have added another layer in this transportations network in-between the end customers and the
distribution centres: that of collection points in local shops. solve all 4 parts
(a) Give a generic formulation of a logistics cost minimisation LP problem for Amazon UK before the layer with the collection points was added, (b) gve a generic formulation of a logistics
cost minimisation LP problem for Amazon UK with the collection points, (c) expand the latter
so as to allow for transhipments in between the distributions centres and provide both a graphical network and an LP formulation, (d) Why did they decide to go for the introduction

of collection points and under what conditions is this a sensible move?
