In light of widespread digitization endeavors and ever-growing textual data generation, developing efficient academic Natural Language Processing (NLP) infrastructures, which can deal with large amounts of data, is of particular importance. Novel computation technologies allow tools that support big data and heavy computation while performing timely and cost-effective data processing. This development has led researchers to demand that knowledge be extracted from ever-increasing textual data before it is outdated. Cluster computation is a modern technology for handling big data efficiently. It provides distribution of computing and data over a number of machines in a cluster, as well as efficient use of resources, which are key requirements to process big data in a timely manner. It also assures applications’ high availability and fault tolerance, which are fundamental concerns when dealing with vast amounts of data. In addition, it provides load balancing of data during the execution of tasks, which results in optimal use of resources and enhances efficiency. Data-oriented parallelization is an effective solution to enable the currently available academic NLP infrastructures to process big data. This approach offers a solution to parallelize the NLP tools which comprise identical non-complicated tasks without the expense of changing NLP algorithms. This thesis presents the adaption of cluster computation technology to academic NLP infrastructures to address the notable features that are essential to process vast quantities of text materials efficiently, in terms of both resources and time. Apache Spark on top of Apache Hadoop and its ecosystem have been utilized to develop a set of NLP tools that provide a distributed environment to execute the NLP tasks. Many experiments were conducted to assess the functionality of the designated strategy. This thesis shows that using cluster computation technology and data-oriented parallelization enables academic NLP infrastructures to execute large amounts of textual data in a timely manner while improving the performance of the NLP tools. Moreover, these experiments provide information that brings a more realistic and transparent estimation of workflows’ costs (required hardware resources) and execution time, along with the fastest, optimum, or feasible resource configuration for each individual workflow. This knowledge can be employed by users to trade-off between run-time, size of data, and hardware, and it enables them to design a strategy for data storage, duration of data retention, and delivery time. This has the potential to enhance researchers’ satisfaction when using academic NLP infrastructures. The thesis also shows that a cluster computation approach provides the capacity to adapt NLP services with JIT delivery systems. The proposed strategy assures the reliability and predictability of the services, which are the main characteristics of the services in JIT delivery systems. Defining the relevant parameters, recording the behavior of the services, and analyzing the generated data resulted in the provision of knowledge that can be utilized to create a service catalog—a fundamental requirement for the services in JIT delivery systems—for each service offered. This knowledge also helps to generate the performance profiles for each item mentioned in the service catalog and to update them continuously to cover new experiments and improve service quality.

Bicycle leader brands have shift production overseas to reduce the cost of labor and to implement new technologies at lower cost. Bike manufacturer both in Asia and Europe employ a traditional way of production  based on economics of scale that aims cost per unit reduction. Where MRP systems and forecasting are part of their day basis operations. This traditional way of operation offers room for innovation that must be seen as a business opportunity. Thus, alternative management approaches can strengthen strategic goals and improve responsiveness and flexibility. Bicycle brands producing locally should implement alternative management systems to remain competitive, to take the maximum advantage of their location, to improve customer service and to cut operational cost. The course of action followed was a market analys is to understand the nature of the bicyclemarket within European Union. Similarly, a Business Process Reengineering was conducted to identify with the current operational processes and opportunities within the bicycle industry. Based on the Business Process Engineering, an alternative business model was presented. The main proposed solution to improve the current operational processes:  (a) Implementation of Just-­‐in-­‐time management system and relocation of assembly facilities.  (b) Benchmark IKEA core methods, designing products for supply chain and that customer assemble  the future themselves. (c) Benchmark Dell Computer business model of customization and supply chain. Finally, the fundaments for an alternative business concept were established regarding bicycle design concept, strategy planning and production system design.

Inventories totaling 1.7 trillion U.S. dollars represent an opportunity for U.S. manufacturers. This exploratory case study researched supply chain strategies used to manage inventory in manufacturing operations of a U.S. manufacturing company. A mature value chain contained within a single organization using the value chain framework was the basis for this study. Individual interviews conducted with 16 managers responsible for defining and implementing inventory control strategies, and 4 internal users provided primary information for the study. Other sources of information included a value chain map created through the observation of operations, various inventory measurements, and policies and guidelines related to managing inventory levels. An inductive content analysis employing zero-level coding of the interview transcripts identified 4 themes that describe inventory control strategies as economic order quantity, kanban, vendor managed inventory, and process integration. Physical observation of the value chain, review of supporting documents, and analysis of inventory data ensured the trustworthiness of interpreted themes. Findings identified no single inventory control strategy that fit all applications. Findings also revealed that the financial governing bodies' measurements were not the best tools for operational managers' improvement activities related to inventory control. Included are measures providing alternative means to gauge inventory efficiency. With the results of this study, managers may develop effective strategies to optimize inventory and improve material flow. Manufacturing managers improving material flow may promote sustainability of raw materials and business efficiencies through reduced waste, improved environmental conditions, and increased employment opportunities in associated communities.

