Phoenix APS vs Siemens Opcenter

Phoenix APS helps planners build feasible production schedules across machines, people, and tools while accounting for calendars, setups, dependencies, and material availability. It enforces capacity limits on machines, lines, and human skills, and models parallel, alternative, and sequential routings at operation level. Machines, operators, and equipment can be scheduled together. Calendar handling includes closures and working-time changes, while dependencies support finish-to-start relationships with configurable lags. Material checks use bill-of-material availability with Fixed or Proportional quantities and AtStart, Uniform, or AtEnd laws. Planners can change assignments and rules to see the impact; infeasible jobs can be parked with reasons and retried using targeted relaxations. The interface includes a Gantt timeline, operations table, quick filters, and a what-if solver. HTTP JSON endpoints let ERP or MES systems send master data and retrieve dated plans. The maker describes the approach as heuristic and rule-based, aimed at fast, explainable feasible plans, with optimization modules on the roadmap. A free beta evaluation installer is available for Windows, but its temporary license does not permit production use. The project is described as personal and non-commercial.
