Departamentalização matricial
Posted by Armando Brito Mendes | Filed under planeamento
Descrição do conceito de empresa matricial
A Departamentalização Matricial ou Organização Matricial, é um tipo híbrido de Departamentalização, no qual equipes compostas por pessoas de diversas especialidades, são reunidas com o objetivo de realizar tarefas com características temporárias. Ela evoluiu a partir da Departamentalização Funcional tradicional, aliada a dinamicidade das estruturas de projeto ou produto. Esse tipo de arranjo da organização, permite que se adote como ferramenta auxiliar de cálculos e computação elementos da Matemática conhecidos como “Teoria das Matrizes”

Five tips for building a work breakdown structure
Posted by Armando Brito Mendes | Filed under materiais para profissionais, planeamento
Conselhos sobre como dividir o projeto em atividades
1: Create a WBS dictionary for large projects
2: Use the summary activities as milestones
3: Break activities into two or more detailed activities
4: Make the final detailed activities action oriented
5: Don’t place requirements on the WBS

The Siena webpage

SIENA is a program for the statistical analysis of network data, with the focus on social networks.
Networks here are understood as entire (complete) networks, not as personal (egocentered) networks: it is assumed that a set of nodes (social actors) is given, and all ties (links) between these nodes are known – except perhaps for a moderate amount of missing data.
SIENA is designed for analyzing various types of data as dependent variables:
- Longitudinal network data:
- This refers to repeated measures of networks on a given node set (although it is allowed that there are some changes in the node set). Models can be specified with actor-oriented as well as tie-oriented dynamics.
- Longitudinal data of networks and behavior:
- This is like longitudinal network data, but in addition there are one or more changing nodal variables that are also treated as dependent variables, and referred to as behavior. The network will influence the dynamics of the behavior, and the behavior will influence the dynamics of the network. In other words, this is about the co-evolution of networks and behavior.
- Cross-sectional network data.
- ‘Cross-sectional’ means that only one observation is available. This method uses exponential random graph models (‘ERGMs’), also called p* models.
The ERG model is implemented in SIENA version 3, but not any more in version 4 (RSiena).
The name SIENA stands for Simulation Investigation for Empirical Network Analysis.

I teach two courses on programming in R. Slides etc for the (shared) lectures are here and extra resources for the M.Sc course are here.
My 1998 D.Phil. thesis, Neural Network Models for Breast Cancer Prognosis, is available for downloading in PDF (2.7mb) or 2-up PostScript (680kb).
S-PLUS survival analysis software (similar to that used in the thesis) is available for Unix and Windows. (Previous versions of the software are available for S-PLUS 3.4 and S-PLUS 2000.)
Slides from a seminar entitled Neural network based non-linear survival methods with applications to breast cancer prognosis are available for download as 4-up Postscript (zipped) (75kb)
Software for analysis of western medieval chant melodies, created in collaboration with the Oxchant Group in the Faculty of Music, is available here. A paper describing the work is available here.
A complete list of publications is available here.

Time Management Reminders
Posted by Armando Brito Mendes | Filed under Investigação Operacional, materiais para profissionais, planeamento
Begin with the end in mind.
First things first.
Don’t just list priorities; schedule them
Schedule only two or three “big rocks.”
Chunk tasks together, like with like.

Explicação para professores e alunos sobre IO
In a nutshell, operational research (O.R.) is the discipline of applying advanced analytical methods to help make better decisions.
By using techniques such as problem structuring methods (sometimes known as ‘Soft O.R.’) and mathematical modelling to analyse complex situations, operational research gives executives the power to make more effective decisions and build more productive systems based on:
- More complete data
- Consideration of all available options
- Careful predictions of outcomes and estimates of risk
- The latest decision tools and techniques

10 ways to avoid stupid project estimates
Posted by Armando Brito Mendes | Filed under planeamento
Bons conselhos no planeamento de um projeto
You can’t run a successful project with bad estimates, any more than you can build a solid house with faulty bricks and lumber. These simple steps will help you filter out the bad numbers you get today and improve the numbers you get tomorrow.
