Problem Instances for Multi-crane Scheduling in Container Yard Terminal
Description
Problem Instances for Multi-crane Scheduling in Container Yard Terminal Data Abstract: The problem environment for instances involves three cranes within two blocks. The number of tasks (excluding dummy tasks for the initial position and availability) ranges from 6 to 12. Each instance (.csv) comprises the following: - K: Number of cranes - Z: Number of blocks - B: Number of bays within a block - BL: The far-left bay of blocks - BR: The far-right bay of blocks - CBL: The crane operating range left - CBR: The crane operating range right - M: The bigM penalty - unit: The constant processing time of a single container operation (or movement) by a yard crane - clearance: The minimum safety distance between two adjacent YCs - N: Number of tasks, excluding dummy tasks - T: Number of time steps in the planning time horizon - release: The release time of task i - bay: The bay location of task i - row: The row location of task i - tier: The initial layer location of task i. If i is on the top of the stack, then 1 - initCraneBay: The bay location of dummy tasks (initial crane position) - initCraneTime: The release time of dummy tasks (initial crane availability) - OFV (Optimality Gap): The objective function value of the optimal solution or the best-found solution with the optimality gap.
