An integrated production-marketing planning model With Cubic production cost function and imperfect production process

An integrated production and preventive maintenance planning model with imperfect maintenance in multi-state system

Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

An Integrated Aggregate Production Planning Model with Two-Phase Production System and Maintenance Costs

Aggregate production planning (APP) is one of the most important issues carried out in manufacturing environments which seeks efficient planning, scheduling and coordination of all production activities that optimizes the company's objectives. In this paper, we develop a mixed integer linear programming (MILP) model for an integrated aggregate production planning system with closed loop supply ...

Joint pricing and production management: a geometric programming approach with consideration of cubic production cost function

Coordination and harmony between different departments of a company can be an important factor in achieving competitive advantage if the company corrects alignment between strategies of different departments. This paper presents an integrated decision model based on recent advances of geometric programming technique. The demand of a product considers as a power function of factors such as produ...

An EPQ model for an imperfect production process with fuzzy cycle time and quality screening

This study has developed a production inventory model where the cycle timeis fuzzy, the existence of defective products is assumed in each batch andproduct screening is performed both in-production and after-production.Triangular fuzzy numbers serve to model uncertainties in the cycle time, anda fuzzified total inventory profit function is created by thedefuzzifica...

An integrated production - inventory model with imperfect production process in buoyant market

In this study, an integrated production-inventory model is developed from the manufacturers and retailer’s point of view when demand of a product is increasing with the time. The model assumes partial backlogging, imperfect production process and multiple deliveries. The elapsed time until the production process shifts is assumed to be randomly distributed. A numerical example including the sen...
