Abstract
In this work, a systematic methodology to construct distributed layouts has been
developed. Previous researches in this field suggest distributed layouts as an alternative to
process layouts. But there has been no systematic methodology so far to develop distributed
layouts. Earlier works concentrate on evaluating different production schedules for randomly
distributed resources throughout the plant floor. As opposed to former approaches, in this work,
distributed layouts are developed based on actual production and routing data. Taking into
account the exact capacity requirements of machines, a methodical approach to distribute
resources rather than random assignment is considered. The need for developing process layouts
is analyzed and justified using product similarity and cell utilization. Process layouts are
developed only when the given production data meets process layout requirements. The
efficiency of proposed approach relative to traditional process layout strategy has been evaluated
in terms of material handling cost for both single and multi period settings.
In a multi period setting, the impact of demand disturbances on both process and
distributed layouts is studied using case studies. From the case study results, it is concluded that
distributed layouts constructed using proposed approach performs exceedingly well over
traditional process layout approach. Distributed layouts proved to be efficient and robust for
both single and multi-period cases. Even huge fluctuations in demand level of products had only
little impact on distributed layouts whereas process layouts suffered tremendous loss in terms of material handling cost. It turned out that for all cases, the improvement in efficiency of distributed layouts was more than 30% over process layouts.
