Interpretive Structural Modeling (ISM) for Recovery of Heat Energy

摘要

In this paper twenty nine factors responsible for heat transfer in the recovery of heat from hot dyeing waste slurry and its Interpretive Structural Modeling (ISM) has been developed. In this systematic approach of ISM, first of all a concept model of the problem has been formulated, followed by the formulations of Structural Self Interaction Matrix (SSIM) and Reachability Matrix. The level of significance of each factor has been derived by level partitioning. The initial digraph is prepared on the basis of the canonical matrix. ISM based model is finalized after checking for conceptual inconsistency and necessary modifications. The MICMAC analysis is also conducted with the help of driving and dependence diagram, which states that factor 4 (mass flow rate of working medium (water)) and factor 5 (Inlet temperature of working fluid (slurry)) are the major parameters for heat recovery and needs more attention.
