Different aspects of software projects must be estimated among which time and effort are of significant importance to efficient project planning. Due to complexity of software projects and lack of information at the early stages of project, reliable effort estimation is a challenging issue. ...

PROJECT DYNAMICS AND EMERGENT COMPLEXITY Christopher M. Schlick Institute of Industrial Engineering and Ergonomics RWTH Aachen University ABSTRACT The present paper presents theoretical and empirical analyses of project dynamics and emergent complexity in new product development (NPD) projects subjected to the management concept of concurrent engineering. A model-driven approach was taken and a...

on time supply of materials in construction projects is very important. therefore, coordinating a project with key suppliers, while ensuring the timely supply of materials, make the minimum costs of project. one way to create this coordination is integrated inventory planning which has been accomplished in this study. it is necessary to mention that such a model is considered np_hard in terms o...
