“…A digital shadow (image) should be understood as a set of data about an object obtained simultaneously using special technologies [9]. There is still some confusion in the literature regarding the distinction between the concepts of digital twin and digital shadow, which are often identified the same [11,12]. However, the main difference between digital twin and digital model (image or shadow) is the use of the best available technologies to reflect the dynamics of the physical twin through the associated data system, which ensures convergence between the physical and virtual space, as well as gives the ability to manage physical twin through the digital one [5].…”

The paper is aimed at revealing the potential of digital twin concept use in relation to mining companies' assets management. The key advantages of digital twin implementation in different areas of mining production have been summarized. Improved operation efficiency, production safety and informed decision-making process are among the top ones. The paper presents the conceptual model of digital twin of a deposit, which reflects both its structure and functioning mechanism. The idea of digital mineral asset underpins it in conjunction with tools of historical and real-time data collection, storage and analysis. The key issues of economic evaluation of mineral deposit digital twin are addressed.

“…The approaches can be categorized into conceptual approaches and methodological approaches, whereby the conceptual category can be further subdivided into technical and organizational concepts. The technical concepts primarily focus on the realization of a digital shadow or a twin for individual production processes [23,[32][33][34][35][36][37][38]. A common deficit among these is their lack of detailed guidance for practical implementation.…”

The value stream method, a key tool in industry to analyze and visualize value streams in production, aims to holistically optimize process steps, reduce waste, and achieve continuous material flow. However, this method primarily relies on data from a single on-site inspection, which is subjective and represents just a snapshot of the process. This limitation can lead to uncertainty and potentially incorrect decisions, especially in industries producing customer-specific products. The increasing digitization in production offers a solution to this limitation by supporting the method through data provision. The concept of the digital shadow emerges as a key tool that systematically captures, processes, and integrates necessary data into a model to enhance traditional value stream mapping. This addresses the method’s shortcomings, especially in heterogeneous IT landscapes and complex value streams. To effectively implement the digital shadow this study identifies concepts of digital shadows and their key components and evaluates them for their relevance in industrial environments using an expert study. Based on the results, a design model is defined. This model entails guidelines to support companies with the practical implementation of the digital shadow of a value stream. Lastly, the model is evaluated on a realistic value stream in a learning factory.

“…The task of this data model is to ensure the correct flow of data and information. It provides the linkage between the virtual layer and respective use cases of the VSMM [23,32,37]. The use cases arising from VSMM are configured in specific sub models and use the central data model.…”

The Value Stream Method (VSM) is widely used in manufacturing to analyze and redesign value streams. The aim is to improve processes, reduce waste and create a thorough product flow. Despite having many benefits, VSM also comes with disadvantages regarding modern dynamic production environments. It fails to meet the requirement of providing reliable information for a realistic Value Stream Design (VSD) followed by targeted improvement activities. As a result, the VSM is usually subject to uncertainty and relies on expert knowledge. Digitalization, on the other hand, is leading to an increasing availability of production data. The use of data has the potential to support the VSM with targeted data preparation. In this regard, the concept of Digital Twin (DT) offers the capability of providing the required database to systematically collect and condense this data. This paper provides a framework for the Digital Value Stream Twin (DVST). In addition, requirements for the implementation of a DVST in practice will be elaborated.
