Summary on Grant Application Form |

Within the academic field of operational research, one of the most active topics is scheduling. Scheduling involves the allocation of a given set of resources (for example, manpower, production machines and specialized equipment) to a given set of jobs over time. This proposal considers the relatively new topic of rescheduling. Rescheduling involves adjusting an already planned schedule to take into account disruptions of various types. The most common disruptions include: the arrival of new orders, order cancellations, changes in order priority, processing delays, changes in arrival times for incoming jobs, machine breakdowns, and the temporary unavailability of resources. Once an original schedule has been planned, resources will have been allocated to support that schedule. Moreover, reallocating those resources if the schedule is changed as a result of the disruption is typically expensive and time consuming. However, ignoring the disruption and using the originally planned schedule may be impossible, or may involve the loss of significant opportunities for profit. Therefore, some type of compromise schedule, which largely accommodates the effect of the disruption but does not incur excessive costs of disrupting the original schedule, needs to be found. This research provides mathematical approaches to finding such compromise schedules.
