Oturarak çalışanlar için
literatürdeki çalışmalar, sırt/boyun ağrısı ile ilişkilendirilen fiziksel iş
yükü, aydınlatma, sıcaklık konforu gibi çevresel faktörler ve iş organizasyonu
ile ilgili konularla ilişkilendirilmektedir. Ofis yerleşim probleminde
mobilyaların konumu doğrudan ya da dolaylı olarak çalışanların performansını
etkileyebilmektedir fakat bilindiği kadarıyla bu konu yeterince ele
alınmamıştır. Bu yüzden, bu çalışmada fraktal yerleşim konseptinin hücre tipi
ofis yerleşimine nasıl uyarlanacağı temsil edilmiştir. Çalışma, temelde eşit
olmayan alanlı tesis yerleşimi için geliştirilen matematiksel modelin, ergonomi
gereksinimlerini de karşılayacak şekilde yeniden tanımladığı için özgündür..
Önerilen yaklaşım, bir üniversitenin bölümlerinde bulunan ofis yerleşim
problemi için uygulanmıştır. Ofis çalışanları tarafından tanımlanan yakınlık
ilişkileri ve yeniden düzenlenen kısıtlar sonucu elde edilen yerleşimin mevcut
yerleşimden daha iyi olduğu sonucuna ulaşılmıştır

Anahtar Kelimeler

ofis ergonomisi, hücresel yerleşim, karma tamsayılı programlama, fraktal yerleşim

FRACTAL OFFICE LAYOUTS CONSIDERING ERGONOMICS

Öz

A number
of studies in literature focus on seated workers and investigate physical
workload, related back/neck pain, environmental ergonomics such as
illumination, thermal comfort, cooperation, and work organization. Although,
the positioning of furniture and related units may directly or indirectly
influence the performance of workers, up-to best knowledge, the office layout
problem is not studied in detail. Therefore, this study aims to illustrate how
fractal layout concept can be adapted for cell type office layouts. The study
is novel because, the constraints of a basic mathematical model that is
originally defined for unequal area facility layout problem is redefined as to
meet the ergonomic requirements and generate a layout. Proposed approach is used
to solve the office layout problem in a university department. It is concluded
that the layout obtained by considering the closeness ratings defined by office
employees along with the redefined constraints outperforms the current layout.
