What is DELMIA Ortems? Modules, integrations and alternatives
DELMIA Ortems is advanced planning and scheduling software offered by Dassault Systemes under its DELMIA brand, and it is often still referred to simply as Ortems. It produces finite-capacity production schedules from ERP data. It is aimed at factories that need feasible plans across constrained resources.
Also known as: Ortems, DELMIA Ortems APS
DELMIA Ortems provides finite-capacity planning and scheduling for production environments. Like other APS products, it takes orders and routings from an ERP and arranges operations around machine, labor, tooling and material limits, highlighting conflicts and late orders.
It is part of the DELMIA portfolio within Dassault Systemes, which also includes DELMIA Apriso for manufacturing operations management and DELMIA Quintiq for planning in other contexts. Manufacturers already using the 3DEXPERIENCE platform or DELMIA products often evaluate it alongside those tools.
In a stack it connects ERP, scheduling and shop floor execution. It does not replace the ERP; it improves the realism of dates and sequences the ERP cannot compute on its own, and can feed an MES for dispatching.
Modules and capabilities
Finite-capacity scheduling
Builds detailed schedules against resource calendars and constraints.
Interactive planning board
Graphical view for reviewing, adjusting and publishing the schedule.
Constraint and rule configuration
Models setups, tooling, labor and material constraints.
What-if scenarios
Compares schedule options and the impact of disruptions.
Order and load analysis
Shows resource load, bottlenecks and late orders.
ERP and MES connectivity
Exchanges orders, schedules and status with surrounding systems.
Integrations and data access
ERP data exchange
Imports orders, routings, BOMs and inventory, and returns schedule results to the ERP.
DELMIA Apriso
Can be coordinated with DELMIA Apriso for execution, subject to vendor guidance.
3DEXPERIENCE platform
Manufacturing data can relate to product structures managed on the Dassault platform.
Database and file interfaces
Commonly integrated via staging tables or flat files where no packaged connector exists.
APIs
Programmatic interfaces support automation; verify current details in vendor documentation.
Strengths
- Finite-capacity scheduling with configurable constraints
- Fits organizations already standardized on DELMIA or Dassault Systemes
- Interactive planning board with scenario analysis
- Works alongside existing ERPs rather than replacing them
Limitations
- Implementation depends on accurate master data and careful modeling
- Naming across the DELMIA portfolio can make product research confusing
- Best value often tied to wider Dassault investment
- Adds integration and maintenance work to the stack
Where AI helps DELMIA Ortems users
- - Auditing routing and capacity data before scheduling runs
- - Explaining why specific orders are late in plain language
- - Comparing planned and actual cycle times and flagging master data drift
- - Drafting planner briefings that summarize schedule changes
- - Read-only conversational queries over load and order status
Evaluating DELMIA Ortems? Check these
- Clarify how Ortems differs from other DELMIA planning products for your use case
- Test with your real routings and setup rules in a pilot
- Confirm how schedules return to the ERP and how re-planning is triggered
- Ask about integration with DELMIA Apriso if you plan to run both
- Budget for data cleanup and modeling effort
- Compare with ERP-native finite scheduling for simpler operations

Frequently asked questions
What is DELMIA Ortems?
DELMIA Ortems is advanced planning and scheduling software from Dassault Systemes. It uses ERP orders, routings and resource constraints to build finite-capacity production schedules, with a graphical board for adjustment and scenario comparison.
Is Ortems the same as DELMIA Ortems?
Ortems is the original product name, and it became part of the DELMIA brand at Dassault Systemes. Practitioners often still say Ortems, so searches and documentation use both terms for the same family of scheduling software.
Does DELMIA Ortems replace the ERP?
No. It sits beside the ERP, which remains the system of record for orders, inventory and finance. Ortems provides more realistic, constraint-aware dates and sequences than most ERP schedulers calculate.
What are alternatives to DELMIA Ortems?
Common alternatives are PlanetTogether, Siemens Opcenter APS and Asprova for production scheduling, and Kinaxis Maestro for supply chain planning. Your ERP's own scheduling option may also be adequate in low-complexity plants.
Where does AI help with Ortems?
AI helps around the scheduler by validating data, explaining late orders, summarizing changes and answering planner questions over read-only data. The scheduling engine produces the plan, and write-backs to ERP should stay behind human approval.
