In order to improve the productivity and reduce the cost of network management testing, it's quite necessary to develop a network management testing management system for domestic network management testing organizations. The paper analyzes limitations of foreign testing management systems and summarizes demands of network management testing management. Based on the concept of workflow, the paper designs a process of testing including testing plan, testing design, testing execution, testing conclusion, and describes them in detail. Finally, an application in China Mobile network management interface testing is given to demonstrate the value of the process.

This paper proposes a call admission control (CAC) scheme for heterogeneous wireless overlay networks (WONs) that combine the benefits of the three commonly used techniques- guard channel, buffer management and priority scheduling with fuzzy logic application. The simulation results show that the scheme is extremely efficient offering a high degree of quality of service (QoS).
Position location in three-dimensional (3-D) scenarios is studied in bearing-only location system. Through mathematical calculation in 2-D scenarios, the relationship between location accuracy and observation geometry...

We report on recent progress in developing a computer-aided nonlinear control system analysis and design environment based on sinusoidal-input describing function (SIDF) methods. Two major additions have been made to our CAD software for nonlinear controls during 1984: a simulation-based program for generating amplitude-dependent SIDF input/output models for nonlinear plants, and a frequency-domain nonlinear compensator design package. Both of these are described. This software can treat general nonlinear systems, with no restrictions as to system order, number of nonlinearities, configuration, or nonlinearity type. An overview of the application of this software to the design of controllers for a realistic, nonlinear model of an industrial robot was presented by the author in 1984, which serves to illustrate the use of these tools. Based on the software presented, the use of SIDF-based nonlinear control system analysis and design methods is substantially easier to carry out.

As highly reliable software is becoming an essential ingredient in many systems, the process of assuring reliability can be a time-consuming, costly process. One way to improve the efficiency of the quality assurance process is to target reliability Enhancement activities to those modules that are likely to have the most problems. within the field of softwareengineering, much research has been performed to allow! developers to identify fault-prone modules within a project. software qualify classification models can select the modules that are the most likely to contain faults so that reliability enhancement activities can be performed to lower the occurrences of software faults and errors. The contribution of this paper is the introduction of fuzzy logic combined with case-based reasoning to determine fault-prone modules given a set of software metrics. Although used in other fields, this is the first time, as far as we know, this type of modeling has been applied to software measurements for classifying fault-prone modules. Case-based reasoning is a technique that identifies similar cases from the past and uses their results to predict the category of the current cease. Fuzzy logic is a form of logic used in some systems in which variables can have degrees of truthfulness or falsehood represented by a range of values bettween 1 (true) and 0 (false). Combining these two techniques promises more robust, flexible and accurate models. In this paper, we describe this approach, apply if in a real-world case study, and discuss the results. The case study applied this approach to software quality modeling using data from a military command, control, and communications system. The Fuzzy Case-Based Reasoning model had an overall classification accuracy of more than 85 percent. This paper also discusses possible improvements and enhancements to the initial model that can be explored in the future.
