基于线形图的地铁工程4D进度控制系统研究与应用

地铁工程涉及专业广、建设周期长、内容复杂,且属于线形工程,采用CPM方法编制进度计划,会导致进度计划非常的复杂、难以直观反映任务的地理位置及工作面搭接关系和施工过程中的空间冲突问题。提出一种基于线形图的地铁工程进度管理方法,形象地显示地铁工程的每一个任务的地理位置和耗费的时间,以及同一工作面上不同任务的位置搭接关系。并通过构建基于线形图的进度冲突识别算法,实时检测当前进度计划可能存在的空间冲突问题。在此基础上,通过数据库将进度计划与3D/CAD模型建立关联关系,构建4D可视化进度管理系统,直观地反映施工过程中的空间冲突问题。本系统在某地铁工程中成功应用,及时发现了施工计划中的空间冲突问题,实现了对项目实时、精准的控制,提升了地铁工程进度管理的水平,提高了投资效益。

VR-based planning of construction site activities

This paper presents an approach to the integration of site-related activities into the planning and scheduling of the entire construction project. The paper starts by briefly reviewing some common methods used by construction firms in the planning and scheduling of site activities. Next follows a discussion of current research efforts concerned with the modelling of site-related procedures. Then a virtual-reality-based model is proposed, which uses both knowledge-based simulation of the work progress and visualisation capabilities, to achieve the desired integration. Finally the prototype system is described and its potential is demonstrated through several examples.

Defining coherence for landscape planning and management: a regional landscape strategy for North West England

The range of environmental activity in the North West of England is as diverse as its landscapes. These embrace some of the finest, but also some of the most degraded, landscapes in the UK; to date however, there has been no overall co‐ordination of initiatives aimed at their protection and rehabilitation. The emergence of regional planning guidance, a regional economic strategy and the agenda of sustainable development demands a more integrative, strategic approach to environmental action. This paper details the development of a regional landscape strategy which seeks to provide the connection between action at the regional and the neighbourhood levels through the co‐ordination, reinforcement and innovation of environmental activity. The regional landscape strategy provides a focus around which the interests of public, private and voluntary bodies can coalesce and a medium for the articulation of policy aspirations relating to the sustainable planning and management of landscapes.

A decision-making system for construction site layout planning

A decision-making system, which consists of input, design, evaluation and selection, and output stages, is proposed to solve dynamic, multi-objective and unequal-area construction site layout planning (CSLP) problem. In the input stage, the multiple objectives, schedule planning and site condition are determined. In the design stage, two mathematical optimization models max-min ant system (MMAS) and modified Pareto-based ant colony optimization (ACO) algorithm are employed to solve single objective optimization (SOO) and multi-objective optimization (MOO) problem respectively. In the evaluation and selection stage, the intuitionistic fuzzy TOPSIS method is used to evaluate and select the best layout plan among the generated layout alternatives from the design stage. The performance of the proposed decision-making system, which was verified by a residential building project, shall assist the practitioners in the construction industry to deliver construction projects in a more efficient and effective manner, and thus construction costs could be reduced significantly.

An object-oriented model for planning and control of housing construction

A practical object-oriented model for the planning and control of housing construction is presented that can generate efficient schedules and determine the time and cost performance of a housing project at three levels: (i) entire project, (ii) particular housing unit and (iii) an individual subcontractor. The model comprises five major components: (1) input module, (2) scheduling module, (3) database module, (4) control module and (5) reports module, and incorporates 18 classes that are designed to address the main requirements in planning and control of housing construction. The model is implemented as a user-friendly prototype software system using Visual C++ 6.0 and Microsoft Foundation Class (MFC). The prototype software is named ‘Residential Planner’, and runs in Windows 2000 and NT. An example of an application is analysed to illus8 trate the use of the developed model and demonstrate its practical features.     

Optimizing construction planning schedules by virtual prototyping enabled resource analysis

The inherent uncertainty and complexity of construction work make construction planning a particularly difficult task for project managers due to the need to anticipate and visualize likely future events. Conventional computer-assisted technology can help but is often limited to the constructability issues involved. Virtual prototyping, however, offers an improved method through the visualization of construction activities by computer simulation — enabling a range of ‘what-if’ questions to be asked and their implications on the total project to be investigated.This paper describes the use of virtual prototyping to optimize construction planning schedules by analyzing resource allocation and planning with integrated construction models, resource models, construction planning schedules and site-layout plans. A real-life case study is presented that demonstrates the use of a virtual prototyping enabled resource analysis to reallocate space, logistic on access road and arrange tower cranes to achieve a 6-day floor construction cycle.     

A linear programming model for cash flow management in the Brazilian construction industry

A linear programming model has been developed for optimal cash flow management addressing specific cash flow issues related to the construction industry. These include typical financial transactions, possible delays on payments, use of available credit lines, effect of changing interest rates, and budget constraints that often occur in the construction industry. A small size project from the Brazilian construction industry is provided as a case study, aiming at evaluating the potential benefits from using the model. Different changes to the basic structure of the model allow and establish the consistency of the results. Alternative formulations are suggested to deal with uncertainties, longer planning horizons, and multiple subcontractors and suppliers. In addition to the tangible financial earnings derived from the optimization process, the simple structure of the model, as a network flow and corresponding equations, provides much visual insight concerning the relationships between the external inputs and the variables of the problem. Optimal results have yet to be achieved in a real life situation, but a better view of whole cash flow management is provided when using the model.
