Industrial demand response: How network tariffs and regulation (do not) impact flexibility provision in electricity markets and reserves

Richstein, Jörn C.; Hosseinioun, Seyed Saeed - In: Applied Energy 278 (2020)

Incentives for industrial loads to provide demand response on day-ahead and reserve markets are affected both by network tariffs, as well as regulations on the provision of flexibility in different markets. This paper uses a numerical model of the chlor-alkali process with a storable...

A cloudy fuzzy economic order quantity model for imperfect-quality items with allowable proportionate discounts

De, Sujit Kumar; Mahata, Gour Chandra - In: Journal of Industrial Engineering International 15 (2019) 4, pp. 571-583

In the traditional economic order quantity/economic production quantity model, most of the items considered are of perfect type. But this situation rarely takes place in practice. Thus, in this paper, an economic order quantity model with imperfect-quality items is developed....

Resource allocation procedures for unknown sales response functions with additive disturbances

Gahler, Daniel; Hruschka, Harald - In: Journal of Business Economics 92 (2021) 6, pp. 997-1034

We develop a modified exploration–exploitation algorithm which allocates a fixed resource (e.g., a fixed budget) to several units with the objective to attain maximum sales. This algorithm does not require knowledge of the form and the parameters of sales response functions and is able to cope...
