Assortment optimization with log-linear demand: Application at a Turkish grocery store
Authors:
Publisher and Date:(Elsevıer Sci Ltd, 2019)In retail sector, product variety increases faster than shelf spaces of retail stores where goods are presented to consumers. Hence, assortment planning is an important task for sustained financial success of a retailer in a competitive business environment. In this study, we consider the assortment planning problem of a retailer in Turkey. Using empirical point-of-sale data, a demand model is developed and utilized in the optimization model. Due to nonlinear nature of the model and integrality ...

Bargaining with nonanonymous disagreement: Decomposable rules
Authors:
Publisher and Date:(Elsevier Science Bv, 2011)We analyze bargaining situations where the agents' payoffs from disagreement depend on who among them breaks down the negotiations. We model such problems as a superset of the standard domain of Nash (1950). We first show that this domain extension creates a very large number of new rules. In particular, decomposable rules (which are extensions of rules from the Nash domain) constitute a nowhere dense subset of all possible rules. For them, we analyze the process through which "good" properties ...

Nutrient Dynamics in Flooded Wetlands. I: Model Development
Authors:
Publisher and Date:(ASCE-AMER SOC CIVIL ENGINEERS, 2013)Wetlands are rich ecosystems recognized for ameliorating floods improving water quality and providing other ecosystem benefits. This part of a two-paper series presents a relatively detailed process-based model for nitrogen and phosphorus retention cycling and removal in flooded wetlands. The model captures salient features of nutrient dynamics and accounts for complex interactions among various physical biogeochemical and physiological processes. The model simulates oxygen dynamics and the impact ...

Nutrient Dynamics in Flooded Wetlands. II: Model Application
Authors:
Publisher and Date:(ASCE-AMER SOC CIVIL ENGINEERS, 2013)In this paper the authors applied and evaluated the wetland nutrient model that was described in Paper I. Hydrologic and water quality data from a small restored wetland located on Kent Island Maryland which is part of the Delmarva Peninsula on the eastern shores of the Chesapeake Bay was used for this purpose. The model was assessed through various methods against the observed data in simulating nitrogen (N) phosphorus (P) and total suspended sediment (TSS) dynamics. Time series plots of observed ...
