# Process Simulation

Process simulation allows you to simulate the execution of business processes to find out about cycle times, costs and resources. It can also be used to test the impact of changes between different variants of processes and then select the best variant for implementation. Process simulation thus helps you to determine and quantitatively evaluate the need for improvement. This makes simulation an important tool in process analysis and optimisation.

**For which model types is process simulation enabled?**

Process simulation is enabled for *Business Process Diagrams*.

**Where can I configure the data the simulation is based on?**

Unless otherwise stated, all attributes that need to be considered can be found in the Notebook chapter "Simulation data".

**What Information do I need to get started?**

To simulate a business process with meaningful results, you have to define at least the following simulation data:

The

*Execution time*of all included*Tasks*.The probability of alternative paths starting from an

*Exclusive gateway*. It can be defined in the*Transition condition*attributes of the outgoing*Sequence flows*.WskazówkaIn its simplest form, transition conditions are represented by floating point numbers

`≥`

0 and`≤`

1 (e.g. 0.7). The sum of the probabilities of all alternative paths starting from a gateway has to be 1.

**How can I perform a cost analysis with personnel costs?**

To perform a cost analysis with personnel costs, you have to determine the responsible roles and reference them in a business process:

For each

*Task*, assign the responsible*Roles*in the*Responsible for execution*attribute (Notebook chapter "RACI").At the

*Roles*, enter the*Hourly wages*of the employees.Enter the estimated non-personnel

*Costs*of performing the*Tasks*.

**How can process simulation help with capacity planning?**

For capacity planning, you need to determine how often a process occurs:

- At the
*Start event*, specify the*Quantity*(= number of occurrences) of this business process within the chosen*Time period*.

The attributes listed above are just a minimal set. In the following
section, the *attribute requirements* for process simulation are
examined more closely.

Process simulation is only available in the ADONIS Enterprise Edition. The availability of this feature also depends on the licence and the application library. All examples and descriptions in this chapter refer exclusively to the ADONIS BPMS Application Library.

If you are looking for a more lightweight solution than the process simulation, the process stepper provides a quick overview of specific process paths.

## Prepare Model for Simulation

Before you can simulate the execution of a business process, certain requirements need to be fulfilled. These requirements fall into two categories:

Requirements for the

*model structure*Requirements for the

*attributes*

Read on to learn more about these requirements.

### Start Events

The *Start Event* indicates where a particular process will start.

**Model Structure Requirements**

- Every
*Business Process Diagram*must contain exactly one*Start Event*object, which symbolizes the beginning of the process.

**Attribute Requirements**

- To show how often a process takes place, you need to fill in the
attributes
*Quantity*and*Time period*. If the*Quantity*attribute is empty, simulation will run with the default value "100". The default value for*Time period*is "Per Year".

You want to specify that a process takes place 100 times every day. Set
*Quantity* to "100" and *Time period* to "Per day".

### Tasks

A *Task* is an activity within a process flow. *Tasks* can have assigned
costs and times. If they are performed by people, it is also possible to
take work costs into account (see Role to learn more).

**Model Structure Requirements**

*Tasks*should be part of a process flow.

**Attribute Requirements**

To specify how long it takes to perform a

*Task*, use the*Execution time*attribute.*Waiting time*allows you to show time before work begins, while*Resting time*and*Transport time*show delays after a*Task*was executed.To state that carrying out a

*Task*generates costs, use the*Costs*attribute.You can also assign one or more

*Roles*to a Task in the*Responsible for execution*attribute (Notebook chapter "Organisation"). If you select two or more*Roles*, it is assumed all of them are needed for carrying out the*Task*.

You want to specify that a *Task* can be carried out in 10 minutes.
There are no waiting, resting or transport times, and no costs are
incurred. Set *Execution time* to "10 minutes".

### Subprocesses

A *Subprocess* is an activity that encapsulates a process. It allows you
to show that certain parts of a process are described in detail in the
linked sub model.

Simulation does not support inline *Subprocesses* (including "Ad-Hoc").

