Simulation a Brief Introduction A computer simulation (or "sim") is an attempt to model

Simulation a Brief Introduction A computer simulation (or "sim") is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied to see how the system works. Service processes Games or Gamification (Driving or Flight Simulators, Popular Sim games series) Weather Scientific e. g. Chemical processes, Physics Simulation Areas Medical (surgery, mannequins) Economics Social Behaviour Networks Industrial & Manufacturing processes Simulations are used in many areas and there are different types of simulation 4

Simulation Introduction • We are focusing on using simulation for Process Improvement as an integrated part of a Business Transformation Approach. • Operational and Process simulations are useful in modelling the flow of transactions/entities through business processes/operation. • Many software tools support process modelling including some BPMN models. 5

Why Simulate Operations? Visualises operation Improve Performance & Productivity • It shows a ‘live’

Why Simulate Operations? Visualises operation Improve Performance & Productivity • It shows a ‘live’ and visual representation of the process • Analysing Cycle time • Identifying bottlenecks • Optimise resource utilisation Lower Cost Evaluation • Cheaper than real life by evaluating changes before investment Gain Insight to change effects • Experiment with new ideas before implementation • Make better decisions by comparing scenarios to consider all the possibilities • Understand where is the ‘tipping point’ Time Saver Safe • Run scenarios spanning months/years in seconds • Predict future performance by forecasting • Done in safety - It allows you simulate different scenarios risk free and quickly 6

Approach – Points to note for effective Simulation • Organisation to be modelled: • Requires a degree of organisational process maturity • A defined and stable process to model • Sufficient existing operational Data • People with skills in: • Process Modelling • Simulation tools • Statistical tools & Interpreting the data Optimising Managed Defined Repeatable Initial Use with Caution • Focus on process improvement • Processes are performance managed and controlled • Processes are documented and standards consistently applied • Processes are known and managed at unit levels • Processes unpredictable and uncontrolled • A Model is an abstraction of the real world complexities • Insufficient variability/Randomness • Different types of events/actions • Too many assumptions • Physical & Political impact of changes • Don’t Make it too Fragile, highly optimised without robustness or spare capacity. 10
