This paper presents an innovative approach towards the development of a green concrete. The geopolymer is environmentally friendly construction/repairing material. In addition, glass fibers are helpful to influence strength properties and reduce hair line cracks bleeding in study based on use fly ash as partial replacement cement and, subsequently, its effect compressive split tensile manufactured after process geopolymerization between class F alkali activator fluid (sodium silicate sodium...
Today the internet has become primary source of communication among people because it holds limitless space and pool various web applications resources.The allows us to communicate in a fraction second with another who is sitting other part world.At present, our daily life its usage increasing exponentially, therefore accumulates number on basis Web podium.Most exist few weaknesses that give room several bad buys (hackers) interrupt weak code applications.Recently, SQL Injection, Cross Site...
Modeling of train operations is helpful to plan railway corridor activities and optimize the use resources. This paper models scheduling problem a single line network with main concern minimize total operational cost delays relation position sidings. Problem modeled as jobshop solved using Branch Bound (B&B) technique. Sensitivity analysis done changing number sidings trains. Approach used here has quantified relatedness between conflict delays. Objective was show impact on timetable....
It is a common practice to improve the punctuality of railway service by addition time margins during planning process timetable. Due capacity constraints network, limited amount can be inserted. The paper presents model and heuristic technique find better position for (headway buffers running supplements) in train aim reallocating adjust an existing timetable minimize sum delays at event operational disturbances. consists two basic parts. Firstly, treats as Directed Arc Graph (DAG) with...
The traveling salesman problem (TSP) plays an important role in the field of transportation and logistics. While most studies focus on developing algorithms to find shortest path explore average length paths, degree which deviates from its mean has not been studied. study deviation is because it implications for travel time reliability. Previous have used various indicators measure this deviation, mainly including standard quantiles, buffer index (BTI). Therefore, aims develop empirical...
This paper provides the survey of heuristics solution approaches for traveling salesman problem (TSP). TSP is easy to understand, however, it very difficult solve. Due complexity involved with exact hard solve within feasible time. That’s why different are generally applied TSP. Heuristics presented here detailed algorithms. At end, comparison among selected shows efficiency in terms quality and time consumed

Demand Responsive Connector (DRC) is a type of flexible transit service that connects the residents an area to transportation hub. Previous studies on DRC have optimized design parameters with objective minimize passengers' travel time. However, cost and profit were neglected, making it difficult for operators use optimization method design. In order fill this gap, study explores way optimize maximize considering under elastic demand. Rectangular case one vehicle are used in study....
This paper provides an overview of Pakistan Railways scheduling and rescheduling. First all, is introduced with its brief history importance in this country. Assets network passengers freight using are given. Current hope less situation leading to privatization system as well promoting short distance traveler use road Government efforts retain also presented. Train being done manually, based on manual time graph preparation resolution conflicts manager's experience ability. In Real-time...
The Hong Kong-Zhuhai-Macao Bridge (HZMB) is an important transportation facility connecting Kong, Zhuhai, and Macao. Thus, analyzing the characteristics of cross-border behavior becomes crucial for enhancing smart travel experience HZMB. Discrete choice models (e.g., logit models) are commonly used to describe mode behavior. Multinomial (MNL) subjected independence irrelevant alternatives (IIA) assumption. Nested (NL) model does not consider heterogeneity individuals. Mixed (MXL) can...
Abstract Introduction. Station route allocation plan is an important extension of the train running diagram and both are closely intertwined so overall research on synergetic preparation method more beneficial in improving quality providing better service for passengers. Therefore, topic has practical significance. Methodology. Based extensive literatures, this paper studies station detail analyses their association a theoretical basis method. Results . This work introduces synergetic,...
Shared bikes can help cities achieve carbon neutrality goals. Cleaning and disinfection are vital procedures of the maintenance shared bikes, especially during COVID-19 pandemic because could be a transmission intermediary viruses.

By regarding staff as traveling salesmen, formulated extension Multidepot Multiple Traveling Salesman Problem (MDMTSP). objective...
This paper focuses on a single-track train scheduling problem. The problem formulation is based job-shop structure, which considers trains (as tasks) that are assigned to tracks and stations machines). objective minimize total travel time each has prespecified departure travelling route. trains' running times at segments taken as constant. Branch bound search technique presented with priority rules obtain optimized feasible schedule. More specifically, best cost, early start, finish, minimum...
