Engineers designing machinery and structures to be fatigue resistant can gain useful insights about design and material properties by reviewing the literature. In this way, we can avoid costly research, but in the case of complex loading phenomena and the interaction of components, we must carry out such research. Fatigue strength calculations are less accurate than simple static calculations. The wear of link chains is concentrated in three areas, depending on the installation location and function of the individual links, namely: in the joints (the points of contact between two links), on the outer surfaces of the arches and on the outer surfaces of the straight sections of the links. During operation, chains are particularly vulnerable to wear through abrasion, corrosion and fatigue. These ageing factors, which act with varying intensity depending on the properties of the deposit, determine the service life of the chain, unless other unforeseen damage occurs, e.g. \"hard\" blockage of the chain. In many cases, users are guided by their own subjective criteria for assessing the technical condition of chains, which does not always lead to fully rational decisions regarding the continued use of used chains. To date, there have been no attempts to transfer the results of chain fatigue tests to behaviour of real objects. This paper presents issues related to mining chain fatigue testing. The test results presented are for both new and used chains. The experimental tests conducted at GIG made it possible to solve the problem of applying fatigue test results in industrial practice.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"31 1","pages":"78 - 85"},"PeriodicalIF":1.5,"publicationDate":"2023-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43305733","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}

The study examined the relationship between social capital, human capital, access to resources, and digital transformation of startups in Vietnam. The study used Partial Least Squares - Structural Equation Modelling (PLS-SEM) with a sample size of 230 startups managers. The results show that there are positive and statistically significant relationships between social capital, human capital, access to resources, and digital transformation. The results also reveal the partial mediating roles of access to resources and human capital in the relationship between social capital and digital transformation. The results proposed some managerial implications for startups managers in building relationship networks with stakeholders such as government agencies and business partners (customers, competitors, suppliers, and providers of digital platform services). Through managers' social capital, accessible resources and the improvement of human capital have accelerated digital transformation for startups to escape the crisis of the COVID-19 pandemic. Finally, the study presented some limitations and directions for further research.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"31 1","pages":"33 - 42"},"PeriodicalIF":1.5,"publicationDate":"2023-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44218071","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 paper analyzes relevant literature and proposes a systemic customer-centric knowledge-based production value chain (KPVC) to leverage distinctive core competencies (DCCs) and create sustainable competitive advantage (SCA) in manufacturing contexts. The paper introduces an integrative customer-centric KPVC model that enables companies to respond to environmental drivers, leverage DCCs, and create SCA. It adopts an exploratory approach to developing a unified and inherently interdisciplinary model based on a review of relevant scholarly literature. The KPVC integrated model comprises production value chain (PVC), knowledge management (KM) processes, and business process re-engineering (BPR) enabling activities. A successful move to KPVC requires a fully integrated and automated system allowing firms to define, track, and manage their work processes. Effective KPVC is a principal approach for leveraging DCCs in the quest for achieving SCA in today’s competitive business world and generating better values for customers and companies.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"31 1","pages":"27 - 32"},"PeriodicalIF":1.5,"publicationDate":"2023-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49218030","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}

Most of the existing alternative fuels by themselves cannot be considered as ready-to-use motor fuels. One of the ways to solve this problem is to use their mixtures with commercial fuels in certain ratios. This work deals with the development and research of the main characteristics of the mixer for obtaining mixed fuels based on diesel fuel and soybean oil, as well as the results of the study of the physical and operational properties of the obtained mixtures of different volume ratios of diesel fuel and soybean oil. The process of obtaining a mixed alternative fuel based on diesel fuel and soybean oil was implemented on a developed installation consisting of a mixer, the design of which is protected by a patent of Ukraine, and a gear pump. The study of the characteristics of the mixer as part of the installation showed that at a temperature of the components of the alternative fuel of 20°С, with a loss of full pressure on the mixer Δр ≈ (60-65) kPa, the volume consumption of soybean oil reached 10.7.10-6 m3/s. The time of preparation of the fuel mixture in the amount of 195 liters with a content of soybean oil of 10% ranged from 30 to 33 minutes. As research has shown, mixing soybean oil with diesel fuel in the amount of 5-50% vol. provides an improvement in viscosity-temperature properties and makes it possible to use such mixtures in diesel engines without changes in the design of the power supply system and regulation of fuel equipment, which characterizes soybean oil as a promising additive to diesel fuels to improve their technical and operational performance.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"141 5","pages":"71 - 77"},"PeriodicalIF":1.5,"publicationDate":"2023-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41255673","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}
