In the global supply chain system it is required to integrate production scheduling and distribution planning, in order to be more efficient and to get more economics advantages. This paper presents seafood production planning and scheduling of a fishery manufacture company which produces simultaneously multi kind of seafood products from several classes of raw fish resources. The perishability...

We develop the first approximation algorithm for periodic-review perishable inventory systems with setup costs. The ordering lead time is zero. The model allows for correlated demand processes which generalize the well-known approaches to model dynamic demand forecast updates. The structure of optimal policies for this fundamental class of problems is not known in the literature. Thus, finding ...

Blood banking systems in the United States over the past decade have been faced with a volatile demand for blood, specifically, a decrease in demand for red blood cells, for a variety of reasons. This change in the blood supply chain landscape, accompanied by an increasing emphasis on cost efficiency, is a driver of Mergers & Acquisitions between blood banks. In this paper, we first present sup...

This paper conducts a probabilistic analysis of an important class of heuristics for multiitem capacitated lot sizing problems. We characterize the asymptotic performance of so-called progressive interval heuristics as T , the length of the planning horizon, goes to infinity, assuming the data are realizations of a stochastic process of the following type: the vector of cost parameters follows ...

We consider a service facility system with perishable inventory with finite number of servers. Each server having one perishable item for providing service. The arrival of a customer at the system according to independent Poisson Processes with rate  through a single channel. The service time of the customer is exponentially distributed with mean  1/ and the item in stock has exponential life...

Mangoes account for approximately half of all tropical fruits produced worldwide. India is the largest mango producer, accounting for about half of the global mango production. But, less than five per cent of the produced mangoes are processed and mango pulp is the main export product both in terms of volume and value. Contract system is the major marketing system in the supply of mangoes becau...

This paper proposes a framework for online service applications based on Service Science which identifies and enables a better understanding of the different issues faced by online service designers, engineers, and delivery personnel. The application of the Service Science framework is made possible by carefully distinguishing online service applications not only from traditional personal softw...

This paper proposes a discrete capacitated covering location-allocation model for pharmaceutical centers. In the presented model, two objectives are considered; the first one is minimization of costs and the second one try to maximize customer satisfaction by definition of social justice. Social justice in the model means that we consider customers satisfaction by using distance. the introduced...

Seasonal production, weather abnormalities, and high perishability introduce a degree of volatility to potato prices. Price is said be asymmetric when positive negative shocks the same magnitude affect it in dissimilar way. GARCH symmetric model, cannot capture price volatility. EGARCH, APARCH, GJR-GARCH models are popularly used In this paper, an attempt made model weekly wholesale modal potat...
