Resource optimization of product development projects with time-varying dependency structure

A Multi-objective optimization model for project scheduling with time-varying resource requirements and capacities

Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...

A Simulation-Based Optimization Model for Scheduling New Product Development Projects in Research and Development Centers

a simulation-based optimization approach for the purpose of finding a near-optimal answer can be efficient and effective. In the present paper, first, the mathematical model for the project activity scheduling problem has been presented with a job shop approach. Then, using the Arena 14 software, the simulation model has been designed. Consequently, a numerical example has been solved via runni...

Managing a Portfolio of Product Development Projects under Resource Constraints

Managers of product development (PD) project portfolios face difficult decisions in allocating limited resources to minimize project or portfolio delay. Although PD projects are highly iterative (cyclical), almost all of the vast literature on project scheduling assumes that projects are acyclical. This article addresses this gap with a comprehensive analysis of 31 priority rules (PRs) on 18,48...

Use of Dependency Structure Matrices for Product Development Cycle Time Reduction

Cycle time reduction is an important aspect of integrated product and process development (IPPD). This paper outlines some of the challenges that impede efforts to reduce cycle time for complex system development projects. Several facets of these challenges can be summarized using the general concept of design iterations. After reviewing this concept, the paper provides an overview of a process...
