Urban flood control system is a collection of various preventive measures taken to resist and mitigate flood. Assessment of urban flood control system safety is one of the important measures to coordinate the urban social planning and the urban flood control facilities.The assessment can also promote the sustainable development of city.In allusion to urban flood control system safety is a fuzzy concept with vague denotation, a fuzzy variable assessment model of urban flood control system safety is constructed in this paper based on theories of variable fuzzy sets and relative different functions.The method can determine relative membership degrees and functions of various indexes associated with the urban flood control system safety scientifically and reasonably; through changing the model,the stability of grade eigenvalues is tested; the mean of grade eigenvalues is calculated to improve the reliability of assessment results. The synthetical assessment of flood control system safety can be implemented with the method adopted in this paper.By 4 safety grades, 9 key indexes were screened in the urban flood control system of Jinan to implement the safety assessment in this paper. The case study of Jinan shows that the proposed method is of practical use.

AbstractIn recent years, it has become popular for some of countries and regions to adapt the system of governance to varied and complex issues concerned with regional development and the environment. Watershed management is possibly the best example of this. It involves flood control, water use management and river environment simultaneously. Therefore, comprehensive watershed-based management should be aimed at balancing those aims. The objectives of this study are to introduce the notion of environmental governance into the planning process, to establish a method for assessing the alternatives and to develop a procedure for determining the most appropriate plan for environmental governance. The planning process here is based on strategic environment assessment (SEA). To verify the hypothetical approach, the middle river basin in the Tokachi River, Japan was selected as a case study. In practice, after workshop discussions, it was found to have the appropriate degree of consensus based on the balance of flood control and environmental protection in the watershed.

Urban traffic can be curbed in various ways, for instance, by introducing paid unguarded parking zones (PUPZ). The operational functionality of this system depends on whether or not the various system features used to document parking cases function properly, including those which enable positioning of vehicles parked in the PUPZ, recognition of plate numbers, event time recording, and the correct anonymisation of persons and other vehicles. The most fundamental problem of this system is its reliability, understood as the conformity of control results with the actual state of matters. This characteristic can be studied empirically, and this article addresses the methodology proposed for such an examination, discussed against a case study. The authors have analysed the statistical dependence of the e-control system’s measurement errors based on operational data. The results of this analysis confirm the rationale behind the deployment of the e-control system under the implementation of the smart city concept in Warsaw.

Abstract By exemplifying the feeder service for the port of Kotka, this study proposed a multi-objective optimization model for feeder network design. Innovative for difference from the single-objective evaluation system, the objective of feeder network design was proposed to include single allocation cost, intra-Europe cargo revenue, equipment balance, sailing cycle, allocation utilization, service route competitiveness, and stability. A three-stage control system was presented, and numerical experiment based on container liner’s real life data was conducted to verify the mathematical model and the control system. The numerical experiment revealed that the three-stage control system is effective and practical, and the research ideas had been applicable with satisfactory effect.
