In the final of magistral work I investigate increase of efficiency of industrial companies. I am mostly concentrated in creation of model for increase of efficiency of manufacturing. That will mostly be appropriate for industrial companies that are specialized in metal manufacturing and welding. In the first part analysis of scientific – methodic literature on theme of manufacturing efficiency increase is described by me including the essential notions. I have investigated various aspects of manufacturing organization. I have deepen in principles of possession of manufacturing and have analyzed principles of selection of Lean tools paying attention on criteria set in companies. In the second part information about surveys of trends of development of industrial companies is being given. I have invoked data of the Department of statistics. Questionnaire has been concluded and sent to industrial companies. In the third part model of increase of manufacturing efficiency is chartered. Also model of installment stages is drawn and divided. In each stage installment steps are named together with which the tool appropriate for installment of this is offered. Advantage of the model is such that all steps are shown in priorities together with the offered tools. For i have been in lack of this after analyzing suggested by other authors, I have a mind that my model would be very helpful for the beginning companies for the installment of Lean. The final work is consisted of four parts:... [to full text] / Baigiamajame magistro darbe nagrinėju pramonės įmonių gamybos efektyvumo kelimą.

Sustainable Value Stream Mapping (Sus-VSM) builds upon traditional VSM to capture additional sustainability aspects of the product flow, such as environmental and societal aspects. This work presents research to expand the utility of Sus-VSM to supply chain networks, develop a general approach towards improving supply chain sustainability, and examine the benefits of implementing simulation and a design of experiments (DOE) style analysis. Metrics are identified to assess economic, environmental, and societal sustainability for supply chain networks and visual symbols are developed for the Supply Chain Sus-VSM (SC Sus-VSM) to allow users to easily identify locations where sustainability can be improved. A discrete event simulation (DES) model is developed to simulate the supply chain, allowing easier creation of future state maps, which are used to identify locations for sustainability improvement. A scoring methodology and DOE-style analysis are developed to collect more information from the supply chain. Results from the case study show that the SC Sus-VSM meets the goals desired, and that the DES model aids the goals of the map. It is also indicated that interventions in the supply chain should first focus on economic improvements, followed by societal and then environmental improvements to achieve the greatest supply chain sustainability.

The desire to develop a holistic framework for knowing and modelling in human enterprises is not new. Methodologies, such as Systems Dynamics, Soft Systems and the Viable Systems Model all claim a holistic perspective. Each of these approaches emphasises the interrelatedness of `things', rather than the `things' themselves. Thus, they avoid the possible fragmentation that can occur when elements within a situation are treated as if they exist independently. Unfortunately, the systems approaches flounder because they fail to reconcile knowledge with the path that brings it into being, or to satisfactorily deal with the concepts of order or communication in language. The Thesis, therefore, provides a greater clarification of these issues, in the light of enactive cognitive science, chaos theory and contemporary theories on dialogue. As a result, a new framework is presented, for knowing and modelling in human enterprises, that is based on our `new' understanding of holism. The organisational context of the Thesis is provided by two generic models, both developed by the author (a model of Duopoly Competition and a model of Chaos Control ), together with a case study of the Danish hearing aid manufacturer Oticon. The Thesis concludes by presenting various insights arising from our new frame of reference and reflecting on their challenges for organisations.

The objective of this project is to improve productivity and efficiency for the inbound material handling operations in the warehouse of DC Älmhult. After three weeks pre-study in place of the distribution center, the authors have observed several problems existing in the current production, among which three types of wastes are found and analyzed by using VSM that are pick and drop, operator waiting time and inefficient transport. Two typical cases chosen from the inbound production are analyzed to reflect the current process and address problems. Fish-bone tool is used to identify wastes and roots. To eliminate or reduce the wastes, recommendations and solutions are developed by creating continuous flow combining with internal transport optimization. Future-state VSMs are drawn based on the suggested changes in line with continuous flow. Different productions models are simulated by elaborately developed excel sheets. A „distance table‟ is developed by using Microsoft Excel to help the loading or unloading leaders with the gate steering function so as to minimize internal transport distance. A new layout of the conveyor system is also suggested to lower the idle transport rate.

