Dynamic Scheduling Framework to Overcome Deficiency of Skilled Workers

Abstract

-Substanti al investments in infrastructure worl d over and rapi d advancement in construction technolog y has created acute shortage of skilled workers. The skill deficiency gets aggravated further due to absenteeism, migration, etc. In practice, i t was observed that there exist several parti ally trained semi-skilled workers having expertise in one or more trade. Using these semi-skilled workers as substitute can address the shortage of skilled workers to some extent. On the contrary, skilled workers alone are considered while pl anning and scheduling in most of the construction projects. Here, the potenti al capability of these parti ally trained workers remains unexploited because of their default groupi ng with unskilled workers.The root cause of this skill treatment can be the absence of standardised system of screening and classification of workers into di fferent skill category as highly skilled, skilled, semi -skilled, or unskilled and the ambiguity in updating or maintaining the worker's database. Hence, the objecti ve of the present study is to review the "skill" levels and the worker's skill utilization to the maxi mum extent possible. To achieve this, a framework has been proposed to generate worker's multi skill database (WMSD) and dynamic scheduling to address the uncertainty caused by deficit of skilled workers.
