Optimization of Production Scheduling at IKEA Industry HultsfredAnemyr, Mattias January 2020 (has links)
IKEA Industry has factories in several locations where one location is in Hultsfred, Småland. IKEA Industry Hultsfred produces IKEA:s wardrobe collection PAX. In 2018, 2.8 million wardrobes were manufactured in Hultsfred. This thesis covers the subject of constructing and developing an optimization model which has the same characteristics as the plinth production at IKEA Industry Hultsfred. This means that the optimization model must consider production sequence; the setup time is different depending on which products that have been produced in the machine earlier. The thesis also covers to investigate how much time that is necessary to produce the plinths to Hultsfred, Portugal, and Germany under different circumstances. This thesis also balances inventory levels and setup time. I.e., how the inventory levels are changed if more emphasis is put into minimizing setup time, and the other way around. The results show that lower inventory levels and setup times are achievable over seven days if the production planning technique is changed.

Fangoso Lagoons: Hyperreality and Imaginary Stations in The Crying of Lot 49Glennon, Shane January 2022 (has links)
This essay analyses Thomas Pynchon’s novel The Crying of Lot 49 (1966) in relation to postmodern literary theory, specifically the concepts of hyperreality and imaginary stations. In Simulacra and Simulation (1981), Jean Baudrillard proposes that the Disneyland theme park in California is an imaginary station that conceals the fact that it is the world outside of Disneyland that is hyperreal. These ideas were developed further in relation to California by Umberto Eco in Travels from Hyperreality (1986). Baudrillard’s model is applied in this essay to the housing development of Fangoso Lagoons in The Crying of Lot 49. By analysing the mediums through which it is portrayed, how it is described and the events that occur there, Fangoso Lagoons is found to be similar to Baudrillard’s example of Disneyland because it is presented as an amazing, fantastic and bizarre spectacle. However, the true hyperreality lies outside of the development, in the novel’s semi-fictional California. This essay argues that Fangoso Lagoons is presented as hyperreal, similar to Baudrillard’s example of Disneyland or Umberto Eco’s example of Hearst Castle, but that it is in fact an imaginary station. As Baudrillard and Eco propose, the purpose of the imaginary station is to make the world outside appear as real through contrast. The imaginary station achieves this by feeding reality energy to its hyperreal surroundings.

The treatment of Historical space in selected works by Thomas PynchonKapp, W. January 2004 (has links)
Magister Artium - MA / The focus on space and spatiality is relatively new in literary studies and also not unproblematic. Problems arise from the way in which these concepts are constructed, described, defined and interpret~. It is possible to derive numerous kinds of space, such as historical space, physical space, metaphysical space and religious space, to name a few, from the structure or thematics of a novel. This in itself presents a problem, since the literary scholar must differentiate between these spaces in order to determine which will be most useful for study of a particular aspect. There does not seem to be a coherent theoretical position in literary scholar regarding space, and thus various views of theorists will be considered. Gullon (1975:21), in a seminal article on space entitled On Space in the Novel provides a possible definition of space, with reference to another seminal article, this time by Joseph Frank when he states that "Frank calls 'spatial' the form of those works that at a given instant in time concentrate actions that can be perceived, but not related, simultaneously". This definition denotes a further complication engendered by space, namely the notion that different spaces intersect and interrelate with each other, and consequently that it is very difficult - if not impossible - to separate the various kinds of literary spaces in order to analyse the occurrence of a single space in a text. It also seems bound to time, but in a sense bridges the temporal gaps in a novel since it brings together parts that are not necessarily adjacent to each other temporally. Time becomes spatialized by treating events in the novel as separate chunks which can be rearranged and linked to each other. 1bis creates a more coherent and comprehensive picture of events in a text. namely the notion that different spaces intersect and interrelate with each other, and consequently that it is very difficult - if not impossible - to separate the various kinds
of literary spaces in order to analyse the occurrence of a single space in a text. The main point in this regard seems to be creating patterns. This brings together more elements for the reader to be viewed at once, allowing him or her to attain a broader perspective on the text.

