Pesquisa operacional

Em 'Pesquisa operacional', 8o edição, Hamdy A. Taha apresenta um texto extremamente claro e didático, capaz de abranger com equilíbrio a teoria, as aplicações e os cálculos de pesquisa operacional e, ao mesmo tempo, dar ênfase aos conceitos matemáticos complexos, minuciosamente explicados por meio de exemplos numéricos que eliminam a necessidade de provas matemáticas formais. Essa característica da obra é comprovada pelas aplicações práticas de software, as quais permitem aos estudantes a assimilação de conceitos que não poderiam ser fixados com eficiência de outro modo, e pelos inúmeros casos práticos e cerca de mil problemas que, presentes no livro todo, servem para ilustrar a teoria apresentada.

Operations Research

An Introduction

"For junior/senior undergraduate and first-year graduate courses in Operations Research in departments of Industrial Engineering, Business Administration, Statistics, Computer Science, and Mathematics." "Operations Research" provides a broad focus on algorithmic and practical implementation of Operations Research (OR) techniques, using theory, applications, and computations to teach students OR basics. The book can be used conveniently in a survey course that encompasses all the major tools of operations research, or in two separate courses on deterministic and probabilistic decision-making. With the Tenth Edition, the author preserves classical algorithms by providing essential hand computational algorithms as an important part of OR history. Based on input and submissions from OR students, professors, and practitioners, the author also includes scenarios that show how classical algorithms can be beneficial in practice. These entries are included as "Aha! Moments" with each dealing with stories, anecdotes, and issues in OR theory, applications, computations, and teaching methodology that can advance the understanding of fundamental OR concepts. The Companion Website for "Operations Research, " 10/e (www.pearsonhighered.com/taha) provides valuable resources for both students and instructors. Resources include case studies that require students to employ OR tools from multiple chapters, Excel, TORA, and AMPL files as well as additional chapters and appendixes. A note about accessing the Companion Website: Instructors should click the Register link and follow the on-screen directions to access the site. Instructors need a Pearson Education account to register, but do not require an additional Access Code. Students can access the Companion Website by redeeming the Access Code included in the front of their new copy of "Operations Research, " 10/e. Students can also purchase Companion Website access online. The Instructor Resource Center contains the Solutions Manual and PowerPoints of the art from the book. Instructors can download these resources from www.pearsonhighered.com/irc"

Action Research

The Advantages and Limitations of Practice in Responding to Poor People's Voices Through Microfinance

This case study highlights the importance and limitations of practice on participatory action research. Action research is concerned with action and learning as core themes. In participatory action research, the research community brings in their expertise and participates with the researcher to bring about new knowing while aiming to achieve change. The practitioner researcher has the advantage of basing their research vision on the practice they aim to research on and drawing from those experiences. At the same time, they need to be able to lay aside their value judgments, honed by practice, in order to allow other voices to inform the research. The challenge is maintaining the balance between drawing from those resources and separating themselves from what they know in order to objectively collect and analyze research data. This case study uses data from my 2016 PhD thesis to discuss the research journey with a rural community in Zimbabwe and an urban community in Zambia within the context of providing microfinance loans. The research focus was to listen, learn, and allow the voices of poor people to inform a new approach to lending money for livelihoods support. However, the research lenses were tinted by my experiences as a microfinance practitioner, and this affected and almost deviated the research trajectory. As I recovered from this setback and concluded my research, I learnt the reality of carrying value judgments into the research. This was inevitable, and I needed to have internalized ways of checking the influence of those judgments on the research. Most importantly I learnt the value of taking in all that comes through the research process as outcomes that warrant consideration. I also learnt the value of frequent reference to the methodology protocols as designed at the outset, and consciously accommodate adaptations informed by emerging data.
