The rescheduling strategy of semiconductor production refers to deciding when to start a rescheduling procedure and what kind of rescheduling method to be adopted. Both of the two problems are ill-structured and involve some fuzzy and random information. In order to solve this kind of production problem, a fuzzy Petri nets based rescheduling model (FPN-R) is proposed. FPN-R is defined as a 7-tu...

This paper proposes a novel approach for generation scheduling using sensitivitycharacteristic of a Security Analyzer Neural Network (SANN) for improving static securityof power system. In this paper, the potential overloading at the post contingency steadystateassociated with each line outage is proposed as a security index which is used forevaluation and enhancement of system static security....

Starting from the defined network topology and the timetable assigned beforehand, the paper considers a train rescheduling in respond to disturbances that have occurred. Assuming that the train trips are jobs, which require the elements of infrastructure – resources, it was done by the mapping of the initial problem into a special case of job shop scheduling problem. In order to solve the given...

This paper presents the review of past studies concerning mathematical models for rescheduling passenger railway services, as part of delay management in the occurrence of railway disruption. Many past mathematical models highlighted were aimed at minimizing the service delays experienced by passengers during service disruptions. Integer programming (IP) and mixed-integer programming (MIP) mode...

Abstract: This paper addresses the issues concerning the rescheduling of a static timetable in case of a disaster encountered in a large and complex railway network system. The proposed approach tries to modify the schedule so as to minimise the overall delay of trains. This is achieved by representing the rescheduling problem in the form of a Petri-Net and the highly uncertain disaster recover...

In realistic scenarios of disruption management the high number of potential options makes the provision of decision support – on how to get back on track – complex. It is thus desirable to reduce the size of the regarded problems by applying methods of partial rescheduling. As existing approaches (such as Affected Operations Rescheduling or Matchup Scheduling) mainly focus on production-specif...

This paper presents an optimal power flow method based on the generation rescheduling priority to enhance transient stability in power systems. In order to determine the generation rescheduling priority the energy margin sensitivity indices are calculated. The candidate generators for generation rescheduling are determined by the energy margin sensitivity indices and then optimal power flow (OP...
