HOW TO USE MULTI OBJECTIVE OPTIMIZATION

1

• PRESENTATION
• ON
• MULTI-OBJECTIVE OPTIMIZATION ON THE BASIS OF
  RATIO ANALYSIS
• (MOORA)
• BY
• AYEWOH ABIDEMI VICTOR

2

• INTRODUCTION
• The MOORA method is one of the different MCDM
  techniques
• It was introduced by Brauers in 2004
• MOORA is a compensatory method (desirable and
  undesirable criteria) used simultaneously
• It is considered as an objective method

3

• APPLICATION OF MOORA
• Selection of Contractors
• Selection of Suppliers
• Composite Material Selection
• Site Selection for Car Sharing Station
• Operational Health and Safety Risk Analysis

MCDM METHODS COMPUTATIONAL TIME SIMPLICITY MATHEMATICAL CALCULATIONS
MOORA Very Less Very Simple Minimum
AHP Very High Very Critical Maximum
ANP Moderate Moderately Critical Moderate
VIKOR Less Simple Moderate
ELECTRE High Moderately Critical Moderate
TOPSIS Moderate Moderately Critical Moderate
PROMTHEE High Moderately Critical Moderate
Comparison of MOORA with other MCDM approaches

• ADVANTAGES OF USING MOORA
• MOORA is one of the simplest multi-criteria
  method in selecting the corresponding decision
  attribute
• Compared with other MCDM methods, MOORA is highly
  specific in decision making
• MOORA chooses an optimal alternative within less
  computational time and simple mathematical
  calculations when compared to DEA, AHP, TOPSIS,
  PROMTHEE ELECTRE
• MOORA performs simultaneous optimization on two
  or more conflicting attributes

6

• STEPS TO COMPLETION OF MOORA
• STEP 1 Create a Decision Matrix
• X11 X12 X1n
• Xij X21 X22 X2n
• Xm1 Xm2 Xmn

7

• STEP 2
• Normalize the Decision Matrix
• Xij Xij/ ?? ?? (?????? 2 )

8

• STEP 3
• Multiply the Xij by the Weight

9

• STEP 4
• OPTIMIZE ATTRIBUTE
• Yi ?? ?? ??????(????) - ?? ?? ??????(????)
  
• (Beneficial Attribute Non/Beneficial Attribute)

10

• STEP 5
• TAKE THE ORDINAL RANK OF Yi
