Life cycle energy and CO2 emissions analysis of food packaging: an insight into the methodology from an Italian perspective
2016
Packaging is strictly connected to environmental issues as it is a product characterised by high material consumption rate; it is often transported over long distances and has a short life. Providing environmental analysis is, therefore, urgent to identify energy and resources efficient solutions. The paper, taking advantage of a real case study, presents a life cycle-based comparative analysis among three different food packaging systems. The paper compares the life cycle of tin steel, polypropylene and glass-based packaging of an Italian preserves producer. The analysis leads to the conclusion that, for the baseline scenario, polypropylene packaging represents the greenest solution, where…
Lope de Vega y la historia en los escenarios de los siglos XX y XXI
2013
This paper aims to examine, on the one hand, the presence of Lope’s historical dramas on contemporary stage to confirm their continuity; and, on the other, to reflect on the distinctive features of the staging of these dramas from a specific corpus of performances dating from the last decades. The goal is to observe the current relevance of these dramas and performances, to study under what ethical and aesthetic assumptions characters are now represented and the historical episodes that Lope used in the creation of his fictions, as well as to analyze the possible connections between History, Lope and the audience of the 21st century.

Simulating term structure of interest rates with arbitrary marginals
2011
Decision models under uncertainty rely their analysis on scenarios of the economic factors. A key economic factor is the term structure of interest rates (yields). Simulation models of the yield curve usually assume that the conjugate distribution of the interest rates is lognormal. Dynamic models, like vector auto-regression, implicitly postulate that the logarithm of the interest rates is normally distributed. Statistical analyses have, however, shown that stationary transformations (yield changes) of the interest rates are substantially leptokurtic, thus posing serious doubts on the reliability of the available models. We propose in this paper a VARTA model (Biller and Nelson, 2003) to s…

Speciālistu un pacientu viedoklis un problēmas saistībā ar grozījumiem Ministru kabineta noteikumos Nr.899 par zāļu vispārīgā nosaukuma izrakstīšanu
2021
2020. gada 1. aprīlī tika mainīta Latvijas valsts kompensējamo zāļu izrakstīšanas kārtība,kuru regulē MK noteikumi Nr.899 – ārsts receptē norāda aktīvo vielu, nevis konkrētu medikamenta nosaukumu, aptiekas no vienādas iedarbības un devas zālēm izsniedz kompensējamās zāles par zemāko (references) cenu. Darba aktualitāti nosaka ar MK noteikumu grozījumiem saistītās problēmsituācijas farmaceitu darbā un klientu apmierinātībā. Pētījuma mērķis: noskaidrot Latvijas farmācijas speciālistu un iedzīvotāju viedokli par MK noteikumu grozījumiem. Tika veikta respondentu anketēšana. Darba rezultātā tika secināts: farmācijas speciālistu darba ikdiena ir kļuvusi sarežģītāka. References medikamentu biežā m…

Multi-scenario multi-objective robust optimization under deep uncertainty: A posteriori approach
2021
This paper proposes a novel optimization approach for multi-scenario multi-objective robust decision making, as well as an alternative way for scenario discovery and identifying vulnerable scenarios even before any solution generation. To demonstrate and test the novel approach, we use the classic shallow lake problem. We compare the results obtained with the novel approach to those obtained with previously used approaches. We show that the novel approach guarantees the feasibility and robust efficiency of the produced solutions under all selected scenarios, while decreasing computation cost, addresses the scenario-dependency issues, and enables the decision-makers to explore the trade-off …
A spreadsheet modeling approach to the Holt–Winters optimal forecasting
2001
Abstract The objective of this paper is to determine the optimal forecasting for the Holt–Winters exponential smoothing model using spreadsheet modeling. This forecasting procedure is especially useful for short-term forecasts for series of sales data or levels of demand for goods. The non-linear programming problem associated with this forecasting model is formulated and a spreadsheet model is used to solve the problem of optimization efficiently. Also, a spreadsheet makes it possible to work in parallel with various objective functions (measures of forecast errors) and different procedures for calculating the initial values of the components of the model. Using a scenario analysis, the se…
A parsimonious model for generating arbitrage-free scenario trees
2016
Simulation models of economic, financial and business risk factors are widely used to assess risks and support decision-making. Extensive literature on scenario generation methods aims at describing some underlying stochastic processes with the least number of scenarios to overcome the ‘curse of dimensionality’. There is, however, an important requirement that is usually overlooked when one departs from the application domain of security pricing: the no-arbitrage condition. We formulate a moment matching model to generate multi-factor scenario trees for stochastic optimization satisfying no-arbitrage restrictions with a minimal number of scenarios and without any distributional assumptions.…
