Currently I’ve sent by my office to Singapore for a Short Term Assignment (STA). Since I heard that this city has a good offer on electronic device, so I’m considering buying a gadgets here
In this blog, I will try to use Non-compensatory Models for 2 types as below:
- Disjunctive Resolution
The gadget that will be choose is Apple iPhone 4, Apple iPad 2 and Samsung Galaxy Tab
There several things that must be consider, such as:
Analysis & Comparison of Alternatives
A. Disjunctive Resolution
This method is similar with satisficing method, because attributes will be compares to some standard measurement. The different is, this method will evaluate each alternatives on the best value achieved for any attributes. If an alternative has just at least one attribute that meets or exceed the standard, that alternative is kept.
By applying this method, alternative B is has a big probability to be taken out from buying consideration. This left us 2 alternatives, Gadget A and C that need to be considering buying. But since gadget C has 4 best values than alternative A, than we can decide that alternative C is the chosen alternative.
On this method, each attributes will be compared on one to another. The alternative which has the highest value for the most important attribute is then chosen as the best alternative. But when two or more alternatives has identical values for the most important attributes, then the 2nd most important attribute must be specified and used to break the deadlock. This will keep continued until all the alternatives have been evaluated.
On below table, I have compared each attributes to another and ranked them according to the number of times it appears on the left hand side of the comparison. It turns out that “Feature” is the most important attributes that I considered on choosing a boarding house. The 2nd important is “Price” and followed by “Memory” and “Battery”. Size is really are just an additional consideration and least important among others attributes.
Now, on below table we compare each alternative on each attributes to decide which boarding house is the best one. We will start on the most important attributes which is “Feature”. On this attributes alternative C is the best one. This result is also shown from attributes “Price”, “Battery” and “Size”, only attribute “Memory” that alternative C is lack in. Therefore we can decide, from this method the chosen one is Alternative C.
Selection of preferred Alternatives
In summary, by using Multi-Attributes Decision Making especially on Noncompensatory Models, we can decide that Samsung Galaxy Tab is the best alternative.
Performance Monitoring & Post Evaluation of Result
Make sure that the gadget work as in specification especially for battery and the feature offered.
The warranty and after sales service must be ensure to anticipate any future damage.
