Agricultural mechanization plays a crucial role in driving agricultural development and is considered one of the most capital-intensive inputs in the agricultural sector. Effective supply chain management is a crucial necessity for improving the quality of agricultural machinery and reducing operational expenses in agricultural mechanization. This is imperative for the advancement of agricultural mechanization. The present research aims to identify the primary structures of the supply chain for rice agricultural machinery in the provinces of Gilan and Mazandaran in Iran. The study also examined the important functional aspects of the chain members, including manufacturers, importers, retailers, and farmers who serve as the ultimate consumers of the chain's products. Furthermore, the research delved into the processes that govern the supply chain.

Measuring supply chain performance involves utilizing the Supply Chain Operations Reference model (SCOR) with five distinct dimensions: cost (12 questions), responsiveness (22 questions), flexibility (16 questions), assets (13 questions), and reliability (30 questions). The study data were analyzed using SPSS software. Additionally, latent variables were generated at each level of the hierarchy by using the variables from the aforementioned model. The normality of the variables was assessed using the Kolmogorov-Smirnov test. The evaluation of normal variables was conducted through a one-sample t-test, while abnormal variables were evaluated with a one-sample Wilcoxon test. Furthermore, descriptive analysis of the expectations and constraints of manufacturers and importers regarding rice machines was carried out.

The Wilcoxon test results indicate the impact of commitment, cost management, and communication on the average test value. The variables of normal distribution such as human resource management, quality management, strategic organization, flexibility, responsiveness, performance, and reliability in stores, exhibit significant deviation from the mean value. The majority of store managers and agricultural rice machinery dealers lack formal education in the field of agricultural machinery. Including individuals with educational backgrounds in agricultural machinery at various stages of the supply chain will likely improve the dissemination of information throughout the chain. Employing dependable techniques for transmitting accurate information regarding consumers' quality requirements can assist suppliers in manufacturing or importing superior-quality machinery. This approach not only minimizes uncertainty in the supply chain and streamlines inventory management but also reduces the lead time for meeting consumer demands.

The continuous demand for rice agricultural machinery in Iran has resulted in the bullwhip effect phenomenon being perceived as a less significant challenge in the supply chain. Currently, local manufacturing enterprises have relatively limited knowledge regarding the market and technical needs of rice farmers compared to their foreign counterparts. It is advisable for manufacturing companies to broaden their comprehension of consumer behavior and needs by diversifying their market evaluation techniques.

In this study, the supply chain performance of rice farm machinery at retail level in Guilan and Mazandaran provinces was evaluated using SCOR model. Rice machine dealers were evaluated  in five sections using 93 items. Based on the results of single sample T-test, the variables of efficiency, coordination and integration were significantly higher than the mean value. The clustering process of sales agents was based on the average items. Clustering results showed that the performance of sales representatives two main levels: desirable and undesirable. In order to improve the supply chain management situation, the performance of nearly half of the stores should be corrected. In this study DEA was proposed as a method for evaluating the efficiency of the SCOR model, which is one of the innovations of this research. The results of the DEA confirmed the cluster analysis results and the efficiency of about half of the units was calculated equal to one. Based on the results of the study, in order to improve the performance of rice agricultural machinery stores, it’s better to focus on measures that improve quality of service delivery and increase customer reliability.

The aim of supply chain is to reduce cost and increase service level. Distribution has an important role in supply chain management. Combine owners cooperative has an important role in reducing wastages before harvest due to delay. Agriculture products are sensitive to an environment that is changing constantly, since, needs for appropriate reactions of cooperatives has doubled. Requirement for respond effectively to these changes is to achieve agility. In this research agility criteria identified from previous studies. A Questionnaire was prepared and completed in order to identify the most important measures for agility of cooperative distribution chain. The important agility criteria were identified and were rated by using SAW method which after calculating A*, three parameters including sensitive and responsive to the market and customers, speed of work and introduction of a new product with value of 0.08620 were concern primarily and correct planning, reduce costs, and consolidate tasks and process, using IT, customer satisfaction, flexibility, quality of services and the development of staff skills values are 0.082328, 0.077243, 0.074230, 0.073355, 0.071509, 0.069464, 0.065749 and 0.063601 respectively and were in second place to ninth.
