The possibility of increasing productivity and improving business processes using methods and tools of industrial engineering and systems implementation of lean manufacturing
KOTTOVÁ, Jitka
This diploma thesis concerns the possibility of increasing productivity and improving business processes using methods and tools of industrial engineering and systems implementation of lean manufacturing in the company Schwan-STABILO ČR, s.r.o. The concept of lean production is known from the 50 of the last century and was first applied to the Japanese automaker Toyota, which due to its production system (Toyota Production System) was able to produce faster, cheaper and above all to a higher standard than its Western competitors. The main objective of this thesis is an analysis of the current state of the process and drafting of the required state of the process so that waste can be eliminated and productivity increased. With the implementation of lean methods and tools of production has been achieved the following improvements: - reduce the number of operators from the current 9 to shift to 5 operators in the shift, - increase the overall efficiency of facilities by more than 10 %, - reduction of machines from an average of 83 minutes to 22 minutes, - reducing the continuous production period of 59 days (74,14 days that for 15 days), - decreasing of the stock material, semi finished products and finished products from 404 790 pieces to 82 350 pieces.

Analysis of aplication potential of the Lean manufacturing principles in the selected industrial company
ŘÍHA, Karel
The basis of lean manufacturing is to minimize the inventories to reveal the disfunctions of the production system and to optimize process to avoid every kind of wastes. Lean systems are characteristic with smooth pull production system with one piece flow and just in time supplements of inventories. The layout of the line is transformed to the U work cell and the material is ordered by using kanban tickets. To receive the potential of implementation of the lean manufacturing principles we can use indicators IE - industrial efficiency and PLT - pruduction lead time.

Usage of lean manufacrturing in costs management
Hobzová, Veronika ; Šoljaková, Libuše (advisor) ; Halíř, Zbyněk (referee)
Lean manufacturing is the method to drive the costs down. Thesis concerns historic development of lean manufacturing methods giving special attention to Taylor's scientific management, husbands Gilbreth motion studies and Ford's production schema for "T" model. From today praxis the thesis is considering TPS (Toyota Production System) developed by Toyota Motor Corporation as an application of lean manufacturing. It was further developed by James Womack and Daniel Jones in their lean manufacturing theory analysis. The thesis introduces the example about fictitious HAD Corporation that is constructed on the bases of three real IT global companies. Analysis applies Womack's and Jones theory of lean manufacturing including five steps: value, value stream, flow, pull, perfection. The thesis can serve as an overview of lean manufacturing history, current methods and case study.
