Merging optimality conditions with genetic algorithm operators to solve single machine total weighted tardiness problemJournal of Systems Science and Systems Engineering - Tập 14 - Trang 187-206 - 2005
Ibrahim M. Al-Harkan
In this paper, a constrained genetic algorithm (CGA) is proposed to solve the single machine total weighted tardiness problem. The proposed CGA incorporates dominance rules for the problem under consideration into the GA operators. This incorporation should enable the proposed CGA to obtain close to optimal solutions with much less deviation and much less computational effort than the conventional...... hiện toàn bộ
Toward collective intelligence of online communities: A primitive conceptual modelJournal of Systems Science and Systems Engineering - - 2009
Shuangling Luo, Haoxiang Xia, Taketoshi Yoshida, Zhongtuo Wang
Inspired by the ideas of Swarm Intelligence and the “global brain”, a concept of “community intelligence” is suggested in the present paper, reflecting that some “intelligent” features may emerge in a Web-mediated online community from interactions and knowledge-transmissions between the community members. This possible research field of community intelligence is then examined under the background...... hiện toàn bộ
An extended aggregated ratio analysis in DEAJournal of Systems Science and Systems Engineering - Tập 20 - Trang 249-256 - 2011
Malin Song, Jie Wu, Yumei Wang
Data Envelopment Analysis (DEA) and Ratio Analysis (RA) are two widely used methods for measuring units’ productivity and any other criteria that could be assessed based on the available input and output variables. A number of researchers have studied DEA and RA and noted the positive and negative differences between them. Aggregated ratio analysis (ARA) model, which provide an important linkage b...... hiện toàn bộ
A price-setting newsvendor model under CVaR decision criterion with emergency procurementJournal of Systems Science and Systems Engineering - Tập 19 - Trang 85-104 - 2010
Minghui Xu
In this paper, we consider a newsvendor model in which a risk-averse manager faces a stochastic price-dependent demand in either an additive or a multiplicative form. An emergency purchase option is allowed after the realization of demand to satisfy the units that are short. By adopting conditional value-at-risk (CVaR) as the decision criterion, we aim to investigate the optimal pricing and orderi...... hiện toàn bộ
Comparing two clustering-based techniques to track mobile nodes in industrial wireless sensor networksJournal of Systems Science and Systems Engineering - Tập 25 - Trang 177-209 - 2016
Mohammad Gholami, Robert W. Brennan
Tracking mobile nodes in dynamic and noisy conditions of industrial environments has provided a paradigm for many issues inherent in the area of distributed control systems in general and wireless sensor networks in particular. Due to the dynamic nature of the industrial environments, a practical tracking system is required that is adaptable to the changes in the environment. More specifically, gi...... hiện toàn bộ
Three aspects on solving queuing service system in Shanghai world expoJournal of Systems Science and Systems Engineering - Tập 22 - Trang 340-361 - 2013
Jifa Gu, Shanying Xu, Yong Fang, Kan Shi, Benfu Lv, Geng Peng, Bo Wang, Li Song, Rong Xie
This paper analyzes the queuing problem that was experienced during the Shanghai World Expo of 2010. The queuing problem will be discussed at three levels. The three levels include the physical, psychological, and social aspects of the queuing problem. The collective behavior of visitors is studied through analyzing the information from the different sources, such as, the network of electronic eye...... hiện toàn bộ
