Merging optimality conditions with genetic algorithm operators to solve single machine total weighted tardiness problem
Journal 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 model
Journal 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
The next industrial revolution: Integrated services and goods
Journal of Systems Science and Systems Engineering - Tập 21 - Trang 257-296 - 2012
James M. Tien
The outputs or products of an economy can be divided into services products and goods products (due to manufacturing, construction, agriculture and mining). To date, the services and goods products have, for the most part, been separately mass produced. However, in contrast to the first and second industrial revolutions which respectively focused on the development and the mass production of goods...... hiện toàn bộ
An extended aggregated ratio analysis in DEA
Journal 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 procurement
Journal 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
A one-stop logistic services framework supporting global supply chain collaboration
Journal of Systems Science and Systems Engineering - Tập 25 - Trang 229-253 - 2016
Amy J. C. Trappey, Charles V. Trappey, Sandy W. C. Chang, W. T. Lee, Tun Nien Hsu
A global enterprise must continuously improve the efficiency of logistic operations between supply chain collaborators. Integrating logistic services, resources, and necessary information flows in the supply chain to ensure efficiency and efficacy is critically important to these companies. Global logistic service companies face challenges from their clients to provide logistic services that are c...... hiện toàn bộ
Comparing two clustering-based techniques to track mobile nodes in industrial wireless sensor networks
Journal 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
Big Data: Unleashing information
Journal of Systems Science and Systems Engineering - Tập 22 - Trang 127-151 - 2013
James M. Tien
At present, it is projected that about 4 zettabytes (or 10**21 bytes) of digital data are being generated per year by everything from underground physics experiments to retail transactions to security cameras to global positioning systems. In the U. S., major research programs are being funded to deal with big data in all five sectors (i.e., services, manufacturing, construction, agriculture and m...... hiện toàn bộ
Theory and Implementation of Sensitivity Analyses Based on Their Algebraic Representation in the Graph Model
Journal of Systems Science and Systems Engineering - Tập 28 - Trang 580-601 - 2019
Jinshuai Zhao, Haiyan Xu, Keith W. Hipel, Baohua Yang
Sensitivity analyses based on an algebraic representation in the graph model for conflict resolution (GMCR) are generalized for ascertaining the robustness of stability results by varying decision makers’ preference ranking. The ordinal preferences in GMCR are advantageous to carry out sensitivity analyses with respect to systematically identifying the influence of preference alterations upon the ...... hiện toàn bộ
