The apparel industry is among the income-generating and entrepreneurial ones in the global and national arena. The purpose of this paper is to explain the challenges facing Iran in the production and distribution of clothing and to provide policy packages to solve them. In this research, data were collected through the literature review and semi-directed in-depth interviews and investigated using qualitative content analysis. 191 propositions were classified into 31 sub-categories and rendered to form 6 main categories. The main categories are "resource-based view", "government advocation", "technology and machinery", "effective supply chain", "branding" and "design and fashion". Then, to finalize and validate the challenges and policy packages, focus groups were formed. Among the important challenges are insufficient government intervention and support to play a regulatory role, inefficient supply chain and infrastructure, and weakness in fashion design and presentation. The proposed policy packages can be mentioned as fighting against smuggling, developing a platform for the integration of the apparel chain, creating a comprehensive brand in the field of designing and direct supply of clothing, developing financing tools (capital market, bonds), developing the export of knowledge-based products and services, development of the scale and market of knowledge-based products and services, the application of augmented reality technology in online sales, the creation and development of accelerators and specialized innovation centers, the first production of cost-effective and economical machines and parts, the creation of clothing production industrial centers, and elimination of tax discrimination throughout the apparel.

Explaining the quality of employee-organization relations in unplanned changes resulting from an event such as an epidemic in the workplace is an important concern. With this aim, this article presents a model on the effect of transparent communication within the organization on the quality of employee-organization relations. From the point of view of use, purpose and time, this research is applied, exploratory and a cross-sectional study, and in general, it is a quantitative research with a survey and gathers data by a questionnaire tool that is in the form of a matrix and with scalable closed questions resulting from literature review and interviews. The statistical population includes the employees of one of the subordinate organizations of the Ministry of Defense and Armed Forces Support, and the sample size, using the available method, was 95 people. Structural equation modeling and SmartPLS software have been used to test the hypothesis. The findings of the research include that clear communication within the organization directly and through the mediating variables of "control exposure strategies" and "perceived uncertainty" affects the employee-organization relationship in unplanned changes. It can be concluded that transparent communication methods provide the possibility for employees to participate in the decision-making process and receive sufficient and reliable information during unplanned change, to equip themselves with the tools to face such changes. Also, clear communication practices help manage unplanned changes by reducing uncertainty.

In today's era, the supply chain has taken a large share of human activities. In the field of SCM, to achieve better performance and focus on core capabilities, supplier performance monitoring is very important. On the one hand, the issue of globalization and transcontinental outsourcing, and on the other hand, the issue of viability has imposed high importance to choosing the right approach to the supplier based on the strategic importance and supply risk. Therefore, the success of organizations in the global competition environment is highly dependent on formulating the type of relationship with suppliers, including affiliation, cooperation, long-term rewards, and a multi-source approach. In this paper, by using adaptive neuro-fuzzy inference, the performance of the SC has been evaluated based on the components of reliability, responsiveness, agility, costs and efficiency of asset management in the case study of " Zanjan Zinc Refinery Company". The output of examining the indicators related to each component in this method will lead to predicting the performance of the supplier and formulating a strategy to achieve the desired situation. In addition, the comparison of clustering models showed that the fuzzy mean clustering method with the number of 4 clusters has the lowest prediction error. The results of this research make it possible to measure the performance of the SC from different perspectives of the SCOR model. One can also provide information that helps the system expert to analyze the gap between the expected and the current performance level in terms of the mentioned components.

The use of electric buses has a great effect on reducing traffic and air pollution. The purpose of this article was to examine the challenges facing the country to produce and benefit from this product and solutions to solve these challenges. In this research, data was collected through documentary studies and in-depth semi-guided interviews and analyzed through qualitative content analysis. The target community was the experts of electric bus manufacturing companies and related institutions. The number of 72 propositions were categorized into 10 sub-categories and finally 6 main categories, the main categories of which were empowerment, cost, technological cooperation and cultural alignment. Then, action was taken to form a focus group and the extracted challenges and solutions were validated and finalized. Among the important challenges are the dependence on foreign electric propulsion, the unaffordability of bus operations, the high price of electric buses, the infrastructure for conducting some specialized tests to obtain the standard, and the lack of culture for using this new product. Some important solutions include the domestication of electric motors and accessories with government support from domestic companies, the creation of a joint supply chain for bus manufacturing companies, the preparation of a business model based on public-private partnership, and the implementation of Article 12 of the law on removing barriers to production, cultural measures and promotion based on new product and technology requirements, design of night charging system for bus batteries and design of electric base buses

