Application of P-SVR Methodology for comparison of Postural Severity of various tasks on compressor assembly line

Abstract

The scope of this paper is to describe the newly defined Posture – State Variation Report (P-SVR) Method of postural analysis to highlight the areas for improvement in work processes for operator comfort and to find out quantitative value of severity of work based upon postural video analysis. In a compressor manufacturing unit, different processes were studied for different activities like assembly, testing, material handling, inspection, disassembly, cleaning, etc. These processes were evaluated for the severity of work postures involved considering the elemental time and frequency of various postural severities. For reducing work severity, using P-SVR analysis, we can find out the work elements with highest postural severity and the longest duration. The scope of this paper is limited to highlighting the work elements where modifications in the processes can bring down the P-SVR index value leading to work simplification.
