For an urban traveler using headway-based bus services, this paper concerns the itinerary planning problem with deadline under vehicular travel time and transfer waiting time uncertainties. An earliness ratio is proposed to practically specify the travel time budget, which is given by a traveler determined by his / her conservatism level. Both the risk and ambiguity of each uncertain arc travel times...
Grey DEA model is a non-deterministic efficiency measurement model on basis of the concept of relative efficiency used to evaluate and make decision-making with uncertain information. In view of this, grey DEA model is used to make performance evaluation on university S&T intermediary agencies according to the index data from other researches, and then some insightful results are discussed.
Taking the NCEP/NCAR monthly reanalysis data from 1948 to 2005 as the observation field, the simulation abilities of the BCC_CSM model for height field over China, the western Pacific subtropical highs, the South Asia high, and the East Asia major trough are tested by using the standardized Root Mean Square Error (RMSE), correlation coefficient, kriging interpolation methods. Results show that: (1)...
This paper studies the influence of intake initial conditions on high density - low temperature diesel performance with simulation analysis of software FIRE and orthogonal test method. We perform simulation on the 4100 diesel, and the result shows that, the most notable influence on the comprehensive performance of diesel is EGR, followed by the intake pressure, and the third is the intake temperature...
Empirical research aimed to explore and validate the scientific nature and effectiveness of performance evaluation index system of the University which is established by deduction and scientific testing. Based on a university, we selected part of experts to score by using the questionnaire, using fuzzy analytic hierarchy process to establish comprehensive evaluation of the mathematical model, drawing...
The research performance of universities in China is evaluated in this study from the global perspective. Based on the Essential Science Indicators (ESI) database, this research mainly concerns the academic output in overall publication activity and the influential strength of certain disciplines of selected universities. Different types of bibliometric methods are applied in this study, including...
