This paper describes an application of a Constructive Genetic Algorithm (CGA) to the Minimization Open Stack Problem (MOSP). The MOSP happens in a production system scenario, and consists of determining a sequence of cut patterns that minimizes the maximum number of opened stacks during the cutting process. The CGA has a number of new features compared to a traditional genetic algorithm, as a p...

The development, design and selection of subsea petroleum production equipment and facilities are critical activities, as the decisions made will impact the success and profitability of the project. Technical, economic and government regulations are some of the factors that need to be evaluated in order to contract subsea services and procurement activities. Pre-studies need to be conducted to ...

Manufacturing system design and operation is critical to achieve strategic company objectives. This must aim fitting manufacturing systems capabilities to the different demand market environments, having in consideration the different approaches and strategies that should be used. In this paper we develop a framework for characterizing production system conceptual models and linking them to bot...

Authoring learning content is an area under pressure due to conflicting requirements. Adaptive, templatebased, highly interactive, multimedia-rich content is desired for current learning environments. At the same time, authors need a system supporting collaboration, easy re-purposing, and continuous updates with a lower adoption barrier to keep the production process simple, specially for high ...

This paper presents a knowledge based approach to consonant recognition. In traditional knowledge based systems, the expert is the linguist/phonetician who attempts to describe and quantify the acoustic events, in the form of production rules into phonetic description. This paper proposes to alter the expert's role so that the expert only needs to provide the basic structure of the phonetic cla...

Good nutrition in animal production systems is essential to economically produce a healthy, high quality product. In fish farming, nutrition is critical because feed represents 40-50% of the production costs. Fish nutrition has advanced dramatically in recent years with the development of new, balanced commercial diets that promote optimal fish growth and health. The development of new species-...

In this paper we consider a make-to-stock production system whose permanent production capacity can be increased temporarily by making use of some contingent resources, while this capacity acquisition has a constant lead time associated with it. We present a model where the capacity management problem is handled in an integrated manner with the inventory management, under non-stationary and sto...

On the global scale, extensive pastoral production accounts for 10% of total meat production (or a billion head of camels, cattle and small animals on all continents)1 and supports some 200 million pastoral households. Yet, despite the considerable benefits conferred by pastoral production systems, they are often denigrated as being archaic. [R1] On the African continent, despite these subjecti...

Email is emerging as an important channel for ISP customer care, and manual processing is labor intensive. A new system for automating the processing of large volumes of email received by an ISP customer care center is described. The system automatically determines the embedded email structure, extracts key email fields needed for aggregation and ticketing, performs keyword analysis, and invoke...

Research has demonstrated that deception is more cognitively demanding than truthful communication. Furthermore, evidence suggests when put under certain cognitive constraints interlocutors exhibit more disfluencies during production planning. One common emotion regulation strategy involving deception is emotion suppression. Recent research indicated emotion suppression can lead to maladaptive ...
