                                       Project Management
                                       With the solution design agreed, Total Logistics acted as the project 'Engineer', a role with
                                       officially defined responsibilities for managing the tender process. In this instance, Total
                                       Logistics was responsible for the procurement of all internal equipment required for the
                                       warehouse: detailed specifications went out to 26 companies for tender, managed through
                                       a number of short-listing stages before final selection took place. Simultaneously, Premier
                                       Farnell reviewed its WMS strategy with Total Logistics. Total Logistics were retained to
                                       provide full support during implementation, with a high level of responsibility for solution
                                       testing and delivery, including managing all supplier contracts.

                                       As  the extent  of  the  global  economic  downturn  in  2001  became  apparent,  the  full
                                       implementation of the project was postponed for one year. However, the costs of fulfilling
                                       European orders from Leeds were still high. In response, Total Logistics designed a smaller
                                       manual intermediate solution that could rapidly deliver important parts of the overall
                                       cost reduction with minimal capital investment.
                                       Total Logistics  knew that to derive maximum benefit from the interim solution,  work
                                       content had to be optimised.  The maximum number of  orders was  profiled with  the
                                       minimum number of lines. This identified the SKUs that could be positioned in Liege to
                                       give the lowest start-up and operational costs plus the greatest savings on shipping.

                                       Planning Contingencies
                                       The data was re-modelled but the original solution had been designed with  sufficient
                                       flexibility to accommodate the majority of range and volume changes. The interim solution
                                       could therefore be a scalable subset of the final design.
                                       The interim Liege solution went live in September 2002 and is delivering the planned cost
                                       reductions. It features a  19,000 sq  m  greenfield  warehouse in  two sections  (initially
                                       15,000 sqm followed by an additional 4,000 sq m) with a clear height of 10m and a usable
                                       height of 8.5m to accommodate  sprinklers. There are 24 conveyorised picking  zones
                                       covering  around  20,000 shelf  locations.  Products  are  stored  in  four  tote  sizes,  in
                                       manufacturers' containers or as free stock (for larger items) on shelving.
                                       All picking and stock movements are confirmed with wrist mounted RDTs feeding into
                                       the network of Dell PCs; scanning of barcodes is done via finger-mounted scanners and
                                       label printing via belt-mounted printers. Improved batching and picking techniques have
                                       generated substantial improvements  in picking productivity, saving time and  money.
                                       The conveyor servicing the picking zones is self-routing and able to handle more than
                                       1,000 orders per  hour. The design incorporates routing flexibility and fault  tolerance,
                                       allowing continued operation in the event of breakdown.
                                       The picking process includes an inspection area, a consolidation area and picking spurs.
                                       The consolidation  area is  automatically routed if there  is more  than one  tote and  the
                                       picking spurs have semi-automatic case-sealers.
                                       The interim design has three zones of bulk storage with 3,000 pallet locations, 6,000 shelf
                                       locations and  a reserve of  1,600 pallet  locations. All  pallet  racking is  adjustable  and
                                       fireprotected. About 40% of the storage area is static protected with conductive storage
                                       bins and totes and special earth conductive flooring.
                                                                                                           Contd...
