Usability of cushions designed specifically for car industries’ assembly lines
author
Abstract:
Background: Ergonomics is a science that provides methods of creating reasonable adaption between occupation and worker by improving usability through consideration of job demands and human ability to satisfy them. A deep understanding of user’s thoughts on and attitudes toward utilizing a tool could improve its design. In the present study, two cushions designed particularly for one of car industries, assembly line were tested considering usability. Materials and Methods: From among the 50 employees of the assembly line, 44 employees were selected randomly to participate in the study. The research tool consisted of a researcher-made questionnaire containing 29 questions in 5 subscales (usefulness, efficiency, effectiveness, satisfaction, and safety). The validity of the questionnaire was estimated by a specialist (CVI = 0.85) and its reliability was calculated using Cronbach’s alpha (α = 0.87). Results: The mean scores of the 5 subscales of usefulness, efficiency, effectiveness, satisfaction, and safety were 6.5 ± 0.534, 6.5 ± 0.488, 5.3 ± 0.278, 6.4 ± 0.310, and 6.5 ± 0.534, respectively. Conclusions: Scores in all dimensions were above moderate and acceptable levels. Workers utilized them satisfactorily, and thus, producers can produce these cushions in large numbers without any problems. The performance of similar studies is recommended in designing other tools and instruments and the application of ergonomic principles in their design.

This paper deals with the modeling of production processes in automotive industries by models based on partial differential equations.The basic idea consists on the derivation of kinetic equations to model production flow on an assembly line. Numerical results based on data of an assembly plant are presented. The work implements a recent discussion [34, 38] for general flow on unstructured netw...