**Model Structure Requirements**

- To reference a
*Business Process Diagram*from a*Subprocess*, use the*Referenced subprocess*attribute (Notebook chapter "General information"). The linked sub model will also be simulated. If there is no linked sub model, simulation data can be defined directly at the*Subprocess*.

**Attribute Requirements**

Ideally, all attributes are calculated based on the analysis of the sub model, so you do not need to adapt any attributes apart from the

*Referenced subprocess*attribute.If there is no linked sub model, or if the relevant information should be taken directly from the

*Subprocess*, select the*Use aggregated subprocess values*check box. In this case, the relevant simulation data has to be defined directly at the*Subprocess*(see Tasks to learn more about the required attributes).

### Exclusive Gateways and Sequence Flows

An *Exclusive Gateway* is used to create alternative paths within a
process flow where only one of the paths can be taken.

**Model Structure Requirements**

- Model splitting paths using
*Exclusive Gateways*, not*Conditional Sequence Flows*.

**Attribute Requirements**

To define the probability of alternative paths starting from an

*Exclusive gateway*, adapt the*Transition condition*attributes of the outgoing*Sequence flows*.In its simplest form, transition conditions are represented by floating point numbers

`≥`

0 and`≤`

1 (e.g. 0.7).

The sum of probabilities for outgoing paths has to be 1. If no probabilities are defined, the simulation is performed under the assumption that all alternative paths occur with the same frequency (e.g. 50/50 for 2 outgoing paths). If transition conditions are defined for some, but not all outgoing paths, the simulation mechanism will calculate the remaining probability (what is missing to reach 100%) and distribute it evenly across all paths without a defined probability.

You want to specify that the path "private customer" is selected in 80%
of the cases, and the path "corporate customer" selected in 20% of the
cases. Set *Transition condition* to "0.8" for the first *Sequence flow*
and to "0.2" for the second *Sequence flow*.

**Advanced Methods of Defining Transition Conditions**

The method described above of representing transition conditions by floating point numbers can be considered as a discrete distribution.

When a process contains loops, you can use floating point numbers to assign different probabilities for consecutive executions of the loops. You can find out more about this in the section Limit Number of Loops.

In addition to floating point numbers, you can also use variables in discrete distributions. These can be used at different points in the process to define transition conditions. You can find out more about this in the section Decide Process Path Based on Dependent Probabilities.

In addition to the discrete distribution ADONIS also supports different types of continuous distributions: These are the normal distribution, the exponential distribution and the uniform distribution. To learn more about these probability distributions that can be used to specify the probability of alternative paths during process simulation, see Probability Distributions.

### Non-Exclusive Gateways

*Non-exclusive Gateways* allow you to show that multiple paths are
executed simultaneously.

**Model Structure Requirements**

- Fork and join parallel paths using
*Non-exclusive Gateways*which are defined as*Parallel*gateways (attribute*Gateway type*in the Notebook chapter "General information").

The simulation mechanism only supports *Parallel Gateways* for the
simulation of simultaneously running tasks. *Inclusive Gateways*
are
treated like *Exclusive Gateways* by the simulation.

### Intermediate Events

*Intermediate Events* are events that take place during a process.

In BPMN 2.0, there are two basic categories of *Intermediate Events*:
those belonging to a process flow and those attached to the boundaries
of activities.

*Intermediate Events (sequence flow)*are not evaluated by the simulation. To document delay in your process caused e.g. by waiting for a message from an external pool, use the*Waiting time*attribute in the subsequent*Task*.*Intermediate events (boundary)*allow you to show that certain events can take place during execution of a*Task*. They can be*interrupting*or*non-interrupting*(attribute*Type*in the Notebook chapter "Event type") You can define:How probable it is that the event occurs while the

*Task*is being executed (attribute*Probability of occurrence*).If the

*Task*is interrupted, what percentage of the*Task*is complete, that is, what fraction of costs and times should be added to the simulation results (attribute*Rate of activity completion at event occurrence*).

