Fast solving of large-scale set cover optimization problems.
OptCover is a solver designed to quickly solve large-scale set cover optimization problems. The set cover optimization problem (not a strict definition) involves enumerating feasible solutions and finding the best combination among them. It can solve any problem where feasible solutions can be enumerated, including delivery optimization problems, scheduling problems, and other combinatorial optimization problems. Features: • Based on metaheuristics, it has world-class search capabilities. It can efficiently solve large-scale problems within a limited computation time. • Data input is possible using a simple modeling language.

Benchmark results: https://www.logopt.com/download/OptCover_benchmark.pdf The comparison results with commercial solvers such as CPLEX, Gurobi, and LocalSolver are also included. Within the same computation time, better solutions are obtained for most problem instances compared to these commercial solvers. Practical examples: It is possible to efficiently solve problems such as the proper allocation of rare resources like aircraft, trains, and buses in the aviation, railway, and bus industries. Due to the structure of these problems, general algorithms for personnel allocation or assignment problems cannot solve them efficiently. For example, in the aviation industry, based on customer demand forecasts, it is possible to efficiently create flight schedules between airports considering various constraints, allocate appropriate aircraft, and assign crew members. Additionally, for other combinatorial optimization problems such as delivery optimization and scheduling optimization, if the problem structure (which varies depending on the actual problem data) is better solved as a set covering problem, OptCover can provide good solutions in a shorter time.

Company information
Our company was established in 1991 to provide the highest level of technology for optimization in logistics (supply chain). Since then, we have expanded the scope of our optimization solutions beyond the supply chain and, starting around 2016, we have also been providing data analysis solutions using AI. We operate in Japan, China, and South Korea. With technical support from university professors who have extensive practical experience in the field of mathematical optimization both domestically and internationally, we develop products and provide services that enable us to solve difficult optimization problems that other companies cannot, thus offering world-class optimization solutions.
