Towards a taxonomy of process quality characteristics for assessment

Previous assessment of process quality have focused on process capability (i.e. the ability of a process to meet its stated goals). This paper proposes a taxonomy of alternative process quality characteristics based on intrinsic and extrinsic quality attributes. The ultimate goal of this taxonomy is to provide a framework to conduct process assessments using different process quality aspects. Such a framework would considerably broaden process quality perspectives beyond the primary measure of process capability. It would also allow practitioners to identify and evaluate relevant quality characteristics for processes based on specific contexts and implications. For the process assessment model developers, it offers a list of process quality characteristics that could be used to develop relevant process measurement frameworks

Applying an adaptation of the Prado Project Management Maturity Model in an academic context

Dissertação de mestrado integrado em Engenharia e Gestão de Sistemas de InformaçãoThe organization’s strategy of a company is determinant in its performance. Failing strategies compromise the achievement of its goals. Thus, the interest in the field of project management has been increasing and has generated several tools used by companies. The need to develop methodologies to evaluate the performance of projects in organizations has a strong contribution to the development of maturity models. Maturity models help organizations to define their organizational strategy. The lack of knowledge of these maturity models causes organizations to experience problems in the development and improvement of their project management processes. In this dissertation, it was developed an analysis of the most relevant models of project management maturity by comparing them. The main objective of this dissertation is to adapt and apply a maturity model to assess the evolution of the maturity of project management practices in development teams in the academic environment. Afterward the theoretical study of the different maturity models, it was applied the Prado Project Management Maturity Model. This simplified model assesses the performance and maturity to development teams in the IT area. The model is applied to the project teams of curricular subjects of Development of Computer Applications of the second academic year and Information Systems and Technologies Project of the fourth academic year of the Integrated Masters in Engineering and Management of Information Systems course at the University of Minho. To achieve this goal, the methodology used was the Case Study because its purpose is to gather information about the real context that allows a greater and more detailed knowledge about the topic. The Case Study was developed through questionnaires answered by the project managers of the different teams. Through the application of the model, it was possible to compare the maturity between the two curricular units and to verify the effectiveness of the learning methods and strategies, and results in project management competencies throughout the course. Observing that there is a significant evolution in maturity from the Information Systems and Technologies Project teams compared to Development of Computer Application teams.A estratégia organizacional de uma empresa é determinante no seu desempenho. Estratégias que falham põem em causa o alcance dos seus objetivos. Desta forma, o interesse na área de gestão de projetos tem vindo a aumentar e tem gerado várias ferramentas que podem ser utilizadas pelas empresas. A necessidade de metodologias de avaliação do desemprenho de projetos nas organizações contribui para o desenvolvimento de modelos de maturidade. Os modelos de maturidade auxiliam as empresas a definir a sua estratégia organizacional. A falta de conhecimento destes modelos de maturidade faz com que as organizações tenham problemas no desenvolvimento e melhoria dos seus processos de gestão de projetos. No presente trabalho foram analisados os mais relevantes modelos de maturidade de gestão de projetos, através da comparação dos mesmos. O principal objetivo desta dissertação consiste na adaptação e aplicação de um modelo de maturidade para avaliar a evolução da maturidade das práticas de gestão de projetos em equipas de desenvolvimento em ambiente académico. Após a análise teórica dos diferentes modelos de maturidade, aplicou-se o Modelo de Maturidade em Gestão de Projetos de Prado. Este modelo simplificado restringe a avaliação do desempenho e maturidade a equipas de desenvolvimento na área das TI. Este modelo foi aplicado nas equipas de projeto das unidades curriculares de Desenvolvimento de Aplicações Informáticas do segundo ano letivo e Projeto de Tecnologias e Sistemas de Informação do quarto ano letivo do curso Mestrado Integrado em Engenharia e Gestão de Sistemas de Informação da Universidade do Minho. Para concretizar o objetivo proposto, a metodologia utilizada foi o Estudo de Caso pois o seu propósito é a junção de informação sobre um contexto real que permite um maior e mais detalhado conhecimento sobre o mesmo. O Estudo de Caso foi desenvolvido através de questionários respondidos pelos gestores de projetos das diversas equipas. Através da aplicação do modelo, foi possível comparar a maturidade entre as equipas das duas unidades curriculares e verificar a eficácia dos métodos e estratégias de ensino em competências de gestão de projetos ao longo do curso. Observando-se, assim, que existe uma evolução significativa da maturidade de gestão de projetos das equipas de Projeto de Tecnologias de Sistemas de Informação em relação às equipas de Desenvolvimento de Aplicações Informáticas

