On the
Optimality of Multi Item Integrated Production Inventory Systems

Abstract: In some industrial systems like petrochemicals, the same raw
materials are used in producing several products. However, most of the classical
production inventory systems treat the economic order quantities (EOQ) of raw
materials, which are used in producing certain final products, separately of the
economic production quantities (EPQ) of these products. This may result in sub-optimization
of both the (EOQ)'s of raw materials and the (EPQ)'s of final products. But,
when raw materials are used in production, the ordering quantities for raw
materials are dependent on the economic batch size and the schedule of the final
products. By integrating the procurement and production subsystems, the degree
of sub-optimality is reduced. In this paper, a unified inventory model of
integrated production inventory systems, where each of production, demand and
deterioration rates of final products and deterioration rates of raw materials
are general functions of time, is considered. Shortages for final products are
allowed but are partially backordered. All cost components are affected by both
inflation and time value of money. The objective is to find an optimal
production schedule for each product in any inventory cycle so that the overall
total relevant inventory cost for these integrated systems is minimized. We
develop an exact formula for the total inventory cost per unit of time. Then, we
use rigorous mathematical methods to find the optimal production schedule for
each final product of these integrated inventory systems.
