We address the problem of jointly determining shipment planning and scheduling decisions with the presence of multiple shipment modes. We consider long lead time, less expensive sea shipment mode, and short lead time but expensive air shipment modes. Existing research on multiple shipment modes largely address the short term scheduling decisions only. Motivated by an industrial problem where planning decisions are independent of the scheduling decisions, we investigate the benefits of integrating the two sets of decisions. We develop sequence of mathematical models to address the planning and scheduling decisions. Preliminary computational results indicate improved performance of the integrated approach over some of the existing policies used in real-life situations. / Singapore-MIT Alliance (SMA)

1 Abstract Legislation on transboundary shipments of waste This thesis focuses on the legal regulations of transboundary shipments of waste. The aim of the thesis is a comprehensive and systematic summary of the current legislation on cross-border shipments of waste in Czech Republic and an explanation of its individual institutes and regimes based primarily on Regulation No. 1013/2006 and Act No. 185/2001 Coll., on waste. The first chapter is dedicated to the historical development of regulation at the international level, where the Basel Convention and OECD Decision on the Control of Transboundary Movements of Waste Destined for Recovery Operations are discussed in more detail, as well as the historical development of regulation at the European and national levels. The second and third chapters are dedicated to the current legislation, which first defines the individual basic terms and entities used across the regulation and then analyzes the various types and regimes of transboundary shipments of waste. The fourth chapter deals with the function and position of administrative bodies involved in the control and supervision of transboundary shipments of waste. The last chapter deals with the illegal activity and legal liability arising from it in the cross-border movements of waste, there are also cases of...

First the corrugated shipping data will be broken down by industrial categories of destination and for each category will be made univariate SARIMA models. The estimates of disaggregated series are then aggregated to form the prediction of the total shipment of corrugated board. The prediction made from the aggregation of industry categories will be compared with a univariate SARIMA aggregate model, in order to ascertain which of the two methods results in a model with better accuracy. This comparison will be made based on the methodology developed by Diebold and Mariano / O presente trabalho visa comparar o poder preditivo das previsões feitas a partir de diferentes metodologias aplicadas para a série de expedição brasileira de papelão ondulado. Os dados de expedição de papelão ondulado serão decompostos pelas categorias industriais de destino das caixas e serão feitos modelos do tipo SARIMA univariados para cada setor. As previsões das séries desagregadas serão então agregadas, para compor a previsão da série total de expedição. A previsão feita a partir da somatória das categorias industriais será comparada com um SARIMA univariado da série agregada, a fim de verificar qual dos dois métodos resulta em um modelo com melhor acurácia. Essa comparação será feita a partir da metodologia desenvolvida por Diebold e Mariano (1995).

The diploma thesis deals with the processes associated with receiving and sending postal items of E.ON Czech Republic followed with the effective development of the life cycle of documents with use of the digitization and data mining. The aim is to develop the project "Electronic Registry", which can be implemented into current information systems of the company and which will contribute to the optimization of processes of the registry. To achieve this objective it was developed an extensive analysis of the current state of registry and records management system in E.ON Czech Republic. Based on analysis it was proposed a specific solution for improvement. The first part deals with the analysis of current legislative requirements and theoretical analysis of the document lifecycle, which is demonstrated on the example of E.ON Czech Republic in the second part of the thesis. In the second part there is the introduction of company E.ON Czech Republic, which is followed by description of the current state of registry and processes in relation to the rece-iving of postal items. In the analysis of the current situation there are identified issues that arise when receiving and processing postal items to the registry. To the identified problems are offered individual solutions, which are elaborated in the overall solution in the final part of the thesis. The last part is a custom suggestion of optimization of existing processes by using of digi-tizing paper documents and data mining for automatic sorting, which helps to streamline existing processes. This section describes specific solution that is introduced into the E.ON Czech Republic. The solution system provides a single place for the digitization of docu-ments received and their subsequent management.