Authors        Jonathan Kölemo (890303) and Simon Jensen (870212)                         Title              Goodbye to Inbound and Outbound waste - A case study at IKEA’s Distribution                      Centre, Älmhult   Background The DC in Älmhult is working in two administrative teams; Inbound and Outbound. The relationship between and inside the Inbound and Outbound teams are complex and unclear. This increases the risk for bad and unnecessary work. The teams’ are handling tasks regarding planning and scheduling for unloading and loading shipments. The complexity at the DC in Älmhult also makes it difficult for managers to control and understand the whole flow within the two teams. The problem is based on complicated and unsynchronized tasks, poor utilization of IT systems and lack of integration and standardization within the teams work.   Purpose        The purpose with the thesis is to identify wastes within the teams’ work, and thereby provide suggestions for improvements.                 Method         A positivist approach has been used as a scientific perspective throughout the study. The scientific approach is deductive and the research strategy is qualitative. From the theoretical and empirical material an analysis has been designed that eventually lead to a conclusion.   Results            The study shows that both the Inbound and Outbound teams’ processes consist of a number of wastes. By using One-piece-flow, Standardization, Capacity and FIFO theories, the wastes can be reduced or completely eliminated.   Conclusions The most critical wastes have been chosen and by combining the four improvement theories, reductions of unnecessary activities can be made. By implementing the suggested improvements, the number of unnecessary activities can be reduced, and the total process and lead times will decrease. By doing this, the Flow planners can focus on more important activities and the same amount of staff can handle increased throughput of goods.

The aim of this project is to establish whether video self-modelling is an effective approach in decreasing fear responses in children with ASD aged between five and 15 years. Participants were recruited through a flyer that was posted in the Autism New Zealand Canterbury newsletter and the Autism in New Zealand Facebook page. Three participants were recruited who were aged 11 to 12 years, who had a diagnosis of ASD and a fear. This study used a single-case, AB design replicated across the three participants. The participants met with the researcher to discuss their fear and what the study entailed. Baseline measures were obtained and videos were created to depict the child being in the same environment as their feared stimulus. Participants watched their videos for a two-week period then the baseline measures were repeated twice. Two out of the three participants showed some increase in steps achieved in their fear hierarchies. A similar pattern was found with the self-reported levels of fear, one participant showed a decrease in post intervention measure, the second showed variability and the third was not able to complete the intervention due to his extreme fear response. The results of this study reflect some of the literature, which suggest that while VSM can result in rapid learning, in some cases it may not work for all participants and individual differences can account for some of this variability. Due to the variation in the results and individual differences, it is difficult to determine the effects of this type of intervention for fears and phobias in children with ASD. Limitations on this study included the number of participants, as a larger number would have provided more data on the effects of VSM for different participants and the amount of time that was allocated to complete the study.

Bakgrund: Att utveckla och förbättra organisationer genom effektivare användning av de resurser man har till förfogandet har blivit allt mer betydelsefullt under de senaste decennierna. Genom fokusering kring de aktiviteter som tillför värde hos kunden i slutprodukten kan företag reducera och eliminera oönskade slöserier inom tillverkningsprocessen. Ett verktyg som utvecklats och används för att eliminera dessa oönskade aktiviteter så som lagerhållning är Value stream mapping (VSM).   Problemformulering: Hur kan man identifiera slöserier samt dess förbättringsmöjligheter för att möjliggöra en högre produktionskapacitet genom frigörandet av anläggningsyta?¨   Syfte: Genom användandet av VSM som modell, identifiera slöserier och kostnadseffektiva förbättringsmöjligheter.   Metod: Denna fallstudie har utförts på ett företag som arbetar inom metallindustrin. Större delen av datainsamlingen har tagits från företagets egna dokumenterande data samt intervjuer med anställda och observationer under de besök författarna genomförde.   Slutsatser: Genom att använda VSM som en modell har författarna lyckats identifiera fallföretagets största faktorer till slöserier samt ge förslag och underlag till framtida förbättrings implementationer av förbättringsstrategier. Författarna har bevisat utifrån den teoretiska data studien är grundad på gentemot den empiriska att flertal förbättringsmöjligheter utöver den som företaget tänkt sig finns till deras förfogande vid eventuell framtida implementering.   Nyckelord Value stream mapping, VSM, slöseri, materialflöde, materialhantering, tillverkningsindustri, förbättringsstrategi

This research will focus on how applied the Time-based process mapping applied into the practical case. By comparing the difference between traditional process mapping tools and Time-based process map(TBPM), this research find out which kind of company and situation is suitable for TBPM and the reasons why the TBPM is suitable for this situation. The major research happens at IKEA’s DC terminal in Torsvik, Jönköping, Sweden. The holistic process will be mentioned in the beginning of the research, in order to better understand the current state in IKEA’s distribution centrel.