**Model Structure Requirements**

*Intermediate events (boundary)*need to be attached to a*Task*(attribute*Attached to*in the Notebook chapter "General information").

**Attribute Requirements**

- Adapt the
*Probability of occurrence*and*Rate of activity completion at event occurrence*attributes. Both parameters are defined by floating point numbers`≥`

0 and`≤`

1 (e.g. 0.7). The default values for both attributes are set to "0.5".

### End Events

*End Events* indicate where a process path will end.

**Model Structure Requirements**

- Model an
*End Event*for each path to allow a more in-depth analysis of the process results after a simulation run.

### Roles

*Roles* define responsibility for *Tasks*. They are used for calculating
personnel costs and capacities.

**Attribute Requirements**

- Adapt the
*Hourly wages*attribute to allow calculating the personnel costs of your process.

You want to specify that the employee who performs the role "Corporate
Account Manager" is paid 50 EUR (currency is implicit) per hour. Set
*Hourly wages* to "50".

## Run Simulation

In order to simulate one specific model:

Open the model in the graphical editor.

Click the

*More*button in the menu bar of the open model, point to*Process analysis*, and then click*Simulation*.Define the

*simulation parameters*:In the

*Number of calculation cycles*box, type the number of times you want ADONIS to simulate the model.In the

*Working days per year*box, type the number of working days per year.In the

*Working hours per day*box, type the number of working hours per day.

WskazówkaThe higher the number in the

*Number of calculation cycles*box, the more accurately the probabilities of process paths are calculated, but the duration of the simulation will increase accordingly.*Working days per year*and*Working hours per day*are used to calculate required resources and aggregate time values.*Working hours per day*are expressed in decimal hours (for example, 7 hours and 30 minutes = 7.5).For more information on these parameters, click the buttons next to the boxes.

Click

*Start*.

Checks are run to find out if the model is ready for simulation. The results of the checks are shown in the "Validation" widget at the right side of the program window.

If no errors are found, the simulation results will be generated. When the calculation has finished, the simulation results are displayed.

**Compare As-Is and To-Be Models**

In addition to simulating one specific process, you can directly compare different variants of models. This allows you to test changes and work out where improvements are needed. To start a simulation with multiple models:

Select two or more models in the Model Catalogue.

Right-click the selection, and then click

*Simulation*.

**Advanced (Different Business Hours and Working Hours)**

Select this option if the business hours of your company and the
individual working hours are different. You must define the following
*simulation parameters*:

In the

*Working days per year (employee)*box, type the average number of days in a year in which an employee is performing work.In the

*Working hours per day*box, type the average number of hours per day in which an employee is performing work.In the

*Business days per year (company)*box, type the number of days in a year in which business is conducted and processes are executed.In the

*Business hours per day (company)*box, type the number of hours per day in which business is conducted and processes are executed.

If a company operates non-stop (24/7/365), one day lasts 24 hours and this time should be considered when calculating process cycle time. However, employee's work time is typically 8 hours/day, which means that 24 working hours are equal to 3 working days of an employee and this result is used when calculating personnel requirements.

## Interpret the Simulation Results

Once the simulation is complete, you can examine the results. By default, an overview of the results is displayed. Additional tabs provide more detailed information.

The following four tabs are available for evaluating and analysing the results:

An overview of the simulation results.

Drill-down to see how costs are accumulated at each activity. Supports Activity-based Costing (ABC).

How many full-time employees need to be allocated to this process? Full Time Equivalent (FTE) calculation tool.

Find out which paths lead to which process results and how often they occur. Enables detailed analysis of process paths in terms of time and cost (critical paths, number of paths, expensive paths, etc.). Also offers the possibility to display the paths graphically in the model.

### Types of Results Data

Each simulation provides the following results (spread over the four simulation tabs):

**Execution time**Specifies the average time necessary for completing activities.

**Waiting time**Specifies how much time is needed on average as waiting time prior to execution of activities or while activities are interrupted.

**Resting time**Specifies the average time in which activities "rest" after execution.

**Transport time**Specifies the average time necessary for transport between the execution of different activities.

**Cycle time**Specifies how much time is needed on average from the start of a process to its end (in other words, the response times to customers for customer-related processes).

