Consumers' Profile Monitor - Based on Organizational Responsibility Model (Passos, Chamovitz & Theodoulidis, 2013)

@#$#@#$#@
## WHAT IS IT?

Consumers Profile Monitor is an simple adaptation from Evolution Employee, designed for The Organisational Responsibility Model (Passos, Chamovitz and Theodoulidis), which was built based  on the Aging Chains model proposed by John Sterman in the book Business Dynamics: Systems Thinking and Modeling for a Complex World.

Original model had been constructed to help managers to monitor status of 3 types of employees: Trainees, Common Employees and Masters, during employee life cycle.  

Staff evolution model mapped the evolution of professionals' careers, taking into account PROMOTION and OUTFLOW along employee life cycle, from hiring up to retirement.

Consumers Profile Monitor considers 3 TYPES OF CONSUMERS: BEGINNERS, COMMON AND MASTERS .ere is a DELAY that makes the employee takes certain time to pass from beginner to more experienced positions. There is also ANOTHER DELAY for the employee to pass from the last employee stage, master, to finish his career at that company. The closure can be prematurely finished, along the intermediate stages.

The model was adapted from the original to allow SHORT-TERM OR LONG-TERM LEAVES, and the  main consequence is  the consequent delay for their evolution/promotions,  causing the employee to remain longer at each stage.

Agent Based Modelling allows modelling each agent individually. For this model there is a  PROBABILITY for each different agent leaving the company,  as well as a different TIME for the agent to STAY TEMPORARY OUT of the company. 

The model then allows the manager to perform simulations changing parameters until he gets to a number of hires that allows, through the replacement of staff, to keep company with a suitable  crew to keeping running it's services. 


## HOW IT WORKS

Suppose there is a place where a product need to be tested in a specific population from a limited and closed region. For this model, no new clients are considered, since there is a specific period to test the product (for example 35 weeks). 

This product can have 3 distinct types of consumers.  As they get older, they can change their behaviour. One example could be an anti-aging cosmetic. 

AGENTS (consumers) can assume different STATUS:
 
  Beginners          (B) is true when the agent is a beginner 
  Common Consumers   (C) is true after beginners upgrade
  Masters            (M) is true after Employee upgrade 

When the test starts, no new consumers enter the system. However, customers can stop   to consume (they are OUT OF MARKET) for a short or long time, due to a trip, a disease, or other cause.

When an AGENT is OUT OF THE MARKET, status assume values as follows:  
                              
  Beginners_OutOfWork   (T)  is true if beginner is is out 
  Beginners_OutOfWork   (C)  if true if common consumer is out  
  Beginners-OutOfWork   (M)  is true if master is out  

The test starts with all consumers being beginners and no one out of company. 

Along the time, the 3 groups of agents (B, M, C) upgrade their status.

- fraction-1   - determiines a fraction from the quantity of beginners that will be upgraded 
delay-promotion-1 - defines how long (weeks) does it takes to be upgraded from B to C
       
- fraction-2   - determines a fraction from the quantity of common employees that will be upgraded 
delay-promotion-2 defines how long (weeks) does it takes to be promoted from C to M 

- fraction-T  - ramdomically gives the number of beginners that were away that year
delay-T     - ramdomically gives the number of beginners that came back to the market  after being away  

- fraction-C  - ramdomically gives the number of common consumers that were away that year
delay-C     - ramdomically gives the number of common consumers that came back to the market  after being away  

- fraction-M  - ramdomically gives the number of masters that were away that year
delay-M     - ramdomically gives the number of masters that came back to the company after being away  

delay-retirement   - defines the number of masters that left definitely the market.  



 
Whilst AGING, 

- part of each group will be UPGRADED - 
how many: (Consumer / delay-promotion ) * fraction 
("1" controls promotion and delay from B to C and 2 controls promotion from C to M ) 

- the other part of each group that is not away and REMANIN CONSUMING, IN MARKET  - 
how many: ( Employee / delay-promotio ) * ( 1 - fraction )

- part of each group will LEAVE TEMPORARY  the market (i.e. on license, illness) - 
how many: (  Employee * fraction ) 

- part of each group will RETURN TO THE MARKET  - 
how many: (  Beginner_OutOfWork / delay  )

  
## HOW TO USE IT

select the number of new consumers (beginners) are entering the market for the test. 
Than try to change fraction_1 consider a test after a period and  part of them will not be promoted, only X %.  
Run the model and observe the graphic. 
Do the same with fraction_2
Run the model again and observe the graphic. 


## THINGS TO NOTICE

- As the responsibility model, the sum of parameters: delay_promotion_1  + delay_promotion_2 + delay_retirement is 35 weeks, but it can be changed).

Consider, for start: 

- delay_promotion_1 = 2; delay_promotion_2 = 4; delay_retirement = 29 years.

These parameters reflect the opportunity that the company offers for public workers for  building a career for life in the company. Nowadays  the profile of the youth follows a different behavior, they does not think of staying in the same organization for all his life.
 
- Fraction 1 and 2 represent the percentage of people who are expected to leave the company. It suggested 20% for promotion from beginners to common employees and  10% for promotion from common employees to masters. 

  This parameter reflects consumers' fidelity stability. Some consumers stop to buy products and return, after a time. 
 
- Fraction T, C and M indicate the percentage of consumers that stay temporary out of the market.
  These parameters reflect the state of health of the population (consumers), if a region quite unhealthy this value can be high. Consider a coal mine, for example. 
      
 - Delay T, C and M indicate the time of consumers being away.
  These parameters reflect two things:
       1) high if the health status of the population is very poor, an important point may be the HDI of the region.
       2) low if it is an university region,  due to Masters, PhDs, Post-docs or Sabbatical year in some cases.

## THINGS TO TRY

Modify the main parameters and compare the graphics, and the final results. 

## EXTENDING THE MODEL

This model was  extended from Production and Business Management to the Market field, to monitor consumers behaviour.
