Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

Market characteristics, including intrinsic demand and customer sensitivity on price and product performance level, are distinct at different markets. Comparisons of various product development strategies in one market or two geographically separated markets are conducted for three classes of products: development intensive products (DIPs) with constant unit cost, marginal cost-intensive produc...

Demand forecasting is a crucial component of revenue management, as forecasts are almost always inputs into optimization routines for pricing decisions. The performance of many revenue management systems often depends critically on the quality of demand forecasts. Indeed, industry estimates suggest that a 20% reduction of forecast error may lead to 1% incremental increase in revenue (Talluri an...

With a sample of new technology ventures in China, we investigated the contingent effect of strategic decision comprehensiveness on new product performance and product quality. The relationship between strategic decision comprehensiveness and new product performance was negatively moderated by technology uncertainty but positively moderated by demand uncertainty. The effect of decision comprehe...

  This paper aimed at estimation of the per capita consumption of electricity in residential sector based on economic indicators in Iran. The Genetic Algorithm Electricity Demand Model (GAEDM) was developed based on the past data using the genetic algorithm approach (GAA). The economic indicators used during the model development include: gross domestic product (GDP) in terms of per capita and ...

• Develop exact and approximation algorithms to solve the model. Derived closed-form solutions for three special cases. Conservative algorithm dominates large-scale instances. Seek best budget of uncertainty by cross validation method. This work studies a Robust Multi-product Newsvendor Model with Substitution (R-MNMS), where demand substitution rates are stochastic subject cardinality-constrai...
