Abstract [en]


Purpose: The aim of the work is to map the ergonomics in a production cell and propose and compare the solutions to identified problems. In order to identify the problem and come up with some solutions, these questions have been answered.• What factors lead to operations that are harmful to the body?• How can a production cell be designed to be more ergonomic for employees?• What are the advantages / disadvantages of ergonomics in a production company?


Method: To perform the study and achieve the purpose of the work, the authors used a case study company where observations were made in parallel with a literature review mainly on ergonomics variety of analysis and quality. The case study company has been used as the basis for the case study where ergonomics are mapped by means of observations, interviews and data that were analyzed by means of literature study done in parallel.

Study results: The study resulted in a survey of ergonomics in a production cell at the case study company and 5 different suggestions for improvement. The production cell on the case study company is a red cell today, which means that the production cell is in a non-accepted position and in need for urgent changes in ergonomics. Factors leading to bad ergonomics and a non-accepted position as Volvo's requirements have been identified. Many heavy lifting and many torque is what has the highest negative impact on the working environment and ergonomics. Lack of adequate lifting tools have led to those not used in the production cell today. This leads to repetitive work and encumbrance at the case study company. Further, also the working height of the paths contributed to an increased workload as operators are in an unnatural posture. All of these factors are the basis of the 5 suggestions for improvement as the study also resulted in. New custom lifting tools, job rotation, reverse the order of the court, new packaging and pallet to the gears and the robot turn. All these proposed solutions lead to reduced stress and improved ergonomics in the production cell as manual lifting and twists are reduced. The solutions also leads to the production cell shifting from a non-accepted position with demands of urgent change to a yellow production cell that requires an action plan for the future.


Implications: The aim of this study was to map the ergonomics in a production cell. With the study in hand, a conclusion is drawn that the aim has been achieved when all three of the questions have been addressed. Factors leading to poor ergonomics are identified. As well the advantages and disadvantages of investing in ergonomics identified and how production cells should be formed. With this information in mind, a number of proposed solutions have been developed.


Recommendations: Further studies on the subject are recommended to increase knowledge and interest. It may be appropriate to carry out more case studies at more industries to strengthen the study’s results and generalizability. Furthermore, studies are recommended where the entire work environment is studied and not only physical ergonomics. By studying the whole working environment and the many factors that interact it can lead to a greater force being created for higher efficiency and quality in production.
