Kostnadsreduktion med VAVE-metoden : Den bortglömda metoden / Cost reduction using the VAVE-method : The forgotten method

Bäck, Jonathan, Callerud, Erik January 2016 (has links)
Examensarbetet har utförts på Swegon AB i Kvänum som utvecklar, tillverkar och säljer klimatanläggningar för inomhusbruk. Ledningen vill se en mer strukturerad hantering av de kostnadsreduceringsarbeten som Swegon utför på sina produkter. Swegon arbetar med kostnadsreducering genom att använda metoden VAVE (Value Analysis/Value Engineering). Uppdraget som gavs var att reducera rörliga kostnader på sortimentet Compact och för att klara detta vara koordinatorer i en VAVE. I uppdraget ingick även en granskning av metoden samt att lämna förbättringsförslag som leder till att både deltagare och ledning blir nöjda med arbetssättet. Åtgärderna som bör genomföras går främst ut på att minska resurser som krävs för att utföra en VAVE. Detta uppdrag resulterade i två frågeställningar: 1. Vilka förändringar kan hittas med VAVE, som minskar rörliga kostnader vid tillverkning av Compact-aggregat?   2. Finns det förbättringar som kan implementeras i Swegons VAVE?   För att besvara frågeställning ett krävs det fullt deltagande vid förberedelse inför workshopen och under workshopen. Något som inte har genomförts är deltagande efter workshopen då det hamnar utanför examensarbetets ram. För att besvara frågeställning två krävs en analys av metoden VAVE, jämförelser med liknande metoder och teorier och egna erfarenheter från den genomförda VAVEn. Intervjuer, observationer och dokumentstudie har utförts för att få den kunskaps som krävs för att besvara frågeställningarna.   Resultatet av arbetet är förslag på åtgärder som kan införas för att minska de rörliga tillverkningskostnaderna för Compact-sortimentet med hela 12,3 %. Åtgärderna består främst av omkonstruktion och byte av befintliga komponenter. De åtgärder som ger störst besparingar planeras att ta längre tid än tolv månader vilket resulterade i ett projekt som kommer att genomföras i framtiden när resurser är tillgängliga. Resultatet är även en förbättrad version av VAVE där överflödiga moment har plockats bort samt moment som kan förbättra resultatet har lagts till eller ändrats. De moment som har plockats bort är protypbyggnation innan workshop, relationsmatris och paretodiagram. De moment som har lagts till eller ändrats är produktspecifikation, kundkrav, produktkalkyl, utvärdering och presentation av workshop.   Vidare arbete som kan vara lämpligt är att undersöka resultatet av den nya versionen av VAVE genom att utföra den ett antal gånger och jämföra resultaten med Swegons nuvarande version. / This assignment was performed at Swegon AB in Kvänum, a company that develops, manufactures and sells indoor air conditioning systems. The head management was looking for a more structured method when trying to reduce costs on their products. When constructing a cost reduction evaluation, Swegon uses the VAVE method (Value analysis/Value engineering). The assignment was to reduce the variable costs on Swegons Compact assortment, as well as being coordinates in a VAVE-evaluation. Furthermore the assignment also included a review of the VAVE method and submitting suggestions on improvements that could be made to reduce costs at the same time as both employees and management are satisfied. The measures to be made are focused on reducing the costs of constructing a VAVE evaluation. This resulted in two questions: 1. What changes could be made by using VAVE that would reduce variable costs when manufacturing the Compact products? 2. Are there any improvements to be implemented in Swegons VAVE? To answer question one, full participation was needed both when preparing the workshop and during the workshop. As participation after the workshop are outside the frames of the assignment, that was left out. To answer question two, a thorough investigation of the VAVE method was needed, as well as a comparison to similar methods and experiences from the carried out VAVE. Interviews, observations and document analysis were also done in order to answer the questions in the best way possible. As a result, the assignment suggests implementations that would reduce the variable manufacturing costs on the Compact assortment by as much as 12.3%. The measures are focused on reconstruction and change of existing components. Measures giving the highest savings are estimated to run over more than 12 months and therefore resulted in a project that will be carried out in the future when resources are available. The assignment also resulted in an improved version of VAVE where unnecessary steps are removed and elements that can enhance the results are added or changed. The removed steps is make a prototype before the workshop, relationship matrix and pareto chart. The added or changed steps is product specification, customer demands, cost breakdown, evaluation and presentation of the workshop. Suggestions on further work in this area would be to evaluate the results of the new version of VAVE, by using it multiple times and then compare it to the version that Swegon currently uses.

Shela koma na mizimu mema - remembering our ancestors

Mahazi, Jasmin Anna-Karima 16 August 2012 (has links) (PDF)
Vave is generally defined as a corpus of agricultural songs as they are sung and performed by Bajuni farmers - an ethnic subgroup of the Swahili - on the eve of burning the bush, a stage of slash and burn cultivation. Although the song’s main theme is agriculture and each cultivation step in particular is given attention, an analysis of the aesthetics of Vave from the viewpoint of oral literature unearths the secret and sacred dimension of Vave performance. Death, bereavement, resurrection, and spirituality are, besides agricultural cultivation, the basic aspects of the Vave. Indeed the Vave performance may be more correctly recognised as an ancient religious rite which has ancestral worship as a central issue. Although the worship of ancestors is irreconcilable with the Islamic belief system, Vave is still performed by the Muslim Bajuni farmers today. This essay attempts to outline in which way the ancestors are annually remembered, revived or actualised in the present by Bajuni farmers through the performance of an oral tradition.
