Besides spatial elements, their spatial configuration is an important factor affecting urban image. In practice of urban planning, good designers do thoroughly consider goals of urban design and constraints of urban planning. In this paper taking the layout problems of a residential zone as background, a framework of procedural modeling and a constrained layout optimization approach is presente...

Circuit design in deep sub-micron technologies requires that designers deal with numerous data, constraints, analysis, synthesis, and optimization tools. Although synthesis tools are widely used at Intel, new circuit technologies are evolving and are often not well supported by existing synthesis tools. Deep sub-micron technology requires that the impact of physical design be considered early i...

one of the most important issues in the plant layout design especially in mass production organizations with high inter-plant logistics is‘material flow and inter-plant traffic analysis and its effects on the production capabilities or pauses in production lines. in this paper the inter-plant traffic analysis issue on the basis of single channel queue model (m/m/1) is analyzed in a carmaker c...

A steel hot rolling mill subjects steel slabs to high temperatures and pressures in order to form steel coils. We describe the scheduling problem for a steel hot rolling mill. We detail the operation of a commercial decision support system which provides semi-automatic schedules, comparing its operation with existing, manual planning procedures. This commercial system is currently in use in sev...

Path planning is one of the most vital elements of mobile robotics, providing the agent with a collision-free route through the workspace. The global path plan can be calculated with a variety of informed search algorithms, most notably the A* search method, guaranteed to deliver a complete and optimal solution that minimizes the path cost. D* is widely used for its dynamic replanning capabilit...

Today’s product demand and mix changes requiring reconfiguration of cells in each period of a multi-period planning horizon, This paper proposes a mixed-integer non-linear programming model for reconfigurable CMS design to meet changes in product mix & demand in each period of a multi-period planning horizon. The proposed model, to the best of author’s knowledge, is the most comprehensive model...

Electro-thermal co-design of power modules is required to maximize the capabilities promising semiconductor devices. The chip layout on substrate, which restricted by size module determines electrical and thermal characteristics module. This paper proposes a optimization strategy for based multiobjective electro-thermal design algorithm. parasitic inductance resistance SiC are evaluated using u...
