In today‟s manufacturing environment, different parts manufactured in-house and bought from suppliers are often assembled together into a finished product. Competition has made it very important for companies to deliver a customized product on a promised date. However, when inventory items are missing at the time of production, lead times for products become uncertain and this makes it difficult to fulfill a customer order on the promised date. It is thus important to explore the causes of missing items at the time of production in order to solve such a problem. This Master of Science thesis carried out through a case study at Fläkt Woods in collaboration with Jönköping University is about the problem of not finding specific inventory items in the locations specified by the computer system. It is delimited to inventory items which are physically within the company premises or which according to the computer system are within the premises of the company. The questions at issue have been what the causes of the problem of missing items within the company are and how to effectively reduce the problem. The thesis has been carried out over an entire academic semester as a full-time work in the company. The sources of the problem have been found to be the result of the work procedure, the underlying software used during work (the in-house developed ERP system), stealing from orders, ineffective barcode scans, re-sequencing at the component manufacturing department (called pre-manufacturing in the company) due to the need to fulfill multiple objectives, set-up times at the component manufacturing department and human errors among others. The suggestions given include: modification of the work procedure and the underlying software used at work, increasing effective scanning and using some checks at critical points in the material flow. Areas for further research are given to further reduce the impact of the problem on the production system.

Introduction: In today’s global world, supply chain and logistics operations have become far too complicated to be handled by individual firms. Nowadays, it is dealt by logistics and freight solution providing companies. The companies introduce an amount of flexibility for the firms doing their business. The performance of supply chain operations depends upon various dimensions such as location, quality, on-time delivery, dependability and cost. Reducing the operational costs by increasing effectiveness of process helps to gain a competitive advantage. Background: Logistics is a highly labour intensive industry. The primary role of a distribution centre as a supply chain element is to sort and forward the incoming goods(parcels) as effectively as possible within the minimum time. Due to the varied physical attributes of incoming goods/parcels, the sorting process in distribution centres involves different handling techniques. One such technique is the use of a parcel sorter conveyor system, there are various factors based on which the output increases or decreases in such systems. Flexibility is a factor that is seldom compromised, thus failing to operate effectively when volume increases, reduce a competitive advantage for the any distribution centre. Purpose: The purpose is to identify reasons for ineffectiveness during the process and find improvement opportunities which enables a distribution centre to handle more volume on a daily basis. Case: This single case study is carried out at a regional distribution centre aiming to grow regarding the number of suppliers and volume of handled parcels. Findings: The sources of ineffectiveness and improvement opportunities were identified (some of the improvement opportunities are case specific). Discussions: The study provides evidence that errors which are thought to be caused due to human actions can have other root causes, a synergetic approach is suitable in situations where high interdependency of variables exist.   Conclusions: The study has focused on a single case study, conducting the similar type of study with other companies working within a similar environment can provide more generalisable evidence. Improvement should be seen with a mentality of sustaining, with high variability of changes occurring, there should be a focus towards continuous improvement as well.

Substantial benefits can be achieved through the adoption of lean type thinking earlier at the design stage to create more viable products. A complex design cannot be easily leaned out in production; therefore, the production of affordable and sustainable products requires effective lean design considerations at the conceptual level. The research presented in this thesis investigates and demonstrates the application of lean design for product enhancement. The aim of the research was to develop a novel lean design framework that would support the generation of product design with attributes such as maximise value, manufacturable, and operable with minimum waste and resources ensuring avoidable harm is eliminated. The framework consists of a systemised process which is organised in to phases and activities that provides a unique practical manner to lean out a design. The construction of the framework initiated with an extensive literature review and proceeded with an industrial field study which consisted of 34 interviews with 11 manufacturing companies in Europe. The findings were amalgamated to generate a lean design definition and principles which would form the foundations of the framework. A real-life industrial case study of an offshore oil/water separator was used to validate the framework. In conclusion, the lean design framework provides the necessary means by which a lean design can be achieved. As a result a functionally viable and enhanced design that is cheaper to manufacture through controlling waste and eliminating avoidable harm occurrence can be realised with minimal effort. The research makes the following contributions: (1) identification of essential elements in lean design, (2) generation of a lean design definition and principles, (3) Lean Design Framework development and (4) illustrative guidelines based on the framework to be used by designers in realising a lean product design.

This thesis presents an impedance control strategy for a novel powered hip exoskeleton designed to provide partial assistance and leverage the dynamics of human gait. The control strategy is based on impedance control and provides the user assistance as needed which is determined by the user’s interaction with the exoskeleton. A series elastic element is used to drive the exoskeleton and measures the interaction torque between the user and the device. The device operates in two modes. Free mode is a low impedance state that attempts to provide no assistance. Assist mode increases the gains of the controller to provide assistance as needed. The device was tested on five healthy subjects, and the resulting assistive hip torque was evaluated to determine the ability of the controller to provide gait assistance. The device was evaluated at different speeds to assess the gait speed adaptation performance of the controller. Results show that hip torque assistance range was between 0.3 to 0.5 Nm/kg across the subjects, corresponding to 24% to 40% of the maximum hip torque requirements of healthy adults during walking. The peak power provided by the system is 35 W on average and a peak power of up to 45 W.
