Macroergonomics Factors Generating Work Time Losses in Interpretation of Grey Systems Theory

Purpose – The purpose of this paper is to discuss how tacit and explicit knowledge determine grey knowledge and how these are stimulated through interactions within networks, forming the grey hybrid intelligent systems (HISs). The feedback processes and mechanisms between internal and external knowledge determine the apparition of grey knowledge into an intelligent system (IS). The extension of ISs is determined by the ubiquity of the internet but, in our framework, the grey knowledge flows assure the viability and effectiveness of these systems. Design/methodology/approach – Some characteristics of the Hybrid Intelligent Knowledge Systems are put forward along with a series of models of hybrid computational intelligence architectures. More, relevant examples from the literature related to the hybrid systems architectures are presented, underlying their main advantages and disadvantages. Findings – Due to the lack of a common framework it remains often difficult to compare the various HISs conceptually and evaluate their performance comparatively. Different applications in different areas are needed for establishing the best combinations between models that are designed using grey, fuzzy, neural network, genetic, evolutionist and other methods. But all these systems are knowledge dependent, the main flow that is used in all parts of every kind of system being the knowledge. Grey knowledge is an important part of the real systems and the study of its proprieties using the methods and techniques of grey system theory remains an important direction of the researches. Originality/value – The paper discusses the differences among the three types of knowledge and how they and the grey systems theory can be used in different hybrid architectures.

Decision Making Criteria

PurposeThis paper is a part of the application trend of the development of the grey systems theory. The purpose of this paper is to present the use of the GDM model in the diagnosis of the occurrence of crises in family businesses. The issue of the occurrence of conflicts and crises in family businesses is one of the most important and common in management science in Poland.Design/methodology/approachIn the paper using the GDM model (in which the weights of the criteria were determined using the modified Thurstone method), the authors presented a way to diagnose the occurrence of crises in family businesses for a sample of Polish family businesses using, among others, a questionnaire-based survey.FindingsAs a result of the conducted research, it turned out that in eight surveyed businesses no symptoms of conflicts were diagnosed. In three businesses, the symptoms of conflicts were diagnosed, but they did not threaten their existence. In the case of four businesses, the symptoms of crisis that threaten their existence were diagnosed and immediate remedial action was recommended to them.Originality/valueThe authors are of the opinion that the presented research results may be a reason for the validity of using the GDM model in the diagnosis of crises in family businesses. At the same time, it is recommended to undertake further research on,inter alia, conflict fields in family businesses, or on the use of the modified Thurstone method as a part of determining the validity of decision-making criteria in GDM models.