**Non-personnel costs**Specifies the costs of executing activities (not related to the wages of process performers).

**Personnel costs**Personnel costs are calculated by multiplying the

*Execution time*of a*Task*by the*Hourly wage*of the assigned*Role*.ExampleThe

*Execution time*of all*Tasks*in the process "Thorough Security Check" is 15 minutes (= ¼ hour). The employee who performs the*Role*"Airport Security" is paid "20 EUR" (currency is implicit) per hour. The total personnel cost per process is 5 EUR (¼ x 20).**Total costs**For the total costs, non-personnel costs and personnel costs are added together.

**# executions**The (average) number of executions of activities.

**Capacity**Calculated number of full-time employees with the given role needed to perform activities within a given time period. This number assumes that an employee is performing only tasks in the simulated process, without any overheads (depending on working hours per day).

ExampleThe process "Thorough Security Check" takes place 100 times every day. The

*Execution time*of all*Tasks*in this process is 15 minutes (= ¼ hour). The number of full-time employees needed to perform this process is 3,125 [(100 x ¼) : 8], if "8" is the default value for*Working hours per day*.**Probability**The probability of an

*End Event*occurring in percent (%).

### Show Average Results per Hour, Month, Year or Process

In all simulation tabs, you can view results per process or for all processes over a time period:

To display the average results per process, click the

*per process*button.To display results for all processes, click either the

*per year*,*per month*or*per day*buttons.

For the calculation of the results for all processes, the following factors all have an impact:

the

*Quantity*and the*Time period*defined in the*Process Start*the

*Working days per year*and*Working hours per day*selected when starting the simulationthe observation period selected in the result table (

*per year*,*per month*or*per day*)

The process "Thorough Security Check" takes place 100 times every day.
The personnel cost per process is 5 EUR. The total personnel cost per
day is 500 EUR (5 x 100). The total personnel cost per year is 110,000
(250 x 220), if "220" is the default value for *Working days per year*.

### Overview

This tab provides an overview of the simulation results. The simulation results are displayed as follows:

Average results per process or for all processes over a time period are displayed in a table. The result table contains one line for every simulated process. The following information is displayed:

Average process times

Average process costs

Additionally, key metrics are represented graphically below the table:

If you only simulate one specific process, this data is represented in a pie chart.

If you simulate multiple models, key metrics are represented by a bar chart. This is especially useful for comparing As-Is and To-Be models, as you can see at a glance which variant performs better.

You can drill-down to see how costs are accumulated at each *Task* and
which activities are often performed.

In the result table, the activities are listed. They are grouped by
model, and sorted according to the order in the model. Each model in the
simulation is listed with all activities, including sub models which are
referenced from a *Subprocess*. The following information is displayed:

Responsible roles

Number of executions

Times

Costs

### Capacity

The *Capacity* tab provides detailed information for personnel planning.
You can find out how many full-time employees with the given role are
needed to perform a process within a given time period.

In the result table, the *Roles* are listed. They are grouped by model,
and sorted alphabetically. Each model in the simulation is listed with
all *Roles*, including sub models which are referenced from a
*Subprocess*. The following information is displayed:

*Name*column, click the button , and then click group by this field.

In this view, you can find out how much in total each *Role* is needed.

### End Events & Paths

The *End events & paths* tab allows you to analyse *End Events* to see
how often process results occur. This will enable you to answer
questions such as:

How many job applications per year do I accept and how many do I reject?

How many credit requests per month do I accept and how many do I reject?

How many times does a product not meet quality requirements?

In the result table, the *End Events* are listed. They are grouped by

the

*Process*the

*End Event*the

*Time Period*you want to analyse

Select Time Period: Per Process vs. Single Path ResultsTo display the average results per process, select

*per process*.To display the exact results for a path run, select

*single path results*.

All paths leading to the selected process end are displayed. For each path, you can see the probability of it occurring, and the times and costs associated with it. Use the sorting options to find out which path is the most critical, longest, shortest, most likely, most expensive, etc.

