METHOD FOR SCHEDULING PRODUCTION ON A CONTINUOUS GALVANIZING LINE

A method for setting the production schedule of a multiplicity of galvanized coils of metallic strip on a continuous galvanizing line is provided, the method including the steps of evaluating, for each possible combination of two uncoated coils, the impact of the transition from the first uncoated c...

Beschreibung
Zusammenfassung:	A method for setting the production schedule of a multiplicity of galvanized coils of metallic strip on a continuous galvanizing line is provided, the method including the steps of evaluating, for each possible combination of two uncoated coils, the impact of the transition from the first uncoated coil to the second uncoated coil on the quality of the galvanized coils, allocating to each possible combination of uncoated coils a weighting factor which depends on the results of the previous step and which takes into account the line constraints, computing the results of the previous step by calculating, for a number of possible schedules of the multiplicity of uncoated coils, a score which depends on the sum of the weighting factors attributed to the combinations of uncoated coils involved in the given schedule and by selecting the schedule with the optimal score.
