Professor and HOD, Dept. of Biotechnology, SSBT’s C.O.E.T., Jalgaon (MS) Abstract The effects of control factors (parameters) were determined by experimental study by using Taguchi Fractional factorial design of deburring process of Mat manufacturing process. The optimum process parameters were determined based on their influence on the output of women workers. This study involves six factors viz. BMI, Popliteal height, Buttock-knee length, Seat base height, Seat back rest height and Room temperature were investigated in this study. The response/dependent variable is workers efficiency in terms of output. Taguchi’s technique was used for experimentation. Taguchi L27 orthogonal array (OA) was applied to evaluate the effect of theses parameters’ and signal-to-noise data used for compute the importance and their effect on the response parameter. The analysis of variance (ANOVA) has been used to evaluate a most favorable result of the parameters. The results showed that the seat base height was the most significant parameter followed by BMI and the least influence was room temperature in winter season. Experimental results are provided to confirm the effectiveness of this approach. Keywords: Ergonomic, Productivity, Taguchi method, orthogonal Array, SN ratio, ANOVA I. INTRODUCTION Ergonomics is concerned with making the workplace more efficient, comfortable and safe. Effective application of ergonomic in work system design can achieve a balance between worker and task demands. This can improve workers efficiency, as well as comfort and job satisfaction. Many research studies have shown positive effects of applying ergonomic principles in a workplace design, machine design and tool design [1-3]. In small scale industries the workstations are designed in a random manner. They are giving little important to the workstation design and workers life [3]. The physical dimensions in the design of an industrial workstation are of major impertinence from the point of view of production efficiency and operators physical and mental comfort. Small changes in workstation can have a considerable impact on worker productivity and as well as industrial health and safety. Insufficient posture from an important designed workstation cause a static muscle efforts. It is directly effect on performance and productivity. The Taguchi technique is powerful, superior experimental design tool. It is simple, efficient and systematic approach to optimize designs for performance, quality and cost. Taguchi approach to design of experiment in easy to adopt and apply for users with limited knowledge of statistics [4]. In addition, through incurring minimum experimental coast, this approach improved the quality characteristics rapidly and efficiently by reducing the effect of source of variation. In the rapidly changing situation “human” is the most important and valuable resource to play very important role in every organization. A many studies have been carried out from time to time to examine the changes in the productivity. Studies have also been carried out to analyze productivity tendencies in major manufacturing industries [5]. When any one work in sitting on a hard surface without back rest or lumber support, the ischial tuberosity (inferior protuberances of the pelvic bones) is active, around which the pelvic strap rotates due to weight of upper body. This is the main reason to develop musculoskeletal disorders (MSDs) in women workers in the industry. It has been reported in ergonomics that squatting posture is very tiresome [6-7]. Ergonomics studies in industrial workers are many, but the specific study on the women working has not been carried so far. In the present study, Taguchi method of experimental design was applied to establish relationships between BMI, Popliteal height, Buttock-knee length, Seat base height, Seat back rest height, room temperature and workers output. In this proposed method, statistical approach based on Taguchi and Analysis of variance (ANOVA) technique had been adopted for obtaining the influence of each parameters. II. OBJECTIVES OF THE STUDY The primary objective of this research is to take the collection of existing situations of working method and to assess the industrial productivity in the changing industrial condition of the industrial units of Jalgaon MIDC, India. Where the task of deburring (finishing) is performed in a sitting position on hard floor with folding legs at knee, in which worker is cutting the extra lengths tubes with Blades. It is repetitive and continuous for 8 hours (except lunch break) in working period. In this condition, back and neck is bend excessively and
