Sequential Tolerance Control in Discrete Parts Manufacturing

Abstract: The machining of complex parts typically involves a sequence of n operations on m machine tools. Conventional tolerance control specifies a fixed set point for each such operation and permissible variation about this set point to insure compliance with tolerance specifications. However, this approach may be inadequate for complex, low-volume, highvalue added parts. This paper introduc...

Sequential Competitive Facility Location Problem in a Discrete Planar Space

In this paper, there are two competitors in a planar market. The first competitor, called, the leader, opens new facilities. After that, the second competitor, the follower, reacts to the leader’s action and opens r new facilities. The leader and the follower have got some facilities in advance in this market. The optimal locations for leader and follower are chosen among predefined candida...

Two-machine group scheduling problems in discrete parts manufacturing with sequence-dependent setups

This paper focuses on minimizing the total completion time in two-machine group scheduling problems with sequence-dependent setups that are typically found in discrete parts manufacturing. As the problem is characterized as strongly NP-hard, three search algorithms based on tabu search are developed for solving industry-size scheduling problems. Four different lower bounding mechanisms are deve...

Motor Vehicle and Parts Manufacturing

Nature of the Industry The motor vehicle is an intricate series of systems, subsystems, and components assembled into a final product. Each manufactured part or component is integrated into the vehicle; none is developed to exist separately. Vehicles are constantly changing as new technology or reengineered components are incorporated, and as new and updated models are designed in response to c...
