In recent years, collaborative transportation and pooling have become urban logistics alternatives to classical urban consolidation centres, but remain in a developmental stage. This chapter proposes a framework for urban logistics pooling, strategic planning and ex-ante evaluation. First, the main concepts of logistics pooling and their applications to urban delivery services are presented. Then, an information systems-based framework for planning and evaluation is described, from which a set of indicators are identified. To illustrate this framework, a case study from a French urban logistics pooling system is proposed.

For this problem, we propose an implementation of the standard multi-objective evolutionary algorithm NSGA II. To improve its efficiency, two mechanisms
