Kartläggning av databehov inom Scania Motortillverkning : Förberedelser inför digitalisering / Mapping of the key data needed at Scania Engine Manufacturing Preparing for Digitalization

Zong, Jianing, Shi, Yi January 2018 (has links)
I dagens samhälle befinner sig tillverkningstekniksindustrin i en övergångsfas på väg in i en digital era. Till skillnad från Industry 3.0 som involverar automatisering av enstaka maskiner och processer omfattar Industry 4.0 digitalisering och uppkoppling av alla aktiviteter i sin värdekedja. Mängden av tillgängliga data ökar hela tiden. Målet med detta examensarbete var att ta reda på vad digitalisering kan tillföra till Scanias motortillverkning med fokus på förbättring av nuvarande KPI:er (Key Performance Indicator). För att säkerställa att det ovanstående målet uppfylls formulerades nedanstående frågeställningar: • Hur kan Scania Motortillverkning förbättra KPI i bearbetningsprocesser genom insamling och analys av data från maskiner? o Vilka faktorer påverkar Scanias nuvarande KPI? o Vilka av dem har potential att utvecklas vidare eller styras genom införande av digitalisering? o Vilka maskindata är nödvändiga att samlas in för att öka KPI:er och på vilket sätt kan data samlas in? För att besvara frågorna och identifiera vilka data som kan tillföra nytta, användes främst kvalitativa metoder. Data samlades in från olika aspekter av genom praktik, observationer, intervjuer och studiebesök. För att kunna dra generella slutsatser och för att bekräfta hypoteser från de kvalitativa studierna utfördes även en kvantitativ studie som utförs på vevstakeline, genom sortering och analys av de befintliga insamlade data i dagens produktion. Efter en litteraturstudie kombinerad med intern informationssamling, kunde fokusområdet avgränsas ytterligare till OPE (Overall Production Effectiveness) som är väsentlig för produktiviteten och ofta inte når målvärdet i nuläget. Genom en analys av PUS (Produktionsuppföljningssystem) kunde faktorer som har en negativ inverkan på OPE tas fram. Genom intervjuer med olika funktioner inom Scania kunde författarna identifiera många konkreta parametrar, vilka kan fördelas till tre kategorier, Maskindata, Verktygdata och Processdata. En teknisk skanning av verktygs- och maskintillverkare genomfördes också för att kunna redogöra för vilka data som är möjliga att samla in med befintliga insamlingsmetoder.  Resultatet från detta examensarbetet bildar en utgångspunkt för att kunna digitalisera Scanias motorbearbetning, digitaliseringen kräver en del nya investeringar som författarna anser komma att löna sig på många plan. / The manufacturing industry is undergoing a transformation into a digital era. Industry 4.0 comprises digitization and connection of all aspects of its value chain, which results in more data being available and collected. The purpose of this degree project is to investigate the benefits that digitalization can bring to Scania’s engine manufacturing, with focus on improving the current KPIs (Key Performance Indicator). The following questions were formulated to ensure that this purpose could be reached: • How can Scania’s engine manufacturing improve KPIs in machining processes by collecting and analyzing data from machines?o What factors affect Scania’s current KPIs? o Which of the factors has the potential to develop further or control through the implementation of digitization? o Which machine data needs to be collected in order to improve KPIs and how can this data be collected? To answer these questions and investigate which data can be of use, a primarily qualitative method was initiated during the project. Information was collected from various aspects involved in production. This was done through observations, interviews and study visits. A quantitative study has also been performed to improve the generalizability of the thesis, by sorting and analyzing the existing collected data in the production line of the connecting rod. By combining literature studies with internal information gathering, the authors could further define the focus area to OPE (Overall Production Effectiveness), which is significant for productivity, and often does not reach the target value for Scania. Through an analysis of the data gathering from PUS (Production Follow-up System), factors that had a negative impact on OPE could be identified. The authors could also produce many concrete parameters by utilizing results from interviews of various functions within Scania. The parameters can be divided into three categories, Machine data, Tool data and Process data. A technical scan of tool and machine supplier has also been conducted to specify what data is possible to collect with the existing technology. The result of this degree project creates a starting point for digitalization of Scania’s engine manufacturing, which also results in potential new investments. According to the estimation of the authors, these investments will prove to be profitable on many levels over time.

