answers of the problems

Q.1. Consider an unknown system with two inputs, x1, x2 , and one output, y, as shown in the following Figure 1a. Let inputs x1 be within the range X1 = [0,20] and x2 in X2 = [0,10]. Suppose that X1 has two associate membership functions, µS1(.) and µL1(.), describing “small” and “large,” respectively, and similarly X2 has µS2(.) and µ L2(.), as shown in Figure 2 (b)-(c). Now, suppose that we know, from experiments, the following input-output relations (fuzzy IF-THEN implication rules):

R1: IF x1 is small AND x2 is small THEN y = x1 + x2

R2: IFx1 is large THEN y = 1/2 x1

R3: IFx2 is large THEN y = 1/3 x2.

Otherwise, y = 0.

Let 0 x01 = 15 and x20 = 5 be given;

a) Calculate the fuzzy membership values of the outputs. (10-Marks)

b) Calculate the average value of the final output, corresponding to the input.(20-Marks)

c) Calculate the three membership functions, one “small” and two “large,” for the final output. (20-Marks)

Q.2. A manufacturing company produces 3 product types. The products are made of number of subassemblies and components. The bill-of materials (BOM) of these three products are depicted in the following figure. The numbers in the parentheses indicate the number of component needed for each unit of item to make one unit of upper level subassembly.

The company wants to plan the next 6 months period. The expected demands in the next six months are estimates as:

Product Type

A 300 250 400 150 350 475

B 200 300 250 600 550 375

C 500 350 450 550 300 650

Total 1000 900 1100 1300 1200 1500

The company employs 20 people. The number of workable days in next six months are as follows:

Months 1 2 3 4 5 6

Days 22 21 23 22 23 23

The company further uses overtime, subcontractor and part-time worker if necessary to meet the demand within the time period. However, if it is not possible to meet the demand within the period then the company uses backlog option.

The related company capacity is given below:

Regular time production : 2 unit/day/per worker

Overtime production : 1 unit/day/per worker

Subcontractor capacity : 75 units/per month

Part time worker capacity : 1 unit/day/per worker

The company does not use part-time worker in overtime period and does not use more than 10 working days for the overtime in a month.

The company sees a great benefit in reverse logistics and encourages its distributors and customers to return the products that have completed their economic lives, to the company. The previous experience show that the expected number of return items in next six periods would be:

Product Type P

1 E

2 R

3 I

4 O

5 D

A 30 50 40 30 25 50

B 40 40 30 20 25 50

C 20 25 30 50 25 20

Total 90 115 100 100 75 120

Yet again, the past experience indicate that the refurbishable/repairable/reusable product rate is on average 50% and the remaining 50% is disposed. However, the company realised that on average 20% of disposable products has some parts that are intact and with minor refurbishments these can be used in remanufacturing. These components belong to subassemblies A3, ß, and II.

Any full-time worker can refurbish/repair/reuse 4 units of returned products during normal working times and 2 returned products in overtime period if necessary. Further, 6 units of A1, or A2, or p, or I or Z subassembly components can be manufactured and assembled by a FT worker in a normal time if needed. These parts are not manufactured in overtime period. Neither subcontractor nor PT worker is used in component manufacturing separately.

The relevant cost figures are given below:

Costs

Output

Regular Time =$7 per unit

Overtime =$10 per unit

Subcontract =$15 per unit

Regular time cost of individual component production = $3/per unit

Inventory =$10 per unit per period on average inventory

Backorders =$20 per unit per period

Returned Items cost at regular time

Cost of recycling =$1/per unit

Disassembly & Repair cost =$2/ per unit

Maintenance cost =$1/ per unit

Disposal cost =$0.5/ per unit

Overtime cost of returned items

Disassembly & Repair cost =$2.5/ per unit

Maintenance cost =$1.5/ per unit

Prepare an Aggregate plan using different combinations of available capacity for this company for the next six months.

2. Quince Company has book income of $120,000 properly determined in accordance with financial accounting principles. The following information is also available: • The company received a $10,000 dividend from a large publicly-traded domestic corporation of which it owns less than 20%. • Income tax expense on the financial statements was $30,000. • Depreciation expense on the financial statements is $25,000 less than depreciation expense determined using tax laws. • The company received life insurance proceeds of $15,000. • Charitable contributions of $20,000 were made.

Determine the taxable income of Quince Company.