Improvements of an Inventory Control System with Simulation-based AnalysisRosén Berecz, Maja, Wallhagen, Fabian January 2023 (has links)
This thesis aims to improve the inventory control system of a company´s RDC in Norrköping, Sweden. Inefficiencies and non-optimal processes have been identified in the current system, which could negatively affect operations. The study addresses three questions: understanding the current system, identifying improvements, and adjusting the improved system to fit inventory control constraints. A literature review and case study were conducted, revealing lower service levels and higher costs than expected. Experimental scenarios were simulated to examine different improvements, such as using economic order quantity, different safety stock equations, and investigating service levels. / <p>Examensarbetet är utfört vid Institutionen för teknik och naturvetenskap (ITN) vid Tekniska fakulteten, Linköpings universitet</p>

Combinatorial Optimization for Data Center Operational Cost ReductionRostami, Somayye January 2023 (has links)
This thesis considers two kinds of problems, motivated by practical applications in
data center operations and maintenance. Data centers are the brain of the internet,
each hosting as many as tens of thousands of IT devices, making them a considerable global energy consumption contributor (more than 1 percent of global power
consumption). There is a large body of work at different layers aimed at reducing
the total power consumption for data centers. One of the key places to save power
is addressing the thermal heterogeneity in data centers by thermal-aware workload
distribution. The corresponding optimization problem is challenging due to its combinatorial nature and the computational complexity of thermal models. In this thesis,
a holistic theoretical approach is proposed for thermal-aware workload distribution
which uses linearization to make the problem model-independent and easier to study.
Two general optimization problems are defined. In the first problem, several cooling
parameters and heat recirculation effects are considered, where two red-line temperatures are defined for idle and fully utilized servers to allow the cooling effort to be
reduced. The resulting problem is a mixed integer linear programming problem which
is solved approximately using a proposed heuristic. Numerical results confirm that
the proposed approach outperforms commonly considered baseline algorithms and commercial solvers (MATLAB) and can reduce the power consumption by more than
10 percent. In the next problem, additional operational costs related to reliability
of the servers are considered. The resulting problem is solved by a generalization of
the proposed heuristics integrated with a Model Predictive Control (MPC) approach,
where demand predictions are available. Finally, in the second type of problems,
we address a problem in inventory management related to data center maintenance,
where we develop an efficient dynamic programming algorithm to solve a lot-sizing
problem. The algorithm is based on a key structural property that may be of more
general interest, that of a just-in-time ordering policy. / Thesis / Doctor of Philosophy (PhD) / Data centers, each hosting as many as tens of thousands of IT devices, contribute to a
considerable portion of energy usage worldwide (more than 1 percent of global power
consumption). They also encounter other operational costs mostly related to reliability of devices and maintenance. One of the key places to reduce energy consumption is
through addressing the thermal heterogeneity in data centers by thermal-aware work load distribution for the servers. This prevents hot spot generation and addresses the
trade-off between IT and cooling power consumption, the two main power consump tion contributors. The corresponding optimization problem is challenging due to its
combinatorial nature and the complexity of thermal models. In this thesis, we present
a holistic approach for thermal-aware workload distribution in data centers, using lin earization to make the problem model-independent and simpler to study. Two quite
general nonlinear optimization problems are defined. The results confirm that the
proposed approach completed by a proposed heuristic solves the problems efficiently
and with high precision. Finally, we address a problem in inventory management
related to data center maintenance, where we develop an efficient algorithm to solve
a lot-sizing problem that has a goal of reducing data center operational costs.

APPROACHING URBAN SUSTAINABILITY THROUGH RESTORATION ECOLOGY AND GREEN INFRASTRUCTURE / NATIVE PLANT PERFORMANCE ON A RIPARIAN BUFFER RESTORATION AND FEASIBILITY OF A CONSTRUCTED WETLAND AT AN URBAN PARKING LOTMatties, Reyna 17 November 2017 (has links)
Most cities are dominated by asphalt and concrete, which blocks the natural
movement of rain water. Wetlands, riparian buffers, and roadsides are being lost or
degraded in urban areas due to human development. Cities can be designed to benefit
humans and nature by using techniques from green infrastructure and restoration ecology
to improve urban sustainability. Parking lot M on McMaster University's west campus,
constructed in 1968 on a former floodplain, directs the highly saline parking lot runoff
into the adjacent Ancaster Creek. Natural groundwater sources along the surrounding
hillslopes are directed into pipes under the parking lot and into the creek. A one-hectare
riparian buffer restoration at lot M was used to assess the viability of depaving asphalt
and establishing native plants through a vegetation study. Total native plant biomass was
found to be similar to non-native plant biomass and was affected by road-salt salinity
from the parking lot. Species richness per quadrat was higher for non-native plants, and
greater for both non-native and native plants where less salt was present. Key
hydrological fluxes were examined at the parking lot that could contribute to a proposed
0.6 hectare constructed wetland on the parking lot, known as “McMarsh.” Potential
wetland water storage is in surplus year round, with an average storage of 265 mm/month.
Successful restorations require maintenance following the establishment of native species.
Management and maintenance of the restoration can help decrease non-native species.
Engaging with the community through outreach and education on restoration projects is
important for a successful restoration and increasing urban sustainability in cities. / Thesis / Master of Science (MSc) / Most cities are dominated by asphalt and concrete, which blocks the natural
