امروزه پاسخ تقاضا به عنوان عنصر مهم در قابلیت اطمینان شبکه هوشمند شناخته شده است. سیستم های مدیریت انرژی خانه های هوشمند که راه اندازی وسایل برقی را با توجه به ضرورت استفاده و کارایی در اولویت قرار میدهند، نقشی حیاتی در اثربخشی استراتژی های پاسخ تقاضا دارند. شفاف سازی جزئیات مصرف برق در قبوض با وجود فناوری های حسگر به نظارت بهینه استفاده از لوازم خانگی کمک می کند. در این تحقیق، یک مدل یادگیری ماشین بدون نظارت، برای خوشه بندی لوازم خانگی به منظور مدیریت قبوض برق بر اساس ویژگی های ذاتی آنها مطرح گردید، چرا که بر این اساس میتوان جزئیات مصرف به ازای هر خوشه از لوازم خانگی را در قبض مصرفی دوره لحاظ کرد و به دلیل وجود خوشه های محدود برای لوازم خانگی امکان مدیریت و نظارت بر مصرف برق امکان پذیر میگردد. لوازم خانگی با روش خوشه بندی سلسله مراتبی به سه خوشه طبقه بندی شدند. خوشه اول لوازمی است که به صلاحدید مشتری بلافاصله روشن شوند، خوشه دوم طبق برنامه زمانبندی روشن میشوند و استفاده از آنها میتواند به تعویق افتد و خوشه سوم لوازمی هستند که توسط تعداد محدودی از مشتریان ترجیح داده میشوند. ضریب silhouette بعنوان معیاری برای ارزیابی عملکرد مدل خوشه بندی سلسله مراتبی ایجاد شد، که مقدار 0.56رضایت بخشی مدل را نشان می دهد. بر اساس نتایج، مشخص شد که روش خوشه بندی پیشنهادی می تواند با انتخاب ویژگی های مناسب، انواع مختلف لوازم خانگی را بطور منطقی طبقه بندی کند، زیرا لوازم موجود در یک خوشه شبیه به یکدیگر هستند و می توانند به کاربران در درک عملکرد لوازم خانگی کمک کنند.کلید واژگان: شبکه هوشمند, سیستم مدیریت انرژی خانگی, پاسخ تقاضا, خوشه بندی سلسه مراتبیNowadays, demand response is recognized as an important element in the reliability of smart grid. Smart home energy management systems, which prioritize the start-up of electrical appliances according to the necessity of use and efficiency, play a vital role in the effectiveness of load response strategies in residential areas. Considering the sensor technologies, clarification on electricity consumption details helps to optimally monitor how the appliances are used. In this research, an unsupervised machine learning model was proposed for the clustering of home appliances to manage the bills of customers based on their inherent characteristics. Due to the small number of clusters, it becomes possible to manage electricity consumption. The hierarchical clustering method was used to classify appliances into three clusters. The first cluster is the appliances that are turned on at the discretion of the consumers immediately, the second cluster is the appliances that can be turned on according to the schedule and their usage can be postponed and the third cluster is appliances that are preferred by a limited number of consumers. The silhouette coefficient was developed as a measure of the hierarchical clustering model performance, where the average silhouette coefficient of 0.56 indicates the satisfaction of the model. Based on the results, it was found that the proposed clustering method can rationally classify different types of home appliances by selecting the appropriate characteristics since the appliances in a cluster are very similar to each other and can help users understand the operating conditions of the appliances.Keywords: Smart Grid, Home Energy Management System, Demand Response, Hierarchical Clustering

کلید واژگان: استراتژی فناوری اطلاعات, مرور سیستماتیک کیفی, بازمفهوم سازیOver fifty years have passed since the introduction of the information technology strategy. This concept has changed drastically due to variations in the basic concepts of strategy, both theoretically and practically. The present study is aimed to examine the historical process of the formation of this concept. Therefore, using the systematic review method and compendium content analysis, a comprehensive search was conducted on different databases. After refining the retrieved documents, they were classified into six categories: methodology of information systems, formal planning, IT strategic planning (including strategic alignment, searching and discovering IT opportunities in the domain of competitive advantage, IT portfolio management, and development of technology policy and architecture), IT capability development, IT micro strategy development and IT platform as a strategy. Then, by studying selected texts, conceptual codes were extracted in accordance with the problem question. The codes are categorized into different categories. Then, five concepts of IT strategy were identified based on basic theories related to each category: IT strategy as a plan, as supporting businesses, as a pattern, as a business transformer, and as a perspective. Results revealed that the two concepts of IT strategy as a plan and as supporting businesses are rarely studied nowadays. Few studies have focused on IT strategy as a pattern, including the experimental examination of the results of this concept in various organizational contexts and the investigation of dynamic capabilities. The concept of IT strategy as a business transformer focuses on the integration of business strategy.

