Vocationalism Varies (a Lot)

Vocationalism in the University

It is an uncommon event when a University President overtly discusses fundamental educational policies. Usually, the administrative officer of a great university must spend his time on a multitude of practical matters which leave little time for the consideration of the main job of the University, even though the inclination might be present. The recent lectures of Robert Maynard Hutchins, Pres...

Simultaneous Lot Sizing and Scheduling in a Flexible Flow Line

This paper breaks new ground by modelling lot sizing and scheduling in a flexible flow line (FFL) simultaneously instead of separately. This problem, called the ‘General Lot sizing and Scheduling Problem in a Flexible Flow Line’ (GLSP-FFL), optimizes the lot sizing and scheduling of multiple products at multiple stages, each stage having multiple machines in parallel. The objective is to satisf...

A Lot of Data

This article encourages the use of explicit methods in linguistics by attempting to estimate the size of a linguistic data set. Such estimations are difficult because redundant data can easily pad the data set. To address this, I offer some explicit operationalizations of the data and their features. For linguistic data, negative associations do not indicate true redundancy, and yet for many me...

Lot-sizing on a tree

For the problem of lot-sizing on a tree with constant capacities, or stochastic lot-sizing with a scenario tree, we present various reformulations based on mixing sets. We also show how earlier results for uncapacitated problems involving (Q,SQ) inequalities can be simplified and extended. Finally some limited computational results are presented.
