Deregulation and restructuring have become unavoidable trends to the power industry recently, in order to increase its efficiency, to reduce operation costs, or to provide customers a better service. The once centralized system planning and management must be remodeled to reflect the changes in the market environment. We propose and have developed a multi-agent based system to assist players, s...

In this paper, I review the evolution and characteristics of South Korea’s financial system since the early 1960s. The South Korean experiences are then used to argue that the distribution of the knowledge about valuable businesses varies with the stage of economic development. This has implications for the design of financial system. In the early development stage when low labor cost is the ma...

Resource management in clusters traditionally uses centralized approaches, which restricts the cluster scale. To expand this limit, we develop a multi-agent approach to sharing resources across clusters in a decentralized manner. We organize shared clustered into an overlay network and formulate resource sharing in such a network as a distributed sequential resource allocation problem (DSRAP). ...

Resource allocation in computing clusters is traditionally centralized, which limits the cluster scale. Effective resource allocation in a network of computing clusters may enable building larger computing infrastructures. We consider this problem as a novel application for multiagent learning (MAL). We propose a MAL algorithm and apply it for optimizing online resource allocation in cluster ne...

Allocation of construction risks between clients and their contractors has a significant impact on the total construction costs. This paper presents a system dynamics (SD)-based approach for quantitative risk allocation. Using the proposed SD based approach, all the factors affecting the risk allocation process are modeled. The contractor’s defensive strategies against the one-sided risk alloca...

In wireless communications, power allocation plays a paramount role in sustainable network lifetime prolongation with quality-of-service and network interference reduction. This paper investigates a distributed power allocation problem in wireless parallel amplify-and-forward (AF) relay transmissions. Particularly, the objective is set to minimize the total transmit power while guaranteeing the...

This paper focuses on secondary frequency controlof large-scale power systems. First a centralized and a consen-sus control based distributed control law are presented, thena multi-level control law, named Multi-Level Power-ImbalanceAllocation Control (MLPIAC), for the large-scale power systemspartitioned into more than one region. The centralized anddistributed control ...

In this paper, we discuss two major tradeoffs, spatial and temporal tradeoffs, that appear when applying marketbased computing to multimedia network applications. The former appears between computation and communication cost, depending on how agents are distributed over network. The latter appears between reactiveness and correctness of result, depending on how the network environment dynamical...
