Combined Design and Process Planning for Incremental Manufacturing

Design of a New Mathematical Model for Integrated Dynamic Cellular Manufacturing Systems and Production Planning

This paper presents a new mathematical model for integrated dynamic cellular manufacturing systems and production planning that minimizes machine purchasing, intra-cell material handling, cell reconfiguration and setup costs. The presented model forms the manufacturing cells and determines the quantity of machine and movements  during each period of time. This problem is NP-hard, so a meta-heur...

Generative System for Manufacturing Process Planning

Process Planning for Shape Deposition Manufacturing

Solid Freeform Fabrication (SFF) refers to a class of rapid manufacturing process that builds parts by incremental material deposition and fusion of thin 2-1/2 dimensional layers. Over this past decade, SFF has taken the manufacturing industry to new heights. However, parts produced by SFF processes exhibit a stair-step surface texture due to the presence of 2-1/2 dimensional layers and exhibit...

A Constraint Engine for Manufacturing Process Planning

We present a constraint-based model and planning engine for manufacturing process planning. By exploiting the expressive power of constraint programming (CP), all relevant, sometimes conflicting pieces of domain knowledge are represented. The planner applies standard propagation techniques and customized search to find cost-optimal solutions in presence of hard, soft and conditional constraints...

Semi-generative System for Manufacturing Process Planning

The generative method is a subject of theoretical and experimental research. Difficulties with its implementation are connected with the lack of formal description of the synthesis of activities constituting the manufacturing process. To overcome the difficulties while developing the huge technological knowledge base, a semigenerative method is often used. In this method the pattern is characte...
