QUESTION THREE a) FRA plans to set up more satellite depots for the small scale farmers in Lusaka, Central, Southern and Copperbelt Province. The move is aimed at easing transportation costs small scale farmers incur during harvesting period. Six satellite warehouse locations have been identified in the respective provinces These sites, and the distances (in km) between them are listed on the table below. FRA through partnering with RDA wants to minimize the kilometers of roadway required to provide the desired accessibility to these satellite warehouse depots To LSK CHI | KBW CHO | NOL | KTW From Lusaka (LSK) 370 350 Chisamba (CHI) 250 400 300 290 350 | 300 | 200 T | 300 | 210 | 250 | 370 250 300 350 400 290 | Kabwe (KBW) Choma (CHO) Ndola (NDL) Kitwe (KTW) | - 350 200 350 - 250 200 250 Determine how roads should be built to achieve this objective and the minimum distance [6 Marks Discuss any five (5) common roles of warehouses [5 Marks] ii. b) Kaminamisa Breweries are a decade old opaque beer distribution company. Due to some challenges in distribution, Kaminamisa wants to build a warehouse on one of its sites. It operates in a region with seven possible sites as shown in the diagram below. The underlined figures represents the fixed cost ($'000) of setting up a warehouse whereas the figures in boxes are the demand ('000 litres). The rest of the figures represent the distance (Km). The organization seeks to minimize the cost of distribution which is the total fixed cost of opening the warehouse plus variable cost of distributing the goods. The variable costs are $4 per unit
