The continuous operation mode of high equilibrium in the flow construction yields great benefits in lowering the cost and reducing the construction period as well as risks. The change of the construction period of any sub-construction will definitely exert a relatively great impact on the balanced construction of the project. Through the analysis of Monte Carlo simulation method (MC), the assurance...
Optimization of real estate portfolio is to select two or more different types of real estate for investment, and the previous models based on expected return-variance cannot meet the needs of the investors. Furthermore, the investors change their risk preference with the risk level. In this study, firstly, the semi-variance model of real estate investment portfolio based on risk preference coefficient...
The lowest tender price method in bidding of construction engineering is a mature and feasible method which conforms to market economy. The system environment and market economy are the foundation of this method through analysing it's implement environment. The essay put forward the implement countermeasures and five assuring measures about this method being practised in our country. The'power-money...
Along with the trend that emergency events frequently occur in the program management, it becomes significantly important to strengthen the program emergency management, and the scientific and reasonable resource allocation shall exert dual effects on the disposal of unexpected event. The paper proposes the process model of the program emergency management, analyzes the game between the program emergency...
In modern enterprise, project team has become a much more effective form for its flexible, problem-oriented and task-oriented. Knowledge sharing among teams plays a significant role in knowledge management of enterprise. Based on principal-agent theory, this paper explores the benefit game between enterprise and project team under information asymmetry condition, introduces both knowledge value and...
The previous approach solved the time-cost tradeoff problem without considering the impact of Internal Rate of Return (IRR) of the project. The present paper incorporates it into project time-cost tradeoff for hydropower construction. The research on performance and the tradeoffs between time-cost and performance is of significance when the lasting time of the construction is uncertain. It is also...
The time-cost optimization (TCO) problem is a multiobjective problem, which attempts to strike a balance between resource allocation costs and project schedule duration. In this paper, a self-adaptive ant colony optimization (SACO) with changing parameters based on information entropy has been employed to model time-cost optimization problem, which overcome the intrinsic weakness of premature of the...
