WebAbstract: This paper considers the problem of minimizing the assembly time of multi-head surface mounting machines. The problem is decomposed into a hierarchy of related subproblems. Since all subproblems in the hierarchy are known to be of a combinatorial nature and computationally intractable, we develop heuristics which are based on … WebAbstract: This paper presents a framework for behavior modeling and scenario control based on hierarchical, concurrent state machines (HCSM). We present the structure and informal operational semantics of hierarchical, concurrent state machines. We describe the use of HCSM for scenario control in the Iowa Driving Simulator (IDS), a virtual …
