BPMN Simulation with BIMP 4 Levels Supported Level

BPMN Simulation with BIMP: 4 Levels Supported ● Level 1 - Process Validation ○ Evaluate the structure of the process diagram ● Level 2 - Time Analysis ○ Measure the end-to-end process time ● Level 3 - Resources Analysis ○ Predict how the process will perform with different levels of resources ○ Provide a reliable estimate of how the process will perform in operation ● Level 4 - Calendar Analysis ○ Include calendar information Τεχνολογία Διοίκησης Επιχειρησιακών Διαδικασιών, Γ. -Δ.

Level 1 - Process Validation ● Εισάγουμε: ○ Πλήθος tokens (ενάρξεις εκτέλεσης) στα start events ○ Πιθανότητα να ακολουθηθεί κάθε εναλλακτική επιλογή στα gateways ● Λαμβάνουμε: ○ ○ Number of completed instances. Number of token instances created. Number of instances that activate each shape. Number of finished instances. Τεχνολογία Διοίκησης Επιχειρησιακών Διαδικασιών, Γ. -Δ. Κάπος, 2018 -2019 3

Level 1 - Process Validation ● Μπορούμε να ελέγξουμε αν: ○ ○ ○ Gateways are synchronized. Messages are synchronized. Decisions probabilities are correctly assigned. Routing behaves as expected. All tokens have ended. Τεχνολογία Διοίκησης Επιχειρησιακών Διαδικασιών, Γ. -Δ. Κάπος, 2018 -2019 4

Level 2 - Time Analysis ● Λαμβάνουμε: ○ Instances completed: Indicates how many instances were processed. ○ Instances started: Indicates how many instances arrived at the shape. ○ Minimum time: Indicates the minimum processing time of the shape. ○ Maximum time: Indicates the maximum processing time of the shape. ○ Average time: Indicates the average processing time of the shape. ○ Total time: Indicates the total time employed to process the shape.
