SYSTEMS ENGINEERING AND SOFT SYSTEMS METHODOLOGY : A REVIEW

Öz

Bu makalede Sistem Mühendisliği konusunda en son gelişmelerden birisi olan ‘Soft Systems Methodology SSM ’ konusu kısaca incelenmektedir. Öncelikle, SSM’ in oluşumunu hazırlayan koşullar Sistem Mühendisliğinin kısa bir tarihçesi içinde sunulmaktadır. Burada ‘‘Hard’Systems Engineering’’ yaklaşımının kolaylıkla formule edilemeyen sosyo-ekonomik problemlerin çözümündeki yetersizlikleri özet­lenmektedir. Daha sonra, sosyo-ekonomik problemlerin çözümünde SSM’ in niye daha başarılı olabileceği tartışılmakta ve SSM Metodolojisi ana hatlanyla anlatıl­maktadır

SYSTEMS ENGINEERING AND SOFT SYSTEMS METHODOLOGY : A REVIEW

Öz

In this paper, Soft Systems Methodology SSM , quite a recent development in Systems Engineering, is reviewed briefly. First, a historical background on Systems Engineering that led to the emergence of this area is provided. Here, the limitations of 'Hard' Systems Engineering in dealing with ill-structured socio-economic problems are summarised, and the reasons for SSM becoming a relatively more 'successful' approach are given. The paper is concluded by a review of the SSM Methodology.

Anahtar Kelimeler

• Systems Engineering, ‘Hard’Systems Engineering, System Analysis and Design, Soft Systems Methodology, Socio-Economic Systems
