Quoting Customer Lead Times

Lead and Lead Poisoning from Antiquity to Modern Times

Lead, because of its low melting point, was one of the first metals used by man. It was probably isolated soon after the ancients discovered the use of fire. Archeological discoveries indicate the presence of lead objects and pigments during the early Bronze Age. In ancient Egyptian and Greco-Roman times metallic lead was produced as a by-product of silver mining. Extensive evidence of ancient ...

Exploration of Opportunities to Reduce Lead Times

Exploration of Opportunities to Reduce Lead Times for Engineered-To-Order Products by Jan Alarik Elfving Doctor of Philosophy in Engineering-Civil and Environmental Engineering University of California, Berkeley Professor Iris D. Tommelein, Chair Scholars and practitioners have long advocated the benefits of reduced lead times. Moreover, most, if not all members of a supply chain would gain fro...

Material Requirement Planning under Fuzzy Lead Times

This paper proposes a fuzzy multi-objective integer linear programming approach to model a material requirement planning (MRP) problem with fuzzy lead times. We incorporate to the crisp MRP model the possibility of occurrence of each one of the possible lead times. Then, an objective function that maximizes the possibility of occurrence of the lead times is considered. By combining this objecti...

Optimal ordering policies with convertible lead times

A firm receives orders that will be required at an uncertain time given by an Erlang distribution, and over time observes the associated independent exponential events. The firm, in turn, places orders at a linear cost from a supplier with fixed lead time l and has the option of converting (expediting) each order, at a cost, over a certain time interval after the order is originally placed. A c...
