    Open shop scheduling problem (OSSP) can basically be defined as a scheduling problem where each job has just one operation to be processed on each machine and operation sequence is free to decide. It is usually seen in facilities that produce similar product families. In this study a Memetic algorithm is proposed for solving the OSSP, and the results are promising.

    A Total Productive Maintenance Implementation in a Manufacturing Company Operating in Insulation Sector in Turkey
    (IEEE, 2015) Baysal, Mehmet Emin; Sumbul, Mehmet Onur; Ekicioglu, Erdem
    In this study, to calculate Overall Resource Effectiveness (ORE), planned downtime, facility downtime, setup and adjustments, material shortages, manpower absence, operator performance losses are found out after observing 4 expanded polystyrene (EPS) machines for 23 days, in 3 shifts a day. In the light of this data readiness, facility availability, mold changeover efficiency, material availability, manpower availability, performance efficiency, quality rate values are found and ORE values for each machine are calculated. Results showed an undeniable need to implement TPM, and suggestions followed.
