    JEL Classification System: L920; R420The purpose of this study is to understand which factors impact more in the transshipment container port selection process in Gibraltar range. Analytical Hierarchy Process is applied through a survey. A random sample of 27 respondents ranked criteria based on pairwise comparisons and evaluated transshipment container ports through a 5-point Likert scale. The results suggest that vessel turn-around time, the proximity to the main navigation routes and the handling and storage cost of containers are the criteria that most impact in the transshipment port selection process. Further analysis could also extend to the switching costs in the transshipment business through previous cases, framing a cost-benefit analysis. Another future direction for research is a study in transshipment port selection with a higher number of respondents, comparing different perspectives, from maritime carriers to terminal managers, amongst others stakeholders. The results suggest that Port of Algeciras is the one that most fulfills productive criteria; Port of Tanger is the most competitive regarding costs; Port of Valencia has been able to balance transshipment and gateway services. This study is one of the first attempts to demonstrate the theoretical concepts of transshipment in one of the busiest bottleneck areas. The value of this study relies that academics and professionals may have supporting evidence that costs and productivity are the most valuable transshipment port criteria. The current situation in the transshipment in Gibraltar range could also be valued by port managers to define and prioritize new investments.O objetivo deste estudo é perceber quais os fatores mais relevantes na tomada de decisão de um porto de contentores de transshipment na zona do Estreito de Gibraltar. O método Analytical Hierarchy Process é utilizado através da construção de um questionário. Os 27 inquiridos hierarquizaram um conjunto de critérios através de comparações aos pares e avaliaram os portos através de uma escala de Likert de 5 níveis. Os resultados obtidos sugerem que o tempo de transbordo, a proximidade com as principais rotas marítimas e o custo de transbordo e armazenagem de contentores são os critérios mais relevantes aquando a tomada de decisão. É recomendada uma maior investigação, abrangendo os custos de troca de um porto transshipment, através do estudo de casos anteriores, construindo uma análise custo-benefício. Outra possibilidade passa pelo estudo do processo de seleção de um porto transshipment com um maior número de inquiridos, comparando perspetivas de diferentes intervenientes. Os resultados sugerem que o porto de Algeciras é o que melhor preenche os critérios de produtividade; o porto de Tanger é o mais competitivo em termos de custos; o porto de Valência tem sido capaz de apresentar um equilíbrio como porto de transshipment e como porto gateway. Este estudo é um dos primeiros a aplicar os conceitos teóricos associados ao transshipment a uma das áreas geográficas mais relevantes para o negócio. Académicos e profissionais dispõem assim de evidência prática de que os custos e a produtividade são dos critérios mais relevantes no processo de decisão, ajudando-os a definir e priorizar novos investimentos

    Merged with duplicate record 10026.1/2833 on 10.04.2017 by CS (TIS)Inland container transport has intensified over the past thirty years in Taiwan. It is closely related to inter-port competition and port selection by container carriers. In the 1980's, large containerships only berthed at Kaohsiung port due to the limit of container terminal operation capacities of Keelung port and the carrier's regional hub port decision in the country region. The container traffic of the south-north motorways made them more crowded and increased road maintenance expenses. The purpose of this research is to study inter-port competition and inland container transport flows in Taiwan. Although Taiwan is an island, the freight transport policy has been focused on rail and motorway rather than sea transportation. Therefore, it is intended to study the contexts of inland container traffic flows and the inter-port competition model. Following from this, the main objectives are to understand the details of container ports in order to identify the major criteria and variables related to the development of the intermodal freight transport system and then to create an integrated decisionmaking process model as a framework to help the public sector make quality decisions. We designed, tested and evaluated a public involvement process that identified public values for use in the development of an intermodal transport system for the container port. The methodology of this research includes the development of a Multiple Criteria Decision-Making (MCDM) model based on the Analytic Hierarchy Process (AHP) and validated by the use of priority setting for the intermodal transport system at Kaohsiung port as a case study. The main idea behind mathematical programming is the optimal selection of a set of research activities given limited resource availability, decision constraints and the pursuit of multiple objectives. A final model addresses the simultaneous analysis of the selection process clearly able to be traced back by all parties. This research developed a framework that will enable the public sector to make better decisions when selecting intermodal transport system proposals and also save decision-makers time and effort

