Solve detailed scheduling problems using CPLEX CP Optimizer

IBM ILOG CPLEX CP Optimizer is a necessary and important complement to the optimization specialists' toolbox for solving real-world operational planning and scheduling problems. IBM ILOG CPLEX CP Optimizer contains a robust optimizer that handles the side constraints that are invariably found in all real-world problems. For pure academic problems (e.g., job-shop, open-shop and flow-shop), it finds solutions that are comparable to solutions found by state-of-the-art, specialized algorithms.

Certain combinatorial optimization problems cannot be easily linearized and solved with traditional mathematical programming methods. To handle these problems, IBM ILOG CPLEX CP Optimizer provides a large set of arithmetic and logical constraints, as well as a robust optimizer that brings all the benefits of a model-and-run development process to combinatorial optimization.

Features

Detailed scheduling problems

  • Use modeling features specialized to scheduling like intervals (for activities) and cumul functions (for resources)
  • Support business goals by optimizing earliness and tardiness costs, duration costs and non-execution costs
  • Model the work breakdown structure of the schedule and task dependencies as well as multiple production modes
  • Model finite capacity resources and reservoirs
  • Model setup times to compute schedules that define the best possible sizes for batches

Combinatorial optimization problems

  • Use specialized constraints such as all-different, pack, lexicographic, count, and distribute for business problems such as facility location, routing, and configuration
  • Model with logical constraints as well as a full range of arithmetic expressions, including modulo, integer division, minimum, maximum, or an expression which indexes an array of values by a decision variable
  • Model with discrete decision variables (boolean or integer)
