Gurobi Optimizer vs Lokad

Gurobi Optimizer converts mathematical models of business problems into optimal solutions. It handles linear, mixed integer, quadratic, combinatorial, nonlinear, conic, and multi-objective problems. For non-convex quadratic problems, its global optimization can prove a global optimum rather than only a local one. Solver capabilities include parallel and distributed optimization, presolve, cutting planes, heuristics, and symmetry handling. For model review, it provides sensitivity analysis, infeasibility analysis, feasibility relaxation, and solution quality attributes. APIs are available for C, C++, Java, .NET, Python, MATLAB, and R, enabling optimization models to be built into applications, services, and data pipelines. Deployment options include local, server, cloud, and container environments. Instant Cloud runs Gurobi on AWS or Azure without requiring users to deploy or maintain infrastructure. The included gurobipy license is for non-production use and limits models to 2,000 variables and 2,000 linear constraints, or 200 variables for models with quadratic terms. Free options also include a full-featured 30-day commercial evaluation license and an academic license for eligible institutions.

Lokad is a supply chain decision platform that uses predictive analytics and optimization to guide purchasing, allocation, pricing and prioritization. Its probabilistic forecasts represent possible future scenarios, and it links recommendations to financial impact and business objectives. Lokad automates routine calculations such as reorder quantities, multi-echelon allocations, lead-time adjustments and repair schedules. Users can build decision-generating applications in Envision, Lokad’s supply-chain-focused programming language. The recommended data exchange is file transfer by FTPS or SFTP, with options to push or pull files; native integrations with third-party apps are being phased out. Lokad serves industries including retail, aerospace, automotive, fashion, oil and gas, and manufacturing. The platform runs on the web, and a managed subscription typically includes end-to-end support from one or more Supply Chain Scientists. Pricing is on request. A free trial can be requested by email, and the reduced Envision Playground is available without registration. Lokad was founded in Paris in 2008.
