management as a part of product lifecycle management

Tässä työssä käsitellään maailmanlaajuisen paperi- ja sellutehtaille laitteita toimittavan yrityksen Andritz:in dokumenttien hallintaa, keskittyen lähinnä yrityksen service- liiketoiminnan ja tuotteen elinkaaren hallinnan tarpeisiin. Tarkoituksena on selvittää kuinka aikaisemmin yritykselle muihin tarkoituksiin valittu dokumenttien hallinta-järjestelmä sopii Service-liiketoiminnan tarpeisiin. Työ perustuu kirjallisuutteen sekä tekijän työn ohella sekä haastatteluin keräämään näkemykseen liiketoiminnasta tällä alalla. Työssä käsitellään yleisellä tasolla dokumenttien hallintajärjestelmiä, niiden rakennetta ja perusominaisuuksia, sekä esitellään markkinoilla olevia erityylisiä ratkaisuja. Työssä esitellään myös Andritz:in dokumenttien hallinnan nykytilaa, tuotteen elinkaaren päävaiheet, dokumenttien hallinnan merkitys niissä ja nykyisin käytössä oleva dokumenttien hallintajärjestelmä. Näiden rinnalla pyritään tuomaan esille Service- liiketoiminnan erityispiirteet ja tarpeet dokumenttien hallinnalle niiden kannalta. Työhön on sisällytetty myös käytännön esimerkki dokumenttien hallinnasta suuressa käynnissä olevassa projektissa. Projektissa käytetään dokumenttihotelli palvelua dokumenttien projektin aikaiseen hallintaan. Hotellissa olevat dokumentit tulee siirtää myös Andritzin omaan järjestelmään, tämä siirto on tehty osana työtä.

The Design of a Software Lifecycle Management Framework to a Configuration Management System

Keeping track of software assets and managing software installations in IT environments can be a hard endeavor, especially when the size and diversity of the environment grows. How to install and uninstall software efficiently and cost effectively? Are there too few or too many software licenses purchased? If installed, is the software actually in use? Software Asset Management (SAM) is a process that involves managing and optimizing the purchase, deployment, maintenance, utilization, and disposal of software applications within an organization. This master’s thesis describes a special Software Lifecycle Management Framework to provide solutions to the multitude of challenges within SAM. The main objectives when designing the framework was to provide a set of tools to control the software assets during their entire lifecycle while trying to minimize the costs related to owning and managing them.

MODELING A COMPUTER APPLICATION FOR MANAGEMENT OF MAINTENANCE ACTIVITIES OF UNPAVED ROADS

ABSTRACTThis study presents a contribution to the modeling of a computer application employing a method of serviceability performance for unpaved roads, aiming the management of maintenance/restoration activities of the primary surface layer. The proposed methodology consisted of field inspections during dry (April to September) and rainy (October to March) periods, during which objective evaluations were performed to survey of defects and their densities and degrees of severity. To aid the functional classification of analyzed road sections and the determination of the defect with major influence on the serviceability of these roads, the method of serviceability performance proposed by Silva (2009)was implemented in the Visual Basic for Applications (VBA) language in Microsoft Excel software. With the use of the computer application proposed it was possible to identify among the defects analyzed in field, through the index of serviceability of the sampling unit per defect type (ISUdef), which one had the greatest influence on determining the relative serviceability index per road section (IST). The results allow us to conclude that the computer application Road achieved satisfactory results, since the objective evaluation criteria applied to road sections denotes consistency regarding their serviceability.

Project Management Tools in Agile Embedded Systems Development

Agile methods have become increasingly popular in the field of software engineering. While agile methods are now generally considered applicable to software projects of many different kinds, they have not been widely adopted in embedded systems development. This is partly due to the natural constraints that are present in embedded systems development (e.g. hardware–software interdependencies) that challenge the utilization of agile values, principles and practices. The research in agile embedded systems development has been very limited, and this thesis tackles an even less researched theme related to it: the suitability of different project management tools in agile embedded systems development. The thesis covers the basic aspects of many different agile tool types from physical tools, such as task boards and cards, to web-based agile tools that offer all-round solutions for application lifecycle management. In addition to these two extremities, there is also a wide range of lighter agile tools that focus on the core agile practices, such as backlog management. Also other non-agile tools, such as bug trackers, can be used to support agile development, for instance, with plug-ins. To investigate the special tool requirements in agile embedded development, the author observed tool related issues and solutions in a case study involving three different companies operating in the field of embedded systems development. All three companies had a distinct situation in the beginning of the case and thus the tool solutions varied from a backlog spreadsheet built from scratch to plug-in development for an already existing agile software tool. Detailed reports are presented of all three tool cases. Based on the knowledge gathered from agile tools and the case study experiences, it is concluded that there are tool related issues in the pilot phase, such as backlog management and user motivation. These can be overcome in various ways epending on the type of a team in question. Finally, five principles are formed to give guidelines for tool selection and usage in agile embedded systems development.

