Opis:
Purpose: The aim of this paper is to develop a functional model for the synthesis of nanostructures of the given quality level, which will allow to effectively control the process of nanopatterning on the surface of semiconductors with tunable properties. Design/methodology/approach: The paper uses the IDEF0 methodology, which focuses on the functional design of the system under study and describes all the necessary processes with an accuracy sufficient for an unambiguous modelling of the system's activity. Based on this methodology, we have developed a functional model for the synthesis of nanostructures of the given quality level and tested its effectiveness through practice. Findings: The paper introduces a functional model for the synthesis of nanostructures on the surface of the given quality level semiconductors and identifies the main factors affecting the quality of nanostructures as well as the mechanisms for controlling the formation of porous layers with tunable properties. Using the example of etching single-crystal indium phosphide electrochemically in a hydrochloric acid solution, we demonstrate that the application of the suggested model provides a means of forming nanostructures with tunable properties, assessing the quality level of the nanostructures obtained and bringing the parameters in line with the reference indicators at a qualitatively new level. Research limitations/implications: Functional modelling using the IDEF0 methodology is widely used when process control is required. In this study it has been applied to control the synthesis of nanostructures of the given quality level on the surface of semiconductors. However, these studies require continuation, namely, the establishment of correlations between the technological and resource factors of synthesis and the acquired properties of nanostructures. Practical implications: This study has a significant practical effect. Firstly, it shows that functional modelling can reduce the time required to form large batches of the given quality level nanostructures. This has made it possible to substantiate the choice of the initial semiconductor parameters and nanostructure synthesis modes in industrial production from the theoretical and empirical perspective. Secondly, the presented methodology can be applied to control the synthesis of other nanostructures with desired properties and to reduce the expenses required when resources are depleted and the cost of raw materials is high. Originality/value: This paper is the first to apply the IDEF0 methodology to control the given quality nanostructure synthesis. This paper will be of value to engineers who are engaged in the synthesis of nanostructures, to researchers and scientists as well as to students studying nanotechnology.

Opis:
Increasing globalization requires the search for new solutions to form and manage enterprises. One of a possible approaches is creating business groups with different types of cooperation. The analysis of European Union law and Polish law carried out in the article speaks in favor of creating business groups with the principle of vertical cooperation. Achieving the strategic goals of the individual members of the group requires a flexible and adequate model of cooperation. One such solution is developing business process models. The main goal of the paper is presents principles of creating such models for both individual and cooperating companies using the IDEF methodology.

Opis:
The article discusses issues related with process modeling. Process modeling is supposed to help to describe, analyze and document processes within the discussed organization. Processes can be modeled with use various tools, some as simple as a sheet of paper and a pen, some sophisticated as specialized notations. It is crucial that the selected method (language) of modeling is under-standable to all people participating in the process. Currently, there are over 70 modeling languages in use. The choice of a modeling language depends on peculiarity of a process as well as the deter-mined objective. The present work provides a list of the most commonly used languages and a des-cription of some of them (e.g. BPMN notation, SwimLane method, UML).

Opis:
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.
