Are PROPLAN and PROBID Resources similar?
While superficially similar (they both have codes, descriptions, costs, etc.) the resources used in PROPLAN and PROBID also differ in several respects. PROPLAN resources are Reusable (e.g. carpenters, bulldozers, power demand, systems analysts, office occupancy, batching capacity) or Consumable (e.g. bricks, concrete, cash, energy consumption, computer time.) PROPLAN resources also have an allocation mode. This may Daily usage, Fixed amount, or Start or End day. The allocation mode allows you to distinguish between resources whose consumption is dependent upon duration and those whose consumption is fixed. The latter can be allocated as total amounts in three different ways – as a “Fixed” allocation, which the program will evenly spread over the activity duration, or totally on the Start or End day. The default is by a Daily usage rate. This may be appropriate for labour, equipment and supervision if the work force is constant – and hence the total usage varies with task duration. This
