With growing of the great interest in the energy problems, real-time pricing (RTP) for power systems has attracted attentions in the world. In our research, the new distributed optimization method is proposed for RTP. It is based on information exchanges between players (consumers, suppliers and distributors) through networks. In the past our research, the time required for information exchange is not considered. However, in actual systems, the time required for the wireless communication causes the time delay and instabilities of the system. Then this paper proposed to compensate for time-delay by prediction of demand-supply quantities.

We examine a feasibility study on multi-agent simulation for Hotelling model and then propose the prototype. Hotelling model is a theory that explains the consequence of the location competition of two sellers by analytically solving optimization problems in game situations. This model is employed to explain little product differentiation and agglomeration of retail shops. By introducing agent-based modeling and simulation, we could model complex situations which analytical approach can't explain. In particular, it will be widely applicable a relationship between change of consumer preference due to time change and seller's repositioning, and shopping vulnerable as an interaction of consumers and retailers.

<p>This research aims to develop a web application to realize open model-based collaboration (Open MBC), which is a framework to support efficient and collaborative development of complex systems. We describe the concept of Open MBC and the features of the web application. Furthermore, we introduce an actual case, presenting requirements analysis and management to use the application in the CubeSat project at Osaka Prefecture University. Feedback from students described the difficulty of systems engineering and functional weaknesses prevented the use of our application. Based on this feedback, the paper proposes improvements to functions and operation methods. </p>
