Evolution of a supply chain management game for the trading agent competition
TAC SCM is a supply chain management game for the Trading Agent Competition (TAC). The purpose of TAC is to spur high quality research into realistic trading agent problems. We discuss TAC and TAC SCM: game and competition design, scientific impact, and lessons learnt
Effects of a Trust Mechanism on Complex Adaptive Supply Networks: An Agent-Based Social Simulation Study
This paper models a supply network as a complex adaptive system (CAS), in which firms or agents interact with one another and adapt themselves. And it applies agent-based social simulation (ABSS), a research method of simulating social systems under the CAS paradigm, to observe emergent outcomes. The main purposes of this paper are to consider a social factor, trust, in modeling the agents\' behavioral decision-makings and, through the simulation studies, to examine the intermediate self-organizing processes and the resulting macro-level system behaviors. The simulations results reveal symmetrical trust levels between two trading agents, based on which the degree of trust relationship in each pair of trading agents as well as the resulting collaboration patterns in the entire supply network emerge. Also, it is shown that agents\' decision-making behavior based on the trust relationship can contribute to the reduction in the variability of inventory levels. This result can be explained by the fact that mutual trust relationship based on the past experiences of trading diminishes an agent\'s uncertainties about the trustworthiness of its trading partners and thereby tends to stabilize its inventory levels.Complex Adaptive System, Agent-Based Social Simulation, Supply Network, Trust
Mean-Field-Type Games in Engineering
A mean-field-type game is a game in which the instantaneous payoffs and/or
the state dynamics functions involve not only the state and the action profile
but also the joint distributions of state-action pairs. This article presents
some engineering applications of mean-field-type games including road traffic
networks, multi-level building evacuation, millimeter wave wireless
communications, distributed power networks, virus spread over networks, virtual
machine resource management in cloud networks, synchronization of oscillators,
energy-efficient buildings, online meeting and mobile crowdsensing.Comment: 84 pages, 24 figures, 183 references. to appear in AIMS 201
Steering supply chains from a complex systems perspective
Purpose – The purpose of this research is to systematically review the properties of supply chains
demonstrating that they are complex systems, and that the management of supply chains is best achieved by
steering rather than controlling these systems toward desired outcomes.
Design/methodology/approach – The research study was designed as both exploratory and explanatory.
Data were collected from secondary sources using a comprehensive literature review process. In parallel with
data collection, data were analyzed and synthesized.
Findings – The main finding is the introduction of an inductive framework for steering supply chains from a
complex systems perspective by explaining why supply chains have properties of complex systems and how to
deal with their complexity while steering them toward desired outcomes. Complexity properties are
summarized in four inter-dependent categories: Structural, Dynamic, Behavioral and Decision making, which
together enable the assessment of supply chains as complex systems. Furthermore, five mechanisms emerged
for dealing with the complexity of supply chains: classification, modeling, measurement, relational analysis
and handling.
Originality/value – Recognizing that supply chains are complex systems allows for a better grasp of the
effect of positive feedback on change and transformation, and also interactions leading to dynamic equilibria,
nonlinearity and the role of inter-organizational learning, as well as emerging capabilities, and existing tradeoffs
and paradoxical tensions in decision-making. It recognizes changing dynamics and the co-evolution of
supply chain phenomena in different scales and contextsinfo:eu-repo/semantics/publishedVersio

Fairness in online vehicle-cargo matching: An intuitionistic fuzzy set theory and tripartite evolutionary game approach
This paper explores the concept of fairness and equitable matching in an
on-line vehicle-cargo matching setting, addressing the varying degrees of
satisfaction experienced by shippers and carriers. Relevant indicators for
shippers and carriers in the on-line matching process are categorized as
attributes, expectations, and reliability, which are subsequent quantified to
form satisfaction indicators. Employing the intuitionistic fuzzy set theory, we
devise a transformed vehicle-cargo matching optimization model by combining the
fuzzy set's membership, non-membership, and uncertainty information. Through an
adaptive interactive algorithm, the matching scheme with fairness concerns is
solved using CPLEX. The effectiveness of the proposed matching mechanism in
securing high levels of satisfaction is established by comparison with three
benchmark methods. To further investigate the impact of considering fairness in
vehicle-cargo matching, a shipper-carrier-platform tripartite evolutionary game
framework is developed under the waiting response time cost (WRTC) sharing
mechanism. Simulation results show that with fairness concerns in vehicle-cargo
matching, all stakeholders are better off: The platform achieves positive
revenue growth, and shippers and carriers receive positive subsidy. This study
offers both theoretical insights and practical guidance for the long-term and
stable operation of the on-line freight stowage industry.Comment: 36 pages, 15 figure
