Stochastic programming with step decision rules, SPSDR, is an attempt to overcome the curse of computational complexity of multistage stochastic programming problems. SPSDR combines several techniques. The first idea is to work with independent experts. Each expert is confronted with a sample of scenarios drawn at random from the original stochastic process. The second idea is to have each expe...

31 Plant species differ in their ability to transform available recourses to biomass and to respond 32 in a plastic way to environmental circumstances; we hypothesized that such differences 33 among four weed taxa of Papaver would explain differences in their competitive response. 34 We first compared two populations each of Papaver rhoeas L., P. dubium L. ssp. dubium, P. 35 dubium L. ssp. leco...

The article presents an approach to the corporation's capital structure management based on criterion of maximizing return equity (ROE). basis this is determination expediency attracting borrowed resources from point view balancing financial risk and profitability. toolkit for optimizing corporation substantiated, taking into account indicator leverage, which ensures most effective proportional...

recently, women’s participation has increased in the workplaces. therefore it is a challenge for contemporary managers to help employees to balance their work and family responsibilities. this paper aims to identify factors affecting the work-family balance. sample included 261 women employed at a number of universities in tehran. data is collected from the questionnaire. correlation and multip...

today, shortage of fresh water especially in arid and semi-arid regions has caused several difficulties.  whatever more than 70 percent of the earth is water, but also high salinity of water resources, caused serious restrictions for human to use these resources. therefore, desalination has attracted all attentions more than any time. between different water consumers in the country, agricultur...

Artificial intelligence (AI) has become an integral part of every industry. With the emergence big data, industries, and more especially textile apparel (T&A) industry, are on brink relationships with consumers, suppliers, competitors. They need to handle different scenarios a multitude complex correlations dependencies between them uncertainties arising from human interaction. It imperative fo...

The paper presents a new modeling framework enabling to evaluate the cyclic steady state of a given system of concurrently flowing cyclic processes (SCCP) sharing common system resources while interacting on the base of a mutual exclusion protocol. Assuming a given topology of cyclic routes passing on by subsets of system resources, a set of dispatching rules aimed at recourses’ conflicts resol...

The problem of finding quality information and services on the Web is analyzed. We present two user-centered evaluation methodologies to characterize the quality of the Web documents and Web sites that contain these Web documents. These evaluation methodologies are designed using a fuzzy linguistic approach in order to facilitate the expression of qualitative and subjective judgements. These me...

In this paper we present User Participatory Sketching as a complementary approach to user requirements gathering methods. We apply the approach in an empirical study and investigate its potential benefits early in interaction design processes. The findings from a case study suggest the User Participatory Sketching approach can complement conventional user requirement gathering techniques in the...
