Given the existing economic situation, the role of management accounting in Iranian economic enterprises has been quite evident in the last two decades. Considering the economic crises, it is necessary to examine the indicators of adoption of management accounting innovations in times of economic crisis. Therefore, the present study aimed to identify the indicators of adoption of management accounting innovations in times of economic crisis and to present a model for its structural equations. The research was conducted in two parts: qualitative and quantitative. In the qualitative section, data analysis was performed by Delphi method and using interviews with 10 experts, including managers and deputies of the management accounting department of accepted companies and university professors. The analysis was conducted three parts: open coding, axial coding and selective coding and finally Delphi method. Based on the results obtained in the qualitative section, 103 sub-components and 6 main components were identified. The main components are: 1) economic crises; 2) economic indicators; 3) organizational culture; 4) information and communication technology; 5) Management indicators and 6) Crisis control indicators. In the quantitative section, using the indicators identified in the qualitative section, a questionnaire was designed and provided to a statistical sample including 180 people, managers and deputies of the management accounting department. Finally, the questionnaires were analyzed by PLS structural equation modelling. The results showed that economic indicators ,organizational culture, information and communication technology , and crisis control indicators as indicators of adoption of management accounting innovations in times of crisis.

Selecting suitable suppliers and assigning orders to them, is one of the most important strategic supply chain management activities. Therefore, first, in this research, a mathematical model for choosing the supplier in the supply chain in the framework of the operational research methods was proposed. Linear programming model with consideration of purchase costs and transportation costs with the meta-heuristic bee algorithm approach using MATLAB software was solved and analyzed. Therefore, the research method is applied in terms of purpose, and in terms of method is a descriptive mathematical type that was implemented in the form of a library and field studies. Information gathering tools, such as documentation tools, interviews with experts and production managers were used in relation to production. According to the nature of the research, which is modeling and solving by the algorithm, to determine the sample size were selected by cluster sampling method and random sampling method. Then to validate the mathematical model, lingo and Winqsb software was used, the solution obtained by both software, which is the optimal answer and optimal objective function, indicates the validity of the mathematical model.
