In this paper we consider a make-to-stock production system whose permanent production capacity can be increased temporarily by making use of some contingent resources, while this capacity acquisition has a constant lead time associated with it. We present a model where the capacity management problem is handled in an integrated manner with the inventory management, under non-stationary and sto...

Demand fluctuations that cause variations in output levels will affect a firm’s technical inefficiency. To assess this demand effect, a demand-truncated production function is developed and an “effectiveness” measure is proposed. Often a firm can adjust some input resources influencing the output level in an attempt to match demand. We proposes a short-run capacity planning method, termed proac...

Although revenue management (RM) originates from service industries, its ideas are also relevant for manufacturing environment. In this paper, we consider RM approaches for demand fulfillment in a make-to-stock (MTS) production system with known exogenous replenishments and stochastic demand from multiple customer classes. We propose a safety margin model which borrows the “safety stock” idea f...

In this paper, a production inventory model is considered for stochastic demand with the effect of inflation. Generally, every manufacturing system wants to produce perfect quality items. However, due to real-life problems (labor problems, machine breakdown, etc.), a certain percentage of products are of imperfect quality. The imperfect items are reworked at a cost. The lifetime of a defective ...

Manna and Chaudhuri (Eur. J. Oper. Res. 171(2):557–566, 2006) presented a production-inventory system for deteriorating items with demand rate being a linearly ramp type function of time and production rate being proportional to the demand rate. The two models without shortages and with shortages were discussed. Both models were studied assuming that the time point at which the demand is stabil...

In this paper, we use market segmentation approach in multiproduct inventory production system with deteriorating items. The objective is to make use of optimal control theory to solve the production inventory problem and develop an optimal production policy that maximize the total profit associated with inventory and production rate in segmented market. First, we consider a single production a...

A real economic growth only comes from increasing quality and quantity of the factors of production. Most production systems produce items which are of imperfect quality. In a production/inventory situation items which are received or produced are not of perfect quality. Thus the presence of defects which is inevitable in a produced/ordered lot is sorted out by the process of screening. Handlin...

The management of production and inventory control associated activities in remanufacturing production system has received attention by practitioners in the last two decades. This is due to the increased productivity, limited supply of virgin materials, stringent environmental requirements for product disposal and treatment as well as substatial change in global sustainability regulations. In o...
