Finally, a number of important issues in the application of agent-based approaches in construction (e.g., potential application areas, development method, and difficulties) are outlined and further analysed.
Due to the calculated error of the lost gas in the direct method and difficulties in accurately measuring the gas pressure used to calculate the gas content in the indirect method, the accurate determination of gas content remains a difficult problem.
Two examples including one three-story, two bays moment frame and one ten-story, two-bay frame are used to illustrate the efficiency and accuracy of the method and difficulties of the FDM for nonlinear sensitivity analysis (NSA) of RCMRF are discussed.
Questions regarding the main epidemiologic studies used in assessing dioxin risk relate to the method and difficulty of measuring and reconstructing exposure, the high levels of exposure, and the lack of quantification of potential exposure to other highly toxic compounds (Crump et al. 2003; Starr 2003).
While fragment analysis methods such as pulsed-field gel electrophoresis (PFGE) are used to trace the sources of contamination for this bacterium, some drawbacks have been identified, namely the complexity of the methods and the difficulty of making data comparisons.
I discuss a range of probabilistic and nonprobabilistic methods, and the difficulty of accounting for ignorance in management decisions.
First, due to the complexity of the measurement methods and the difficulty in finding appropriate and willing participants, it is a small study with limited power.
We also were interested determine to what extent the cross-validation classification performance is influenced by different data-resampling methods and the difficulty of the classification problem.
In such cases, it is difficult to precisely identify differentially expressed genes using traditional statistical methods, and this difficulty is exacerbated when the sample size is small.
