Frepple Description
Frepple is a Free Production Planning Library. Frepple is a Free Production Planning Library.Plenty of planning tools are available for various production problems, different subprocess, different solver techniques.... A bit suprising, no proper solutions exist in the open source domain. Users often are left with expensive and inflexible tools and resort to spreadsheets to meet their needs.This project aims at building an open source lightweight framework that easily and quickly delivers a solution for production planning problems. The initial focus is on small to medium sized master planning problems for the discrete manufacturing industry.For the developer community, the project is also trying to establish a common ground framework for planning applications. Rather than building the basic building blocks (e.g. item, buffer, bill of material, ...) from scratch over and over again, developers can leverage a proven framework to extend with their own extension modules.Here are some key features of "Frepple":· Modeling and solving framework for discrete manufacturing environments.Key modeling constructs are:· Item· Buffer· Resource· Operation· DemandSee here for a short domain model (requires Acrobat Reader).A complete class diagram and API reference are available to developers.· Heuristic, "MRP-like" solving algorithm respecting capacity, material and leadtime constraints.· XML-based data input and output.· Extensible and customizable architecture.New modeling constructs and solving algorithms can be developed in C++ and loaded as a plugin module.· The browser-based user interface and underlying database schema are based on the powerful Django framework.Both can very easily be extended and customized.· Embeds Python as scripting language.Allows for flexible and easy integration and customization.· Frepple comes as a 'library' developed in C++.It has no graphical user interface as such and requires to be deployed in a 'application'.Different applications are envisioned: · Standalone application for use at the command line· Microsoft Excel frontend· Accessable from programming languages such as java, python, perl or visual basic · Can be linked into your own C or C++ application· Apache module for browser based user interface and network based access· Supported on 32-bit linux and Windows environments, with Linux being the primary development platform.Porting to other platforms is discussed under the developer section of the documentation.· Licenced under the GNU lesser general public license.Learn here how this license protects my and your work.· To finish, a pretty bold statementFrepple will be the world's first true open source advanced planning system.What's New in This Release:· A security fix was released for the Django framework used in the user interface, resolving a cross-site scripting bug. What's New in This Release: · Better user interface: Improved editing, filtering and scrolling · Forecast module now includes timeseries analysis algorithms to predict the future demand · Big enhancements to the Python interface: Python is not an optional module any more, but part of the core · Corrections to the package layout to follow the common practice on Linux distirbutions · Various bug fixes · Upgrade to new versions of the third-party components: django 1.0.2, xerces-c 2.8, ...
