Case Studies in the Indian Context
Published in Sharmin Khan, Constructability, 2018
DSM is used for study of interrelationship between activities. A DSM is defined as a compact, matrix representation of a project network. It provides an idea about various activities of any process that are interrelated, what information is required to start an activity, what activity will be followed by any previous activity, manages complex projects, does task sequencing and iterations (Yassine, 2004). Steward (1981) also defined DSM as “a methodology to handle dependencies and relations between activities.” Browning (2001) explains that DSM is a representation and analysis tool for the system modeling. A DSM displays the relationships between components of a system in a compact, visual, and analytically advantageous format.

Although there exists a huge potential for demand side management (DSM) in the developing world, it has received less attention in policy making and energy planning in Bangladesh. In designing proper DSM, there are four main challenges: cost of the DSM project; making sure appropriate technology is in place; related system complexity; and the consumers (i.e., the end users of electricity) (Khan 2019c). At the initial stage of DSM strategy selection for any country, ‘energy-saving behaviour’ could play a pivotal role among many different DSM schemes.
A framework for automatic architectural synthesis in conceptual design phase

The representation of the solutions {3} must allow both computers and people to understand the formalism in order to comprehend the generated solutions. The design structure matrix (DSM) representation is well adapted to a computer and can be easily translated into a visual representation based on graphs like SysML or Modelica diagrams for human comprehension. A DSM is a matrix that shows the interconnections between objects of the same type. Bonev et al. (2015) expand the DSM representation in order to take into account several objects of different levels as systems, sub-systems, constraints and attributes and their interconnections. Only objects from the same level are described in the DSM of this paper, even if the presented framework can easily handle more complex representations. Modelica is a language that is usually used to model and simulate the behaviour of a system. Nevertheless, in order to simulate, all internal parameters must be known before running the simulation. In the case of pre-design activities these parameters are not totally known and so simulations cannot be conducted. The Modelica representation could also be used to offer a modelling framework.
A method for coupling analysis of association modules in product family design

The Design Structure Matrix (DSM) is a matrix-based technique to represent and analyse connections among elements within a system or process such as a complex engineered system or a product development process. DSM has been widely used to identify modules within a product, and its use to identify modules across a family of products has been also paid attention to. For example, DSM was used for analysis of identifying product platform elements (Steva et al. 2006). Alizon et al. (2007) extended the basic DSM model to target a three-dimensional tool helping designers for managing variety within a product family. Suh et al. (2010) proposed a systematic framework to quantify and assess the impact of technology infusion early in the product planning cycle through the use of a DSM and the creation of a Delta DSM (ΔDSM) describing the changes to the original system. Luh, Ko, and Ma (2011) suggested a design method for product variety using an extended direct graph and a DSM with different connection strengths between components. Jung and Simpson (2016) introduced an integrated approach that uses generational variety index, product line commonality index and design structure matrix to establish an effective platform redesign strategy.

One of the practical tools that academia has developed to visualise the dependencies between parties or activities is design structure matrix (DSM). Steward (1981) describes DSM as a technique to plan the design process information flow by visualising the use of estimates, iterations and design reviews. The entities can be components of a product or tasks to complete a project, and the matrix can be used to identify appropriate teams, workgroups and an ideal sequence of the tasks (Lindemann, 2009). DSM involves a square matrix with an equal number of rows and columns that shows relationships between elements/tasks in a system. In comparison to other system modelling methods, DSM has two main advantages (Lindemann, 2009): It provides a simple and concise way to represent a complex system.It is amenable to powerful analyses such as clustering (to facilitate modularity) and sequencing (to minimise cost and schedule risk in processes).
