SYSTEMIC ANALYSIS OF MODELS OF DYNAMIC SYSTEMS OF SHAFT MACHINING IN ELASTICDEFORMABLE CONDITION

The paper presents methodology of developing models of dynamic systems of machining shafts in the elastic-deformable condition. The specifics of dynamic system (DS) identification concerning straight turning and straight and plunge grinding of low-rigidity shafts is presented. The specifics of the process of lowrigidity elements machining is taken into account through the introduction of suitable equations of constraint reflecting additional elastic strain in one of the equations describing the control force effect. Systemic analysis of the developed models is performed, and their hierarchical structure is given.

SAFE MANUAL HANDLING IN INDUSTRIAL PRODUCTION

This section provides the technical information for using the revised lifting equation to evaluate a variety of two-handed manual lifting tasks. Definitions, restrictions/limitations, and data requirements for the revised lifting equation are also provided.

THE IMPACT OF ERP SYSTEM ON ECONOMIC SITUATION OF ENTERPRISE: CASE STUDY

The implementation of ERP system is performed to integrate business processes, efficient charge of company resources and give important data for decision support. Implementing of ERP system is expensive and time consuming. Therefore a great number of research activities are focused on key success factors of ERP implementations but only few deals with long term impact of ERP system on enterprise performance. In the article the relationship between implementation of ERP and values of important economic ratios of enterprises is analyzed. The analysis is a base for presented evaluation methodology of ERP system from economic point of view. As an example, an enterprise is taken into
account that implemented ERP system in 2001. The illustrative examples are given.

METHODOLOGY FOR ANALYSIS OF FUNCTIONING AND IMPROVEMENT OF PRODUCTION SYSTEMS BASING ON COMPUTER SIMULATION

Modelling and simulation with optimization finds wide usage in the improvement of production systems. Production systems are so complex, that without computer it is not possible to realize detailed analysis of processes taking place in them. The methodology for realization of simulation projects with ARENA for improving production processes is presented in this paper.

COMPUTER VISION BASED UGV STEERING

This report deals with a computer vision system for unmanned ground vehicle. The concentrated aspects include the comparison between image and model and intrinsic and extrinsing parameters of camera.
