In this paper, an agent-based structure of the electricity retail market is presented based on which day-ahead (DA) energy procurement for customers is modeled. Here, we focus on operation of only one Retail Energy Provider (REP) agent who purchases energy from DA pool-based wholesale market and offers DA real time tariffs to a group of its customers. As a model of customer response to the offe...

This paper focuses on the robust mixed H2/H∞ observer design problem for removal of NOx sensor ammonia cross-sensitivity in selective catalytic reduction (SCR) systems. Due to the ammonia cross-sensitivity, the reading of the NOx sensor is contaminated severely. In order to utilize the concentration of the NOx in the downstream tailpipe, it is desired to design an observer to estimate the actua...

Planning and scheduling research is becoming an increasingly interesting topic in the Arti...cial Intelligence area, because of its immediate application to real problems. Although the last few years have seen dramatic advances in planning systems, they have not seen the same advances in the methods of solving planning and scheduling problems. In this paper, an intuitive way of integrating inde...

Scheduling support is very important for calendar management in order to automatize the execution of possibly complex reasoning tasks. However, an interactive approach is desirable to enable the user to steer the allocation of events, which is a rather personal and critical kind of activity. This paper proposes a mixed-initiative scheduling model supporting the user’s awareness during the explo...

In the context of Scheduling under uncertainty, Partial Order Schedules (POS) provide a convenient way to build flexible solutions. A POS is obtained from a Project Graph by adding precedence constraints so that no resource conflict can arise, for any possible assignment of the activity durations. In this paper, we use a simulation approach to evaluate the expected makespan of a number of POSs,...

Routing protocols in DTNs usually utilize multiple message copies to guarantee the message delivery, in order to overcome unpredictable node mobility and easily-interrupted connections. A store-carry-and-forward paradigm was also proposed to further improve the message delivery. However, excessive message copies lead to the shortage of buffer and bandwidth. The spray and Wait routing protocol h...

The emergence of the circular economy concept has pushed industry owners towards green supply chain and waste reduction. closed-loop originates from its purpose is to increase efficiency profitability by reducing energy consumption. Hence, in this research, an integrated bi-objective mixed-integer linear programming model developed with aim optimizing both operational strategic decisions a netw...
