The aim of this study is to propose a comprehensive performance evaluation model with emphasis on service performance metrics in the service-product supply chain rather than the production supply chain in the home appliance industry and using neural-fuzzy networks for performance evaluation. The present study is typically a descriptive-exploratory research with survey approach in which, data analysis has been conducted using quantitative method and exploratory and confirmatory factor analysis. For the purpose of this study, a sample of 58 home appliance companies has been selected and Smart-PLS, SPSS and Matlab software have been used for data analysis. Findings indicated 10 main constructs and 29 performance criteria obtained for evaluating the performance of service supply chain and fuzzy neural networks of several home appliance companies. Introduction: Based on predictions, services are a key component of the growth of the global economy in future (Arnold et al. 2011). Acording to Jane and Kumar (2012), services play a critical role in a supply chain. Also, according to Wang et al. (2015), a "product" or "service" must exist in each supply chain which is produced by the upstream sectors and delivered to downstream. Recently due to increasing customer expectations, companies’ competition has been replaced by the supply chains competition and as a result, competition has been increased in the simultaneous supply of products and services. This has led to challenges in integrating companies and in coordinating the materials, information and financial flow that were previously overlooked. Accordingly, a new managerial philosophy has been developed known as Product-Service Supply Chain (PSSC) (Stanley & Wisner, 2002). This study seeks to develop a performance evaluation model for the product-service supply chain in the home appliance industry, which is finally solved using Adaptive Neuro-Fuzzy Inference System (ANFIS). Design/Approach: In this paper, performance evaluation constructs and criteria of service supply chain are identified by reviewing the literature and exploratory and confirmatory factor analysis and then, the performance evaluation of service supply chains in Iran's home appliance industry has been performed using these constructs, criteria and ANFIS. Findings and Discussion: Based on the findings, ten main extracted constructs can be suggested for the performance evaluation of the supply chain. They include "Operational Performance (OP)", "Strategic Performance (SP)", "Financial Performance (FP)", "Performance of Information and Communication Technology (PICT)", “ Return Performance” (REP), “ Risk Performance (RIP)” , “ Logistic Performance (LP)” , “ Market Performance (MP)” , “ Internal Structure Performance (PIS)” and “ Growth and Innovation Performance (PGI)” , among which, the Strategic Performance (SP) and Return Performance (REP) are the most important and the least important constructs, respectively. Conclusions Based on the findings, the following practical recommendations are suggested to the companies:  Enhancing the demand forecasts performance and utilizing more appropriate methods and software to improve forecasts in demand and order management areas.  Improving the return management status by increased attention and more investment in return management processes.  Effective investment in service development management to enhance the R&D services performance.  Utilizing risk management approaches and methods to identify and take preventive actions on the risks in the companies’ service supply chain.

This study aims to design an electronic supply chain management model to achieve a world-class home appliance industry.

In line with the research findings, suggestions are made for improving the studied industry to reach the world-class in the future.