    Abandoned housing projects is a relentless global issue which carries no positive value to involving stakeholders, economy, and sustainable aspects as well. Abandoned housing projects in Malaysia had prevailed since 1970 and the numbers are heavily escalating regardless of the Malaysian government’s efforts to curb the issue through promulgation of numerous incentives, policies, and laws. The incompletion of housing project could detriment the surrounding environment and social aspect as well as negatively impact the economy at a national scale. Nonetheless, homebuyers are the direct victim of this matter following the un-fulfillment of their intention to own a property in addition to extension of commitment for rental arrangement. To certain extent, unfortunate homebuyers would become ineligible for international travel and loan application from financial institutions ensuing failed housing loan payment. Therefore, the aim of the study is to analyze the factors that contribute to the abandonment of housing projects and its impact towards the nation, environment, and society. Through semi-structured interview session with 10 expert panels with the information generate from extensive literature review from previous study, several factors and impacts had been listed. A quantitative research methodology was conducted for data collection through a well-designed questionnaire which was developed based on the extensive literature review, semi-structured interviews, and discussions with expert panels. The 100 respondents in this study incorporated population of housing development stakeholders such as developers, contractors, consultants, and local authorities. Data collected was analyzed using the descriptive statistics of Ordinal Logistic Regression (OLR) method to satisfy second objective of the study whereby the relationship between each factors that contributes to the abandoned housing project and the project status was obtained. Subsequently, the probability for 3 category of project status was also developed to illustrate the probability of project status. The third objective of this study determines the solution priorities to mitigate the abandoned housing project through a pair wise questionnaire survey. This study utilizes Analytical Hierarchy Process (AHP) to derive the weighted value for each criterion by comparing the criteria with several alternatives to which the highest value would indicates the best solution to mitigate the abandoned housing project. The last objective is developing the prediction model to mitigating the abandoned housing project by combining the result gathered from objective two and objective three. Finally, by combining the finding from objective 2 and 3 the prediction model to mitigate the abandoned housing project developed. The findings conclude that the main factors of abandoned housing project are financial factors, followed by project participant factors, project management factors, market signal, procurement factors, and lastly, external factors. During the project monitoring process, the AHPM can displayed capability in predicting project status with regards to the issues (factors of abandoned housing project) faced in each project. In addition, most of the respondents stressed that developers facing financial difficulties should prepare alternative fund in order to settle their financial problems, such as by utilizing the developer community cooperation fund. The respondents agreed that the issue could be rectified through proper planning during preliminary study, proper scheduling during the construction phase, incorporating public private partnership (PPP), joint venture, and adequate study on the market signal. These findings could assist the stakeholders involved in mitigating the problems of abandoned housing projects in Malaysia

    Container terminal capacity is a crucial issue for port and terminal operators nowadays as it is one of the key points for their success and increasing their competitive market position in the maritime industry. Therefore, researchers have tried to find solutions for the over capacity problem that faces many terminal operators. This research suggests dry ports as one of the most suitable solution for this problem through proposing a structured framework to adopt the right policy decisions for Dry Port location and capacity. To achieve the presented framework some areas were addressed in detail to have the full picture clear. The current status of the global container sector was assessed, also, the main capacity problems of container terminals with a view to reviewing the suggested solutions was investigated, hence the need for dry ports. In addition, policies for providing optimal location and capacity decisions for container terminals were identified. A technique that supports assessing container terminal location and capacity policy decisions with particular reference to dry ports were developed. Moreover, a case study on Alexandria International Container Terminal for validating the results was conducted. The current research was facilitated by experts from the maritime transport industry, through the application of the Delphi Technique. Applying such a technique enables collaborating experts to share experience modify statements and re-asking to reach a final exact answer that could be generalized. The consensus achieved will help build knowledge and understanding of potential Dry Ports’ policies of the maritime transport sector. This research seeks to make an original contribution to knowledge by developing a structured framework to identify policy decisions for location and capacity of Dry Ports using a Delphi technique as a support tool for terminal managers and operators, port planners, policy makers, and investors in deciding decisions relevant to Dry Port investment.Arab Academy for science & Technology & Maritime Transpor

