من المعروف أن نشاطي الشراء والتخزين ركنان اساسيان من اركان عمليات المؤسسات التجارية أو الصناعية أو الخدمية، وذلك نظراً لضخامة المواد المطلوبة في صناعة وتجارة اليوم. لذا أصبح من الضروري الاهتمام الكافي بهذان النشاطان، ولهذا السبب كانت فكرة هذه الدراسة. في هذه البحث تم تغطية الإطار النظري بمواضيع تشمل إدارة المشتريات وإدارة المخازن، يلي ذلك الإطار التطبيقي المتمثل في الدراسة الميدانية بجمع المعلومات من ثلاث مؤسسات ليبية كبيرة متنوعة المجالات، كعينة على المؤسسات الليبية، وهذه المؤسسات هي الشركة العامة للكهرباء، وشركة مليته للنفط والغاز، والشركة العامة للنقل البحري. كذلك تم إجراء دراسة إستبيانية بتوزيع استبيان لإدارة المشتريات وآخر لإدارة المخازن على عينة عشوائية لكل من هذه المؤسسات. ومن خلال النتائج المتحصل عليها من هذه الدراسة (البحث)، توصلت الباحثة لعدة استنتاجات عن اداء ادارتي المشتريات والمخازن في المؤسسات الليبية، ومن هذه الاستنتاجات انبثقت مجموعة من التوصيات التي تعتقد بان إتباعها قد يساهم في انجاح اداء ادارتي المشتريات والمخازن، وبالتالي انجاح ادارة حركة المواد في المؤسسات الليبية. ومن خلال هذه الدراسة، تم التوصل الى تصميم نموذج قدمته كمقترح لإدارتي المشتريات والمخازن، والتي تشمل طريقة الشراء والتخزين والفحص والصرف، وتم كذلك اقتراح نموذج لهيكل تنظيمي يتبع الاسلوب العلمي المطور لإدارتي المشتريات والمخازن.وترى الباحثة في هذا المقترح، ضرورة جمع إدارة المشتريات وإدارة المخازن في إدارة واحدة، يرأسها مدير واحد يتبع مدير الشؤون التجارية والمالية، يطلق عليها إدارة المواد. وينتج من دمج المشتريات والمخازن، ومراقبة المخزون في إدارة واحدة، مجموعة من المزايا غير متواجدة في النماذج الموجودة في المؤسسات الليبية تحت الدراسة. ونتيجة لان نشاطي الشراء والتخزين يعتبران نشاطان خدميان مهما اختلف تخصص المؤسسة التابعان لها، سواء كانت هذه المؤسسة إنتاجية صناعية أو تجارية أو خدمية، فان هذا المقترح من الممكن استخدامه في مختلف المؤسسات الليبية.وباعتقاد الباحثة بان هذا المقترح المقدم سيساعد في مراقبة حركة المواد، لأنه يربط المخازن بالمشتريات في مستنديه واحدة، ومن خلاله لا يتم الشراء إلا بعد التأكد من عدم وجود المواد بالمخازن، وبالتالي يمنع تكدس المواد وازدواجية الطلبيات. ايضا فإن هذا المقترح يجعل عملية الدفع مؤجلة حتى وصول المواد للمخازن وفحصها فنياً، وعند التأكد من سلامتها ومطابقتها للمواصفات، عندها فقط يتم الدفع وهذا يمنع تكدس المواد الغير مطابقة للمواصفات في المخازن ويحد من خسائر الشركة. Abstract It is well known that the purchase and storage activities are considered to be the fundamental pillars of the business, commercial, industrial or service operations, due to the magnitude of the required materials in the manufacture and trade of the day. So it became necessary to give adequate attention to these activities, and that’s why the researcher had thought of the idea of this research.In this research, the theoretical framework covering topics include procurement (purchasing) management and warehouse (inventory and storage) management; followed by a practical framework of the field study to collect information from the work of three large Libyan institutions in a variety of fields, namely, the General Electric Company, Mellitah Oil and Gas Company, and the General Company for Maritime Transport, as a sample of the Libyan institutions. Also, the study includes the distribution of questionnaires to procurement management and warehouses management on a random sample of each of these institutions.Through the obtained results from this study (research), the researcher reached several conclusions about the performance of the management of procurement and warehouses in the Libyan institutions and these conclusions emerged a set of recommendations. It is believed that if these recommendations were followed, then they may contribute to the success of the performance of the management of procurement and warehouses, and consequently to the success of the management of movement of materials in the Libyan institutions.An important model design presented as a proposal for the management of procurement and warehouses has been reached, which include a method for purchases, storages, inspection, and payment. Also an organization structure model was proposed that follows the advanced scientific method to manage the procurement and warehouse. Since the purchases and the warehouses are considered two service activities; then no matter what type of activity the institution is following; whether it is an industrial productivity, commercial or service, this proposal could be implemented in various Libyan institutions.The researcher beliefs that this proposed model will help in monitoring the movement of materials, it connects warehouses with purchases in just one documentary, and through it, purchase is only allowed after making sure that there are no materials in the warehouses, and thus prevents the accumulation of materials and duplication orders. Also, this proposal makes payment deferred until the arrival of materials to warehouses and technically inspected; when you confirm the safety and compliance with the specifications, only then the payment is made, and this prevents the accumulation of non-matching material to the specifications in the warehouses and reduces the company's losses.

