Logistics Planning and Its Role in Developing Construction Projects in Khartoum State

Review Article of American Journal of Transportation and Logistics Logistics Planning and Its Role in Developing Construction Projects in Khartoum State Omar Ismail Omar Mohammad, Ali Abdullah Alhakem Sudan University of Science and Technology, College of Business Studies, Khartoum, Sudan. There are lots of construction projects been implemented in Khartoum State in the last decades. And, in order to implement construction projects successfully, there should be a perfect flow of materials, services and information related to those projects. The provision of providing projects with those essential needs lies within the concept of the logistics management; so, there will be a critical need for developing perfect planning for logistics services. The provision of supplying construction requirements should be conducted and handled in best manner with all the related aspects including quality, safety, time and cost to the proper execution of the construction projects. Many projects are failed and terminated because problems of the flow of logistics services. Those problems are occurred as result of many factors, but bad planning of logistics services is the one of the most important factors. Thus, in order to implement construction projects, there is a great need for the logistics supply service. Because, without delivering construction inputs in the required manner to the location of project, the project shall never be executed. And, in order to provide the project with the needed inputs in the best way and at a required time, there must be an effective planning for the logistics services of projects; in details, there must be a greater concern with the processes of purchasing, transporting and storing, handling as well as flow of information of all materials that used in the execution of projects. The study finds out that applying project management as well as perfect planning of logistics services play vital roles ...

Build-Operate-Transfer Model and Its Role in Developing Railways Transport Section in Sudan

Review Article of American Journal of Transportation and Logistics Build-Operate-Transfer Model and Its Role in Developing Railways Transport Section in Sudan Omar Ismail Omar Mohammad Sudan University of Science and Technology. This paper focuses on a solution to the finance restrictions that obstacle the development of railways section in Sudan. Sudan is a big country with an area estimated at more than 1,800,000 km2. It owns variety of natural and other resources. The transportation system in Sudan specially railways suffers a lot of restrictions that affect its contribution to the national economy. Sudan railways is one of the longest railways in Africa with about 5,000 km. Railways were the earliest mechanical means of transport to be introduced in Sudan. The construction of the first railway line started in the last decade of the Nineteen century. Railways have been playing a significant role in transportation for long time. However, railways in Sudan lack passengers’ trains recently. Moreover, the capacity of freight trains is enough to meet just 10% of needed capacity. Also, most of the rails are very old and exceeded their expire date; and as the result a lot of derailments had been occurred. Also, most of the rail on the western lines are not suited to all of the diesels. Moreover, most sleepers are creosoted wood which differ from that used in the neighboring countries that use steel or concrete. And to overcome all these issues, there is a huge need of finance. However, lacking of finance is one of the main restrictions that face the development of railways section in Sudan. And, in spite of that, the Build Operate-Transport (BOT) approach could be the best option to deal with the current situation that faces railways section in Sudan. Build-Operate-Transport Approach (BOT) is a well-known method of initiating, financing ...

Determining the Best Plan for Malls Parking Lot Based on Fuzzy Analytic Hierarchy Process Model

Research Article of American Journal of Transportation and Logistics Determining the Best Plan for Malls Parking Lot Based on Fuzzy Analytic Hierarchy Process Model Yixin Deng1*, Yulin Chen2 1College of International Communications, China Three Gorges University, Yichang, 443002, China. 2College of Science, China Three Gorges University, Yichang, 443002, China. With the rapid development of social economy, the number of family cars has entered a period of rapid growth and the consequent urban parking problem has become increasingly prominent, gradually becoming one of the problems facing cities in China. The regional planning of parking spaces can expand the number of parking spaces within a unit area. Therefore, considering safety, convenience, efficiency and other factors, how to maximize the number of parking spaces is the key to solve the parking problem. Based on the triangle division of Abdelfattah model and the analysis of PSU planning theory, the planning of mall parking lot is more realistic. This kind of planning maximizes the number of parking spaces on the basis of greatly increasing the flexibility of vehicle entry and exit, which is more conducive to our life. Keywords: Parking lot; Fuzzy analytic hierarchy process (AHP); Nonlinear programming; Abdelfattah model ...

Livestock Exports Growth in Sudan and Effect of Transport Section

Review Article of American Journal of Transportation and Logistics Livestock Exports Growth in Sudan and Effect of Transport Section Omar Ismail Omar Mohammad Sudan University of Science and Technology, College of Business Studies This paper presents guidelines to the needs and restrictions that affect the growth of Sudanese livestock exports resulting from the weakness of transportation section. Sudan has a huge livestock population. The livestock has a great contribution in the local economy. The production of livestock in Sudan is increasing effectively in the recent decades. Also, the contribution of livestock to exports has witnessed a gradual growing in the past few decades. The weakness of road and transport infrastructure, however, is affecting the growing of livestock export in Sudan. The livestock production is concentrated in rural areas that far away from the main roads and unconnected to them by paved roads. The road quality, in Sudan, is very poor. The infrastructure does not cover most Sudanese geographical area especially agricultural and livestock areas. Also, the cost of transportation is very high in comparison with international cost. Moreover, road maintenance is very weak and not cover all roads networks. And, there is a lack of finance for new road projects. This study finds out that the roads’ situation in Sudan is not helping the current growing progress of livestock exports and seriously declines that growing.
