The paper presents a framework for numerical simulation that allows you to ensure saving of resources due to the numerical selection of the optimal size and temperatures in the preparation of bimetallic castings. Modeling obtained boundary and initial conditions at which the metal parts submelting first layer in the contact area with the second layer and is saved in the unmelted state of the first layer with a thickness of 1.5-2 mm, which is in contact with the mold.
The work deals with problems of budgeting in the context of the economic crisis. Classification of the budget is considered and their characteristics are given. For each budget, it has proposed a system of indicators. Recommendations were made for the algorithm for calculating these indicators. Particular attention is given to the cost optimization.
