Nowadays, most of developed and developing countries, because of both limited resources and growing competitive markets, looking for to diagnose the causes of projects delay and are trying to develop solutions for decreasing amount of delay in next projects. In this paper initially notions related to delay, project risk management, Failure Mode Effects and Analysis (FMEA) method have been reviewed and also construction projects of Kurdistan state organization of schools renovation have been examined. Then a framework based on Fuzzy FMEA and AHP model have been proposed in order to recognize the most important risks and determining the amount of effects of these risks on main objective of projects (i.e. time, cost and quality) and estimating their occurrence probabilities. Meanwhile along with calculating importance coefficient of factors, some ideas to prevent or decrease consequences of these factors have been recommended

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
