| + | * How many cases, events and event classes the log contains? | ||
| + | * How long is the longest trace and how short is the shortest trace in the log? | ||
| + | * What is the meaning of colors in the explorer in the log inspector? | ||
| + | * Which event and which resource occurs most often? | ||
| - | Then click "start analyzing this log" (or in other versions: play arrow), and then select one of the algorithms (double-click). \\ | + | {{:pl:dydaktyka:bim:lab4_2014:logwprom.png?475|}} |

| + | Select one of the algorithms (double-click). | ||
| + | |||
| + | Depending on the version of ProM, check the results of applying various miners, such as (note that not every miner can be available in your version of ProM): | ||
| + | * Alpha Miner (Alpha Algorithm Plugin / Alpha Miner) | ||
| + | * Inductive miner, | ||
| + | * Fuzzy miner, | ||
| + | * Heuristic Miner, | ||
| + | * Genetic Miner. | ||
| + | |||
| + | Most of these miners generate some kind of process model, which can be represented in various formats, e.g.: | ||
| + | * heuristic net (very simple process map), | ||
| + | * workflow net or Petri Net, | ||
| + | * BPMN model. | ||
| For some algorithms, setting some additional options are required.

| + | BPMN is an OMG standard for process modeling. \\ | ||
| + | During this class, we will discuss the basic workflow representation in BPMN language.\\ | ||
| + | Below a simple BPMN process shows the basic elements of the BPMN notation: | ||
| + | |||
| + | {{:pl:dydaktyka:dss:lab:bpmn-model-elements.png?700|}} | ||
| + | |||
| + | First, Task 1 is performed. Then, either Task 2a or Task 2b is performed. | ||
| + | Next, Subprocess is performed. After the subprocess, Task 3a and 3b are performed in parallel (this does not mean that they have to be performed at the same time). | ||
| + | |||
| + | To obtain a BPMN model, you can use converters to BPMN from most mined models. \\ | ||
| + | In some versions of ProM, a BPMN miner which directly discovers a BPMN model is available. | ||
| + | |||
| + | Moreover, a business process can also specify who (which department, role, user, participant) should perform a particular taks (see the example below): | ||
