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.

Unified Modeling Language (UML) has been recognized as one of the most popular techniques to describe static and dynamic aspects of software systems. One of the primary issues in designing software packages is the existence of uncertainty associated with such models. Fuzzy-UML to describe software architecture has both static and dynamic perspective, simultaneously. The evaluation of software architecture design phase initiates always help us find some additional requirements, which helps reduce cost of design. In this paper, we use a fuzzy data model to describe the static aspects of software architecture and the fuzzy sequence diagram to illustrate the dynamic aspects of software architecture. We also transform these diagrams into Petri Nets and evaluate reliability of the architecture. The web-based hotel reservation system for further explanation has been studied.
