    Abstract : Increasing congestion and environmental concerns have evoked an interest in promoting urban Public Transport (PT) the last decades. In 2012 the City of Stockholm adopted an “Urban mobility strategy” stating that public transport, cycling and walking should be prioritised over cars in central Stockholm. READ MORE

    Abstract : The focus of this thesis is needs in the context of health care priority setting. The notion of needs has a strong standing in health care policy; however, how the idea should be understood more specifically and how it should guide decisions about priority setting remain contentious issues.

  5. 3. On the Optimization of Schedules of a Multitask Production Cell

    Author : Karin Thörnblad; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mathematical optimization; flexible job shop scheduling; mixed integer linear programming MILP ; complexity analysis; mathematical modelling; production planning; multi-purpose machine; dispatching rule; priority function; total flowtime; total tardiness; release date; due date; due date;

    Abstract : Volvo Aero has invested in a complex production cell containing a set of multipurpose machines. The problem of finding optimal schedules for this multitask cell is a complex combinatorial optimization problem which is recognized as a flexible job shop problem. This thesis proposes an approach to find such schedules using mathematical optimization. READ MORE

  6. 4. Defunctioning stoma in low anterior resection of the rectum for cancer : Aspects of stoma reversal, anastomotic leakage, anorectal function, and cost-effectiveness
