Analysis and evaluation of agricultural systems use these criteria: energy, economic, agronomy, environmental conservation and time. Because of time importance indicator for reducing timeliness cost, project scheduling techniques are used. Graphical Evaluation and Review Technique (GERT) is widely used as a tool for managing projects. In this research GERT Networks were used and operations scheduling of sugarcane production (land preparation, planting and preserve operations) in Khuzestan province of Iran as a case study was analysed, by using WinQsb software. Critical activities, events and path were determined. The earliest project completion time is 214.03 days. The results show a high potential for operations scheduling of sugarcane production.

Third, ranking the influential sub crisis factors from the all sub factor list and provide a single list without considering the initial list crisis through WASPAS model. Finally, The result of the crisis effects rating, seen that the most crisis effects rating in the Khuzestan construction industry is the economic crisis, followed by the market and real estate, and then insurance, maintenance, after that respectively, logistics, and materials crises. Identify the crisis is the main part of crisis management; the obtained results help construction crisis managers and all stakeholders to achieve sustainable development in construction projects. Identifying and prioritizing construction-specific crises allow sustainable crisis managers to concentrate to be successful projects.
