## I forgot this...my decision...

I forgot this...my decision variable is Production[i,j,t]...This matrix is the solution for the problem.

## Global Optimization...

Doug:

The idea that you tell me is like a Dynamic Programming?

If that is the idea, i´m sorry but i nedd to do this by NLP.

But, can you tell me how to write yor idea in Maple please, the vector of matrices.

Thanks again.

## OK....

Doug...I'm trying to raise the constraints for a capacity production using NLP.

The idea is to make a model for productivity. The model have to give me PDCX and PDCY as answers.

Given Data:

V[i,t]: sales for product i for day t.

M[i]: minimum monthly production of product i.

SI[i]: initial stock of product i

PDX[i,j]: productivity of product j coming from producing product j on productive line X.

PDY[i,j]: productivity of product j coming from producing product j on productive line Y.

Decision Variables:

PDCX[i,j,t]: boolean. 1 if the product i is produced coming from product j the day t. 0 in another case. In production line X.

PDCY[i,j,t]:boolean. 1 if the product i is produced coming from product j the day t. 0 in another case. In production line Y.

The problem have 24 days, 10 different products in line X and 8 different products in line Y.

Productivity is product to product. Is a matrix where the diagonal shows the maximum values.

I need to write with Maple PDCX and PDCY for making the constraints.

Sorry for my english.I'm not american or english speaking.

## Hypermatrix...

Another question...

It is possible to read the data for the matrix from a text or an excel file.

Thanks again.

## Hypermatrix...

I want an  m by n by k Array...

I need this matrix for an objective function.

I need to multiply this matrix with another one that is bidimensional to generate constraints to my problem.

Thanks.
