Optimization of design efficiency by implementing Design for Excellence : A Case Study for Optimizing Rottne Industri AB:s current harvester cabin production

Sammanfattning: The effects of humanity's actions on the environment have been a viral topic for many years. The efficiency of refining raw materials is crucial in reducing these effects. This thesis was thereby tasked with improving the assembly efficiency of Rottne Industri AB:s harvester cabin. Various theories were utilized to improve the design, with Design for Excellence being the most notable. By implementing a seven-step product development process, concepts could be generated and later scored based on the customer's comments and discovered issues. The authors selected the idea with the highest score and developed it until they achieved a concept meeting the product's objectives. The concept was then validated by performing simulations and calculations related to its assembly efficiency, environmental impact, and cost. The redesign resulted in an idea possessing a design efficiency 135% higher than the original, a 72% shorter assembly time, 13% less weight, a 25% reduction in greenhouse gas emissions, and a 41% reduction in assembly and material costs.
