  3. 2. Capacity Constraints in Multi-Stage Production-Inventory Systems : Applying Material Requirments Planning Theory

    Författare :Thi Thu Thuy Huynh; Robert Grubbström; Ludvik Bogataj; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Requirements Planning; Laplace transform; Net Present Value; multi-stage multi-level production-inventory planning; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : In this thesis, capacity-constrained aspects of multi-level, multi-stage productionplanning are investigated. The aim has been to extend Material Requirements Planning Theory (MRP Theory) to cover more general problems dealing with capacity constraints, in particular when non-zero lead times are present and the processes take place in continuous time.

    Sammanfattning : Due to the trend of increasing environmental demands put on civil aviation, manufacturersof commercial aircraft engines meet increased pressure to reduce weight. Modernturbofan engines represent up to almost one tenth of an aircraft's total weight, meaning areduction of engine component weight of just 30 kg is estimated to reduce CO2 emissionsby 400 tonnes over the lifetime of a medium sized commercial aircraft.

  7. 5. The Industrial TransformationTowards the Circular Economy : Dynamics, Drivers and Constraints

    Författare :Armaghan Chizaryfard; Cali Nuur; Paolo Trucco; Emrah Karakaya; Allan Dahl Andersen; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Circular economy; industrial dynamics; evolutionary theory; closed loop supply; industry value chain; Industrial Economics and Management; Industriell ekonomi och organisation;

    Sammanfattning : The notion of the circular economy has recently been posited as a vital strategy to mitigate climate change. At the industrial level, the circular economy envisions socio-industrial transformation to closed-loop material systems. LÄS MER
