Model development for forecasting engineering resources assigned to harness design projects

Abstract

A wiring harness is a combination of conductors and connectors to bring signals between devices within an environment to enable a system to perform. Current CAD modeling process helps to predict physical parameters to reduce time during product verification and validation before cost reduction is performed. Design resources forecast and time estimation has been an area to improve since future projects time frames are hard to predict, currently resources are assigned according to designers needs and variate through project development. Previous attempts to develop regression model had been made considering variables hard to estimate before the design is completed. Multiple linear regression is going to be used to determine design time for single wiring harness model and thus, compute the amount of engineering resources assigned to a project. Effective team structure and communication are required to meet out of design dates, avoiding downtimes and allowing a constant workload during the project timeframe. This project was focused on developing a regression model to forecast the amount of engineering resources required to complete an electrical wiring harness routing project with an unfluctuating workload in a defined period.
