In this paper, we formulate and solve an economic order quantity model with default risk. Our main purpose is to investigate retailer's optimal replenishment time and credit period for deteriorating items under selling price-dependent demand while maximizing profit per unit time. Here, shortages are allowed and items are partially backlogged for interested customers. We show that optimal replenishment time and credit period not only exist but they are also unique. We solve the proposed problem analytically. An algorithm is presented to derive the optimal solution of the model. The mathematical model is evaluated by numerical examples. We use Mathematica to obtain a global maximum solution to the optimal cycle time and the optimal credit period for the proposed model. A sensitivity analysis with respect to major parameters is performed in order to examine the stability of our model. At the end of the paper, conclusions are drawn and an outlook of possible future directions is depicted.

Analysis of an inventory system under supply uncertainty Gullu, R; Onol, E; Erkip, N (Elsevier BV, 1999-03-20) In this paper, we analyze a periodic review, single-item inventory model under supply uncertainty. The objective is to minimize expected holding and backorder costs over a finite planning horizon under the supply constraints. The uncertainty in supply is modeled using a three-point probability mass function. The supply is either completely available, partially available, or the supply is unavailable. Machine breakdowns, shortages in the capacity of the supplier, strikes, etc., are possible causes of uncerta...
Effect of learning on line-of-balance scheduling Arditi, David; Tokdemir, Onur Behzat; Suh, Kangsuk (2001-01-01) An approach to formulate learning rates and include them in line-of-balance (LOB) calculations is proposed in this paper. Learning rates are generated by modifying historical learning rates of typical construction activities and by incorporating the impact of relevant factors such as, number of operations in one unit, activity complexity, and job and management conditions. Fuzzy set theory is used to develop production rules to treat both factual and uncertain information. An S-type membership function is u...
The effects of volatility on growth and financial development through capital market imperfections Aysan , Ahmet Faruk (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2007-6-1) This paper provides a model to account for the empirical evidence that volatility reduces growth. In the model, greater volatility increases the cost associated with capital market imperfections and induces the financial intermediaries to charge higher interest rates. The model is based on one of overlapping generations with two types of technologies. The more productive technology requires fixed investment in the first period. Individual with income less than the amount of fixed investment may borrow in fi...
The Impact of Modeling on Robust Inventory Management Under Demand Uncertainty Solyali, Oguz; Cordeau, Jean-Francois; Laporte, Gilbert (2016-04-01) This study considers a basic inventory management problem with nonzero fixed order costs under interval demand uncertainty. The existing robust formulations obtained by applying well-known robust optimization methodologies become computationally intractable for large problem instances due to the presence of binary variables. This study resolves this intractability issue by proposing a new robust formulation that is shown to be solvable in polynomial time when the initial inventory is zero or negative. Becau...
Effect of using extreme years in hydrologic model calibration performance Göktaş, Recep Kaya; Tezel, Ulaş; Kargı, Pınar Gökçe; Ayvaz, Mustafa Tamer; Tezyapar, İpek; Mesta, Buket; Kentel Erdoğan, Elçin (2017-12-15) Hydrological models are useful in predicting and developing management strategies for controlling the system behaviour. Specifically they can be used for evaluating streamflow at ungaged catchments, effect of climate change, best management practices on water resources, or identification of pollution sources in a watershed. This study is a part of a TUBITAK project named "Development of a geographical information system based decision-making tool for water quality management of Ergene Watershed using pollut...
