Basing on isotropic material and taking the relative density of materials as design variable, SIMP approach with high efficiency is easy to be realized by program.
In other words, the iterating results under the control of local rule will ultimately determine the distribution of materials in the design domain.
(2) The distribution of solid materials in design domain through iterative process is controlled by the local rule.

In this research, a new Thermal Insulating Concrete Block (TICB) is produced via "sandwich" structure by spent polystyrene foam, cement and other raw materials.
Fig.4 Temperature change inside test rooms made by different wall materials (a) group 1 (b) group 2 Conclusions Developed TICB in this research satisfies the requirements of new wall material such as apparent density, compression strength, and thermal insulating property etc al.
Briefly, its comprehensive performance is superior to other wall materials'.

Introduction The Material Requirements Planning (MRP) basic calculation computes a future projection of the inventory level − on a time horizon at least equal to the total upstream lead-time − by algebraically summing the stock at hand, the planned receipts and the gross requirements coming from the Master Production Schedule (MPS): if, for a certain item, the projected inventory level gets below a predefined threshold (which can eventually include safety stocks), a new procurement or production order is released.

The thermal process of welding mainly depends on the distribution form of external heat source, the thermal and physical properties of materials, heat transfer with the surrounding environment.
This method is also applicable to other materials, high-temperature thermal processing of numerical simulation theory.
