Production Mix Model Excel
$20 - Bizpep

This model calculates the Product or Service Mix that maximizes overall profit considering available resources. It will identify the mix (number) of each Production Item to produce and any remaining resource. Up to six unique Production Items can be handled with ten specific resource inputs. Production Items can be considered as the output of any process including manufactured items and the provision of services. Resources are anything that is needed to produce or provide the Production Item. This may include materials, labor, machine time, floor space, transportation services etc. The model applies Linear Programming to identify the optimum result. It considers the resource demand, profit contribution and any minimum or maximum production requirements for each Production Item. By using the Solver Add-in included with Microsoft Excel the optimum solution is identified and can then be manually adjusted to test alternative scenarios. Operation is fully automated with tabular inputs and outputs. No knowledge of Linear Programming or Excel is required for use.

Cut 1D X
$35 - Optimal Programs

Cut 1D X is an Automation Component used for obtaining optimal cutting designs of one dimensional pieces which may have angles different of 90 degrees at their extremities. Cut 1D X can be used for cutting linear pieces such as bars, pipes, tubes, steel bars, or any other material used by industrial applications. Cut 1D X can be used within any programming enviroment such as Delphi, C++Builder, Visual Basic, Visual C++ etc

Features:

Pieces to be cut can have angles different of 90 degrees at their extremities. A lot of material can be saved by properly matching 2 pieces having sharp extremities. For instance, if you match 2 pieces having 45 degrees at their extremities you will save as much as the height of the pieces.
Automatically compute the number of maximal repetitions for the current layout.
Compute the cutting order which is very important if the extremities have angles different of 90 degree. If all angles have 90 degrees the cutting order is not important.
Very fast algorithm (Solutions are obtained in seconds).
Compute the waste for the current piece.
Independent measurement metric.
Adjustable cutting blade thickness.
Adjustable optimization level.
Can be embedded within any language that supports automation (VB, Delphi, C++Builder, VC++, etc) and dynamic link library (dll).

RF21
$0 - Christoph Hohmann

RF21 for Windows is a scientific calculator, plotter, programming and numeric system in one. It allows for permanent installation of a user's own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago. Each function self-reassembles when its name is called, autonomously searching the libraries for all components needed.
Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including:
Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, n-dimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer.
Fast screenplots and an environment for designing printable plots, which may as well be exported to -.GIF and -.BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields.
Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see author's homepage for a systematic reference of these.
