A priori reformulations for joint rolling-horizon scheduling of materials processing and lot-sizing problem

In many production processes, a key material is prepared and then transformed into different final products. The lot sizing decisions concern not only the production of final products, but also that of material preparation in order to take account of their sequence-dependent setup costs and times. The amount of research in recent years indicates the relevance of this problem in various industrial settings. In this paper, facility location reformulation and strengthening constraints are newly applied to a previous lot-sizing model in order to improve solution quality and computing time. Three alternative metaheuristics are used to fix the setup variables, resulting in much improved performance over previous research, especially regarding the use of the metaheuristics for larger instances. © 2013 Elsevier Ltd.

Evaluation of the performance of pharmacists in terms of providing health assistance at a university hospital

OBJETIVE: This study aimed to assess the practices of pharmacists in Hospital Care. Method - we interviewed 20 pharmacists from the Pharmacy Division by applying a structured instrument, in September 2005. This instrument addressed aspects related to the main activities at the Hospital Pharmacy, which were assessed according to indicators organized into five areas: sector management, hospital pharmacotechniques, committee activities, information and pharmacotherapeutic follow-up, as well as teaching and research activities.RESULTS: the Pharmacy Division considered all structural aspects under analysis as essential for the good development and application of its services. We found that some essential services, such as the Medication Information Service and Pharmacotherapeutic Follow-up, were absent. Pharmacist professionals were dissatisfied about human resource and physical structure dimensioning, and they presented as not very active in terms of Pharmaceutical Care.CONCLUSION: Results indicate that care is still centered on the drug, with few clinical activities. We suggest reformulations in service management, particularly in the management of pharmacists.

Reformulation of variational inequalities on a simplex and compactification of complementarity problems

Many variational inequality problems (VIPs) can be reduced, by a compactification procedure, to a VIP on the canonical simplex. Reformulations of this problem are studied, including smooth reformulations with simple constraints and unconstrained reformulations based on the penalized Fischer-Burmeister function. It is proved that bounded level set results hold for these reformulations under quite general assumptions on the operator. Therefore, it can be guaranteed that minimization algorithms generate bounded sequences and, under monotonicity conditions, these algorithms necessarily nd solutions of the original problem. Some numerical experiments are presented.

Formulações fortes para o problema de dimensionamento de lotes com várias plantas

This paper considers the multi-plant lot sizing problem. Each item can be produced in any plant and it is possible to meet the demand of a particular plant with production from one (or several) other plants, in this case, incurs a transfer cost. The objective is todevelop strong formulations for this problem. Reformulations that based on the shortest path problem and facility location problem are investigated. Finally, some computational results are presented comparing all the proposed formulations.

Procedimentos para descrição de figuras em texto impresso visando à acessibilidade para pessoas cegas: um estudo a partir de um livro de educação física adaptada

This study was aimed to analyze a procedure that makes the description of pictures in printed text from a book that promotes accessibility for blind people. In addition, the study was aimed to analyze the reformulations suggested by the judges and the index of agreement between researcher and judges. The descriptions were submitted to judges to evaluate the content of the material. The results were obtained through the analysis of two assessments: 1) agreement rate ‒ between the researcher and judges A and B, and between judge A and judge B and 2) analysis of the suggested reformulation. In quantitative terms, the results indicated that the material described achieved a high reliability. In qualitative terms, the reliability achieved represents the quality of the material offered, with well structured descriptions where writing meaning is equivalent to image information, fulfilling the purpose to present in printed text the elements represented in the pictures, effectively conveying their meaning.

As decisões de investimento e a instabilidade financeira

Initially, the text handles the theories of ancient classical and changes with the emerging of the debates of the schools of economic of Keynes and Kalecki. Over the years, from 1930 onwards, investment theories were debated and modified by various schools of economic thought. One of the debates that stands out in this work are the theories of Minsky that will bring new reformulations to Keynesian theory and a greater focus on psychological factors as determinants of investment decisions. Through financial instability hypothesis Minsky explains how the decisions to invest and the access to credit cause instability to financial system. Finally the work will show how access to credit is material when companies decide to invest and how these investments are often handled due to information asymmetries in the market. The financial institutions seek to maximize their profits while dribbling moral hazard and adverse selection, and thus the government needs to intervene once in a while as a regulator to maintain the solvency of the system

A importância da experimentação no ensino de química e ciências

The profile of students has changed a lot, mainly due to the advent of new technologies, which in attractiveness has attracted the attention of students, and becoming a difficulty the teacher to attract the attention of the student to class. In this sense, it is needed reformulations in pedagogical practice so that the student's attention turns to science, arousing their curiosity. Thus, in Chemistry and Science Teaching, and lectures must encourage discussions about science, and one of the possible ways to insert dynamic classes is by inserting the trial. Thus, this present course conclusion work aims at presenting and discussing the ways in which Experimentation in Chemistry and Science Teaching has been applied in classrooms, the difficulties of its implementation as a teaching methodology, as well as the advantages and disadvantages of their use depending on the type of approach, training teachers, among other factors
