sentences:  Thus the 'market location' can be used as a sort of isolator between actual demand and how supply would like demand to be, an isolator between batch demand spikes and the up upstream supply process.For example, if the market were positioned at the loading bay, then it will receive 'spikes' of demand whenever a truck comes in to be loaded.Since, in general, one knows in advance when trucks will arrive and what they will require to be loaded onto them, it is possible to spread that demand spike over a chosen period before the truck actually arrives.
