Determining tactical operations policies for an auto carrier using discrete-event simulation

Du Plessis, Annemie J. 12 1900 (has links)
Thesis (MScEng (Industrial Engineering))--Stellenbosch University, 2008. / Passenger cars are either imported to or assembled in South Africa, and then distributed to the customer. An important part of the supply chain is formed by the auto carrier companies who do this distribution. The basis of this thesis is a study that was executed in collaboration with a South African auto carrier company, and the objective was to improve the long-distance auto carrier fleet management through improved tactical operational policies. These policies focus on application of the fleet by assigning transportation vehicles to routes, as well as the business rules that must be followed at pick-up and drop-off locations. Several rules were developed during this study, which, together with specific transportation vehicle (carriers) assignments, form operational scenarios. The quality of each scenario was evaluated using discrete event simulation over a six month time-span, and considering four decision parameters simultaneously. These parameters are 1) useful kilometres travelled by the long-distance carriers, 2) empty kilometres travelled by the same long-distance carriers, 3) the expected number of cars waiting to be transported and 4) the expected time it takes to deliver a car to its destination. A high level of uncertainty prevails in these transportation operations, while fluctuating demand calls for the dynamic allocation and management of carriers in order to sustain an acceptable service level in a cost-effective manner. The best tactical policies should maximize the number of cars delivered on time at the lowest cost. Major constraints considered are staff- and maintenance schedules. While searching for the best of several scenarios, multiple, conflicting criteria had to be evaluated, as mentioned above. Two multi-criteria decision analysis (MCDA) methods were used namely SAW and TOPSIS, while the Mahalanobis distance method was also applied as an evaluation technique. These methods were used to rank scenarios. Additionally, the application of Portfolio theory and the efficient frontier was investigated for applicability to the problem studied. An analogy to the efficient frontier providing an additional means for scenario selection and evaluation was developed. The result of this study provides the decision maker of the auto carrier company with a tactical decision aid, consisting of the MCDA and Mahalanobis scenario rankings, a cost-benefit graph and a fleet portfolio efficient frontier, to aid long-distance carrier management. Additionally, a sensitivity analysis was also done for strategic planning concerned with the sufficient long-distance carrier fleet size. The first part of this thesis comprises a study of literature in which freight operations, auto carrier studies and the auto carrier context in South Africa are investigated. The problem is formulated and a suitable formulation and solution tool identified. Multi-criteria decision analysis is also investigated in order to enable scenario evaluation. The solution development phase consisted of the simulation model concept development, acquisition of input data, model verification and validation, scenario construction, simulation execution, and analysis of results.

Significados da prática do turismo para portadores de esclerose múltipla em seu tempo de lazer

Santini, Heloisa 07 July 2006 (has links)
Os objetivos deste estudo foram investigar os significados das práticas do turismo por sujeitos portadores de esclerose múltipla (EM) em seu tempo de lazer, desvelando as reais condições desses portadores de EM, quanto à efetiva prática de lazer diante das possibilidades e limites desse sujeito. Nesse sentido, foi realizada uma revisão teórica e a dissertação foi dividida em capítulos que tratam da dialética do corpo na modernidade e o lazer, a realidade social dos sujeitos portadores de EM, os significados do lazer para sujeitos portadores de EM. Foi realizado um estudo preliminar exploratório ao tema e, a partir de uma amostra por tipicidade, o processo investigatório compreendeu movimentos reflexivos e críticos. As categorias de análise: lazer, turismo e qualidade de vida foram ressignificadas a partir do referencial proposto, reconstruindo a realidade vivenciada pelos sujeitos portadores de EM, por meio de estudo do comportamento manifesto em seu tempo de lazer. O estudo revelou que as práticas de lazer e de turismo significaram atividades prazerosas e condição de normalidade para ser e estar-no-mundo. / Submitted by Marcelo Teixeira (mvteixeira@ucs.br) on 2014-05-05T17:56:24Z No. of bitstreams: 1 DISSERTACAO HELOISA SANTINI.pdf: 775618 bytes, checksum: 66f216dbbeffa18cab1337d76c25206a (MD5) / Made available in DSpace on 2014-05-05T17:56:24Z (GMT). No. of bitstreams: 1 DISSERTACAO HELOISA SANTINI.pdf: 775618 bytes, checksum: 66f216dbbeffa18cab1337d76c25206a (MD5) / The purposes of this paper were to investigate the meanings of practices of tourism for people with Multiple Sclerosis (MS) in their leisure time, revealing the real conditions of them as in the effective practice of leisure facing the possibilities and limits of the subject. That way, it was done a theory review and the essay was divided in chapters that deal with the dialectic of the body in the modern times and the leisure itself, the social reality of the MS people, and the meanings of leisure for those people. It was done a preliminary exploratory study of the theme and, from a sample by type; the investigatory process has enclosed reflexive and critical movements. The categories of analyzes: leisure, tourism and quality were remeant from the proposed referential, rebuilding the living reality of the people with MS by a study of behavior in their time of leisure. The paper has revealed that practices of leisure and tourism have meant pleasure activities and conditions of normality to be and to be in the world.