International Journal of Research in Industrial Engineering, Volume:12 Issue: 3, Summer 2023, PP 306 -320The corporate landscape is highly affected by two market factors, namely digitalization and sustainability. These two driving forces have been the topic of several studies on how they change management methods, businesses, and society in general. However, the point that these two trends meet each other has been mostly neglected by research studies. Modern organizations and corporations are dealing with the adopting digital transformation issue as a new strategic paradigm. The present study attempts to elaborate on the relationship between digital transformation and sustainability. Therefore, through an in-depth review of the relevant literature, critical factors and their indicators were determined, and based on the proposed conceptual model, six hypotheses were developed. Then, a questionnaire was designed and distributed among 120 Iranian experts, managers, and consultants, and 97 complete questionnaires were returned. Reliability, Content Validity Ratio (CVR), and Content Validity Index (CVI) of the questionnaire were calculated, and the hypotheses were tested through Structural Equation Modeling (SEM) using SmartPLS Software. The results showed that digital transformation significantly affected an organization's sustainability aspects through operation, customer, business model, technology, workforce, and collaboration. Digital transformation and sustainability should constitute integral parts of organizational strategy. Considering that business practices affect the environment, society, and economy, digital transformation can influence the business sustainability. Digital technologies transform markets and create novel paradigms in the industry. In addition, they present new solutions to organizations to cope with sustainability issues. Due to this importance for organizations as consumers and other stakeholders, they are sensitive to the effects of business on brand value, revenues, and company valuation.Keywords: digital transformation, Sustainability, corporate sustainability, aligning

Journal of Optimization in Industrial Engineering, Volume:16 Issue: 34, Winter and Spring 2023, PP 119 -127With global warming and energy shortages, smart grids have become a significant issue in the power grid. Demand response is one of the basic factors of smart grids. To enhance the efficiency of demand response, an intelligent home appliance control system is essential, which prioritizes the start-up of electrical appliances according to the necessity of use and efficiency. To properly manage the demand response, utilities use different signals such as price. One of the pricing methods that can be considered is different pricing for electrical appliance clusters. In this article, appliances are clustered by the K-means and hierarchical clustering based on the characteristics of the appliances themselves, such as the appliances’ extent of consumption, the type of use of home appliances, how home appliances work, the ability to change the working conditions of home appliances, home appliances usage time, etc. It seems that the K-means clustering method outperforms the hierarchical method in this issue, due to its lower value of DB coefficient. In this method, home appliances were classified into three clusters. The silhouette coefficient was developed as a measure of the K-means clustering model performance, where the average silhouette coefficient of 0.6 indicates the satisfactory value of the model. Based on the results, it was found that the proposed clustering method can rationally classify different types of home appliances by selecting the appropriate characteristics since the appliances in a cluster are very similar to each other and can help users understand the operating conditions of the appliances.Keywords: Appliance, Demand Response, k-means clustering, Hierarchical Clustering

Economical, environmental, and social issues are significant challenges for industries and governments nowadays. The spare parts impose high inventory costs on the companies and require human resources, energy, and budget for the repair operations. These issues justify integrating repair, and inventory management decisions to reduce costs. Since the system is interacting with the environment, incorporating the sustainability dimensions with network design and planning decisions help managers to make more reliable decisions. We investigated the social and environmental dimensions to cover the sustainability dimensions of the spare part supply chain. These attributes contribute to industry-oriented properties in real-world problems. This paper investigates a multi-objective model to minimize costs while maximizing sustainability in a repairable spare part supply chain. Life cycle assessment (LCA) is utilized to assess social and environmental dimensions. Finally, the model is solved using NSGA-II with a priority-based encoding and decoding procedure. The findings shed light on contributing to formulating the spare part supply chain sustainability which integrates the network design and planning decisions resulting in more reliable outcomes.Keywords: Supply chain, spare part, Sustainability, NSGA-II, Inventory

