Larox Corporation is a provider of full service filtration in solid and liquid separation. Larox develops, designs, manufactures and supplies industrial filters. By Larox’s continuous development principle, a project for more efficient production was started. At the same time production planning was taken under review. Aim for this Master’s thesis was to find software designed for production planning purposes replacement for old Microsoft Excel based method. In this Master’s thesis current way of production planning was thoroughly analyzed and improvement targets were specified and also requirements for new software were assigned. Primary requirements for new software were possibility to production scheduling, planning, follow-up and also for long-time capacity planning and tracking. Also one demand was that new software should have data link to Larox’s current ERP-system. Result of this Master’s thesis was to start using Larox’s ERP-system also for production planning purposes. New mode of operation fulfils all requirements which were placed to new system. By using new method of production planning, production planners can get more easier and reliable data than from current system.

CLASSIFICATION OF FOREST ROADS AND DETERMINATION OF ROUTE USING GEOGRAPHIC INFORMATION SYSTEM

ABSTRACT Geographic Information System (GIS) is an indispensable software tool in forest planning. In forestry transportation, GIS can manage the data on the road network and solve some problems in transportation, such as route planning. Therefore, the aim of this study was to determine the pattern of the road network and define transport routes using GIS technology. The present research was conducted in a forestry company in the state of Minas Gerais, Brazil. The criteria used to classify the pattern of forest roads were horizontal and vertical geometry, and pavement type. In order to determine transport routes, a data Analysis Model Network was created in ArcGIS using an Extension Network Analyst, allowing finding a route shorter in distance and faster. The results showed a predominance of horizontal geometry classes average (3) and bad (4), indicating presence of winding roads. In the case of vertical geometry criterion, the class of highly mountainous relief (4) possessed the greatest extent of roads. Regarding the type of pavement, the occurrence of secondary coating was higher (75%), followed by primary coating (20%) and asphalt pavement (5%). The best route was the one that allowed the transport vehicle travel in a higher specific speed as a function of road pattern found in the study.

Computational modeling for irrigated agriculture planning. Part II: risk analysis

Techniques of evaluation of risks coming from inherent uncertainties to the agricultural activity should accompany planning studies. The risk analysis should be carried out by risk simulation using techniques as the Monte Carlo method. This study was carried out to develop a computer program so-called P-RISCO for the application of risky simulations on linear programming models, to apply to a case study, as well to test the results comparatively to the @RISK program. In the risk analysis it was observed that the average of the output variable total net present value, U, was considerably lower than the maximum U value obtained from the linear programming model. It was also verified that the enterprise will be front to expressive risk of shortage of water in the month of April, what doesn't happen for the cropping pattern obtained by the minimization of the irrigation requirement in the months of April in the four years. The scenario analysis indicated that the sale price of the passion fruit crop exercises expressive influence on the financial performance of the enterprise. In the comparative analysis it was verified the equivalence of P-RISCO and @RISK programs in the execution of the risk simulation for the considered scenario.

Warning system based on theoretical-experimental study of dispersion of soluble pollutants in rivers

Information about capacity of transport and dispersion of soluble pollutants in natural streams are important in the management of water resources, especially in planning preventive measures to minimize the problems caused by accidental or intentional waste, in public health and economic activities that depend on the use of water. Considering this importance, this study aimed to develop a warning system for rivers, based on experimental techniques using tracers and analytical equations of one-dimensional transport of soluble pollutants conservative, to subsidizing the decision-making in the management of water resources. The system was development in JAVA programming language and MySQL database can predict the travel time of pollutants clouds from a point of eviction and graphically displays the temporal distribution of concentrations of passage clouds, in a particular location, downstream from the point of its launch.

Identification, assessment and ordering of concepts for agro-energy planning and possibilities of spatial analysis

ABSTRACT The present study aims to present the main concepts of the sugarcane straw to energy planning. Throughout the study, the subject is contextualized highlighting broader aspects of sustainability, which is considered the main driver towards agro-energy modernization. Concerning sugarcane straw, we first evaluated its availability regarding technical and economic aspects, and then it summarized the straw production chain for energy supply purposes. As a proposal to support agro-energy planning, it is presented some spatial tools that have been barely used in the Brazilian energy planning context so far. Therefore, working on straw to electricity associated with supply chain basis, we developed a conceptual model to spatially assess this bioenergy system. Using the model proposed, it is described the whole supply chain at state level, which accounted the potential of a single mill to explore straw, as well as main costs associated with straw acquisition, investments on the straw recovery routes and electricity transmission. Bearing these concepts in mind, it is fully believed that spatial analysis can bring important information for agro-energy action plans.