Introduction: To stay relevant, it is required that companies work with continuous improvements.Finding inefficiencies is not always easy. One way to try to find inefficiencies is throughflow mapping. This study examines what causes inefficient activities for industrial servicecompanies. Purpose: The purpose of the study is to investigate how a workflow at an industrial servicecompany can be made more efficient with the help of flow mapping. Method: The study is conducted through a case study at a service industry company that maintainsand repairs motors and frequency converters. Flow mapping was used to map activitiesin the workflow and literature was collected to be able to conduct a flow mappingcorrectly. Interviews and observations have been used to support the flow mapping. Results: The company has two service workshops that have similar activities in their flow. Evenso, one of the workflows is more efficient than the other. Based on the comparison of theworkflows, inspiration has been used to adjust the workflow for the frequency converterworkshop. Using flow mapping and methods from lean, a future flow map has beencreated where non-value-added activities have been eliminated. Conclusion: Based on the results, several improvement proposals have been drawn up for thecompany's workshops. Industrial service companies can use flow mapping and VSM toeliminate non-value-added activities. Lean tools can be used to create order and structurethat lead to shorter lead times.

There is an urgent need to reduce emissions from maritime transportation to meet environmental targets set by international organizations and governments. To reduce emissions from maritime transportation, technical, market-based, and operational measures can be used. In this thesis, the focus is on operational measures, and in particular Just-in-Time arrival in the port call process. Just-in-Time arrival in the context of port calls refers to maintaining an optimal vessel sailing speed to arrive to the port when the availability of berth and other services are ensured. In earlier studies, the estimated fuel and emission savings potential of Just-in-Time arrival, is promising. Despite the promising potential of Just-in-Time, its implementation remains limited, with few real-world examples. The purpose of this thesis is to explore how to implement Just-in-Time arrival by studying coordination in the port call process.    Two research questions were formulated to address the purpose. The first aims to capture the potential benefits of implementing Just-in-Time arrival in port calls and the second aims to address what is required to implement Just-in-Time arrival in port calls. This thesis is based on two studies in the Swedish context. First, a quantitative study, in which Automatic Identification System data in combination with port call statistics and vessel-specific data were used to estimate the fuel and emission savings potential of Just-in-Time arrival. Second, a qualitative single case-study exploring the coordination mechanisms necessary for implementing Just-in-Time arrival in port calls was conducted.    The studies show that fuel and emission savings potential of Just-in-Time in previous studies is overestimated due to the assumptions used. Though, the implementation of Just-in-Time has potential to improve port call actors’ resource planning and utilization and increase the competitiveness of ports. This is because Just-in-Time arrival has the potential to aid actors in reaching mandatory emission reduction targets. To implement Just-in-Time arrival, it is necessary to coordinate the plans of actors. The required mechanisms to coordinate planning are pre-booking berth allocation policy and port community systems. The pre-booking policy implies booking time-slots for berths, facilitated by using the port community system. The port community system and the pre-booking policy enable the effective coordination of the planning processes of individual actors enabling Just-in-Time arrival in port calls. / Det är nödvändigt att minska utsläppen från sjöfartssektorn för att uppnå de klimatpolitiskamålen som har fastställts av internationella och nationella organisationer. För att minska utsläpp från sjöfarten och uppnå de klimatpolitiskamålen kan tekniska, policy, och operativa åtgärder användas. Fokus i denna avhandling är på operativa åtgärder, mer specifikt Just-in-Time ankomst vid hamnanlöp. Just-in-Time ankomst innebär att hålla en seglingshastighet som möjliggör ankomst till hamn vid den tidpunkt kajplatser och andra tjänster (exempelvis lotsning) är tillgängliga utan fördröjning. Tidigare studier visar att det finns en potential att spara bränsle och minska utsläpp genom att införa Just-in-Time ankomst. Trots potentialen är införandet av Just-in-Time ankomst begränsat i praktiken. Syftet med avhandlingen är att utforska hur Just-in-Time ankomst kan implementeras genom att studera koordineringen av aktörers aktiviteter under anlöpsprocessen.    Syftet uppnås genom att besvara två forskningsfrågor. Den första forskningsfrågan berör potentialen av införandet av Just-in-Time ankomst vid hamnanlöp. I den andra frågan undersöks hur olika koordineringsmekanismer kan användas för att koordinera hamnaktörerna för att realisera potentialen av Just-in-Time ankomst. Två studier har genomförts. Först gjordes en kvantitativ modellering för att uppskatta bränsle- och utsläppsbesparingar för Just-in-Time anlöp i Sverige, baserad på Automatic Identification System data, hamnanlöpstatistik samt fartygsdata. Därefter har en kvalitativ fallstudie genomförts som har utforskat hur olika koordineringsmekanismer kan användas för att koordinera enskilda aktörers planeringsprocesser under anlöpsprocessen samt undersöka potentialen av införandet av Just-in-Time ankomst.    Resultat visar att bränsle- och utsläppsbesparingspotentialen med Just-in-Time ankomst i tidigare studier ofta har överskattats på grund av antaganden som använts. Vidare framkom att implementering av Just-in-Time ankomst ha ett positivt inflyttande på aktörernas resursplanering- och utnyttjade och att hamnar kan öka sin konkurrenskraft tack vare sambandet mellan Just-in-Time ankomst och obligatoriska åtgärder för att minska utsläpp. För att kunna implementera Just-in-Time ankomst krävs förbättrad koordinering mellan aktörerna genom införandet av en förbokningspolicy av kajplatser. För att kunna förboka krävs förbättrad planerings och informationsdelning, det senare kan nås genom införandet av digitala informationsplattformar (port community system).
