Production scheduling is an important and complex problem faced by iron and steel enterprises, which is featured by its discrete and continuous process as well as multi-objective decision making characteristics. Recognized as a NP-Hard problem, it is clear that analytical method is difficult to effectively address this production scheduling problem. Combined with visual simulation technology, this...
The gating and riser system design plays an important role in the quality and cost of a metal casting. Due to the lack of fixed theoretical procedures to follow, the design process is carried out on a trial-and-error basis. The casting design optimization problem is characterized by multiple design variables, conflicting objectives and a complex search space, making it unsuitable for sensitivity based...
The gating and riser design plays an important role in the quality and cost of a metal casting. Due to the lack of existing theoretical procedures to follow, the design process is normally carried out on a trial-and-error basis. In this paper, the casting design is first formulated as a multi-objective optimization problem with conflicting objectives and a complex search space. An optimization method...
