The objective of this paper is to develop scheduling scheme products during shortages, considering supply. For purpose, bi-objective mixed-integer programming model proposed, one minimises maximum shortage hospitals as well other latest arrival time. To solve model, ...

To design a bioethanol supply chain, along with the transportation and operational costs, it is vital to consider more factors categorized into three sustainability pillars (i.e. economy, social environment).

Multi-objective equilibrium models of traffic assignment state that users of road networks travel on routes that are efficient with respect to several objectives, such as travel time and toll. This concept provides a general framework for modelling traffic flow in tolled road networks. We present the concept of time surplus maximisation as a way of handling user preferences. Given a toll, users...
