This paper concerns with the integration of rough set theory with the Best Worst method to evaluate information system performance within supplier selection problem of biofuel companies. First, a set ...of main criteria and sub-criteria are collected and then to include uncertainty in decision making, rough set theory is employed. The rough best worst method is applied for weighing and supplier evaluation with respect to information system performance and environmental impacts. Further, a case study is conducted for biofuel company supplier selection and the results imply the effectiveness of the approach in tactical performance evaluation. The best criteria effective on the green supplier selection of ISs performance is determined to be Quality.
Any company with growth ambitions must have a formal and well-defined mobile strategy, or it could lose, thanks to this, the promised economic recovery. BYOD (Bring Your Own Device) refers to the ...fact that members of company ecosystems (management, employees, partners, etc.) will increasingly use their own personal mobile devices (smartphone, tablet etc.) in the future to work from anywhere and anytime. The phenomenon has been for several years now words that define concepts of deploying hyperbolised businesses around the world as essential concepts of the future. An all-new model in companies around the world is CYOD (Choose Your Own Device), where companies allow employees to choose the devices they want to use in the office, which is becoming more and more popular as an alternative to the BYOD phenomenon in the business environment. Following the accommodation of companies and employees with the BYOD program, the emergence of the new CYOD program proves the need and also the efficiency of the transformation and development of BYOD into a new form of use of devices in the workplace. The paper aims to present several security aspects of BYOD technology, with examples for Europe and Romania, and the ever-faster shift to CYOD technology
Purpose
The purpose of this paper is to test if the order in which potential customers receive company related information and product related information about a new brand can influence their trust ...and purchase intentions towards that brand. The empirical context is when both product and company are new to a market and share a brand name.
Design/methodology/approach
Two experiments, each involving a different product type, are used to test whether higher trust and purchase intentions towards a new brand are likely when company related information is provided first compared to when product related information is provided first.
Findings
Company related information is more diagnostic than product related information and carries more weight in initial consumer trust judgements particularly when it is evaluated first. There is a similar primacy effect on purchase intentions but one mediated by initial trust. The effect is more pronounced for product types that involve a higher perceived risk when buying.
Research limitations/implications
This paper adds to our understanding of the respective roles of corporate and product communication in the process of brand trust formation for newly launched brands by evidencing and explaining primacy effects related to the greater diagnosticity of corporate brand information.
Practical implications
Market entrants should communicate information about their company before promoting their products.
Originality/value
While prior work has shown that both company and product related information can influence customers’ trust towards a new brand, there has been no assessment of the benefits from ordering these communications. The focus here is then on the processes involved in brand trust formation, rather than on identifying specific antecedents of brand trust.
This article discusses a methodological approach to building models for assessing the effectiveness of a program (project) for creating or modernizing an information security system in the interests ...of ensuring the sustainability and competitiveness of a company in the face of increasing threats to the integrity, confidentiality, availability, and reliability of information that is important for its activities. At the same time, the effectiveness of a program (project) is understood as the degree of use of the opportunities allocated for their implementation of material, intangible, and temporary resources to achieve the set goals. When mathematically formalizing a generalized efficiency indicator, it is taken into account that the implementation of technical, technological, organizational, and other elements (events) included in this program (project) is accompanied by the influence of many random factors influencing the achievement of their particular goals. The proposed generalized indicator provides a dominant assessment of the effectiveness of programs (projects) taking into account the risks during their implementation.
•A car rental company consists of M available vehicles, with N currently rented vehicles, 0 ≤ N ≤ M.•The information i and entropy S = E(i) of a company are its basic measures.•The utilization, fleet ...size, and coefficient of proportionality of a company are three key metrics.•Expression for the mean profit gained by the company as a function of these metrics is obtained.•A company which is represented by the Erlang M-server loss system is investigated.
