This document discusses the analysis of automated flow lines, including lines without storage buffers, with storage buffers, double stage lines, and multistage lines. Storage buffers are temporary storage areas between workstations that allow a line to continue operating if one portion breaks down. Reasons for using storage buffers include reducing the effect of breakdowns, smoothing cycle time variations, and storing parts between stages with different production rates. The document outlines the approaches for analyzing lines without buffers and the benefits of using buffers to divide lines into stages.

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
