Like many large manufacturing companies, Rohm and Haas is caught between giant raw material suppliers and powerful retailers at opposite ends of the supply chain. In the early 1990’s, several new competitors entered the emulsions market, posing a direct threat to the company’s larges business unit, Polymers and Resins (P&R). In addition, P&R was faced with the increasing price pressure from cus...

This paper presented a mixed integer programming for integrated scheduling and process planning. The presented process plan included some orders with precedence relations similar to Multiple Traveling Salesman Problem (MTSP), which was categorized as an NP-hard problem. These types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...

In a reverberant environment, sounds reach the ears through several paths. Although the direct sound is followed by multiple reflections, which would be audible in isolation, the first-arriving wavefront dominates many aspects of perception. The "precedence effect" refers to a group of phenomena that are thought to be involved in resolving competition for perception and localization between a d...

Efficient generation of assembly plans has significant implications on manufacturing costs, however, the underlying mathematical problem is both theoretically and computationally intractable. In the previous paper (Part I), we developed a graph-theoretic framework for the general problem, and we described a constraint satisfaction construct that generates correct assembly precedence graphs give...
