Solve linear programming problems
Linear Program Solver (LiPS) is an optimization package oriented on solving linear, integer and goal programming problems. The main features of LiPS are: ● LiPS is based on the efficient implementation of the modified simplex method that solves large scale problems. ● LiPS provides not just an answer, but a detailed solution process as a sequence of simplex tables, so you can use it for studying/teaching linear programming. ● LiPS gives sensitivity analysis procedures, which allow us to study the behaviour of the model when you change its parameters, including: analysis of changes in the right sides of constraints, analysis of changes in the coefficients of the objective function, analysis of changes in the column/row of the technology matrix. Such information may be extremely useful for the practical application of LP Models. ● LiPS provides methods of goal programming, including lexicographic and weighted GP methods, which are oriented on multi-objective optimisation.
Reason is rare. The reasoning behind day to day decisions and important issues are often unknown, unadmitted or misunderstood.Argumentative allows you to express an argument’s structure in a visual form which is simpler to understand.

Simple, pragmatic enterprise architecture - for system-thinkers
TRAK is a general systems-thinkers'/system-centric enterprise architecture framework. It is simple, user-friendly, pragmatic and not limited to IT. TRAK has won an INCOSE award and is also a finalist in the 2011 IET innovation awards. TRAK allows you to describe a system, its parts (which can include people, software, other systems and physical things) and how it relates to the residual world. It covers everything from the enterprise, concept, procurement of the solution, the introduction or withdrawal of the system from service to its assurance. It allows threats,risks and mitigation to be linked to the design. TRAK is a derivative of MODAF but is based on ISO/IEC 42010 - the international standard for architecture description. There is a minimal process in which the architect selects the viewpoints (specifications for views) that address the task sponsor's concerns. It has rules that ensure that the description is consistent and also readable by the non technical audience. You

Gestion Revit permite crear presupuestos desde un modelo BIM
Gestion Revit es una aplicación de MS Access que permite crear cómputos y presupuestos. Se caracteriza por extraer toda la información desde un modelo BIM creado en AutoDesk Revit y confeccionar el presupuesto de manera automática. Se conecta con MS Project y permite crear un Diagrama de Gantt de manera sencilla y rápida. Con el Modelo BIM y el Diagrama de Gantt es posible crear simulaciones constructivas BIM5D. Gestión Revit extrae el cómputo métrico de un modelo BIM de la obra, lo que garantiza mayor precisión en las mediciones, reduciendo los errores por olvidos o modificaciones al proyecto. Cuanto mayor sea la precisión del modelo BIM, mayor será la precisión del cómputo métrico resultante. Instrucciones: 1) Descargue "GR-2013_Instalador.exe". Instale el software. Este es el programa BASE. 2) Descargue "Actualizar_a_GR-2015.exe". Instale el software. Esta es una actualización, que hace compatible a Gestión Revit con AutoDesk Revit 2014 y 2015.
Zenta Es No Tan Archi
Zenta is a free, open source, cross-platform tool and editor to create models along with their metamodels. Zenta is forked from Archi, which is an implementation for the Archimate methodology. Archimate is a closed standard of the Open Group. Yeah! This created a situation where in theory you could use a software with an expressed open source licence only with permission. And anyway, you might want to use other - or more - metamodels. Zenta is targeted toward all levels of Architects and Modellers. It is intended to provide a low cost to entry (i.e. free) solution to users who may be making their first steps in the architecture modelling or who are looking for a cross-platform modelling tool for their company or institution.

Excel function for multi-criteria selection problems
SCOREMATH implements the simple-yet-ingenious weighted linear model for multi-criteria selection problems described in Ng, Wan Lung. "An efficient and simple model for multiple criteria supplier selection problem." European Journal of Operational Research 186, no. 3 (2008): 1059-1067. "There are many real situations where the decision makers are able to tell the criteria importance ranking (although they cannot tell the exact values of weights). The decision makers may not have enough knowledge to assign exact weight values but they can rank the importance by their expertise or experience. [...] [Our model] requires no pre-defined weight values. At the same time, our model can incorporate some user control by ranking of relative importance of the criteria. [...] decision makers only rank the relative importance of criteria, rather than specifying the degree of relativity. [...] [our model] does not require users with any optimization background."

A free, easy-to-use and user-friendly Java-based UML editor.
Firefly UML is a 100% pure Java application designed to create and edit UML conform diagrams. With class diagrams, sequence and instance diagrams, Firefly UML provides a solid selection from the vast range of existing UML diagram types. Firefly UML is really easy to learn as it provides you multiple ways of access to the same function - be it mouse action, hotkey, context menu or toolbar icon. And the best thing is: once you have learned how to handle one type of diagram, you also have learned how to deal with the other diagram types, because they all follow the exactly same user interaction patterns. Besides being user-friendly, Firefly also offers powerful features which other free editors usually do not. For example, you can import your existing Java project into Firefly and generate nice-looking class diagrams within a matter of minutes. You can also go the other way around and export your model as skeleton Java code.

Lua interpreter embedded into an Excel XLL
LuaXLL is a lightweight Lua interpreter built into a Excel XLL. The XLL has extensions built into it which allow new Excel functions to be defined in a Lua script and exposed to the main application with the XLL marshalling data across the environments. Its primary use is for rapid modelling and development. And it could also serve as an interface to more advanced models built in C. It has built-in support for ODBC databases (via LuaSQL) and some generic modeling functions (added as I need them). The entire XLL is currently less than 600KB.

Queue network modelization tool
Ceci est le projet réalisé à la session d’hiver 2014 par l’équipe Expresso. L’équipe était composée de : Philippe Olivier, François Lemonnier-Lalonde, Dominique Tremblay et François Moreau. Le projet a été réalisé pour le cours de Génie logiciel orienté objet, donné par M. Jonathan Gaudreault à l'Université Laval. Le projet consistait à développer un logiciel de modélisation de réseau de files d’attente, aussi appelé un réseau de Jackson. Chaque nœud du réspeau représente une station de traitement et chaque arc orienté représente un chemin possible d’une station à une autre. Le réseau possède toujours un point d’arrivée et de sortie. Un tel réseau peut, par exemple, représenter la zone de sécurité d’un aéroport, l’urgence d’un hôpital ou une chaîne de montage.

Determining the power output of a PV array is not a precise exercise
The power produced by a PV array depends on characteristics of the PV modules used and the instantaneous climatologically conditions. For most field testing, the measurable quantities are irradiance and temperature. Power is an instantaneous value; the PV array produces so many Watts (or kilowatts) of power at a specific time depending on existing conditions. Power output will change continuously throughout the day. Energy includes a time factor and is measured in Watt-hours or kilowatt-hours (kwH).
