Abstract
Timely delivery of natural and fresh juice to its’ growing customers is the focus of SCUBED 100%. The CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique) techniques were applied in minimizing the expected time duration for juice production at SCUBED 100%. The current expected production time for a batch stood at 656.66 minutes. Modifications were made on the initial model to minimize the expected duration and after two modification processes, an estimated time duration of 458.33 minutes was realized, saving 198.33 minutes (about 3.3 hours) of production time. This study encapsulates the interplay of theoretical insights and practical implementation, confirming the potential of operational research and management techniques in designing real-world outcomes. SCUBED 100%'s journey towards operational excellence demonstrates the transformative potential of time optimization.
