Study on ES Based Generation System Planning

Based on the analysis of expert experience on generation system planning(GPS), the theory of knowledge based method is introduced into GPS to express the constraints of engineering(viz. Expert experience of engineering), and to discard abundant improper program during the earlier stage of GPS. In this situation, the difficulty degree of optimizing calculation in the later stage of GPS is lessened. And then, integrating expert system with production simulation in a method of GPS is proposed and is verified with an example. The results show that the method presented is effective.

Study on Approach to Optimize Network Planning Schedule for Fixed Resources Constraint

Network planning schedule optimization is one of the pivotal issues in engineering project management. The current studies on schedule optimization aim at achieving the optimal goals by least additional resources. In this paper, from transferring the critical path, the authors suggest a schedule optimization algorithm through transferring partial resource of un-critical activities to the critical activities. The result of applying the model shows that it is helpful for resolving schedule optimization issue for fixed resources.     

A Study on the Job-shop Scheduling Problem

This paper discusses a new approach of job shop production scheduling with the time limit of starting and completing work.In this approach,all operations in the queue are sorted according to their values of remaining operating time,and a preliminary feasible solution of production scheduling is achieved,which makes a shortest circulation time of parts in the system.Then adjustment is made aiming at maximum ahead/behind time span of operation block.The process is iterated until a satisfactory scheduling solution is obtained.Through analysis and application proof,the scheduling algorithm is suitable and feasible in engineering projects.     

Production Planning Method for Steelmaking-continuous Casting Process Based on Time Backward and Process Simulation

Reasonable production planning effectively ensures smooth operation. According to the analysis of the characteristics of steelmaking-continuous casting production process, a production planning method for steelmaking - continuous casting process based on time backward inference method and process simulation is presented. Production plan meeting certain criteria is rapidly gained by time backward inference method, and is regarded as input of simulation model in steelmaking process. Considering time randomicity in production process and transporting equipment restriction, production plan meeting more restrictive conditions, such as no equipment conflict, continuous casting, and etc, is acquired through simulating. It assures that the plan is carried out in practice. The instance demonstrates the feasibility of the method.     

Relations between Urban Design and City Planning in the Work of Plan-making

In this paper, three fundamental principles of city planning under the present system are brought forward: the integration of urban design and city planning, the double attributes and position of the urban design and the correspondence between the urban design and the city planning in levels.
