TLDR
In this article, a Monte-Carlo simulation-based approach was used to determine the placement of activity and rework probabilities that can achieve minimal duration of a project, and the results of the model were analyzed to determine a database for two-activity and three-activity DSMs.Abstract:
Researchers have identified the dependency structure matrix (DSM) as a potential tool to explicitly identify iteration blocks and to evaluate the resulting sequence. Factors such as duration of activity, duration of rework, location of feedback variables, size of block, and number of loops within a block influence the overall duration of a project. The present study traces a pattern underlying the behavior of the block in evaluating the execution sequence. To achieve this objective, a database is generated for two-activity and three-activity DSMs by using a Monte-Carlo simulation based approach. The results of the model are analyzed to determine the placement of activity and rework probabilities that can achieve minimal duration of a project.read more

Analysis of Workflow Variability and Its Impacts on Productivity and Performance in Construction of Multistory Buildings
TL;DR: In this paper, a mixed method of mathematical and simulation modeling was used to analyze performance and productivity at both the trade and project levels of a residential construction project, and performance metrics such as completion times, work-in-process levels, and delays were then measured in different real-life production scenarios.

A Framework for Selecting Construction Project Delivery Method Using Design Structure Matrix
TL;DR: In this paper , a DSM-based PDM selection framework model is proposed that regroups activities and identifies appropriate PDMs by revealing the dependencies and intensities between activities and uses a case to demonstrate the feasibility of the framework.

Modeling impacts of process architecture on cost and schedule risk in product development
TL;DR: This paper integrates several important characteristics of PD processes into a single model, highlighting the effects of varying process architecture and yielding several managerial insights, including: how rework cascades through a PD process, trading off cost and schedule risk, interface criticality, and occasions for iterative overlapping.

Innovation at the speed of information.
TL;DR: The author describes the Design Structure Matrix (DSM), a project management tool that focuses on representing the information flows of a project rather than its work flows, and suggests four ways to improve a company's information flows.
