In this paper, the terminal air defense equipment system of systems (TADESoS) is studied as an example. The TADESoS is an important part of the joint air defense equipment system of systems, which mainly carries out the combat task to the low altitude flight target. The contribution rate evaluation of the TADESoS can provide theoretical basis for guiding the tactical plan of the TADESoS. Aiming at the problems existing in the evaluation of contribution rate of TADESoS, such as the difficulty of describing the structure of system of systems, the strong subjectivity of the evaluation method, and the difficulty of application of the evaluation results, this paper proposes a method of evaluating the contribution rate of the TADESoS based on fault tree. The method describes the structure of the TADESoS by multiattribute nodes. The probability of the top event is calculated by using the probability of the bottom event. Finally, based on the importance of the bottom event, the contribution rate evaluation model of the TADESoS is established, which solves the existing problems in the current research. Finally, the feasibility of the method is verified by an example.

Hierarchy Process

To solve technical and economic evaluation in the design stage of energy-saving buildings, rank the rationality and economic performance of energy-saving technologies under limited condition and provide basis for the amendment and optimization of energy-saving building schemes, technical and economic evaluation model which is according to matrix evaluation method and analytic hierarchy process is put forward and is used in an project to verify its feasibility. This model chooses energy saving rate, renewable energy contribution rate, add capital ratio and payback period of investment as indexes to describe, explain and evaluate the energy-saving technologies. And this model which can truly realize energy saving in the initial design is well adapted.

The construction of index system is the basis of equipment system contribution rate evaluation, and is also one of the main contents of equipment test and appraisal. This paper discusses the concept of systems contribution rate, introduces the evaluation process of system contribution rate of information system equipment, and gives the construction principles and ideas of information system equipment system contribution rate evaluation index system. Then, referring to the theory of operational loop, the evaluation index system of system contribution rate is given from the perspectives of system capability and system effectiveness. The evaluation index of this paper can provide decision support for the development of equipment planning system.

Shared Bicycle

Bicycle sharing is an effective way to solve the problem of residents’ last mile travel. Based on the SERVQUAL model. Build a service quality evaluation index system and evaluation model for shared bicycles. Taking Harbin’s bicycle as an example, the quantitative evaluation of the service quality of shared bicycles was carried out, and the existing problems of the service quality of shared bicycles were identified and targeted improvement strategies were proposed. The research results can provide a scientific basis for improving the quality of city shared bicycle services.
