  In today’s competitive market, companies must work closely with their customers and suppliers if they want to survive and improve their own performance and to provide a better response to market forces. In a typical supply chain, information flow is more important than the other two involved flows including material flow and cash flow. It can be lead to enhance organizational knowledge. The main purpose of the research, is to identify, analyse and improve the performance of an assembly line using simulation techniques. Many factors, such as setup time, operating time, failure rate, repair rate, and production rate, can cause data to be non-stationary. Therefor, in order to analyse such complicated systems it is necessary to apply simulation techniques. The most important properties of an assembly line including bottlenecks, cycle time, buffers capacities, and the number of finished products in a given time period are investigated in the research. After data gathering, and building an appropriate simulation model, the simulation experiments were done with Enterprise Dynamic software. The simulation model is implemented and tested against real-world data and is demenostrated by a numerical example. Then, the bottlenecks and performance measures including throughput time and waiting time are identified and analysed in order to develop a new scenario in which opportunities for improvements are presented. The results show significant improvements in terms of reducing waiting time and increasing efficiencies. Manuscript profile

  These days, organizations environment has become more competitive. According to business researchers, achieving a competitive position for the company is possible only by the proper business model. A successful business model indicates a better option so that it can offer greater value to a distinct group of customers and bring greater benefits to the company. At the start of a business, failure to identify an appropriate business model, leads to the failure of organizations to achieving its goals. Despite the importance of this issue, there is no standard for the definitions and components of business models. Hence, in this study, definitions and components of business models are discussed, according to the different approaches in modeling business models. However, merely having a good business model at the inception of a company is not enough; what is more important is utilizing and maintaining a proper business model over the life of the institution.The power of a business model is such that it can be a powerful tool for analyzing, testing, and evaluating organization's strategic options. Therefore, an organization business model evaluation as a strategic decision-making process will never stop and can be a basis for continuous improvement of the business. Business model evaluation differs according to the levels and units of analysis. In this study,by reviewing the different studies, the most important criteria and methods of business model evaluation has been proposed.Business models are the representation of businesses at a specific time. Rapid technological, economical, cultural and political changes lead to a more complex organizations environmentand dynamic business evolution. This causes instability of business models. Therefore, they change by the development of businesses. Hence, business model innovation has become one of the most important issues in management science. This concept has been studied in the final part of this study. Manuscript profile

  Environmental problems with economic and social inequalities caused by the industrial revolution led to intensifying the rise of movements and ideas in the second half of the 20th century to achieve a balanced development in different fields, which can be referred to as sustainable development theory. Achieving the goals of sustainable development in the field of architecture requires attention to all environmental, economic, and social aspects. Studies have shown that sustainable architecture, especially later-related movements, which utilize modern technologies in design and construction fields, are more suited to such goals. In this regard, computer-based design technologies, as effective instruments, played a significant role in achieving sustainability goals. This research investigates the amount of the effects of building information modeling (BIM) applications in different stages of the design process on achieving sustainability goals. The research method is descriptive-analytic. So indicators related to the use of BIM in sustainability achievement were collected through the library sources and case studies that contain sustainable buildings, which were designed using BIM applications. Then, by performing a hierarchical analysis based on the criteria derived from theoretical foundations, the authors concluded that the major BIM effects in achieving sustainability are due to the possibility of using dynamic analysis in the early stages of the design process, particularly the conceptual design stage as well as the establishment of effective interactions between engineers and other stakeholders.

  With the advent of the Internet and Coronavirus outbreak, e-learning environments and web-based learning, there has been a considerable growth and development in recent months and years, but this type of education faces many challenges. The most important of these challenges are the use of learning patterns, modeling student behavior, evaluating student support and feedback, curriculum planning, sequencing, and teacher support. One way to deal with these challenges is to find effective factors on accepting and improving the quality of education in learning systems, discovering rules and educational patterns, and using them to predict future outcomes. The aim of this study is to identify factors affecting the adoption of e-learning, based on the technology acceptance model. For this purpose, studies in this area were investigated. Variables such as computer self-efficacy, quality of content, system support, user interface design, technology tools and computer anxiety as factors affecting adoption of e-learning system were extracted. According to them, the conceptual model of this research was developed. In order to evaluate the model and relationships between variables, a questionnaire was provided to the users of e-learning system in Qazvin University of Medical Sciences. The results of data analysis by using structural equation modeling have approved authenticity of all hypotheses excluding the impact of technology tools on the acceptance of e-learning system. Findings of this research can help educational managers of university and related instructors with this system to encourage students making optimum use of the system by providing the necessary fields for the imposition of effective factors.
