Dear Friends,
For a long duration of Project , we should perfom some activities which can start at data date but compeletion of these activies at the start of Projct is useless let me give an example;
Around 3 years later we should paint the building and before start the painting we should supply the paint and other necessary consumable , we can supply the material at project and tomorrow but it's useless and should put in the stock till three years later.
I need to know the correct relationship between painting and supply related materials. somebody told me introduce constraint activities before painting and somebody else mentioned you can use the negative lags with FS relations but both of these solutions end of months and during Project Reschedule made us problems becuase we have many relations like above activities.
My main question is how can define relationship between necessary material for opertional activities in case of provision of mterial can be finished in the short peroid (for example 60 days)
Thanks for your guidness
Hamid
