Determination of an optimal set of design requirements using house of quality

Quality Function Deployment (QFD) has been used to translate customer needs and wants into technical design requirements in order to increase customer satisfaction. QFD utilizes the house of quality (HOQ), which is a matrix providing a conceptual map for the design process, as a construct for understanding Customer Requirements (CRs) and establishing priorities of Design Requirements (DRs) to satisfy them. Some methodological issues occurring in the conventional HOQ are discussed, and then a new integrative decision model for selecting an optimal set of DRs is presented using a modified HOQ model. The modified HOQ prioritization procedure employs a multi-attribute decision method for assigning relationship ratings between CRs and DRs instead of a conventional relationship rating scale, such as 1–3–9. The proposed decision model has been applied to an indoor air quality improvement problem as an illustrative example.     

Queues with service speed adaptations

In this paper, we consider various queueing models in which the server can work at two different service speeds. The speed of the server depends on either the number of customers or the workload. Our main interest is in the model in which service speed adaptations can take place only at the arrival instants of an external Poisson observer. Using insightful probabilistic arguments, we give the structure of the steady‐state queue length and workload distributions in the various models. In addition, in case the service speed can only be adapted right after departure instants based on the number of customers, we provide explicit and intuitively appealing expressions for the steady‐state distribution of the number of customers present.     

The maximal covering location problem with accessibility indicators and mobile units

We study the Maximal Covering Location Problem with Accessibility Indicators and Mobile Units that maximizes the facilities coverage, the accessibility of the zones to the open facilities, and the spatial disaggregation. The main characteristic of our problem is that mobile units can be deployed from open facilities to extend the coverage, accessibility, and opportunities for the inhabitants of the different demand zones. We formulate the Maximal Covering Location Problem with Accessibility Indicators and Mobile Units as a mixed-integer linear programming model. To solve larger instances, we propose a matheuristic (combination of exact and heuristic methods) composed of an Estimation of Distribution Algorithm and a parameterized Maximal Covering Location Problem with Accessibility Indicators and Mobile Units integer model. To test our methodology, we consider the Maximal Covering Location Problem with Accessibility Indicators and Mobile Units model to cover the low-income zones with Severe Acute Respiratory Syndrome Coronavirus 2 patients. Using official databases, we made a set of instances where we considered the poverty index, number of population, locations of hospitals, and Severe Acute Respiratory Syndrome Coronavirus 2 patients. The experimental results show the efficiency of our methodologies. Compared to the case without mobile units, we drastically improve the coverage and accessibility for the inhabitants of the demand zones.     

Hospital service quality evaluation with IVIF-PROMETHEE and a case study

Measuring satisfaction of patients and understanding their perceptions are important for the hospital management to respond to customers' growing demands for acceptable quality of healthcare services. The main purpose of this paper is to present a methodology that can be used in the healthcare service quality evaluation. IVIF-PROMETHEE method is applied for service quality evaluation based on patients' views in a real-life case study of a public hospital in Istanbul and the results are compared with the results from IVIF-TOPSIS method. Interval Valued Intuitionistic Fuzzy (IVIF) set is considered an appropriate tool because of the complexity and vagueness of the evaluation of healthcare services. The evaluation of the quality level of the healthcare service provides detailed information about the effects of considered criteria as well as creates opportunities in implementing effective procedures to overcome service quality problems via analysing the patients' views. The proposed methodology can be a useful tool for hospital management.     

A method towards Web service combination for cross-organisational business process using QoS and cluster

How to quickly combine various Web services to support cross-organisational business processes is the key technical problem in service computing. Because of the changeability of QoS of Web services, the traditional methods are unadaptable to the new environments. In this paper, a new service composition method, called Improved Self-organising neural network Method for Web Service Composition, is proposed to achieve QoS-aware Web service combination, according to using the clustering technology. First, fuzzy mathematics is used to express each QoS attribute and the improved self-organising neural network is used to cluster services to reduce the number of candidate services. Secondly, all the centre of each cluster is selected and formed a composite service by using an exhaustive algorithm. Thirdly, the service cluster that is represented by the concrete services. Finally, the optimal service combination can be selected using integer programming or genetic algorithm. The experimental result shows the efficiency of Web service composition and demonstrates the applicability.     

