Fig. 1 Load distribution of Shield Tunnel Segment 2.2 Material Model and Main Parameters Shield tunnel lining is usually precast in factory and assembled in the shield tail.
In designing segments, ignoring the weakening effect of the joints leads to the overestimation of design axial force, and thus causes unnecessary cost due to extra reinforcement and material.

The static structure of FMS is described with UML, but for the dynamic characteristics of the system we complete with object-oriented petri nets, and then the system Petri net model was transform into the UML state diagrams and sequence diagrams according to the corresponding mapping and the transformation rule, thus we obtain a integrity model of the system while improving the reliability of the model. 1 Introduction Flexible Manufacturing System (FMS) is an automated manufacturing systems consisting of a unit controller, material transport and storage systems and a number of CNC machining equipment.

The design, material, size, weight and the way of locating in the vehicle space make serious difficulties for automotive manufacturers.
Another example is Mercedes S-class which reduced 50 kg from entire of vehicle weight by using POF replacing copper [8].According to classical mechanic science, which reducing the amount of weight is directly proportional to fuel consumption and this magnitude is approachable by comparing power-to-weight ratio in different vehicle models.

Summary After the late 20th century, especially in the 21st century, with the development of the knowledge economy, the number of service goods provided and consumption began to rise sharply, establishing cost pricing based on material cost, due to neglect market factors, in theoretically lack researching on service goods pricing more in-depth, gradually expose the defect of lacking practical guidance, affect in-depth development of new markets, make service enterprises face difficulty of shrinking market; The competition-oriented pricing strategy is that enterprises adjust their prices based on competitors' pricing, or widen differences with competitors through technological innovation, but because of replicability and non-patent factors in mobile communication service model, make the advantages of technological innovation difficult maintain for long, so it is possible to make enterprises fall into the negative competition by reducing price.
