Market action

Post by paulvbaal » Thu Nov 23, 2017 3:40 pm

Hi,

I am stuck trying to figure out how to get a market action to work.

I am basically trying to match supply and demand bids for a certain good, I have three entity types: Market, Supply, and Demand. Supply and demand entities have a auxiliaries "amount" and "quantity", denoting respectively the requested amount and the requested priority. The singular Market entity is the owner of the action and determines when to clear the market. However, when creating the action, I do not have access to the auxiliaries of refSupply or refDemand, even if the Collection in the market operator is set to respectively Supply[] or Demand[]. In contrast, with the Allocate action, set up in exactly the same way, I can access those, and it functions.

I attach my model to show the problem.

Sorry for the mistake, it should read that both Supply and Demand entities have an "amount" and "price" auxiliary, denoting respectively their amount and priority for the market clearing.
