The goods distribution companies are today controlled by customer needs and environmental goals. New customer needs that have arisen the past years are that the goods distribution should be ecologically sustainable and leave the lowest possible ecological footprint. There are several possible vehicle and routing concepts as well as system perspectives appropriate for product distribution. This study aims to investigate the appropriate concept that meets customer needs. KPI: s are used to measure the performance of companies. One problem with goods distribution by automobile transportation is the accessibility in the traffic that follows. Congestion, pedestrian- and one-way streets as well as to park decrease accessibility. The problem with replacing automobile vehicles with the chosen vehicle concept in this study, electric-powered cargo bikes, is that productivity risks to be degraded from a system perspective since the cargo volume is significantly smaller with an electric-powered bicycle. But the customer's framework conditions need to be followed and the goods distribution companies should also consider that environmental zones could be introduced in their municipalities. Various vehicles that are being used today worldwide to deliver goods are heavy trucks, light trucks, and bicycles. These deliveries are routed with a route optimization program. Vehicle load carriers are designed differently and therefore have different load capacities. High load capacity is an advantageous characteristic of productivity. With bicycle implementation, a reload point may be necessary if there is too long of a distance between the distribution center and the area of the recipient. This study is based on an explorative research purpose and an inductive research approach. The set questions of the study were answered mainly through qualitative research methods, but also quantitative research methods were used. The results show that an electric-powered cargo bicycle, called the Starke cycle, will be proposed to be implemented as a vehicle concept together with a movable transshipment point and a garage for the bicycles. A conclusion drawn by the study is that the customer's main need is to achieve an ecologically sustainable distribution. Suggestions for further research are to investigate more in route optimization and to investigate robotic solutions used for last mile. / Idag är det intressentbehov och ramvillkor som styr varudistributionsföretagen. Nya intressentbehov som uppkommit nu i närtid är att varudistribution ska vara ekologiskt hållbart och lämna det lägsta möjliga ekologiska fotavtrycket. Det finns flera möjliga fordons- och ruttplaneringskoncept samt systemperspektiv för varudistribution. Den här studien ämnar undersöka lämpligt koncept som tillgodoser intressentbehovet för ekologisk hållbarhet. KPI:er används för att mäta prestanda hos företag. Ett problem med distribution med bil är framkomligheten i trafiken. Trafikstockningar, enkelriktade gator och gågator samt att parkera försämrar framkomligheten. Problemet med att byta ut fossildrivna distributionsfordon till studiens valda fordonskoncept, eldrivna lastcyklar, är att produktiviteten kan försämras ur ett systemperspektiv, eftersom lastvolymen är betydligt mindre på en eldriven cykel. Men kundintressentens ramvillkor behöver följas och varudistributionsföretagen borde ta hänsyn till att miljözoner kan införas i deras kommuner. Fordon som idag globalt användas för att leverera gods är tung lastbil, lastbil och lastcykel. Dessa leveranser ruttplaneras med ett ruttoptimeringsprogram. Fordonens lastbärare är utformade olika och har därmed olika lastkapaciteter. En hög lastkapacitet är en fördelaktig egenskap för produktiviteten. Vid cykelimplementation kan en omlastningspunkt vara nödvändigt ifall avståndet mellan distributions-centralen och området med mottagarna är för långt. Studien har ett explorativt forskningssyfte och en induktiv forskningsansats. Frågeställningarna besvaras genom kvalitativa- och kvantitativa forskningsmetoder. En eldriven lastcykel, Starke cycle, föreslås implementeras som fordonskoncept. Detta tillsammans med en flyttningsbar omlastningspunkt och ett garage för cyklarna. Slutsatsen av studien är att kundintressentens främsta behov är att åstadkomma en ekologiskt hållbar distribution.

Este trabalho visa analisar uma proposta didática para o ensino do conceito de volume a alunos do Ensino Fundamental, tendo sido a mesma compartilhada junto a oito licenciandos do subprojeto Matemática PIBID/UFU na forma de um minicurso desenvolvido em três encontros de noventa minutos; este teve o intuito de resgatar as principais ideias dos alunos sobre o conceito de volume bem como coletar suas opiniões acerca da metodologia empregada. Com base na teoria da aprendizagem significativa de David Ausubel, teve-se por objetivos: (a) analisar a potencialidade do material apresentado, composto por dois tipos de atividades: aquelas que, por meio de questionamentos, discussões e manipulação de materiais visaram articular as grandezas volume, massa e conteúdo; e as que envolviam a solução de problemas envolvendo comparação, medição e produção de paralelepípedos; (b) analisar o desempenho dos licenciandos no desenvolvimento das atividades e (c) analisar as opiniões deles acerca do trabalho desenvolvido. Foram utilizada filmagem, gravação de áudio, registros fotográficos. A análise da aplicação da sequência indica que as questões e os problemas propostos favoreceram as articulações necessárias para a formação do conceito e que o material tem elementos para ser considerado como potencialmente significativo para a construção do conceito de volume e pode ser aplicado a alunos do ensino fundamental, desde que seja adaptado à sua realidade. / This work aims at analyzing a didactic proposal for the teaching of the concept of volume the elementary students, having been the same shared with eight students of the subproject Mathematics “PIBID/UFU” in the form of a short course developed on three dates of 90 minutes, this had to rescue the main ideas of the students about the concept of volume as well as to collect their views on the methodology employed. Based on meaningful learning theory of David Ausubel, had for objectives: (a) examine the potential of material presented, consisting of two types of activities: those who, by means of questions, discussions and handling materials aimed at articulating the volume, mass and content, and those that involve problem solving involving comparison, measurement and production of paving stones; (b) analyze the performance of students in the development of activities and (c) analyze their opinions about work. Were used in filming, audio recording, photographic records, the review of the implementation of the string that indicates that the issues and the problems proposed favored the joints necessary for the formation of the concept, and that the material has to be considered as potentially significant for the construction of the concept of volume and can be applied to elementary school students, since the discussions are adapted to their reality. / Dissertação (Mestrado)
