Resource scheduling and planning for tunneling with a new resource model of the Decision Aids for Tunneling (DAT)

Resource scheduling and planning are the strategies required to determine the sequence of activities and resource allocation during tunnel construction. Resource scheduling and planning have been implemented in a new resource model of the Decision Aids for Tunneling (DAT), which are a computer based tool used to simulate tunnel construction. Tunneling plans obtained with the new resource model of the DAT take into account the technical precedence of activities, the resource/space availability, the dynamic status of the process, and the work continuity. In particular, the new resource model of the DAT can provide the optimal tunneling plan, which produces the shortest construction time and the smallest construction cost, and satisfies the special characteristics of tunnel construction such as excavation methods, distance requirements between the headings, and preempting activities (e.g., blasting).The paper attempts to contribute to both theory and practice: Optimization of the construction process considering time, cost and resources is particularly complicated in tunneling where activities and resource availability have to be appropriately sequenced and interference has to be avoided. The paper addresses this fundamental problem with the development of different schematic tunneling plans that consider the relevant activities and optimizes them with regard to overall cost and time, also considering uncertainties. Equally important is to make the theoretical development practically useable. This is done through implementation of the resource optimization in the DAT and, very importantly, by demonstrating the practical use with an application to a real tunnel case.     

Building education for the next industrial revolution: teaching and learning environmental literacy for the building professions

Resource efficient design and construction, i.e. doing more with less, contributes to decreasing the negative environmental implications of resource consumption. However, the environmental effects of buildings arise from the combination of many design and management decisions, and good environmental design and construction can avoid more than just the damage that flows from resource use. It is therefore important that students of building professions learn how the many decisions they make can help create ecology sustaining buildings, and this awareness begins in the classroom. This paper proposes a model for teaching and learning environmental literacy for tertiary students of building professions. It also argues that, in comparison with a well recognized theory for language learning, some of the conditions required for learning environmental literacy may not be present in Australian tertiary institutions. This work was commissioned for the Australian Council of Building Design Professions for the Environment Design Guide and funded by EcoRecycle Victoria.

Resource constrained project scheduling using simulation

Resource allocation is one of the most important issues of construction management. Two problems of resource allocation are of concern: resource levelling and resource scheduling. Traditionally, the resource scheduling problem is solved using either heuristic methods or optimization techniques. When heuristic methods are used, resource scheduling is treated as a subsequent problem for the CPM analysis. In this paper, the resource scheduling problem is handled using simulation, where logic dependence and resource availability limits are considered simultaneously during the time scheduling process. Simulation is applied to the resource scheduling problem at the project level. A simulation system called SIRBUS is used to schedule construction projects under resource constraints. Constant resource demand of activities is assumed, and the activity once started cannot be interrupted. Six example projects previously solved by different heuristic methods are re-solved using simulation. The results are compared with the latest heuristic models: current float technique and ranked positional weight method. In addition to the advantage that resource availability is considered during time scheduling as a starting point, which is an apparent feature of simulation, SIRBUS gives good results compared with existing heuristic methods.     

Smart Grid in China: a promising solution to China’s energy and environmental issues

Smart Grid presages an advanced power grid that revolutionizes the century-old traditional power grid and the way mankind uses energy. In China, the pressure on the current grid exerted by growing demand, environmental issues and the unbalanced energy use structure makes the transition to a ‘smarter’ and ‘cleaner’ grid inevitable. This paper firstly contrasts the concepts and research priorities of Smart Grid of China and other developed countries; then turns to the situation of Chinese energy and power use. China has the largest generating capacity, 79% of which is coal-fired plants. And China is also the largest carbon emitter in the world. Despite the challenges, China is also the most promising market for Smart Grid. The components of Smart Grid, especially the development of renewable energy, electric vehicles and smart substation are reinforced in the Chinese 12th Five-Year Plan (2011–2015). The paper examines also efforts by government, power utilities and research institutes. The paper concludes that developing Smart Grid will be beneficial both to China and the world.

A genetic-algorithm-based resource-constrained construction scheduling system

Resources for construction activities are limited in the real construction world. To avoid waste and shortage of resources on a construction jobsite, scheduling must include resource allocation. A new resourceconstrained construction scheduling system is proposed in this paper. A GA-based searching technique is adopted in the system. In this paper, new GA crossover and mutation operators, UX3 and UM3, are presented. These new operators overcome the drawback of traditional GA operators for sequencing problems. The system effectively can provide the optimal combination of construction duration, resource quantities and minimum project duration under the constraint of limited resources.
