this paper describes a simple, physically-based conceptual model utilizing watershed drainage characteristics for rainfall-runoff simulation. this conceptual physiographic model is essentially based on the work of najafi (2003), which has led to a model compris-ing the main tributary subwatersheds and a single main channel subwatershed. the ki-nematic wave (kw) theory is used to describe flow o...

This research is a survey and exploratory study to present a conceptual model for the sustainable development of Iran based on social entrepreneurship. Its approach for conceptual modeling is based on Path Analysis through Multiple Regression Method. The study has benefited from five questionnaires (four for the Delphi Method’s rounds and another for the conceptual modeling itself). The statist...

zinc is the first modelling language which supports solver and technique independence. this means that a high level conceptual model can be automatically mapped into an appropriate low level design model for a specific solver or technique. to date, zinc uses three different techniques to solve a model: constraint programming (cp), local search (ls), and mixed integer programming (mip). in this ...
