Due to the complexity of aerospace industry products, their development requires the use of different design teams, numerous scientific specialties and extensive resources. Therefore, companies need to refer to the resources hidden in external companies to improve performance due to their limited resources. Based on this, companies cooperate with each other. Entering a partnership requires the ability to work together so that the partnership is not compromised. Therefore, the problem facing companies is understanding, recognizing the capabilities of joint efforts and its impact on joint performance. This study examines several capabilities that enable companies to use them as a tool to combine knowledge and expertise in a partnership and increase their performance. In the context of the dynamic capability perspective, "resource sharing capability", "joint planning capability", "problem solving capability and joint performance appraisal" and "joint venture cultural capability" have been identified as collaborate capabilities and then using structural equation modeling of effects They have studied the performance of joint product design and development in the country's aerospace industry. The results show that the stated capabilities have a positive effect on the design performance and development of the joint product.

The increasing growth of space achievements, which is the result of the NPD and the increase in the level of exploitation of its findings, has made the space sector an effective role in economic development and increasing GDP and the space industry is also subject to this category. Structural actions in space have created problems in the field of rockets and satellites as a concern in space over the past decade. A review of the research background reveals the impact of three levels of industry, firm and process on NPD. In this research, the problematic situation in the space industry was identified, through interviews and documentation, and the results were validated by creating a focus group. 34 factors related to NPD at this level were identified by reviewing the research background. The extent of their impact on achieving the country's space goals was assessed by the SAW method of MADM and five factors affecting NPD were selected. Then, the interaction of factors was evaluated with Micmac software. Relationships between factors were prioritized by structural analysis of factors. It was found that the factor of structure and organizational relationships at the level of the space industry has a direct impact on the time of new product entry into the market. Therefore, the rulers of the space sector should pay special attention to them. Finally, priorities and suggestions for improving decisions for NPD were presented.

The present study aims to analyze the discourse of management and policy-making in the field of electricity in the country to study and analyze the text of 100 interviews, lectures, statements and quotations conducted in this regard in the years after the revolution; Based on the theory of Laclau and Moff discourse,it focuses on specific themes and their elaboration Thus, first the main themes and axes of policymakers' discourse were extracted and then it was determined which themes have a special position and how they are placed in that discourse according to other themes. The main themes and axes of the dominant discourse entitled "Development based on the abundance of fossil resources in the country" are: "Sustainable electricity supply", "Self-sufficiency and self-reliance in the electricity industry", "Economic supply of electricity" and "Poverty alleviation and justice", have been elaborated around the central slab of "fossil fuel-based development". Analyzing the discourse of policymakers showed that they see the issues of electricity supply in the context of the "fossil electricity discourse" which is at the heart of "fossil fuel development". In this way, all their actions become meaningful in the context of the fossil regime discourse, and this discourse has been able to marginalize other sub-discourses, whether modifying or opposing the use of this energy, restructuring the electricity, nuclear and renewable industries, and this discource masters its concepts and achieves hegemony.

The Aircraft Maintenance, Repair, and Overhaul (MRO) has always played a key role in the aviation industry which is responsible for restoring aircraft to flight conditions based on a set of technical instructions and implementation of repair processes. According to researches, the most important reasons why airlines choose MRO centers to provide services are quality, turnaround time (TAT), and cost, respectively. In this research paper, the application of lean, its principles and techniques, and in particular the study of its compatibility and effectiveness in order to reduce TAT in the aircraft repair and overhaul industry has been considered. Accordingly, at the beginning and after the comprehensive review and analysis of the literature, the subject of a comprehensive list of principles of lean production has been studied and the indicators have been considered according to the characteristics of the aircraft repair and overhaul industry. Then, based on the obtained indicators, a questionnaire was prepared, and based on it, more than 25 hours of interviews with experts, including deputies, managers, and experts of the aircraft repair and overhaul industry in the case study were conducted. Based on the Yin analysis method (2003), the data of the questionnaire were analyzed and evaluated in order to identify the influential factors of service time during the aircraft maintenance check. Based on the research findings, the existence of defects in some areas, such as the lack of inventory management and alternative planning for serviceable components have created significant effects in increasing the service time of aircraft.

The purpose of this study was to develop a model for strategic agility in relation to sustainable production boom in automotive industry. The present study seeks to increase the flexibility of industries and enhance accountability in a turbulent environment. The research method is qualitative and is based on the theory of grand theory. Semi-structured interviews were used to collect data. Data analysis was performed by Strauss and Corbin method. The sampling was done by theoretical sampling and using purposeful-judgment techniques and snowball. The study involved 14 experts in the automotive industry. The results of the analysis of the interviews resulted in an open, axial, and selective coding process to provide a model of strategic agility based on data theorization of the foundation that included 6 categories and 17 concepts. According to the strategic agility model, the factors affecting the strategic agility in the automotive industry are "intra-organizational factors", "manufacturing factors", "individual factors". Contextual conditions such as "economic factors", "political factors", "stakeholders", intervening conditions such as "legal requirements", "management features", "infrastructure formulation" as well as strategies "utilizing new technology", "Structural change", "Strategic change", "Infrastructure reform", "Supply chain change" and "Human resource agility" and the implications of strategic agility in the automotive industry include "intra-organizational outcomes" and "extracurricular outcomes".

The automotive industry is one of the drivers of economic growth and a symbol of the country's industrial development due to its strong backward linkage with other industries and services. Problems arising from government interventions in this industry and the need to improve its resilience to external consequences, optimize market regulation and reduce demand for speculation, remove multilateral monopolies among producers, balance profit in the production chain, full familiarity of consumers By its very nature, the establishment of coordination between small and medium-sized parts manufacturing enterprises and the promotion of technological capabilities of manufacturers in line with global developments requires a review and reform of the regulatory structure of this industry. The results of evaluating the regulatory structure of the automotive industry through library, field and institutional mapping studies (institution-function matrix) indicate that, firstly, the scattered distribution of regulatory tools among 23 different institutions leads to policy incoherence in this It has become an industry, and secondly, issues such as design and R&D, branding, attracting foreign investment and international participation (production), the depth of domestic manufacturing in parts manufacturing and the transfer of technical knowledge to the interior (import), consumer rights and Competitiveness (pricing), spare parts market and how to supply sales agents (supply), marketing and giving consumers the right to choose (consumption) in the regulatory structure of this industry has not received much attention. Hence, in the end, solutions to reform the regulatory structure of this industry are presented.
