Tujuan Strategi Tata Letak
Develop an economical layout which will meet the requirements of:– product design and volume (product strategy)– process equipment and capacity (process
strategy)– quality of work life (human resource strategy)– building and site constraints (location strategy)

Tipe – Tipe Tata Letak
• Fixed-position layout• Process-oriented layout
• Office layout• Retail layout
• Warehouse layout• Product-oriented layout

What is Facility Layout
• Location or arrangement of everything within & around buildings
• Objectives are to maximize– Customer satisfaction – Utilization of space, equipment, & people– Efficient flow of information, material, & people– Employee morale & safety
![Page 5: J0444 OPERATION MANAGEMENT](https://reader035.vdocuments.net/reader035/viewer/2022070420/56815e0d550346895dcc6a54/html5/thumbnails/5.jpg)
Desain Tata Letak harus Mempertimbangkan Objektivitas Berikut:
• Utilisasi ruang, peralatan dan orang yang lebih tinggi
• Aliran informasi yang lebih baik• Moral karyawan yang lebih baik• Interaksi dengan pelanggan yang
lebih baik• Fleksibelitas
![Page 6: J0444 OPERATION MANAGEMENT](https://reader035.vdocuments.net/reader035/viewer/2022070420/56815e0d550346895dcc6a54/html5/thumbnails/6.jpg)
Tipe – Tipe Tata Letak
• Fixed-position layout “Tata Letak dengan Posis Tetap”– Memenuhi persyaratan tata letak untuk proyek yang
besar dan memakan tempat seperti proyek pembuatan kapal
• Process-oriented layout “Tata Letak berorientasi Proyek”– Berhubungan dengan produksi dengan volume
rendah dan bervariasi tinggi• Office layout “Tata Letak Kantor”
– Menempatakan para karyawan, peralatan mereka dan ruangan / kantor yang melancarkan aliran informasi
![Page 7: J0444 OPERATION MANAGEMENT](https://reader035.vdocuments.net/reader035/viewer/2022070420/56815e0d550346895dcc6a54/html5/thumbnails/7.jpg)
• Retail/service layout “Tata Letak Ritel”– Menempatkan rak – rak dan memberi
tanggapan atas perilaku pelanggan• Warehouse layout “Tata Letak Gudang”
– Melihat kelebihan atau kekurangan antara ruangan dan sistem penanganan bahan
• Product-oriented layout “Tata Letak yang berorientasi pada Produk”– Mencari utilisasi karyawan dan mesin yang
paling baik dalam produksi yang kontinyu

Move material to the limited storage areas around the site
Manage varied material flow for each product
Locate workers requiring frequent contact close to each other
Expose customer to high-margin items
Balance low-cost storage with low-cost material handling
Equalize the task time at each workstation

Requirements of a Good Layout
an understanding of capacity and space requirements
selection of appropriate material handling equipment
decisions regarding environment and aesthetics
identification and understanding of the requirements for information flow
identification of the cost of moving between the various work areas

Fixed-Position Layout
• Design is for stationary project • Workers and equipment come to site• Complicating factors
– Limited space at site– Changing material needs
![Page 15: J0444 OPERATION MANAGEMENT](https://reader035.vdocuments.net/reader035/viewer/2022070420/56815e0d550346895dcc6a54/html5/thumbnails/15.jpg)
Office Layout
• Design positions people, equipment, & offices for maximum information flow
• Arranged by process or product– Example: Payroll dept. is by process
• Relationship chart used• Examples
– Insurance company– Software company

Retail/Service Layout
• Design maximizes product exposure to customers
• Decision variables– Store flow pattern– Allocation of (shelf) space to products
• Types– Grid design– Free-flow design

A Good Service Layout (Servicescape) Considers
• Ambient conditions - background characteristics such as lighting, sound, smell, and temperature.
• Spatial layout and functionality - which involve customer circulation path planning
• Signs, Symbols, and Artifacts - characteristics of building design that carry social significance

Product-Oriented Layout
• Facility organized around product• Design minimizes line imbalance
– Delay between work stations• Types: Fabrication line; assembly line
![Page 22: J0444 OPERATION MANAGEMENT](https://reader035.vdocuments.net/reader035/viewer/2022070420/56815e0d550346895dcc6a54/html5/thumbnails/22.jpg)
Product-Oriented Requirements
• Standardized product• High production volume• Stable production quantities• Uniform quality of raw materials &
components
![Page 23: J0444 OPERATION MANAGEMENT](https://reader035.vdocuments.net/reader035/viewer/2022070420/56815e0d550346895dcc6a54/html5/thumbnails/23.jpg)
Product-Oriented Layout Advantages
• Lower variable cost per unit• Lower material handling
costs• Lower work-in-process
inventories• Easier training &
supervision• Rapid throughput

Product-Oriented Layout Disadvantages
• Higher capital investment– Special equipment
• Any work stoppage stops whole process
• Lack of flexibility– Volume– Product
