An investigation into the main information dimensions of corporate real estate management

Abstract: The fragmentation of the construction and real estate sectors, and the information intensive character of their activities, makes it very difficult to select, store and transfer relevant information among its members. The volume and diversity of data in these sectors have been a hindrance for developing effective, integrated and standardised information systems for construction, building and real estate management. To overcome these problems at the level of strategic management of corporate real estate, a research was set to elicit the main information dimensions, or the main concerns, within the area. This research used as paradigms models that succeeded on defining and using the main dimensions of a particular subject matter, facilitating communications, decision-support and learning processes. Examples of these paradigms are the main factors of production in the theory of capital in economics, the balanced scorecard and the critical success factors in organisational management, the three dimensions in project management and Pena's (1987) main concerns for programming in architecture. The research consisted of a content analysis of seventy corporate real estate management (CREM) models used in industry and academia eliciting the main features (concepts, tools, techniques, methods) quoted on these models. Using classification techniques and supported by a literature review and expert interviews, these features were classified according to their nature, similarities and origin. The main dimensions resulting from this classification system provided the main information dimensions in CREM. These dimensions are financial, physical and human, each one divided in three classes, respectively. The financial dimension is divided in the classes rentability, business information and intelligence. The physical dimension is divided in the classes data, management and diagnosis. Finally, the human dimension is divided in the classes organisation, occupancy and customer. Examples of uses of the CREM framework are given.

Development of Dynamic Planning and Control Methodology (DPM): based on the user-defi ned dynamic modeling approach

Abstract: CPM-based scheduling methods have been most widely used in the planning and control of construction projects. However, their usefulness has been often questioned, particularly when a project is heavily constrained by either time or resources. This is mainly because those CPM-based methods lack the mechanism to effectively formulate construction plans and evaluate feedback effects on the construction performance. As an effort to address this issue, the Dynamic Planning and Control Methodology (DPM) has been developed by integrating the CPM-based network scheduling concept and the simulation approach. To be used as a standalone planning and control tool, DPM adopts the user-defi ed dynamic modeling approach, which allows construction planners to defi ne contents of pre-structured models by setting the values of model parameters. Having the ability to simulate the dynamic state of construction with the required fl exibility, DPM aims to help prepare a robust construction plan against uncertainties. Particularly, DPM focuses on construction feedbacks in dealing with indirect and unanticipated events that might occur during construction. As examined in a case study with bridge construction projects, the use of DPM would help ensure that construction projects could be delivered in time without driving up costs by enhancing planning and control capabilities.

A geographically distributed multi-reasoning mechanism for change negotiation management of large scale engineering systems

Abstract: In large scale engineering projects, no design process can perfectly forecast every aspect of detailed project conditions. Sometimes oversights, mistakes or changes in the design must be corrected, and sometimes completely external factors also force changes in the situation. The basis for most changes is some form of conflict. In addition, the negotiation of such conflicts frequently results in suboptimal, inefficient agreements leading negotiators to believe that they could have reached other settlements.This paper presents the preliminary results of a research that explores mechanisms to provide a model for this negotiation process and applies automated multi- reasoning and learning mechanisms to the same. The ultimate goal of this research is to provide negotiators with precedence information to help them reason in a co-operative way assisting in the effort to seek "all-gain" rather than "win-lose" solutions.