**Visualise Path**

To visualise a path in a model:

- Click the link to the path in the result.

The model is opened in the graphical editor. The objects that match this path are highlighted on the drawing area. Numbers indicate how often a step was executed (useful for loops).

Alternatively, you can show the path as a list:

- Click the
*Show path flow*button next to the link.

**Sort Table Contents**

By default, the paths are sorted alphabetically. To change this sorting, proceed as follows:

Costs

Below, in the *capacity* table, you can see how many full-time employees
with the given role are needed to perform the process assuming the *End
Event* occurs a certain number of times.

At the bottom, in the *cost driver* table, you can see the total times
and costs to perform the process assuming that the *End Event* occurs a
certain number of times (first row) or once (second row).

## Advanced Methods

This section explains advanced methods for defining transition conditions.

### Limit Number of Loops

When a process contains loops, you can assign different probabilities
for consecutive executions of the loops. This enables you to specify
that the chance that a *Task* will be completed successfully increases
(or decreases) with each run.

**Attribute Requirements**

To define the probability of alternative paths starting from an

*Exclusive gateway*, adapt the*Transition condition*attributes of the outgoing*Sequence flows*.Transition conditions are represented by floating point numbers

`≥`

0 and`≤`

1 (e.g. 0.7). The sum of the probabilities of all alternative paths starting from a gateway has to be 1.For loops, assign more than one probability, so that the value changes after consecutive executions. Separate the values with a ";". The simulation runs through the loop the first time with the first values, then with the second values and so on.

You want to specify that the probability of finding new errors during a document review decreases each time a revised version is made available to the reviewers:

On the first run, the path "Quality OK? = yes" is selected in 20% of the cases, and the path "Quality OK? = no" selected in 80% of the cases.

On the second execution, the path "Quality OK? = yes" is selected in 90% of the cases, and the path "Quality OK? = no" selected in 10% of the cases.

On the third execution, the path "Quality OK? = yes" is selected in 100% of the cases, and the path "Quality OK? = no" selected in 0% of the cases.

Set *Transition condition* to "0.2;0.9;1" for the first *Sequence flow*
and to "0.8;0.1;0" for the second *Sequence flow*.

### Decide Process Path Based on Dependent Probabilities

Recurring transition values can be defined via variables. To determine paths in a process, the same variable value will always be used after branchings. This way, it is possible to define depending probabilities.

**Attribute Requirements**

To define a variable, select a

*Sequence flow*in the process. Click the icon to add a new row in the attribute*Variables*. Specify the name (first column), distribution type (second column) and the distribution parameters (third column).To use the variable for alternative paths starting from an

*Exclusive gateway*, adapt the*Transition condition*attributes of the outgoing*Sequence flows*. Specify the variable name, an operator and a constant.

Defining all variables in a *Sequence flow* at the beginning of the
process makes it easier to find them when a change is necessary.

For more information on these parameters, click the buttons next to the attributes.

You want to specify that the simulation selects either new customer or existing customer when making decisions in the process.

In the first decision, the path "New customer = Yes" is selected in 80% of the cases, and the path "New customer = No" selected in 20% of the cases.

In the second and each subsequent decision, the same variable value will always be used.

Create a new *Variable* "Newcustomer", "Discrete", "Yes (0,8); No
(0,2)". Set *Transition condition* to "Newcustomer=Yes" for all
*Sequence flows* that comprise the "new customer path", and to
"Newcustomer=No" for the *Sequence flows* that comprise the "existing
customer path".

### Probability Distributions

In this section, we are going to take a closer look at the probability distributions that can be used to specify the probability of alternative paths during process simulation. The following probability distributions are possible:

**Discrete Distribution**In discrete distributions, each variable assumes a fixed (discrete) value.

**Continuous Distribution**Normal distribution, exponential distribution and uniform distribution. In continuous distributions, the focus is on intervals (a range of values which the variable can assume).

Probability distributions are defined via variables.

