Research on Enterprise Employee Performance Appraisal Management System Based on CS Architecture

Aiming at the problems of poor system throughput and poor performance appraisal indicators in traditional enterprise employee performance appraisal management systems, a corporate employee performance appraisal management system based on the CS architecture was designed. Firstly, the system architecture of performance appraisal system is built, the system logical architecture design is determined, and the functional modules of the appraisal management system are analyzed. Then, the influencing factors of employee performance appraisal management system are analyzed through the evaluation constraint parameters, and the quantitative regression analysis model of enterprise employee performance appraisal management is constructed to realize the design of enterprise employee performance management software. Finally, the evaluation management system database was built to realize the enterprise employee performance evaluation system’s design based on CS architecture. The experimental results show that this system can improve the throughput of the employee performance appraisal management system and the rationality of enterprise employee appraisal standards. It plays an important role in enterprise employee performance appraisal management.

Information System Services Generation of Business Services Specification and Based on a System-of-Services Logical Architecture Pattern

The generation and design of the service architecture of an information system is complex. It depends more on the vision of the service than on the vision of the service inside an information system. An information system is indeed a system of services that can contain thousands of services. The lack of consideration of constraints imposed by the information system makes it difficult to reuse these services. Another strong constraint is that an information system service must support a business service. The proposed approach allows information system services to be generated in accordance with the business services specification and their logical architecture to be automatically designed by respecting a logical architecture pattern of the system-of-services. An information system services generation algorithm allows being consistent with the logical architecture pattern during this generation. The definition of coherence and coupling properties makes it possible to evaluate the relevancy of the system-of-services. A use case shows the value of these properties in making the logical architecture of the service system more relevant to business services.

Availability Assessment of IMA System Based on Model-Based Safety Analysis Using AltaRica 3.0

The integrated modular avionics (IMA) system is widely used in all classes of aircraft as a result of its high functional integration and resource utilization in developing advanced avionics systems. However, a series of challenges related to safety assessment exist in the background of the logical architecture for multi-message interactions of the IMA system. Traditional safety assessment methods are mainly based on engineering experience, and are difficult to reuse, incomplete, and even error-prone. Here we propose a method to assess the availability of the IMA system based on the thinking of model-based safety analysis. To aid the proposed method, we implement a tool to generate a AltaRica 3.0 file used to assess the IMA system model. The simulation results show that the proposed method makes the availability assessment fast, efficient, and effective. Moreover, we apply this method to the modification analysis of the IMA system under the condition of satisfying the safety requirement. Our study can enhance the safety assessment of safety-critical systems effectively, assist the design of IMA systems, and reduce the amount of errors during the programming process of the safety model.

Concept of implementation of the entrance payment system to the city for the example of district in Warsaw

Increasing traffic causes not only communication difficulties, but also contributes to increasing air pollution and increasing noise levels. In an urban environment it is quite cumbersome, compact buildings, sometimes the proximity of industrial plants, contributes to the intensification of this phenomenon. By establishing a paid entry to selected areas, thus introducing zones covering the district, center or the whole city, it is possible to significantly influence the quality of the transport network in this area. The paper analyzes the EU regulations regarding emission limit values for vehicles sold in its area. There are also discussed threats resulting from excessive traffic in the city, such as air pollution, on the example of the city of Warsaw. The effects of excessive air pollution are also presented. The paper presents the concept of a system of paid entry to the city, based on the example of the Warsaw district of Śródmieście. The logical architecture of the system is presented, as well as an example of the arrangement of devices in one of the entrance points to the zone, using the existing infrastructure for this purpose.