A car rental company consists of a fleet of available rentable vehicles (waiting to be rented and being rented). We model the company as a family of Birth–Death Processes (BDPs) in equilibrium with finite size, indexed by the company utilization parameter. This metric is the ratio of the primary birth and death rates in these BDPs. Relying on the basic concepts of company information and company entropy (i.e., mean information), we promote a procedure for profit management of car rental companies. The company entropy represents the company uncertainty (i.e., risk); moreover, finding optimal values of company utilization and fleet size leads to a unique management of that uncertainty. Introducing the coefficient of proportionality of a company, as ratio of the renting revenue per vehicle per day and costs per vehicle per day, we obtain an expression for the mean profit per day of a company (i.e., profit attained per day from the average number of simultaneously rented vehicles) as a function of company utilization, fleet size and coefficient. Thus, the profit management procedure reduces to finding optimal values of these three metrics, as the key profit drivers of the rental business. Moreover, an expression for the minimal value of the coefficient is introduced (as a function of the other two metrics), determining the zero mean profit per day. Thereby, the efficiency of the company's fleet is determined as a reciprocal of this minimal value. The developed procedure is illustrated on a company which is represented by the Erlang loss system.
The article studies goals and application methods of information and financial technologies in the so-called hybrid wars, which recently have become actively used by many influential countries in the ...world. Authors of the article propose scientific and methodological guide and appropriate methods for hybrid wars prompt prevention, detection, analysis and development of responding methods. Authors emphasize that recently world is opted for new, less economically costly mode of warfare rather than wars traditional methods. One of these types of wars is the so-called hybrid wars. This type of war has many aspects, but the authors of this article have focused only on one of them, the interest of which has appeared recently, namely - information and financial technologies (IFT) of conducting this type of war.
Based on this, the article discloses the content of the hybrid warfare IFT and main goals pursued by the so-called «aggressor country», and presents developed by the authors general scheme of the scientific and methodological guide for conducting hybrid warfare IFT manifestations research, which consists of the phase of identification of occurrence of the hybrid warfare IFT manifestations and three interrelated methods: methods of analysis of hybrid warfare IFT manifestations; methods of development of responding measures to the manifestations of hybrid warfare IFT; methods for developing and implementing measures to prevent the emergence of hybrid warfare IFT manifestations, etc. Article further outlines the schemes and the detailed content of these methods.
The authors of the article emphasize that in order to counteract the manifestations of hybrid warfare IFT, should be developed the measures aimed to elimination of the consequences of established negative facts, as well as to prevention the occurrence of cases which lead or may lead to their occurrence in the "target country". For this purpose, they are offered purposely deducted methodology, scheme and general content of which are presented in the article. The main which they insist on is that no grounds should be created in the country to accuse country or its authority in financial fraud. That is the only way to prevent the use of hybrid warfare IFT towards the country.
The exponential growth of the online retail sector has attracted the attention of researchers across the globe. Understanding the consumer decision-making process in an online retail context is of ...vital importance to all online retailers. The objective of this study was to examine the direct and indirect impacts of perceived risks on consumers' purchase intentions in an online shopping context. This study applied structural equation modeling to test the study model with data from 234 samples. We found a significant negative full mediating impact of performance risk, financial risk, physical risk, and psychological risk on consumers' purchase intentions. Moreover, we found a partial mediating impact of social risk on purchase intentions. However, we did not find a mediating impact of time risk on purchase intentions. These empirical results may help online retailers to better understand their consumers, their intentions to purchase, and their level of risk perceptions. Accordingly, online marketers can frame contemporary strategies to attract retail customers, leading to greater profitability of the organization.
This study analyzed the effect of fundamental information of a company such as company financial performance in the form of financial ratios, namely the coefficient of DAR, DER, ROA, ROE, OPM and NPM ...of the company's stock price in general, either in closing stock price (Pclose), PBV or PER. The object of research is the insurance companies listed on Indonesia stock exchanges until the analysis was conducted in 2013. The number of samples used is equal to the total population of listed companies until 2013, which publish their financial report, as many as nine companies. The type of data used are secondary data in a form of panel (pooled data). The period of data between 2008 and 2012. The analytical tool used is multiple regression and multivariate Formative Structural Equation Modeling is often called Canonical Correlation (CanCorr). By using Level Of Confident of between 90% to 99%, the results of multiple regression analysis (assuming simultaneous) showed that together all of these variables affect the financial performance of the PER and PBV, but had no effect on Pclose. By using Canonical Correlation analysis, the results showed statistically significant canonical variables of fundamental financial information firm canonical variables significantly influence to the financial performance of the company.