**Attribute Requirements**

To define a variable, select a

*Sequence flow*in the process. Open the Notebook and select the chapter "Simulation data". Click the icon to add a new row in the attribute*Variables*. Specify the name (first column), distribution type (second column) and the distribution parameters (third column).To use the variable for alternative paths starting from an

*Exclusive gateway*, adapt the*Transition condition*attributes of the outgoing*Sequence flows*. Specify the variable name, an operator and a constant. Two or more variables can be logically joined using the logical operators AND and OR.

#### Discrete Distribution

A discrete distribution has a finite number of values.

**Notation in ADONIS**

In order to define a discrete distribution, enter two or more symbols with their corresponding probabilities. The sum of the probabilities must always equal 1.

For example, the *Variable* "VariableX", "Discrete", "Normal case (0.4);
Exception1 (0.3); Exception2 (0.3)" is assigned the value "Normal case"
with a probability of 40%, and the values "Exception1" and "Exception2"
with a probability of 30% each.

See Decide Process Path Based on Dependent Probabilities for an example of a discrete distribution.

#### Normal Distribution

The normal distribution (or Gaussian distribution) is the most important type of continuous probability distribution.

**Notation in ADONIS**

In order to define a normal distribution, two parameters are needed: the expected value and the standard deviation.

For example, the *Variable* "VariableX", "Normal", "0\@2" has a normal
distribution with an expected value of 0 and a standard deviation of 2.

Damages asserted through household insurance are subject to the normal distribution with a mean of 100 EUR and a standard deviation of 20 EUR. For claims up to and including 90 euros, claims settlement is initiated directly. Claims over 90 euros are subject to an audit. What is the probability that a claim is settled directly?

- The first path is selected if the claim is smaller than or equal to 90 EUR, and the second path if the claim is greater than 90 EUR.

Create a new *Variable* "Claimamount", "Normal", "100\@20". Set
*Transition condition* to "Claimamount<=90" for the first *Sequence
flow* and to "Claimamount>90" for the second *Sequence flow*.

#### Exponential Distribution

The exponential distribution is a continuous probability distribution over a set of positive real numbers. It is often used to model the time elapsed between events.

**Notation in ADONIS**

In order to define an exponential distribution, enter the value of the exponential distribution, which is 1 divided by the expected value (1/E).

For example, the *Variable* "VariableX", "Exponential", "0.5" has an
exponential distribution with an expected value of 2.

On average, customers spend 2 minutes in a call centre queue. If they have to wait for more than 3 minutes, the telephone queue management offers customers the option of an automatic callback at a set time. What is the probability that a customer will have to wait for more than 3 minutes?

- The first path is selected if the waiting time is less than or equal to 3 minutes, and the second path if the value is greater than 3 minutes.

Create a new *Variable* "Waitingtime", "Exponential", "0.5" (1/E = 1/2).
Set *Transition condition* to "Waitingtime<=3" for the first
*Sequence flow* and to "Waitingtime>3" for the second *Sequence
flow*.

#### Uniform Distribution

The uniform distribution describes a probability distribution in which the same probability of being true exists for all values between an upper and a lower limit.

**Notation in ADONIS**

In order to define a uniform distribution, enter the boundaries for the uniform distribution where the first number is the lower boundary and the second number is the upper boundary.

For example, the *Variable* "VariableX", "Uniform", "20\@100" has a
uniform distribution between 20 and 100.

The ADOMoney Bank offers loans between 10,000 EUR and 500,000 EUR. For loans of more than 100,000 EUR, additional tasks have to be executed in the process flow. The number of loans in the portfolio is (approximately) uniform for each loan amount. What is the probability that the value of a loan is greater than 100,000 EUR?

- The first path is selected if the value of a loan is greater than or equal to 100,000, and the second path if the value is less than 100,000.

Create a new *Variable* "Amount", "Uniform", "10000\@500000". Set
*Transition condition* to "Amount>=100000" for the first *Sequence
flow* and to "Amount<100000" for the second *Sequence flow*.

## Export Simulation Results
