A complex project, as well as in the construction industry, requires the engagement of more categories of resources of type Work, uses many resources of type Material ad need sufficient financial resources regarding payment of costs. Purchases characterize materials during the project, consumptions, and inventories. By analogy can be observed the formation of the budget during the project: inflow of money, payment of costs and liquidity. The paper was exposed to the planning of Material resources and at the same time liquidity planning of the project with available Work resources. It is defined a general mathematical model to minimize the duration of the project and pointed out that there are four basic variants of the problem. This paper will propose the appropriate algorithms that generate solutions. Considering a hypothetical project, we will present the illustrative examples.