Prestationsmätning inom företag med global produktionsstrategi : - En flerfallstudie på Volvo CE, Scania och Alfa Laval / Performance measurement in companies with a global production strategy

Johansson, Martin, Nyd, Mattias January 2016 (has links)
Bakgrund: Ökad decentralisering och ökade krav på kostnadseffektivitet har tillsammans med andra faktorer gjort att företag med global produktionsstrategi möter nya utmaningar när det kommer till att utforma prestationsmätningssystem. Få studier har gjorts i syfte att belysa hur ett vertikalt och horisontellt styrningsperspektiv kan användas för att utforma en effektiv prestationsmätning inom företag med global produktionsstrategi. Genom att möjliggöra integrering av ett vertikalt och horisontellt styrperspektiv kring prestationsmätning görs ett försök att lösa de utmaningar som finns kring att styra företag med global produktion. Syfte: Syftet med studien är att genom kartläggning, och jämförelse av prestationsmätning inom tre företag med global produktionsstrategi identifiera aspekter för en effektiv prestationsmätning med vertikal och horisontell styrning. Aspekterna ämnar mynna ut i en empiriskt förankrad referensram gällande prestationsmätning för företag med en global produktionsstrategi. Metod: Studien är en kvalitativ flerfallstudie på tre globala produktionsföretag. Teoretiskt material sammanställdes till en konceptuell modell som låg till grund för empiriinsamlingen. Datainsamlingen har skett genom intervjuer med personal på fallföretagen samt interna och externa dokument. Slutsats: Värdeskapande genom standardiserade produktionssystem har identifierats som viktigt för att kunna vara kostnadseffektiv med en global produktion. Dessutom blir en nedbrytning av vision och strategi och informationsutbyte mellan enheter viktigt för att skapa en likartad struktur i prestationsmätningen. För en effektiv styrning krävs även en mix av mått som även kan användas för jämförelser. Prestationsmätningen kan visualiseras med hjälp av ett kommunikationsverktyg som sammanlänkar olika enheter och möjliggör beslutsfattande på olika nivåer. / Background: An increased amount of decentralized production and cost efficiency has together with several other factors led to that companies with a global production strategy are facing new challenges when it comes to developing a performance measurement system. There is limited research in this area regarding how a vertical and horizontal management perspective can be used in order to successfully develop a performance measurement system for companies with a global production strategy. Purpose: The purpose of the study is through mapping and comparing of performance measurement, within three companies with a global production strategy; identify aspects needed for an efficient performance measurement with vertical and horizontal management. The aspects aim to build an empirical based framework for performance measurement regarding companies with a global production strategy. Method: This study is a qualitative multiple case study on three different companies. The theoretical foundation was compiled in a conceptual model which later was used to gather the empirical data. The gathering of data has been done through interviews on the companies and by studying internal and external documents. Conclusion: Creation of value through standardisation of production systems has been identified as one important aspect in order to cost effective. Further is the breakdown of vision and strategy important to create a similar structure of the performance measurement system. In order to manage effectively, a mix of performance measure is needed which also can be used for comparison. Performance measurement can be visualized by a communication tool which connects business units and enables decision making on different levels.

Optimization of the Haulage Cycle Model for Open Pit Mining Using a Discrete-Event Simulator and a Context-Based Alert System

Vasquez Coronado, Pedro Pablo January 2014 (has links)
The loading cycle in an Open Pit mine is a critical stage in the production process that needs to be controlled in detail for performance optimization. A comprehensive Alert System designed to notify supervisors of cycle times that are below the required performance standards is proposed. The system gives an alert message when one or several trucks are idle or the time of completing production tasks are over a predefined value. This alert is identified by the system and compared with pre-established Key Performance Indicators (KPIs) in order to determine corrective actions. The goal is to determine the strategies that help the production supervisor to optimize the haulage cycle model. A discrete-event simulator has been built in order to analyze different scenarios for route design and queue analysis. A methodology that utilizes different algorithms has been developed in order to identify the least productive times of the fleet. These results are displayed every time the simulation has finished. This research focuses on the optimization of haulage. However, the system is intended for implementation in subsequent stages of the production process, and the resulting improvement could impact mine planning and management as well. Topographic and drilling exploration data from a mine located hypothetically in the state of Arizona, were used to build a block model and to design an open pit; an Arena-based simulation was used to generate operating cycles that represent actual operations (As-Is model). Once the Alert System is implemented, adjustments were applied, and a new simulation was performed taking into consideration these adjustments (To-Be model), including comparative analysis and statistical results.

