The research design adopted to address this problem utilised mixed data collection methodologies. In order to determine what was happening in the industry as a whole, a specially designed survey was conducted utilising both web-based and traditional paper-based instruments. This provided valuable quantitative data about the rate of uptake, types of companies and so on. To complement this, a focus group of selected representatives within the industry was conducted to delve more deeply into motivations behind the decision to adopt the technology and the perceived benefits derived from it.

In this research, a bi-objective hybrid vehicle routing problem is presented and solved by considering alternative paths, various lengths and reliabilities. The first objective function minimizes overall system costs, fuel consumption, and greenhouse gas emissions, whereas the second objective function maximizes the reliability of the entire system with alternative paths and several reliabilities.
