Abs t rac t . We outline the formal modelling of a software system to support the scheduling and rescheduling of trains. The current (prototype) system supports only centralized rescheduling, but in practice rescheduling is done on an area basis, and a distributed system is required. Developing a distributed system involves the notions of delegability of functions to adjust schedules and distri...

We present here a discipline for job shop rescheduling based on partial order backtracking. We show that partial order backtracking ooers the rescheduler a framework for schedule repair, based upon a set of nogoods, which impose a systematic partial order on the set of activities to be repaired but allows non systematic techniques to be used within that framework. We present rescheduling as par...

This paper describes the design, implementation, visualizations, results and lessons learned of a novel real-world socio-technical research system for the purpose of rescheduling train drivers in the event of disruptions. The research system is structured according to the Actor-Agent paradigm: here agents assist in rescheduling tasks of train drivers. Coordination between agents is based on a t...

Delayed processing time and machine failures upset the plan in steelmaking-continuous casting (SCC) production, which make production plan infeasible. The manual repairing cannot satisfy objectives of quick response and optimal scheduling. The practical rescheduling with 1-4 refining stages cannot abstract as three stages hybrid flow shop (HFS). A method is presented for the rescheduling proble...

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...

Abstract Carrier-based aircraft maintenance tasks are conducted in time-critical, resource-constrained, and uncertain environments. Optimizing the scheduling allocation scheme of personnel equipment, reasonably responding to uncertainty disturbances, maintaining a high fleet availability vital combat training missions carrier-based aircraft. The task problem for is investigated this study. Firs...

This paper aims at the rescheduling of observing spacecraft imaging plan under uncertainty using ant colony algorithm. First, this paper provides a brief analysis about the uncertainties in spacecraft observation scheduling. And then, this paper establishes the mathematical model and manages to solve the rescheduling problem by ant colony algorithm. Finally, the above method is applied to solve...

We present a model for task rescheduling in multi-agent manufacturing that is geared toward maximising system efficiency and reliability in an environment with predictable failure patterns. We describe a distributed manufacturing system architecture [1] to illustrate the merits of rescheduling. We also develop an action redistribution framework based upon resource cooling, ie migrating actions ...
