  1. 1. Disruption Analysis - An Important Tool in Lean Production

    Författare :Johan Ericsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production technology; TPM.; Kaizen; JIT; Lean Production; Manufacturing system; Disruption; Downtime; Produktionsteknik;

    Sammanfattning : This thesis is divided in two parts which are strongly connected. Part one deal with disruptions occurring in connection with machine down-time, quality losses and increased cycle time. The analysis is based on 10 studies, in which down-time losses in Swedish industry have been registered. LÄS MER

  3. 2. A Composable and Extensible Environment for Equation-based Modeling and Simulation of Variable Structured Systems in Modelica

    Författare :John Tinnerholm; Adrian Pop; Martin Sjölund; Peter Fritzson; Christopher Rackauckas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Modeling and Simulation are usually used to solve real-world problems safely and efficiently by constructing digital models of Cyber-Physical Systems. The models can be simulated and analyzed with respect to requirements, and decisions about their design can be based on this analysis. LÄS MER

  4. 3. Optimization of Just-in-Time Sequencing Problems and Supply Chain Logistics

    Författare :Gyan Thapa; Sergei Silvestrov; Anatoliy Malyarenko; George Fodor; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Just-in-time; JIT sequencing; apportionment; product rate variation; output rate variation; algorithms; heuristics; supply chain; logistics; queueing; non-linear integer programming; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : This dissertation presents a comprehensive and comparative progress in sequencing approaches of mixed-model just-in-time (JIT) sequencing problem together with discrete apportioment problem (DAP). The goal of JIT sequencing problem (JITSP) is to keep the rate of usage of parts as constant as possible along the assembly lines, and the goal of DAP is to divide a given integer number of delegates proportionally among the states or the parties according to their population or votes.

  5. 4. Security in Physical Distribution - Causes, mitigation measures and an investment model

    Författare :Luca Urciuoli; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security investments.; security measures in supply chains; causes of security vulnerability; antagonistic risks; security; physical distribution;

    Sammanfattning : Recent statistics and terror events testify an increased vulnerability of distribution networks. Antagonistic threats as theft, counterfeiting, contamination and terror are burdening supply chains with unexpected costs in form of lost cargo, production downtimes, lower customer satisfaction, and higher transportation costs.

  7. 5. Security in Physical Distribution Networks - A Survey Study of Swedish Transport Operators

    Författare :Luca Urciuoli; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antagonistic threats.; supply chain security; cargo security; physical distribution security; transportation security; cargo theft; Quantitative Risk Assessment;

    Sammanfattning : The objective of this study is to understand what factors influence the security of physical distribution networks. Thereafter it aims to bring to light what security measures exist today to enhance security and finally how to determine the profitability of security investments. LÄS MER