One of the unrealistic assumptions of the economical production quantity model is the perfect quality the goods produced. To this end, following the previous attempts, in this paper it is assumed to have destructive inspections and existence of imperfect and rejected items after rework. In developed models, the new EPQ model has been calculated under 3 circumstances: 1- Imperfect items are not counted into the inventory after inspection, 2- The mentioned items are kept in the stock up to the end of production period within each cycle in EPQ model, 3- Aforementioned items are kept in stock up to the end of cycle. Moreover, we found out that if we use the traditional amounts instead of new ones, the total cost per unit time will increase with the same order. Finally, as sum of the fractions of imperfect and reworkable items ascend the EPQ and total cost per unit time will increase. A numerical example is applied to address the reliability of the results.

Regarding the importance of CoPS in providing the organization with technological capability and the differences existing between these systems and mass products, it is essential to develop a model to collaborate on CoPS R&D. Exploitation of the capabilities of the network of collaborators is a desirable option due to inability of the organization in providing the resources comprising finance, human, facilities and expertise. Reviewing the literature on CoPS and technological collaboration incorporating the kind and motivations of collaborators and organizational forms of collaboration and interviewing 18 experts of the organization, a model was developed based on TRL approach and fuzzy cognitive mapping tool. Considering the model developed, the steps of project is classified into 3 categories: Green(able to be collaborated in network), Yellow (able to be collaborated on condition) and red (unable to be collaborated). The role of the members of the network and the strategy of collaborating with them is specified as follows: R&D contract with universities and consulting agents, Educational acquisition with faculty members, outsourcing the projects intended as military service compensation, and R&D contract or research funding with knowledge-based institutions. On the other hand, the position of technology developing and designing centers is specified employing the national innovation system as an upper hand document. Validity of model is proven by checklist of good theories.

Network of collaborators is the most important approach of organizations in CoPS R&D projects conduction as completing such projects requires specific resources and is beyond the capabilities of a single organization. Obviously the capabilities of the network of collaborators have a significant role in mentioned collaboration. So in this paper fundamental indicator of those capabilities were firstly specified by literature review. Secondly final indicators were selected using survey of experts of a CoPS producing company. Thirdly these indicators were classified in components by expert survey and using SEM in LISREL software. These components encompass collaborators competency (incorporating knowledge and skillfulness, keeping up to date, complying to standards and financial ability), task performance capability (incorporating project quality, time and responsibility during and after project completion) and adaptability (incorporating accordance to values, time and flexibility in deliverables). The results of hypothesis tests illustrate that competency has a significant and positive impact on task performance and the latter has a similar impact on adaptability but there is no direct and significant correlation between competency and adaptability while there exists an indirect one.

Regarding the cooperation with superior extra organizational resource suppliers required to the development of CoPS, the strategic outsourcing of the CoPS R&D projects is among the solutions to acquire the resources related to the equipment, knowledge, human resource, and finance. Following the literature review and the explorative interviews, in the present paper, using a Fuzzy Delphi method a survey of 35 experts was conducted in Iranian Organization of Aviation Industries. By studying this case, 21 related indices were derived. Given the reciprocal cause and effect among the indices, the DEMATEL technique was employed to demonstrate these relations. The results of the relations were used to prioritize the indices by ANP . The final prioritization urges that the indices “cost reduction”, “the organization competence in preserving the results and the IPR of the projects”, and “the flexibility of the organization for outsourcing” are of the greatest importance respectively

Among the most important unrealistic assumptions of EOQ model is the perfect quality of items received in stock. Trying to overcome this constraint and making the mentioned model get closer to real circumstances, this paper considers destructive inspections and the existence of imperfect and rejected items after reworking. EOQ is determined under three following conditions: 1- rejecting the imperfect and reworkable items after the inspection 2-keeping the aforementioned items until the end of the inspection period, and 3- keeping these items until the end of the cycle. Results show that using the traditional model instead of the modified new model will lead to increased costs. In other words, with an increase in total proportions of imperfect and reworkable items, EOQ and the total cost per unit of time will increase. A numerical example is solved to evaluate the results.
