Abstract History of project management return to ancient times since the construction of the great projects that immortalized in history like pyramids, Wall of China, the Gardens of Babylon And many more projects that still witness to the civilizations until today. And for certainly, that difficult and complex project needed many equipment, materials, and human resources... And there is no doubt, that it had been using an administrative system in these projects, but so far, no historian has found any documented information about how they did it! Our present time of competition and development in all fields, specially industry, which it’s measurement is the most important criteria for measuring the development of any community, and there is many types of industries, including the construction industry, which has grown clearly on all parts of Libya, whether in infrastructure projects or investment projects. Despite the important role of construction projects in Libya, but it is suffering through it’s life cycle to a many of problems, leading to delay the completion of these projects. And in this thesis a study applied on construction projects to obtain depending on the questionnaire prepared in advance in compliance with elements of the academic view, and then doing the necessary statistical and computer-aided analysis and the use of modern software then discuss the results in details. Thesis includes the explanation and the analysis of findings that has been done for the problems and determines the impact of these problems on construction projects on (duration, cost and quality)

This paper identifies the most affecting factors that enhance the quality of the decision making process within some Libyan oil and gas companies. Based on the developed questionnaire along with the literature review, the analysis showed that it is a challenge to processing the proper procedure for making decisions. However, most decision makers are found to be focusing on using simple tools for making their decisions, whereas, lacking of an effective communication network during making decisions are considered with a negative impact on making the proper decisions within most surveyed companies. Furthermore, it was found that, the procedures for making decisions within most surveyed companies could be considered as the most crucial for improving the quality of the decision making processes, followed by the used tools and techniques, whereas, communications as a factor influencing the processes of making decisions is found to be at the lowest level throughout the entire decision making processes. arabic 15 English 98

Abstract Been implemented breakwater's main port of Tripoli Maritime as it now stands during the seventies, and once it had completed was the barrier to damage, due to the storms that swept the region during the early eighties, which led to the collapse of some of its parts in full, as a result of inadequate design, of miscalculation wave design, and change position of the barrier from the previous track, behind the rocky outcrops, to the edge of the reef. In 1982 was the redesign of the barrier, according to a re-evaluation of the climatic conditions of the region, but the rehabilitation work on the barrier does not run out for a period in excess of 17 years, leading to increase the size of the damage, to the extent that I consider him that the design of 1982 is no longer appropriate for the development of barrier timely, therefore, been re-design in 1999, but that the work of re-construction, and implement the necessary reforms, delayed again to the beginning of the year 2010, ie about 11 years old again, and therefore this study was to assess the adequacy of project designs for the case of art based upon the barrier currently, both in terms of different design parameters or the degree of deterioration of the concrete elements of the barrier, has been done by comparing the data collected and the final design of the project in 1999, what has been compiled from the current dat The study concluded, that the data upon which the determinants of basic design, especially the wave design should be reviewed through the availability of a new climate data, and methods and the amount of proposed reforms of the concrete elements are no longer sufficient for the language of these elements of damage
