Good day. 

I recently constructed a Maple model using an LPSolve routine to solve for a classic factory (Operations Research) assignment problem. Basically, this involves 4 factories that, in any combination, can supply goods and fulfil demand to 10 customers. If any given factory is activated, the model determines what factory should supply what customer so that the weighted-distance is minimized.

However, in addtion to this - I would like to know the quantity of items that each factory supplies to each of their respective customers and I would like to verify that the quantity demanded by each customer is fulfilled. 

I was hoping that somebody could guide me on how to do this. Any suggestions would be most welcomed.

The model is attached.

Good day.

I am working on a time series problem that uses 107 data sets (historic) and I wish to obtain a forecast for the next successive 12 events. I have obtained the time series plot for the predicted values and the associated dates separately (see attached), however - I am looking to get the solution in a more user-friendly format and was hoping someone could help me out.

Can someone tell me how to 

1. Express the data values only as whole number values (decimal-free)

2. Construct a table of data values and dates for the average forecast as well as the 2nd and 98th percentile forecasts?

Thanks for reading!

Good day! 

I have been wrestling with what appears to be a simple problem, but with no success and so, I thought I would reach out for support. 

Consider a two-dimensional strip of any given width, x, and depth, y.

I wish to maximize the quantity of strips that can fit inside a larger two-dimensional surface of any given width, X, and depth, Y. Overhanging is not permitted and all smaller strips must lie within the interior of the larger surface. 

I'm looking for a solution method that can calculate the best configuration necessary to fit the maximum number of smaller strips in the interior of the larger rectangle. Can someone suggest a way (if possible) to solve for this?

Thanks for reading.

Good day! 

I attempted to download the geocoding package for Maple and I cannot get it to work. Executing the worksheet produces no results.

I am using Maple 2022. 

Can anyone shed some light on this please?

Good day. 

I have been looking into the time series features in Maple and was eager to apply the models to one specific example containing 47 data points (attached).

When I run the ESM routine, Maple provides a forecast based on a (A,N,N) configuration. You will notice that the forecast for the following 12 data points is a constant value. I have also noticed this for several other data set examples and I would have expected the predictions to vary across the next 12 data points.

Does the (A,N,N) configuration in Maple automatically provide an optimal forecast and can anyone advise me on how to specify all possible combinations of (error, trend, season) models?

Thanks you for reading.
