Hello,
I am trying to model the following scenario, but with little luck. Maybe Rafael or Vladimir cand help me a bit.
Scenario:
01. Formwork for columns is rented, 1 set (column) = 1000 currency/30 days, 1 set = 25 currency/day.
02. Formwork for columns rent is a minimum of 30 days. After 30 days the rent becomes 25 currency/day. If the formwork is rented less than 30 days the rent is still 1000 currency.
03. Formwork should be delivered on site 1 day earlier than the first activity of Column formwork instalation.
04. Number of crews for cast in place columns is another variable for this scenario.
Purpose: I would like to run different scenarios to see which is the best reasonable solution depending on the number of crews and number of sets of Column formwork the company rents. Is it more advantageous to use 2 crews and 10 sets or 1 crew and 20 sets of column formwork.
Here is how I started:
01. 3 Phases of columns, each phase has 10 columns
02. 1 Phase for formwork delivery, return. Formwork delivery milestone, formwork return milestone. 30 days rent limit milestone, daily rate over 30 days hammock with 1 minute calendar and hourly cost.
03. Column curing and Column formwork removal have strict link.
04. Formwork delivery has all Column reinforcement FF(-1d). This is not correct but if I make all Column reinforcement activities as successors of the Formwork delivery with lag +1 day and set Formwork delivery to ALAP this will not work because Formwork delivery will not be schedules ALAP due to the fact that the 30 days rent limit activitity is scheduled ASAP.
05. There is a problem with the model in the scense that Formwork delivery takes place on the 17.03 but one Column formwork instalation activity start on the 16.03. This can be fixed by setting profiles.
06. I setup Formwork material consumption and revenue for Formwork Delivery, Formwork Return, Column formwork instalation and Column formwork removal.
