If this was airfreight or sea freight, they would use unitised containers. Ideally each originating company would load its own container, seal it and drop it off at the transhipment point. The entire container would be loaded onto the local delivery vehicle at the consolidation centre. One container would go to each store. Supplier companies could choose the size of their containers – varying from small to quite large - but, like sea containers in miniature, (or the A1,A2, A3, A4 sizes of paper system), the units should be of compatible dimensions to allow stacking and multiplying. This will lead to some space being wasted and some 'air' being shipped by each supplier company. But the alternative is hugely varying parcel sizes being stacked in the back of lorries, which will lead to wasted space anyway. Unitisation allows vehicles to be loaded more easily in order of drop-off. There is much less chance of individual boxes being left behind on the vehicle. If the charge was made according to the size of unitised container, then the supplier company can make instant decisions about which is the most cost-effective size of unit to send to any store for any given order. If they don't have enough small unit containers, they will soon get them if there is this financial incentive. The market will then regulate the consignment size and this will control wasted space. This is coincidentally an argument for NOT charging according the unit's 'metric' (i.e. combination of weight x dimensions, roughly equal to mass). Standard unitisation would allow the local delivery vehicle to be equipped with suitable handling systems to deal with each size of unit or multiples thereof (like a container-handler at a major port, although in miniature). This reduces the manual handling risk and need to control box weights. (Unit weights would still need to be known to permit vehicle loading within axle weight limits - like a ramp agent planning the load disposition for an aircraft.) When I worked at FedEx they used to offer a big discount for standard-sized packages. Unusual shaped packages could be taken, but attracted a premium charge. If there was some product that really can't be shipped in standard unitainers, then maybe that supplier would be better off sending their own vehicles into Brum anyway - on the empty streets? In this instance, each unitised container would be treated exactly like a parcel at a parcel sorting hub. Each unit is bar-coded (like sea containers, each unitainer can have its own number, allocated to the supplier company - or the leasing company). The software for running parcel-sorting hubs is well established and getting cheaper. You can to some extent buy it 'off the shelf'. It would be so much simpler than trying to create a new software package that is full of glitches and cost. As Bill Acres will know, the existing system that FedEx was using at its main hub in Memphis, dealing with many tens of millions of parcels from all over the world in a very short time span, would be much larger than anything Birmingham retail suppliers could generate. Each node (i.e. shipping point at the end of a spoke - e.g. London) would be roughly analogous to a supplier company. Each supplier can be readily billed for the number of parcels and their total metric (size/weight) to have passed through the central hub. One argument against having company-dedicated unitainers is that they have to be returned to the supplier, normally empty. However in Laura Ashley Logistics, we were legally obliged to recover all recyclable materials from our shops to our distribution centres (clothes plastic wrappers, hangars, cardboard, waste paper, etc. etc.) where we sorted, cleaned and compressed it and sold it for recycling, achieving a much higher financial return than simply paying a local contractor to take it all away from each shop. Possibly ordinary refuse could be treated the same way, reducing the costs of waste disposal for chains of stores. This would reduce the need for the city council to send its own refuse vehicles into town and reduce loaded journeys to landfill/incineration. Backfilled unitainers can also be used to return all sorts of other materials such as obsolete or end of line stock, company mail, etc. For larger products being moved between sites within Birmingham, the transhipment centre could work on a hub-and-spoke system. Finally, unitainers can be easily fitted with trackers and the sealing system improves security between supplier and shop. The trackers serve a double purpose; allowing the freight forwarder (and by extension the supplier) to know where the container is at any one time, and also making it very difficult to steal the whole unitainer. While the use of trams is a worthy consideration, I just can't see it working. Anything over 20kgs will need two people to collect it from the drop-off point, and how on earth one manages the infrastructure of drop-off points at tram stops is a nightmare. All shops will have different delivery points; few will want to take deliveries through their front doors if they have a choice. Surely the whole point of this scheme is that all suppliers delivering to any one particular shop have their loads consolidated in order that each shop only gets one delivery - probably at crack of dawn - right to their back door, from all their suppliers. This dramatically reduces the number of vehicle fleets operating in the centre, but will not necessarily decrease the number of vehicles significantly - any reduction in vehicle KM will only be of the order of about 20 - 30%. However vehicle size and utilisation will increase commensurately and the streets can be made more pedestrian-friendly during the day. There is a corollary: in-store staff costs reduce dramatically. For smaller shops, the goods receiving staff only have to be there for one delivery and its time can be reasonably predicted. It is possible that the freight forwarder could let the store staff know when their containers were due - especially if there were multiple deliveries during the course of the day - much like the timing of buses on real-time display systems. (You’re going to get 3 together...!) Presumably the local delivery vehicles can be of differing sizes according to the type of product and size of unitainers they transport. Some of these will surely be hybrid fuel vehicles and environmentally friendly.
Well, that’s my ha'penny.
