A decision support system for substage-zoning filling design of rock-fill dams based on particle swarm optimization

Abstract

In this paper, we studied a substage-zoning filling design problem, which is considered as a complex problem with numerous tasks such as construction planning, dam access road and borrow placement, workspace filling, and construction project management. In analyzing workflows and the mechanism of substage-zoning filling, not only the above-mentioned tasks are considered, but also the environmental factors such as rainfall and hydrology characteristic temperature are taken into account. In this study, an optimization model for dam filling which aimed at reducing the disequilibrium degree of filling intensity was proposed; in addition, a technique based on particle swarm optimization was introduced as the basis of a decision support system for rock-fill dams. The system has been employed in a water conservancy and hydropower project which shows that the system is able to provide quality decision support and facilitate the rock-fill dam construction effectively.

Term frequency – function of document frequency: a new term weighting scheme for enterprise information retrieval

“…The emergence of interest in BI has increased in the recent decade (Li 1999, Feng et al 2001, Shi et al 2007, Duan et al 2007, Xu et al 2008, Jiang et al 2009, Wang et al 2011, Xu 2011a. However, many business analytics implementations have not yet employed the advanced technology.…”

Decision making viva genetic algorithm for the utilization of leftovers

“…For instance, a sub-stage-zoning filling is solved and a DSS is developed which is based on PSO. 46 A routing-based algorithm 47 is embedded in DSS which has combined heuristic 48 and GA approaches. In Reference [49], a Dijkstra algorithm 50 is given to produce a DSS for vehicle routing and scheduling problems.…”

Beton Ağırlıklı Barajların Simbiyotik Arama Algoritması ile Optimizasyonu

“…Kemer barajlarının optimum tasarımında da pek çok araştırma yapılmıştır [11][12][13][14]. Optimizasyon yöntemleri ile baraj tipleri [15] ve şekil farklılıklarının [16] maliyet üzerine etkileri de araştırılmıştır. Ayrıca optimizasyon algoritmaları arasındaki farkların barajlar üzerinden yapıldığı çalışmalarda mevcuttur [17].…”