The requirements and needs of global data usage in product lifecycle management

This study was done for ABB Ltd. Motors and Generators business unit in Helsinki. In this study, global data movement in large businesses is examined from a product data management (PDM) and enterprise resource planning (ERP) point-of-view. The purpose of this study was to understand and map out how a large global business handles its data in a multiple site structure and how it can be applied in practice. This was done by doing an empirical interview study on five different global businesses with design locations in multiple countries. Their master data management (MDM) solutions were inspected and analyzed to understand which solution would best benefit a large global architecture with many design locations. One working solution is a transactional hub which negates the effects of multisite transfers and reduces lead times. Also, the requirements and limitations of the current MDM architecture were analyzed and possible reform ideas given.  

A deterministic model for lake clarity; application to management of Lake Tahoe (California-Nevada), USA

This dissertation has as its goal the quantitative evaluation of the application of coupled hydrodynamic, ecological and clarity models, to address the deterministic prediction of water clarity in lakes and reservoirs. Prediction of water clarity is somewhat unique, insofar as it represents the integrated and coupled effects of a broad range of individual water quality components. These include the biological components such as phytoplankton, together with the associated cycles of nutrients that are needed to sustain their popuiations, and abiotic components such as suspended particles that may be introduced by streams, atmospheric deposition or sediment resuspension. Changes in clarity induced by either component will feed back on the phytoplankton dynamics, as incident light also affects biological growth. Thus ability to successfully model changes in clarity will by necessity have to achieve the correct modeling of these other water quality parameters. Water clarity is also unique in that it may be one of the earliest and most easily detected wamings of the acceleration of the process of eutrophication in a water body.

Application execution management on the InteGrade opportunistic grid middleware

The InteGrade project is a multi-university effort to build a novel grid computing middleware based on the opportunistic use of resources belonging to user workstations. The InteGrade middleware currently enables the execution of sequential, bag-of-tasks, and parallel applications that follow the BSP or the MPI programming models. This article presents the lessons learned over the last five years of the InteGrade development and describes the solutions achieved concerning the support for robust application execution. The contributions cover the related fields of application scheduling, execution management, and fault tolerance. We present our solutions, describing their implementation principles and evaluation through the analysis of several experimental results. (C) 2010 Elsevier Inc. All rights reserved.

Lifecycle Information Management of a Mass Customized Product

Diplomityön tavoitteena on tutkia mitä uusia tiedonhallinnallisia ongelmia ilmenee, kun massaräätälöidyn tuotteen tuotetieto hallitaan läpi tuotteen elinkaaren, sekä miten nämä ongelmat voitaisiin ratkaista. Ongelmat ja haasteet kerätään kirjallisuuslähteistä ja massaräätälöintiprosessi yhdistetään PLM-vaiheisiin. Ratkaisua tutkitaan testaamalla kuinka standardit STEP ja PLCS sekä standardeja tukeva PLM järjestelmä voisivat tukea massaräätälöidyn tuotteen elinkaaren tiedonhallintaa. MC tuotteiden ongelmia ovat tuoterakenteen monimutkaisuus, jäljitettävyys ja muutosten hallinta läpi elinkaaren. STEP ja PLCS pystyvät kummatkin tahollaan tukemaan tiedonhallintaa. MC-tuotteen geneerinen tuoterakenne on kuitenkin manuaalisesti liittettävä elinkaaritiedon tukemiseen. PLM-järjestelmä pystyy tukemaan MC-tuotteiden elinkaarta, mutta koska toiminto ei ole järjestelmään sisäänrakennettuna, MC-tuotteiden tukemisen parantamisessa on edelleen haasteita.

Authoring tools and management information systems: study of a generalizable architecture

The need to effectively manage the documentation covering the entire production process, from the concept phase right through to market realise, constitutes a key issue in the creation of a successful and highly competitive product. For almost forty years the most commonly used strategies to achieve this have followed Product Lifecycle Management (PLM) guidelines. Translated into information management systems at the end of the '90s, this methodology is now widely used by companies operating all over the world in many different sectors. PLM systems and editor programs are the two principal types of software applications used by companies for their process aotomation. Editor programs allow to store in documents the information related to the production chain, while the PLM system stores and shares this information so that it can be used within the company and made it available to partners. Different software tools, which capture and store documents and information automatically in the PLM system, have been developed in recent years. One of them is the ''DirectPLM'' application, which has been developed by the Italian company ''Focus PLM''. It is designed to ensure interoperability between many editors and the Aras Innovator PLM system. In this dissertation we present ''DirectPLM2'', a new version of the previous software application DirectPLM. It has been designed and developed as prototype during the internship by Focus PLM. Its new implementation separates the abstract logic of business from the real commands implementation, previously strongly dependent on Aras Innovator. Thanks to its new design, Focus PLM can easily develop different versions of DirectPLM2, each one devised for a specific PLM system. In fact, the company can focus the development effort only on a specific set of software components which provides specialized functions interacting with that particular PLM system. This allows shorter Time-To-Market and gives the company a significant competitive advantage.
