I am tired from a long week of work/school and have a free weekend ahead. I want to choose an activity that will help you relax and recharge effectively.My budget for activities is limited.

Input Factors ：

I will evaluate my options based on these three factors:

1. Cost:How much money will the activity require?

2. Energy Level:How much physical/mental energy does the activity need?

3. Enjoyment:How much do you personally expect to enjoy the activity?

Output Factors (Alternatives):

1. Option A: Go Hiking

2. Option B: Binge-Watch a TV Series

3. Option C: Go to a Nice Restaurant with Friends

1. Scenario of Decision

You want to choose the most suitable mobile phone among available options. The decision depends on several important features (price, camera, storage, looks), and the goal is to determine how suitable each mobile is based on your preferences.

2. Input Criteria

The decision is based on four main input factors:

• Price → (e.g., low, medium, high)

• Camera Quality → (e.g., poor, average, excellent)

• Storage Capacity → (e.g., small, medium, large)

• Looks/Design → (e.g., unattractive, normal, stylish)

3. Output Criteria

The final decision is expressed as Mobile Suitability → (e.g., unsuitable, acceptable, good, very good, excellent).

4. If–Then Rules in Our Brain (Fuzzy/Heuristic Rules)

These are the mental rules we often use subconsciously. Examples:

• Rule 1: IF price is low AND camera is excellent THEN mobile suitability is high.

• Rule 2: IF price is high AND storage is small THEN mobile suitability is low.

• Rule 3: IF camera is excellent AND storage is large AND looks are stylish THEN mobile suitability is very high.

• Rule 4: IF price is medium AND camera is average AND storage is medium THEN mobile suitability is acceptable.

• Rule 5: IF price is low BUT looks are stylish THEN mobile suitability is moderate.

• Rule 6: IF price is high AND camera is excellent AND storage is large THEN mobile suitability is excellent.

1. Scenario

You plan to buy a new laptop. One is a high - end model with great performance, and the other is an affordable one with basic functions.

2. Input Factors (criteria)

Performance: The high - end laptop has a fast processor, more RAM, and a better graphics card, good for gaming and video editing. The affordable one has just enough power for simple office work and web browsing. 

Price: The high - end laptop is costly, while the affordable one is much cheaper. 

Portability: The high - end laptop is heavy and thick, and the affordable one is light and thin, easier to carry. 

3. Output Factors (alternatives)

Alternative 1: Buy the high - end laptop 

Alternative 2: Buy the affordable laptop 

4. Rules (how you think about the options)

Need - based Comparison: First, check your real needs. If you often do tough tasks like gaming or video editing, performance is key. 

Cost - Benefit Analysis: Compare the price with the features and performance. If the extra performance of the high - end laptop isn't worth the high price for you, choose the affordable one. 

2.Input Factors (criteria):size,weight,price

3.Output Factors (alternatives):suitable, unsuitable

4.Rules (how you evaluate your options in your brain):

If the size, weight and price of this frisbee are moderate, it is suitable.

If the size of this frisbee is large or small, this frisbee is unsuitable.

If the the weight of this frisbee is large or small, this frisbee is unsuitable.

If the the price of this frisbee is large or small, this frisbee is unsuitable.

2.Input Factors (criteria):

color(green,yellow),

shape(round,long)

3.Output Factors (alternatives):

taste(very good,good,bad,very bad)

4.Rules (how you evaluate your options in your brain):

If the color is yellow and the shape is long then taste is very good.

If the color is green and the shape is round then flavour is very bad.

If the color is yellow and the shape is round then flavour is good.

If the color is green and the shape is long then flavour is bad.

I want to buy a portable laptop.

Input Factors (Criteria):

1. Performance: Processor > Memory > Storage

2. Price

3. Brand

4. Portability: Weight > Battery life

5. Appearance

6. Additional features

7. After-sales service

Priority Order (High → Low):

1. Performance (CPU > Memory > Storage)

2. Price (as low as possible, under the condition that performance is sufficient)

3. Brand (reputation and warranty service)

4. Portability (weight and battery life)

5. Appearance and additional features (bonus factors)

Decision Rules (Logic):

1. If performance is insufficient → eliminate directly

2. If performance is sufficient → choose the lower-priced option

3. If prices are similar → choose the better brand

4. If brands are similar → choose the lighter and longer-lasting one

5. If all the above are similar → then consider appearance and additional features

1. Scenario of Decision

You want to choose the best game to play with friends this weekend. The decision is based on key factors like cost, difficulty, and fun level. The goal is to pick the most enjoyable game for the group.

2. Input Criteria

The decision is based on these main factors:

- Cost (Free, Cheap, Expensive)

- Difficulty (Easy, Medium, Hard)

- Fun with Friends (Boring, Fun, Hilarious)

3. Output Criteria

The final decision is:

Game Choice (Bad Choice, Okay Choice, Good Choice, Great Choice)

4. If-Then Rules

- Rule 1: If cost is free and fun is hilarious then choice is great choice.

- Rule 2: If cost is expensive and difficulty is hard then choice is bad choice.

- Rule 3: If fun is fun and difficulty is easy then choice is good choice.

- Rule 4: If cost is cheap and fun is boring then choice is okay choice.

- Rule 5: If difficulty is medium and fun is fun then choice is good choice.

Input Criteria

The decision is based on seven main input factors:

•Performance → (e.g., poor, average, good, excellent)

•Price → (e.g., low, medium, high)

•Brand → (e.g., unknown, normal, reputable, top)

•Portability → (e.g., heavy/short battery, medium, light/long battery)

•Appearance → (e.g., unattractive, normal, stylish)

•Additional Functions → (e.g., none, some, many)

•After-sales Service → (e.g., poor, acceptable, good)

Output Criteria：The final decision is expressed as:

Laptop Suitability → (e.g., unsuitable, acceptable, good, very good, excellent).

Rules：

•Rule 1: IF performance is poor THEN laptop suitability is unsuitable.

•Rule 2: IF performance is good AND price is low THEN laptop suitability is high.

•Rule 3: IF performance is excellent AND brand is reputable THEN laptop suitability is very good.

•Rule 4: IF portability is light/long battery AND brand is top THEN laptop suitability is excellent.

•Rule 5: IF all factors are similar, THEN appearance and additional functions can improve suitability slightly.

Step 1: construct the pair-wise comparison matrix

Step 2: compare the criteria with your defined scale

Step 3: converts the numbers to decimal

Step 4: Normalize the matrix

Step 5: obtain the weights of criteria
