At this time there is an increasing emphasis in Florida on developing large, multipurpose complexes which include shopping, entertainment, and accommodations for tourists. In all cases a major design problem is people transportation. For best efficiency the primary mode of transportation, the car, must be exchanged for other people movers within the complex, which will afford more security, flexibility, and better movement of people to their ultimate destination. Economically speaking, this would not only conserve fuel, but would allow consolidation of automobile parking into a less desirable area and the grouping of facilities for more shopping and recreation convenience. An example could be typified by a large complex of scattered hotel/motels, which must handle people and their belongings efficiently. One such case is the hotel operations at Walt Disney World. At the present time, only the Polynesian and Contemporary hotels are operating; however, future hotels are planned. Permitting cars to drive directly to the hotel introduces much confusion, traffic congestions, and additional effort on the part of guests and host. A cursory review of WDW hotel operations reveals the alrge amount of effort which typically much be expended into processing the guests and their belongings to and from their room. To be meaningful any such study must include all aspects of guess processing and the interrelationships of the major functions, such as transportation, material handling, and guest treatment. Because of the size and complexity, this can only be done by simulation. This research used simulation to test the Guest Welcome Center concept. The proposed Walt Disney World Guest Welcome Center would feature a luggage unloading area, special parking lot for hotel guest vehicles, convenient reception and registrations, orientation for new guests, and transportation to the hotels and Theme Park. It would further feature luggage containerization, with a special container tram running to and from the hotels. A computer simulation model of the proposed Guest Welcome Center was developed, and its performance analysed. The measures of performance were the maximum length of waiting lines and the maximum number of facility service channels needed, both by hour of the day and the average waiting time spent by hotel guests at various locations. The model performance defined staffing requirements and floor space requirements for guest waiting lines and luggage storage. Further, the simulation study lent insight into the nature of the system and suggested changes which might improve it.

Long delays between harvesting and crushing of sugarcane lead to excessive deterioration in the quality of sugarcane. The aim of this project was to develop a computer based model of sugarcane harvesting and delivery systems that could be used to investigate methods of reducing harvest-to crush delays. A literature review was conducted and simulation modelling was chosen as the most appropriate modelling technique for the situation of sugarcane harvesting and delivery and the purposes of this project. The Arena modelling system was chosen as the simulation software with which to construct the model. A model was developed on the scale of a particular sugar mill and the area of farms supplying it with cane. The Sezela mill on the south coast of KwaZulu-Natal, South Africa was chosen as a case study on which to develop and test the model. The model integrated a harvesting and transport section which represented all the individual farms or combinations of farms in the area with a millyard section. After the model had been verified and validated, it was used to investigate the effect of a number of different scenarios of harvesting and delivery systems and schedules on harvest-to-crush delays in the Sezela mill area. The results of the experimental runs performed with the model indicated that the most significant decreases in harvest-to-crush delays could be brought about by matching harvesting, delivery and milling cycles as closely as possible. It was also evident that burn-to-cut delays where daily burning is not practised constitute a large proportion of overall harvest-to crush delays. The model proved to be useful in making comparisons between systems and in providing a holistic view of the problem of harvest-to-crush delays. Recommendations for future developments of the model include adding a mechanical harvesting component and making the model more easily applicable to other mill areas. / Thesis (M.Sc.Eng.)-University of Natal, 1998.

Utilizando esses resultados, desenvolvemos um algoritmo para a reconstrução intranodal da solução numérica visto que, em cálculos de malha grossa, soluções numéricas mais localizadas não são geradas. Resultados numéricos são apresentados para ilustrar a precisão do algoritmo desenvolvido. / In this dissertation the spectral nodal method SD-SGF-CN, cf. spectral diamond spectral Green's function - constant nodal, is used to determine the angular fluxes averaged along the edges of the homogenized nodes in heterogeneous domains. Using these results, we developed an algorithm for the reconstruction of the node-edge average angular fluxes within the nodes of the spatial grid set up on the domain, since more localized numerical solutions are not generated by coarse-mesh numerical methods. Numerical results are presented to illustrate the accuracy of the algorithm we offer.
