Parallel Machine Scheduling for Minimizing Flowtime: Case Study at Aircraft Company X Turnin and Milling Departments
Company X in 2017 has a delay in the Turning and Milling department of 58% of the total order of 2,334. The actual condition is the number of machines used, namely 5 CNC machines with a production capacity of 230.4 hours / week and the number of work orders from 2013-2018 that must be done is 2767,458 hours. The delay was due to the absence of an appropriate engine scheduling system. Modeling uses mathematical models and runs using lingo software. The results of calculations using LINGO for mathematical models are 14,274 hours with a calculation time of 17 minutes 55 seconds.