Suorituskyvyn mittaaminen pk-sektorin asiantuntijayrityksessä

Suorituskyvyn mittaaminen huolellisesti suoritettuna tuo yritykselle monia hyötyjä. Mittariston avulla yritys pystyy kohdistamaan liiketoimintaansa palvelemaan paremmin strategisia tavoitteita. Työssä käsitellään suorituskyvyn mittaamista pk-sektorin asiantuntijayrityksen näkökulmasta. Suorituskyvyn mittaaminen on ollut perinteisesti aikaisemmin huomattavasti suositumpaa lähinnä tuotanto- ja palveluyrityksissä. Työssä oli tavoitteena suunnitella pk-sektorin asiantuntijayrityksen käyttöön soveltuva suorituskykymittaristo. Pk-sektorin yrityksissä suorituskyvyn mittaaminen ei ole vielä saavuttanut suurta suosiota. Tämä johtuu osaltaan pk-yritysten vähäisistä käytettävissä olevista resursseista. Tästä johtuen myös mittariston suunnitteluprosessi on yrityksille haastavampi. Asiantuntijayritysten ominaispiirteet tuovat myös omanlaiset haasteet suorituskyvyn mittaamiseen. Asiantuntijayritysten tärkein resurssi on usein henkilöstön tietotaito ja sen takia suorituskykymittaristoissa korostuu usein juuri aineettomien tekijöiden mittaaminen. Oikein suoritettu suorituskykymittariston suunnittelu vaatii huolellista paneutumista mittariston suunnitteluprosessin eri vaiheisiin. Mittaristo tulee johtaa oikein määritetyistä yrityksen visiosta ja strategioista. Tärkeää on myös yrityksen henkilöstön sitouttaminen mittariston suunnitteluun. Suunnittelu vaatii täsmällisyyttä ja johdonmukaisuutta, joka saavutetaan noudattamalla jotakin tiettyä suunnitteluprosessin vaiheet sisältävää prosessimallia. Pk-sektorin asiantuntijayrityksissä suunnittelu vaatii erityisesti tarkkuutta mittariston näkökulmien ja mittareiden valitsemisessa. On mietittävä miten pk-yrityksen vähäiset resurssit saadaan riittämään mittaamaan hankalia ja resursseja vieviä aineettomia tekijöitä, jotka ovat yleensä kuitenkin asiantuntijayrityksissä usein erittäin tärkeässä asemassa.

The Design and Implementation of a Power Management Feature to a Configuration Management System

Green IT is a term that covers various tasks and concepts that are related to reducing the environmental impact of IT. At enterprise level, Green IT has significant potential to generate sustainable cost savings: the total amount of devices is growing and electricity prices are rising. The lifecycle of a computer can be made more environmentally sustainable using Green IT, e.g. by using energy efficient components and by implementing device power management. The challenge using power management at enterprise level is how to measure and follow-up the impact of power management policies? During the thesis a power management feature was developed to a configuration management system. The feature can be used to automatically power down and power on PCs using a pre-defined schedule and to estimate the total power usage of devices. Measurements indicate that using the feature the device power consumption can be monitored quite precisely and the power consumption can be reduced, which generates electricity cost savings and reduces the environmental impact of IT.

Building object-oriented software with the D-Bus messaging system

Object-oriented programming is a widely adopted paradigm for desktop software development. This paradigm partitions software into separate entities, objects, which consist of data and related procedures used to modify and inspect it. The paradigm has evolved during the last few decades to emphasize decoupling between object implementations, via means such as explicit interface inheritance and event-based implicit invocation. Inter-process communication (IPC) technologies allow applications to interact with each other. This enables making software distributed across multiple processes, resulting in a modular architecture with benefits in resource sharing, robustness, code reuse and security. The support for object-oriented programming concepts varies between IPC systems. This thesis is focused on the D-Bus system, which has recently gained a lot of users, but is still scantily researched. D-Bus has support for asynchronous remote procedure calls with return values and a content-based publish/subscribe event delivery mechanism. In this thesis, several patterns for method invocation in D-Bus and similar systems are compared. The patterns that simulate synchronous local calls are shown to be dangerous. Later, we present a state-caching proxy construct, which avoids the complexity of properly asynchronous calls for object inspection. The proxy and certain supplementary constructs are presented conceptually as generic object-oriented design patterns. The e ect of these patterns on non-functional qualities of software, such as complexity, performance and power consumption, is reasoned about based on the properties of the D-Bus system. The use of the patterns reduces complexity, but maintains the other qualities at a good level. Finally, we present currently existing means of specifying D-Bus object interfaces for the purposes of code and documentation generation. The interface description language used by the Telepathy modular IM/VoIP framework is found to be an useful extension of the basic D-Bus introspection format.

Improving alumni administration by self-built information system : building IMMIT connected' to enhance alumni connection

Alumni are considered as precious resource of the institutions, thus improving alumni adminis-tration is critical. In information era, alumni administration is assisted by widespread information technology, such as social network sites. This paper aims to discover if a self-built information sys-tem would enhance alumni connection in the IMMIT context, and what kind of attributes would be helpful applying to the special context. The current online alumni services at other universities and at the IMMIT host university are analyzed, and then social media is introduced. After illustrating the social capital existing in IM-MIT, the type of the self-built information system is suggested, following an interpretation of the prototype. Two research models are utilized in this article: TAM and intentional social action model. The second model is adjusted with proposed parameters. Afterwards, a survey and an interview protocol are designed under the guidance of the models. The results are analyzed in several groups, and the proposed parameters are tested. A conclusion is drawn to indicate how to improve alumni‟s intention to use and how to achieve a better-accepted design.

Asiakkaan osallistuminen palvelunkehitysprossiin

Suomessa on uudistuneen jätelain tavoitteena jätteiden lajittelun tehostaminen ja jätemäärien pienentäminen. Tutkimuksen tavoitteena oli selvittää miten asiakas voi osallistua uuden palvelun kehittämisprosessiin. Empirian kautta vastattiin kysymyksiin millainen on asiakkaan halukkuus ja valmius osallistua palvelunkehittämiseen ja mikä on asiakkaiden palaute palvelun ominaisuuksista. Tutkimus toteutettiin tapaustutkimuksena, jossa tutkittavana oli Aalto-yliopiston jätteiden raportointi- ja suunnittelupalvelun (Kierrätyspalvelin) palvelunkehitysprosessi. Tiedonkeruumenetelmänä oli yksilö- ja ryhmäteemahaastattelut. Tutkimustuloksena esitettiin Kierrätyspalvelimen palvelunkehitysprosessin malli. Tärkeimpänä tutkimuksellisena havaintona oli, että haastateltavat toimivat lähinnä tiedonlähteinä tarpeistaan. He osallistuivat palvelun ominaisuuksien testaukseen ja määrittelyyn.
