  1. 1. An ILP-model for the Train platforming problem

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Simon Calderon; [2023]
    Keywords : Optimization; Integer programming; Train platforming; Train scheduling; Optimering; Heltalsprogrammering; Tåg; Järnväg; Schemaläggning;

    Abstract : The goal of this thesis is to create an optimization model to optimize the routing of trains within railway stations. This problem is known as the train platforming problem, and the model we present is an integer programming model. By this model we aim to optimize factors such as walking distance, switch usage or platform usage. READ MORE

  3. 2. Job Shop Scheduling of Cold Rolling Mills in the Aluminum Industry

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Rasmus Eriksson; Niklas Herkevall; [2022]
    Keywords : Funktionell verkstad; flexible job shop scheduling; job shop scheduling; optimering; makespan; linjär heltalsprogrammering; matematisk programmering; MILP; schemaläggning; sekvensering.;

    Abstract : Studien genomfördes på industriföretaget Gränges Finspång AB som är en producent av valsade aluminiumprodukter för värmeväxlare vilka används som komponenter främst inom bilindustrin och värme, ventilation och luftkonditionering. Aluminium är en miljöeffektiv råvara tack vare materialets naturliga egenskaper samt dess återanvändbarhet vilket har lett till att allt fler företag vill ta vara på dessa egenskaper vid tillverkning av klimatsmarta produkter.

  4. 3. Optimisation of the Distribution of COVID-19 Vaccines

    University essay from KTH/Matematisk statistik

    Author : Paula Isacson; Daniel Maslov; [2021]
    Keywords : Mixed-integer program; stochastic program; supply chain management; reliability; Blandad heltalsprogrammering; stokastisk programmering; logistik av försörjningskedja; tillförlitlighet;

    Abstract : This paper explores how to optimally distribute vaccines by deciding what middle warehouses to use for storage. For this purpose, a network has been designed with a central warehouse, a set of middle warehouses and a set of local hospitals. READ MORE

  5. 4. Smart Choices of Logistic Flows in Autonomous Transport System

    University essay from KTH/Optimeringslära och systemteori

    Author : Hanna Ma; [2020]
    Keywords : Applied mathematics; mixed integer linear programming; logistic planning; Tillämpad matematik; blandad heltalsprogrammering; logistikplanering;

    Abstract : PLAS is a cloud-based software used for planning and scheduling fleets of vehicles for material transport. PLAS consists of two components; the Logistic Flow Solver (LFS) and the Material Transport Scheduler (MTS). Based on transportation requests, the LFS generates a set of logistic flows. READ MORE

  6. 5. Optimal Multi-Skilled Workforce Scheduling for Contact Centers Using Mixed Integer Linear Programming : A Method to Automatize Workforce Management

    University essay from KTH/Optimeringslära och systemteori
