An Information System for the Cutting Stock Problem with Optimization of Retail Materials in Stock

Authors
Mendes, J; Fernandes, P; Pereira, CS;

Publication
2015 10TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI)

Abstract
Considering the new paradigm in the industry, where clients request small amounts of a growing range of products, the times of crisis and the fierce competition for businesses survival, it is crucial for Organizations to be able to reduce the waste of raw materials. In the manufacturing industry, the waste of materials could be minimized with the introduction of decision support systems in the process. In this paper we propose an information system that enables the optimization of purchases and consumption of materials, promoting waste reduction and boosting profitability.

Agile software project: proposal of a model to manage risks

Authors
Cunha, R; Pereira, CS; Pinto, JA;

Publication
PROCEEDINGS OF THE 2013 8TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI 2013)

Abstract
Risk is inherent in all software projects. To manage and control them represents gains for the development and success of projects. The risk management goal is to control, in a continue way, the risks that arise in all the phases of projects, and it's considered determinant to the projects' success. The risk management process is defined through models that specify the activities to accomplish during the project, with the aim to eliminate or minimize the impact of risks. Given the popularity of agile approaches, agile risk management has become central, because agile methodologies by themselves don't give an answer to the risks that might arise in a software project. The work presented in this article has a goal the definition of a risk management model, suited to agile development, in order to improve the existing risk management.

A decision support approach to automatic timetabling in higher education institutions

Authors
Fernandes, P; Pereira, CS; Barbosa, A;

Publication
JOURNAL OF SCHEDULING

Abstract
At a time when the need to reduce costs has become part of the day-to-day reality of all educational institutions, it is unthinkable to continue to manually perform those tasks (i.e., the creation of timetables) that can be automated and optimized. The automatic creation of timetables for educational institutions is one of the most studied problems by the scientific community. However, almost all studies have been based on very simplified models of reality that have no practical application. A realistic model of the problem, robust algorithms that are able to find valid solutions in highly restricted environments, and optimization methods that are able to quickly provide quality results are key factors to consider when attempting to solve this (real) problem faced by educational institutions. This paper presents a summary of the work performed by Bullet Solutions over the last few years, from the first stage of understanding and modelling the problem to the final analysis of the results obtained using the developed software under real conditions.

Building an informal ontology to support collaborative network operation: a case study

Authors
Carla Pereira; Cristovão Sousa; António Lucas Soares

Publication
Proceedings of PRO-VE'10 - 11th IFIP Working Conference on VIRTUAL ENTERPRISES, Saint-Etienne, France

Abstract
Regarding collaborative networks as social-technical systems, information and knowledge sharing implies sharing a set of common conceptual structures across organizations. Through this paper, we describe a case study on how to construct meaningful collective conceptualizations, by means of a new approach based on conceptual blending theory.
