In today's business environment enterprises are trying to establish reorganization changes in their work and organization. It is necessary to structure the existing business to understand all enterprise functions, and change them in order to achieve the main enterprise objectives. To stay competitive under new conditions the external and internal factors should be assessed before restructuring of existing practices. The goal of this paper is to show how to put into practice the process of transition from Small-sized enterprise to Medium-sized enterprise category. For this purpose the existing company data that is stored in the ERP system should be transformed into knowledge. In this paper we consider the conditional "Metal Service" enterprise that produces various metal constructions and plans to produce load lifting equipment (jib cranes, overhead cranes, and additional equipment for existing cranes) for manufacturing enterprises that produce heavy products. The manufacturing capacities of enterprise are defined based on IDEF0 functional model created for each type of product. The simulation results received from these models enables to analyse new production processes, to estimate production time and route for all type of unit and yearly product release. In addition, after the Systematic Layout Planning (SLP) methodology and Relationship Matrix (RM) was applied to simulation results it became possible to calculate new manufacturing area, facilities layout and to assess the new production capacities.

Nowadays an increasing number of enterprises realize the importance of competitiveness improvement through collaboration. It is obvious that the collaborative network is becoming an effective tool that enables small and medium sized enterprises (SMEs) to survive under the global crisis pressure. It enforces enterprises to focus resources and means on the main activities, and to rebuild the architecture for manufacturing system in effective ways. Therefore, we decided to continue working on research topic of collaborative manufacturing projects management. In this paper we introduce the novel framework for the further development of the existing collaborative network concept in which we combined multiple project management methodology and fractal model of collaborative network of enterprises. The proposed framework enables SME-s to use resources more efficiently, reduce manufacturing costs, rapidly respond to customer demand changes, increase the productivity, reduce total lead time of collaborative projects, improve the products quality, improve the practice of collaboration in multi-project management, improve stability, share the expensive costs and equipment, reduce inventory, raise the accuracy of the forecast, reduce the data entry time, and improve the performance of delivery. In this paper, we will present the project-based fractal collaborative network framework, multiple project management and fractal model framework. We will introduce our vision of information and communication processes in the novel collaborative network, tasks and relationships of collaborative enterprises project managers, external and internal relationships of project managers.