This is due to the different aspects of the topic and the different results in various organizational contexts and time periods. Although marketing and business plans are similar, there are differences between their characteristics. The present study attempted to analyze the relationship between the alignment of marketing and business strategies with the organization’s financial performance in a five-year period from 2014 to 2018 in a group of companies registered in Tehran Stock Exchange.MethodologyThe configuration theory in strategic management was used to develop the conceptual model. The marketing strategy was divided into the configurations of aggressive, mass, minimizer, and value-related, and the business strategy was divided into the four configurations of prospector, low cost defenders, differentiated defenders, and analyzers. Research hypotheses involved the relationship between the combination of configurations and the organization’s financial performance. One of the well-known tools for identifying marketing strategy is the self-typing paragraph approach. The Miles framework was used to identify the business strategy. To measure the performance, a questionnaire was used with six factors including sales growth volume, market share status, net profit growth status per share, operating profit margin status, net profit margin, and P/E ratio. The list of the Iranian stock exchange companies was used to select the companies. These companies were filtered based on three conditions. The first condition was the existence of an independent marketing department in these companies, the second condition was the existence of a competitive or semi-competitive environment, and the third condition was the companies’ lack of a joint venture investor. Thus, 108 companies cooperated with the research. First, marketing and business strategies and organization’s financial performance were identified. Then, the companies were divided into two groups including aligned and non-aligned groups. After that, the mean test was used for the statistical comparison of the performance of the aligned and non-aligned states.Results and DiscussionAs the results revealed, the mean performance of the aligned states significantly differed from that of the non-aligned states. In the field of marketing strategy, the post hoc test showed that the mean performance of the aggressive strategy was higher than in other strategies. The value-related and mass strategies had a higher mean performance than the minimizer strategies but were not different from each other. In the field of business strategy, the prospector strategy and the differentiated defenders had higher mean performances than the low-cost defenders and analyzer. In general, the statistical results rejected the equality of mean performance in different combinations of business and marketing strategy.According to the research findings, four bodies were identified. The first body was the combination of the low-cost defenders with the minimizer strategy. In this body, the company's main focus was on maintaining the market share. These businesses reduce their risks by delaying the introduction of the product in the market until the product is established by others in the market. Adequate quality, low price and very wide distribution strategy are pursued by them. They generally focus on the product line and use the least amount of professional marketing staff. The second body was the combination of the differentiated defenders with the value-related strategy. In this body, the ratio of operating profit to sales was high. Also, the integrated chain of communication with customers was active, and the company used a relatively conservative and somewhat risky approach to activities. The company paid only some attention to market share and focused on maintaining the market. The company paid attention to capacity building, as compared to its competitors, and implemented the market-product strategy. The company considered its marketing strategy combination to be innovative, and high-quality products and the main value were in close relationship with the customer. They conducted mediocre marketing research and generally demanded a fair price. Their distribution strategy was somewhat selective, and they used moderate advertisement. In fact, the focus was on customer orientation, and there was a tendency for niches markets. The Third body was the combination of the analyzers with the mass marketing strategy. In this body, the ratio of the operating profit to sales was high. Also, an integrated chain of communication with customers and suppliers was active, and the company used a relatively conservative view. The company paid some attention to market share and focused on maintaining the market. There was a lot of focus on market-product strategy, but serious attention was also paid to cost reduction. The company was dominated by the engineering-oriented view. An extensive data analysis was performed every day for optimal decision making and long-term planning. These businesses generally produce high-quality products that follow market innovation and use very wide distribution channels. The fourth body was the combination of the prospectors with the aggressive strategy. In this body, the operating profit margin was taken into consideration, the integrated chain of communication with the customers and suppliers was active, and the company used a very risky view. The company paid serious attention to the market share. It was a leader in terms of innovation, diversity and capacity development, compared to its competitors, and fully implements the market-product strategy. The development of new markets was a priority and the company had an entrepreneurial outlook. These businesses usually produce innovative and high-quality products, and have a very close relationship with the customer and conduct a very extensive marketing research. This research is done to identify and encourage market segments where buyers tend to pay high prices. Buyers in these markets are selected with a selective distribution strategy and are contacted with through intense and focused advertising.ConclusionThese results indicate the proximity of marketing and business strategies and the direct effect of marketing strategy on the organization’s performance. The research contributes to managers’ knowledge of successful and high-performance alignments. Therefore, organizations can intensify marketing activities and reinforce their alignment skills.Keywords: Alignment, Business strategy, configuration theory, Marketing Strategy, Performance

