Ur led är tiden: En studie av metoder att korta ledtider inom forskning och utveckling

Product development cycles become shorter and shorter. The time from idea to market has become an important competitive factor. Despite this, methods used for making the product development process faster are surrounded with uncertainty about their efficiency. The purpose of the thesis is to describe the pros and cons of ?best practice? methods for shortening Lead times and how these methods effect the Lead times in research and development.

Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long Lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery Lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery Lead times.The study shows that the causes of the long delivery Lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Snabbast vinner? : en studie om hur e-handelsföretag inom modebranschen arbetar med korta ledtider

PurposeThe purpose of this thesis is to provide a deeper understanding of how e-commercecompanies within the fashion industry are working with Lead times and illustrate andanalyse differences and similarities between companies.Research question- In which ways are e-commerce companies within the fashion industry working withshort Lead times?MethodologyThis thesis is based on a qualitative research method in order to achieve a greaterunderstanding of the chosen topic, of how the chosen companies are operating and toprovide room to our own interpretations and reflections. Interviews through telephonewere used to gather the empirical data from six different e-commerce companies withinthe fashion industry.ConclusionsAfter completing the theoretical and empirical analysis it can be concluded that leadtimes are considered essential for all of the participating companies but there is adifference in which way they look at, and how they work with Lead times. Somecompanies stressed that short Lead times are an important aspect of competition andclaimed that this is something they are constantly working with. For others the balanceand matching of supply and demand was the most important factor rather than toachieve short Lead times.

Ledtidsanalys på Peltor AB med logisk gruppindelning på elektronikprodukter

This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery Lead times for each product.

Svensk asylpolitik : En studie kring styrning och långa handläggningstider på Migrationsverket

The Swedish Migration Board has during a long time had problems with long processing times for persons that apply for asylum. The government has set targets that investigation should not exceed 6 months although it is done in almost 70% of cases.The study's aim has been to examine if steering can be linked together to long processing times and, if so, explain why. The intention has not been to provide a comprehensive picture of the problem but has defined itself to ensure steering impact. The study has been carried out by studying relevant governing documents, previous research and by interviews with administrators and decision-makers in two of the Migration Board asylum units.The analyses of the study show that a combination of inadequate steering and inadequate resources have contributed to aggravate the implementation, which has lead to long processing times..

Flödesoptimering på sjukhuslaboratorium: En praktisk implementering av lean

This study has investigated the possibilities of implementing lean in a division of a hospital in Stockholm. The goal was to reduce the lead time for the patient to get his diagnose by implementing lean in the two production flows of this division. In order to accomplish it, a complete map over the value stream has been done. With the help of the value stream map and lean theory a list over the processes in contradiction with lean has been made. Finally propositions to implement lean and by this way reduce the Lead times in this stream have been made out.

Värdekedjeanalys av returflöden på Scania : Fallstudie på marknaderna i Sverige, Tyskland och Benelux

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the Lead times and the costs caused by the flow of material are hard to estimate.

Trimning av lead och lag filter

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

Realistisk restidsberäkning för comodal reseplanering

With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.An investigation of the available data on maps and travel times shows where the currently used methods are lacking.
