Integrated Scheduling and Information Support System for Transit Maintenance Departments

Lopez Alvarado, Paula Andrea 25 March 2005 (has links)
The projected increase of population in the United States and particularly in the state of Florida shows a clear need of improvement in mass transportation systems. To provide outstanding service to rides, well maintained fleet that ensures safety for riders and other people on the streets is imperative. This research presents an information support system that assists maintenance managers to review and analyze data and evaluate alternatives in order to make better decisions that maximize efficiency in operations at transportation organizations. A system that consists of a mathematical scheduling model that interacts with a forecasting model and repair time standards has been designed to allocate resources in maintenance departments. The output from the mathematical models provides the data required for the database to work. Although the literature presents several studies in the field of maintenance scheduling and time standards, it stops short in combining these approaches. In this research, mathematical methods are used to forecast repair jobs occurrence to react to increments in service demand. Furthermore, an integer programming scheduling model that uses the data from both, the developed time standards and the forecasting model is presented. The information resulting from the models is entered to a database to create the information support system for transit organizations. The database gives the scenarios that facilitate optimizing the allocation of jobs in the facility and determines the best workforce for each required task. Information was obtained from observations at three transit facilities in the Central Florida area; the model developed is tested in their scenario by using historical data of the maintenance jobs currently performed.

Optimalizace logistických činností při expedici v elektrotechnické výrobě / Logistic process optimization in expedition of electrical enterprise

Reboková, Lenka January 2008 (has links)
Logistics as a process of planning, realization and controlling of effective and powerful workflow and commodities warehousing, services and related information with the goal of costumers satisfaction, became highly important and inseparable part of every company. The essential part of the planning process is an analysis of the current company situation, which tries to find all the limiting factors, and which serves as a basis for the process of making a company more effective. This diploma thesis analyses the current state of the expedition division of the ModusLink Czech Republic s.r.o. company – it analyses all its working operations in detail and using chronometrical analysis method evaluates division‘s theoretical and feasible throughput capacity. The feasible throughput capacity is then confronted with division’s real throughput capacity achieved during the monitored months, and depending on the results of the comparison there are some conclusions and recommendations for future improvements mentioned.
