Ambidexterity is a company's capability to manage operations and strategy simultaneously and effectively, facilitating innovation and adaptation to market changes. Companies must be able to maintain operational efficiency and stability while also innovating and adapting to market dynamics. Ambidexterity enables companies to manage operations and strategy effectively and efficiently while at the same time, facilitating innovation and adaptation to market changes. This leads to an increase in company performance, such as increased revenue, increased market, and increased operating efficiency. It is also necessary that there are several mediating variables, such as effective supply chain collaboration, supply chain management, and innovation capability, which influence the relationship between supply chain ambidexterity and firm performance. This study aims to determine the extent to which ambidexterity can influence supply chain performance and how the role of lean and agile supply chains mediates the relationship between these variables. The research method used in this study is a quantitative approach. The number of samples analyzed in this study was 225. The results of the study concluded that ambidexterity helps companies to overcome pressure to optimize short- and long-term performance, maintain agility and flexibility in adapting to changes in the business environment. Studies on ambidexterity and supply chain performance have shown that ambidexterity can help directly optimize supply chain performance but can also amplify the positive impact of practices such as lean supply chain and agile supply chain. The implications obtained from the findings are that companies are expected to improve operational efficiency and effectiveness and have the ability to adapt to environmental changes and market demands.

Unexpected occurrence like natural calamity, abruptly change in customer demands, upgradation of technologies, necessity of compatible suppliers etc. is the most challenging issues even for efficient global supply chain management. Therefore, modeling of responsive supply chain is an emerging technology for sustaining any firm/industry in future competitive environment. In this paper, an attempt has been made to not only analyze the performance of efficient supply chain management but also how to improve the performance of existing supply chain with the objective of developing a modeling of responsive supply chain management. The complexity of the model is also highlighted with the help of numerical example. This paper also explores the possibility to mathematical modeling of the responsive supply chain which will be an emerging topic for researchers and practitioners. The modeling of responsive supply chain can be employed as a competitive strategy for e-commerce, green supply chain, and compatible supplier selection problem. The another salient feature of this paper is that a distinct comparative literature review of the lean, agile, efficient, and responsive supply chain management has been presented.

Impotent planning system in house providing process is the result of inadequate housing management system in theoretical, empirical, and operational fields. In addition, Mass Construction industry in Iran confronts with other problems such as instability in raw material prices, unsteadiness in production and investment laws and regulations, frailty of transportation infrastructure, international sanctions and etc. Furthermore, customers’ needs, lower costs, and greater customizations lead mass producing to search for new solutions and novel producing system. Agility is offered as a strategy to enable Mass Construction associations to be maintained in the competition of constantly changing market in Iran. In such a market, previous approaches lose their capabilities in supply chain. Thus to achieve agility by Mass Construction association is the chief aim of this study. This study is descriptive-analytic and can be identified as developmental –functional considering its target. After surveying previous research literature and using experts’ opinions, we investigated final agile sub criteria of supply chain and then we used interpretive- structural modeling approach to determine the relation among sub criteria and to offer an agile supply chain model. Surveying research literature and experts’ opinions lead us to identify 8 criteria (society, government, financial, information technology, market, partnership, quality and technology) and also 22 sub criteria for supply chain’s agility. Then the results were analyzed through interpretive-structural approach and relation of criteria and sub criteria and their consequence were achieved. These relations showed that government and infrastructure investment, culture, regulations and responses to social and environmental issues are the basis of agility in mass housing productions’ supply chain. This model helps supply chain managers to have strategic planning to enhance agility in supply chain and find effective sub criteria and criteria to invest on.

Agile supply chain plays an important role on having efficient production planning. There are different factors affecting the efficiency of a supply chain and the attempt of this paper is to find the most important elements in agile supply chain. The proposed model of this paper gathers decision makers & apos; opinions and based on DEMATEL technique determines the most important items. The preliminary results of this survey indicate that we could divide the factors into four groups and two elements including automation and utilization of technical tools of relations and information play the most important roles among other factors.

Today automotive companies must pioneer in strategies such as the agile supply chain for competition and various demands of customers. Considering the importance of agile in choosing a supplier at the supply chain, this study tries to identify and evaluate agile activities in SAPCO Company suppliers. Then, using principal component analysis of factor analysis, a number of related activities are divided into smaller groups called factor. The results are used by SAPCO to determine agile patterns in selecting a supplier with emphasis on similarities and differences and create agile portfolio. The study can help SAPCO identify criteria and making decision in the field of agile at suppliers.
