Imprecision in probability values (represented through credal sets) allows a more realistic modelling of uncertainty in decision problems. Uncertainties often lead to partially ordered preferences and, consequently, different criteria of choice may be taken into account. In this paper, we present an algorithm that evaluates an extended version of influence diagrams, where chance variables repre...

Influence diagrams allow for intuitive and yet precise description of complex situations involving decision making under uncertainty. Unfortunately, most of the problems described by influence diagrams are hard to solve. In this paper we discuss the complexity of approximately solving influence diagrams. We do not assume no-forgetting or regularity, which makes the class of problems we address ...

The floriculture industry faces many challenges including increasing energy and input prices, seasonality of its products and international competition. To analyze floriculture demand, we estimate and use simulation analysis to decompose it into market penetration and buying frequency. Understanding what are the factors that influence non-buyers of floral products to become buyers, and the fact...

This is part 1 of a 2-part paper on ethics and physician-industry relationships. Part 1 offers advice to individual physicians; part 2 gives recommendations to medical education providers and medical professional societies. Physicians and industry have a shared interest in advancing medical knowledge. Nonetheless, the primary ethic of the physician is to promote the patient's best interests, wh...

We study the strategic behaviour of management researchers when establishing research partnerships with industry. To this end we developed a framework distinguishing ‘strategic planned’ and ‘opportunitydriven’ behaviour in the process of establishing and managing research partnerships. We also explore how researchers deal with influence of firms on their research. Specifically, we focus on the ...

The current economic situation creates general pressure to increase performance. Any inefficient use of production factors will lead problems and long-term unsustainability in many industries. effects the Covid-19 pandemic also have a negative impact on all sectors economy faster onset fourth industrial revolution. article, therefore, proposes new framework for performance evaluation manufactur...

Claude ZoBell’s recognition of the influence of microorganisms in the ecology of petroleum bearing environments was all encompassing. This translated into a unique contribution over the entire span of the oil industry. Many of his publications in the 1940s and 1950s discussed the key role of microorganisms in the diagenesis of hydrocarbon products. At a time when the industry was treating the s...

campaign contributions from the tobacco industry can influence legislators’ tobaccorelated policy decisions. To our knowledge, there have been no published accounts of tobacco industry contributions to Canadian legislators. As part of a broader study examining Canadian legislators’ attitudes toward tobacco control policies and possible factors that influence those attitudes, we have documented ...

Employees are the most important factor in the success and failure of any organization. The airline industry is a service industry that sells seats to its passengers therefore employees motivation towards their job plays a very important role in serving the customer’s needs. This study focuses on the impact of employee motivation and its components e.g. work environment, pay and benefits, manag...

This study investigates the ethical climate types presented in the Korean tourism industry, the differences in the perceptions of ethical these climate types based on individual/organizational characteristics, and the influence of ethical climate types based on job satisfaction/ organizational commitment. Empirical findings of this study identify six ethical climate types and demonstrate signif...
