Analysis of Results in OPUTANALYSIS

Introduction to Analysis

• The session focuses on analyzing results using OPUTANALYSIS, emphasizing the importance of reviewing written materials beforehand, including models with completion conditions and confidence intervals.

Example Setup

• An example from Altyoki Melamed's book is introduced, featuring a single machine called "Finish and Operation" that processes two types of parts: G1 and G2.

• Parts of type G1 arrive every 3 hours (exponentially distributed with a mean of 2 hours), while type G2 arrives every 3 hours as well (mean of 4 hours). Both types have fixed processing times (G1: 1 hour; G2: 1.4 hours).

Processing Mechanism

• The parts are processed using a FIFO queue system, meaning the first part to arrive is the first to be processed. All parts have equal priority.

• The simulation will run for 10,000 hours to observe the behavior regarding waiting times for each workstation and delays for both part types.

Model Configuration

• Two modules are created in the model: one for tracking arrival times and another for processing times. Each part type has its respective parameters set up.

• Statistics on delays will be collected in subsequent modules, capturing how long each part waits before being processed.

Statistical Analysis

• After processing is complete, resources will be released, and entities removed. Data on delays will be stored in output files named after each part type (G1 DLi, G2 DLi).
