Optimising TransMilenio BRT system operation: a mathematical model

Simulation of beijing brT operation with random Departure Time

by xumei chen, lei yu, liu yu and jifu guo inTroducTion As an innovative public transport option, bus rapid transit (BRT) has been widely applied in recent years. Big cities in China are experiencing rapid motorization at an alarming rate. In such a situation, many cities in China have attempted to bring BRT into their transit systems to address urban transport problems. A wave of BRT planning ...

Solving a new mathematical model for cellular manufacturing system: A fuzzy goal programming approach

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

Development of a mathematical model to design an offshore wind and wave hybrid energy system

Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...

Mathematical Model and Solution Algorithm for Containership Operation/Maintenance Scheduling

This study considers the problem of determining operation and maintenance schedules for a containership equipped with components during its sailing according to a pre-determined navigation schedule. The operation schedule, which specifies work time of each component, determines the due-date of each maintenance activity, and the maintenance schedule specifies the actual start time of each mainte...
