Quality function deployment (QFD) is a customer-oriented structural development approach. Along the gaps in the circle of service satisfaction, a new model of service quality function deployment (SQFD) has been established to develop new service. The purpose of this paper is to provide a new service development approach both in terms of academic model and practical application. A Chinese mobile telecommunication case study (tariff package design) has been employed to verify and revise the model. The findings are that, although a concise model is adopted unusual according the actual service situation, the GAP-based QFD model expands the investigative scope of GAP study from GAP 1 and/or GAP 5 to GAP1 to GAP 5. It has also been found that it is a useful tool to develop new service using a reasonable and delicate combination of Kano model, SERVQUAL scales, and GAP circle, although several further directions are presented in the latter part of the study.
Long afterglow luminescence material is an important energy storage material. For large-scale applications, the low afterglow brightness specially in slow decay process is a weak point. At present, the methods...
High-purity alumina ceramics was prepared using high-purity α-Al2O3 powder as raw material,
nitrates or oxides of magnesium, chromium and copper as additives by a wet ball milling with a later dry
pressing forming and normal pressure sintering process. The influence of additives on the sintering
temperature, microstructure and bending strength of the prepared alumina ceramics was studies. The
results showed that the additive doped with nitrate can be dispersed uniformly in the body with molecule
scale, and the oxides obtained by decomposing of nitrates have the higher reactivity. Thus, the nitrate
additives have better capacity than oxide additives in reducing the sintering temperature and inhibiting
the abnormal grain growth, and the alumina ceramics prepared by adding of nitrate additives have higher
density and bending strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
