TEACHER’S COMMENT:

CHAPTER 1: LINEAR PROGRAMMING

1 Set up an algebraic model - which clearly states the Solution, Problem Objective, and Constraints.

 Root

- LT: The number of batches of large type – 1 color

- ST: The number of batches of small type – multicolor

LT = ?; ST = ?

Max (4700000L + 5900000S) = ?

- Cutting time: 0,3L+0,25S <= 60

- Firing time: 0,27L+0,58S <= 105

- Glazing time: 0,16L+0,2S <= 40

- Material: 32,8L+20S <= 6000

- L,S >= 0

2 Solve

4 Conclusion.

Following the solved result, this company should produce 56,7 batches of large brick (5670 bricks) and 154.64 batches of small brick ( 15460 bricks) to achieve maximum profit is

1,178,865,979 VND and fit the plan they want.

5 Sensitivity analysis

Shadow price:

 Cutting time: Shadow price = 0

 Material: Shadow price = 0

 Firing: Shadow price = 103,092.7835

 Allowable range of Shadow price [ 96.6 ; 116 ]

 Glazing: Shadow price = 29,201,030.93

 Allowable range of Shadow price [ 36.207 ; 41.577 ] Sensitivity:

 1953448.28 ≤ Quantity large type need to produce ≤ 4720000

 25000 ≤ Quantity small type need to produce ≤ 10096296.3

 4.32989691 ≤ cutting hours used ≤ positive infinity

 8.4 ≤ firing hours used ≤ 116

 3.79310364 ≤ glazing hours used ≤ 41.57746497

 1047.42268≤ material used ≤ positive infinity

6 DuoCera sees small bricks selling well and doing well so they are trying to produce only small bricks So under what conditions should DuoCera produce ONLY SMALL Brick?

According to Sensitivity Report 1.6, only Glazing time has shadow price different from 0

So we change Right hand sight (Glazing time) to change Total profit

Conclusion: Allowable increase hours (Firing time) is: [ 10.889; 11 ]

 Firing time = [115.889; 116] so DuoCera should produce small bricks only

7 Because of some technical issues, the brick kiln had to be cut down by 3 hours/week – that is, only 37 hours a week instead of 40 hours like the original So has DuoCera's production plan changed?

Conclusion: If the hours for work are cutted down by 3 hours per week, DuoCera’s production

will be changed

CHAPTER 2: DECISION MAKING

1 In the initial case, which brick kiln should DuoCera use, and why?

Conclusion: Producing in Vinh Long ceramic is the best choice Because it brings maximum

profit

2 Should DuoCera take a survey if it's free? And if there is a fee, from how much does

it cost DuoCera won't accept surveys?

Case 1: Free survey

Conclusion: DuoCera company should do free survey.

Case 2: Paid survey

Profit difference between doing survey and not doing survey is:

X = 16,058,590,000 - 16,056,000,000 = 2,590,000 VND

Conclusion: If the fee for survey more than 2,590,000, they shouldn’t do survey If the fee less

than 2,590,000, they should do survey

CHAPTER 3: NETWORK DISTRIBUTION

DuoCera needs to transport goods to Ninh Thuan via the following routes, determine the appropriate route:

Conclusion: DuoCera should chose the route: Dong Nai – B – E – F – H – J – Ninh Thuan.
