The Barrett Textile Mill was checked by inspectors enforcing Occupational Safety and Health
Administration (OSHA) codes. The inspectors found violations in four categories: hazardous
materials, fire protection, hand-powered tools, and machine guarding. In each category the mill was
not in 100% compliance. Each percentage point of increase in the compliance level in each category
will reduce the frequency of accidents, decrease the accident cost per worker, and constitute
progress toward satisfying the OSHA compliance level. However, achieving compliance does cost
the mill money. The following table shows the benefits (in accident frequency and accident cost per
worker) and the costs of a percentage point increase in compliance in each category:
Accident Frequency Reduction
(accidents/105 hr. of exposure)
Accident
Cost/Worker
Reduction
Cost/Percentage Point
Compliance
1. Hazardous
materials
0.18
$1.21
$135
2. Fire
protection
0.11
0.48
87
3. Handpowered tools
0.17
0.54
58
4. Machine
guarding
0.21
1.04
160
Category
To achieve 100% compliance in all four categories, the mill would have to increase compliance in
hazardous materials by 60 percentage points (i.e., it is now at 40% compliance), in fire protection
by 28 percentage points, in hand-powered tools by 35 percentage points, and in machine guarding
by 17 percentage points. However, the management of the mill faces a dilemma, in that only
$52,000 is available to spend on safety. Any larger expenditure could jeopardize the financial
standing of the mill. Thus, management hopes to achieve a level of accident reduction and
compliance that is within the company's budget limitation and that will satisfy OSHA authorities
enough to temporarily delay punitive action. Therefore, management has established four goals,
listed here in order of importance:
1. Do not exceed the budget constraint of $52,000.
2. Achieve the percentage increases in compliance necessary to achieve 100% compliance in
each category.
3. Achieve total accident frequency reduction of 20 accidents/105 hours of exposure. (This
goal denotes management's desire to minimize the frequency of accidents even if 100%
compliance cannot be achieved in all categories.)
4. Reduce the total accident cost per worker by $115.
Berdasarkan kasus di atas, maka jawablah pertanyaan di bawah ini
a. Tentukan entity, input dan output system.
b. Identifikasi stakeholder dan problem owner dalam sistem tersebut sesuai dengan
permasalahan di atas serta jelaskan fungsinya.
c. Identifikasi tujuan akhir dari sistem untuk permasalahn di atas.
d. Buatlah influence diagram untuk permasalahan di atas.
e. Buatlah model dengan menggunakan program Analytica untuk permasalahan di atas.
f. Buatlah model matematika untuk permasalahan di atas.
Petunjuk pengerjaan Ujian Akhir Semester
1. Jawaban UAS harus diketik serta dijilid rapi.
2. Jawaban harus urut sesuai dengan urutan di atas.
3. Gambar influence diagram diperbolehkan menggunakan kertas di atas ukuran A4 serta
diperbolehkan dikerjakan dengan gambar tangan asalkan gambar tersebut jelas.
4. Gambar model dengan Analytica harus disertakan beserta hasil pengujiannya. Hasil
diperbolehkan dalam bentuk print screen dari hasil model Analytica.
5. Program Analytica untuk model sesuai dengan permasalahan harus dikirimkan ke e-mail :
[email protected] dengan format nama UAS_Kelompok#.
6. Laporan/jawaban dalam bentuk hardcopy harus dikumpulkan paling lambat hari Senin tgl
22 Desember 2014 pk. 15.00 serta menandatangani daftar hadir UAS. Pengumpulan
terlambat dianggap tidak mengikuti UAS.
7. Model dalam bentuk program Analytica harus dikirim paling lambat hari Selasa, 23
Desember 2014 pk. 23.59. Pengumpulan terlambat dianggap tidak mengikuti UAS
8. Apabila terdapat hal-hal yang kurang jelas dapat langsung bertanya pada dosen pengampu.
9. Selamat mengerjakan.
