顾客参与自助服务补救量表的构建和研究

由于自助服务的本质和特性,当发生服务失误时,服务补救的提供者不再只是企业和员工,在很多情形下,顾客也要参与到自助服务补救中来。为构建顾客参与自助服务补救量表,以网络预订为研究对象,通过理论驱动和数据驱动相结合的方法,采用验证性因子分析(CFA)和探索性因子分析(EFA)等规范的实证研究,构建了顾客参与自助服务补救量表,得到了信息搜寻、补救准备和付出努力3个维度,并阐述了该结果在营销上的应用,最后指出了研究的局限性与未来的研究方向。     

Advancing OSCM scientific knowledge by replicating empirical findings: Step-by-step procedure and illustration for transformative replication endeavors

Replication endeavors contribute to the accumulation of scientific evidence about previously reported findings and are crucial for scientific progress. Replication studies are, however, often discouraged and rarely published in the operations and supply chain management (OSCM) discipline. In this article, we offer a framework for replications consisting of two complementary tables. This framework recognizes two types of replications already defined in the literature (i.e., The Exact (EXT) Replication and the Methods-Only (MTD) Replication) and adds to these two new types (i.e., the Bounded-Conceptual-Extension (BCE) Replication and the Transformative (TRF) Replication). The framework clarifies what constitutes replications, forms of replication endeavors, and their purposes. Importantly, we also differentiate replication endeavors from reproducibility tests, robustness checks, and post hoc analyses. Moreover, we describe a seven-step procedure to guide the design, execution, and presentation of replication endeavors, illustrating these steps by conducting a TRF Replication that incorporates, at the same time, a BCE Replication and an MTD Replication of Polyviou et al. (2018). The proposed framework and seven-step procedure hopefully motivate OSCM scholars to embrace replications as valuable scientific endeavors that can yield corroborating evidence to bolster confidence in previously reported findings and, better yet, provide new nuanced findings to advance precise scientific understanding of past and new OSCM phenomena.     

Reliability analysis of man–machine systems using fuzzy cognitive mapping with genetic tuning

This article offers a method for analyzing the reliability of a man–machine system (MMS) and ranking of influencing factors based on a fuzzy cognitive map (FCM). The ranking of influencing factors is analogous to the ranking of system elements the probabilistic theory of reliability. To approximate the dependence of “influencing factors—reliability,” the relationship of variable increments is used, which ensures the sensitivity of the reliability level to variations in the levels of influencing factors. The novelty of the method lies in the fact that the expert values of the weights of the FCM graph edges (arcs) are adjusted based on the results of observations using a genetic algorithm. The algorithm's chromosomes are generated from the intervals of acceptable values of edge weights, and the selection criterion is the sum of squares of deviations of the reliability simulation results from observations. The method is illustrated by the example of a multifactor analysis of the reliability of the “driver–car–road” system. It is shown that the FCM adjustment reduces the discrepancy between the reliability forecast and observations almost in half. Possible applications of the method can be complex systems with vaguely defined structures whose reliability depends very much on interrelated factors measured expertly.
