A survey of multi-project environment on complex product manufacturing enterprises found that most concurrent project schedules can't be implemented well together, and duration delay became a common phenomenon because of various coordinate reasons. Based on grey correlation analysis(GCA), the paper presented an evaluation method for coordinate level of concurrent project schedules, which provided...
Aviation project which always involves too many resources need to do resource leveling for enhancing the utilization of resources so as to reducing project cost. Intelligent optimization algorithms and heuristic approaches are inefficient and inflexible when solving large-scale aviation resource leveling problems. A hybrid algorithm based on Artificial Immune Algorithm (AIA) and Ant Colony Optimization...
Based on critical chain theory, a new method for aircraft development project was proposed on assembly task scheduling, which can effectively improve flexibility of assembly scheduling scheme. In the method, the priority rules for critical chain identification was established by the three characteristic parameters, and then the algorithm steps which identifies critical chain was listed by project...
Because of long investment cycle, large investment and many uncertainty factors, water project has the characters of irreversibility and postponability. So the investment value of water project is a dynamic one due to these uncertainties. The traditional investment value evaluation model ignores the impact of the above factors, thus can not evaluate the strategic value arising from the risk of water...
This paper proposed a method of integrated progress control on aviation manufacturing projects. By analyzing the background of aviation manufacturing, the model of integrated progress control was presented, in which the indexes of the duration, cost and quality are integrated into scheduling plan. Based on the model, regarding Manufacturing Bill of Materials (M-BOM) as fundamental data source, the...
Water project has the characters of long investment cycle, muti-objectiveness, uncertain and so on. The traditional investment decision-making model usually only makes decision from the perspective of engineering and technical, while ignoring the impact of the above factors. The interactive idea can modify the decision-making results according to uncertain conditions during the course of decision-making,...
