Although plenty of scientists have researched the theoretical and practical problems of assessing knowledge potential for a few decades, the unified and single methodology of assessment has not been accepted. Discussions on the factors having the strongest impact on the knowledge potential of employees have been processed. The method stated in this article is adopted to transport sector. An evaluation of specifications for the factors making a real impact helped with building a model including such factors as educational level, occupational experience, occupation level, dutifulness, decision making and responsibility level, self‐support at work, work culture, difficulty level at work, motivation, employee's influence on achieving organization's aim and the level of using technology at work. The specifications of the above introduced factors have been prepared. Practical acceptance of the model has been researched by an experiment conducted in a transport company.

Abstract. The goal of the present article is to propose a methodology for substantiating the purposefulness of new service development reasoned by the results of a quantitative analysis of the current situation. The core of determining the purposefulness of new service development is assessing and comparing two trends of service business development: new service implementation and the main alternative of this process -the expansion of the scope of the current services. The paper demonstrates how the authors consolidate, annotate and critique available research on some logical aspects of new service development in order to find more objective quantitative decisions. The study provides the methodology (process model) of determining the purposefulness of new service development. A new attitude is evidenced by discovering quantitative assessment according to different sets of criteria. The paper also improves the comprehension of the complex process of new service implementation -proves the necessity of the first step, i.e. the determination of the purposefulness of a new service, which is often missed by authors. Appropriate solutions, according to the results of the suggested quantitative analysis, would increase the objectivity of assessment and the probability of successful new services.

Practical tasks related to property management and disposal in energy companies can be solved only if the actual property value of these companies is known. Traditional practical property valuation methods are based on the analysis of incurred property development costs or financial indicators of activities and are inadequate to account for the influence of environment factors on corporate activities and, in turn, on the value of companies. An analysis model for environment factors affecting energy companies was developed to improve objectiveness of valuation; through analysis of the model's components it is possible to analyse external macro, meso and microenviron‐ment of a particular company and to assess efficiency of such environment, as well as the impact of separate factors on value. A criteria system developed using the Analysis Model for Environment Factors and the Decision Support System for Measurement of Effect of Environment Factors on Value of Energy Companies, which was developed by the authors, were used to solve a practical task, which helped to evaluate the effectiveness of the Model of Environment Factors. The practical task included measurement of the utility degree and market value of the selected electricity companies and assessment of the impact of the criteria, which affect the environment, on the value of the selected energy companies. Santrauka Energetikos įmonių turto valdymo, disponavimo turtu praktiniams uždaviniams spręsti reikalinga tikroji šių įmonių turto vertė. Tradiciniai praktikoje taikomi turto vertinimo metodai pagrįsti turto sukūrimo sąnaudų ar veiklos finansinių rodiklių analize, jie neįvertina daugelio vertę veikiančių aplinkos veiksnių įtakos. Siekiant padidinti vertės nustatymo objektyvumą, pasiūlytas taikyti energetikos įmonių aplinkos veiksnių tyrimo modelis, kurio elementų analizė leidžia įvairiais aspektais pažvelgti į šių įmonių turto vertę ir įvertinti vertės kitimo priežastis. Sukurtas modelis leidžia analizuoti įmonės aplinką, vertinti jos efektyvumą, aplinką ir suinteresuotas grupes veikiančią išorinę makro-, mezo- ir mikroaplinką kaip visumą. Naudojantis rodiklių, apibūdinančių analizuojamo sektoriaus aplinką, sistema, pasiūlyta infrastruktūros įmonėms vertinti, taikyti daugiakriterine analize paremtus metodus. Siekiant nustatyti aplinkos veiksnių tyrimo modelio veiksmingumą, išspręstas praktinis uždavinys – taikant modelį ir remiantis daugiakriterinės analizės metodais nustatytas pasirinktų elektros energetikos įmonių naudingumo laipsnis ir rinkos vertė.
