Mapping Postural Severity of various manual tasks using P-SVR [Posture – State Variation Report] © method for Job Difficulty Evaluation

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 posture for operator comfort and to find out quantitative value of severity of work based upon postural video analysis. A compressor manufacturing process was studied for different activities like assembly, testing, material handling, inspection, disassembly and cleaning. These processes were evaluated for mapping severity of postures involved considering the elemental time and frequency. P-SVR method can be used as an extension of any method which is based on static observations of postures for analyzing the severity of work content and which is based upon either random or periodic photographic analysis. The scope of this paper is limited to highlighting these areas, where modifications in the processes can bring down the index of postural severity.In this paper we have compared three jobs being done in one industry in India on the basis of postural severity to guide the management in Industrial Dispute involving job evaluation.
