a bi-objective mathematical model for production planning in glass industry: an integrated approach

Glass industry is diverse, both in terms of production process and manufacturing techniques meanwhile, the production of glass containers is a large part of the glass industry the present study focused on decision-making with regard to production planning in glass container industry which is a semi-continuous process industry the aim was to propose a model with a comprehensive view; in fact, attempts were made to acknowledge and include the objectives and constraints of various stakeholders in the model to this end, in addition to profit maximization which is important from a sales perspective, the perspective of production stakeholders, ie production managers, has been included in the model accordingly, an integrated model is proposed for decision-making regarding production planning which simultaneously maximizes profit and production level next, to evaluate the model, a numerical example taken from a large glass container production company in iran is considered in terms of the proposed model and then solved to solve the bi-objective model, the weighting method was utilized finally, results are reported based on various weights where the final decision-maker can make the best decision for production planning based on the conditions
