A goal geometric programming problem (G 2 P 2) with logarithmic deviational variables and its applications on two industrial problems

Ghosh, Payel; Roy, Tapan - In: Journal of Industrial Engineering International 9 (2013), pp. 1-9

A very useful multi-objective technique is goal programming. There are many methodologies of goal programming such as weighted goal programming, min-max goal programming, and lexicographic goal programming. In this paper, weighted goal programming is reformulated as goal programming with...

Reliability analysis of a robotic system using hybridized technique

Kumar, Naveen; Lather, J. S. - In: Journal of Industrial Engineering International 14 (2018) 3, pp. 443-453

In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system...

A new statistical method for design and analyses of component tolerance

Movahedi, Mohammad Mehdi; Khounisiavash, Mohsen; Otadi, … - In: Journal of Industrial Engineering International 13 (2017) 1, pp. 59-66

Tolerancing conducted by design engineers to meet customers' needs is a prerequisite for producing highquality products. Engineers use handbooks to conduct tolerancing. While use of statistical methods for tolerancing is not something new, engineers often use known distributions, including the...

Estimation of capital requirements in downturn conditions via the CBV model: Evidence from the Greek banking sector

Papalamprou, Konstantinos; Antoniou, Paschalis - In: Operations Research Perspectives 6 (2019), pp. 1-10

One of the main drawbacks of the original CreditRisk+ methodology is that it models the default rates of the sectors (e.g. industry) as independently distributed random variables. Such an assumption has been considered as unrealistic and various approaches have been proposed in order to overcome...

Aggregated GP-based optimization for contaminant source localization

Krityakierne, Tipaluck; Baowan, Duangkamon - In: Operations Research Perspectives 7 (2020), pp. 1-10

Recently a new simulation-based optimization benchmark of groundwater contaminant source localization problems has been introduced to the hydrogeological science community. Given information on contaminant concentration levels at each monitoring well and each time step, its objective is to...

Optimization of capacity expansion in potential-driven networks including multiple looping: a comparison of modelling approaches

Lenz, Ralf; Becker, Kai Helge - In: OR Spectrum 44 (2021) 1, pp. 179-224

In commodity transport networks such as natural gas, hydrogen and water networks, flows arise from nonlinear potential differences between the nodes, which can be represented by so-called potential-driven network models. When operators of these networks face increasing demand or the need to...

Who gets a mammogram amongst European women aged 50-69 years?

Wuebker, Ansgar - In: Health Economics Review 2 (2012) 6, pp. 1-13

On the basis of the Survey of Health, Ageing, and Retirement (SHARE), we analyse the determinants of who engages in mammography screening focusing on European women aged 50-69 years. A special emphasis is put on the measurement error of subjective life expectancy and on the measurement and...

The impact of pharmaceutical innovation on cancer mortality in Mexico, 2003-2013

Lichtenberg, Frank R. - In: Latin American Economic Review 26 (2017) 1, pp. 1-22

I assess the impact that pharmaceutical innovation had on cancer mortality in Mexico during the period 2003-2013, by … investigating whether there were larger declines in the age-standardized mortality rate of cancer sites (breast, lung, colon, etc ….) that were subject to more pharmaceutical innovation, controlling for changes in the age-standardized cancer incidence rate …
