Reliability with DPSIM

Reliability with DPSIM is an advanced DPSIM Full workflow for evaluating how failures, repairs, buffers, operating states and maintenance assumptions affect mineral processing plant performance over time.

DPSIM Static Module does not include reliability simulation, dynamic simulation or process control workflows. The Static Module is focused on steady-state flowsheet simulation, model reference review and engineering reporting.

What DPSIM Full Can Evaluate

• Equipment availability using MTBF, MTTR and project-specific failure and repair assumptions.
• Plant production impact from failures, repairs, standby equipment and partial-capacity operation.
• Buffer and stockpile behavior, including whether inventory can bridge upstream or downstream outages.
• Operating states such as running, stopped, failed, under repair, waiting, idle or constrained by another section.
• Scenario comparisons for maintenance strategy, redundancy, critical equipment and bottleneck mitigation.

From Component Availability to Production Impact

A simple availability calculation can identify weak components, but a mineral processing study often needs to answer a more practical question: how much production is lost, when does it happen, and which operating rule or design change improves the outcome?

DPSIM Full can connect reliability assumptions to flowsheet behavior so that failures and repairs are evaluated in the context of process capacity, inventory, recirculating loads and downstream constraints.

Typical Workflow

1. Build or review the process flowsheet and identify the equipment boundaries relevant to the study.
2. Define reliability and repair assumptions, including MTBF, MTTR, standby logic and maintenance constraints where applicable.
3. Represent buffers, stockpiles, equipment states and operating rules that influence production continuity.
4. Run time-based scenarios and compare availability, utilization, lost production and bottleneck behavior.
5. Review results with the project team and refine assumptions using plant data, vendor data or maintenance history.

DPSIM Static Module and DPSIM Full

DPSIM Static Module is the free public release for steady-state simulation and engineering reporting. It is useful for flowsheet setup, model review, mass balance work and communication of steady operating cases.

DPSIM Full is used for advanced project applications such as dynamic simulation, process control studies and reliability analysis. Contact EPM if your study requires these capabilities.