صنعت نفت یکی از صنایع استراتژیک در کشورهای نفت خیز است، به همین علت تصمیم گیری درباره چگونگی بهره برداری حداکثر، با کم ترین هزینه همواره مورد علاقه سیاست گذاران در این زمینه بوده است. در سال های اخیر توجه به هوشمندسازی میادین نفتی به دلیل مزایای فراوان آن مورد توجه بسیاری از متخصصان این امر قرار گرفته است. با هوشمندسازی میادین نفتی و استفاده از سیستم های یکپارچه سازی عملیات تعداد حفاری ها و متعاقب آن هزینه حفاری کاهش یافته و از طرف دیگر با استفاده از تجهیزات هوشمند، تولید آب همراه نفت از میدان کاهش و کیفیت نفت تولیدی بهبود یافته و هزینه های تولید آب نیز کاهش می یاید. در این مقاله داده های میزان تولید و هزینه بهره برداری یک میدان نفتی در حالت مرسوم به حالت هوشمند تعمیم یافته و با استفاده از مدل سیستم دینامیک در نرم افزار ونسیم به بررسی عوامل موثر بر هوشمندی میدان نفتی و میزان کاهش تولید آب و هزینه حفاری میدان در حالت هوشمند پرداخته شد. از آن جا که کاهش تولید آب همراه نفت و حفاری بر هزینه تمام شده بهره برداری میدان تاثیر می گذارد، با کاهش کمبود تجهیزات و قدرت تامین کنندگان فعلی 143 هزار دلار در روز و با افزایش قیمت هر بشکه نفت 99 هزار دلار در روز صرفه جویی در هزینه ها می شود. از طرفی با کاهش قیمت هر بشکه نفت 86 هزار دلار در روز و با افزایش کمبود تجهیزات و قدرت تامین کنندگان فعلی 83 هزار دلار در روز افزایش هزینه ها رخ می دهد.کلید واژگان: هوشمندسازی, میدان نفتی هوشمند, سیستم دینامیک, تجهیزات هوشمند, حفاری, آب همراه نفتThe oil industry is one of the most significant strategic industries in countries with oil reserves. For this reason, politicians desire to know how to choose a condition with maximum exploitation but minimum cost. In recent years, most of the experts have been paying attention to intelligent oil fields owing to their advantages. Intelligent oil fields and operational integrated systems can reduce the number of drilling operations and as a result, lower the costs of drilling. On the other hand, intelligent equipment will decrease water production from the field, improve the quality of the produced oil, and reduce the costs of water production. This paper focuses on generalizing production data values and exploitation costs of the oil field, from the conventional field to an intelligent one. To this end, a model of the system dynamic was developed in VENSIM software to assess the effective factors on intelligent oil fields, the value of reducing water production, and lowering drilling cost in the intelligent state. Eventually, it was found out that the costs of drilling and water production are dependent on the price variation of each oil barrel, the percentage of the lack of equipment, and the power of current suppliers. The variation of each factor has a remarkable effect on the costs of drilling and water production with oil.Keywords: Intelligence, Intelligent oil field, Integrity, System dynamic, Intelligent Equipment

Energy is an important parameter in establishing various communications types in the sensor-based IoT. Sensors usually possess low-energy and non-rechargeable batteries since these sensors are often applied in places and applications that cannot be recharged. The most important objective of the present study is to minimize the energy consumption of sensors and increase the IoT network's lifetime by applying multi-objective optimization algorithms when selecting cluster heads and routing between cluster heads for transferring data to the base station. In the present article, after distributing the sensor nodes in the network, the type-2 fuzzy algorithm has been employed to select the cluster heads and also the genetic algorithm has been used to create a tree between the cluster heads and base station. After selecting the cluster heads, the normal nodes become cluster members and send their data to the cluster head. After collecting and aggregating the data by the cluster heads, the data is transferred to the base station from the path specified by the genetic algorithm. The proposed algorithm was implemented with MATLAB simulator and compared with LEACH, MB-CBCCP, and DCABGA protocols, the simulation results indicate the better performance of the proposed algorithm in different environments compared to the mentioned protocols. Due to the limited energy in the sensor-based IoT and the fact that they cannot be recharged in most applications, the use of multi-objective optimization algorithms in the design and implementation of routing and clustering algorithms has a significant impact on the increase in the lifetime of these networks.
