Fuzzy Hierarchy

The integrative fuzzy set pair model, established by set pair analysis (SPA) and fuzzy hierarchy analysis, was introduced to pre-evaluation of security states in the construction stage. Two relevant sets, evaluation index and dangerous standard, were analyzed and calculated in terms of the identity, discrepancy and contradistinction[1]. The indices and weights were determined by Delphi and fuzzy hierarchy analysis respectively in order to establish the integrative fuzzy set pair model of construction stage. Finally, the model was applied to the case study of Shenyang sewage treatment plant and the results demonstrated that the method proposed in this present paper is satisfactory.

Centralized System

The era is now facing water scarcity and the available water is being depleted at a faster rate to meet the needs of the growing population. At this juncture, it is essential to use the reduce-reuse-recycle strategy. Reducing excessive usage of water for essential needs and reusing the recycled water for non-consumptive purposes can be a great step in the conservation of water. The waste water from various sources can be collected and treated using an STP. In most of the cases, water treatment requires a centralized system of control and operation. The STP should be designed by considering the inflow characteristics, objective of the water treatment and availability of resources. There are various operational and managerial constraints while designing an STP. In case of overloaded condition of available STP, either some modification has to be done to prevent the decrease in efficiency of the obtained output or a new plant has to be constructed. In this case study, we have analyzed three different approaches to solve the issue of an overloaded STP. The results based on various criteria including cost of construction and maintenance have been discussed.
