1. INTRODUCTION

Economic, Environmental and Ergonomic pillars have found their way to the list of political priorities of national economics. The concept of virtual programming of the real technological workplace being solved is significant also from the point of teaching development strategy at STU MTF. It allows to design the technology as well as it permits the definition of the basic principles of the technological process control system. The virtual methods imported in the beginning phase of the development is highly effective due to more 3E vital and acceptable aspects.

2. STRATEGIC ASPECTS OF HCS 3E MODEL IN A VIRTUAL TECHNOLOGICAL WORKPLACE

The concept virtual model of a technological workplace is designed in the phase of the project. It allows to design the technology in real as well as it permits the definition of the basic principles of the technological process control system. The implementation of virtual methods leads to immediate decisions on effectivity from various aspects. There are three acceptable aspects (3E) of sustainable development:

1.) Environmental aspects--each of the technologies carry an environmental burden which is also reflected to the economic aspects because of the operational measures that have to be followed. The advantage of the proposed virtual technology application means that it is not necessary to produce the model of a technological device, nor it is necessary to create the real technological workplace. By the production of the aforementioned devices, the environmental burden is minimized (Cernecky, 2005).

2.) Economic aspects--there are few of them. They can be divided into partial groups and subgroups. The most important aspects that have to be in the optimization of such a technology that are taken into consideration are the investment costs(the amount of finances related to the specific virtual equipment purchase) and operation costs (technological devices, electricity consumption and other related costs) which can influence also the decision making in a new technology purchase.

3.) Ergonomic aspects of virtual technologies--working environment, lighting, noise, protective clothing necessary for the operation of such a technology, etc. (Barborak, 2007) At present the optimization is used and applied in different information systems oriented on conventional technologies whereas the possibilities of virtual technologies are neglected. The necessity of computer aided tool that will take these aspects into account is vital in national as well as in European research. The issue is vital also for the top European companies involved in the subsupply of reputated car factories.

3. SUPERIORITY IN VIRTUAL PROGRAMMING

By the project investigation and implementation the following aspects from the view of basic principles of a new paradigm will be fullfilled:

1.) Certain deviation from the principles of traditional rational pradigm followed by the majority of organizations and schools in the past and still followed by several traditional ones.

2.) In contrast with the rational opinion, the supporters of the current paradigm of technological workplaces think, that the organization effectiveness is needed not only internally but externally as well.

3.) All faculty structures (organizational structure, study programmes, organizational control, university control, etc.) are the organization reflections to the external changes.

4.) Current trend of teaching technical subjects has to be researched as a socioeconomic and environmental system (HCS 3E model).

Designed virtual/real workplace reflects as well as accepts the aforementioned three most important aspects of sustainable development/environmental, economic and ergonomic aspects.

4. ESSENTIAL INVESTIGATION PROCESS

In the first phase the project concept will be elaborated. The whole scope of works will be defined, by what method will be investigated.

1.) To carry out collective investigators' brainstorming to identify the key terms and the hierarchy of partial tasks/goals and their intrefaces.

2.) To carry out analysis for partial tasks/goals in the selected universities and companies in the Slovak Republic.

3.) To generalize partial analysis conclusions.

4.) To propose methods for partial tasks/goals.

--a general model of robotic workplace,

--method to investigate the control system of a laboratory robot,

--method of the effectivity evaluation of the environment-friendly oriented workplace at universities and companies,

--possibilities of using the exact methods for teaching at universities,

--interface for the user program transfer and control.

In the second phase of the project investigation:

--to verify related methods of individual tasks/goals at the Institute laboratory equipment,

--to carry out final corrections of the related methods,

--to generalize the knowledge into final proposals of individual systems of control programming and interface,

--to process the synthetic final research report.

Upon project completion, the programming itself will be carried out with the programming of all the needed functions so that there is no duplication and the application is capable to simulate the industrial robot as well as the entire robotic workplace.

The final phase will be devoted to testing. After testing the application the virtual application will be transformed into the real robotic workplace.

5. ANIMATION APPLICATION AND INTERFACE

Animation as a significant part of the application illusatrates the current state of all units and parts of the robotic workplace. It is impressive not only by the manual control but also by the data processing.

The animation will be carried out by the means of object oriented Microsoft visual C+ with the use of graphic library Open GL, both providing wide possibilities of the use of a large number of orders and functions.

Library Open GL is compatible with Linux operation system and represents a standard in 3D graphics. Iterface has to be compatible with the data processing generated from the virtual scene, then transformed into the real environment of a robotic workplace (Ozvoldova et al., 2007).

6. PROPOSAL OF THE BOUNDARY APPLICATION

In the phase of the proposal of the boundary application, it is essential to define the boundary between the application itself and the application user. The ergonomics of the boundary application is an important point, i.e. the simpler the control the better. Another important condition of an application control overview is represented by the smallest possible number of control units for the user.

[FIGURE 1 OMITTED]

In the simulation application of the virtual robotic workplace, there will be many control units but they will be arranged and implemented in such a way so that they are user friendly.

Application control. It is necessary so that the application control is unified as a whole and that there is one control unit per function. Individual control units will be called by names or abbreviations and the control will be assisted by a helper.

7. CONCLUSIONS

Results are considering the new trends related to the environmental aspects and operational economics of the workplace. The necessary training of new managers in the field is focused prevailingly on ergonomics and workplace control of a new type. The aforementioned results are succesfully being carried out in SKODA AUTO, a.s. Mlada Boleslav. The HCS Model 3E reflecting sustainable development (micro-solutions of macro-problems) of the virtual reality in economics, environmentalism and ergonomics as a vital environmental prerequisite is fully accepted. The abovementioned issues are highly topical and often also controversial once they carry both environmental and economic aspects (related to "externalisation and internalisation costs") (Hatiar & Sakal 2007).

On one hand, the various ways of environmental protection influence the economic structure, on the other hand, they create conditions for future survival of man. At the same time they are closely related to the environmental impact caused by the technologies in mechanical engineering. Therefore, the gradual implementation of new virtual technologies is suitable as soon as in the phase of the production and technological processes begins. Now when the energy sources are limited, the mentioned technologies can win a reasonable share on the market.

The contribution was elaborated within the research project VEGA No. 1/0368/08 The use of artificial intelligence in the control of flexible production systems and the research project VEGA MS SR No. 1/3523/06 Research of new technical and technological principles of wood concentration together with the KEGA project No. 3/3111/05 The creation of virtual robotic laboratory for supporing teaching the subject Robots and manipulators in a newly accredited study programme.

The paper is also aimed at contributing to the vision of the Agenda 21 and Lisbon Strategy in the field of industrial pillars of sustainable development strategy at the STU MTF research and pedagogical processes.
