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 possesses world-class search capabilities. Even for large-scale problems, it can efficiently find solutions within a limited computation time. • Data input is possible using a simple modeling language.

OptSeq is a general-purpose scheduling optimization solver specialized in scheduling optimization. It can describe various practical constraints and uses algorithms tailored for scheduling optimization problems, enabling it to provide good solutions in a short time for large-scale scheduling optimization problems that cannot be solved by mathematical optimization solvers. OptSeq considers renewable resources such as machines and people, non-renewable resources that are consumed such as money and materials, setup times, interruptions during work, resource occupancy and non-occupancy during interruptions, parallel tasks, selection of work modes, and arbitrary time constraints between tasks, allowing it to solve scheduling problems that minimize delays and mixed scheduling of forward and backward scheduling. Features: It allows modeling of scheduling optimization problems in a more natural expression (easier for humans to understand) compared to mathematical optimization solvers. Based on metaheuristics, it possesses world-class search capabilities. Even for large-scale problems, it can be solved extremely efficiently within limited computation time. It provides data input through a simple modeling language and a Python language interface.

SCOP (Solver for Constraint Programming) is a solver designed to quickly solve large-scale combinatorial optimization problems. By utilizing solution principles specialized for combinatorial optimization problems, SCOP can efficiently explore good solutions even for large problems that traditional mathematical optimization solvers cannot handle. Features: By defining variables in a different way than mathematical optimization solvers, it can significantly reduce the number of variables, enabling fast solutions. It allows for a more natural logical constraint description that is easier for humans to understand compared to mathematical optimization solvers. Based on metaheuristics, it possesses world-class search capabilities. Even for large-scale problems, it can solve them extremely efficiently within limited computation time. It provides data input through a simple modeling language and a Python language interface.

Demand forecasting, production optimization, inventory optimization, delivery optimization, logistics network optimization, personnel allocation optimization, revenue optimization, and more are possible. 'SCMOPT ZERO' is an integrated optimization system that can provide fast and good answers even for large-scale problems by designing models and selecting algorithms (solvers) based on the correct methodology of supply chain optimization. It can consider various constraints of real-world problems, requires minimal parameter settings, and does not need corrections due to unsatisfactory results. Taking into account the overall objectives and constraints, it automatically calculates balanced and appropriate answers from a vast number of combinations. Additionally, by adopting carefully selected solvers and models, it is capable of solving problems of the largest scale that can be addressed with existing technologies.