    Narrative motion on the two-dimensional plane: the “video-ization” of photography and characterization of reality

    "Art is not truth. Art is a lie that enables us to recognize truth" Pablo Picasso Time, as known to many, is an indispensable component of photography. Period(s) included in “single” photographs are usually and naturally much shorter than periods documented in video works. Yet, when it comes to combining photos taken at different times on one photographical surface, it becomes possible to see remnants of longer periods of time. Whatever method you use, the many traces left by different moments, lead to the positive notion of timelessness (lack of time dependence) due to the plural presences of time at once. This concept of timelessness sometimes carries the content of the photo to anonymity, the substance becomes multi-layered and hierarchy disappears. This paper focuses on creating photographical narratives within the two-dimensional world. The possibility of working in layers with transparency within the computer environment enables us to overlay succession of moments seized from time on top of each other, in order to create a storyline spread in time that is otherwise not possible to express in a single photograph, unless properly staged. Truth with the capital T is not taken as the departure point in this article; on the contrary, personal delineations of temporary yet experienced smaller realities is suggested

    Repeated excavations of buried utilities cause road congestion and maintenance conflicts. Besides, the interference of buried utilities in limited underground spaces does not meet the requirement of sustainable urban underground development. Multi-purpose utility tunnels (MUTs) integrate all utilities together in one tunnel and can be accessed by humans. MUTs reduce the excavation needs and costs and avoid the traffic congestion caused by excavations. MUTs also provide easy access for inspection and maintenance of all types of utilities inside the tunnel. MUTs have been in existence since the 19th century. MUTs in Europe and Japan were developed rapidly especially during the period 1961 to 2000. However, the development of new tunnels in recent years is limited and lacks long-term planning. MUT projects in North America are mainly in university campuses. On the other hand, China is making a big progress in MUT planning and construction because the Chinese government is taking MUT construction as an important urban infrastructure development. Focusing on China, the experience of MUT planning, construction and management in China can be very useful for other countries to examine the potential of MUTs as a sustainable option for future municipal asset rehabilitation projects. MUT planning is a key factor of urban underground space planning, which is an important part of urban planning. Previous research focused on MUT technologies; however, few researches focused on MUT planning. Location selection for MUTs is an important phase for MUT planning and it is complicated because it depends on several criteria, such as traffic volume and the density of the utilities. This research provides a general method for MUT location selection at different urban scales (e.g. street, district, borough) using Geographic Information System (GIS) spatial analysis. Multi-criteria decision making (MCDM) is used in this research to select potential MUT locations. The weights of the criteria are calculated using the Analytic Hierarchy Process (AHP) method. Several cases studies are used to demonstrate the feasibility of the proposed method. The specific objectives of the research are: (1) Review the history and recent development of MUTs in the world; (2) Carry out a cost analysis based on the project information to find out the relationship between cost and MUT cross section dimension, etc.; (3) Provide a general method for MUT location selection based on GIS spatial analysis. The conclusions of this research are as follows: (1) The experience of MUT planning and construction in Asia especially in China provides an alternative method for underground utilities, and is very useful for other countries to examine the feasibility of applying MUTs for future municipal asset rehabilitation projects. (2) Based on the AHP results, among the eight criteria used in the questionnaire, the most important criteria for MUT location selection are Annual Average Daily Traffic, utility density, expected number of excavations and future underground development projects. (3) The general method to select potential MUT locations using GIS spatial analysis is feasible
