REVIEW EXISTING STRATEGIES IN CRISIS MANAGEMENT OF CONSTRUCTION PROJECTS FOR OPTIMUM USE OF CONSTRUCTION MACHINERIES (CASE STUDY LORESTAN PROVINCE, IRAN).

It is past more than forty years from entering heavy construction and mining machineries to cycle of activity and construction in Iran and always was given special attention to these machineries as a commodity asset in organizations. Output of machineries was depend on different factors such as type and building machinery, physical conditions, operators, complete management and coordination between all factors; whereas each machine during its life time is repaired partially or wholly and all its cost is depend on some factors such as delivery of machineries, work difficulty, number of hours of operation per year, annual useful life of machine, operator skill level of each machine, proper maintenance and timely repair it and market conditions of second hand machinery at time of sale, they are eventually placed in a position that machine owner should choose one of two options of scrape or rebuilt for costs optimal management. This study is descriptive and functionality which considered effective factors in machinery decision making to rebuild product and rate of success in each dimension's decision. In order to identifying and ranking factors, Delfi method and inferential statistical techniques for evaluation existence gap with optimal condition in each aspect were used and designed a questioner with 18 questions and 7 aspects and polled of expertise and finally means of reducing the gap was discussed.
