Optimization of substrate handling

Abstract: The client is an organization founded and is operational in Sweden, Stockholm. The company focuses on manufacturing of clean tech solutions with its self-developed technology. Their technology generate power from renewable sources. The technology is applied to a substrate which is manufactured inside the factory, today's handling of the substrate must be made more effective. The purpose of the work is to analyze and optimize the handling of substrate in the factory. This includes from substrate manufacturing to storage to the next process in the chain.  The approach to the work began with a background study, preparation of a schedule, development of concepts and concept evaluation. To structure the work, the decision was made to follow the methods developed in the book Six Sigma’s.  The background study gathered information and knowledge about the subject to give a more profound understanding. Market studies were also conducted to find suitable solutions as well as components and products.  Several concepts were developed using brainstorming. The concepts were evaluated intuitively and using Pugh's matrix. The most suitable concept was further developed and dimensioned based on the conditions. Computer models were manufactured for the development and illustration of concepts.  The project resulted in the way the company transfer rolls today is the most optimal with the conditions that exist. The focus was therefore shifted to the development of a paternoster plant for storing rolls. The storage system that was developed holds up to 10 rolls at a time with a weight of 450 kg each. The construction has a maximum height of 3,17 meters, width of 3 meters and a depth of 1,6 meters. The concept will increase the efficiency of the workers by making it easier to sort rolls and reduce the workload.  There are several possibilities for improvement for optimizing the substrate handling in the factory and these are discussed in the last chapter.
