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.
Analysis of automated flow lines
- 1. ABHILASH P ANALYSIS OF AUTOMATED FLOW LINES
- 2. CONTENTS Analysis of transfer lines 1. without storage buffer 2. with storage buffer 3. Double stage 4. Multistage 2
- 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
