A combinatorial formulation for optimal sizing, scheduling and shift policy in designing the milling section of a ceramic tile industrial plant

Abstract A modelling approach to optimally design batch labor intensive units is proposed. It stands on the trade-off between the depreciation cost of the equipment to install and the cost of resources, such as energy and manpower. The plant schedule is modelled employing a discrete Resources Task Network framework. It allows the inclusion of resources availability constraints in the design problem formulation, such that the problem of finding the optimal shift policy is inclosed. The resulting modelling strategy is applied to the design of the grinding section of a ceramic tile industrial plant.
