The government-run command post in Tunis is staffed around the clock by military personnel, meteorologists and civilians. On the wall are maps, crisscrossed with brightly colors arrows that painstakingly track the fearsome path of the enemy. An alternative to the market system is administered control by some agency over all transactions. This agency will issue laws or commands as to how much each goods and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan drawn up by the government shows the amount of each commodity produced by the various firms and distributed to different households for consumption.
