An improved multivariate loss function approach to optimization
Journal of Systems Science and Systems Engineering - Tập 13 - Trang 318-325 - 2004
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...
Consumer-Driven Group Buying: Trick or Treat to Retail Stores?
Journal of Systems Science and Systems Engineering - Tập 27 - Trang 1-23 - 2017
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.

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
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...
Toward collective intelligence of online communities: A primitive conceptual model
Journal of Systems Science and Systems Engineering - - 2009
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...
Optimal pricing of a personalized product
Journal of Systems Science and Systems Engineering - Tập 17 - Trang 30-35 - 2007
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
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...
An extended aggregated ratio analysis in DEA
Journal of Systems Science and Systems Engineering - Tập 20 - Trang 249-256 - 2011
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...
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
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...

Healthcare: A complex service system
Journal of Systems Science and Systems Engineering - - 2009
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...
