An improved multivariate loss function approach to optimization
Journal of Systems Science and Systems Engineering - Tập 13 - Trang 318-325 - 2004
Yizhong Ma, Fengyu Zhao
The basic purpose of a quality loss function is to evaluate a loss to customers in a quantitative manner. Although there are several multivariate loss functions that have been proposed and studied in the literature, it has room for improvement. A good multivariate loss function should represent an appropriate compromise in terms of both process economics and the correlation structure among various...... hiện toàn bộ
Consumer-Driven Group Buying: Trick or Treat to Retail Stores?
Journal of Systems Science and Systems Engineering - Tập 27 - Trang 1-23 - 2017
Qijun Qiu, Li Jiang
Group buying (GB) has emerged and evolved into various forms over the past decade. We investigate a distinct form of GB, namely consumer-driven group buying, whereby some consumers form purchase groups to visit stores together and negotiate for discounts. We refer to these consumers as GB consumers that differ from regular consumers who visit stores individually and pay regular prices. Visited by ...... hiện toàn bộ
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
Optimal pricing of a personalized product
Journal of Systems Science and Systems Engineering - Tập 17 - Trang 30-35 - 2007
Suresh P. Sethi
This paper deals with optimal pricing of a personalized product such as a personal portrait or photo. A new model of the pricing structure inspired by two real-life cases is introduced to the literature and solved to obtain optimal photo sitting fees and the final product price. A sensitivity analysis with respect to the problem parameters is performed.
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
GreenCommute: An Influence-Aware Persuasive Recommendation Approach for Public-Friendly Commute Options
Journal of Systems Science and Systems Engineering - Tập 27 - Trang 250-264 - 2018
Shiqing Wu, Quan Bai, Sotsay Sengvong
Negative impacts produced by transportation sector have increased in parallel with the increase of urban mobility. In this paper, we introduce GreenCommute, a novel recommendation system which can facilitate commuters to take public friendly commute options, while provide support to alleviate the external cost in society, such as traffic pollution, congestion and accidents. In the meanwhile, a rew...... hiện toàn bộ
A survey of stackelberg differential game models in supply and marketing channels
Journal of Systems Science and Systems Engineering - - 2008
Xiuli He, Ashutosh Prasad, Suresh P. Sethi, Genaro J. Gutiérrez
Healthcare: A complex service system
Journal of Systems Science and Systems Engineering - - 2009
James M. Tien, Pascal J. Goldschmidt-Clermont
Healthcare is indeed a complex service system, one requiring the technobiology approach of systems engineering to underpin its development as an integrated and adaptive system. In general, healthcare services are carried out with knowledge-intensive agents or components which work together as providers and consumers to create or co-produce value. Indeed, the engineering design of a healthcare syst...... hiện toàn bộ
