3. BUFFER STORAGE
 It is just a temporary storage connected between
the two or more workstation
 When a breakdown occurs on an automated flow
line, the purpose of the buffer storage zone is to
allow a portion of the line to continue operating
while the remaining portion is stopped and under
repair

4. REASONS FOR USING STORAGE BUFFERS
 To reduce effect of station breakdowns
 To smooth cycle time variations
 To store parts between stages with different
production rates

5. AUTOMATED FLOW LINES WITHOUT
STORAGE BUFFER
 In this type we consider the analysis of continuous
flow line without storage capacity.
 when flow line breakdown there are two approaches
*upper-bound approach work part is not removed
from the station when a breakdown occurs at that
station
* lower-bound approach the work part is taken out of
the station

6. AUTOMATED FLOW LINES WITH STORAGE
BUFFER
 In this one or more storage buffers link between
workstations along the flow line
 One of the methods by which flow lines can be
made to operate more efficiently
 The buffer zones divide the line into stages. If
one storage buffer is used, the line is divided into
two stages

7. ANALYSIS OF A TWO STAGE TRANSFER
LINE
 The two stage line is divided by a storage buffer
of capacity is expressed in terms of the number of
work parts that it can store.
 The buffer receives the output of stage 1 &
forwards it to stage 2, temporarily storing any
parts not immediately needed by stage 2.
 The ideal cycle time Tc is the same for both
stages

8. ANALYSIS OF A MULTI STAGE TRANSFER
LINE
 If the line efficiency of an automated production
line can be increased by dividing it into two
stages with a storage buffer between, then one
might infer that further improvements in
performance can be achieved by adding
additional storage buffers
