The first part of the article concentrates on the cumulative functions concept. There is a description from the manufacturer’s perspective of product functions followed by the customer’s perspective of product functions. Combining these perspectives leads to the creation of the new cumulative functions concept. The second part of the article concentrates on preliminary product design, where the cumulative functions are used. It consists of three main parts: Morphological analysis, Crude design structures and Evaluation of product design variants.","PeriodicalId":135905,"journal":{"name":"Acta Mechanica Slovaca","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131507510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike the optimization in which an attempt is made to model a problem directly, analytically or through modelling using heuristic, the simulation tracks another, i.e. intuitive approach. The development of information technology has created the need to apply a comprehensive system of technical data management in industrial practice. It was necessary to increase the efficiency of information sharing within the value-added chain of the company on specific projects. The aim of this paper is to create a model of production disposition with material flow simulation in TX Plant Simulation software environment for verifying the maximal potential capacity of production.","PeriodicalId":135905,"journal":{"name":"Acta Mechanica Slovaca","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121173977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is also closely connected with achieving a certain level of performance that is carefully monitored through individual indicators. Financial performance indicators (e.g. relative indicators, absolute indicators, etc.) are particularly monitored. Non-financial performance indicators are also very important, however, only little attention is paid to them in enterprises. Some non-financial performance indicators can be expressed numerically, but in units other they can reflect factors which significantly contribute to the overall company performance and cannot be figured out in monetary terms. Corporate culture is an important factor affecting non-financial indicators. Therefore, research carried out in frame of dissertation thesis at the STU Faculty of Materials Science and Technology in Trnava in 2018, was focused on the impact of corporate culture on performance of large industrial enterprises in the Slovak Republic. The research was also part of the VEGA 1/0348/17 project implementation: “The Impact of the Coexistence of Different Generations of Employees on the Sustainable Performance of Organisations”. There are presented statistically verified and appropriate evaluated research results in the article.","PeriodicalId":135905,"journal":{"name":"Acta Mechanica Slovaca","volume":"CE-30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126543523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organizational development is used as an overall framework for permanent organizational change and is related to change management and innovation implementation. Organizational development is a purposeful process of change that aims to create an organizational environment for a prosperous knowledge organization. Therefore, it is important to look at the organization from different perspectives that we can visualize in the form of organization models. Visualization of organizational models helps to determine what is possible and purposeful to change directly in the organization and what is no longer possible.
