For many years, Poka-Yoke (PY) has been used as one of the means to overcome challenges that can affect errors and defects in process. It is a widely accepted concept-a way of thinking, which undoubtedly contributed to significant results in a struggle against the occurrence of errors in various work processes. However, although PY seems to be well understood in theory, there are a large number of scientific papers and books that still seek to clarify and redefine PY, in order to finally implement its application at full capacity. Many authors, as it seems, want to emphasize inconsistencies in current theoretical and practical experiences. This claim is supported by the fact that over 50 similar and different PY definitions have been found in literature. It seems that most researchers do not sufficiently perceive generally accepted attitudes in the field of PY, as well as differences and inconsistencies in some of them. Due to a sense of confusion during the process design stage, an effort to predict locations of possible sources of error is a direct consequence of the diffuse knowledge in the field, which imposes the need to change that state. This paper summarizes the latest studies and definitions in the field of PY applications, in order to propose a comprehensive and generally acceptable definition of PY. In order to find what is common to the most important attitudes in the field of PY, a systematic literature review has been undertaken, with the goal to identify the areas of disagreement, to recognize any gaps that exist and outline personal experiences and attitudes in the field. The novel approach to the types of PY presented in this paper should provide a solid foundation for the creation and development of PY model and a systematic approach to the application of PY in production and service systems. Finally, some conclusions and prospective future research directions are presented. Highlights • Detailed systematic literature review on Poka-Yoke (PY) is presented. • More than 50 examples and case studies on PY are reviewed. • A novel approach to types of PY is proposed. • Examples of PY devices are created and discussed.

Nowadays many companies are applying the lean philosophy and value stream mapping (VSM) tool to eliminate and reduce losses and show possible places for further implementation of the lean concept. Since the system change takes place as a consequence, it is very useful to confirm the future system design performance before the actual implementation. This paper presents an application of VSM and computer simulation in a company for manufacturing and distribution of heating, cooling and neutral equipment for catering and trade industry. To improve the quotation creation process, the product configuration system is introduced. The performance of the new system design was confirmed using the discrete event simulation. Simulation results show several performance improvements. Conducted simulation experiments emphasize the better performance of new system design in terms of the accepted quotations, resource utilization, delivery time, work in process, non-value-added time and number of required operators.
