Scheduling Maintenance Activities During Planned Outages At Nuclear Power Plants, Alan Mckendall, James Noble, Cerry Klein
Scheduling Maintenance Activities During Planned Outages At Nuclear Power Plants, Alan Mckendall, James Noble, Cerry Klein
Faculty & Staff Scholarship
In order to maintain high production rates, electric power as well as manufacturing plants shut down so that maintenance activities can be performed on machines/equipment. These planned shut downs (outages) usually occur at least once a year and are more frequent for plants with older machines/equipment. The major costs associated with outages are cost of materials, labor cost, and loss of production cost. Due to high cost incurred from loss of production, the objective is to schedule maintenance activities such that outage duration is minimized. Since the resources required to perform maintenance activities are very limited, the problem of scheduling …

A Simulated Annealing Heuristic For A Crane Sequencing Problem, Alan Mckendall, Jin Shang, James Noble, Cerry Klein
Faculty & Staff Scholarship
When maintenance activities during outages at electric power plants are scheduled using project management software, the locations of the resources required to perform the activities are determined such that the total distance the resources travel during the outage is minimized. This problem is defined as the dynamic space allocation problem (DSAP). Once the DSAP solution (i.e., assignment of activities and their required resources to workspaces and of idle resources to storage spaces) is obtained, the problem then is to determine the sequence in which the crane moves the resources to their required locations at the beginning of each period (i.e., …
