A two-echelon allocation model and the value of information under correlated forecasts and demands
Gullu, R (1997-06-01)
In this article we explore the effects of incorporating forecasts explicitly in a two-echelon allocation model which consists of a central depot and several retailers. In particular, we investigate the possible benefits on the system costs and inventory levels. The depot does not hold any inventory and the demand is observed only at the retailers. Under a general correlated demand-forecast structure we obtain the approximate system-wide order-up-to level and the expected system cost. In order to assess the ...
A domain framework approach offering default relations
Kargı, Ersin Eray; Doğru, Ali Hikmet; Department of Computer Engineering (2005)
In order to use components that are developed for a domain, domain knowledge is required. If the default relations in a domain are offered by a framework, this can be a starting point for the application engineer as an important kind of domain knowledge. A generic design for creating and saving a domain is implemented in this thesis. This approach starts with creating a domain from components and relations among these components. The relations and components are saved once and used several times. In additio...
A two-echelon inventory model with stock-dependent demand and variable holding cost for deteriorating items
Pervin, Magfura; null, null; Kumar Roy, Sankar; Wilhelm Weber, Gerhard (American Institute of Mathematical Sciences (AIMS), 2017)
In this study, we develop an inventory model for deteriorating items with stock dependent demand rate. Shortages are allowed to this model and when stock on hand is zero, then the retailer offers a price discount to customers who are willing to back-order their demands. Here, the supplier as well as the retailer adopt the trade credit policy for their customers in order to promote the market competition. The retailer can earn revenue and interest after the customer pays for the amount of purchasing cost to ...
A multiple criteria sorting approach based on distance functions
Çelik, Bilge; Karasakal, Esra; İyigün, Cem; Department of Industrial Engineering (2011)
Sorting is the problem of assignment of alternatives into predefined ordinal classes according to multiple criteria. A new distance function based solution approach is developed for sorting problems in this study. The distance to the ideal point is used as the criteria disaggregation function to determine the values of alternatives. These values are used to sort them into the predefined classes. The distance function is provided in general distance norm. The criteria disaggregation function is determined ac...
A multi-objective approach for dynamic missile allocation using artificial neural networks for time sensitive decisions
Karasakal, Orhan; Karasakal, Esra; Silav, Ahmet (2021-01-01)
In this study, we develop a new solution approach for the dynamic missile allocation problem of a naval task group (TG). The approach considers the rescheduling of the surface-to-air missiles (SAMs), where a set of them have already been scheduled to a set of attacking anti-ship missiles (ASMs). The initial schedule is mostly inexecutable due to disruptions such as neutralization of a target ASM, detecting a new ASM, and breakdown of a SAM system. To handle the dynamic disruptions while keeping efficiency h...
