ABSTRACT

Pedal sewing operation is a man-machine system. This operation takes place at a workstation usually known as single-person-owned premises meant for stitching clothes of the clients of the shop owner. The data collected comprises 30 sewing machine operators working on standalone pedal-driven sewing machines. The field study indicated that there is a considerable Musculoskeletal disorder on the part of the operator. Based on this data, mathematical co-relationships are established between various causes and effects of this activity. The chapter reports on: (i) planning of collection of data; (ii) execution towards collection of data; (iii) presentation of collected data; (iv) processing of the data for formulation of cause-effect relationships. Upon formulation of model, the reliability of model and its optimization is executed. The collection of data was done on 40 causes/input parameters/ independent variables and 1 effects/output parameters/dependent variables. The causes are clubbed and converted into five independent dimensionless terms known as pi terms such as Π11 Π21 Π31 Π41 Π5. The effects/output/ dependent parameter is nomenclated as Z1.