Objective In today's dynamic environment, gaining an edge over competitors is essential for survival and growth in a competitive market. Survival and growth in such an environment are possible through innovation. Outstanding and innovative products, advanced technology, and innovation in marketing will not have an impact on the company's success if they do not create a significant competitive advantage. Open innovation recommends that companies give as much importance to external ideas as they do to internal ideas to access different markets, identify market opportunities, and create a competitive advantage for the company. This research aims to identify and prioritize the factors of open innovation in gaining a competitive advantage in the home appliance industry.   Methodology The present study is considered to be applied research and falls into the category of descriptive-analytical research. The research process of this study consists of four main phases. In the first phase, using library methods, the effective factors of open innovation were extracted from the research background. In the second phase, the extracted factors and sub-factors from the research literature were presented to the experts of the home appliance industry, and using the Fuzzy Delphi method, 10 categories of factors and 45 important sub-factors were identified and classified. Then, considering the selected factors and sub-factors, a three-level hierarchical model was obtained, where the first level is the ranking of the factors and sub-factors affecting open innovation in gaining competitive advantage. At the second level, the factors affecting open innovation and at the third level, the sub-factors related to each factor are placed. In the third phase, based on the hierarchical model of the research, a pairwise comparison table was formed and provided to the experts in the form of a pairwise comparison questionnaire. Then, to extract the weights of the factors and sub-factors, the Fuzzy Analytic Hierarchy Process method was used, which is one of the common multi-criteria decision-making methods. In the fourth phase, the factors and sub-factors of open innovation in gaining competitive advantage in the home appliance industry were prioritized.   Findings The research findings indicated that, according to experts in the home appliance industry, innovative marketing, strategic, creativity development, and cultural factors are the most important among the 10 identified factors. Among the sub-factors of innovative marketing, marketing variables and customer orientation are important. Among the strategic sub-factors, strategic resource acquisition and employees' attitudes towards open innovation are significant. Among the creativity development sub-factors, brainstorming and the SCAMPER method are crucial, and among the cultural sub-factors, goal alignment and organizational learning are the most important sub-factors.   Conclusion The results indicate that innovative marketing is chosen as the most important factor of open innovation in gaining a competitive advantage, according to industry experts. Innovative marketing in the home appliance industry can lead to the development of new and innovative products in this industry. It also leads to increased competitiveness among home appliance brands and manufacturers, ultimately improving the user experience and increasing demand for innovative products, thereby creating a competitive advantage in this industry. Innovative marketing variables, including innovative products, innovative promotions, innovative pricing, and innovative product distribution, have a significant impact on gaining a competitive advantage in home appliance companies.

The objective of the present study is to develop a model for green research and development (R&D) in the path towards sustainable development within the home appliance industry. This research is applied in nature and descriptive-survey in terms of data collection method. Initially, through a literature review, 30 factors were identified as indicators for green development and formulation and were categorized into five dimensions: green management, product performance and stakeholders, internal environment management, green innovation, and energy and resource consumption management. To screen and validate the factors extracted from the literature, the fuzzy Delphi method was used by surveying 15 selected experts through purposive sampling, which led to the identification of 25 components across the five dimensions. Subsequently, the importance of each criterion and sub-criterion was determined based on the Analytic Network Process (ANP) method, using a pairwise comparison questionnaire with Super Decisions software. The reliability of the tool was confirmed with a consistency ratio below 0. 1. Based on the findings, green management, with a weight of (0. 261), has the highest priority among the other criteria. Similarly, the product performance and stakeholders criterion (0. 220) ranks second, internal environment management (0. 202) ranks third, green innovation with a weight of (0. 191) ranks fourth, and energy and resource consumption management with a weight of (0. 124) ranks fifth. According to this ranking, it can be concluded that factors related to green management hold the greatest importance in green R&D indicators.

The purpose of this study was to investigate the social resilience of economic organizations against institutional anomie at the level of non-governmental economic organizations (Iranian home appliance industry Association) with an institutional analysis approach. The research was conducted from 1399 to 1400. The type of research method is qualitative and the type of data analysis method is inductive thematic analysis. The data collection technique was episodic interview. The research population includes all members of the association, 21 of whom were purposefully selected. Findings showed the foundations of institutional anomie can be traced at both macro and micro levels. At the macro level, the change of fundamental structures, the establishment of society in a state of transition, and the emergence of new spirits in Iranians led to the creation of the mentioned anomie. At the micro level, the failure to achieve common values and ideals paved the way for anomie, and the inconsistency of actors' cultural tools and rules to achieve a common goal, the quest for transformation, exacerbated that anomie. Contrasting to Merton's theory of anomie, in this study it was found that, it is possible for actors to act simultaneously in the form of two or more of these cultural patterns. Given the simultaneous commitment of the members of that association to the model of "adaptation and conformity" plus "innovation and innovation", the model of "transformational adaptation" can be added to the models mentioned by Merton that Indicates creative resilience.
