Purpose – The solvency of insurance companies is closely related to the policyholders, and consequently regulators in Taiwan pay considerable attention to this area. Several studies have demonstrated a close correlation among capital structure, operational risk and profitability. This study...

Purpose – This paper aims to propose a method for kansei value creation to be actually reflected in consumer behavior. Design/methodology/approach – Looking at business from a kansei (emotional/sensitive) value creation perspective, it is realized that currently in most cases value creation...

Purpose – The purpose of this research paper is to discuss a software reliability growth model (SRGM) based on the non‐homogeneous Poisson process which incorporates the Burr type X testing‐effort function (TEF), and to determine the optimal release‐time based on cost‐reliability...

Purpose – The purpose of this paper is to propose a new analytical approach in human thought computation with an application to the child language acquisition research. Design/methodology/approach – Certain fuzzy statistical concepts, such as fuzzy samples, fuzzy mode, fuzzy category test,...

Purpose – This paper sets out to consider the problem that the initial value of the American option is less than its fair price; this implies that the replication portfolio does not exist in the market. Design/methodology/approach – The paper develops an optimization model whose solution...

Because the structural change of a time series from one pattern to another may not switch at once but rather experience a period of adjustment, conventional change point detection may be inappropriate under some circumstances. Furthermore, changes in time series often occur gradually so that...

Purpose – The purpose of this paper is to investigate optimal decision methods under a cooperative situation in two-echelon logistic models. Design/methodology/approach – The authors propose the optimal strategies of exporters in the three types of rival game behaviors: Stackelberg,...

Purpose – The purpose of this paper is to use soft computing technique and fuzzy statistical tool to evaluate people's performance on the marketing research and time management. Design/methodology/approach – Through standardized measurement system, the authors come up with real-value data to...