Climate Change and COP26: Are Digital Technologies and Information Management Part of the Problem or the Solution? An Editorial Reflection and Call to Action

The UN COP26 2021 conference on climate change offers the chance for world leaders to take action and make urgent and meaningful commitments to reducing emissions and limit global temperatures to 1.5 °C above pre-industrial levels by 2050. Whilst the political aspects and subsequent ramifications of these fundamental and critical decisions cannot be underestimated, there exists a technical perspective where digital and IS technology has a role to play in the monitoring of potential solutions, but also an integral element of climate change solutions. We explore these aspects in this editorial article, offering a comprehensive opinion based insight to a multitude of diverse viewpoints that look at the many challenges through a technology lens. It is widely recognized that technology in all its forms, is an important and integral element of the solution, but industry and wider society also view technology as being part of the problem. Increasingly, researchers are referencing the importance of responsible digitalization to eliminate the significant levels of e-waste. The reality is that technology is an integral component of the global efforts to get to net zero, however, its adoption requires pragmatic tradeoffs as we transition from current behaviors to a more climate friendly society

A framework development to predict remaining useful life of a gas turbine mechanical component

Power-by-the-hour is a performance based offering for delivering outstanding service to operators of civil aviation aircraft. Operators need to guarantee to minimise downtime, reduce service cost and ensure value for money which requires an innovative advanced technology for predictive maintenance. Predictability, availability and reliability of the engine offers better service for operators, and the need to estimate the expected component failure prior to failure occurrence requires a proactive approach to predict the remaining useful life of components within an assembly. This research offers a framework for component remaining useful life prediction using assembly level data. The thesis presents a critical analysis on literature identifying the Weibull method, statistical technique and data-driven methodology relating to remaining useful life prediction, which are used in this research. The AS-IS practice captures relevant information based on the investigation conducted in the aerospace industry. The analysis of maintenance cycles relates to the examination of high-level events for engine availability, whereby more communications with industry showcase a through-life performance timeline visualisation. Overhaul sequence and activities are presented to gain insights of the timeline visualisation. The thesis covers the framework development and application to gas turbine single stage assembly, repair and replacement of components in single stage assembly, and multiple stage assembly. The framework is demonstrated in aerospace engines and power generation engines. The framework developed enables and supports domain experts to quickly respond to, and prepare for maintenance and on-time delivery of spare parts. The results of the framework show the probability of failure based on a pair of error values using the corresponding Scale and Shape parameters. The probability of failure is transformed into the remaining useful life depicting a typical Weibull distribution. The resulting Weibull curves developed with three scenarios of the case shows there are components renewals, therefore, the remaining useful life of the components are established. The framework is validated and verified through a case study with three scenarios and also through expert judgement

Towards a Conceptual Design of an Intelligent Material Transport Based on Machine Learning and Axiomatic Design Theory

Reliable and efficient material transport is one of the basic requirements that affect productivity in sheet metal industry. This paper presents a methodology for conceptual design of intelligent material transport using mobile robot, based on axiomatic design theory, graph theory and artificial intelligence. Developed control algorithm was implemented and tested on the mobile robot system Khepera II within the laboratory model of manufacturing environment. Matlab© software package was used for manufacturing process simulation, implementation of search algorithms and neural network training. Experimental results clearly show that intelligent mobile robot can learn and predict optimal material transport flows thanks to the use of artificial neural networks. Achieved positioning error of mobile robot indicates that conceptual design approach can be used for material transport and handling tasks in intelligent manufacturing systems

Friction Force Microscopy of Deep Drawing Made Surfaces

Aim of this paper is to contribute to micro-tribology understanding and friction in micro-scale interpretation in case of metal beverage production, particularly the deep drawing process of cans. In order to bridging the gap between engineering and trial-and-error principles, an experimental AFM-based micro-tribological approach is adopted. For that purpose, the can’s surfaces are imaged with atomic force microscopy (AFM) and the frictional force signal is measured with frictional force microscopy (FFM). In both techniques, the sample surface is scanned with a stylus attached to a cantilever. Vertical motion of the cantilever is recorded in AFM and horizontal motion is recorded in FFM. The presented work evaluates friction over a micro-scale on various samples gathered from cylindrical, bottom and round parts of cans, made of same the material but with different deep drawing process parameters. The main idea is to link the experimental observation with the manufacturing process. Results presented here can advance the knowledge in order to comprehend the tribological phenomena at the contact scales, too small for conventional tribology
