The incident response framework based on rule-based reasoning, case-based reasoning and Bayesian networks reasoning is presented. First, a freeway incident management system (RK-IMS) based on rule-based reasoning is developed and applied for incident management in the northern section of the Nanjing-Lianyunguang Freeway. Then, field data from the two-year long operations of the RK-IMS are analyzed. Representations of incident case structures and Bayesian networks(BNs) structures related to incident responses are deduced. Finally, the k-nearest neighbor (k-NN) algorithm is applied to calculate the similarities of the cases. The preplan generation and the control strategy by integrating the k-NN algorithm are also developed. The model is validated by using incident data of the year 2006 from the RK-IMS. The comparison results indicate that the proposed algorithm is accurate and reliable.展开更多

For the sake of developing the education of minority regions, the government adopted a lot of policies and measures, enacting special education policies is the important matter among them. The paper tries to take Du'an autonomous county, Guangxi autonomous region as a case to explore the problems in the executive condition of minority regions' special education policies, and gives the suggestion for the government to accelerate the education development of minority regions.展开更多

One of the most underrated Christmas Books, The Chimes (1844), proves to be an excellent example of a new fairy tale portraying the pervasion of two spheres: the realm of fantasy and the truth. The narrator exposes the correlation between the disturbing vision of the animated metropolis and the protagonist's hallucinatory fancy caused by his inner unrest and agitation, questioning the boundary between the dream and reality and the limits of perception. Despite the technical restraints of the seasonal miniature's construction, Dickens succeeded in capturing the hero's psychology and the spirit of the city through the medium of anthropomorphising the inanimate, employing the supernatural, and implementing powerful, semantically loaded images of London corresponding well with the protagonist's inner dilemmas. The narrative strategy balancing on the edge of dream and reality employed in the carol does not only expose the creative skills of the novelist, but also the potential of The Chimes as an embryonic novel展开更多

Ever since, there have been many different views over the origin of Japan's road toward war, which mostly concern with Japan's land policy. This paper holds that Japan's land policy was an evolving one and it transformed along the change of its supporters and implementers during different stages. It is mostly a contention about the different strategies on Manchuria and Mongol; the northward or the southward advance faction; the orientations of the radical military occupation or the moderate economic occupation. Interestingly, the development of Japan's postwar policy toward China, especially in the recent years, resembles the evolvement of Japan's land policy in the 19th century. They both show tendency from the economic effort to the military activity.展开更多

It is intangible and unstored, so service er-rors are not avoided. Once service errors appear, the first line staffs who keep di-rect touch with customers wil play an important role in service recovery. The staffs' negative emotions during the recovery service should be recovered by internal ser-vice recovery. In this paper, critical incident technique is applied to analyse the re-covery strategies expected by the first line staff and the internal service recovery strategies such as inspiring, authorization, training and psychology service are put forward. the strategy most expected by the staff is reward.展开更多

This paper elucidates a 2-step process for assigning probabilities to relevant events enabling a rational decision process to supersede decision choices based only on a gut feeling. After assessing probabilities the decision maker can confirm or reverse a gut feeling choice using expected values for each available act and traditional decision theory methodology. A simple example involving a buy now or buy later situation with market uncertainty illustrates the process for typical yes or no decisions.展开更多

So any disruption due to hazard event like earthquake can cause several direct and indirect damages. Direct damages can lead to the loss of equipments and qualified persons. Indirect damages can lead to inflation and loss of purchasing power. To deal with that situation, parameters that govern the vulnerability of building construction site have been identified. Using a MCDM (multiple criteria decision making) method, the priority order of these parameters has been set. Then a PVI (partial vulnerability index) and a GVI (global vulnerability index) are proposed. These indexes allow the classification of building construction sites according to their intrinsic vulnerability and seismic vulnerability respectively that is through the use of a given classification. Several Algerian building construction sites belonging to different seismic zones were considered in order to show the applicability of the method.展开更多

Hence, there is a need to develop algorithms which could be used by the consumers to schedule their loads. In this paper, load scheduling problem is formulated as a LCP (load commitment problem). The load model is general and can model atomic and non-atomic loads. Furthermore, it can also take into consideration the relative discomfort caused by delay in scheduling any load. For this purpose, a single parameter "uric" is introduced in the load model which captures the relative discomfort caused by delay in scheduling a particular load. Guidelines for choosing this parameter are given. All the other parameters of the proposed load model can be easily specified by the consumer. The paper shows that the general LCP can be viewed as multi-stage decision making problem or a MDP (Markov decision problem). RL (reinforcement learning) based algorithm is developed to solve this problem. The efficacy of the algorithm is investigated when the price of electricity is available in advance as well as for the case when it is random. The scalability of the approach is also investigated.展开更多
