Conceptual Modelling in Operational Simulation of Logistics
Logistics problems involve a large number of complexities, which makes the development of models challenging. While computer simulation models are developed for addressing complexities, it is essential to ensure that the necessary operational behaviours are captured, and that the architecture of the model is suitable to represent them. The early stage of simulation modelling, known as conceptual modelling (CM), is thus dependent on successfully extracting tacit operational knowledge and avoiding misunderstanding between the client (customer of the model) and simulation analyst.

Criteria for the Adoption of Sustainable Maintenance Practice
The evolution from traditional industrial maintenance to sustainable maintenance (SM) is pivotal within the existing industrial ecosystem. It represents a critical transition towards integrating sustainability principles into maintenance practices including environmental, social and economic outcomes. Increasingly focused on SM, the importance of understanding the impact of environmental initiatives and sustainability indicators becomes a focal point. However, the paradigm shift of SM is lagging in the industrial ecosystem. Although it marked a growing interest in the academic community, the lack of empirical studies and practical implications of adopting SM has been reported. Based on the Bayesian analysis, and the bibliometric and thematic analyses, the role of digital technologies in enhancing SM practices highlights the potential pathways for easier transition and applicability of sustainability-related maintenance practices.

Barriers to Textile Recycling in India
Post-consumer wastes from the textile industry are generally landfilled or incinerated. The dumping of large amounts of textile waste has resulted in severe environmental problems. Advancements in technologies have called for textile recycling; however, the level of embracement made by the textile industry towards textile recycling is hampered by myriad factors. Sstudy indicates a lack of successful recycling business models, poor demand for recycled textiles goods, recycled products may not replace new products, lack of support for waste management in the industry, and absence of tax relief and rewarding policies as the top five barriers to textile waste recycling. This insight could help influence the decision of future policymakers in the field. Another aspect of the issue of pollution in the textile industry is the recent trend of fast fashion and the enormous amount of waste produced by overconsumption. The Sustainability Development Goal (SDG) 12 which is to ensure responsible production and consumption plays a key role in this sector.

Integration of SysML and Virtual Reality Environment
In recent years, Model Based Systems Engineering (MBSE) has continued to develop as a standard for designing, managing, and maintaining increasingly complex systems. Unlike the document centric approach, MBSE puts the model at the heart of system design. Among the various MBSE language development efforts, “Systems Modeling Language (SysML)”, is the most anticipated and broadly utilized in the research and in industrial practice. SysML originated from Unified Modeling Language (UML) and follows the Object-Oriented Systems Engineering Method (OOSEM). SysML diagrams help users create various systems engineering artifacts, including requirements, use cases, operational concepts, system architecture, system behaviors, and parametric analyses of a system model. In the early days of implementation, MBSE languages, including SysML, typically relied on static viewpoints and limited simulation support to depict and analyze a system model. Due the continuous improvement efforts and new implementation approaches by researchers and organizations, SysML has advanced vastly to encompass dynamic viewpoints, in-situ simulation and enable integration with external modeling and simulation (M&S) tools. Virtual Reality (VR) has emerged as a user interactive and immersive visualization technology and can depict reality in a virtual environment at different levels of fidelity. VR can play a crucial role in developing dynamic and interactive viewpoints to improve the MBSE approach.

Achieving Sustainability in Solar Energy Firms in Turkey
Lean principles and sustainability are considered important terms in business. Solar firms are witnessing great competition to fulfill energy requirements, suffering from a huge amount of waste, negatively affecting the sustainability dimensions. Thus, the aim of the study is to build a framework for solar energy firms to achieve sustainability through adopting lean principles, which will help to fix many problems as waste and costs. The method included reviewing the literature to explore the founding of the relation between the two terms, and using a questionnaire that was directed to the responsible people in Turkish solar energy firms. The results of the survey were analyzed to: (1) Find out what the responsible people think about the two terms lean and sustainability; (2) Measure the probable relationship between lean principles and sustainability dimensions by applying a linear regression test; (3) Use the results of point number two to build the framework. The result showed there was a high level of relative importance about the two terms from the point of view of managers and experts in solar firms. In addition, the study found a relationship between adopting pull and flow principles of lean, and achieving economic and social dimensions of sustainability, this finding is represented in a framework.
