This paper aims to give a comprehensive evaluation of equipment competitive development stage based on TOPSIS (Technique for Order Preference by Similarity to Solution) method and temporal operator. Competitive development of equipment is a new trend in the current national military-civilian integration strategy. In the past, the evaluation of equipment in the competitive development stage was mostly based on the historical information provided by suppliers, rather than on objective information. In the competitive development stage, equipment generally needs to do three major tests: Electromagnetic compatibility (EMC) test, environment test and reliability test. Therefore, experts can be used to objectively evaluate the test results. Then, the TOPSIS method and temporal operator are combined to process the evaluation information, and the comprehensive evaluation factor of the equipment is obtained by considering the cost of the equipment. Case study shows that the method has strong engineering practicability.
基于TOPSIS (Order Preference by Similarity to Solution)方法和时间算子对装备竞争发展阶段进行综合评价。装备竞争性发展是当前国家军民融合战略的新趋势。过去对处于竞争发展阶段的设备进行评价，大多是基于供应商提供的历史信息，而不是客观信息。在竞争性开发阶段，设备一般需要做三大测试:电磁兼容性(EMC)测试、环境测试和可靠性测试。因此，可以利用专家对试验结果进行客观评价。然后，结合TOPSIS法和时间算子对评价信息进行处理，在考虑设备成本的情况下得到设备的综合评价因子;实例分析表明，该方法具有较强的工程实用性。

The aero turboshaft engine is mainly used in helicopters. As a power unit that drives the rotor to generate lift and propulsion, it has been rapidly developed in recent years. When the power of the turboshaft engine meets the conditions of use, the key section temperature often exceeds the threshold. As another important indicator of engine performance, it will affect the safety of the whole machine. This situation has become the primary problem for the current turboshaft engine manufacturers. In this paper, based on the collected data of a certain type of turboshaft engines, according to the manufacturer’s suggestions, three component size variables are extracted firstly. They have been confirmed to affect the engine power and the key section temperature. Then, based on Bayesian network, the engine performance models are established for power and the key section temperature respectively. Finally, after validity verification, the production optimization table and transition optimization matrix are proposed. From them, some effective suggestions are also given for the optimization of engine performance.

With the development of technology, engineering systems are growing rapidly in their scale and complexity, which increases the severity of accidents and the urgency of risk assessment. Although lots of efforts have been done in risk analysis, their applications are limited when complex systems present the characteristic of multi-domain information synthesis and complete risk data is hard to obtain. To solve these problems, a risk assessment method based on DUCGs (Dynamical Uncertain Causality Graphs) is presented in this paper. With the advantage of DUCGs’ flexibility, high tolerance for information’s inaccuracy and incomplete information processing ability, the method based on DUCGs has lots of advantages: (1) Risk models in different fields can be established separately and the whole model can be obtained by merging the nodes shared by different models, which allow analysts to establish their risk model respectively. (2) Different from DBNs (Dynamic Bayesian Network) that need complete probability information, DUCGs only need probabilities related to risk status and they can alleviate the information incomplete problem to some extent. (3) The probability matrixes used in DUCGs are more consistent with people’s cognitive habits, which makes it friendlier for analysts and promotes the integration of expert experience and data. Finally, the practicality and superiority of DUCGs are verified in a case study.

The signatures and trend of degradation of 830 nm coaxial double heterojunction laser diode (DHLD) are studied by PSpice model simulation and accelerated degradation test. The relationships among temperature rise, degradation modes and signatures are revealed. Firstly, the mechanism of active region defect growth (ARDG) and cavity surface oxidation (CSO) are analyzed, and the causal relationship between temperature rise and CSO is revealed. Then, an equivalent circuit model of LD is constructed by PSpice software, and the simulation results show that the ARDG will cause the threshold current of P(I) curve to increase and the CSO will cause the slope to decrease. Finally, an accelerated degradation experimental platform is constructed, and the accelerated degradation tests are carried out on Sharp's 830 nm LD. The experimental results show that the temperature rise will cause the deterioration of CSO, but has no significant effect on ARDG.

Aeronautical parts, especially aircraft structures such as landing gear, are usually made of TC18 titanium alloys and other difficult-to-machine materials. The requirements for milling cutters are very high, so the price of cutters is relatively high. However, most of the blanks of aircraft structural parts are made of imported aluminium and titanium alloys, which have high cost. In order to ensure the processing accuracy, the cutting tools have to be replaced frequently. This will cause waste and increase the manufacturing cost because the actual life of the cutting tools is not fully utilized. At the same time, due to the closed high-end CNC milling machine or processing center processing, operators can not observe the actual cutting tool processing situation, can only judge the timing of tool change by experience, can not guarantee the high-quality and efficient processing of parts. So tool wear condition monitoring is a key technology in aircraft structural parts processing. Aiming at the situation that there is no theoretical data to guide tool changing in the process of high efficiency milling of aircraft structural parts, the tool wear monitoring system based on acoustic emission technology is designed according to the characteristics of acoustic emission signal. In this paper, the effects of spindle speed, feed speed, cutting width and tool wear on AE signal are studied by orthogonal experiment. The results show that tool wear has the greatest influence on the signal, followed by spindle speed and feed, and cutting width has the least influence on the signal.

Fault localization is possibly the most time consuming and tedious task in the process of program debugging. To alleviate this issue, we propose an ensemble of fault localization techniques. In our proposed ensemble technique, we have used DStar and Tarantula from the spectrum based fault localization family. Along with these two methods, BPNN and RBFNN are used from neural network based fault localization techniques. We also propose a novel CNN based fault localization method to strengthen the proposed ensemble classifier. We have proposed a new metric to measure the effectiveness of fault localization techniques more accurately. On an average, our proposed ensemble method is 16.76% to 38.47% more effective than the existing fault localization techniques.

Considering the complexity of the working conditions of the rescue manipulator arm and the safety of the rescue requirements, the structural reliability of the quick coupler that is important connecting component of the rescue manipulator arm is studied. Based on the stress-strength interference theory, a mathematical model of reliability analysis is established. The parameterized model of the key structure belonging to the quick coupler is established by using the APDL language. The randomness of variables such as critical dimensions, elastic modulus and load is fully considered. Using the PDS module of ANSYS, the Monte Carlo method is used to analyze the reliability of the key structure of the quick coupler. The stress probability distribution characteristics of the finite element analysis model are obtained. The research results are of great significance for verifying the rationality of the structural design of the quick coupler.

The Type-I censoring test has the advantage of time control which makes it widely used in the engineering practice. The outputs of the current Type-I censoring statistical algorithm are the total test time and the receiving number of failures. However, the total test time has already been settled by the test profile under many circumstances. Furthermore, the current Type-I censoring statistical algorithm is unable to evaluate the system reliability when the number of failure is zero during the system reliability test. Aiming at the problems above, a new Type-I censoring statistical algorithm was proposed to calculate the number of failures to receive the results of the reliability test considering the fixed total test time. And an evaluation method for zero-failure system reliability evaluation was developed. Then an assistant software was built to implement the algorithm. At last, two practical cases showed the importance of the receiving number of failures which should be calculated in the test design stage before the reliability test begins. And they also proved the new algorithm and the software is effective and feasible.
