PROCESS SIMULATION MODEL DISCOVERY SYSTEM OF OUTPATIENT CONSULTATION AND PROCESS SIMULATION MODEL DISCOVERY METHOD

1 . A process simulation model discovery system of outpatient consultation, comprising:

an event log collection unit which collects an event log data;

a data pre-processing unit which removes a duplicate value and an outlier from the log data;

a data analyzing unit which derives from a process from the log data and analyzes a working time; and

a process simulation modeling unit which generates a process simulation model,

wherein the data analyzing unit includes a process derivation module which derives a process corresponding to a work from a log data and a working time analyzing module which derives a working time for a patient from the log data.

2 . The system of claim 1 ,

wherein the data pre-processing unit includes a missing value processing module which processes a missing value in which a data is missed, and the missing value processing module generates a missing value by modifying a worker's ID to be equal to an ID of department in which the worker is included.

3 . The system of claim 1 ,

wherein the process derivation module connects one log to another log through a movement line and sets up only logs connected with more than a predetermined number of a movement line as a process.

4 . The system of claim 1 ,

wherein the data analyzing unit includes an arrival rate analyzing module which derives an arrival rate (AR) that is a difference between a reservation time and an arrival time, and

the arrival rate analyzing module derives the arrival rate by using the following equation:

AR=π rt ( e i )−π a (π trace (1)),

Wherein, π rt (e i ) is a reservation time, and π a (π trace (1)) is a working time when a patient who arrives at the hospital firstly performs.

5 . The system of claim 1 ,

wherein a working time analyzing module derives an operation time (OT) for a patient, and the operation time (OT) satisfies the following equation:

OT=π et ( c dk )−π et ( c dj ),

Wherein, π et (c dk ) is the ‘d’ operation processing time against the ‘k’ patient, π et (c dj ) is the ‘d’ operation processing time against the ‘j’ patient, and the ‘j’ patient is a patient treated just before the ‘k’ patient.

6 . The system of claim 1 ,

wherein the working time analyzing derives a waiting time (WT) that is a patent's waiting time for the treatment, and the waiting time (WT) satisfies the following equation:

WT=π et ( c dj )−π et ( c ck ),

Wherein, π et (c dj ) is the ‘d’ operation processing time against the ‘j’ patient, π et (c ck ) is the ‘c’ operation processing time against the ‘k’ patient, and the ‘c’ operation is an operation performed to the ‘k’ patient just before the ‘d’ operation.

7 . A process simulation model discovery method of outpatient consultation, comprising:

event log collecting which collects an event log data;

data pre-processing which removes a duplicate value and an outlier from the log data;

data analyzing which derives from a process from the log data and analyze a working time; and

process simulation modeling which generates a process simulation model,

wherein the data analyzing includes process deriving which derives a process corresponding to a work from a log data and working time analyzing which derives a working time for a patient from the log data.

8 . The method of claim 7 ,

wherein the data pre-processing includes a missing value processing which processes a missing value in which a data is missed, and the missing value processing generates a missing value by modifying a worker's ID to be equal to an ID of department in which the worker is included.

9 . The method of claim 7 ,

wherein the process deriving connects one log to another log through a movement line and sets up only logs connected with more than a predetermined number of a movement line as a process.

10 . The method of claim 7 ,

wherein the data analyzing includes an arrival rate analyzing which derives an arrival rate (AR) that is a difference between a reservation time and an arrival time, and

the arrival rate satisfies the following equation:

AR=π rt ( e i )−π a (π trace (1)),

Wherein, π rt (e i ) is a reservation time, and π a (π trace (1)) a working time when a patient who arrives at the hospital firstly performs.

11 . The method of claim 7 ,

wherein a working time analyzing derives an operation time (OT), and the operation time (OT) satisfies the following equation:

OT=π et ( c dk )−π et ( c dj ),

Wherein, π et (c dk ) is the ‘d’ operation processing time against the ‘k’ patient, π et (c dj ) is the ‘d’ operation processing time against the ‘j’ patient, and the ‘j’ patient is a patient treated just before the ‘k’ patient.

12 . The method of claim 7 ,

wherein the working time analyzing derives a waiting time (WT), and the waiting time (WT) satisfies the following equation:

WT=π et ( c dj )−π et ( c ck ),

Wherein, π et (c dj ) is the ‘d’ operation processing time against the ‘j’ patient, π et (c ck ) is the ‘c’ operation processing time against the ‘k’ patient, and the ‘c’ operation is an operation performed to the ‘k’ patient just before the ‘d’ operation.
