1. Problem Definition
Further to the previous W3 blog in which Grid Analysis had been applied to figure out the alternative in moving to new place.
2. Development of Feasible Alternatives
Investment options are:
3. Development of the Outcome for Alternative
- Rent price
4. Selection of Criteria
|Price||100,000 R.O||80,000 R.O||150,000 R.O|
|Rent price/year||12,000 R.O||13,200 R.O||7,200 R.O|
There are four noncompesatory models to be tested:
|Town-House Vs Apartment||Town-House Vs House||House Vs
|Market / Demand||Equal||Better||Better|
|Feasible Ranges for Satisfactions|
|Market / Demand||–||Better||None|
|Rent price/year||12,000 R.O||13,200 R.O||None|
C. Disjunctive Resolution
|A-Result of Paired Comparison|
|Location > Price||(Location is more important than Price)|
|Demand > Price||(Demand is more important than Price)|
|Rental Price > Price||(Rental Price is more important than Price)|
|Location > Demand||(Location is more important than Demand)|
|Location > Rental Price||(Location is more important than Rental Price)|
|Rental Price > Demand||(Rental Price is more important than Demand)|
|Price||0||Apartment > Town house > House|
|Location||3||Apartment > Town house > House|
|Demand||1||Apartment = Town house > House|
|Rental Price||2||Apartment > Town house > House|
5. Analysis and Comparison of the Alternative.
- Dominance: is useful only for excluding one of lower alternative, which is House.
- Satisficing: when the alternatives are acceptable this tool become not good enough for decision-making.
- Disjunctive Resolution: Best attribute is Apartment, as evaluated above.
- Lexicography: Apartment will be the best choice.
6. Selection of the Preferred Alternative.
The disjunctive resolution has shown as another method in eliminating the best alternatives when using the 4 models
7. Performance Monitoring and the Post Evaluation of Result.
As evaluated and weighted above the disjunctive resolution method has brought Apartment as the best alternative.
