For the model limitation of classic job-shop scheduling, combined with actual production conditions, multi-resources-constrained scheduling optimization model with machine and mold constraints is established. According to this model, three-level optimization heuristic algorithm of parts level, resources level and optimization level is designed, and using an example to verify its feasibility and effectiveness. The result shows that the algorithm has a good optimizing performance and higher operation speed, with the ability to solve large-scale scheduling problems.

Organizing and managing lots of technical data which is needed in developing IETM(Interactive Electronic Technical Manual) is of great significance. In order to guarantee the platform-independent of technical data in IETM development and the data storage security, XML documents are used for describing data, while relational database is used for storing data. The mapping relation between XML documents and relational databases is established. And the algorithm about data transformation between XML documents and relational database are presented.

In the traditional design process of auto panels, the structure and functions of the panel are concerned more by designers, but the manufacturability is paid little attention to. Therefore, some problems appear during the manufacturing process. In this paper, a new approach, design for manufacturability using polychromatic sets, is introduced to evaluate the manufacturability of auto panels. And the systemic framework is established. Detailed explanations are given through an auto panel example. The evaluation process is described using polychromatic Sets.

In CITIS (Contractor Integrated Technical Information Service) collaborative manufacturing project, how the prime contractor reasonably chooses cooperativeenterprises and assigns tasks among them will directly effects on gaining benefit from the project. To solve this problem, in this paper, a new heuristic optimization algorithm is proposed for tasks assignment, which objectives are minimizing costs and reducing the number of enterprises selected based on theminimization of project time. Finally, the algorithm is varied through an example, and the evaluation for it is given.

In the study of job shop scheduling problem in mass injection molding processing enterprises, the practical job shop scheduling environment cannot be mirrored in the traditional study only considering machine resources. A dual-resource (machines and moulds) constrained job shop scheduling problem model was established in this paper, according to the actual factors of mass injection molding processing job shop scheduling. A heuristic active algorithm combined with priority rules is employed to give the solution. Finally, an example is made to illustrate the algorithm, whose schedule result is shown with a Gantt chart.
