Survival of production systems has become complicated with the emergence of new areas in business. In other words, changes in business environment, which are the results of changes in customers’ needs lead us to an uncertainty in making decisions; therefore there is a need to have a flexible supply chain to confront the changes. Agility is considered as a solution to enable mass construction associations to maintain in a competitive environment of housing industry in Iran. The aim of this study is to introduce a method to evaluate the agility of supply chain for mass construction associations. The proposed method of this paper designed questionnaires to evaluate the agility of supply chain based on identified criteria and indices. The questionnaires were filled by experts and scholars and then analyzed with SPSS software. Findings of this study show that the agility of the case study of this paper is ranked 2 out of 5 or 40%. According to the evaluations of agility, the highest score goes to financial and the lowest score belongs to information technology.

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.
