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...
Complete Modification Rescheduling Method and Its Application for Steelmaking and Continuous Casting
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...
Congestion management is one of the major tasks performed by system operators (SOs) to ensure the operation of transmission system within operating limits. To permit smooth and quality flow of power the problem of congestion has to be solved. The congestion in the transmission line will be removed by generation rescheduling with the cost involved in the rescheduling process should be minimized....
Real-time train dispatching (i.e., rescheduling and replatforming) in passenger railway stations is a very important challenging task. In most major stations, this task carried out by hand highly trained dispatchers who use their extensive experience to find near-optimal solutions under conditions. With several simultaneous deviations from the timetable, however, traffic situation may become to...
Scheduling plays a vital role in ensuring the effectiveness of the production control of a flexible manufacturing system (FMS). The scheduling problem in advance manufacturing system such as flexible manufacturing system (FMS) is considered as dynamic as new orders may arrive intermittently day-to-day. The newly arrived orders need to be desegregated with the existing production schedule immedi...
Operating rooms (ORs) in US hospitals are costly to staff, generate about 70 % of a hospital's revenues, and operate at a staffed-capacity utilization of 60-70 %. Many hospitals allocate blocks of OR time to individual or groups of surgeons as guaranteed allocation, who book surgeries one at a time in their blocks. The booking procedure frequently results in unused time between surgeries. Reali...
With the current trend towards cognitive manufacturing systems to deal with unforeseen events and disturbances that constantly demand real-time repair decisions, learning/reasoning skills and interactive capabilities are important functionalities for rescheduling a shop-floor on the fly taking into account several objectives and goal states. In this work, the automatic generation and update thr...
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 ...
