SimpleRose positions itself as an optimization company providing:
1) Optimization consulting and decision-support solution delivery for planning and scheduling use cases (supply chain, manufacturing, workforce, asset maintenance, portfolio, energy/resource planning).
2) "Rose", a parallel optimization solver designed for large-scale LP/MILP (linear programming / mixed-integer linear programming) workloads, with a focus on distributed solving and CPU+GPU parallelization.
On the product site, Rose is described as a solver that parallelizes not only LP relaxations but also components of branch-and-bound (branching, cuts, heuristics) across CPUs and GPUs. The vendor states that reduced solve times can enable larger models and reduce the need for simplifying assumptions, potentially improving decision outcomes.
