Abstract [en]

In today’s society companies facing increasingly challenges, competition and customer demands are constantly increasing. This has led to the traditional production approach no longer being sustainable. A philosophy that has been developed to meet these new types of manufacturing requirements is Toyotas Lean Manufacturing. Lean manufacturing was only meant for the car industry at first but has now been adopted by all types of manufacturing even in the public sector such as hospitals. 

The purpose with this report is to increase the profitability in manufacturing of compressor bladethrough Lean philosophy and methods. Using Lean methods to identify unnecessary cost in the process means no big investment is required to increase profitability. 

The goal of the report is to first identify problem areas in today’s manufacturing process and then come up with improvement suggestions enabling the company to lower their cost. 

The work was done with an empirical data collection of qualitative and quantitative data through Interviews, observations, measurements and data analysis. The largest amount of data comes from primary data collected during the project. Secondary data such as inventory values ​​and manufacturing data were taken from the company database.

Mapping of the current state shows that only a small part of the actual lead time is value-increasing time for the product and the time the customer is willing to pay for. Several problems and Muda were identified in the manufacturing process that causes non-value-increasing time. Based on the analyses, the most serious problem was defined as overproduction. The solution to overproduction was a Kanban system with Supermarket inventory.

With the introduction of this new production and inventory planning system, the return on bonded capital in the internal stock would increase by approximate 127%. By releasing the bound capital, an investment for purchase of machine parts that reduces the set-time can be made.
