Their complex nature due to the various stakeholders and the variety of different social services they have to deliver, call for a holistic approach in their design, which qualifies the soft systems methodology as the appropriate tool for designing such systems. To support this argument and pave the way for online integrated information systems in social administration, this paper shows how to apply the first four steps of SSM onto a general social administration context, and proposes a conceptual model of an information system in the area of childcare services as an example.

In this paper, a chassis automatic levelling control system is designed. Position error control method and angle error control method are used to control the chassis automatic levelling control system, which is divided into ground clearance height adjustment and chassis levelling control strategy, respectively. The system is controlled by combining fuzzy control algorithm and preset point levelling method. The experiment was carried out on the chassis of our self-developed multi-functional plant protection machine with high ground clearance. The results show that the automatic levelling system can complete the chassis levelling well. Its average horizontal error is < 0.20°, root mean square error < 0.25°, maximum error is 1.13°, average levelling time < 26 s, and levelling precision < 0.2°. The system can meet the operation requirements of plant protection machine. Journal: Int.

In the software development life cycle (SDLC), software development teams need to apply several systematic activities at interrelated stages to produce a project that meets customer expectations. However, developers usually encounter enormous challenges while developing new projects. To eliminate these challenges and to develop better and reliable software, a new design approach that is based on systematic software reuse and CBR technique is discussed in this paper. A software design system that adopts the reusability approach in software engineering and the CBR technique was applied to provide solutions in the form of software patterns based on functionalities and features of similar past projects. The produced system will attempt to eliminate the challenges regarding time, effort, and financial constraints by reducing the effort needed in software development activities regarding requirement elicitation, analysis, and specification.

Moreover, it is readily understood that this process is supported by the use of various stochastic discounting models. The present paper concentrates on the formulation and the representation as a random contraction of a stochastic discounting model. The paper also provides an interpretation of the formulated stochastic discounting model in proactive treatment of the severity of a global risk. Journal: Int. J. of Applied Systemic Studies Pages: 26-30 Issue: 1 Volume: 9 Year: 2020 Keywords: global risk; model; discounting; random contraction.

Abstract: The paper presents overview of selected methods and tools of crisis management and compare their steps with steps of systems methodologies from high-level perspective. It is aimed to the methods and tools that comprise systems methodologies - hard and soft. Author focused on analysis of selected tools that are used in disaster management. A comparison of the steps of crisis management methods and systems methodology was done. Based on this comparison, it is possible to point out that systems approach already exists in few of methods of crisis management. The main finding is that only one method of crisis management creates and develops model that helps to abstract the decision. The main benefit of the article is to spread knowledge of systems approach in crisis management. Journal: Int.

The parametric equations of measuring points are obtained by mathematical model. The model and boundary are measured by establishing reference orbit coordinate system based on laser tracking. By using self-calibration multi-sensor system calibration and DGPS/IMU integrated processing, the internal and external bits of each binocular image are calculated, and the relative relations of each element in the stereo image are constructed. Combining with the vehicle boundary, the vehicle boundary parameters are calculated to realise the static boundary detection of rail transit vehicles. Experimental results show that this method can effectively improve the accuracy of vehicle boundary detection and reduce the relative error of vehicle boundary detection. Journal: Int.

Therefore, an optimal control method of torsional vibration in mechanical transmission system based on variable structure PID fuzzy control is proposed. With this method, a constraint parametric model for torsional vibration in mechanical transmission system is constructed. The simulation experiment results show that the proposed method can control the torsional vibration in the mechanical transmission system steadily with relative strong adaptive tracking compensation ability of torsional moment and other parameters, which indicates that the method improves the robustness of mechanical transmission with good buffeting elimination and suppression performance during mechanical transmission.
