Cyclic Dynamic Evaluation of Logistics Services Stakeholders Based on System with OFN Model
The challenge for enterprises and supply chains is to deliver successful logistics services in compliance with their aims. Logistics services are affected by many stakeholders. Recognizing their impact on the undertaken services is important for the planning and execution of a sufficiently rigorous stakeholder management process. The aim of the paper is to present a new approach to the analysis of stakeholders - cyclic dynamic evaluation, which could be used in service management, such as in logistics services. We present a novel fuzzy inference system based on the mathematical apparatus of Ordered Fuzzy Numbers (OFNs). The evaluation of stakeholders consists in assessing key factors as - f…
Assessing the profitability of investment projects using ordered fuzzy numbers
Background: This article is motivated by the fact that most approaches to capital budgeting are deterministic. In reality, the capital budgeting problem is accompanied by the uncertainty and risk associated with dealing with imprecise data. Taking this uncertainty into account when performing analyses and calculations not only helps to better measure the profitability of investment projects, but also to expand the applicability of capital budgeting methods under real-life or uncertain conditions. The major contribution of this paper is the development of a novel approach to assessing the profitability of an investment project in the presence of uncertainty. Methods: We present a novel appro…
Ordered fuzzy rules generation based on incremental dataset
This paper proposes a novel approach for building transparent knowledge-based systems by generating interpretable fuzzy rules that allow for present dependences between quantitative variables by accounting for uncertainty and the dynamics of their values. In the approach, IF-THEN rules are used to show the conditional relationship between the ordered fuzzy numbers, which contain additional information about the tendencies of variables' value changes. This paper elaborates an approach of mining ordered fuzzy rules from numerical data included in an incremental database. This approach develops the ability to record uncertainty and its change in the context of rapidly changing data. In additio…
OFN Capital Budgeting Under Uncertainty and Risk
The aim of this chapter is to propose a new approach to incorporating uncertainty into capital budgeting. The chapter presents methods that can be used by an investor when the decision maker wants to be able to make an investment decision where there are alternative investment projects. This kind of problem is undertaken under the conditions of uncertainty and risk using Ordered Fuzzy Numbers (OFN). The starting point is the concept of Ordered Fuzzy Numbers. The chapter illustrates the implementation of the proposed approach with an example where two alternative investment projects are analyzed. The authors present the capital budgeting problem using a numerical example. The described metho…
SZACOWANIE CZASU REALIZACJI PROJEKTU PRZY NIEPRECYZYJNYCH ZMIENNYCH
Praca przedstawia istotę i znaczenie problemu szacowania czasu realizacji projektów w warunkach niepewności i ryzyka z zastosowaniem skierowanych liczb rozmytych. W pracy przedstawiono autorskie podejście do szacowania czasu realizacji projektów bazujące na rozmytym modelu niepewności czasów czynności projektowych ze skierowaniem. Zaprezentowana rozszerzona metoda ścieżki krytycznej jest nowym podejściem, które do tej pory nie było prezentowane w takim ujęciu w literaturze tematu. W celu weryfikacji poprawności prezentowanego podejścia przedstawiono przykład obliczeniowy ilustrujący dany problem. Przedstawiono zalety proponowanego podejścia. Podejście to może znaleźć zastosowania w praktyce…