Increasing HR's strategic participation: The effect of HR service quality and contribution expectations

Strategic participation is important for HR professionals who wish to have increased influence in their organizations. While a number of previous studies have suggested a link between strategic human resource management and firm performance, few have explored the specific factors enabling HR strategic participation. This study examines the impact of HR service quality and expectations of HR contributions on HR strategic participation. A total of 244 survey responses were received from 42 companies in Taiwan. All hypotheses were supported, thus signifying significant relationships between HR service quality, expectations of HR contributions, and HR strategic participation. The study results also indicate that HR professionals are able to proactively increase the value of HR in organizations by enhancing HR service quality and addressing potential internal customers' needs accordingly. © 2012 Wiley Periodicals, Inc.     

Customer satisfaction of bicycle sharing: studying perceived service quality with SEM model

ABSTRACT

Bicycle sharing is an emerging business in many cities worldwide and has attracted a large number of users, due to its convenience, environmental friendliness, low cost, and flexibility for short-distance travels. This study evaluates main factors affecting the perceived service quality, satisfaction, and loyalty of bicycle sharing customers. We design measurement variables, conduct a satisfactory survey on customers using OFO bicycle sharing service in Ningbo, China, develop a Service-Satisfaction-Loyalty model using structure equation modeling (SEM), and conduct statistical analysis. The perceived service quality was simplified to three dimensions including: perceived service quality of platform, perceived quality of bicycle entity, and perceived quality of value. The results show that SEM model can account for commonly unobserved variables within satisfaction and loyalty of bicycle-sharing. Perceived services quality of bicycle entity and platform are found to affect customer satisfaction significantly, while perceived quality of value is not a significant factor. This study confirms that satisfaction decisively leads to loyalty of bicycle sharing.     

Enhancing the commitment to service quality through developmental and rewarding systems: CSQ consistency as a moderator

This research integrated value congruence and person–environment fit theories into a validation of the effects of developmental and reward-based interventions on frontline service employees' commitment to service quality (FLSE CSQ). Based on a dyad survey conducted in 36 Starbucks stores in Taipei, the results reveal that formal training, coaching and rewards have positive relationships with FLSE CSQ. Moreover, FLSE CSQ is positively related to job satisfaction, commitment to the organisation, job performance and organisational citizenship behaviours (OCBs). The associations of development interventions and rewards with FLSE CSQ and the relationships of FLSE CSQ with job performance and OCBs are significantly stronger when the consistency of CSQ is high.

Forecasting recovery rates on non-performing loans with machine learning

We compare the performance of a wide set of regression techniques and machine-learning algorithms for predicting recovery rates on non-performing loans, using a private database from a European debt collection agency. We find that rule-based algorithms such as Cubist, boosted trees, and random forests perform significantly better than other approaches. In addition to loan contract specificities, predictors that refer to the bank recovery process — prior to the portfolio’s sale to a debt collector — are also shown to enhance forecasting performance. These variables, derived from the time series of contacts to defaulted clients and client reimbursements to the bank, help all algorithms better identify debtors with different repayment ability and/or commitment, and in general those with different recovery potential.     

The influences of internal service quality and job standardization on job satisfaction with supports as mediators: flight attendants at branch workplace

Service organizations commonly achieve job satisfaction through internal service quality (ISQ), job standardization, and enhanced customer orientation. However, unlike employees working at headquarters, branch employees do not have access to timely responses and organizational support. This study, using flight attendants working offsite as research samples, looked at how workplace supervisor and co-worker support mediate ISQ and job standardization that contribute to job satisfaction. The results indicated that ISQ and job standardization in branch offices may, directly or indirectly, affect job satisfaction through support from supervisors and co-workers, which strengthened customer orientation. ISQ had a higher impact on supervisor support than on co-worker support, and job standardization had a higher impact on co-worker support than on supervisor support. Based on these findings, a customer-oriented model was established for the branches, and a number of suggestions on theory and managerial implementation were proposed.
