Flexible space-sharing strategy for storage yard management in a transshipment hub port

In this paper, a storage yard planning problem is studied for a transshipment port with limited space and high-throughput level. Generally, the consignment strategy is used in the yard for a transshipment port, where containers to the same destination vessel are stored together. This is to facilitate faster loading process as it reduces reshuffles as well as long distance movements of yard cranes. However, the consignment strategy is known to be inefficient in space utilization since each storage location must be dedicated to a particular vessel. To improve the space utilization while retaining the advantage of consignment, a new approach named the “flexible space-sharing strategy” is proposed. The idea is that the container space can be shared by two different vessels as long as their containers do not occupy the space at the same time. This strategy allows the same storage location to be reserved for two vessels. The amount of space will only be allocated to a specific vessel on the arrival of corresponding containers. By controlling where to stack the containers in the storage locations, the containers to each vessel are not mixed and the consignment feature can be preserved. This strategy is first formulated as a mixed integer program (MIP). As the MIP model has a block diagonal structure, we develop a search algorithm which combines MIP and heuristics to find the solution. The numerical experiments show that the “flexible space-sharing strategy” can handle much more containers within the same storage space compared with the “non-sharing strategy”.     

Short-term space allocation for storage yard management in a transshipment hub port

In transshipment ports, the containers to the same destination vessel are usually stored together to facilitate the loading process, which is called the “consignment”. During operation, the actual containers that will come in are only known for a short period in advance. Thus, short-term space allocation is needed to assign incoming containers taking into account the transporting vehicles, yard cranes and storage space. Currently, the space is allocated based on the experience of port operators. To balance the current and future impacts of short-term planning, we develop a systematic method called “space allocation given long-term plan (SALP)”. The corresponding MIP model is formulated to utilize not only the short-term information, which includes the existing containers and the actual incoming containers, but also the given long-term plan, which provides a forecast of future requirements. The SALP method is evaluated under two storage strategies to achieve consignment, namely, the “non-sharing strategy” and the “flexible space-sharing strategy”. The numerical experiments show that the SALP method improves operational efficiency, but its performance is affected by the portion of long-term plan under consideration. The SALP method performs well under both storage strategies when space is sufficient. However, the performance under the “flexible space-sharing strategy” is better than the “non-sharing strategy” when space is tight.

Development and management of a radon assessment strategy suitable for underground railway tunnelling projects

The construction of underground tunnels through radon-bearing rock poses a radiation health risk to tunnelling workers from exposure to radon gas and its radioactive decay products. This paper presents the development and practical application of a radon assessment strategy suitable for the measurement of radon in tunnelling work environments in Hong Kong. The assessment strategy was successfully evaluated on a number of underground railway tunnelling projects over a 3 y period. Radon measurements were undertaken using a combination of portable radon measurement equipment and track etch detectors (TEDs) deployed throughout the tunnels. The radon gas monitoring results were used to confirm that ventilation rates were adequate or identified, at an early stage, when further action to reduce radon levels was required. Exposure dose estimates based on the TED results showed that the exposure of tunnel workers to radon did not exceed 3 mSv per annum for the duration of each project.     

Evaluating management of large,complex projects: A framework for analysis

Increasingly owners and managers of large, complex projects are challenged in law suits and regulatory proceedings to justify their decisions. These challenges often question the prudence or reasonableness of management actions on a project costing substantially more than its original estimate. Frequently these attacks criticize decisions made years earlier by project owners or managers. This article describes a framework for evaluating management prudence based on the author's 20 years of research and personal experience with large, complex projects. The framework distinguishes between evaluations to determine prudent/imprudent management, and conventional “lessons learned” management audits. The author concludes that, while hindsight knowledge is a useful ingredient in “lessons learned” audits, it usually provides misleading signals for a management audit to determine prudence or imprudence. He concludes that any finding of management imprudence must meet the eight criteria described in the framework.     

Environmental assessment for non-prescribed infrastructure development projects: a case study in Bangkok Metropolitan

Rapid urbanization and urban growth have caused serious environmental problems in most cities of developing countries. Many infrastructure projects on varying scales have been implemented to meet the growing demands of such cities, but only a few are subjected to environmental impact assessment as part of the project approval process. In an attempt to justify environmental assessment (EA) for all infrastructure development projects (IDPs), irrespective of their scales, this paper investigates the environmental effects of large, medium and small IDPs implemented in urban fringe areas to understand and compare the nature of their impacts. The survey results show that respondents' perceptions of physical environment pertaining to air quality and noise were similar regardless of the scale of the project. However, in terms of vibration, surface water quality and ground water quality, the respondents' perceptions differed between large projects and small or medium projects. In order to avoid such negative impacts from IDPs in the future, this study proposes a mechanism for integrating EA into the planning and development control processes of local authorities.

Project network-oriented materials management policy for complex projects: a Fuzzy Set Theoretic approach

This work devises a materials management policy integrated with project network characteristics of complex projects. It proposes a relative quantitative measure, overall criticality (OC), for prioritisation of items based on penalty incurred due to their non-availability. In complex projects, practicing managers find it difficult to measure OC of items because of the subjective factors and intractable nature of penalties involved. However, using their experience, they can linguistically identify the antecedents and relate them to consequent OC. This work adopts Fuzzy Set Theory to capture managerial tacit knowledge which provides them enough flexibility to provide information in real form. Computed OC values can be used for items prioritisation and as shortage cost coefficient in inventory models. The revised materials management policy was applied to a shipbuilding project. OC values were analysed to justify the importance of incorporating project network characteristics and potential cost savings were calculated.     

Environmental impact assessment (EIA) screening and scoping of extraterrestrial exploration and development projects

Numerous space missions are planned by government agencies and private companies, with objectives including scientific research, prospecting for and mining resources, and establishing human settlements. These projects have potential to affect the extraterrestrial environment. Environmental impact assessment (EIA) is an important tool for assessing the potential impact of projects on Earth’s environment. However, the legal requirements to undertake EIA for extraterrestrial projects are limited and most EIAs that have been conducted have not considered impacts beyond Earth’s atmosphere. Technical barriers to extraterrestrial EIA also need to be overcome, including a lack of guidelines and methodologies. This paper addresses the latter issue by identifying the extraterrestrial impacts that may arise from space projects and relating them to the environmental topic areas in the European EIA Directive. An example is then provided of how EIA screening and scoping can be undertaken for the extraterrestrial elements of space projects, using six scenarios. Effective EIA screening and scoping is key to deciding whether EIA is required and if so which topic areas should be included.

Project planning and risk management as a success factor for IT projects in agricultural schools in Serbia

Enterprises and business systems are introducing modern information and communication technologies into their organizations to improve their business processes and gain a competitive advantage. Theoretical research, as well as research carried out in practice, unambiguously indicate that companies take this step without the necessary professional analysis of business processes and insufficient knowledge of the project management methodology. Also, in this area there is a lack of adequate literature, especially in the field of information technology (IT) project management. This paper provides a new approach for research in the field of project management throughout a studious analysis of risk management in IT projects. To confirm hypotheses, this paper examines and outlines concrete IT management solutions in business systems with emphasis on education organizations, which leads to business improvement and achievement of positive business results.
