Purpose: One has worked out an application that allows to analyze the efficiency of technological process in aspect of nonmaterial values and has used neural networks to verify particle indicators of quality of a process operation. Indicators appointment makes it possible to evaluate the process efficiency, which can constitute an optimization basis of particular operation. Design/methodology/ approach: The created model made it possible to analyze the chosen technological processes for the sake of efficiency criteria, which describe the relationships: operation - material, operation - machine, operation - man, operation - technological parameters. Findings: In order to automate the process, to determine the efficiency of technological operation (KiX) and possibly to optimize it, one has applied one of artificial intelligence tools - neural networks. Practical implications: Application of neural networks allows to determine the value of technological efficiency of an operation. (KiX) without the necessity of detailed analysis as well of the whole process as of the particular operation. It makes it also possible to optimize operation efficiency by means of checking value of operation efficiency in the case of change in value of particular partial efficiency indicators. Originality/value: Method of computer application makes it possible to point out the studied indicators and asses finally the process efficiency in order to plan optimization of particular operation.

Purpose: What determines the correcttness of industrial company's functiioning on the market is technological process. In order to improve it continuously the priority should be technology, technology management and controlling. Design/methodology/approach: by means of this model one can analyzy the choosen technological processes for the sake of efficiency criteria. They describe following relationships: operation-material, operation-machine, operation-man, operation-technological parameters. Findings: This analisis shows hypothetical technological processes on production of typical pieces for machines. One has also taken into account nonmaterials parameters of technological process. They are resulting from applied sampels and projecting of the technological process. Practical implications: Thanks to the created aplication we can analyze efficiency of technological process in aspect of nonmaterial values. By the use of neural networks we can verify particle indicators of process operation quality, evaluate the process efficiency, which can constitute the optimization basis of particular operation. Originality/value: Data effecting from this analisis allowed to optimize the technological process. They estimate influence of the analyzed parameters on the whole process and optimizethe conducting of any process.

Purpose: Technological process is a basic determinant of correctness of industrial company's functioning on the market. In this connection they should treat with the priority all activities connected with technology, technology management and controlling, that is with their continuous improvement. Design/methodology/approach: The created model made it possible to analyze the chosen technological processes for the sake of efficiency criteria, which describe the relationships: operation - material, operation - machine, operation - man, operation - technological parameters. Findings: in this thesis - conducted analysis includes hypothetical technological processes of producing typical machine pieces. Within their scope also the nonmaterial parameters of technological process have been taken into account, which resulted from arts of applied samples and projecting of the technological process. Practical implications: One has worked out an application that allows to analyze the efficiency of technological process in aspect of nonmaterial values and has used neural nets to verify particle indicators of quality of a process operation. Indicators appointment makes it possible to evaluate the process efficiency, which can constitute an optimization basis of particular operation. Originality/value: As a result of this analysis gained data enabled to optimize the technological process by estimating influence of the analyzed parameters on the whole of process and optimization conducting of any process.

Purpose: Technological process is a basic determinant of correctness of industrial company’s functioning on the market. In this connection they should treat with the priority all activities connected with technology, technology management and controlling, that is with their continuous improvement. Design/methodology/approach: The basis for preparing the process analysis model are the indicators of fragmentary and technological efficiency, as well as standardized parameters of the technological process depending on the applied treatment. Findings: Thanks to the appropriate indicators it is possible to identify operations which need to be verified. Although interdisciplinary process control is very complex, it offers objective assessment. The assessment should include the influence of individual parameters on the process and enable good choice of the optimisation type. Practical implications: The process analysis with the use of immaterial parameters based on different types of processing and the design of the technological process involved assessment of technological process efficiency with the use of indicators of operational efficiency. Originality/value: Creating computer applications for calculating individual indicators, as well as final efficiency assessment used for planning optimisation of individual operations.
