In theory, because factors that affect industrial development is too complex or related material is too difficult to obtain, so we can make short-term forecasts just rely on previous data though decomposing trend, periodicity and noise factors.

factors promote urbanization in the suburbs, setting off another tide of urban expansion, it provides the impetus for the secondary cities to across the "threshold rule"; Construction of transport corridor--Traction power:Construction of transportation corridor and the industry belt are often the stretch axis of the main city and the secondary cities' spatial extension, and it has a point to the role to urban space expansion; speed of transport increased has injected new vitality for urban development, and it has provided favorable conditions to accelerate the pace of urban expansion; Needs of people living--Invisible Power:With the rapid economic development, urban living conditions gradually improved, "magnetic" elements[13] brought relocation of residents, has brought a corresponding relocation of the relevant departments within the city, and drives the outward expansion of urban space; Polarization and the diffusion effect--Basic power: Unifying adjacent cities speeds up population, material

This analyzing method helps us to figure out the dynamic change process and the cross influence in our electric power supply and demand system, in order to make optimal control scheme and implement effective control. 1.2 The definition of the study object With the enhancement of people's consciousness on environmental protection, cleaning environment brings more and more health benefits than material benefits that economic development brings [8-10].

Meanwhile, compared with Rigid-Plastic FEM, Rigid-ViscoPlastic FEM considers the influence of deformation velocity on the material flow stress in constitutive equation, which can reflect the true plastic deformation process of materials [1-4].
DEFORM software provides different methods to define the materials flow stress [7]: 1) Power law, 2) Tabular data format, 3) Flow stress for aluminum alloys (Type 1), 4) Flow stress for aluminum alloys (Type 2), 5) Linear hardening, and 6) User defined flow stress routine.
It shall be noted that when the simulation conditions of materials exceeds the bounds of the strain, strain rate or temperature defined in the tabular data, the program will extrapolate based on the last two data points which may lead to loss of accuracy.

The pessimistic estimate, takes into account potential risks such as lack of materials, downtime, failure, etc.
It is also important that staff is aware that any mistake or loss of Kanban cards can endanger the continuity of material flow and supply of materials to the customer.

Hence, there are still difficulties to be solved in applying MQL to the cutting of difficult-to-machine materials, which cause severe tool damages resulting in short tool service life due to their material properties of high strength, low thermal conductivity, high affinity to cutting tools, high strain hardening, etc [4].
It also suggests that the increase in cutting temperature to some extent is necessary to cause the thermal softening of the workpiece of heat resistant materials in the shear zone and at the tool tip.