En este trabajo se aborda el problema de cómo obtener mayor rentabilidad a través de una correcta gestión de capacidad sujeta a un determinado nivel de servicio. El problema involucra a toda la organización y es común a industrias con capacidad limitada y, productos intangibles y perecibles. Se diseña un sistema de apoyo a decisiones inspirado en una visión sistémica y transversal a la organización cuyos principales elementos constitutivos son: producto, tecnología y recursos humanos. En el elemento producto, la metodología propuesta contempla: (i) el diagnóstico de la situación actual, (ii) análisis, definición e implementación de indicadores de desempeño y; (iii) evaluación de oportunidades a través de modelos de simulación. En el elemento tecnología, se contempla el levantamiento de un modelo conceptual del sistema y la definición de la arquitectura que permita mantener el sistema de apoyo propuesto en el tiempo. En el elemento recursos humanos, se adopta la metodología de la Matriz de Cambio para identificar las barreras y las facilidades al implementar el sistema propuesto. El estudio de caso considera la empresa de arriendo de equipos industriales AB S.A. Como principales resultados se encuentran: (i) una estrategia en balance oferta-demanda que considera la reducción de la capacidad en 42 equipos, de los 696 que existen actualmente (ii) un retorno esperado de 67.000 USD anuales por concepto de la reducción sugerida, monto que representa un 7% de la recaudación anual (iii) implementación de una plataforma de análisis de capacidad. Los resultados parciales son: a) Se estima que la capacidad ociosa representa un 36% de la recaudación anual; b) Los costos asociados a mantenimiento alcanzan el 12% de la recaudación anual; c) Se categorizan 70 equipos críticos bajo distintos indicadores de desempeño; d) Se identifica la información crítica para la implementación de la base de datos equipos-estado y clientes. e) Se recomienda crear dentro de la organización el cargo de analista en gestión de capacidad cuyas responsabilidades serán: implementación de la metodología, integración de las áreas servicios, sistemas y gestión de operaciones.

Identificación de clientes con patrones de alta interacción con los drivers de una tarjeta de crédito

Gallardo Mesa, Cristóbal Enrique January 2016 (has links)
Autor no autoriza el acceso a texto completo de su documento hasta el 4/3/2021. / Ingeniero Civil Industrial / El mercado del plástico crediticio se caracteriza por ser altamente competitivo y relevante al transar junto al débito, montos cercanos al 14% del PIB chileno, lo que ha generado constantes ofertas hacia los usuarios para incentivar el uso y gasto. Particularmente en la empresa a trabajar se ofrecen como incentivos (1) compras con cuotas, (2) acceso a promociones y (3) el canje en un club de puntos, caracterizados internamente como los drivers de la tarjeta de crédito. Estos drivers son relevantes de gestionar por que un 30% de las transacciones son realizadas con cuotas o descuentos, así como que el 35% de los clientes llega a niveles de canje, aumentando en los últimos años. Sin embargo, la empresa no conoce que tipo de cliente usa la tarjeta por un determinado incentivo. Por esta razón se generaron KPI que midieran la intención de uso de drivers, perfilando cerca de 300 mil clientes de alta interacción con cuotas y promociones, y cerca de 430 mil con el club de puntos, distribuidos en un diagrama de Venn. Con esta distribución se realizaron modelos de caracterización, obteniendo un mejor desempeño en puntos al capturar el 32% de los clientes en el mejor decil, seguido por cuotas con un 24% y en peor desempeño promociones con un 19%. Los principales resultados apuntan a perfiles distintos, donde (1) puntos son clientes con características de poder económico, uso de la página web y acumulación en rubros de la competencia directa, ejemplificado en que alguien que acumula en estos rubros es 1,83 veces más probable a tener una alta interacción que el resto. De manera contraria, (2) cuotas apunta a un bajo poder económico, nulo ingreso a la web y edad superior a 35 años, mientras que (3) promociones son menores de 30 años, con poder económico medio y un uso oportunista de la tarjeta. Posteriormente se extendió el análisis de puntos hacia principales líneas de premios, obteniendo además de perfiles más específicos, el efecto circulo virtuoso que los clientes canjean premios muy correlacionados a los rubros de acumulación. Finalmente se propuso gestionar a 660 mil clientes de baja interacción que el modelo señaló con los mejores lifts. Con esta acción se espera generar un gasto incremental de $12 MM, que es un 6,35% del gasto anual. Además se propone una gestión al largo plazo de los clientes, que en concordancia con los resultados, incentiven a los clientes con estos drivers según su etapa de vida y evolución económica, primero ofreciendo promociones y posteriormente puntos o cuotas.
