The supply chain of the food industry is very important for countries. In recent years, occurrences such as floods, frost, heatstroke, shutdown of some layers of the supply chain, cause a ripple effect in the supply chain of food products. The occurrence of disturbances and specifically the ripple effect can make the country face many challenges, therefore it is necessary to identify and analyze the strategies to deal with the ripple effect. This research has been done in two stages: qualitative (with the aim of identifying coping strategies) and quantitative (with the aim of scenario modeling and analysis). The method of analysis is thematic analysis in the first stage and fuzzy cognitive map in the second stage. The findings show 84 primary codes that were grouped into 21 sub-categories and 4 main categories of "Strategic Management", "Operations Management", "Compilation and Correct Implementation of Laws" and "Supply Chain Management". The analysis of backward scenarios shows the importance of "supplier relationship management", "cooperation and coordination in the supply chain" and "contingency plans", and the analysis of forward scenarios shows the importance of "monitoring environmental changes" and "strategic plan”. Focusing on short-term plans, improving the capabilities of managers in the field of decision-making and problem-solving skills, adjusting supplier selection criteria, improving the design of the supply network based on backup locations, and the existence of safety stock for strategic goods should be the attention of industrialists.

In today's competitive and global economy, the life and activity of the organization is determined by the ability to compete and adopt the most appropriate policy against environmental changes. In this regard, the knowledge about the performance of all aspects of the organization is vital for management decisions. Although extensive studies has been carried out in evaluating the performance of organizations through the balanced scorecard (BSC), but there are defects such as focusing on a one-way causality, ignoring the replacement between indexes and between the four-way, and equality between weighted value of indexes. In the present study, focusing on the casual relationships between factors and also between the direction and strength of these relationships, we tried to improve the balanced scorecard method. To do this, first all the relationships between the four dimensions of BSC were determined using fuzzy cognitive map, and it was then used to obtain a network structure, which was used later to create a network data envelopment analysis (NDEA) model. Finally, this model was used to evaluate the performance in Maskan Bank of Fars province. The results show that between 82 branches investigated, 15 branches were efficient and the others inefficient.

Delay is a common occurrence in the country's construction projects. Identifying delay factors in these projects and determining the influence of these factors is necessary to achieve the objectives of management. In this study, the effective delay factors on construction projects are identified by using previous studies, project documents and experts opinions. Since these factors affect on each other, the fuzzy cognitive map has drawn for effective factors and assessment factors or management objectives. Then, the effect of each factor on the assessment factors are evaluated by using hybrid learning algorithm and prioritization factors are done by using fuzzy data envelopment analysis. The results of the survey in West Azerbaijan province show that “supervision technical weaknesses for overcoming technical and executive workshop problems”, “inaccurate estimate of workload, required equipments and project time” and “the multiplicity of decision centers on the doing of projects” are the most important delay factors in construction projects
