Developing root locus stability diagrams using a personal computer
… Suppliers are trimming time from design and production schedules wherever possible in order to compete in the world market. It is for these, and other reasons that computer aided stability analysis is so important. The object is to ensure a safe and stable system and yet minimize the time …

Pre-Consumer Food Waste at Three Dining Facilities
… to assess the amount (weight) of pre-consumer (production) food waste at a large university, serving 18,000 meal plan holders, and identify major contributors of food waste (i.e. food categories, types of waste). Dining facility managers and waste coordinators (WCs) were voluntarily recruited …

An Analysis of Labor Turnover in a Georgia Paper Company
… training competent workers and disruptions in schedules which are caused by inadequate labor supplies. Disruptions in production schedules appear when a manager finds that he is short-handed because of labor turnovers. Disruptions in scheduling, cost industry money and this unnecessary cost can …

An algorithm to determine the causes of inventory stock-outs in manufacturing firms
… shorter cycle times, and more closely integrated production schedules have led to an extremely low tolerance for inventory stock-outs. In such an environment, any shortage is costly, and understanding why stock-outs occur and how to prevent them is an important issue. However, the answer to the …

High Velocity Supply Chain: Redesigning a Long Lead Time, Short Shelf Life Supply Chain
… stockout events every year adversely impact production schedules. This project addresses these problems by imagining inventory as a control loop problem, where we take the system from its current form as an "open" loop and convert it to a self-correcting "closed" loop. We do this by first …

Comparison of Scheduling Algorithms for a Multi-Product Batch-Chemical Plant with a Generalized Serial Network
… methodologies developed for batch-chemical production are seldom applied in industry (Musier & Evans 1989 and Grossmann et al. 1992). Scheduling decisions may have significant impact on overall company profitability by defining how capital is utilized, the operating costs required, and the …