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)

Boot contracting and its useability scope in implementing construction projects in LibyaThe development of construction projects is considered among the most important indicators of development and progress of society. Numerous project areas that have witnessed development in Libya in recent decades, including construction and building, whether infrastructure projects, productivity or investment projects. As the engineering projects department is one of the most important elements of the success of the project, and is therefore important to develop contractual aspects associated with the urban development stages in the country. Despite, the role posed by construction projects in our country, but they face through their various stages of implementation to a number of problems that may not be addressed in regulations and legislations currently in force, and this call to think of changes or additions to these systems, such as the proposal of new contractual patterns that contribute to the implementation of these projects in the best possible way. Therefore, this research aims to propose concession contracts, which are a range of patterns differ in application depending on the type of project contracted, and these contracts share the notion that they are projects owned but public authorities and funded from outside the general budget, the type of contract selected is the BOOT (Build, Operate, Own & Transfer) contract to be the topic of this study. The stage approached by Libya of the large urban development through the implementation of large construction projects requires the preparation of budgets and human resources, equipment, materials and machinery, and the question before us is whether the implementation requirements available to the general implementation bodies; that includes budgets or human work staffs of engineers, supervisors and workers and suppliers, as well as operators and administrative officials allows for the implementation of these projects? The importance of this research lies in the opening of a broad area both to domestic and foreign investments, and give the opportunity for the private sector to participate in the anticipated urban boom in the use of concession contracts (BOOT (Build, Operate, Own, Transfer)), and these promote the public owner of the project to grant the concession right to a private entity to implement the project and this entity is known as the concession authority, it implements the project and has temporarily ownership of it and operate it for a period of time known as concession period, and that is determined in the contract and at the end of the period the whole facility is delivered fully operational and without any expenses to the public authority the original owner of the project, and the financier could recover the costs of the implemented project through its operation and granting the good investment returns. This research adopts the methodology of the analysis of a sample of administrative contracts to identify the problems encountered in construction projects, causes and classification, and the study has been supported by information compiled by distributing a questionnaire in addition to interviews with the elements of the study sample that was represented in a group of engineers and experts who have been carefully selected to represent most of the public authorities the owners of the projects as well as advisory bodies, after the data collection through methods mentioned above, which is the practical side of the study, information was also obtained through the search in scientific reference sources concerning concession contracts, definition, use and features, etc. this is the theoretical side. It has been analyzed by statistical analysis methods and reach recommendations and proposals to help use concession contracts as a solution to some of the problems facing construction projects in Libya, also reach the preparation of a proposal for a principle concession contract model that can be used by stakeholders in their contracts, with the recommendation to keep research in this field to overcome some difficulties that might result from using this type of contract.
