This thesis addresses the challenge of optimizing the inventory layout within the Cleanroom environment at IQM, a company specializing in quantum chip production. The objective of this study was to propose an improved layout to enhance the efficiency of their chip production process.
The study was based on a mixed methods Applied Action Research (AAR) approach. The research involved several key stages. First, a Current State Analysis (CSA) was carried out to thoroughly understand the existing inventory layout, material flow, and associated inefficiencies. This involved observations, discussions with Cleanroom users and the Material Specialist, and an analysis of the current layout's strengths and weaknesses. Key findings of the CSA revealed inefficiencies, delays, potential for cross-contamination, and poor space utilization due to the unstructured storage system.
Subsequently, a literature review explored the best practices in inventory layout design, particularly within Cleanroom environments, drawing upon Lean manufacturing principles and the 5S methodology. This informed the development of a tailored proposal for an improved inventory layout, incorporating solutions such as a structured storage system with clear labeling, segregated storage using desiccator cabinets, and a waste sorting procedure. The proposed layout was then validated through a pilot run and stakeholder feedback, leading to further refinement.
The outcome of this study is a validated, improved inventory layout design. Its implementation is expected to benefit IQM by streamlining the production process, increasing efficiency, reducing downtime and errors, minimizing cross-contamination risks, and improving product quality.
