Co-firing biomass and coal in retrofitted power plants is an efficient means to reduce carbon dioxide emissions in the energy sector. Under IPCC reporting rules, the impacts of energy produced from biomass would not be reported in the energy sector, thereby effectively lowering the emission...

A process system is designed for material transformations that produce certain functional chemicals while usually consuming large amounts of energy. Materials in process systems have long been the major focus of investigation to achieve better economic performance. Rising energy prices and...

Purpose – To select the best strategies in the presence of both deterministic and non‐deterministic data in uncertain environments, without relying on weight assignment by decision makers, this paper aims to propose an innovative approach, which is based on mathematical programming called...

Considers that the problem of determining the Dodge‐Romig lot tolerance per cent defective (LTPD) double sampling plan (DSP) under the fuzzy environment satisfies the consumer’s risk closely and is an extension of Chakraborty’s work. Models the problem as fuzzy mathematical programming...

One of the major components of an audit plan is risk assessment. Risk factors vary among organizations, and internal auditors must review their own organizational cultures to determine audit exposure. In order to minimize the risk, the internal audit department must develop an audit plan that...

Purpose – The purpose of this study is to examine the cost efficiency of 58 branches of a major Greek commercial bank, in six major Greek cities, for the years 2000 and 2001. Design/methodology/approach – The efficiency is measured through the data envelopment analysis (DEA) method. Using...
