When an automobile manufacturer develop a full designed car, it is necessary to also develop the engine which shall be mounted on the car. Therefore most of automobile manufacture builds its own factory for producing the engine. The major components of an engine are engine block (or cylinder block), cylinder head, crank shaft, connecting rod and cam shaft. Flow line is the typical concept of layout for machining these parts, especially for engine block. In order to design an engine block manufacturing line, several factors should be considered such as yearly production target, working hours, machines, tools, material handling equipments and so on. If the designers of manufacturing line were unaware of some factors those would be influenced on the system performance, it will make greater problems in the phase of mass production. Therefore the initial design of engine block machining line should be evaluated carefully. Simulation is the most powerful tool for analyzing the initial layout. This thesis introduce the major factors those should be considered for designing the machining line and their effects on the system performance. We also introduces the methods for developing input data for simulation, for example, interval of tool change for each machine. 3D simulation models are developed with QUEST. Using the simulation model developed the initial layout is analyzed, and we suggest some ideas for improvement.
