A project delivery system (PDS) is the relationship and contractual structure between the owner and the contractors of a construction project; this system defines the roles and responsibilities of the participates involved in the project. Selecting a suitable PDS is one of the keys to achieve a construction project’s goals. PDS selection is a typical multi-attribute decision making problem that can...
It is convenient and useful to use the Monte Carlo simulation (MCS) in project schedule management, but at the same time, it provides very few management indexes for schedule risk analysis. Therefore, based on PERT network assumption, the shortcomings of current construction schedule management indexes are summarized and new construction schedule management index is put forward to calculate the criticality...
Quantifying and minimizing the risks associated with schedule and cost in hydropower construction are the main challenges for all parties involved. Under the impact of uncertain factors such as meteorological factor, there is a great uncertainty in the construction schedule of hydropower construction, accompanying with the occurrence of cost risk. This paper establishes the cost evaluation model using...
The premise and foundation of organization management begin with the assumption of humanity. Authors think that humanity is composed of inwardness, mental disposition and habit. Authors believe that humanity is a process of tending to “truthfulness, benevolence and forbearance”. On this basis, limitations and problems of “doctrine of good human nature”, “doctrine of evil human nature” and “doctrine...
Construction projects are initiated in complex and dynamic environments resulting in circumstances of high uncertainty and risk, which are compounded by demanding time constraints. This paper describes an application of Monte Carlo simulation method to consider and quantify uncertainty in construction scheduling. This paper points out the importance of the construction project scheduling risk analysis...
The correct choice of subcontractors (SCs) increases the overall success of a construction project for general contractors (GCs), but at present,there is not a uniform selection process or method. Bused on the characteristics of water conservancy and hydroelectric projects, from the perspective of construction GCs, evaluation index system of selecting SCs is designed ,the DEA cross-evaluation model...
In the parallel contracting mode with characteristics of single client and several contractors in construction phase, quality rank-order tournaments is analyzed whether it can incentive contractors to improve quality or not from the angle of client by applying the correlation theory and technique of Game theory and Economics of Information. Quality rank-order tournaments game model is established,...
Based on the optimization of transportation problem of Wulongquan Mine, genetic algorithm and Hopfield network are integrated for solving transportation problems of stripping rock. The optimization methods of genetic algorithm in artificial neural network weight, structure and algorithm are introduced; and GA-Hopfield network method is established for solving transportation problems. In GA-Hopfield...
