In this paper two new Mixed-integer linear programming models for fuel based vehicle routing problem are introduced. By considering the refueling accessibility in customer nodes, these models are formulated as a Fossil Fuel Capacitated Vehicle Routing Problem with Time Windows and the Green Bi-fuel VRPTW. A fuel delivery routing problem is a real world application of these models. Environmental...

This paper proposes an integrated network design model for a post-distribution cross-docking strategy, comprising multi product production facilities with shared production resources, capacitated cross docks with setup cost and customer zones with time windows constraints. The model is dynamic in terms of time-varying uncertain demands, whereas uncertainty is expressed with scenario approach an...

The multi-depot pickup and delivery problem with heterogeneous fleet and soft time windows (MDPDPHSTW) requires to find a minimum cost routing for a fleet vehicles with different capacities and based at different depots, satisfying a given set of customers. A customer request is associated with two locations: a source where a certain demand must be picked up and a destination where this demand ...

In the emerging competitive and technological driven banking era, banks have to strive hard for retaining and enlarging their customer base. Electronic customer relationship management (E-CRM) is the combination of traditional CRM with the e-business applications marketplace. An E-CRM system provides financial institutions with the opportunity to establish individual and need oriented customer ...

To be successful, organizations must look into the needs and wants of their customers. That is the reason why many researchers and academicians have continuously emphasized on the importance of customer satisfaction, loyalty and retention. Customer satisfaction is important because many researches have shown that customer satisfaction has a positive effect on an organisation’s profitability. Du...

This paper describes a heuristic to build piecewise linear statistical models with multivariate thresholds, based on a Greedy Randomized Adaptive Search Procedure (GRASP). GRASP is an iterative randomized sampling technique that has been shown to quickly produce good quality solutions for a wide variety of optimization problems. In this paper we describe a GRASP to sequentially split an n-dimen...

This study examines some major variables moderating the relationships of service quality, customer satisfaction, and customer loyalty in mobile phone services. The study employed statistical analyses, such as reliability analysis, factor analysis, and hierarchical regression analysis. The results of the study reveal that service quality and customer satisfaction positively affect customer loyal...
