In this article, role of workplace as one key parameter in formation of company's performance and competitiveness is analysed.

The main purpose of the current paper is to introduce information systems development concepts and chosen technologies for E-Manufacturing solutions. The main goal is to achieve interoperable systems with high efficiency and reliability by using MDA (Model Driven Architecture) and SOA (Service Oriented Architecture) technologies. Current scope focuses to MDA development where custom application is automatically deployed into Alfresco environment by using Eclipse modeler with Topcased layer together with SIDE-Labs application generator. The MDA toolset will be evolved to generate ERP implementation model with custom functionality for MS Dynamics NAV.
