Improved Ant Colony Algorithm for Vehicle Scheduling Problem in Airport Ground Service Support

Support vehicles are part of the main body of airport ground operations,and their scheduling efficiency directly impacts flight delays.A mathematical model is constructed and the responsiveness of support vehicles for current operational demands is proposed to study optimization algorithms for vehicle scheduling.The model is based on the constraint relationship of the initial operation time,time window,and gate position distribution,which gives an improvement to the ant colony algorithm(ACO).The impacts of the improved ACO as used for support vehicle optimization are compared and analyzed.The results show that the scheduling scheme of refueling trucks based on the improved ACO can reduce flight delays caused by refueling operations by 56.87%,indicating the improved ACO can improve support vehicle scheduling.Besides,the improved ACO can jump out of local optima,which can balance the working time of refueling trucks.This research optimizes the scheduling scheme of support vehicles under the existing conditions of airports,which has practical significance to fully utilize ground service resources,improve the efficiency of airport ground operations,and effectively reduce flight delays caused by ground service support.

Light-Weighted Decision Support Framework for Selecting Cloud Service Providers

Multi-criteria decision making(MCDM)is a technique used to achieve better outcomes for some complex business-related problems,whereby the selection of the best alternative can be made in as many cases as possible.This paper proposes a model,the multi-criteria decision support method,that allows both service providers and consumers to maximize their profits while preserving the best matching process for resource allocation and task scheduling.The increasing number of service providers with different service provision capabilities creates an issue for consumers seeking to select the best service provider.Each consumer seeks a service provider based on various preferences,such as price,service quality,and time to complete the tasks.In the literature,the problem is viewed from different perspectives,such as investigating how to enhance task scheduling and the resource allocation process,improve consumers’trust,and deal with network problems.This paper offers a novel model that considers the preferences of both service providers and consumers to find the best available service provider for each consumer.First,the model adopts the best-worst method(BWM)to gather and prioritize tasks based on consumers’and service providers’preferences.Then,the model calculates and matches similarities between the sets of tasks from the consumer’s side with the sets of tasks from the provider’s side to select the best service provider for each consumer using the two proposed algorithms.The complexity of the two algorithms is found to be O(n3).

Information Security Service Support-Helping End-Users Cope with Security

Organizations implement an information security program for the protection of their information assets. The success of such a program depends primarily on the effective implementation and execution of associated information security policies and controls. These policies and controls depend directly upon the resultant behavior and actions of end-users. Hence, end-users play a critical role in the effective implementation and running of an information security program in any organization. However, end-users are often unable to navigate and comprehend the various policies, controls and associated issues. Support to end-users is therefore a vital element, but is often neglected by present information security management systems. In the service industry, support to customers is established as an important determinant of customer perceived service quality. This paper applies the same philosophy to provide support to end-users, who are the customers of the Information Security Service.

School Support Services Model for Students With Disabilities in General Education Classrooms： Using Data From the Special Needs Education Longitudinal Study in Taiwan

The purposes of this study were to establish a school support service model for students with disabilities in general classroom, and to explore the current status of school support services provided for students with disabilities in preschools, primary, and junior high schools. Therefore, this study used data from the Special Needs Education Longitudinal Study in Taiwan, collected in the 2007-2008 academic year. There were 2,924 students with disabilities selected in the study who were placed in general classrooms; 855 were in preschool, 1,079 were in primary school and 990 were in junior high school. The questionnaires in the database were answered by their teachers. The results of this study are listed, as follows： In terms of the school support service model for students with disabilities in the three stages of education, adjustment in teaching accounts for 1-15% of the explanatory power regarding the overall model, while support services account for 63-85%, which peak in junior high schools. Secondly, itinerant teachers are found to be the most important human resource in preschools. For primary and junior high schools, parents and special education teachers are the more prevalent influences. The more common school support services are tuition refunds, itinerant services, adjustments in examinations, and scholarships.

Medical care service model combined with support policy development and theoretical research

China has entered the aging society, on the one hand, the number of elderly people in the gradual increase in the number of the corresponding oldest old, disabled elderly, and other semi-disabled elderly is also increasing; on the other hand, family pension function is weakening.
