Um, Institute of World Economics and Informatics
Task 1
Solve graphically

Task 2
The company manufactures products A, using raw materials costs B. Cost matrix set A = {Aij}, the number of each type of raw material in the warehouse - Vj (shown right). Profits from the sale of units of product j-type specified below. How many of each type of product you need to make in order to maximize profits? Determine the value of raw materials and product profitability.

Activity 3
Solve the transport problem

Task 4
A = {Aij} - the matrix of direct material costs,
y - the vector of final output.
Required:
1). Build a table of input-output balance in value terms.
2). Find the change in gross output by increasing the final release of the first branch by 20%, the third - 25%, and constant release of the second end of the industry.

Task 5
There is evidence of the value of production (Q) for ten months, and the value of fixed assets (F) for the twelve months of the year.
1. Select a productive factor and signs. Perform graphical analysis of the data. Select the appropriate model, to make its specification.
2. Determine the OLS estimate model parameters, to find out their significance, as well as the equation altogether.
3. The method of linear extrapolation of the forecast period, value of production for November, December.
4. The method of correlation and regression analysis, as well as adaptive smoothing (by Brown) predict the value of production for November and December.
5. Analyze the results of forecasting
