Pub/Sub services in the cloud are intended to achieve high performance and high scalability. The challenge comes from how to deal with the potential wide variation in workloads. The paper constructs a content-based Pub/Sub service named OPS4Cloud on the top of cloud infrastructure from scratch. OPS4Cloud manages its brokers by regions and presents a VM-based region adjustment strategy. It builds two-level...
This paper intends to investigate a comprehensive evaluation method for material purchasers' performance with the consideration of the existing corruption. Firstly, the paper puts forward the multi-level evaluation index system of purchasers based on the objective of corporation strategy. After indexes' weights are determined by using AHP, a multi-level gray evaluation model for material purchaser's...
The two sets of management systems formed by the project team built under the matrix organization structure, vertically and horizontally are not only to the benefit of the centralization of leadership, but also to the cooperation and complement of team members. The key of the problem is how to choose the suitable members for the project team according to the needs of different projects. Based on this,...
Cross-coupled synchronization controller design method based on quantitative feedback theory (QFT) is proposed to deal with dual hydraulic motor driven problem of flight simulator. The method uses frequency characteristic sets(plant templates) of two motors with given operating point extent as its system plant, and utilizes QFT SISO controller design process and MIMO stability conditions to synthesize...
Sickbed arrangement is an important part of daily management in the hospital. Since the service time for different type of patients varies, the queuing system here, with multi-random input flow, can not be solved accurately by using classical queuing theory. Based on the analysis of patient information, we apply the simulation method into the sickbed arrangement system, and take the average waiting...
This paper selected appropriate indexes to evaluate the relative efficiency of health care systems of 14 nations including China and the United States with DEA-CCR model, and found that the Chinese health care system is effective. Therefore, this paper classified these systems into 4 categories to analyze their characteristics, and put forward reform advices focused on Chinese health care system.
It is an effective evaluation method of multi-objective optimization in engineering network planning put forward in this paper. The optimization of schedule control subsystem, cost control subsystem, resource control subsystem and quality control subsystem is based on the technology of engineering network planning. According to the principle of system coordinating control, the model of coordinating...
Performance assessment is a core in human recourse management of enterprises and institutions, and in order to optimize allocation of human resource, it is important to give appropriate weight to each evaluating index. This paper introduces the thought of hierarchy into the use of rough set theory, and figures out the optimal weight of each index from the objective data.
By analyzing the factors which have impact on how the hospital arrange its sickbeds, this paper gives a evaluation index system about arranging the sickbeds and a evaluation model that based on the overall satisfaction of the patients and the hospital. From the perspective of patients, we consider their time, cost and the therapeutic effect, while from the viewpoint of the hospital, the analysis incorporates...
The topic of tuition fees has recently sparked heated discussions in various media. Based on China's national conditions, this article collected elevant data, such as national student average funding, training costs, household disposable income and did the quantitative analysis for tuition standards of several types of schools, then built a Multi-level fuzzy evaluation model, which regarded the tuition...
